Introduction

This standard is a revision of the DS 700 Artificial lighting in workplaces, 5th edition, 1997-10-29. The standard includes two kinds of terms:

On the one hand the working field of vision conditions for visual presentation and comfort.

On the other hand, the surrounding space outside the actual field of work, so that visual acuity neither impeded or disturbed, and so that you can comfortably move and orient themselves.

These two considerations require planning of lighting and illumination over all surfaces, shapes, materials and colors found in the work rooms.

1 Subject-matter and scope

The standard defines methods and requirements for a safe and good design of artificial lighting in workplaces with or without daylight access from each arbejdsarters nature and conditions.

Standard requirements apply to people with normal vision. For people with visual defects or age-related vision methods can still be used, but must be made for the persons.

Standard application requires deciding on which of the listed methods and requirements to be be applicable to the current lighting system.

In Chapter 3 described a number of requirements which provide some degree of choice. In Chapter 4, the requirements unambiguous and mandatory. The standard does not include outdoor workplaces and specific work areas and places in hospitals, dental clinics and sports facilities.

3.1

The nature of light and use

Lighting impact on visual function

All visual work can be performed with more or less ease, safety and speed, depending on the precision with which the work object and its details are perceived by the eye and processed in the brain.

The interaction between light, eye and work object shown in Figure 1 below The input is the vertical visually determining factors and reading horizontally indicates the manner in which the factor is influenced by the light, partly by factors other than light.

The detail size and contrast and luminance object is interrelated in their impact. However, they have all an absolute limit, and if just one of the factors is approaching its limit, it requires disproportionate increase in at least one of the other factors in order to give a reasonable field of vision.

3.2 Adaptation and luminance

Adaptationen is the eye's adaptation to visual field luminance. It is automatic, both as a result of actual change in lighting level, and when the person moves or even move his eyes from lighter to darker rumafsnit.

For each adaptationstilstand - adaptationsluminans - are two characteristic limits, an absolute, respectively practical, dark limit and an upper blændingsgrænseområde. Above it is blændingsindtryk gradually more and more uncomfortable.

It is luminanstrinene within that range from dark to the glare, which is vital for the impression of the light in the compartment (see Fig. 2).

Visual determining factor

The eye / observer's status

Conditional of light

The eye adaptationstilstand, luminance distribution field of view, any glare, and (more rarely) the luminance, the eye had previously endured.

Without influence.

Light geometry in interaction with the object surface properties.

Illumination. When light colored objects color. By specular objects emitter and ambient luminance.

Conditional on other factors

Individual circumstances of the observer (Normal / abnormal vision, optical correction, visual system age, fatigue, influence of drugs or alcohol).

The detail actual size, viewing distance and any optical aids, such as magnifying glass.

Surfaces reflection and reflection characteristics and three-dimensional structure.

Surfaces reflection and reflection characteristics and the object's three-dimensional shape.

The detail size

The detail contrasts

The object's luminance

The object's motion By pulsed light, the perception of movement distorted.

Movement nature (direct or projecting) and speed or frequency.

Regular or irregular, pending or unannounced appearance. Place within the field of view.

(The movements of the work object decreases always the visibility of details). Individual circumstances of observer (visual field extent and possible change).

Figure 1 - The interaction between light, eye and work object

Are luminance completely smooth with few luminanstrin, the light in the room monotonous.

If the distribution vary significantly from light to dark, the light in the room full of contrasts possibly at risk for glare from luminaires.

Suddenly transition from small to large luminance or vice versa, and big jumps between visual field luminance, can cause glare or reduced visibility.

As a rule, a variation with seamless luminance, both in space and in the work area may be preferable. If there is more room surfaces with distinctly different luminance and a sharp transition, protrusion may not exceed 3:1. Less surfaces and shadows may, however, be luminansspring up to 15:1. For reasons of eye function, it is best to synsobjektets luminance is higher than the working area, which again be higher than ambient.

In space, there is in open communication with each other, they must be decisive luminance should not exceed 25:1.

Figure 2 - Luminanstrin from dark to glare

The relationship adaptationsluminans / objektiuminans shown in grayscale to illustrate the gradual change from dark to light.

The horizontal (highlighted) axis is adaptationsaksen, 0.3 to 10,000 cd/m2 (ie from dusk to midday sun on a bright sandy beach).

Over axis Linde's the brighter (positive) objekluminanser. During axis are similar to those darker (Negative) objektluminanser. The horizontal lines indicate how much brighter (x 101, x 102, etc.) or darker (X 10-1, x 10-2, etc.) objekluminanserne is (ie, how much should be multiplied by).

For example, at 100 cd/m2 adaptation - that's approximately 300 lux at pupilplanet - the practical dark boundary being approx. 10-2, the incipient unpleasant about. 101, and the full glare approx. 102 x adaptationsluminansen provided blændingskilden is approx. 10 ° x 10 °.

Figure 3a Figure 3b

FIG. 3a and 3b show two rooms with extremes within the acceptable differences in relative reflectance / resulting luminance.

The two characters are drawn as spherical perspectives - a afbildningsform, which includes the entire half space in front eye, much as fiskeøjefotografier.

NOTE - The detail to be seen, it is difficult to make larger (only for a closer view or magnification). Therefore, it is important that differences in luminance between the detail and its surroundings are present.

These differences are reflected in two ways:

-

-

By contrast in the illuminated surface: Dark compared to the bright, glossy compared to the matte, neutral colored compared to coloreds, and

due to the contrasts in surface material nature: smooth or rough, flat or three-dimensional, with geometrically ordered or random built structure.

This will not only light source luminance, but also its solid angle and light main direction is essential for:

-

-

-

-

Contrast Reproduction of text and figures on paper, because it mainly depends on luminansforholdene in the part of space that is about mirroring direction from paper to mind.

Material Perception involving gloss because it can only be considered if there are clear differences between light and dark areas in the surrounding velserne. In very diffuse lighting can mirror objects look as if they were dull.

Perception material, which is dependent on småskyggers uniqueness in terms of the principal direction with respect to the difference between illuminated and shaded.

Object Perception, where larger and more complex social objects requires a balanced shadow and shine drawing in both the main form of detail and texture.

3.2.1 Control of Luminance

Displaying a review of the resulting luminance of the room elements (walls, floor, ceiling, furniture, of work, etc.) a luminansmønster, which corresponds to the character you want to give space?

Is there impermissible big jump in luminance between adjacent larger surfaces, respectively sharp boundary between surfaces with very large luminansforskel?

The color properties

the color of light, ie. the color with which the light is seen

as color reproduction, ie. light's ability to reproduce colored surfaces.

Shows the spectral characteristics of light in two ways:

NOTE - Light emphasis on micro texture is directly related to the color temperature. It is the experience that the higher the color temperature the more spread light in the microstructure, the lower the color temperature the less. Texture drawing is a variation from clear to blurred sign texture.

3.3.1 Colour Light will - where it is not about the actual colored light - usually described as cool colored, neutral colored or highly colored. As a clarification used the color temperature (in Kelvin), which is the each light source almost.

Kelvin figures is a pure numeric scale. Equivalent to lysfarveopfattelsen used a reciprocal scale where equal intervals corresponding to equal differences in color perception (Fig. 4).

Kelvin scale is a temperature scale, defined as + 273 ° Celsius corresponding to 0 K.

The subjective perception of this physical scale, a second regularity shown on the lower scale. From ~ K to 2000 K can be seen 500 equal steps. This should be understood as such in relation to 3333 K works 5000 K as cool as 3333 K works in relation to 2500 K.

NOTE - Experience shows that there exists a correlation between the preferred light color and lighting level. Spaces with higher illumination combined best with cooler light. Rooms with a lower illumination reverse best with warmer light. But the rule is not unique. It must be assessed in relation to the size of compartment, use and color scheme.

3.3.2 Rendering The color rendering properties listed with color rendering index Ra, which is a reflection of a light source ability to reproduce colors correctly. The highest possible value for Raindekset is 100

Good color reproduction is crucial for many visual tasks. Reproduction of human skin and colors in the environment is of importance to whether the space is perceived as pleasant to be in.

Section 4 provides the requirements for the R-value that can be accepted for individual workplaces. As a main rule, be used Ra values above 80 in rooms where people staying in extended periods of time. Exceptions can be very high-ceilinged halls, where one must ensure that fixed workplaces locally is illuminated by a light source with a better color reproduction. Safety colors shall be all circumstances be recognizable.

NOTE - Colour reproduction is a function of both adaptationsniveau, color temperature and spectral characteristics of light.

Even in daylight (which has temperaturstråleres continuous spectrum) will be at the same level be clear differences in light of different color vetemperatur. For example, experience shows that cool-white light, 5000-8000 K, gives a more reliable basis for color assessment and color sort of, for example fur, textiles and tobacco products. The same goes for painting halls and artist's studio.

Newer artificial light sources with non-continuous spectra can have a light color similar to that of a temperature-rays, yet one color reproduction, which is quite different.

It has therefore been internationally adopted an accounting procedure for 8 medium bright surface color indicates how much their appearance change / shift in relation to the appearance of light from a temperature-rays with the same color temperature. The average of these eight color shifts, Ri (i = individual) results in the color rendering index R (a = average). The scale goes from 100-0. 100 is the ideal temperature rays, 99 is an incandescent or halogen bulb. Fluorescent occur in three groups: R 95-90, R 80-85 and R 65-55.

It noted that although the light drawing of micro texture is directly related to color temperature, CRI value no direct expression for this property.

Some studies suggest that there is a reciprocal linear relationship between light sources CRI and the necessary lighting tion level, where the total visual brightness of a room should be kept constant. R-value of 50 for example, require almost a doubling of the level of

compared to the 100th R The studies described in "Lighting Research and Technology", No. 1, 1977 and in "CIE Proceedings", 1979, see Annex B.

3.3.3 Checking the color properties The color properties are assessed by two independent criteria:

a) immediately observed light color (eg hot / cold):

Equivalent color of light for general illumination and the site's use (concentrated work recreation, etc.)?

b) The color rendering properties:

Color reproduction is satisfactory, especially for the specific space activities, such as color rating, but also with regard to the natural appearance of facial color wood surfaces, etc.?

3.4 Shape Drawing, shadows and shine

The shape of any spatial object is perceived as a result of either shading or shine drawing. On the bright surface will be shaded drawing of greatest importance. On dark surfaces will shine drawing be most visible. In most cases, the form is perceived by a combination of shadow and brightness.

3.4.1 Planning of form drawing The basis for such drawing is a combination of luminance and geometry. In its simplest form, only the luminansforskel because of stronger and weaker respectively light from the main light source, respectively rumoverfladerne. In more sophisticated version with careful consideration of both solid angle and luminance.

- Principle applies to any point on a surface receives light from the half-spaces that are above or the front surface. If this half-space has a completely smooth and uniform luminance distribution, the light in the point diffuse. I.e., without the possibility of real shading and with a marked low shine (Fig. 5a).

If half the room only sends light from a very small, confined area, the light on the surface parallel, ie. with the possibility of quite sharply drawn shade and distinctly punctate, possibly blinding reflection (Fig. 5c).

Increasing the luminous area of the half-space to a larger delimited area, - that is to say, the solid angle is increased - is the light on the surface less directed, shadow consequently less sharply drawn and the mirror a little less hard (Fig. 5b).

-

-

In practice, the two extremes be avoided, but nearly parallel light may be suitable for enhancement of small objects, and texture and almost diffused light may be suitable for the illumination of larger room surfaces.

Otherwise, shadow types, located in an area between the two outer areas be generally useful. In the case of where desired forming shadows, a ratio of about 4:1 between the direct and the indirect light may be appropriate.

Figure 5a Diffuse lighting

Figure 5b Delimited lighting

Figure 5c Parallel light

NOTE - Theoretically, there are many intermediate forms between the fully corrected and completely diffused light. However, if the light source is more or less concentrated - round or rectangular, with an axis ratio of more than 3:1 - there will in practice is unlikely to be more than 10 to 12 kinds, if their effect could be distinguished from each other. Increasing the axis ratio substantially beyond 3:1 (as is often the case with a fluorescent lamp), the shade drawing differ. Shadow of objects arranged in parallel with armaturretningen will be apparent, while the inverse shadows from objects located on the across armaturretningen will be almost obliterated.

Form drawing must have smooth transitions from light to dark approximately equivalent to luminansgradueringen 3:1.

Therefore, light sources physical size and spaced according to the size of the illuminated - from very small texture detail to fully large inventarmaskinopbygninger. A task light over a management console for example, will be locally about the same shade drawing as a well-organized group of fluorescent lamp placed over a large lathe. The emitter perspective size, which makes shape drawing.

3.4.2 Checking the shadows Are there local shadows (shadows from machinery, etc., hand or head shadows of persons) impairs visual conditions at work?

Are some shadows so deep (dark), they are annoying? Is the sharpness of the shadow contour under control?

Have some shadows (if the light comes from a point source or from a parallel beam fixture) bothersome sharp outline?

Is there by individual line-shaped light sources shadow from certain edges and not from others?

3.5 The main direction of light

Light the main direction determines whether shine and shadows seem kind signatory or just distracting.

3.5.1 Planning the main direction Where practicable, the lighting system disposed in such a way that there is a clear main direction and thus shadow signatory light distribution over the working area.

Contrasts on paper highlighted when reflections in the paper avoided.

Even bright light from two sides will always be formopløsende and texture blurring.

Faces seen best when illuminated obliquely from the side with a main direction from 15-45 ° above horizontal and also front 45-75 ° from the visual axis, so that the shape becomes three-dimensional without too much contrast between face two sides.

3.5.2 Control of the main direction of light Of great importance in order to achieve the best possible contrast is the direction from which the light from the different luminaires falls on surfaces and objects, which concentrated / scattered light is, how much luminaire luminous surface seen from below visual object and any light color and light color reproduction, this checked.

Are there reading, writing, drawing, etc. such lysindfaldsretninger (usually obliquely from the front of above), to an appreciable reduction in the contrast occurs?

If the light on the individual spatial objects in space (eg people) a sufficiently clear dominant direction to form not blurred? Where it comes specular objects are mirroring of the surroundings, such as the a storfladearmatur, is often important.

Seems that on some surfaces (eg paintings) one at once stray and highly targeted light on undesirably emphasizes unauthorized irregularities in the surface?

3.6 Movement and flicker

Some light sources that are connected to AC power pulses of light emission.

3.6.1 Planning for motion and flicker This pulsation perceived under specific conditions as flicker.

The eye's ability to perceive the flicker is greater in the peripheral visual field, and depends on many factors. The main are luminance, since the higher this is, the higher the frequency the eye can perceive as a single glimpse. Flicker can really uncomfortable and annoying flicker must be limited by appropriate measures.

Pulsation in the light emission gives rise to the so-called stroboscopic effect, thereby rotating or fast moving parts speed - and possibly rotation - errors can be assessed. In these cases, the measures are taken to eliminate the risk of stroboskopeffekten example, by the use of high-frequency operation or by the use of any special couplings of the light sources.

3.6.2 Control of motion and flicker Is there a risk of annoying flicker or strobe? Are there any annoying flicker in the peripheral field of view?

Are there any rotating machinery where the light gives rise to misjudgment of stagnation / rotation?

3.7 Lighting Strengths / regularity

Section 3.2 refers adaptationens and luminansernes essential for visual function. By designing with light forces ensured that luminansmønsteret is acceptable under normal conditions. This lighting design must be made and is then used as the basis for an assessment of luminance.

NOTE - Lighting strength of 50, 100, 200, 300, 500 and 1000 lux, is approximately equal to the luminance of 10, 20, 40, 60, 100, and 200 cd / m bright surfaces such as white paper. This comparison establishes ties illumination to grayscale in Fig. 2, section 3.2.

3.7.1 illuminance on visual object and space In Chapter 4 of the alphabetical list of workplaces and species are listed the values of illuminance, within the tolerance range must be present on the visual object - and in its level - all the time, even after placement of machinery, equipment, furniture, etc.. Special lighting can be an appropriate solution to this requirement.

NOTE - Furniture DRAWING influence on the lighting level is treated in CIE Publication 161:2004, Lighting design methods for obstructed interiors, see Appendix B.

In addition illuminance on visual object and its immediate surroundings must also be assured that there is a adequate lighting in the room, in the interest of luminance, safety at road, cleaning and overall well being, have been met.

It is generally not desirable for the stated illuminance of visual object is present in the room, the viewing conditions are generally most favorable when the surroundings are less bright than the object itself, and it is particularly important that the illuminance on the working field's immediate vicinity is not higher than the the working area.

In figure 6 is indicated levels of general illumination in the room relative to the illumination on visual object. Values are operating values and refers to a horizontal plane 0.85 m above the floor. For lighting forces in space, the same R-value as the lighting on visual object specified in Chapter 4th See also Figure 1, the interaction between light, eye and work object.

Working Field closer and farther surroundings and traffic areas are often divided into zones where each Zone requires a uniformity of 20% to 70% (min. / max.), so that the average illuminance of each zone corresponding to those in Fig. 6 stated values.

3.7.2 New value, service value and maintenance The values of illuminance, which can be expected to be present in a brand new facility (replacement value), is not crucial, as these values will not be present all the time. A number of factors leads to a decrease in illuminance (operating value), and nyværdierne must therefore be correspondingly higher than the specified values. Replacement value of illuminance, which determine the number of luminaires and lamps and for electricity consumption during operation, the operating value divided by the maintenance factor.

The standard values specified for the illumination is operating values and must be based on project planning. This means that the indicated illumination within a tolerance range is a absolute minimum value for any point in the working field, and it must be ensured that this illumination is to present at any time in the operating cycle. The numerical values are used as design travel sizes planning. For reasons of practical design and operation and maintenance of a lighting system can a tolerance of 25% below the numerical values of individual points within the working area.

The relationship between the operation value to be expected because of the foreseeable reductions and replacement value, called the maintenance factor.

This depends on

-

-

-

-

light sources luminous flux

soiling and aging of lamps and luminaires

soiling and aging of the room's surfaces

maintenance mode (single replacement or group replacement and time between group replacement and - cleaning).

Maintenance factor shall be calculated as set out in Section 3.12. Maintenance factor is dependent on the maintenance routine. It is essential for the construction and operating costs and resources to implement a rigorous maintenance routine.

NOTE - Maintenance routines are specified in LTL-Report No. 31: "Maintenance of lighting system", see Annex B.

3.7.3 Control of illumination / regularity of general and special lighting Satisfied with the system requirements of the task to either high evenness or vice versa differentiation with emphasis important / active areas in relation to secondary / passive?

Provides facility adequate illumination for use and cleaning the room?

Provides facility along with any task lighting sufficient illumination on visual objects?

3.8 Glare

There are two types of glare, both of which should be limited.

3.8.1 Sight restrictive glare - Sometimes called physiological glare - due veiling spread in the eye, especially from sources near viewing direction. This means that the impact on adaptationsluminans and thus on the eye contrast sensitivity.

NOTE - Sight restrictive glare will rarely be a problem under normal lighting. However, it is possible to calculate it by a method specified in the "Indoor LIGHT", which also set a recommended limit, see Annex B.

3.8.2 Unpleasant - Sometimes called psychological glare - is the sensation of discomfort and irritation caused by a light source of high luminance with respect to a darker background.

Characterized by unpleasant glare, as shown in either NB-or-UGR method both can be used in the calculation.

NOTE 1 - NB method (Nordic Lighting Calculation) expected to be replaced by the UGR method (Unified Glare Rating), which is a internationally recognized method for calculating unpleasant. The two methods can yield results of minor differences.

Note method described in "NB method. Calculation of indoor general lighting", while the UGR method described in CIE Publication No. 117, and in "UGR method. Addendum to NB-method", see Annex B.

In both methods are assumed to glare calculated with nyværdier for luminaire lysstrømsudsendelse.

Requirements for lighting performance in terms of reduction of unpleasant is the standard set by a maximum glare.

NOTE 2 - glare indicated on a scale which, in practice, going from 13 to 28, where the largest glare indicates the strongest glare. The smallest difference in glare, providing a noticeable difference in glare, the third

The in section 4 below max-glare must be respected in the workplace.

The max-glare for a working mode thus provided at 23, it means that a glare to 23, it is highest acceptable.

Glare shall include all fixtures in general lighting system and may include other fixtures with preset, which contribute to the unpleasant to work.

NOTE 3 - It is noted that adjustable work lights can cause a significant unpleasant.

General Lighting Construction glare defined as follows:

In the cases in which the jobs are bound to viewing directions either longitudinally or across the room, determined glare of the viewing direction. In the other case, the glare for both viewing directions taken into account.

In cases where the location of jobs may be due account to avoid positions with particularly strong glare can middelblændingstallet used. Otherwise, the maximum glare used.

3.8.3 Control of glare Is there (regardless of a summary blændingsberegning the system as a whole) risk of local glare from individual luminaires or particularly bright surfaces or reflection in shiny surfaces?

3.9 The combination of artificial light and daylight

When daylight is insufficient, there are basically four options to supplement with artificial lighting, and the have different advantages and disadvantages.

NOTE 1 - Additional artificial light from fixtures located above the window.

Advantages: There will be no conflict between the direction of the light from the 2 types of light, although there will be a bias in the mixture of the two colors of light. If the lighting enhances the luminance of window wall, the glare from the window will be reduced.

Cons: No daylight can cause a distribution of light in the room that works for skewed. The use of luminaires with asymmetrical light distribution that sheds light into the room, the risk of glare.

NOTE 2 - Additional artificial light from fixtures in a zone behind the room.

Advantages: In deep space evened the great contrasts between the window area and the deep space.

Cons: In the zone where daylight and artificial light are mixed, the light will come from 2 directions and have different color of light.

NOTE 3 - Supplemental artificial light from all fixtures in general illumination.

Advantages: Although direction of the light from artificial light will weaken daylight positive attributes, it will be the combination of lighting and daylight, allowing the fewest drawbacks. In deep space, the additional lighting to reduce glare from windows.

Cons: Different color of light from daylight and artificial light.

NOTE 4 - Supplementary lighting at the individual workplace.

Advantages: Colour difference between the daylight and the concentrated artificial light does not bothersome, and daylight positive attributes is maintained in the space.

This is the optimal solution, with room lighting not turn on until the backlight level is too low.

Cons: None.

3.10 Checking the power demand and energy needs

Is the lighting system energy consumption and power demand sought limited as much as possible, taking into account space design and use, including requirements for lighting quality and runtime?

Is there an appropriate division of the lighting system in zones with manual and / or automatic control or regulation of each zone, ie. with the possibility of immediate surroundings and activities?

NOTE 1 - The SBI instruction 184 is zoning of lighting systems mentioned, see Annex B.

3.11 Checking the requirements for lighting

Lighting systems can be controlled in two ways:

One is to check that the lighting system design travel data are consistent with the assumptions that formed the basis for the design.

NOTE 1 - There can be required to design travel data shall be based on accredited testing.

The second consists in measuring and assessing the lighting.

NOTE 2 - Lighting strength and luminance can for example be measured as described in LTL-Report No. 32 "Measurement of illumination and luminance of the lighting system ", see Annex B.

3.12 Maintenance of lighting systems

3.12.1 Planning of maintenance by design Vedligeholdelsesfaktorens size is essential for plant economics and energy consumption. Therefore, the following a substantial part of a design work:

- Select fixtures and lamps that also takes maintenance conditions

- Select a maintenance way that balances the lamp replacement costs with economic and energy impact of maintenance factor

- Depending on the chosen lamp, fixture and maintenance way to find proper maintenance factor (see the following Table 1 and Table 2)

- In project delivery to provide information on maintenance factors and assumptions in the form of an assumed maintenance means.

It will most often at greater lighting be an advantage - both lighting technical and financial - to make replacement of all light sources at once (group replacement) simultaneously with a cleaning luminaires.

Determination of maintenance factor V: The overall maintenance factor is:

V = Vlyskilde × Varmaturtilsmudsning × 0.95 (Vrumtilsmudsning)

In the absence of data for luminous flux for the current light source can Table 1 is used.

In Table 1, the part of the maintenance factor, which corresponds to the lamp the total luminous flux Vlysstrøm, indicated taking is assumed that the lamps burn out before any group replacement, individually replaceable. Factor depends on the lamp type lamp the annual operating time, and if you only want to simply replace the lamps, or we want also to group replace the lamps with a specific interval.

In Table 2, the part of the maintenance factor, which corresponds to the fouling of the luminaires Varmaturtilsmudsning expressed depending on the desired cleaning frequency group, armaturtypen, and the surroundings are clean or dirty normal stopped.

Contamination of the room can be a good approximation recognized by a factor of 0.95. For a more accurate description, for example, by indirect lighting, which factor is typically around 0.75, refer to the data in the CIE Publication No. 97, see Appendix B.

Table 1 - The part of the maintenance factor, which corresponds to the lamp the total luminous flux

(The lamp the luminous flux obtained from the CIE Publication No. 97)

NOTE - The specified types of lamps are of type "classical light sources". In recent cases and new types of lamps must relevant data sought informed in lamp manufacturer.

Maintenance factor at gruppeudskifning is determined from data collected from typical lamp types within the category.

Maintenance factor at single replacement is intended as a maintenance factor at the hour for the light source has burned half of its total lifetime.

Table 2 - The part of the maintenance factor, which corresponds to the fouling of the luminaire according to of armaturtypen, surroundings and group cleaning interval.

(CIE Publication No. 97)

3.12.2 Maintenance of lighting systems in operation Good maintenance of the lighting system reduces wear and tear, ensuring that lighting quality is maintained and thus provides safety, functionality and comfort while minimizing energy consumption and investment needs.

Lighting systems should be cleaned and serviced regularly and room surfaces cleaned or re-painted with appropriate intervals. Service intervals must be adapted, so as to ensure that the illumination does not become lower than the operating value of the illuminance that is required.

For new lighting system followed the assumed maintenance plan, which will be available for design work, and to ensure that the condition of the used maintenance factor is observed.

4 Requirements for illumination, blændingsgrænse and color reproduction. Alphabetical list of workplaces and Species

Where a workplace or work type not listed, please refer to the most similar work or the most similar work mode. A dash in the table indicates that a numerical value is irrelevant.

All numerical values apply at any time in the operating cycle.

Visual Task with special requirements for lighting form (see Annex A) Illuminance as general lighting - marked with a *. Other value- values are illumination on visual object - see also 3.7.1 (Figure 6)

Figure 8 - Table of characteristics of lighting to achieve optimum contrast at different visual tasks

A.1 Specification of the visual task 7

By lighting of workplaces with visual display units may require special attention in order to avoid annoying reflections in the screen while you get a good contrast between text and background on the screen and an appropriate luminance distribution in and around the workplace.

A.1.1 Contrasts The contrast between text and background on the screen is crucial for readability. It may normally be within certain limits are set on the screen. Lighting systems must be designed to avoid excessive lighting directly on screen. All kinds of reflexes, also reflections of evenly illuminated surfaces will reduce the contrast and therefore avoided.

A.1.2 Reflexes in the screen Reflectors can come from windows, lighting fixtures, bright surfaces in the room or from the operator himself.

Reflections from windows can be avoided by proper placement of the screen or by sealing off windows. By viewing direction parallel to the window wall has a better opportunity to avoid reflections in the screen.

It is important to avoid reflections in the screen from fixtures. This can in most cases be achieved by use of specially foreclosure and partial uplighting fixtures that are placed correctly in relation to the screen. In certain cases the local shielding of the workplace be an appropriate measure.

To reduce reflections from surfaces in the room they must not be too high luminance, and particularly strongly lit areas must be avoided.

Reflexes of the operator itself can be particularly troublesome, because the reflectors moving, and the focusing distance is uncertain. The problem can be reduced by using not light clothing and at low illuminance of the subject.

A.1.3 luminance In order to get a proper luminance ambient luminance should be of the same magnitude as the luminance of the display, papers and worksite other surfaces. Windows and sunny or very bright surfaces must not occur in the visual field.

The surfaces immediately surrounding the screen in the viewing direction is particularly important for obtaining an appropriate luminance distribution. These surfaces must therefore have an appropriate luminance, obtained for example by suitably combining reflectance and illumination.

Illuminance on any manuscript must be chosen as a compromise between that on the one hand must not have excessive luminansspring to the screen, but on the other hand, it must have sufficient illumination to read the manuscript. Depending on the need for script reading recommended illumination at work between 200 and 500 lux.

A.1.4 Summary of Section A.1 Problem Cause

Windows

Faucets

Room surfaces

Solution

Proper placement of the screen. Possible foreclosure of the window. Proper placement of the fixture relative to the screen.

Specially shielded and possibly partial uplighting fixtures.

Background with constant luminance. Limited reflectances.

Operator

Poor luminance- sharing around the screen

Room surfaces

Manuscript Contrast degradation in screen

Reflexes

Windows in field

Limited illumination. Dark clothing.

Lower illumination on the operator. Proper placement of the screen (Viewing direction parallel to the window wall). Appropriate combination of reflectances and illumination.

Illuminance as needed (200 - 500 lux). Avoided as described under "reflexes in the screen".

Reflective screen

In bright daylight on the screen location screen not too close to windows - or shielding of dagsl s Excessive artificial lighting is not too high illumination in general. Appropriate lighting distribution on display
