ERCO specialises in producing engineeringhardware and software for architectural light-ing. First and foremost, we see ourselves as sell-ing light, not luminaires. This approach, whichplaces the immaterial “software” of light abovethe physical hardware of the luminaires, hasbeen the trademark of our work for many years.That’s why we call ourselves: ERCO, the LightFactory.

Light interprets spaces and helps us to per-ceive and experience them. In this sense, weconsider light to be the “fourth dimension” of architecture.

Making good architecture even betterthrough the most appropriate lighting is whatwe see as our cultural contribution and theraison d’être of our activities. Today, ERCO illu-minates museums, universities, chain stores,churches, airports, hotels, administration

buildings, private homes and much more. Irre-spective of whether the architectural conceptemphasises functionality or presentation: ourgoal is, and has always been, to find a solutionthat does justice to the specific use an d archi-tectural features of each project.

The ERCO indoor luminaires, outdoor lumi-naires and lighting control systems combine toform a comprehensive range of lighting toolsfor complete, integrated architectural light-ing solutions. The luminaire is a lighting tool,a piece of lighting equipment with a specialpractical purpose.

At a time when lighting and architectureare increasingly being looked at in terms of their energy efficiency and conservation of resources, ERCO is pursuing its "tune the light"approach to develop innovative lighting toolsthat perfectly combine efficient visual com-fort with scenographic design possibilities.This results in lighting projects implemented inoutdoor areas being publicly appreciated whiledefining effective quality standards for light-ing concepts. This brochure intends to providebackground knowledge, examples and inspira-tion for the use of light in all types of outdoorapplications.

Vertical illuminance Vertical illuminance is a character -istic feature of well-designed, eco-nomical lighting concepts. For this

reason, ERCO offers a particularly wide range of appropriate lighting tools. Vertical illuminanceusing special wallwashers is far more importantto the subjective perception of brightness thanthe light on horizontal surfaces. This is takeninto account in perception-oriented lightingdesign as an optimal solution tha t contributessignificantly to meeting the requirements of theusers of architecture and can help save energy if used in an appropriate lighting concept. So, forexample, the impression of brightness in a roomis created more efficiently using a differentiatedlighting concept which involves wallwashingthan a uniform level of brightness resulting onlyfrom direct ambient lighting. The average illu-

minance can be decreased accordingly, reducingthe required number of luminaires.

Luminaires used:3 Paratec wallwashersHIT 35WTotal connected load:approx. 105W

Energy savings: 40%

Luminaires used:5 Lightcast downlightsHIT 35WTotal connected load:approx. 175W

Horizontal lightingThe downlights createilluminances primarilyon the floor around theentrance, but also as

intersecting beams onthe wall. Seen from adistance, however, theentrance area appearsdull and is poorly per-ceived against the sur-roundings.

Vertical illuminationThe concept of wallwash-ing with less luminairesand lower energy con-sumption produces the

impression of a muchhigher ambience andimproved visibility. Thelight which is reflectedoff the wall is sufficientto illuminate the floorarea of the entrance.

Perception of verticalsurfacesDue to the natural ori-entation of our visualfield, the vertical planesof an environment con-stitute around 80% of our perception and thusdetermine our impression

of brightness.

The false colour diagramexplains the uniformityof vertical lighting. Thisquality depends on thecharacteristics of thewallwashers used and ontheir offset and spacingdistances. The detailsrequired for planning anddesign are included inthe product documenta-tion for each ERCO wall-washer.

5 factors for efficient visualcomfort

Wallwashing, impression of brightnessand efficiencyThe rule that vertical illuminances are moreimportant for the impression of brightness ina room than horizontal illuminances appliesoutdoors as well as indoors. The subjectiveimpression can be used to achieve a brighterimpression without increasing the energy con-sumption. Alternatively, the same brightnessimpression can be achieved with lower energyconsumption. In either case, the result is a nincrease in the overall efficiency of lighting. Anillustration of this is the residential entrancehall, in one example illuminated using horizon-tal lighting provided by downlights, alternative-ly using vertical illuminance from wallwashers.

client and user. In the long run, it will producesavings in both operating and maintenancecosts. Specialised, professional lighting toolsare highly efficient in achieving a specific lighteffect in a differentiated lighting concept. Theyinvariably replace several non-specific, cheapproducts, which compensates for their higherprice. Modern, efficient lamps reduce the con-nected load of the lighting system and thethermal load – with additional positive effects,such as the size and operating costs of air con-ditioning and ventilation systems. Intelligentdesigns and high-quality lighting tools ensurelighting solutions that reduce the operatingcosts while meeting all the aesthetic, func-tional and ecological requirements.

Using synergiesTo optimise efficient visual comfort in lightingconcepts, ERCO has cooperated with design-ers and users to formulate five factors whichreinforce each other and in practice result insignificant increases in light quality, resourcesavings and economic efficiency.

Efficient lampsERCO is heavily involved in thedevelopment of LED lighting equip-ment to make practical use of the

many advantages of LEDs in terms of luminousefficacy and functional life. ERCO also contin-ues to provide an exceptionally wide range of products for use with economical, long-lastingmetal halide lamps and compact f luorescentlamps.

Effective lighting technologyEfficient, precise optical systemslower the energy requirement forlighting. A comprehensive toolbox

Metal halide lampsare sophisticated, long-lasting and highly effi-cient lamps. They areavailable in many watt-ages for a wide rangeof applications.

In terms of lightinginstallations with con-trol systems such asLight System DALI, theconnected load onlyindicates the theoreticalmaximum: the actualconsumption will bedetermined through the

use of the programmedscenic dimming.

As light sources, LEDshave already achieveda significant level of efficiency and still holdfurther developmentpotential. Their extremelylong life and optimaldimmability qualify themas the sustainable lightsource of the future.

Intelligent lighting controlERCO’s DALI technology simpli-fies scenic lighting and makesit economical. Individual light

scenes to suit each situation are selected andcontrolled by the user. This is in combinationwith automated light management using sen-sor systems and timer programs which havethe potential for enormous savings. Typicalscenarios include the use of presence detec-tors to dim or switch off the light in unusedrooms, and twilight switches or analogue day-light sensors to recall light scenes commen-surate with the amount of available daylight.Particular attention is given to factors suchas ease of installation, setup and operation,which all contribute to the high level of accep-tance of these systems by the users.

Thermal managementBecause all artificial lightsources generate excessheat, ERCO’s resource-conscious thinking deter-mines that all luminairesare designed to ensureeffective dissipation of this heat. The result is thatlamps and heat-sensitiveelectronic components,

Ambient luminescence refers to uniform gen-eral lighting. This typeof lighting, e.g. throughdownlights along theperiphery of a buildingor through uniform ver-tical lighting, enablesthe user and observer toget their bearing and pro-vides a feeling of safety.

There are codes of practice andregulations for outdoor lightingthat often initially seem to restrictthe possibilities. However, this is agood thing as master plans, urbanmarketing or event concepts ofteninvolve themes and ideas that canbe communicated using both spa-tial and lighting design. A success-ful outdoor lighting concept willbe based on an understanding of the language of light.

Play of brilliantsis the decorative light,the light that resultsin surprise and amaze-ment; it is light as anaesthetic end in itself.Light effects such asdynamic colour progres-sions or light patternswith Gobo projectionsare used to create a vis-ual attraction. The samecan be said of decorativeluminaires, light objectsor neon signs whichcan provide the play of brilliants in the lightingconcept.

The Light System DALI consistsof the hardware components LightServer and Light Changer and thesoftware Light Studio. The LightServer is a DALI controller thatstores system and scene data andprovides the control functions.Day-to-day operation takes placevia the compact, wall-mountedERCO Light Changer control panelor via standard push-buttons. Toset up light scenes and for other

more complex operations, design-ers or users run the ERCO LightStudio software on a PC connectedto the Light Server or on the LightChanger via a USB connection. TheLight Server uses the DALI protocolto communicate with the LightClients, i.e. all the connected DALI-compatible luminaires, througha two-core control cable.

Master plansSimilar to urban development master plans,the same is required in the context of light-ing design to document its principles for the

after-dark appearance of urban development,city centres and even entire regions. One of theobjectives of such planning is to establish theidentity of a place and to define a concept thatmakes for an attractive appearance at night.The fundamental elements of a lighting masterplan include enhanced orientation by focusingon city entrances, landmarks and traffic routes,a concept that ensures the visibility of the cityfrom a distance by detailing the specificationsfor the silhouette, and guiding principles forthe lighting design of sites. The master plan isthen used to identify the objectives of the spe-cific project in relationship to the environment.In addition to qualitative aspects, a lightingmaster plan might also provide guidelines foreconomic efficiency, environmental protectionand road safety.

Dark SkyIn the past, the desire to enhance as manyplaces and spaces as possible using artificiallight has on occasions taken precedence overenvironmental concerns. At times, the nighthas become almost as bright as day, and thethoughtless use especially of luminaires withindiscriminate light distribution has added tothe problem of light pollution. Light pollutionrefers to the spill light that causes a disturbancein a given context due to its illuminance, beamdirection or light spectrum. Spill light and glareimpair visual comfort; information content thatwas to be conveyed fails to h ave the desiredeffect. The ecological consequences include awaste of energy and negative impact on bothflora and fauna. Dark Sky requires that lightingdesign for outdoor areas is restricted to onlythat which is essential. If this is applied, then

light pollution is avoided and for astronomers,observation of the night sky is enhanced. Th isapproach requires an effective design conceptwith a luminaire technology tailored to suit.Cooperation between lighting designers, archi-tects, landscape architects, building owners,electrical installers and luminaire manufactur-ers is required for the successful implementationof a Dark Sky concept.

Spill light can be pre-vented by using preciselighting technologyand the correct arrange-ment of luminaires to

ensure optimal visualcomfort for passers-byand drivers.

Light in the outdoorarea also provides a newview for those on theinside: vegetation whichbecomes visible increasesthe perception of exter-nal spatial depth.

Lighting master planscan be used to identifyprinciples for the light-ing design of a specificbuilding to ensure thatconsistent parametersare applied to urbandevelopment.

SmallRelatively small objects over short distancesrequire a suitably wide light distribution. Evenlow illuminances are enough to ensure good

perception. Small lamps with a low luminousflux, on the other hand, require a smaller sizeof luminaire in order that the relation betweenthe size of the object and the luminaire is bal-anced. Excessive illuminances can result inglare, particularly where smaller objects withbright, shiny surfaces are involved.

MediumLarger objects or planes require greater dis-tances and, accordingly, higher light outputof larger lamps. Consequently, the lumina ires

too are larger. To ensure optimum illumina tionof larger objects, a single luminaire is usu allyinsufficient, as large parts of the object mightotherwise be in the shadow. Often, the observerin medium-sized lighting situations remainsoutside the light beam and is not bothered bydirect glare. Precise planning makes it possibleto select the correct distance so that the lumi-naires can be installed outside the observer’svisual field.

LargeLuminaires for high light output require large,powerful lamps with appropriate reflectors. Theresulting heat generation in the luminaire calls

for large housings to ensure faultless operationof the heat-sensitive control gear. In large scalelighting situations, people might move betweenthe luminaire and the object and be disturbedby glare. Narrower beam angles in combinationwith lower lamp wattages and a greater numberof luminaires will result in visual comfort.

Very largeIn very large lighting situations, scaling throughluminaire size with constantly increasing watt-ages and lighting distances reaches its limit. A

highly efficient lamp with a wide beam anglemight well result in significant glare when apasser-by walks between the building and theluminaire. In many cases, there is insufficientspace to increase the lighting distance. Oneoption is to increase the number of luminairesto illuminate the area in sections. The narrowerthe beam width of the luminaires, the betterthe visual comfort. In open spaces, the sizeof the luminaire is usually of less importance.Installed around the base of the architecture,oversized luminaires, on the other hand, willappear to the observer to be too large.

The Powercast productgroup combines eco-nomic efficiency withflexibility in use. Themost noteworthy featureis the selection of mod-ern lamp types includingLEDs, metal halide lampsand low-voltage halogenlamps along with a mul-titude of different lightdistributions.

Powercast projectors formetal halide lamps or low-voltage halogen lamps areavailable with Spherolitreflector in 4 beam direc-tions, from narrow spot towide flood, the projectorswith LED in 3 light distri-butions, from spot to wide

flood.

The powerful Beamerprojectors are suitablefor demanding outdoorlighting concepts andensure excellent visual

comfort due to the inter-nal cross-baffle whichprovides anti-glare pro-tection. The integratedaccessory slot providesthe option of using lens-es and colour filters.

Due to its compacthousing design, theGrasshopper luminaireis suitable for discreetapplications to accentu-ate facade details, treesand plants. Efficient,maintenance-free LEDsor long-life HIT lampsensure versatile mount-ing options.

Mounting accessoriesBeamer, Focalflood andParscoop have a common,comprehensive range of mounting accessories foroptimal mounting posi-tions, either on the build-ing itself or on the site.

Lighting toolsFloodlights

The floodlights in thePowercast range generatean asymmetrical light dis-tribution due to the useof special Spherolit reflec-tors. These are availablewith metal halide lampsand low-voltage halogenlamps. The reflector canbe rotated through 360°and fixed at 90° positions.

The Focalflood range of floodlights is character-ised by horizontal lightdistributions with a focalpoint. This allows theluminaire to be placedcloser to the surfaces tobe illuminated. The rangeuses the common varietyof mounting accessoriesfor outdoor luminaires.

Due to their uniform,asymmetrical light dis-tribution, the Parscoopfloodlights are perfectfor ceiling and wallwashlighting. The rangeis highly versatile dueto its variety of housingsizes and lamps as wellas a wide range of acces-sories.

Focalflood

The Kubus facade lumi-naire is the ideal lightingsolution for a discreetidentification of detailsand entrances. The HITlamp spreads its lightwide, while the LED ver-sion produces grazinglight directed over thefacade.

The two floor washlightlighting technologiesmeet different demands:the long, oval light beamfor pathway lightingcreates a band of lightalong the path; with openarea lighting, the beamis directed onto a largerarea in front of the wall.

Features of the Focalfloodfacade luminaires arehigh energy-efficiencyand low maintenance.The DALI-compatible LEDluminaire has digitallyaddressable control gearand a narrow-beam lightdistribution to ensureuniform illumination of large areas. Mounteddirectly onto the surface,the light grazes the wall

or ceiling while reducingthe light pollution to aminimum.

Lightmark facade lumi-naires are able to illumi-nate large facade surfacesabove the luminaire – orwith double-sided frontlens, above and belowthe luminaire – with anattractive grazing lighteffect. The fully shieldedlamp ensures high visualcomfort.

Cylinder facade lumi-

naires are used both forgeneral lighting in thedirect surroundings of abuilding and to producegrazing light effects onthe facade itself. Cylinderfacade luminaires areavailable in three sizes,each with different lampsand characteristics.

Along with facade lumi-naires, the Kubus rangealso includes a bollardluminaire fitted with LEDor HIT lamps and withDark Sky technology forefficient open-area andpathway lighting. Therobust housing made of high-quality cast alumin-ium is double powder-coated.

The various featuresof the Visor floor wash-lights are also found inthe free-standing bollardluminaires of this prod-uct range. Depending onthe lamp used, they aresuitable for illuminatingdriveways, pathways,

squares, entrances orareas near to walls.

The round beam of theMidipoll is complementedby grazing light on thecross-shaped bollardprofile, turning it into aspace-defining element.Dark Sky technology andthe use of LED and HITlamps enhance the lon-gevity and economicefficiency of this bollardluminaire.

The reflector system inthe Panorama emits lightthroughout a full 360°up to 6m deep over thearea to be illuminated.Dark Sky technologyreduces the glare forpedestrians and driversto a minimum, the lampitself is only perceptibleby a slight shimmer.

The simple, yet strikingdesign of the Lightmarkfacade luminaires is alsoapplied to the bollardluminaires. Dark Skytechnology maximisesthe visual comfort andprevents light from beingemitted above the hori-zontal. With a light dis-tribution similar to theParscoop wallwasher, theLightmark facade wash-light is ideal for efficientvertical illumination.
