Lighting?
“Lighting or Illumination is the deliberate application of light to
achieve some aesthetics or practical effect. Lighting includes use of
both artificial light sources such as lamps and natural illumination of
interiors from daylight. Indoor lighting is a key part of interior design.
Lighting can also be an intrinsic component of landscaping.”
Lighting Principles & Terms
Illumination
The distribution of light on a horizontal surface.
The purpose of all lighting is to produce
illumination.
Or in other words, it is the luminous flux per unit
area on an intercepting surface at any given
point.
Lumen
A measurement of light emitted by a lamp. As
reference, a 100-watt incandescent lamp emits
about 1600 lumens.
We used to look for
Now we look
for
Footcandle
A measurement of the intensity of
illumination. A footcandle is the
illumination produced by one lumen
distributed over a 1-square-foot area.
for different types of working the
varied amount of footcandles of
illumination. (can be seen on next

Lux
It is the amount of illumination created
by a light source of 1 candela which is
one metre (1m) away from the surface.
One LUX is equal to ONE LUMEN/
SQYARE metre.
1 Lux = 1 lumen / sq. m.
Efficacy
The ratio of light produced to energy consumed. It’s
measured as the number of lumens produced divided by the
rate of electricity consumption (lumens per watt).
Colour Temperature
Outdoor / Indoor
Defined as the tone of light or how the light
looks in terms of whiteness.
Higher the colour temperature = whiter/cooler
the light source.
Unit measurement = Kelvin (K)
Colour Temperature
Outdoor / Indoor
Colour temperature is a characteristics of visible light. In practice,
colour temperature is only meaningful for light sources that do in
fact correspond somewhat closely to the radiation of some black
body.
The colour temperature of the electromagnetic radiation emitted
from an ideal black body is defined as its surface temperatures in
KELVINS.
Colour temperatures over 5,000K are called cool colours (blueish
white), while lower colour temperatures (2,700-3,000 K) are called
Warm colours (yellowish white through red).
Colour Temperatures
CRI (Colour Rendering Index)
The colour rendering index (CRI), sometimes called colour rendition
index, is a quantitative measure of the ability of a light source to
reproduce the colours of various objects faithfully in comparison
with an ideal or natural light source.
Colour Rendering: Effect of an illuminance on the colour
appearance of objects by conscious or subconscious with their
colour appearance under a reference illuminant.
Finishes should be evaluated under the type of lamp (lamp and/or
daylight) which will actually be used in interiors.
Colour rendition depends on lamp colour spectrum, reflective
property of surfaces and context and condition in room.
Judgement of apparent surface colour depends also on the
experience and expectations of an individual with normal colour
vision.
CRI (Colour Rendering Index)
Glare
The excessive brightness from a direct light source that
makes it difficult to see what one wishes to see. A bright
object in front of a dark background usually will cause glare.
Bright lights reflecting off a television or computer screen or
even a printed page products glare. Intense light sources –
such as bright incandescent lamps – are likely to produce
more direct glare than large fluorescent lamps.

What is Incandescent Lamp?
Hot wire – Filament sealed in a Glass Jar (Bulb).
How it Works?
Electric Current pass through the wire n make it heat
it to incandescence, and the wire emits light. Use
Standard Voltage Circuit.
Incandescent Lamp
Incandescence?
Inside the glass is a gas such as argon and/or
nitrogen. At the center of the lamp is a tungsten
filament. Electricity heats this filament up to about
2,500 degree Celsius. Just like any hot metal, the
tungsten gets “white hot” at that heat and emits a
great deal of visible light in a process called
incandescence.

Lamp Life Time:
1. Standard-Life Lamp: high temperature for the filament to operates, emits
more light, shorter life time – “burns out”.
2. Long-Life Lamp: given wattage produces less light, designed for longer
life.
Lamp Efficiency = Light Produced (Lumens, lm)
Electricity Consumed (Watts W)
Light Output: Insert Gas (Argon, Nitrogen, Krypton) slows bulb bickering
caused by condensation on the bulb wall.
Incandescent Lamp
Bulbs are sold by Watts – Measure of Power Consumed.
Lumen tells how much light lamp emits.
Hours of Operation is produced life-time (750 – 1000H, up to 2500H
for extended service lamps).
Energy Saving Lamps – Reduced wattage, Reduced light output.

Tungsten - Halogen
What is Tungsten - Halogen?
Selected gas of Halogen Family.
How it Works?
Halogen gas combines with Tungsten
molecules that sputter of the filament deposits
Tungsten back on the Filament and Emits
constant level of light.
Tungsten - Halogen
How Halogen bulb emits light ?
A halogen bulb has a filament made of Tungsten,
which glows when electricity is applied, same as
regular incandescent bulb.
The halogen gas removes the carbon deposits on
the inside of the bulb, caused by the burning of the
tungsten filament, and redeposit it back on to the
filament, resulting in a light bulb which can be burnt
higher.

Low-Voltage Lamps
Low-Voltage Lamps – incandescent and
tungsten-halogen lamps that operate between
6V and 75V.
Standard building current of 115V – 125V must be
stepped down by the use of transformer.
Low-Voltage luminaires with integrated
transformers are larger in sizes and bulkier.
Practical system is line-voltage equipment.

Coloured Light Bulbs(Coloured Ceramic Enamel)
Coloured Filters
HUE (quality in red or green),
SATURATION (strength or depth of colour)
BRIGHTNESS (quantity of light)
Gelatine Filters (“Gels”)
Thin transparent coloured plastic sheets in wide variety of
colours, as well as multi-coloured and diffused sheets.
Short service life – colour fades rapidly.
Interference Filters
One or more layers of ultrathin film coating on clear glass
that reflects rather than absorb unwanted wavelength.
They transmit one colour, and reflect the complementary
colour.
Discharge Lamps
What is discharge Lamp contains?
Gas, phosphor, cathode, discharge.
How it Works?
Light is produced by passage of an electric
current through a vapour or gas, rather than
through a tungsten wire as in incandescent
lamp.
Fluorescent Lamp
Fluorescent Lamp
The classic fluorescent lamp design, which has fallen mostly by the
wayside, used a special starter switch mechanism to light up the
tube.
The conventional starter switch is a small discharge bulb, containing
neon or some other gas. The bulb has two electrodes positioned
right next to each other. When electricity is initially passed through
the bypass circuit, an electrical arc jumps between these electrodes
to make a connection. This arc lights the bulb in the same way a
larger arc lights a florescent bulb.

High Intensity Discharge Lamps
(HID Lamps)
Type of electrical gas-discharge lamp which produces light by
means of an electric are between tungsten electrodes housed
inside a translucent or transparent fused quartz or fused alumina arc
tube.
This tube is filled with both gases and metal salts. The gas facilitates
the arc’s initial strike. Once the arc is started, it heats and
evaporates the metal slats forming a plasma, which greatly
increases the intensity of light produced by the arc and reduces its
power consumption. High intensity discharge lamps are a type of
arc lamp.

LED & OLED
A light – emitting diode or LED, is a semiconductor light source. LEDs
are used as indicator lamps in many devices and are increasingly
used for other lighting. Introduced as a practical electronic
component in 1962, early LEDs emitted low-intensity red light, but
modern versions are available across the visible, ultraviolet and
infrared wavelengths, with very high brightness.
White Light
There are two primary ways of producing high intensity white-light
using LEDs.
1. One is to use individual LEDs that emit three primary colours – red,
green, and blue- and then mix all the colours to form white light.
2. The other is to use a phosphor material to convert monochromatic light
from a blue or UV LED to broad-spectrum white light, much in the same
way a fluorescent light bulb works.
LED Light
Red and Infrared LEDs are made with gallium arsenide.
Bright Blue is made with Gan – gallium nitride.
White LEDs are made with yttrium aluminium garnet
There are also orange, green, blue, violet, purple, ultraviolet LEDs.

LED Lighting
LEDs are just tiny light bulbs that fit
easily into an electrical circuit. But
unlike ordinary incandescent bulbs,
the don’t have a filaments that will
burn out, and they don’t get
especially hot. They are illuminated
solely by the movement of electrons
in a semiconductor material, and
they last just as long as a standard
transistor. The life span of an LED
surpasses the short life of an
incandescent bulb by thousands of
hours.
