3. COLOUR TEMPERETURE OUTDOOR/INDOOR
•Colour temperature is a characteristic visible light. In practice, Colour temperature is only meaningful of light sources that do in fact correspond some what 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 temperature in KELVINS.
•Colour temperature over 5000K are called cool Colour (bluefish white), while lower Colour temperature (2700-3000K) are called warm Colour (yellowish white through red).

4. COLOUR TEMPERETURE OUTDOOR/INDOOR
Colour temperature:
•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).

7. •Sometime called Colour rendering index, is a quantitative measure of the ability of a light source to reproduce the Colour of various objects faithfully in comparison with an ideal or natural light source.
•Colour rendering: Effect of an illuminant on the Colour appearance of objects by conscious or subconscious comparison 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 the interiors.
•Colour rendering depends on the lamp Colour spectrum, reflective property of surface and context and condition in room.
•Judgment of apparent surface Colour depends also on the expectations of an individual with normal Colour vision.

30. INCANDESCENT LAMP
What ?
Hotwire –Filament sealed in a glass jar (BULB)
How ?
Electric current pass through the wire heats it to incandescence, and the wire emits light. Use standard voltage circuit.

31. 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 2500 degrees 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.

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 long life.
LAMP EFFICIENCY = LIGHT PRODUCED (LUMENS, lm)/ELECTRICITY CONSUMED (WATTS W)
3.LIGHT OUTPUT: Insert gas (Argon, Nitrogen, Krypton) slows bulb blackening caused by condensation on the bulb wall

41. INCANDESCENT LAMP
Bulbs are sold by WATTS –Measure of power consumed
LUMENS tells 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

42. INCANDESCENT LAMP
LAMP TYPES:
1.NON DIRECTIONAL (emits light in all directions –A, C, G, P, PS, S and T shapes, requires additional external elements for brightness, glare and distribution control)
2.SEMI DIRECTIONAL (silver bowl or white bowl lamps, coating on inner side of bulb, reduce filament glare)
3.DIRECTIONAL (complete optical systems: source, reflector, lens or filament shield, R, AR, MR, PAR built-in beam control)

47. What ?
Selected gas of the halogen family
How ?
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

48. A halogen bulb has a filament of tungsten, which glows when electricity is applied, same as a regular incandescent bulb.
The halogen gas removes the carbon deposits on the side inside of the bulb, caused by the burning of the tungsten filament, and redeposits it back on to the filament, resulting in a bulb which can be burned at a higher
TUNGSTEN -HALOGEN

49. TUNGSTEN -HALOGEN
High operating temperature (500C), high Colour temperature
Quartz instead of glass
Equipped with outer bulb, glass cover, mesh screen

50. TUNGSTEN -HALOGEN
Advantages
1.High Colour temperature make them “whiter” than standard incandescent lamps
2.Longer life time
3.Great efficiency
4.Compact in shape and size
They come in many shapes and sizes, some directional others note, some quite small other the size of regular bulb, some fit into normal sockets other require special sockets and voltage to work.

51. TUNGSTEN -HALOGEN
There are many different type of (single ended) TH lamp, the most common ones are the G9 capsule lamp, GU10 spot lamp and linear halogen lamps which are all domestic mains voltage, and g4 capsule lamp, (integral reflector) MR16, MR11 spot lamps which are low voltage lamps.

53. 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 luminaries with integrated transformers are larger in size and bulkier.
•Practical system is line-voltage equipment.

55. COLOUR LIGHT BULBS

56. COLOURED FILTERS

57. GELATIN FILTERS (“GELS”)
Thin transparent colored plastic sheet in vide variety of Colour, as well as multicolored and diffused sheets. Short servise life –Colour fades rapidly.

58. INTERFERENCE FILTERS
One or more layers of ultrathin film coating on clear glass that reflects rather then absorb unwanted wavelength. They transmit one Colour, and reflect the complementary Colour.

59. What ?
Gas, phosphor, cathode, discharge
How ?
Light is produced by passage of an electric current through a vapor of gas, rather than through a tungsten wire as in incandescent lamp.

60. FLOROSCENT LAMP

61. FLOURESCENT 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 electrode to make a connection. This arc lights the bulb in the same way a larger arc lights a fluorescent bulb.
