Luminaire is a device that distributes'<ers or trans%orms the light emitted%rom one or more lamps.
The luminaire includes' all the parts
necessar %or &5ing and protecting thelamps' e5cept the lamps themselves.
The basic phsical principles used in
optical luminaire are re,ection'absorption' transmission andre%raction.

Some Basic Facts About White LEDs
It can be placed in abusive environments
It can be "AC" or "DC" powered depending on the model It is the newest lighting device on the mar!et toda
It do not produce "#F" to inter$ere with radio e%uipment
It is a proven technolog
It last about &''( ''' hours o$ continuous use
It radiate light at a &) to *) degree angle depending on the model
It can be made completel waterproo$ $or use in man marine applications
It polarit protected( so it is hard to ma!e an installation mista!e
Luminosity:
White LEDs, typically 20 to 60 Lumens/Watt orbetween 5000 & 12000 mille canles

Jrganic light9emitting diodes 0JLECs1 represent anotheremerging technolog that is still in the laborator.
I% it can be made practical' it ma ma3e even more o% adramatic impact on how spaces are lighted than LECs.
In %act' it ma one da replacing LECs as an energ9e)cient alternative %or general lighting.
JLECs are similar to electroluminescent lighting' in which asheet o% material is e5cited so that it emits light.
7n JLEC light source is a thin' ,e5ible sheet o% materialconsisting o% three laers' a polmer or sublimed molecular&lm sandwiched between two laers o% electrodes' one o%them transparent.
urrent passes through the material until it emits lightthrough its transparent laer.
