INTRODUCTION

• Lighting is an essential service in all the industries.

•  The power consumption b the industrial lightingvaries between ! to "#$ o% the total powerdepending on the tpe o% industr.

• Innovation and continuous improvement in the &eldo% lighting' has given rise to tremendous energsaving opportunities in this area.

•  provides a ma(or scope to achieve energ e)cienc

at the design stage'•  * incorporation o% modern energ e)cient lamps'

luminaries and gears' apart %rom good operationalpractices.

Luminaire is a device that distributes'&lters 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

Latest technolog

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.
