LED - Why Such Interest?
With the first generation of thin-film LED……in 2001 OSRAM pioneered thin-film technology. This technology – which makes almost all the light generated in the chip available for use – has given rise to such innovative products as OSTAR® Projection. The new high-flux LED from OSRAM are powerful enough to be used in mini projectors

What is an LED ?
A light emitting diode (LED) is a solid state electronic component
An LED produces light by injection luminescence
Individual LED’s are referred to as discrete
Discrete LED’s are mounted on a printed circuit board PCB for use
LED assemblies for lighting are referred to as LED modules

What are the advantages of LEDs?
Safe low voltage operation A single LED will operate on no more than 3.5V OSRAM LED modules operate at either 10 or 24V
Design cost reductions Fit and forget installation Relaxation of localised heating considerations Certain safety systems are not required
Cost effective solution
Offers new possibilities Compact luminaires More flexible solutions Full colour mixing possible
