Electroluminescence is the direct conversion of
electricity to light.
Electroluminescence is cool light, unlike incandescent lamps
where light is generated by heating a filament to high
The heat from the lamps barely increase by 1
Solid state lighting.
Unlike incandescent lighting there is no filament and therefore
no critical failure.
Light output decays with age.
EL lamps are probably the most rugged lighting technology
A promising future
Thanks to recent advances in electronics and materials
chemistry, EL lamps have re-emerged as an innovative and
exciting lighting technique.
