What is a LED?
 LED - Light Emitting
Diode
 A semiconductor
component similar to
transistor or integrated
circuit
 Electrical current through
the semiconductor chip
produces light
 Semiconductor materials
used, define the colour of
light produced

Benefits of LEDs
 Extremely reliable: MTBF
(Mean Time Between
Failures) is millions of
hours
 Very long lifetime: light
output degrades 25-30
% after 11 years of
continuous operation
 High luminous efficiency:
30 lumen/watt of LED
light compared to 5
lumen/watt of white light
with red filter
