LED lamps
are light emitting semiconductor, Thermal reliability of the
semiconductor will have a bad,
For example, to power the LED-10W. The current situation, only 2W of
power into light, 8W power will be converted into thermal energy.
LED will emit a large amount of actual heat, Hot on the LED will
produce light attenuation, Failure to. Therefore, cooling of the LED is
very important.
LED lights use the car to take into account the temperature of the
environment of space, If installed in the car before the headlights
(halogen) together with the temperature of the engine, This ambient
temperature above 80 degrees, LED will quickly decay.
CHI MING ELECTRONICS CORP. By a long-term research and development. The
development of LED over-temperature protection device. Can use the
ambient temperature above 80 degrees C.
Although the LED is only 20% into light, but still far more than
light-emitting efficiency of incandescent filament. LED heat to
overcome the problem of, Is now the most efficient LED light source.
