LED Thermally-Related Premature Failure
How Lighting Innovations, Inc. LED Avoids this Dilemma
Despite an efficiency advantage over other light sources, LEDs can still suffer reliability issues if all parts of the lighting system, including the driver, aren’t properly protected from over-temperature moisture situations, says Steve Roberts. (Technical Manager)
LEDs are substantially more efficient than halogen or incandescent lighting and yet they will still fail prematurely if not thermally protected. It seems counter intuitive to have a more efficient solid state light that needs more heat-sinking than an inefficient traditional light. A robust thermal system design must account for all elements of the lighting system including the driver. (Note that watts are the radiometric units of radiant flux while the more commonly given LED specification of lumens are photometric units of luminous flux.) The lower the temperature of the connection point of the LED to the circuit board, the brighter the lumen output of the LED and the longer rated life
