Measurement basics in LED thermal management
A successful LED design needs a balance of form and function to be a desirable luminaire with the right lumen output. Sounds simple enough, but these two requirements are often in conflict. When form trumps function, LEDs that are usually mounted onto a
metal-clad PCB (MCPCB) as a module are all too often crammed together,
creating a module with high-power density. If the device has not been
designed to remove the heat from the LEDs effectively, there is a real
risk of the LED overheating. As with any semiconductor, when LEDs
overheat efficiency is reduced, light quality deteriorates, lifespan
shortens and ultimately the LED can catastrophically fail.
