A cool LED is a happy LED

A crucial consideration in LED design is heat transfer. When you put electricity to an LED, some of that energy is converted into light, but the rest turns into heat. As the modULe heats up, its efficacy drops.

The heat sink gets heat out of an array and into the ambient air, so its design is important. If the heat sink is too small for the LED package, it will not dissipate enough heat, which lowers the efficacy and brightness of the LED. A luminaire must be designed to handle the thermal requirements of the LED, keeping the LED cool.
