Unmasking LED Behaviors: The Crucial Interplay of Heat and Light Performance

For LED technology, from the LED chip to related products such as LED lamps, modules and fixtures, high operating temperature can result in mechanical failure and significant drop of performance.

How a LED behaves when subjected to higher operating temperatures is directly related to its quality. High quality LEDs (such as Nichia or Cree) will function within parameters at high temperatures too, while low quality LEDs will break down, change their color, loose brightness or a combination of these.

For LED technology, we need to avoid operating at temperatures beyond those specified by the manufacturer. Failure to do so while lead to at least one of the following:

complete failure of the LED
light output is decreased permanently (Lumen Degradation) even if the issue with high temperature is solved
light output is decreased temporally while the LED functions at high temperature
the color temperature of the white LED changes

Understanding and Optimizing Heat Management in LED Lighting Systems

Getting the most from a product based on LED technology can be tricky because of one important factor: how operating temperature can result in a substantial difference between the advertised and actual performance of a LED based product.

Important factors in this effect are the LED quality, product design and heat management: how much of the heat generated while in operation is channeled away.

If the heat is well managed, a LED based lighting product will have performance as advertised, long life and will be energy efficient.

The basics of LED heat management

LEDs use electricity and this process generates heat. This heat needs to be channeled away from the LED in the ambient as efficient as possible. Designing the LED itself and the luminaire for this purpose is called heat management. The heat that needs to be channeled away is directly proportional with the luminous flux and power consumption of the LED.
