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
