LED thermal characteristics - LED junction temperature and thermal resistance

LED thermal characteristics mainly include the LED junction temperature, thermal resistance (transient thermal resistance, steady state thermal resistance), the transient change curve (curve of heating and cooling curve), refers to the LED junction temperature of PN junction temperature, thermal resistance refers to the temperature difference LED cooling channels with the channel on the ratio of the dissipation power, used for characterization of the LED heat dissipation capacity.The lower the thermal resistance of LED, the better the heat dissipation performance, the higher the corresponding LED light effect, the longer the life expectancy.

Testing LED thermal properties is the key to accurate measurement of the LED junction temperature, generally there are two ways: one is to use the infrared temperature measurement method to measure surface temperature of the LED chip and regard it as the LED junction temperature, but the accuracy is not enough;The other is to obtain PN junction temperature by temperature sensitive parameter (TSP), which is the most common LED temperature test method at present.
