Each LED's thermal resistance is defined by either RthJS elec, RthJS real, or both. Both essentially represent the thermal resistance between the junction temperature TJ and the solder point temperature TS, but they differ in how they account for the energy from the light output, so care must be taken when using them.
■RthJS elec: This is the thermal resistance value at a certain luminous efficiency of the LED. (The specified luminous efficiency is listed in the datasheet.) It can be used for simple heat generation calculations.
TJ = input power × RthJS elec + TS
■RthJS real: This thermal resistance is based on the actual power loss converted into heat, calculated by subtracting the energy radiated to the outside as light from the electrical input power. While calculations require subtracting the light energy, it allows for accurate heat generation calculations.
TJ = (Input Power - Light Energy) × RthJS real + TS
We have also explained the heat generated by LEDs in our technical column, so please check it out.
