How to measure thermal resistance of LED emitters and arrays Part 2
The process used to determine thermal resistance values from the LED junction-to-case and LED junction to Ts reference point. Part 1 of this article discusses measuring junction-to-case thermal resistance; determining the K-factor and testing Rth J-C (see Vector, March 2019, page 25). Thermal performance is the most critical aspect of a well-designed LED lighting system. […]
