DOI: https://doi.org/10.3365/KJMM.2018.56.3.227

Abstract
To ensure the reliability of high-power light-emitting diode (LED) bulbs, temperature management is very important, including reduction of the junction temperature on the LED chip and enhancing outward thermal dissipation. Simulation can be an effective tool for predicting the temperature distribution over all bulbs, which enables a quantitative analysis. In..... More
