A novel automated heat-pipe cooling device for high-power LEDs
1. Overview: 2. Research Background: High-power LEDs are increasingly popular in various applications, offering advantages like long lifespan, high reliability, low energy consumption, fast response time, and color variability. However, their efficiency (15-25% power-to-light conversion) is limited, with over 80% of power dissipated as heat, leading to high junction temperatures. Maintaining junction temperatures below 120°C
