High power light-emitting diodes (LEDs) can use 350 milliwatts or more in a single LED. Most of the electricity in an LED becomes heat rather than light (about 70% heat and 30% light).[1] If this heat is not removed, the LEDs run at high temperatures, which not only lowers their efficiency, but also makes the LED less reliable. Thus, thermal

High-brightness LED drivers are integrated circuits that are optimized to efficiently drive strings of high-brightness LEDs. Maxim's continually expanding portfolio includes products covering the full range of efficient switch-mode topologies (step-down, step-up, SEPIC) as well as some linear LED

Higher ambient temperature leads to higher junction temperatures, which can increase the degradation rate of the LED junction element, LED will gradually lose its brightness over time so LED bulbs don’t go out completely they just get a little dimmer every ...
