This device uses an external low side N-channel MOSFET and can drive up to 90V of white LEDs from a nominal 12V input, delivering in excess of 50 watts. Spread spectrum frequency modulation reduces ...
Semiconductor lighting technology is developing rapidly. While seeking high luminous efficiency, low cost, and superior reliability, researchers are increasingly focusing on the effects of LED ...
A typical LCD consists of liquid crystal material with transparent electrodes and polarizing filters. Applying voltage across the liquid crystal layer allows light to pass through in varying amounts.
