A large percentage of LED drivers offered by many vendors use PWM (pulse-width modulation) intensity control to adjust LED brightness for a wide range of applications. In the PWM drivers, the ...

LEDs are durable and save energy. Now researchers have found a way to make LED lamps even more compact while supplying more light than commercially available models. The key to success: transistors ...

Gallium-nitride (GaN) transistors enable the compact design of LED lamps that provide more light for less energy. Despite their advantages as light sources—they consume less energy, use no harmful ...

Demand for LEDs continues to grow across industries — indoor/outdoor lighting, display sectors, and automotive lighting — thanks to their higher energy efficiency, lower heat output, and ...

CCFL backlights are the most common backlight technology and are used in displays ranging from 5.7 to 23 in. or more diagonal. They can have from one to 24 or more lamps mounted along the edge of the ...
