Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

The driving force behind the switch from incandescent lighting to LED technology is to gain power efficiency and longer life. However, the cost of LED assemblies is much higher than incandescent and ...

Part 2: A 60V buck-boost controller drives high power LEDs, charges batteries and regulates voltage with up to 98.5% efficiency at 100W and higher. Part 3: Offline LED lighting simplified: A high ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

Time will always be“of the essence” for professional engineers and amateur enthusiasts alike. This can certainly be said about the process of designing circuits involving Light Emitting Diodes (LEDs).

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 ...
