In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED lighting’s many advantages simply cannot make up ...

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 ...

Consumer demand and government initiatives to phase out inefficient lighting technologies are pushing expansion of LED lighting. Designers of these devices must satisfy not only end users, but also ...

When a lighting application requires a custom array of LEDs, a flyback ac-dc driver can be developed quickly and economically, while providing power-factor correction and dimmability. LED replacement ...

When Raj Patel looks down from an airplane, he doesn't see streetlamps dotting the ground. He sees potential business partners. Patel founded Ferndale-based Midwest Circuits, now a municipal LED ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

ANSAN, South Korea--(BUSINESS WIRE)--Seoul Semiconductor, a leading global innovator of LED products and technology, has developed the industry’s smallest 100V / 24W LED driver for Japan lighting ...
