High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.

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 ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

Lighting fixtures that cover wide areas, such as streetlights, often use LED matrices comprising strings of HB LEDs (high-brightness light-emitting diodes) that rely on off-the-shelf constant-current, ...
