Editors’ Note: This segment is adapted from Chapter 3 of Power Supplies for LED Driving by Steve Winder. We have seen in Chapter 2 that an LED behaves like a constant voltage load with low equivalent ...

Solid state lighting solutions are increasing in popularity across a broad variety of illumination, indication, signage and backlighting applications, replacing traditional incandescent and ...

Semiconductor junctions — from the millions of transistors used in ICs to the large-area compound junctions that make high-brightness LEDs possible — can all suffer early failure due to increased heat ...

This file type includes high-resolution graphics and schematics when applicable. Many applications for LED illumination require wide dimming ratios, which can be easily done using an adjustable ...
