Solid-state lighting (SSL) differs from conventional lighting in that it uses light-emitting diodes (LEDs) instead of filaments, plasma, or gases. Although still relatively early in its development, ...

To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller.

Samsung sent me one of their new LED sno-cone-type bulbs to try out. The bulb specs are: 550 lumens at 10Wat a color temperature of 3000K, and comes with a 5-year warranty. Its list price is $19.98.

If you agree with our assertion that smart light switches are a better solution than smart light bulbs, you should give Cree’s new A19 soft-white dimmable LED a long look. Far too many LED bulbs choke ...

With the advancement of new materials and manufacturing processes, a new lighting source, high brightness LEDs are now attracting increasing attention from academia and industry. LEDs are both ...

The LED, or light-emitting diode, itself is very unlikely to fail, and if it does, it goes out slowly over the years. Instead, it's the other electrical bits in LED bulbs that fail and cut off the ...

An LED driver IC for automotive applications must meet many requirements. It must be flexible, implementing multiple functions like high beam, low beam, fog lights, daytime running lights (DRLs), ...
