This is the simple version of a white LED lamp that can be directly powered from mains. It can give ample light even for reading purpose. Capacitor Cx along with diodes D1 through D4 forms the AC step ...

The iML8684 claims improved circuit stability in sub 3Vac situations created by TRIAC dimming, resulting in superior light quality at low dimming. This improvement also increases the number of ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

True to the history of other types of semiconductor products, LEDs offer better performance at a lower cost with every passing year. So much so, in fact, that the other elements of a conventional LED ...

Edison Opto is the first manufacturer to launch chip-on-board (COB) based AC LED modules, releasing the 7W omnidirectional AC COB module, EdWing Series, and the high efficacy driver on board module, ...

High-brightness LEDs are an inexpensive, robust, and green replacement for halogen light bulbs. This Idea for Design shows you how to apply an AC LED driver to convert the usual 12 or 24 V AC ...
