If you are looking to replace halogen bulbs with LEDs, combining a rectifier bridge and a current-controlled synchronous step-up/step-down converter creates a high power factor driver circuit, writes ...

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 ...

Designers of early indoor LED light bulbs faced numerous technical hurdles, including AC-to-DC conversion, thermal heat-sinking, constraints imposed by current bulb sizes, electrical transients, and ...

Soraa, the Khosla Ventures-backed startup that uses the semiconductor gallium nitride rather than sapphire in its LED and laser technology, came out of stealth mode Tuesday and unveiled its flagship ...

Yes yes, as some may know, I shouldn't even be thinking about electricity. However, I am fairly comfortable with 12v transformers for halogen light bulbs and swapping them out if they go wonky. So I ...

Upgrading your headlights is one of the easiest, cheapest, and simplest mods. It’s often the first mod of any prospective car modder, or it could be just time to swap out some old bulbs. Either way, ...

This halogen light switch circuit works only for dc halogen lamps. Halogen lamps give a good light and have an excellent eficiency. In this halogen switch circuit we use a FET transistor because the ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...
