Exar's patented AC step driving ICs provide industry-leading solutions for bulb, tube and downlight applications that do not require the use of inductors, transformers, electrolytic capacitors or ...

The numbers you see on the box don't always work out in real life. LED bulbs do last longer, but those claims about five to 10 years are estimates based on internal testing -- and companies are always ...

That means inside every LED bulb are tiny circuit components -- and their soldered contact points -- which are far more vulnerable than the diode itself. The Lighting Research Center of the Rensselaer ...

LED bulbs use DC power, which requires a converter and drivers to switch from standard AC power in homes. That means inside every LED bulb are tiny circuit components -- and their soldered contact ...

Aachen, Germany – Scientists from Philips Research have developed the first-ever organic light emitting diode (OLED) module that can be powered directly from a mains electricity supply. The prototype ...

This ultra-bright white LED lamp works on 230V AC with minimal power consumption. It can be used to illuminate VU meters, SWR meters, etc. Ultra-bright LEDs available in the market cost Rs 8 to 15.

Power Integrations has introduced a one-chip non-isolated LED driver for loads up to 22W. Capable of working from inputs from 90 to 305Vac, it is triac (and trailing-edge) dimmable on nominal 110V ...

The Biden administration is scrapping old-fashioned incandescent light bulbs, speeding an ongoing trend toward more efficient lighting that officials say will save households, schools and businesses ...

LED bulbs convert more energy into light instead of heat compared to older light bulbs. This is what makes them more efficient and it’s why they use less electricity. Switching to all LED bulbs can ...
