An LED driver composed of a boost converter and dimmable current regulators with adaptive voltage feedback control (AVFC) is proposed. The AVFC is fulfilled with two diodes, one integrator, and one ...

If you can screw in a lightbulb, you can install the Lorex 2K Wi-Fi Lightbulb Camera that combines an LED light source with a ...

In this paper, a dimming control approach is proposed for visible light communication based on layered asymmetrically clipped optical orthogonal frequency-division multiplexing (LACO-OFDM) to satisfy ...

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

Chinese scientists have discovered a new LED technology, potentially revolutionizing electronic devices by enhancing their energy efficiency, brightness and affordability.

For most people, LED masks are safe, but you’ll want to talk to a dermatologist first if you have an existing skin condition. These light therapy devices have the potential to smooth wrinkles ...
