Company says it has demonstrated the production of LED light chips on silicon, an effort that could ultimately result in cheaper energy-efficient light fixtures. Martin LaMonica is a senior writer ...

LED Chips, on the Cheap LED bulbs have long been lauded as an energy-efficient alternative to incandescent bulbs. But LED, or light-emitting diode, bulbs are expensive to produce, which has kept ...

Researchers have designed and tested ‘human-centric’ LEDs that emit different wavelengths of blue light depending on whether it’s daytime or nighttime, reducing the disruptive effect artificial light ...

Researchers at OSRAM Opto Semiconductors have succeeded in manufacturing high-performance blue and white LED prototypes in which the light-emitting gallium-nitride layers are grown on silicon wafers ...

Researchers at The University of Osaka, in collaboration with ULVAC, Inc. and Ritsumeikan University, have developed a new ...

Scientists have been working for years to harvest the power of ambient radio waves to power small devices, and these days there is hardly a richer source of these signals than Wi-Fi networks.

LED technology has come a long way in the last five years, and in 2020 there are a bunch of brands selling well-made, well-engineered LED replacements for your car's old halogen headlight bulbs.

To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been ...
