Green LED is bright enough for large projector

Osram Opto Semiconductors has developed an extremely bright, green light-emitting diode (LED) that makes LED projectors in office environments possible. Projectors in conference rooms have to be very bright for viewers to ...

Review: Three ways to control your lights at home or away

Home automation seems to be one of those tech industry snowballs that's starting to roll downhill. The 2015 Consumer Electronics Show was packed with new ways to control your home environment.

Faster LEDs for wireless communications from invisible light

Researchers have solved a major problem for optical wireless communications—the process by which light carries information between cell phones and other devices. Light-emitting diodes (LEDs) pulse their light in a coded ...

Voiding defects: New technique makes LED lighting more efficient

Light-emitting diodes (LEDs) are an increasingly popular technology for use in energy-efficient lighting. Researchers from North Carolina State University have now developed a new technique that reduces defects in the gallium ...

Asymmetry is key to creating more stable blue perovskite LEDs

Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have developed blue LEDs based on a material called metal halide perovskite, that, for the first time, uses asymmetrical bridges ...
