If you thought mousetraps were tough, try building a better lightbulb. Just in time for Earth Day, a team of American inventors have created a bizarre-looking new bulb that turns illumination on its ...

The idea is that by using smaller red, blue, and green LEDs, Micro RGB TVs will not only have better color accuracy, they’ll ...

Cree's latest LED light source slices the cost, but it's betting that features such as better controls and long life give LEDs an edge over other technologies. Martin LaMonica is a senior writer ...

Better materials promise LEDs at a fraction of the cost, say researchers. Apart from their use in more economical and efficient illumination, these better materials could be useful also in power ...

LED lighting has long been viewed as a superior alternative to compact flourescent bulbs. Although flourescents are more electrically efficient than old-fashioned incandescent bulbs, producing them ...

When LEDs were first introduced, it was hard for us to part with our old friends incandescent and halogen lamps, and the luminaires made for them. It seemed like nothing could ever replace the warm ...

Princeton University researchers have developed a new method to increase the brightness, efficiency and clarity of LEDs, which are widely used on smartphones and portable electronics as well as ...

While regular Hackaday readers already know how to blink a LED with a microcontroller and have moved onto slightly more challenging projects such as solving the Navier-Stokes equations in 6502 ...

As Light Emitting Diode (LED) technology improves, Original Equipment Manufactureres (OEMs) and operators are upping their use of the “smart” lighting throughout the aircraft — inside and out. Already ...

Before you decide whether to replace bulbs or replace components, it’s important to know what to be looking for. These points I’ve mentioned before, but I think it’s very important to repeat them.

Of the 90% of Americans who have used LED or CFL light bulbs to save energy and cut costs, most use CFLs, according to a Consumer Reports study released Thursday. Almost 75% of consumers who have ...

Using a new nanoscale structure, electrical engineers have increased the brightness and efficiency of LEDs made of organic materials -- flexible carbon-based sheets -- by 57 percent. The researchers ...
