Color digital laser and light-emitting diode printers are very similar. Both can print your business documents relatively quickly by melting toner to the paper, and both use a photosensitive drum. The ...

[shakirfm] sent us this LED persistence of vision (POV) laser projector that can display dot matrix style text. The laser projector contains a rotating mirror assembly and 5 lasers. We’ve covered ...

An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

When we think about the onward march of automotive technology, headlights aren’t usually the first thing that come to mind. Engines, fuel efficiency, and the switch to electric power are all more ...

Osram is revealing laser spotlights and other stage lighting technology at Prolight+Sound 2016 in Frankfurt this week. Basing the laser-based spotlights on work done for laser-based car headlights and ...

3A Laser/LED Switch Operates Spike Free Promoted as operating extremely fast and spike-free, the iC-HG laser/LED switch provides six independent channels rated at 0.5A each that can combine freely.

In 1962, when he was 33, the scientist Nick Holonyak, Jr., created the first practical visible light-emitting diode. At GE, they called it "the magic one." Someone actually wrote that on the back—here ...

A printer that uses a laser and the electrophotographic method to print a full page at a time. The laser "paints" a charged drum with light, to which toner is applied and then transferred onto paper ...
