This video explains how LEDs (Light Emitting Diodes) function and why they are widely used in modern lighting and electronic ...

I’m something of a headlight nerd. In a previous life, I retrofitted HID projector headlamps onto my 2009 Honda Civic Si for better light output. I’m planning a similar project for my beater 2015 VW ...

Light emitting diode printers are usually classed with laser printers because they use a similar method of creating pages. Like a laser printer, they use a drum, toner and a fuser, and provide crisp ...

The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...

The function of an LED is to emit light when the device is forward biased within its operating range, and it’s known by most ...

A thirteen-year-long mystery that has involved a long series of researchers has finally been solved. A new article presents a diode in printed electronics that works in the GHz band, which opens up a ...

That means inside every LED bulb are tiny circuit components -- and their soldered contact points -- which are far more vulnerable than the diode itself. The Lighting Research Center of the Rensselaer ...
