Light Emitting Diodes exploit the property of the p-n junction to emit photons when it is forward biased. LEDs are specially made diodes to emit light when a potential is applied to its anode and ...

With LED headlights becoming the prevailing form of automotive lighting, here’s a good breakdown and how it all works.

Discover the science behind diodes — the tiny components that control the flow of electricity. Learn how they let current pass in one direction, block it in the other, and power everything from ...

LED lights are the latest thing in home lighting, using less energy and lasting longer than their incandescent cousins. How do they work? Find out in the latest installment of Appliance Science.

What are LED Matrix lights and how do they work? In mathematics, a matrix is defined as a rectangular array of numbers organised in rows and columns which are treated as a single entity.

How Does an LED Printer Work?. 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 ...

How it Works? The most common laser diode generates semiconductor or injection laser. In these lasers, a population of Inversion Electrons is produced by applying a voltage across its p-n junction.

If you've been researching beauty treatments online lately, it's possible you've seen ads for LED (light-emitting diode) masks in your social media feeds. The masks are designed to do several ...
