LED consists of a chip of semiconducting material impregnated, or doped with impurities to create a p-n, (positive / negative) junction. *�l>q��+9�kW2�w����q�`�����1ߓqw$F���dG#�H3��� Today’s LEDs are available in many different types, shapes, and sizes, a direct result of the tremendous improvements we’ve seen in semiconductor technology over recent years. Let us know what kind of LEDs you are using for your applications at [email protected].
While these are the most efficient bulbs to date, they are not without problems. Tri-colour LEDs This type of LED has three leads enabling any combination of LEDs to be light, i.e.
Download the PDF here With greater advances in the technology, you can now get a range of styles including candles, GLS, golf balls, reflectors, spotlights and tubes. A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. An article about Basics of LED, Characteristics of LED and different Types of LED.

1U3>9�B�����'�! BY JEFFREY BAUSCH. In the recent past, LED lighting used to be fairly limited with few designs to choose from.
Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor.

They also are the latest lighting technology with respect to integrating with smart lighting tech. LEDs that produce white light work in a rather complicated way, and their invention won a Nobel Prize in Physics in 2014!
