Light emitting diode applications

The principle operation of LASER diodes is based on stimulated emission, whereas LED is based on spontaneous emission. The most common eminent source . With their good energy efficiency and characteristics that allow the adjustment of light intensity and spectral composition, light emitting diodes (LEDs) have opened up new research prospects for nutrition supply, pollution control as well as energy conversion and conservation. The potentials of LED as an effective light . Light Emitting Diode lamps have become highly popular and as the energy consumption is very low for them, they are also being made by LED s.

Advances in plant tissue culture methods with regard to lighting requirements are currently focused on the improved features of light - emitting diodes (LEDs).

Over the years, the steady development of LED technology, with the emergence of new types of semi-conductor materials, has made it possible to apply it in an .

This means that an LED will pass current in its forward direction but block the flow of current in the reverse direction. They can also be bought in forms that will switch between two colours (bi-colour), three . Light - emitting diodes (LEDs) possess unique properties that are highly suitable for several operations in the food industry. A light Emitting Diode (LED) is an optical semiconductor device that emits light when voltage is applied. In this respect, the LED or IRED resembles most other diode types, but there are important differences. Applications of Light Emitting Diodes in Health Care.
