White Light Emitting Diode or White LED Light

White Light Emitting Diodes or White LEDs are the next big thing in lighting. Earlier LEDs were restricted to applications like indicators, displays or emergency lighting. But with the advent of white light emitting LEDs, they are now used in almost all lighting applications ranging from indoor to road lighting to flood lighting, in other … Read more

Working Principle of Light Emitting Diode

An LED is just like a normal p n junction diode, but with light-emitting properties. Its construction and working can be explained as follows. Working of LED Like an ordinary diode, the LED diode works when it is forward biased. In this case, the n-type semiconductor is heavily doped than the p-type forming the p-n … Read more

Solid State Light or Light Emitting Diode or LED

What is Light Emitting Diode? A Light Emitting Diode (LED) is a special type of PN junction diode. The light emitting diode is specially doped and made of a special type of semiconductor. This diode can emit light when it is in the forward biased state. Aluminum indium gallium phosphide (AlInGaP) and indium gallium nitride … Read more
