Nick Holonyak Jr. had one of those bright ideas that lit up the world. In 1962, he invented the first practical red light-emitting diode (LED).

How do fluorescent lamps produce light?
LED means light emitting diode. Diode is an electronic component which has two nodes. when power supply is given between two nodes the current flows and emits light from it which is in visible spectrum. Hence light appears from LED lamp. As the energy required for emitting light is very less hence LED lights give very high lumens per watt
What does a bi-colour light emitting diode do?
There are actually two different LEDs of different color inside one package, wired so that either one or the other can light depending on how power is applied to the leads. Some bi-color LEDs will also permit both to light at the same time.
What is most energy efficient led lamps or bulbs?
The most efficient outdoor light bulb would the 5 watt Light emitting Diode light bulb also know as the LED bulb. They are small lights with miniature sockets or made to fit into conventional sockets.
What part of speech is incandescent?
Adjective ( emitting light, usually as a result of being heated)
What light bulbs produce little infrared?
Essentially, any bulb will produce some infrared, which is most easily detected as heat. The lowest infrared emitter is GENERALLY the Light Emitting Diode or (LED), followed fairly closely by the Compact Fluorescent (or CFL). I say Generally, because an LED can be manufactured to emit any frequency, and there are infrared LEDs, but these are low power and most often used in remote controls.
Who invented the led light bulb?
"Nick Holonyak, 75, invented the LED (light emitting diode) in the 1960s."
What does LED stand for in LED lights?
Light Emitting Diode - LED
What is an L.E.D?

Is Light Emitting Diode conduct in both direction?
A light emitting diode does not conduct in both directions.
Which is better light emitting diode or laser diode?
Laser diode
