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.
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).
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
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.
Adjective ( emitting light, usually as a result of being heated)
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.
