Firefly bulb watts

Electroluminescence is the phenomenon where light is emitted from a material in response to an electric current or field. This differs from incandescence, which is the emission of light due to heat; this is how conventional non-fluorescent light bulbs work. Light emitting diodes LED are actually a type of semiconductor that uses electroluminescence to generate light. First developed in by Oleg Losev, commercial LEDs have been available since the s and were commonly found as calculator displays for scientific calculators. Semiconductors are usually crystalline or amorphous solids that come in two versions: n-type and p-type. The n-type semiconductor is doped with excess electrons by adding impurities like phosphorus to a silicon matrix.
