The description of LED light (lamp)?
LED is abbreviation of Light Emitting Diode, it is a new technology developed the middle of the 20th century. It is direct light relies on the electrons of semiconductor heterojunction removed by barrier energy. The light produced by LED is luminescence process which does not generate heat, the energy conversion efficiency is close to one hundred percent, long service life, and the LED light is the continuous development of lighting technology direction.
LED fine low energy street lamps principle:
Light-emitting diodes (led) core part is composed of p-type and n-type semiconductor chips, between the p-type and n-type semiconductor has a transition layer, called the p-n junction. In some of the semiconductor PN junction, the minority carrier injection compound with majority carrier will release excess energy in the form of light, so as to directly convert the electric energy to light energy. PN junction to add reverse voltage, and minority carrier injection, so don't shine.
