LED lamp is an electroluminescent semiconductor material chip. It is solidified on the bracket with silver glue or white glue, and then connected with the chip and circuit board with silver or gold wire. It is sealed with epoxy resin around, which protects the inner core wire. Finally, Snowing Musical LED Lantern Prelit Christmas Decoration the shell is installed, so the anti-seismic performance of the LED lamp is good. Light-emitting diode (LED) is a kind of solid-state semiconductor device which can convert electric energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor wafer. One end of the wafer is attached to a bracket, the other end is connected with the positive pole of the power supply, so that the whole wafer is encapsulated by epoxy resin.
Semiconductor wafers consist of two parts, one is P-type semiconductor, in which holes dominate, and the other is N-type semiconductor, in which electrons dominate. But when the two semiconductors are connected, a P-N junction is formed between them. When the current acts on the chip through the wire, the electrons are pushed to the P region, Snowing Musical LED Lantern Prelit Christmas Decoration where the electrons recombine with the holes and then emit energy in the form of photons, Snowing Musical LED Lantern Prelit Christmas Decorationwhich is the principle of LED lamp luminescence. The wavelength of light, the color of light, is determined by the material that forms the P-N junction.
LED uses cold light source, small glare, no radiation, no harmful substances in use. The working voltage of LED is low. It uses DC drive mode, ultra-low power consumption (0.03~0.06W single transistor), and the electro-optic power conversion is close to 100%. Under the same lighting effect, Snowing Musical LED Lantern Prelit Christmas Decoration it can save more than 80% energy than the traditional light source. LED has better environmental benefits, no ultraviolet and infrared rays in the spectrum, and the waste can be recycled, no pollution, no mercury element, can be safely touched, belongs to the typical green lighting source.
