LED

The English name of LED is light emitting diode (light emitting diode) abbreviation, and 120V LED basic structure is an electroluminescent semiconductor materials, placed on a wire rack, then sealed with epoxy resin around, protect the internal core wire effect, so the seismic performance of the LED. First, the structure and the LED light-emitting principle 50 years ago, people already know the basics of semiconductor materials can produce light,G4 LED the first commercial diode produced in 1960. LED is the English light emitting diode (light emitting diode) abbreviation, and its basic structure is an electroluminescent semiconductor materials,12V LED placed on a wire rack, then sealed with epoxy resin around, protect the internal core wire effect, so the seismic performance of the LED. The 3W LED core of the light-emitting diode chip is a p-type semiconductor and n-type semiconductor in the p-type semiconductor between the n-type semiconductor, and a transition layer, called the p-n junction. In some semiconductor materials, PN junction, the injected minority carrier and majority carrier recombination, when will the excess energy released in the form of light, which converts electrical energy directly into light. PN junction reverse voltage, minority carrier injection is difficult, it is not light. This use of injection electroluminescent diodes called the principle of making light-emitting diodes, known as LED. When G4 LED 1W 110-150lm
 is in working condition (ie, ends with a positive voltage), current from the LED anode to the cathode, the semiconductor crystals from the ultraviolet to the infrared light of different colors, light intensity and current.
