LED profile within Volume 1234, LED, lamp, SMD process introduction, process introduction, instrument introduction, LED electrical parameters, electrical parameters Precautions for use in 55 LED How does the work principle of LED work? The LED light emitting diode, is Light Emitting Diode English -, to emit the natural light emitting diode, the English is abbreviated, light emitting diode English - ultraviolet, visible and infrared light wavelength junction. Ultraviolet light, visible light and infrared light wavelength of the P/N junction. The luminescence principle is El, according to the surface of the light-emitting principle is electro luminescence, semiconductor junction (P/N Junction) after orthodromic conduction, the free valence electron and hole coupling with forward current conduction after the semiconductor junction forward current conduction after, and will be transformed into electrical energy visible radiation LED advantages Long life, generally greater than 10000 hours long life, generally more than 100 thousand hours of low power consumption, high brightness, low power consumption, high brightness, and integrated circuit, small volume, light weight, small volume, light weight, can be packaged into various types of displays are durable, durable, resistant to shock the multicolor display. Multicolor display, can achieve color display temperaturestability fast response time, generally nanosecond fast response time, generally ns (NS) level of cold, cold, not hot light source when combined with photoelectric crystal can be used as low noise optical switch when combined with photoelectric crystal can be used as low noise optical switch low voltage you can use solar battery as power supply, and easy and integrated circuit to match the voltage is low, can
