LED, the full name of semiconductor light-emitting diode, is made of semiconductor materials to directly convert electrical energy into light energy and signals into light-emitting devices; it is characterized by low power consumption, high brightness, bright colors, anti-vibration, long life (normal light emitting 8-100000 hours), cold light source and other advantages, is the real “green lighting”. The lighting products with LED as the light source will inevitably replace the white woven lamp and become another revolution of human lighting in the future of the 21st century.
