Semiconductor lighting, namely Light-emitting diode (LED for short), is a kind of semiconductor solid-state light-emitting device. The principle of its luminescence is to use solid-state semiconductor chips as luminescent materials. In the semiconductor, the excess energy is released through the recombination of carriers, causing photon emission and directly emitting red, yellow, blue, green, cyan, orange, purple and white light.

Application fields: street lighting, architectural landscape lighting, plant lighting, automotive lighting, etc

Common LED packaging types: SMD, high-power LED

Common materials: 2835, 5630, 3030, 5050, 5730, 3528, 3014, 4014, 7030, 2121, 3535, 1W high power, 3W high power, 5W high power, etc
