Lighting LED is short for Light Emitting Diode‚ which is a semiconductor lighting material. It was firstly introduced as an applicable electronic element in 1962. The early versions of LED could only emit low-intensity light‚ whereas the modern ones are proved to be able to deliver light with incredible brightness. Except for the conventional semiconductor light emitting diodes‚ there are other two advanced LED products‚ the organic light emitting diodes (OLED) and the polymer light emitting diodes
