LED and its characteristics
LED (Emitting Diode Light), which is a light-emitting diode, is a kind of semiconductor solid light emitting device. It has neither a burning filament nor an ionized gas, so the temperature at which it works is also very low. Since the birth of Blu ray LED, the development of LED by leaps and bounds. Because blue light can excite the phosphor to produce white light. Currently on the market of white LED are such a production.
LED has the following special advantages when used in lighting:
The luminous efficiency of LED. Currently available to the procurement of LED luminous efficiency has reached 100 LM / W, its luminous efficiency is much higher than the energy-saving lamps, metal halide lamp and electrodeless lamp, than the widely used in the street lamp high pressure sodium lamp also higher than 10%. Therefore, LED has now become one of the most luminous efficiency of the light source. Using led to replace the incandescent lamp, fluorescent lamp, metal halide lamp and high pressure sodium lamp, such as light source is no longer a big technical obstacles, just a matter of time.
