LED street lamps and conventional high-pressure sodium lamp street difference is that high-power LED street lamp with low-voltage DC power supply by the GaN-based power
High-power LED street lighting
Blue LED and yellow phosphor synthesis of high efficiency white light diodes, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in urban road lighting. Housing available PC tube production, high temperature reached 135 degrees, low temperature reached -45 degrees.
Light Emitting Diode (LED) is an efficient solid-state light source based on a semiconductor PN junction that can emit light with a weak electric energy. Under a certain forward bias voltage and injection current, holes injected into the P region and N The electrons in the area diffuse to the active area and emit photons after being radiated and recombine, and the electric energy is directly converted into light energy.
