The LED used by the high-power white LED street lamp is a diode that emits light using a large rated working current, and the brightness of this diode is very high. We all know that the power of ordinary LED is generally 0.05W, and the working current is generally 20mA. However, the wattage of high-power LED can exceed 2W, which is a very high-power LED lamp. So do you know what is the principle of high-power white led? This lamp is the use of electro-optical conversion, below, to introduce its working principle.

Principle and characteristics of white high-power LED lamp

First, the working principle

The luminous principle of high-power white LED is mainly the use of diodes to convert light energy, diodes do not know what you know? The main role of the diode is to achieve the conversion of current, alternating current can be converted into direct current, and electrical energy can be converted into other energy sources, such as light energy. The role of the diode in the high-power white LED is as a solid device, which can convert electrical energy into light energy, because its structure is composed of a PN junction chip and an electrode optical system. The working principle of high-power white LED is to convert electricity to light.

Second, performance characteristics

1, the service life is relatively long, because the diode used by the high-power LED lamp is relatively durable, so the service life can be as high as 50.000 hours.

2, high-power white LED is relatively energy-saving, it is 80% energy-saving than high-pressure sodium lamps.

3, green environmental protection is one of the characteristics of high-power white LED street lights, because it does not contain lead and mercury, which can pollute the environment, so there is no pollution to the environment.

4, the safety performance of high-power white LED street lights is also relatively high, because its impact resistance and seismic ability is very strong, and completely changed the traditional lamp on the human body radiation and damage.

5, high-power white LED street light is no high pressure, so it does not absorb dust. Ordinary led lights will absorb dust, will produce static electricity, and high-power white LED can completely eliminate the phenomenon of ordinary light dust absorption and lampshade black, will not lead to brightness reduction.

6, high-power white LED street lights are not high temperature, so the lampshade will not appear aging and yellowing. And no stroboscopic, the use of pure DC working principle, can eliminate the traditional lamp stroboscopic phenomenon, will not cause visual fatigue of the human eye.

　　The above is the introduction of the working principle of high-power LED street lights. High-power white LED lamps have special uses, it is mainly used for large stages and some special places. This lamp is very energy saving and environmental protection, its volume is smaller than the general lamps, and its heat is very small, the service life is longer than the ordinary led, and the safety performance is also better. Although the high-power white LED uses high-power, it is not easy to burn out, and there will be no high temperature and stroboscopic.
