The LED used in China 400W Led Flood Light Factory high-power white LED street light is a diode that uses a large rated working current to emit light, and the brightness of this diode is very high. Everyone knows that the power of an ordinary LED is generally 0.05W, and the working current is generally 20mA. But the wattage of high-power LEDs can exceed 2W, which is a very high-power LED lamp. So do you know what the principle of high-power white light LED is? This kind of lamp uses electro-optical conversion. Below, I will introduce its working principle.
One, working principle
The light-emitting principle of high-power white LED is mainly to use diodes to convert light energy. Do you know what diodes do? The main function of diodes is to achieve current conversion, which can convert alternating current into direct current, and can convert electrical energy into other Energy, such as light energy. The role of the diode in the high-power white light LED is as a converted solid-state 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 light LED is to convert electricity to light.
2. Performance characteristics
1. The service life is relatively long, because the diodes used in high-power LED lights are relatively durable, so the service life can be as high as 50.000 hours.
2. High-power white LED is more energy-saving, it saves 80% of electricity than high-pressure sodium lamps.
3. Green and 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, it does not pollute the environment.
4. The safety performance of high-power white LED street lights is also relatively high, because it has strong impact resistance and earthquake resistance, and it has completely changed the radiation and damage of traditional lamps to the human body.
5. The high-power white LED street lamp has no high voltage, so it does not suck dust. Ordinary LED lights can absorb dust and generate static electricity, while high-power white LEDs can completely eliminate the phenomenon of ordinary lights sucking dust and lampshades, and will not cause brightness reduction.
6. The high-power white LED street lamp has no high temperature, so the lampshade will not appear aging and yellowing. And there is no stroboscopic, and it adopts the working principle of pure DC, which can eliminate the phenomenon of traditional lamp stroboscopic, and will not cause visual fatigue of the human eyes.
The above is an introduction to the working principle of China 200W Led Flood Light Factory high-power LED street lights. High-power white LED lamps have special uses, and they are mainly used in large stages and some special places. This kind of lamp is very energy-saving and environmentally friendly, its volume is smaller than ordinary lamps, and its heat is very small, the service life is longer than ordinary LEDs, and the safety performance is relatively good. Although the high-power white LED uses high-power, it is not easy to burn out, and it will not appear high temperature and stroboscopic.
