What are the characteristics of led light source?

1, voltage: led adopts low-voltage power supply, and the power supply voltage is between 6-24v, which varies according to different products, so it is a safer power supply than high-voltage power supply, especially suitable for public places. 2. Efficiency: Compared with incandescent lamps with the same light efficiency, the energy consumption is reduced by 80%. 3. Applicability: very small, each unit led die is 3-5mm square, so it can be made into devices with various shapes, which is suitable for changing environments. 4. Stability: 65,438+million hours, and the light attenuation is 50% of the initial value. 5. Response time: The response time of incandescent lamp is millisecond. The response time of led lamp is nanosecond. 6. Environmental pollution: no harmful metal mercury. 7. Color: You can change the color by changing the current. The LED can easily adjust the energy band structure and band gap of materials through chemical modification, and realize multicolor emission of red, yellow, green, blue and orange. For example, with the increase of current, the red led can turn orange, yellow and finally green. 8. Price: Compared with incandescent lamps, the price of several LEDs can be equivalent to the price of an incandescent lamp. Usually, each group of signal lamps needs to be composed of 300 ~ 500 diodes. There are too many. You can go to Huaqiang Electronic Network to have a look. I also saw it on their website.
