Lights are an important part of urban lighting. Traditional street lights generally use high-pressure sodium lights and high-pressure sodium lights. Because of the shortcomings of low overall light efficiency, energy is wasted. Therefore, new high-efficiency, energy-saving, long-life, high-color-rendering street lights are developed. It is of great significance to urban lighting. And LED street light as a light source for street lights, what are the benefits of LED street light ?
1. The LED street light is a semiconductor diode that has a very long life. When the luminous flux is attenuated to 80%, its lifetime reaches 25,000 hours. The life of the metal halide lamp is 6000~12000 hours, and the life of the high-pressure sodium lamp is 12000 hours.
2. The LED street lights have good seismic performance.
3. The light color of the white LEDTube is better than the high-pressure sodium lamp. At the intermediate visual level, the human eye is more likely to distinguish things in a high color temperature environment than in a low color temperature environment. The color rendering of white LED street lights is much better than the high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only 20 right and left, while the white LED street lamps can reach 65~80.
4. The LED street light can achieve a perfect dimming function. Since the working range of the LED street light is large, its light output is proportional to the operating current, so the method of reducing the current can be used for dimming.
