[Guide] Streetlights are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps. The low-efficiency of high-pressure sodium lamps as a whole has caused huge waste of energy. Street lamps are an important part of urban lighting. Traditional street lamps often use high voltage. The shortcomings of sodium lamp and high-pressure sodium lamp have a huge waste of energy. Therefore, the development of new high-efficiency, energy-saving, long-life, high color rendering index and environmentally friendly street lamps is of great significance for urban lighting energy conservation.
LEDLight is a light source for LED street lights, and it has many advantages over traditional street light sources.
First, LEDLight is a semiconductor diode that has a very long lifetime. When the luminous flux decays 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. LED street lights last longer.
Second, the basic structure of LEDLight is an electroluminescent semiconductor material, placed on a leaded shelf, and then sealed with epoxy resin to protect the internal core wire, so LEDLight has good seismic performance.
Third, the light color of the white LEDTube is better than that of the high pressure sodium lamp. Under the visual level between China and Argentina, 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 LEDLight is also much better than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only 20 right and left, while white LEDLight can reach 65~80. LED street lamps have better color rendering.
Fourth, LEDLight can achieve a perfect dimming function. Since LEDLight has a large operating range, its light output is proportional to the operating current, so the current can be reduced by dimming. In addition, because LEDLight performs frequent switching without much damage, LEDLight dimming can also be obtained by pulse width adjustment. By adjusting the duty cycle and operating frequency of the voltage, the LEDTube's luminous intensity can be effectively adjusted. LED street lights are more efficient and convenient.
