Lamps 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. Therefore, the development of new high-efficiency, energy-saving, long life, high color rendering index and environmental protection. Street lights are of great significance for urban lighting energy conservation. LED Light is a light source for street lamps, and it has many advantages over traditional street light sources.
First, LED Light is a semiconductor diode that has a very long lifetime. 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.
Second, the basic structure of LED Light is an electroluminescent semiconductor material, placed on a leaded shelf, and then sealed with epoxy resin to protect the internal core wire, so LED Light has good seismic performance. .
Third, the light color of the white LED tube is better than that of 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 light 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 LED light can reach 65~80.
Fourth, LED Light can achieve a perfect dimming function. Since LED Light has a large working range, its light output is proportional to the operating current, so the current can be reduced by dimming. In addition, because LED Light performs frequent switching without much damage, LED Light dimming can also be obtained by pulse width adjustment. By adjusting the duty cycle and operating frequency of the voltage, the LED Tube illumination can be effectively adjusted. strength.
