Guide: The emergence of electric lights, people have opened a bright era, but also promoted the rapid development of electric lights. Today, the filament developed by Edison has already faced the edge of being eliminated. The reason is that the power consumption is too large. Instead, the most popular LED lights nowadays, led lights save energy and electricity, is the first choice for contemporary people to install and decorate. Today we mainly talk about led street lights, then what are the characteristics of led street lights, now roadsides are all kinds of street lights, Led What are the advantages of street lights, today Xiaobian will tell you the characteristics of led street lights, let's learn together!
Led street light
LED street light is different from conventional street light. The LED light source is low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power type blue LED and yellow. It has high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index, etc. Unique advantages can be widely applied to roads. The cover can be made with high temperature resistance up to 135 degrees and low temperature resistance up to -45 degrees. 1, led street light features, its own characteristics - the unidirectional nature of light, no light diffusion, to ensure light efficiency.
2, led street light features, LED street lights have a unique secondary optical design, the LED street light shines on the area of the required lighting, further improving the light efficiency to achieve energy-saving purposes.
3, led street light features, LED has reached 110-130lm / W, and there is still a lot of room for development, the theoretical value of 360lm / W. The luminous efficiency of the high-pressure sodium lamp increases with the increase of power. Therefore, the overall luminous efficacy LED street lamp is stronger than the high-pressure sodium lamp; (this overall luminous effect is theoretical, in fact, the luminous efficiency of the high-pressure sodium lamp above 250W is higher than that of the LED lamp. ).
4, led street light features, LED street light light color rendering is much higher than high pressure sodium lamp, high pressure sodium lamp color rendering index is only 23, and LED street lamp color rendering index reached 75 or more, from the visual psychological point of view, to achieve the same brightness, LED street light The average illuminance can be reduced by more than 20% compared to high pressure sodium lamps.
5, led street light features, light decay is small, less than 3% of light decay in one year, still meet road requirements after 10 years of use, and high-pressure sodium light decays, has dropped more than 30% in a year or so, therefore, LED street lights are in use The power can be designed to be lower than the high pressure sodium lamp.
Led street light
6, led street light features, LED street lights have automatic control energy-saving devices, can achieve the maximum possible reduction in power in the case of meeting different lighting requirements, save energy. It can realize computer dimming, time-segment control, light control, temperature control, automatic inspection and other humanized functions.
7, led street light features, long life, can use more than 50,000 hours, providing three years of quality assurance. The downside is that the life of the power supply is not guaranteed.
What are the advantages of Led street lamps? The advantages of LED street lamps are environmental protection, no pollution, low power consumption, energy saving and environmental protection, high luminous efficiency, long life, safety, fast response and high color rendering index.
LED street light is different from conventional street light. The LED light source is low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power type blue LED and yellow. It can be widely used in roads. The outer cover can be made, with high temperature resistance up to 135 degrees and low temperature resistance. 45 degree.
LED street light refers to the street lamp made with LED lamps. It has the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response and high color rendering index. It is of great significance for urban lighting energy saving.
