The calculation of solar street light system

With the rapid development of national economy, the expansion of cities, a and a road was completed, the demand of street lamp is bigger and bigger. And LED technology matures, laying off makes the traditional high pressure sodium lamp lights, LED lights for road lighting

with the rapid development of national economy and the expansion of cities, a and a road has been built, the demand for street lamp is becoming more and more big. As light-emitting diode technology matures, the traditional high pressure sodium lamp has been knocked out, the light emitting diode lamp has become the first selection of road lighting. Now, LED street light penetration rate is increased year by year, I believe that a few years later, it will appear in every way. So everyone must be very curious why the LED street lamp is so popular, what are its advantages? No defects? Today, LED street lamp manufacturers will take you to simply understand the advantages and disadvantages of it. It is well known that the LED street lamp differs from traditional street lamps in the street lamp head. Traditional street lamps using high pressure sodium lamp cap, and leds lamps using led street lamp. Light emitting diode lamp advantages: 1. High lighting efficiency. Leds lamps in the form of secondary optical design, the light energy is concentrated in the designated area. 2. Light attenuation is very small. Light emitting diode light attenuation is small, light attenuation per year on average less than 3%. Even after 10 years, it still has very high use value. 3. Long service life. It can be used more than 50000 hours. 4. Energy conservation and environmental protection. The energy required for the same lighting effect less than a third of the high-pressure sodium lamp. Light emitting diode lamp shortcomings: 1. Although led street lamp light attenuation is low, but compared with the high power led street light, small power led street lamp light attenuation are still high. 2. 2 the color of the light. Led street lamp is generally white. Due to manufacturing defects and the lens match error, will produce yellow aperture, affect the whole lighting effect. In short, everything happens for a good side, the advantages outweigh the disadvantages of led street light, in many ways than the traditional high pressure sodium lamp, so it is very popular with the people and penetration are rapidly improving.
