With the rapid economic development, the urbanization process is accelerating, and road construction is also in constant fiery progress. Street lights are one of the most important infrastructures in urban and rural construction, so its market is constantly expanding. solar street light is an independent lighting system that uses solar energy resources and converts it into electricity to provide lighting for people. When people buy street lights, they are actually most concerned about its brightness, and they all hope to buy street lights with better brightness to meet their lighting needs. The solar street light has become one of the important choices for people’s outdoor road lighting because of its good luminous effect, high brightness and long service life. So what factors will affect the brightness of solar street lights?
The configuration of solar street lights is a direct factor that affects the brightness of street lights, usually referring to the power of solar panels and the size of battery capacity. The greater the power of the solar panel, the higher the battery capacity, and the higher the overall brightness of the street light. Some people covet the cheap price of solar street lights and choose low-profile solar street lights, so the brightness is definitely not guaranteed. Therefore, if you want to choose a solar street light with good brightness, try not to choose a low configuration. But we can’t blindly pursue high configuration. High configuration means that the price of solar street lights is also higher. The most important thing is to meet your own lighting needs. Usually, if it is a residential area, rural areas, etc., the lighting requirements are not so high. If it is a highway, places such as tennis courts have relatively high requirements for lighting.
The internal light beads of solar lights are mainly composed of LED chips. The number of lumens of the LED chip is an important factor reflecting the light efficiency (brightness). At present, many solar street light manufacturers on the market use chips from Taiwan Jingyuan, and the number of lumens is 110LM/W. And the lumens of LED chips of big brands will be higher. For example, the lumens of Philips are 120~130LM/W, and the lumens of Preh chips can be as high as 150LM/W. Therefore, if you want high brightness of solar street lights, try to choose LED chips from big brands. High-quality LED chips have high luminous efficiency. Under the same configuration conditions, the brightness of solar street lights can be increased by a quarter.
The height of the pole and the spacing of the street lights will also affect the brightness of the solar street lights. Generally, the distance between street lights in scenic spots or parks is about 7 meters. If the light poles are too high, the brightness that people feel under the street lights will also become smaller. If the distance between the street lights is too large, the brightness of the solar street lights will also be reduced. However, if the distance is too small, it is easy to waste resources. The height of the light pole and the spacing of the solar street light should be based on the usage scenarios of the lights
Whether the solar street light will be blocked by the surrounding tall buildings and trees is also an important factor affecting its brightness. If the solar street lights are to be installed on both sides of the road, we have to consider whether there are green plants on both sides of the road. Because solar street lights are converted into electricity by absorbing solar energy. If there is something blocking it, the area of the solar panel to absorb solar energy will be reduced, the absorbed solar energy will be reduced, and the converted electric energy will naturally be less. Therefore, when installing street lights at the beginning, it is necessary to choose a suitable installation location to avoid the subsequent situation of insufficient absorption of solar energy.
