How to judge the quality of solar street lights

As we all know, a solar street light is composed of 5 major components, which are light pole, light source, battery, solar panel, and controller. To know the quality of solar street lights, we can judge according to solar street light battery components and their light sources. First: The luminous efficiency of the LED lamp beads used in the LED light source solar street lamp is very important. Although some LED lamp beads can reach a certain wattage, they often fail to achieve the luminous effect. When selecting, choose the LED lamp beads. Good lamp beads can improve light efficiency, reduce light decay, and have higher color rendering. The radiator of the solar street light source is an important factor to improve the service life of the LED light source and also an important factor to reduce the light attenuation. If the heat dissipation is poor, the service life of the light source will be greatly shortened. Second: battery solar street lamp battery, try to choose high-quality gel batteries, some manufacturers will use some poor batteries, such batteries often do not meet the expected service life, a certain capacity of batteries have the corresponding weight, you can Weigh the solar street lamp battery, and the weight difference must not be used. Third: The quality of solar panels, solar street lights, solar panels is hard to tell from the naked eye, but we can check his sealing, process details, as well as the thickness of the tempered glass and the quality of the aluminum frame. Some unscrupulous businesses save costs Inferior tempered glass and thin aluminum frames are used as fixing devices for solar cells. Such solar street light solar panels are often easily damaged during transportation, and have poor resistance to hail during use and are easy to enter rain, so We must pay attention to these when choosing solar panels. The quality of solar street lights is determined by its configuration. We do not choose without purpose when purchasing. We must carefully check the quality of each configuration to ensure that solar street lights can be used normally.
