Advantages 1. 30 watt street lamps have high illumination efficiency.LED street lamps are designed in the form of secondary optics, and the light energy emitted is concentrated in the designated area. 2. Small light decay.30w all in one solar street light銆俆he light loss of LEDs is very small, averaging less than 3 percent per year.It can be useful even after 10 years. 30w solar led street light銆?/p> Long service life.It lasts more than 50,000 hours. 4. Energy saving and environmental protection.The same lighting effect is less than one third as good as a high pressure sodium lamp.

The main reason for the problem is that the component configuration is too low, there will also be too high battery configuration, but mainly the former. After several days of rain, the battery of the street lamp system will be over-discharged, the controller will appear over-discharged protection, at this time if the solar power generation is too small, the battery voltage can not reach the recovery discharge voltage of the controller, the controller and the load has been cut off, the component capacity is too small or too long cloudy and rainy will inevitably lead to a long time not to discharge.Therefore, the battery charging time should be considered when calculating the module capacity, and it should be fully charged in 2 ~ 3 days as far as possible. Second, the design life of the battery is about 2 ~ 5 years, and the actual use of the battery is often lower than the design life, or even less than 1 year. The main reason for the problem lies in the improper configuration or work of the battery.For example, the battery capacity relative to the number of days of continuous rain is small, or the battery has been in a deep cycle when working.The second is the main reason. Some solar street lamp manufacturers, in order to reduce the above problems, often set the solar street lamp controller recovery discharge voltage is too small, resulting in the battery is often charged very little and in the discharge state, not a good use of the battery, reduce its service life.Therefore, it is necessary to reasonably set the voltage of solar street lamp controller to restore discharge.
