Solar street lights work outdoors and are greatly affected by natural conditions. In order to ensure the service life of the system, it is necessary to improve its ability to resist wind, frost, rain and snow from its own configuration. In use, you may encounter a short life span of solar street lamps. So, what are the factors that affect the service life of solar street lamps?
In general, the main factors affecting the life of rural solar street lamps are light sources, light source starters, solar controllers and batteries.
1. Illumination light source: Different light sources have different lifespans. The light sources that can be selected include low-pressure sodium lamps, low-voltage electrodeless lamps, LED lamps, and low-pressure fluorescent lamps. Now more sodium lamps and LED lamps are used. Sodium lamps are cheap. Short life. LED lights are now of good quality at 50,000 hours, theoretically 10 hours a day and can be used for more than 10 years. So first choose a good light source.
2. Light source starter: different starting methods are different, and different ballasts or driving power lamps are required. This part has a great influence on the light source. Especially LED light source. Now generally use constant current source drive. The quality of the constant current source and whether the set parameter range is suitable for the light source are very important. Mainly look at: constant current accuracy, output efficiency, protection circuit, parameter setting range, etc.
3. Solar controller: The solar street light system not only controls, monitors, and protects the working status of photovoltaic components, storage batteries, and loads. While effectively controlling the working state of the battery, it also indirectly protects the load (solar street light), providing it with an effective and relatively stable working environment, especially in critical conditions such as insufficient battery power or undervoltage operation. A controller with high accuracy and stable performance will play a key role. For example, sometimes solar street lights will work in a flickering state. This faulty controller is one of the reasons. But not all reasons.
4. Battery: Use a battery with relatively stable performance. And the construction should be strict, prevent accidental factors such as water ingress. Otherwise, it will also indirectly affect the life of the street lamp.
