Solar led street lights to work outdoors and are greatly affected by natural conditions. In order to ensure the service life of the system, it is necessary to configure itself to improve its ability to resist wind, frost, rain and snow. In use, solar street lights may have a short service life. Then, what are the factors that affect the service life of solar street lights?
Generally speaking, the main factors affecting the life of rural solar street lights are light sources, light source starters, solar controllers, and batteries.
1. Lighting source: different light sources have different lifespans. The light sources that can be selected are low-pressure sodium lamps, low-voltage induction lamps, LED lamps, low-voltage fluorescent lamps, etc. Nowadays, more sodium lamps and LED lamps are used. Sodium lamps are cheap. The life span is short. LED lights are now of good quality at 50000 hours, theoretically, 10 hours a day, 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 the LED light source. Now it is generally driven by a constant current source. The quality of the constant current source and whether the setting 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 charge 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 when the battery is insufficient or under-voltage working and other critical conditions. A controller with high precision and stable performance will play a key role. For example, sometimes solar street lights work in a flickering state. This faulty controller is one of the reasons. But not all reasons.
4. Lithium battery: Choose a lithium battery with relatively stable performance and long life. Moreover, the construction should be strict to prevent accidental factors such as water ingress. Otherwise, it will indirectly affect the life of street lights.
