Solar street lights have changed the daily lives of villagers-Lijiapu Village

Xiejiapu Township, Zhuolu County, Hebei Province, is located in the southeast of Zhuolu County. It has 21 administrative villages under its jurisdiction. It is adjacent to Beijing to the east and Zhuohe and Kongjiu highways run through the countryside. At the same time, the Lijiabao Village under its jurisdiction is adjacent to Wangjian Village, Banpu Village, Xiatuan Village, and Songjiazhuang Village. Here, there are beautiful mountains and clear waters, fresh air, rich natural resources, simple folk customs, and warm and hospitable. In addition, the natural resources in the village mainly include magnesia coal, perlite, cobalt, kaolinite, etc., and there are also cable plants, component plants, chemical plants, farm tool plants, biological fertilizer plants, steel plants and other enterprises.

The main factors affecting the service life of solar street lights are as follows:

1. Lighting source

We must know that different lighting sources have different service lives. At present, there are low-pressure sodium lamps, low-voltage induction lamps, LED lamps, low-voltage fluorescent lamps, etc. At present, there are more sodium lamps and LED lamps used in solar street lamps. Because sodium lamps are cheaper, but have a shorter service life, and for LED lamps with good quality, they can be used for 50,000 hours. In theory, they can be used for 10 hours a day. It can be used for 10 years, so a good light source is very important.

2, light source starter

Secondly, different light sources have different starting methods, requiring different ballasts or driving power lamps. This part has a very large impact on the light source, especially for LED light sources. Nowadays, it is usually driven by a constant current source. The quality of the constant current source and whether the scale of the set parameters is suitable for the light source is very important. Mainly look at: constant current accuracy, output power, maintenance circuit, parameter setting scale, etc.

3, solar street light controller

For solar street light controllers, not only need to control, monitor, and maintain the operating conditions of photovoltaic components, batteries, and loads, but also need to control the batteries to ensure the operating conditions of the batteries. At the same time, it directly maintains the solar street lights. The load provides it with a useful and relatively stable working environment, especially in critical conditions such as battery power shortage or undervoltage operation. Reminder: A high-precision, high-stability controller plays a very important role. For example, when solar street lights flicker and flicker, the controller is also one of the reasons.

4, battery

It is a very important link for the battery. It is very important to choose a battery with relatively stable performance. A good battery can illuminate for a long time, and there is one more thing to pay attention to. When the construction process requires close installation of the battery, Prevent water from entering, otherwise it will affect the service life of solar street lights.
