Rural solar street lamps are widely used in the construction of new rural roads. Solar street lamps are green, energy-saving, environmentally friendly, convenient to use, and have a longer lifespan than ordinary street lamps. What are the factors that affect the lifespan of rural solar street lamps?

Factors affecting the life of rural solar street lamps:

Factor 1: The light source of rural solar street lamps: The quality and type of light source are different, and the service life is also different. Currently, the light sources used for street lamps include high-pressure sodium lamps, metal halide lamps, electrodeless lamps, and led lamps, among which the utilization rate of high-pressure sodium lamps and led lamps is *. The sodium lamp is cheap and has a short service life. The LED lamp has a * service life of over 50000 hours. Theoretically, it can be used for more than 10 years with 10 hours per day. Therefore, although the price of LED lamps is high, they have a long service life, good energy conservation, and a one-time investment. In the long run, the cost is relatively low, making them a worthwhile light source to choose from;

Factor 2: Rural solar street lamp controller: The controller is the core component of solar street lamps. In the solar street lamp system, it not only controls, monitors, and protects the working state of photovoltaic modules, batteries, and loads, but also indirectly protects the load (solar street lamp), providing an effective and relatively stable working environment, Especially in critical states such as low battery power or undervoltage operation. A controller with high accuracy and stable performance will play a key role;

Factor 3: Light source starter: Different starting methods require different driving power lamps or ballasts, which has a significant impact on light sources, especially LED light sources. Nowadays, constant current sources are commonly used for driving. The advantages and disadvantages of constant current sources and whether setting parameter ranges is suitable for light sources are important, mainly based on constant current accuracy, output parameter efficiency, protection circuit, and other parameters;

Factor 4: Batteries for rural solar street lamps: The quality and performance of batteries directly affect the life of street lamps. Generally, batteries with stable quality are selected, so the price will be higher than that of ordinary manufacturers' batteries. Good batteries have a long service life.
