Solar street lamps are now ubiquitous and have become an indispensable part of our lives. They can illuminate our way home during dark nights just like traditional electric street lamps, and the key advantage is that they are energy-saving and environmentally friendly, using no electricity at all. However, in practice, we find that the lifespan of solar street lamps can vary. What factors influence the lifespan of solar street lamps? Below, we will introduce this issue.
1. The driver of the solar street lamp: Different light sources have different starting methods and require varying electronic ballasts or LED drivers. This aspect greatly impacts the light source, especially for LED lights. Currently, direct current power sources are commonly used. The quality of the direct current power and whether the main parameters are suitable for the light source are both crucial.
2. The lighting source of the solar street lamp: It is essential to understand that different lighting sources have different lifespans. Currently, the light sources used include low-pressure sodium lamps, low-voltage LED floodlights, LED lights, and low-voltage fluorescent tubes. High-pressure sodium lamps and LED lights are predominantly used in solar street lights because high-pressure sodium lamps are relatively inexpensive but have shorter lifespans. In contrast, LED lights can last up to 50,000 hours if they provide good cost performance; theoretically, if used for 10 hours a day, they can last for ten years. Therefore, a good light source is very important.
3. The control board of the solar street lamp: The control board of a solar street lamp needs to control, monitor, and maintain the photovoltaic components, batteries, and load operation status. It must also manage the batteries to ensure their operational condition. This board provides an effective and relatively stable working environment for the solar street lamp’s load, especially under critical conditions such as insufficient battery power or undervoltage protection.
4. The battery of the solar street lamp: The battery is a crucial stage; it is essential to use a battery with stable performance. A good battery can provide long-term illumination. Additionally, it’s important to closely install the battery to prevent water intrusion, as this could directly affect the lifespan of the solar street lamp.
The above points summarize the factors influencing the lifespan of solar street lamps. Solar street lamps are much simpler to install compared to traditional electric street lamps. Unlike traditional street lamps that require a lot of wiring, solar street lamps only need to dig holes and install pre-embedded parts, as all wiring and control components are integrated into the lamp pole without needing additional arrangements.
