All-in-one street light is a very cost-effective product for our customers and friends. After buying it back, everyone naturally wants it to be used for a longer time. So, what factors will affect the service life of integrated street lights? This requires specific understanding.
1. Light source: different light sources have different service life. The light sources that can be selected are low-pressure sodium lamps, low-voltage induction lamps, LED lamps, and low-voltage fluorescent lamps. Nowadays there are more sodium lamps and LED lamps. Sodium lamps are cheap. Short life. LED lights are now of good quality, 50,000 hours, theoretically 10 hours a day, can be used for more than 10 years. So choose the light source first.
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. It is very important to determine the quality of the constant current source and whether the set parameter range is suitable for the light source. Mainly look at: constant current accuracy, output efficiency, protection circuit, parameter setting range, etc.
3. Solar controller: The integrated street light system not only controls, monitors and protects the working status of photovoltaic modules, batteries and loads. While effectively controlling the working state of the battery, it also indirectly protects the load (integrated street light), providing an effective and relatively stable working environment, especially under critical conditions such as insufficient battery power or under-voltage operation. High-precision, stable performance controllers will play a key role. For example, sometimes integrated street lights work in a flashing state. Controller failure is one of the reasons. But not all.
4. Battery: Choose a battery with relatively stable performance. And the construction should be strict to prevent accidental factors such as water ingress. Otherwise it will indirectly affect the life of the street lamp.
