The long lifespan of LED solar street lights is one of their main advantages, attracting considerable attention. However, some LED solar street lights fail after just a year and a half of use. What causes these lights to be impractical? Is it merely due to poor quality? Furthermore, insufficient maintenance and care for the solar street light system can lead to component failures and shorten their lifespan. So, which components typically affect the lighting of solar street lights?
1. Lighting Source: Different lighting sources for solar street lights yield varying lifespans. LED solar street lights can utilize low-pressure sodium lights, low-pressure non-polluting lights, LED lights, and low-pressure fluorescent lights. High-quality LED lamps have a lifespan of approximately 50,000 hours. If used for about 10 hours a day, they can last over 10 years, while sodium lights are cheaper but have shorter lifespans. Therefore, LEDs are a recommended choice for lighting sources.
2. If the controller gets damp or water enters it, the control effectiveness of the controller will be compromised. As a result, the street lights will lose control over lighting. If the battery is in a state of over-discharge at that time, failure to repair it promptly can keep the battery in a drained state, significantly affecting both its usability and lifespan.
3. If the solar panel is partially covered or damaged, the efficiency of the solar panel will be greatly affected. Even if only 10% of the solar panel is covered, its power generation efficiency can drop by 50%. If the working current of the system does not reach the rated current, the battery may often remain in a drained state, which adversely impacts its lifespan.
4. Solar Controller: The controller not only controls, monitors, and protects the photovoltaic battery components, batteries, and loads in the solar street light system but also provides an effective and relatively stable working environment for the solar street lights, especially under critical conditions like battery undervoltage. A precise and stable-performing controller plays a crucial role in this context.
5. Solar Street Light Batteries: It is essential to choose solar batteries with stable performance. Proper installation is crucial to prevent water ingress and other unforeseen factors, which can indirectly influence the lifespan of solar street lights.
In summary, the five aspects discussed above are significant components of LED solar street lights. When purchasing, it is important to pay attention to the quality of these components and understand the parameters of the lighting devices in order to facilitate better maintenance and care of LED solar street lights.
