1. The quality and type of light source: different types of light sources will affect the service life of solar street lamps. Nowadays, solar street lamps are commonly used as LED lamps and energy-saving lamps. Energy-saving lamps are marked by the country. The average lifespan is greater than 6000 hours, and the service life of LED lamps is average. More than 50,000 hours, that is, energy-saving lamps can be used for more than 2 years and LED lamps can be used for more than 10 years.
There is also product quality, which determines the service life of the light source.
2. Controller: The controller is one of the core components of solar street lights.
It plays a commanding role in the entire solar street light system. It not only controls, monitors, and protects the working status of photovoltaic components, storage batteries, and loads, but also effectively controls the working status of storage batteries, but also indirectly protects the load (solar led street lights). It provides an effective and relatively stable working environment.
Therefore, a controller with stable performance and reliable quality will greatly extend the service life of solar street lights.
3. Storage batteries: colloidal batteries and lithium batteries are commonly used in solar street lights. Although colloidal batteries are cheaper than lithium batteries, the service life of colloidal batteries is much lower than that of lithium batteries. The colloidal batteries used in China have the longest service life. Not more than 4 years, and the minimum service life of lithium batteries is 5 years, so solar street lights in many places do not light up after 3 or 4 years. The main reason is that the gel battery has a short service life.
