Solar Street Lights
are widely used across various industries. Many sectors opt for solar street lights when making their selections. However, there is a significant variation in the claimed lifespan of solar street lights in the market, with some stating 15 years while others suggest a lifespan of only three to five years. So, what is the actual lifespan of solar street lights, and what misconceptions exist? Today, I will provide a brief introduction.
Many people believe that the lifespan of the LED light source equals that of the solar street light head. This is not entirely accurate. LED light sources are semiconductor light-emitting chips with a lifespan of over 22 years. However, during usage, the light source chip generates heat, and the solar street light head comprises various components, including the aluminum substrate and housing. These parts significantly impact the overall lifespan of the solar street light head.
In addition to the misconception that the lifespan of the LED light source directly correlates with the solar street light head’s lifespan, many individuals also mistakenly believe that the lifespan of the solar street light head determines the entire lifespan of the solar street light. This perspective is not correct, as the solar street light system includes more than just the light head; it also comprises the controller, solar photovoltaic panel, and battery. The lifespan of the solar street light is heavily influenced by the controller and battery.
Furthermore, when choosing solar street lights, it is essential to avoid the oversimplified notion that the lifespan of the solar street light equates to its warranty period.
