With the increasing scarcity of conventional energy, the use of solar energy for lighting through solar-powered LED street lights, which do not rely on conventional electricity, has become more widespread. Currently, both municipal solar street lights and rural solar street lights have gained recognition, especially as the solar energy sector has rapidly matured into a thriving industry within a few short years.
When designing solar-powered LED street light system configurations, what device failures should be avoided?
LED light sources are known for their long lifespan and can adjust their working hours in segments during nighttime. Therefore, the lighting source for solar street lights is typically configured with LEDs. It is essential to select LEDs that have a slower rate of lumen depreciation. The primary considerations for LED lamps are managing heat dissipation and ensuring constant current. Constant current can be achieved through additional constant current drivers or controllers, while heat dissipation should rely on aluminum panels. To enhance cooling, copper sheets or pipes can be added beneath the aluminum panels to effectively control temperature, thus prolonging the lifespan of LEDs.
The importance of selecting solar street light controllers.
The selection of controllers is often overlooked by engineers. The quality of controllers can vary significantly, with market prices for a 12V/10A controller ranging from 100 to 200 yuan. Although it is a smaller portion of the entire street light system’s value, it plays a critical role. The quality of the controller directly affects the lifespan of the components in the solar street light system and the overall procurement cost.
How to prevent theft of solar street lights.
In areas far from city centers, it is crucial to pay attention to anti-theft measures. Many contractors neglect effective anti-theft strategies during construction, resulting in stolen components such as solar batteries and solar panels. This not only disrupts normal lighting but also causes unnecessary financial losses. In engineering cases, batteries and panels are commonly stolen. Burying batteries underground and using concrete is an effective anti-theft practice that also helps to maintain a constant temperature. Additionally, reinforcing battery enclosures with welding on lamp poles is advisable. Low poles or surrounding climbing structures increase the risk of panel theft, so installing reinforcements or surveillance systems is recommended.
The configuration of solar LED street lights should not be compromised, or it could lead to greater losses.
Many solar street lights fail to meet normal lighting requirements, especially during prolonged rainy days and in winter when sunlight is insufficient. Aside from using inferior components, another major reason is the tendency to cut costs on materials, failing to design configurations according to needs, and reducing the standards for solar panels and batteries, ultimately resulting in inadequate lighting during cloudy days.
