Solar street light is an outdoor lighting tool, which is greatly affected by natural factors. In order to ensure its service life when designing, it needs to be configured to improve its ability to resist wind, frost, rain and snow. The main factors affecting the service life of solar street lights are as follows:
(1) Light source: Different types of light sources have different service life. Light sources generally include low-pressure sodium lamps, low-voltage induction lamps, LED lamps, etc. Nowadays, most of the light sources we use to install solar street lights are sodium lamps and LED lamps. The price of sodium lamps is relatively cheap, but the service life is relatively short; the service life of LED lamps is 50,000 hours, and if they are on for 10 hours a day, at least 10 can be used Years, but the price is more expensive than other light sources, which is why most people don’t use LED light sources.
(2) Starter. Different starting methods are different, and different ballasts or driving power lamps are required. This has a greater impact on the light source, especially LED light sources. Nowadays, constant current source is generally used for driving. The quality of the constant current source and the setting parameter range Whether it is suitable for the light source is very important, mainly depends on the constant current accuracy, output parameter efficiency, protection circuit and other parameters.
(3) Controller. The solar controller controls the multi-channel solar cell array to charge the battery and the battery to supply power to the solar inverter load. In the case of insufficient battery power, a controller with high accuracy and stable performance will play a key role.
(4) Battery. The stability of the battery directly affects the service life of solar street lights, so when choosing a battery, you must choose a more stable one.
