How to avoid being pitted when buying solar street lights? ——Chang Hui Weapon

Some time ago, the customer called us and said that his picture is cheap, and he doesn't even know the configuration parameters of solar street lights! That’s why I was finally deceived. The seller said it was a 65-watt light board. We asked him the size of the light board, and we knew it was a 45-watt light board. The picture was cheap. In fact, this configuration was expensive! So when buying solar street lights, how can you not be pitted? Chang Hui will help you!

First consider the life of the whole lamp, there are several main factors:

1. Life issues of LED constant current source driving device:

Solar LED street light manufacturers often tell customers that I have bought the best chips and the best batteries, so the life is the best. In fact, because solar street lights use DC power supply, the voltage is low, the current is large, and every component is very good. The key is as small as the internal resistance of a terminal, the internal resistance of the wire, (because p line loss u003d i2R). Of course, in actual use, it has been proved that the most important factor affecting the life of solar street lights depends on the life of the battery and the driving circuit of the LED light source. Take the LED lamp as an example. The recognized life of LED lamp beads is 50000-100000 hours. However, the conventional technology of LED drive cross-current source has an electronic component electrolytic capacitor. The life of the electrolytic capacitor is generally 3-5 years. The best Japanese ruby u200bu200bcan only be guaranteed for 5 years, which determines the life of the driver. Our company’s LED driver is our company’s patented LED digital cross-current driving technology. It does not require electrolytic capacitors, so it does not Limited by its life, the life of LED lamp beads, LED driver, controller and solar panel are basically the same. The main materials are semiconductors.

2. Another factor is the battery life issue
