Analysis of panel application in solar LED street light

In the solar LED street light, the battery panel has a light control sensor, which is charged and discharged by the RC component, and can also help the controller to complete the switch light control, charge the battery during the day, and the like.

The solar LED street lamp adopts solar energy source. During the day, the solar panel automatically charges the battery to store electricity. The switch is automatically turned on at night, no manual management and battery replacement are required, and it can be used continuously for a long time (the life of the solar cell is 15-20 years). ), safe and save money. No need to add any cost, low cost of use, is an ideal replacement for the original street lamp. It is mainly used for lighting devices in road traffic, urban streets and other fields.

Solar LED street lamps generally have booster circuits. At present, solar street lamp manufacturers use oscillating circuits and inductors for boosting. The inductor uses a standard color code inductor. The open color circuit is used in the standard color code inductor, and the magnetic flux loss is large, so the circuit efficiency is low. If a closed magnetic circuit is used to make an inductor boost, such as a magnetic ring, the efficiency of the boost circuit will be greatly improved.

We used high-frequency welded tube magnetic rings to manufacture inductors, and conducted comparative experiments under the same conditions. Comparing the sample results, the efficiency of manufacturing the inductors with closed magnetic circuits is 20%-40% higher than that of standard color code inductors.

At the same time, pay attention to the working condition of the solar LED street lamp pole after installation. Starting from the foundation construction, the lamp position should be linearly controlled according to the main line, and the line shape should be changed according to the road design. The lamp pole is straight, and the weld bead and the inspection port should be processed. Avoid the main line direction and keep the line consistent. The inclination of the pole cantilever is to maintain the coordination of direction and angle.
