Skills for testing the quality of solar street lights
For users, it is very important to purchase high-quality solar street lights, but many users are professionals, so they can see the advantages and disadvantages of solar street lights. Therefore, here I simply teach the master to use some skills to test the quality of solar street lights. We can look at the lamp holder of the led solar street light, that is, the LED lamp holder. The thickness of its shell is a very critical factor. The structure inside the lamp holder of the street lamp includes aluminum substrate, aluminum plate and constant current source. The quality of the lamp holder can be basically determined by comparing the size and thickness of these things. Secondly, look at whether the battery used in rural solar street lights is a dedicated energy storage battery. At the moment, the street light market is mixed, and many small companies use the most common energy storage battery for power supplies, which greatly damages the life of solar street lights. Third, look at whether the pole of the solar street light is hot-dip galvanized spray or cold galvanized spray. The difference between hot-dip galvanized spray and cold galvanized spray is the secret word. The hot-dip galvanized one still has a coating in the secret word, cold galvanized spray There is no plating in the code word. The half of the lamp holder is 60, and the wall thickness is about 2.8. The lower end has a relationship with the height, and has a cone ratio, and the wall thickness is about 4 or so. Hot-dip galvanized light poles generally have a life of more than 20, while cold-dip galvanized light poles generally have a life of about 1 year.
