First of all, we must understand the base of the solar street lamp, that is, the LED lamp head. The thin and thick shell is an important factor affecting the quality of the solar street lamp. There are aluminum substrate, aluminum plate and constant current source structure. The size and thickness of the aluminum plate can be basically determined. The quality of the base is good or bad. The heat dissipation of the LED lamp head is also an important standard for consideration. It is necessary to ensure that the heat generated by the light source is quickly discharged through the heat dissipation structure of the lamp housing to reduce light attenuation and extend life.
The second is the storage battery. It depends on whether the storage battery is a special battery for energy storage. Many small companies now use the power source as the energy storage battery, which greatly damages the life of solar street lamps.
Again, it depends on whether the pole of the solar street lamp is hot-dip galvanized or cold-dip galvanized. The difference between the two is in blocking. Hot-dip galvanized still has a coating in the blocking, and cold-galvanized one has no coating in the blocking. The half of the lamp cap is 60, and the wall thickness is about 2.8. The lower end of the solar street lamp is related to the height, and has a cone ratio, and the wall thickness is about 4. Hot galvanized lamp poles generally have a life span of over 20, while cold galvanized lamp poles generally have a life span of about 1 year.
When choosing solar street lights, you only need to be able to grasp these points and you will not be deceived. Some lawbreakers will use some poor quality materials for processing and production, so that the solar street lights produced are not guaranteed, so it is very important to identify the quality when buying solar street lights.
