Solar street light quality is good or bad, mainly depends on the following parts.
A solar street lamp head, that is, the LED lamp head, the thickness of the shell is certainly a key factor, because long-term exposure to the outside, the wind, sun and rain, the thickness requirements for the shell is also relatively high, and now the construction of the street lamp head are aluminum substrate, aluminum plate and constant current source, when buying, focus on comparing these aspects can basically determine the quality of the head of good or bad.
Second, the solar street light battery, as far as the market is concerned, there is no uniform standard, resulting in a mixed market, many small companies in order to save costs, using ordinary energy storage batteries instead of lithium batteries, so this greatly damaged the life of solar street lights. So also as look at the battery of the electric car, must look more.
Third, the external solar street lights, you also need to consider the street light poles, the market is generally galvanized spraying, but be sure to note that this is divided into hot and cold galvanized, hot galvanized in the incision still have a coating, cold galvanized in the incision without a coating. In terms of service life, hot-dip galvanizing is generally much longer than cold-dip galvanizing, and then the wall thickness of the light pole is generally recommended to choose about 3-4.
