Waterproof function of solar street light

A practical comparison between the effects of solar street lights and the use of mains lamps. A mains lighting fixture is complicated to install: there are complicated operating procedures in the mains lighting project. First, cables must be laid, and the cable trench must be excavated and laid dark. A large number of basic projects such as pipes, pipe threading, and backfilling. Then carry out long-term installation and debugging, if any line has problems, a large area of u200bu200brework is required. In addition, the terrain and lines are complex, and the cost of labor and auxiliary materials is high.　　Solar street light is easy to install: when solar street light is installed, there is no need to lay complicated lines, just make a cement base and fix it with stainless steel screws. Contrast 2 The high electricity cost of mains lighting fixtures: The work of mains lighting fixtures has fixed and high electricity costs, and it is necessary to maintain or replace lines and other configurations for a long time. The maintenance cost increases year by year. Solar lighting lamps are free of electricity charges: Solar lighting lamps are a one-time investment, without any maintenance costs, and the investment costs can be recovered in three years, and long-term benefits. Comparing the three mains lighting lamps have potential safety hazards: Mains lighting lamps bring many safety hazards due to construction quality, landscape engineering transformation, material aging, abnormal power supply, and conflicts between water and electricity pipelines.　　Solar street lamp rainproof problem　　The main phenomenon is that the charging and discharging controller is exposed to water and damp, causing the circuit board to short circuit, burning out the control device (transistor), and seriously causing the circuit board to be corroded and deteriorated and cannot be repaired. There are two main ways to enter the water: one is to enter the light pole from the reserved hole at the top of the light pole along the solar cell module and the light source lead; the other is to immerse from the gap in the door of the light pole warehouse; plus the high temperature in the warehouse , Resulting in high humidity in the warehouse, causing damage to the controller. Therefore, it is also not negligible to protect the controller from damp and damage.
