Learn to Identify Solar Powered Street Lamp Quality
Solar powered street lamps are powered by crystalline silicon solar batteries, maintenance-free lithium batteries, ultra-bright LED lamps as the light source, and are controlled by the controller. There is no need to lay cables, subsequent installation is very simple; no AC power supply, no electricity costs, solar street lights currently occupy a large proportion in the lighting market. Solar powered street lamp market has not had a specific industry standard, many friends often ask how to choose a high quality solar street lamp. In this essay, we have summarized the following 5 quality inspection techniques for identifying the quality of solar powered street lamp:
1. Check whether the shape and workmanship of solar powered street lamps are beautiful, and there is no problem of skew, which is the basic requirement of solar street lights.
2. The battery depends on whether the battery is a special battery for energy storage. Nowadays, many small companies use starter power as the energy storage battery, which greatly reduces the lifespan of solar street lights. The hot-dip galvanized ones still have coatings in the cuts. The zinc has no coating on the cut. Half of the lamp holder is 60, and the wall thickness is about 2.8. The lower end is related to the height, and has a taper ratio, so the wall thickness is about 4.
3. Choose a well-known solar powered street lamp manufacturer, such as Shenzhen EXC-LED Technology Co., Ltd, which can often be guaranteed in many aspects, such as professional production equipment, testing equipment and automation equipment, technical teams, etc.
4. Whether the components meet the specifications is very important, because if the specifications do not meet, then it is likely to cause the internal circuit to short-circuit. Be sure to check whether the specifications of all components are qualified, and pay attention to where the light poles are. The location is more appropriate.
5. To understand the components, there are relatively more detailed types of components, mainly including solar panels, solar batteries, solar controllers, light sources and other corresponding components. The raw materials, color difference, charging current, open circuit voltage, conversion power and other factors of the photovoltaic panel should be considered. When selecting a battery, it is necessary to understand the detailed type and working environment. When selecting the controller, you should also understand the waterproof function.
6. The light source, the use of high-quality lamp beads, the lamp beads directly affect the illuminance and stability of the lamp, which is extremely important.
The above techniques for quality inspection of solar powered street lamps are shared with you. When inspecting the quality of solar street lights, you should also have an understanding of the specific environment. When choosing street light, the corresponding material requirements will naturally be different based on different climates.
