1. Lamp holder: it needs to be sealed through the lamp holder. major City circuit lamp The waterproof treatment of lamp cap can ensure the service life of street lamp. Therefore, the selection of street lamp housing is very important. 2. Controller: when selecting, pay attention to whether the style is waterproof. When installing the controller, it is usually placed in the road to better avoid wind and sun exposure. 3. Battery: it needs to have certain waterproof performance. In order to install the battery, please bury the battery about 40cm underground to avoid flooding. After that, test major City circuit lamp Head to check whether the street lamp lights up normally. If it is opened, it can be used normally; otherwise, it needs to be replaced. Light poles need to be hot-dip galvanized to ensure smooth surface, no color difference, no pinholes, and no skin peeling after use.

The solar street lamp is composed of six main components: solar panel, lithium battery, controller, LED lamp holder, lamp pole and ground cage; major City circuit lamp It is made of LED lamp holder. It consists of three parts: lamp pole and grounding cage. Since the solar street lamp uses unique solar panel, lithium battery and controller components, it can easily get rid of the tedious wiring process in the building, complete the charging process independently, and automatically turn on and off the sunshine time according to the lighting conditions, or even automatically adjust the brightness of the street lamp according to the brightness in the daytime; However, urban circuit lights cannot get rid of the independent existence of municipal electricity. Cables need to be embedded at an early stage to ensure the subsequent installation of street lights. In order to control the lighting time, major City circuit lamp Power distribution can only be carried out on the mains. Time control can be installed on the box, and the brightness control of lighting can only be completed by adding corresponding only equipment.

The life of LED mining lamp depends largely on the level of heat dissipation, and the main way to improve the level of heat dissipation is to transfer the excess heat generated by the chip through the radiator and radiator. At the same time, major City circuit lamp The main parameters related to LED heat dissipation are thermal resistance, junction temperature, temperature rise, etc. Thermal resistance is the quotient obtained by dividing the difference between the effective temperature of the equipment and the temperature of the external designated reference point by the steady-state power consumption in the equipment. It is an important parameter indicating the degree of heat dissipation of equipment. Junction temperature refers to the temperature of the semiconductor junction of the main heating part in the LED device. It reflects major City circuit lamp Temperature value that can be withstood under working conditions. Temperature rise refers to the temperature rise of the enclosure environment. It refers to the difference between the temperature of LED equipment shell and the ambient temperature. This is a temperature value that can be directly measured, which can directly reflect the heat dissipation degree around LED devices.

1. When you buy back the LED ceiling lamp, please do not install it. Please read the label of the bulb carefully and read the installation manual, and then install and use the LED ceiling lamp according to the instructions, otherwise it may be dangerous. 2. Please be careful not to change it during cleaning and maintenance major City circuit lamp Do not replace the parts of LED ceiling lamp at will. After cleaning and maintenance, install the bulb as it is, and do not omit or install the bulb components incorrectly; 3. Maintenance is required during use major City circuit lamp To extend its service life. Wipe with dry cloth frequently, and pay attention to prevent moisture intrusion to avoid rust or long-term leakage and short circuit; Wipe as much as possible to avoid affecting light penetration.
