During use, the bulb will be hit by wind and rain, which may cause its angle deviation, thus affecting the lighting effect. If any deviation is found, it must be adjusted in time. Check the bulb surface regularly. If on major Cast light Cracks found on the surface glass of the bulb may cause rainwater to enter the bulb, which will seriously affect the use effect and service life of the bulb. The bulb should be removed immediately and sent to the original factory for repair. Avoid all kinds of serious accidents, such as leakage. Clean the lamp regularly to maintain its brightness. Turn off the lamp before cleaning it major Cast light The power supply of the lamp shall be cleaned with a dry cloth or dry cloth to prevent the lamp from being damp, let alone with chemical or corrosive substances. Otherwise, the bulb will be corroded, which may cause accidents.

Reason 1: The cost of installing street lights on expressways is very high, and the installation distance of street lights is generally 30 meters to 40 meters. If the 50 meter street light is regarded as hundreds of kilometers on any expressway in China, the street light will be installed. major Cast light The cost is very high. The second reason is that the expressway has a high safety factor. The expressway is a closed road connecting the city and the city. In the absence of pedestrians and non motorized vehicles, urban street lights are designed for the safety and convenience of non motorized vehicles and pedestrians. Third, automobile headlights and road reflective signs are sufficient to meet the lighting needs. Xinxiang major Cast light Discontinuous and uneven. For drivers of high-speed vehicles, this kind of light dark alternation will cause visual illusion, which is very dangerous.

1. Lamp holder: it needs to be sealed through the lamp holder. major Cast light 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 Cast light 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.

Computer modeling is used to simulate the luminous angle of the reflector light source and the spatial structure of the LED reflector, track the refraction track of light, and adjust the curvature of the reflector to achieve the light intensity distribution of the reflector The functional requirements of the LED light beam angle are greatly improved major Cast light The light efficiency of the reflector reduces the possibility of astigmatism and glare. The reflective surface can be plated with orange peel and smooth. It can be more uniform and soft, without black holes, yellow circles. High reflection efficiency, no layering, high temperature resistance. The frosted mirror gently reflects light, which is suitable for occasions with weak light such as supermarkets and shopping centers. major Cast light It is not applicable to places with high illumination requirements such as industries and stadiums. If it is used for industrial lighting, it needs a reflector with high refraction and luminous efficiency, and when the light passes through the reflector, it must reduce the light loss.

(1) Material requirements: an excellent energy-saving mining lamp is made of aluminum alloy with high thermal conductivity, and its surface is sprayed with anti-corrosion metal paint to ensure heat dissipation in the future. (2) Brightness requirements: according to different use environments major Cast light There are high requirements for the brightness of. Generally, the power used in normal space and large shopping centers is mostly 50w-100w lumens above 3000, and the brightness of the lights is selected according to the size of the area. (3) Heat dissipation performance: the quality of LED energy-saving mining lamp radiator has a great impact on its quality. We produce major Cast light The thickened and accurate automobile aluminum strong convection radiator is adopted, and the working mode is eddy current heat dissipation. The service life of the light source is largely guaranteed.
