install major Square lamp Courtyard lamp The construction site shall be provided with safety slogans, warning signs and safety operation instruction boards, which shall not be removed or moved at will. Any movement shall be approved by the person in charge of site construction. When working on site, please pay attention to vehicle access and mechanical lifting. During normal construction, there should be no less than 2 people, and when there is only one person on site, no operation is allowed. Obey the instructions of on-site construction personnel, obey the assignment, unite and complete the production task. Materials on site shall be stacked neatly, and hazardous materials, chemical reagents and flammable materials must be placed separately. It is strictly prohibited to work in flammable and explosive places, open fire, smoking, etc. In operation major Square lamp Courtyard lamp Before that, please check whether the operation site is safe, whether the road is unblocked and whether the protective measures are complete. The tools used should be restored after the work is completed. Please wear safety belt when working at heights, cliffs and steep slopes without protective facilities.

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 Square lamp Courtyard 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 Square lamp Courtyard 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.

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 Square lamp Courtyard lamp 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 Square lamp Courtyard lamp 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.
