(1) Recommended installation height of 50W LED energy-saving mining lamp: 3-5 meters; Installation distance: 5-8m. (2) Recommended installation height of 100W LED energy-saving mining lamp: 6-8m; Installation distance: 8-10 m. (3) 120W LED energy-saving mining lamp Recommended installation height: 8-10m; Installation distance: 8-10 m. （4）150W major Multi function street lamp Recommended installation height: 10-15m; Installation distance: 8-12m. （5） major Multi function street lamp 200W Recommended installation height: 10-15m; Installation distance: 10-15m. (6) LED energy-saving mining lamp 300W recommended installation height: 15-20m; Installation distance: 20-25m. (7) Recommended installation height of 450W LED energy-saving mining lamp: 15-20m; Installation distance: 25-30m

At present, there are basically two kinds of sensors used for parking lot lighting. One is infrared sensor, which is relatively cheap. However, due to the height of the floor, the limitation of the metal tube and the influence of the radiation angle, the infrared sensor has a certain detection blind spot. The other is a microwave sensor, which can overcome the disadvantage of detecting corner blind areas, but the price is higher. These two sensors and major Multi function street lamp Combined, the lighting energy saving of the underground parking lot is effectively realized. When someone moves the car under the light, major Multi function street lamp It will run at full speed to meet the lighting demand. When there is no car and no car, the lamp is in a sleep state, and low power lighting of about 3W is maintained to maintain the required safety lighting. Low illumination, realizing energy saving of lighting.

install major Multi function street 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 Multi function street 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、 Disconnection. For "dead light", we should first determine major Multi function street lamp Is it short circuit or open circuit. 2、 The adhesive layer is peeled off. For some LED energy-saving project lights with vertical chips, the common reasons for dead lights are the peeling off of the bottom of the chip bonding layer and the peeling off of the bracket coating. 3、 The welding spot is burnt. In some cases, the dead light of the bulb may not be caused by the bulb itself, but also by the power supply used. 4、 Chip corrosion. The previous energy-saving floodlights and energy-saving floodlights are open circuit. The following is the condition of short circuit dead light. major Multi function street lamp There are many reasons for dead lights. Dead light may appear in every link from packaging, application to use.

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 Multi function street 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 Multi function street 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.

Considering that street lamps are conductors, one way is major Multi function street lamp Combination of external lightning protection and internal lightning protection. As the material of street lamp is conductor, it is equivalent to lightning rod, and downlead and grounding grid need to be installed in the design. These systems constitute the external lightning protection system. After the completion of the external lightning protection system, the fire and personal safety accidents caused by the direct lightning stroke of the street lamp can be avoided. After the completion of external lightning protection, the internal lightning protection system can protect the equipment by grounding and setting voltage protection. major Multi function street lamp The internal lightning protection system is ready to prevent induced lightning and other forms of overvoltage intrusion, which may damage the power supply. This is also beyond the protection of external lightning protection system. Therefore, the built-in internal protection and external protection can complement each other.
