The power supply of LED project lights is high-voltage alternating current. During installation, please keep away from the place that is easy to access, and properly ground the lamps to avoid electric shock accidents. When wiring, the installation personnel shall select the appropriate power line according to the power of the bulb actually used, and separate the power supply to avoid affecting the normal use of flood lights. major Cast light It is designed to be waterproof and moisture-proof, and its protection grade can reach IP65. It can withstand the test of rain, but cannot work underwater, and its protection level cannot meet the requirements of underwater work. major Cast light The installation position of shall be able to bear the weight of the projection lamp, and its bearing capacity shall be 10 times greater than the weight of the projection lamp, so that the lamp can be firmly installed and the danger of falling in the future can be avoided.

1. The installation height of LED energy-saving mining lamp is determined according to the environment, because the environment will change the reflection efficiency of the lamp. Generally, the height of LED energy-saving ceiling lamp should be more than 5 meters, and the wires should not be close to the enclosure of the ceiling. If necessary, install it. If it is less than 3m, protective measures shall be taken to prevent the vehicle from contacting it. two major Cast light Waterproof and low-temperature treatment. Select the ceiling lamp with waterproof function and waterproof transformer. The chip package of the bulb is wrapped with high temperature insulating material, which can not only be waterproof, but also prevent the bulb from being damaged at low temperature under harsh conditions. three major Cast light engineering Use flat hard copper wire to connect the main line of LED energy-saving mining lamp wiring to the lamp, install one in five rings, and connect them evenly to three phase lines according to the load balance requirements.

1. Energy saving economy. First, each solar street lamp is a relatively independent system. In the process of installation and construction, there is no need to lay cables or dig roads, thus saving a lot of manpower, material resources and installation costs; In addition, it also consumes electricity, and ordinary street lights are on all day. The lamp lasts about 6 hours, consumes about 2 kWh, and the annual electricity charge is more than 300 yuan. According to 300 street lights in the urban area, the annual cost is nearly 100000 yuan. Can be saved major Cast light 。 2. Energy conservation and environmental protection. Qingdao major Cast light It is mainly composed of four departments: photovoltaic module, light-emitting diode, solar cell and controller. Photovoltaic modules absorb light in the daytime, convert solar energy into electric energy, store it in solar cells, and release illumination when it turns dark at night.

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 Cast light Combined, the lighting energy saving of the underground parking lot is effectively realized. When someone moves the car under the light, major Cast light 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.
