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 Factory chandelier 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. Tianjin major Factory chandelier Discontinuous and uneven. For drivers of high-speed vehicles, this kind of light dark alternation will cause visual illusion, which is very dangerous.

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 Factory chandelier 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 Factory chandelier 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.

major Factory chandelier Coordination of color temperature and illuminance. The color temperature of light source is the color expression of light, major Factory chandelier The psychological effects of light color on people include cooling and heating effects and other expansion effects. The cooling and warming effect is based on the blue-green and red orange as the two extremes of "cold color" and "warm color". It is generally believed that red has a warm feeling, while cyan has a cold and muddy feeling. The color temperature should be selected to achieve the desired lighting effect as to what kind of nightscape environment atmosphere needs to be created. The influence of color temperature on people is not only the feeling of cold and warm, but also the environmental illuminance. At low illumination levels, warm light with low color temperature is more acceptable, while at higher illumination levels, cool light with higher color temperature is more popular.

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

(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 Factory chandelier Recommended installation height: 10-15m; Installation distance: 8-12m. （5） major Factory chandelier 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

(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 Factory chandelier 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 Factory chandelier 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.
