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

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

The working voltage of a single bulb for LED tunnel lighting is very low, about 3V, so the power consumption of a low-voltage working environment is half of the power required for the same strong light. The tunnel lamp has a long service life and does not need regular maintenance and inspection. After a period of use, the traditional major Municipal lighting The brightness of the tunnel lamp will be greatly reduced, but its attenuation is only 20% of that of the tunnel lamp. Moreover, the tunnel lamp is small in size and can be made into various shapes to adapt to various environments. The shell of the tunnel lamp is of integrated design, which is durable and not easy to be damaged. Each light source inside can be installed and removed separately, which is very convenient in the future maintenance process, and the overall design can ensure good heat dissipation effect. The heat dissipation rack inside the shell, the airflow and the heat emitted by the full contact with the air, effectively reduce the major Municipal lighting And prolongs the service life of the tunnel lamp.

Main pole of high pole lamp: major Municipal lighting When the height of the main pole exceeds 20m, the steel plate with a wall thickness of 5.6mm is usually used as the main material. After the overall welding of the high pole lamp, the internal and external surface layers need to be hot-dip galvanized and qualified galvanized. This process can ensure that the main pole will not rust for 15 years. Lifting system: the lifting system is regarded as the core part of the high pole lamp. The landing action of the light panel depends entirely on the landing system. The landing system of high pole lamp is mainly hoist and wire rope. First, install the elevator on the main rod. Weathering and rain will not cause line aging. Secondly, the hoist seldom starts. If major Municipal lighting If the light source has not been damaged in ten years, it will not need to be touched in ten years. Lamp cap: Whether it is LED lamp cap or low pressure sodium lamp, the light source is the main symbol of the whole set of high pole lamp. If the light source is broken and the high pole lamp is broken, the selection of light source quality is particularly important.

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