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 Street lamp high pole lamp 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. Yunnan major Street lamp high pole lamp Discontinuous and uneven. For drivers of high-speed vehicles, this kind of light dark alternation will cause visual illusion, which is very dangerous.

1. Compared with traditional lamps, LED lighting has obvious energy-saving advantages. Just use major Street lamp high pole lamp The initial investment to replace traditional lamps has increased, but cost recovery can be achieved by saving electricity charges in a relatively short time. The earlier you replace it, the more you can enjoy the benefits of energy conservation. 2. The energy-saving performance of LED lighting is the choice to replace the traditional mining lamp. In the context of global energy contraction and the national conditions of governments at all levels to vigorously promote energy conservation and environmental protection, replacing traditional lamps will become major Street lamp high pole lamp The general trend of. There is a lot to do.

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

major Street lamp high pole lamp Coordination of color temperature and illuminance. The color temperature of light source is the color expression of light, major Street lamp high pole lamp 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.
