Many of the main tunnel have more lighting. How much light

Tunnel is located in the airport expressway, is an important node of the airport road, daily traffic volume is big. Before the tunnel lighting for use in the years of high pressure sodium lamp, lamp aging, also often occur. Now after modification, inside the tunnel changed into the smart according to

highway tunnel is located in the airport, is an important node of the airport, daily traffic volume is big. Previously, the tunnel lighting is a high pressure sodium lamp, have been used for many years. Lamp without aging, and often have a problem. Now after modification, the tunnel has been replaced by the intelligent lighting, intelligent lighting can according to the different environment intelligent adjusting the different light, make driving safer. The reporter understands from city lighting center, in addition to the jin tunnel, money-is-coming tunnel, tunnels, and yellow dragon house bay shaxi tunnel intelligent street lamp is installed. Driving vision clearer yesterday morning, Mr Cooper master drive by jin at the airport highway tunnel, found that the tunnel lamp is new, when vehicles out of the tunnel, the light of the difference with the outside world reduced. ； Inside and outside the light is different, if the tunnel vision will be affected, it is very unlucky for our driver. We have a period of time without running here. Surprisingly, tunnel lighting is now considering to reduce the light difference, so the vision will be more clear and safe driving. This is must praise! ； He said happily. Learned, jin tunnel lighting facilities, built in 2010, existing at the time of tunnel lighting using high pressure sodium lamp, lighting layout to four lanes two rows. Due to the long-term use of time and the light of the serious attenuation of lamps and lanterns, lights on basis of light pole degrees below standard requirement. Moreover, with the aging of lamps and lanterns, these problems begin to show up again and again, in daily life is very difficult to protect them. In addition, the original lighting system does not have perceived, patrol, alarm, intelligent control function, can't satisfy the requirement of intelligent city lighting management. In order to improve the quality of city, city lighting center recently of jin tunnel lighting, and finished the renovation on December 17th. More intelligent and energy-saving the tunnels also installed lighting city centre de-gang wang, deputy director of the city, said the reform will completely dismantled tunnel lamps and lanterns, original installation of 440 sets of three primary colors more intelligent full spectrum light emitting diode lamp color temperature. In addition to the intelligent lamp, and sensors. According to introducing, these sensors can be in the tunnel entrance surface real-time monitoring the intensity of illumination, temperature, humidity and the concentration of the tunnel, and through the artificial intelligence system for tunnel light emitting diode intelligence calibrate fine-tuning the brightness of the light and color. ； Under different temperature and time, the light color temperature can be changed to white, warm white, and yellow light, color temperature value of the lighting in order to achieve the most comfortable. ； De-gang wang said, for example, when a large sun at noon, the artificial intelligence system can take the initiative to adjust the intensity of illumination of the tunnel is 5. 5 million K white light, so that you can minimize tunnel light differences inside and outside. In different weather conditions, rain, snow, fog, haze, dust, freezing, etc. , the system can also through the sensors to collect data such as temperature, humidity, concentration, rain, accurately adjust to smoke safety lighting, the lights to make it stronger light penetration, effectively deal with safety problems. De-gang wang also said that more than three color color temperature full spectrum light emitting diode intelligent street lamp can replace a variety of ordinary monochromatic temperature led street light, the color temperature is higher, higher cost performance, long service life of lamps and lanterns, more energy efficient and can reduce energy consumption by more than 50% a year.
