Daylighting and lighting play an important role in road tunnel traffic safety

　　'One sky ditches into a thoroughfare

　　 In the tunnel, in order to create a safe and comfortable traffic environment, it is particularly important to control the lighting 'whatever you want'.

　　 At present, the most important problem facing tunnel lighting is the safety accident caused by 'black'.

　　1. Tunnel entrance is black

　　 In 2014, 31 people died in the Yanhou tunnel in Shanxi. The main cause of the incident was that the tunnel entrance was too dark, which made it impossible to see the tunnel clearly when trucks entered the tunnel. The internal conditions caused a series of disasters, which caused a series of disasters, which was very tragic.

　　 In fact, when a car enters a tunnel with no lighting or an unqualified lighting condition at a speed of 60 km/h or more, it will be completely dark. Even if the lights are turned on in the tunnel, The effect is also minimal, and the light and dark changes in the line of sight can easily lead to the sudden occurrence of an accident.

　　2. The basic lighting section of the tunnel is black

　　 If the light of the basic lighting section of the tunnel does not meet the standard, even if the lights are kept on, there is still a traffic safety risk.

　　In case, your car light happened to be broken in the tunnel, and rescuers came to the tunnel, and the black light was blind and you couldn’t find your car; in case, the inside of the tunnel needs to be repaired due to fire, water leakage, etc. Later, the car couldn't see the road conditions ahead, and drove straight ahead...the consequences could not be imagined.

　　 was born in the sun and grows in the landscape. The scenery should be beautiful, but the inside is dark. Common architectural lighting is turned on after the sun sets, but tunnel lighting requires 'the brighter the sun outside, the brighter the lighting at the entrance and transition sections; the darker the outside light, the darker the light inside the tunnel.'

　　 In fact, it is most appropriate to choose natural light sources to meet this requirement. According to the report, the current annual energy consumption of road tunnel lighting is equivalent to the annual electricity consumption of a megacity with a population of nearly 50 million. The use of electricity measures still requires energy consumption; the non-electric measures are not bright enough. The existing road tunnel electro-optical lighting technology restricts the improvement of the quality of road tunnel lighting, and the use of sunlight will be a new direction for the development of road tunnel lighting!

　　The light pipe daylighting system is a new way of using natural light to daylight. It is different from ordinary tunnel lighting and pays more attention to safety settings. The application of natural light puts indoors and outdoors in the same dimension, taking into account the changes in people's light and dark sights, and paying attention to the lighting design of the transition section, which greatly reduces the safety hazards caused by the black hole.

　　 In addition to realizing natural light illumination in the tunnel, the photoelectric integrated system also integrates an LED device. The LED device can automatically sense the external light situation. When the external light is insufficient, it can automatically dim and perform LED lighting. Lighting problems in the tunnel when natural light is insufficient, reducing the risk of tunnel accidents.

　　Light pipe daylighting system to reduce tunnel lighting safety accidents, 'zero' risk products are worth applying!
