Character introduction: Wei Jiman, net name: Wei Mingzhe, gender: male, born on October 18, 1975 in Nanyang, Henan. In 1993-1995, he entered the Nanyang Normal College to study environmental art. From 1995 to 1996, he studied interior design at the Central Academy of Arts and Crafts (now Tsinghua Academy of Fine Arts), Beijing Zhuoli Lighting Design Engineering Co., Ltd. as the design director, and General Electric of the United States as the product application. Engineers, who have participated in the design of the project: Shanghai Rongxi Tunnel. At the same time, it has established and owns the domestic lighting industry, the most professional lighting design forum (ww.dengguang.com 38 degree lighting forum), after three years of development, nearly 20,000 members today. In domestic lighting designers and interior architects, there is a certain appeal, providing a platform for communication in the domestic lighting design industry.
Reporter: How to ensure the driver's visual clarity in the tunnel when designing the lighting?
Wei Mingzhe: As the driver enters and exits the tunnel, it will produce a "black hole effect" and a "white hole effect." Therefore, in order to make the human eye vision clear into the tunnel and make the motor vehicle driver feel psychological and visual comfort, a good transition and connection between the brightness in the tunnel and the natural light outside the tunnel is required, using the human eye. Visual characteristics, designed to meet the human eye adaptation curve of the tunnel brightness adjustment.
Reporter: Why is tunnel construction so rapid? What problems often arise in tunnel lighting?
Wei Mingzhe: In recent years, with the rapid development of China's transportation industry, the tunnel scheme has been widely used in the construction of traffic in mountains and hilly areas and even across the river. As a special section of the road, especially during the use of the tunnel, the external brightness of the tunnel changes greatly with time. When the vehicle enters, passes through and exits the tunnel, a series of visions will appear. problem. It can be roughly divided into the following two types: in the case of a short tunnel, people can see that the brightness outside the exit is high from the entrance, which will produce a "black box" effect; in the case of a long tunnel, when the vehicle enters the tunnel, it will feel that the hole is very dark. So that the situation near the hole can not be identified, and even the obstacles can not be identified, resulting in a "black hole" effect. When the vehicle approaches the exit of the tunnel, it sees a glare-stained white hole. At this time, the “white hole†effect is formed, which also reduces the visual function and visual comfort of the driver when exiting the hole, and cannot accurately determine the vehicle in front. The same is true when passing through a tunnel at night, which creates a "black hole" effect. These visual effects should be noted when making tunnel brightness adjustments to minimize the adverse effects of these two effects. Therefore, it is very meaningful to design a tunnel brightness adjustment method that conforms to the human eye brightness adaptation curve by utilizing human visual characteristics.
Reporter: Those tunnel lighting have their own special characteristics. Different from other road lighting, what are the special visual problems in tunnel lighting?
Wei Mingzhe: Tunnel lighting is different from other road lighting. There are several special visual problems:
(1) Before entering the tunnel (daytime): Due to the great difference in brightness between the inside and outside of the tunnel, it is seen from the outside of the tunnel that the entrance to the tunnel with insufficient illumination will see a "black hole" phenomenon.
(2) After entering the tunnel (daytime): After the car enters from the bright outside, even if it is not too dark, it takes a certain period of time to see the inside of the tunnel. This is called the “adapted hysteresis†phenomenon.
(3) At the exit of the tunnel: During the daytime, when the car passes through the long tunnel and approaches the exit, the external brightness is very high through the exit, and the exit looks like a “bright holeâ€, and there is a strong glare, the driver I felt extremely uncomfortable; at night, the opposite of the daytime, the tunnel exit did not see a bright hole but a black hole, so the driver could not see the line shape of the external road and the obstacles on the road.
