Wei Mingzhe Aladdin Lighting Network Blog
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 that the driver is visually clear in the tunnel when designing the lighting?
Wei Mingzhe: As the driver enters and exits the tunnel, he will have 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 hills 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, and a black frame effect is generated. In the case of a long tunnel, when the vehicle enters the tunnel, the hole is felt black. As for the inability to identify the situation near the hole, even the obstacles are unrecognizable, creating a black hole effect. When the vehicle approaches the exit of the tunnel, it sees a glaring white hole. At this time, a white hole effect is formed, which also reduces the visual function and visual comfort of the driver when the exit is made, and cannot accurately determine the vehicle in front. The same is true when the tunnel is approaching the exit 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. Unlike 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): Since the brightness inside and outside the tunnel is extremely different, it is seen from the outside of the tunnel that the entrance to the tunnel with insufficient illumination will see black holes.
(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 adaptation hysteresis.
(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 seen through the exit is extremely high, and the exit looks like a bright hole, and there is a strong glare, and the driver feels extremely It is not suitable; at night, contrary to the daytime, the tunnel exit does not see a bright hole but a black hole, so that the driver can not see the line shape of the external road and the obstacles on the road.
