Tunnel lighting environment simulation device

Abstract

The invention discloses a luminous environment simulating device in a tunnel. The simulating device comprises a tunnel simulating box body, an artificial-light-in assembly and a natural light guiding device arranged at the top of the tunnel simulating box body. The artificial-light-in assembly comprises a lamp and a light guiding component which guides an artificial light source emitted by the lamp into the tunnel simulating box body. The light guiding component comprises a convex lens. A convex face reflector is detachably arranged on the tunnel simulating box body. The light source emitted by the lamp is converged by the convex lens and enters the tunnel simulating box body through a light-in hole formed in the tunnel simulating box body and is diverged in the periphery zone of the convex face reflector. Ideal experiment conditions are achieved, practical environments with different road conditions of a road tunnel can be reasonably simulated indoors, resource waste caused by experiments in a practical tunnel and pollution of different degrees on a tunnel entity can be avoided, the preciseness of an experiment is guaranteed, a large number of human eye reaction data under a laboratory ideal condition can be measured, and operation is easy to implement.

Description

technical field [0001] The invention relates to the field of tunnel road lighting quality testing, in particular to a tunnel lighting environment simulation device. Background technique [0002] With the continuous implementation of the "Twelfth Five-Year Plan" of the Ministry of Transport, more and more attention has been paid to accelerating the construction of a green transportation system. Highway tunnels are in the throat position in transportation. Due to their semi-closed nature, lighting and ventilation are necessary; and during the operation of tunnels, lighting and ventilation, especially electric lighting, will generate huge power energy consumption; such as the longest tunnel in my country The most mountainous highway tunnel - Qinling Zhongnanshan Highway Tunnel, the monthly lighting electricity bill alone amounts to more than 2 million yuan. According to incomplete statistics, the road tunnels that have been completed and opened to traffic in my country have exc...

Problems solved by technology

[0004] According to relevant data, the current research on lighting safety and energy saving of road tunnels mainly has the following problems: 1) For road tunnels that have been in operation, the operation of various traffic vehicles greatly reduces the safety factor of researchers; at the same time, after a period of tunnel operation, There will be a variety of working conditions, such as different degrees of pollution on the side walls and the top of the tunnel, which makes it difficult to guarantee the rigor of our experiments

2) Carrying out experiments directly in the actual unoperated road tunnels and simulating different working conditions (especially the combination of natural light and artificial light combined with light guides) will cause a lot of waste of resources, which is inconsistent with my country's current environmental protection concept, and it is difficult to operate difficult to realize
