Problems solved by technology

Statistics show that most accidents occur at the exit and entrance of the tunnel. One of the important reasons is that there is a large difference in light intensity between the exit and the entrance of the tunnel. The sudden change of light and dark or the sudden change of light brightness will easily cause the driver to pass through the tunnel. Stimulate the eyes and cause "glare", that is, temporary visual failure; at the same time, the light in the tunnel is all at the same light intensity value, which obviously prolongs the time of dark adaptation and light adaptation, deteriorates the driver's sight distance, and greatly increases the speed of the driver.

Abstract

The invention discloses an intelligent illuminating apparatus for an expressway tunnel. The illuminating brightness of a lamp group in the expressway tunnel can be intelligent controlled in real timeaccording to the actual lighting and change situation thereof in an environment outside an exit and an entrance of the tunnel, so that when driving through the tunnel, eyes of a driver can gradually adapt to the apparent change of the brightness inside and outside the tunnel, the darkness adaption and brightness adaption time can be shortened, the sight distance of the driver can be improved, theirritation of the sudden change of the illuminating brightness for the driver can be reduced, and the transportation safety of the expressway tunnel can be ensured.

Description

technical field [0001] The invention belongs to the technical field of traffic lighting, in particular to an intelligent lighting device for highway tunnels. Background technique [0002] my country is a mountainous country. Nearly two-thirds of the country's total area is mountains, hills and relatively rugged mountainous areas. In these areas, in order to ensure the technical requirements of high-grade highways, tunnels are often used to pass through mountains and ridges. Although highway tunnels have widely used conventional traffic safety signs such as road surface markings, entrance and exit speed limits, height limits, and prohibition of non-motor vehicles; in long tunnels, monitoring, communication, fire protection, ventilation, lighting, etc. Traffic safety facilities; but tunnel traffic accidents are common in recent years. Statistics show that most accidents occur at the exit and entrance of the tunnel. One of the important reasons is that there is a large differe...
