(Points of interest)
In Japan's expressway network, many of the sections pass through the mountains, and there are many tunnels, and lighting facilities that consume the most energy among the tunnel facilities can be made more efficient and have a lower environmental impact. It is an important theme for those involved in the construction and management of highways, and if the lighting near the entrance of the tunnel is not installed in an appropriate state, it is used to the outdoor brightness just before the entrance of the tunnel. Until the driver's eyes are completely black in the tunnel entrance, and there is a risk of overlooking obstacles such as falling objects. The darkness adaptation delay phenomenon that takes time, etc. or the driver's eyes adapting to the darkness in the tunnel recognizes the tunnel exit as pure white Mau there is a concern, such as occurs and white Hall phenomenon, to the exclusion of such a risk, it is essential to more improvements to the safety of high lighting facilities.

(Conventional technology)
In consideration of such a situation, the applicant of the present application has heretofore been in one lamp housing as represented by, for example, those proposed in Patent Document 1 (1) and Patent Document 1 (2) below. By arranging a plurality of LED light sources and individually adjusting the support posture of each LED light source, the narrowness of the illumination range, which is a drawback of LED light sources, can be overcome, and a wider range can be illuminated. Technology has been developed to improve and replace conventional fluorescent lighting.

However, the LED illumination technologies shown in Patent Document 1 (1) and Patent Document 1 (2) are all intended to spread more uniform illumination over a wide range. There has not yet been a technique in which a single LED illumination lamp illuminates each traveling lane individually to have a safe brightness according to the darkness of each traveling lane in the opposite two lanes. If the LED lighting fixture of the type is used, one LED lighting fixture must be installed for each traveling lane, and safety can be ensured, while the lighting fixture installation and maintenance costs increase. It was what happened.
