Description

Lighting device for tunnels {LIGHTING APPARATUS FOR TUNNEL}

The present invention relates to a lighting device for a tunnel, and more specifically, to one light fixture, which can be installed by selectively applying the light distribution direction angle characteristic required at the entrance of the tunnel, the central portion of the tunnel, and the exit of the tunnel. In addition, it is possible to block the light source inside the luminaire from being directly reached by the driver's eyes entering the tunnel or driving inside the tunnel, and it is characterized by reducing the lamp replacement time for maintenance.

According to a study by the International Lighting Commission (CIE), in order to prevent traffic accidents at the entrance and exit of road tunnels, counter beam lighting is at the entrance of the tunnel, and pro beam lighting is at the exit of the tunnel. Therefore, it is recommended to apply an asymmetric light distribution that forms a beam angle at a constant angle with the road surface in the opposite direction and the same direction of the vehicle.

In other words, when entering the tunnel from the outside, the driver of the vehicle is recommended to apply the light distribution toward the entrance of the tunnel when the driver is driving. On the contrary, when exiting from the tunnel, the driver of the vehicle is driving. It is recommended to apply the light distribution toward the outside of the tunnel.

However, the conventional tunnel luminaires have asymmetrical structure of the reflector located inside the luminaire to apply the directional light distribution required at the inlet and the outlet, so that the degree of the light distribution from the luminaire to the road surface is very insufficient. Since the reflectors are applied separately for each luminaire and manufactured as it is, there is a closed end to select luminaires separately for each section.The structure of the reflectors is semi-cylindrical rather than hemispherical, so road surface roughness and directed light distribution There is a disadvantage that the efficiency for the distribution is greatly reduced.

In addition, high-pressure sodium lamps, which are mainly used in road tunnels, are designed to be suitable for long-range lamps, which are foreign products. Therefore, it is difficult to apply bulb-type lamps, which are domestic products. Although it is a general matter to be considered, it is also a problem that no high-brightness light source within the normal field of sight of the driver is directly considered while the driver is driving.

In addition, since the lamp holder and the lamp are installed inside the main body of the luminaire, it is necessary to work in a posture to look at the ceiling during maintenance and lamp replacement, which is not only inconvenient to work but also has a disadvantage in greatly reducing work efficiency.

The present invention has been made to solve the above-mentioned problems, the main object of the invention is to improve the structure of the lamp body, the installation structure of the lamp body, the reflector assembly structure, the lamp mounting structure, the cover structure The lamp body itself can be installed in different directions, and the lighting direction of the light can be adjusted more precisely in that state, and the lamp position can be adjusted to be positioned at the concave focus of the reflector. When installed at a tilted angle, the light can be prevented from being illuminated by the driver's eyes, and the maintenance work is simple and the automatic cleaning is possible.

Characteristic configuration of the present invention for carrying out the object is a heat dissipation plate for attaching to the ceiling of the tunnel, the fastening member for fixing to the bottom of the heat dissipation plate, but fixed to both ends downward to install the entire lighting fixture, the It is fixed while being held in close contact with the heat dissipation plate by using a fastening member, and the lower side is opened, and the upper side is composed of the horizontal part, the left and right inclined parts, and the lamp stabilizer and the reflector can be fixed therein. The container-shaped body having a plurality of fastening holes, the cover is connected by a hinge on one side to open and close the bottom opening of the main body, the cover except for a portion of the bottom portion to be projected by tempered glass, the inner bottom of the cover The lower part of the lamp and fixing the lamp holder to the upper part of the lamp so that the lamp can be exposed at the same time as the cover is opened.
