At this time, the installation height is 5 to 6m, and is installed at a lower position than the conventional lighting installed at 8 to 12 meters.

Thus, even when the surface lighting device 100 is installed lower than in the related art, when the driver of the vehicle 1 passes through the tunnel, the light emitted from the surface lighting device 100 is not directly reflected to the field of view to prevent glare. can do.

As shown in FIG. 2, the light irradiation distribution A of the surface lighting apparatus 100 starts from a direction orthogonal to the moving direction line F of the vehicle 1 and is distributed in a predetermined angle range.

This is to prevent the glare of the driver when the vehicle 1 is traveling in the direction of the traveling direction line (F), there is no light irradiated directly to the driver's field of view from the surface lighting device 100 from the front side of the driver. Can be.

In addition, by lowering the height of the surface lighting apparatus 100, it is possible to further reduce the power consumption under the condition of illuminating the inside of the tunnel with the same illumination.

The illuminance (lux) is a value obtained by dividing the luminance (cd) of the light source by the square of the distance (m) from the light source, and when the illumination installed at a height of 8 m is installed at a height of 6 m, the luminance of the light is 56% darker. Even if the roughness of the road surface in the tunnel is the same.

Therefore, it is expected to reduce power consumption by about 56%.
