There is a problem in that the cost is high and the maintenance is very troublesome because the number of light sources is large as well as the assemblability is poor.

Recently, in order to solve this problem, the light emitted from the light source can be emitted in a 360-degree direction on the plane using a conical reflecting mirror, and the reflection range of the light is adjusted by adjusting the position of the lens, However, there is a problem in that a method of simply reflecting light at 360 degrees can not realize a high light power.

Particularly, due to the nature of the installation site, the problem that a high luminous power can not be realized in a luminaires which need to illuminate a light to a long distance is a fatal disadvantage, and thus is practically useless.
