STRUCTURE OF DUCT FOR INSTALLING LOW HEIGHT LIGHT [0002]

More particularly, the present invention relates to a duct structure for a low light installation, and more particularly, to a duct structure for a low light installation, And a duct structure for low-maintenance installation that is easy to maintain.

Generally, roads are mainly used by automobiles or pedestrians, among which roads refer to the roads on which vehicles run, and India refers to places where pedestrians pass.

In the day when the surrounding area is easy to identify, the driver of the vehicle traveling at high speed can easily identify the lane and the other vehicle. On the other hand, at night where the vicinity identification is difficult, the driver and the road user can easily identify the road and use it safely The lighting system is installed around the road.

Generally, a road lighting device such as a conventional street light is generally installed at a high position to illuminate a wide range with a single street light. In order to illuminate the road surface far enough away from the road surface, There is a disadvantage in terms of installation cost, life span, and power consumption required.

In addition, in the case of a conventional street lamp, it is difficult to achieve the purpose of sufficiently illuminating the road surface due to scattering by the water droplet of the mist when a mist is generated because the distance between the light source and the road surface is long. The brightness is lowered as the hot spot is formed with the bright spot of the bright spot lower than the prescribed spot, and the road is not uniformly illuminated.

On the other hand, a conventional lighting device such as a streetlight installed on the road is illuminated by the backlight to the outside of the road where the illumination is not needed, so that the creature or the insect receives light even at night, causing disruption of the ecosystem.

In order to solve the disadvantages of the conventional road lighting apparatus such as the street lamp described above, Korean Registered Patent No. 10-0888347 (Irradiation Angle Adjustment Device for Road Railing Lighting Device), Korean Patent No. 10-0939477 Korean Patent No. 10-1184418 (a road lighting device set using a guide rail and a railing and a road lighting device construction method), Korean Patent Laid-Open No. 10-2015-0117891 (a road lighting device) It is installed on a structure already installed on the road while being low in height, such as a railway or a median separator, so that the road lighting device is lowered to illuminate the road uniformly, causing no glare to the driver, without disturbing the ecosystem, There is proposed a road lighting apparatus which can simultaneously illuminate a road.

However, in the case of a low-illuminating device installed in a barrier such as a conventional road guide rail or a median separator, there is a disadvantage that the wiring leading to the illuminating device has to be provided for the separate wiring for each lighting device or the wiring is exposed at all.
