DEVICE FOR ADJUSTING ANGLE OF A RAMP INSTALLED AT TUNNEL, UNDERGROUND ROADWAY AND UNDERGROUND PARKING LOT

摘要

The present invention relates to a luminaire installed on the upper wall surface of the tunnel, underground roadway and underground parking lot of the apartment house, the luminaire (1) installed on the upper side wall of the vertical wall surface to irradiate the road surface, and the rear surface of the luminaire (1) A pair of fixing pieces 10 mounted in a longitudinal direction, a pair of first bars 20 hinged to an upper end of the fixing piece 10, and an end portion of one of the pair of first bars 20, respectively. The second bar 30 which is hinged to the second bar 30, which may be fixed at a plurality of positions of the rotational material, and hinged to an end of the other side of the pair of first bars 20, may be fixed at a plurality of positions of the rotational material. A second bar 30 ', a pair of hinge brackets 40 hinged to the pair of second bars 30 and 30', and the hinge brackets 40 are bolted to one side and to the other side. Since the fixing piece 10 includes a pair of main brackets 50 joined by a hinge, By installing a structure that can adjust the irradiation angle on the back to maintain uniform illuminance on the road surface, it is possible to secure the driver's safety during entry and exit of road tunnels, underground roads and underground parking lots of apartment houses.;Luminaire, angle adjustment
