LED LIGHTING LAMP TOOL FOR STREETLAMP, CAPABLE OF EASILY ADJUSTING LIGHTING DIRECTION

摘要

The present invention relates to a lighting lamp tool for a streetlamp, capable of easily adjusting a lighting direction. More specifically, the lighting lamp tool for a streetlamp is provided to easily adjust a lighting direction and a lighting range of a lighting source by a simple configuration. The lighting lamp tool for a street ramp, which is intended to radiate light to a lighting area requiring light, comprises: a cover body having an opening formed in one surface, such that a lighting source is installed in the opening, and having a power supply unit, an electrical device, and a circuit installed therein to drive the lighting source; first light shield plates formed of plates with a predetermined length and having both end portions installed at regular intervals in the opening of the cover body to be able to rotate; and second light shield plates formed of plates with a predetermined length and having both end portions installed at regular intervals in the opening of the cover body to be able to rotate wherein the second light shield plates are installed to intersect with the first light shield plates. In the lighting lamp tool for a streetlamp, when the direction directing the lighting area is defined as a front direction, the first light shield plates are separately installed in the direction to connect front and rear end portions of the cover body. Each of the first light shield plates is formed in a plate shape with the length and has installation holes formed at regular intervals in an end portion facing the cover body during assembly towards an inner side from the end portion. Each of the installation holes in the first light shield plates has an inner diameter larger than a rotating radius of the second light shield plates, such that the second light shield plates pass through the installation holes in the first light shield plate, respectively.;COPYRIGHT KIPO 2018
