Lighting device enabling arbitrary distribution of light

摘要

The present invention relates to a lighting device enabling arbitrary distribution of light, which includes: a hollow receptacle having a cover to be opened or closed; a pivot part mounted in a fixing hole provided in the bottom of the receptacle so as to be tilted and pivoted; a light module part connected through an adjustment shaft to the pivot part, the light module part being tilted and pivoted by the pivot part so as to control the distribution of light; and a fixing part for adjusting the pivot part to be fixed or to be tilted and pivoted. The present invention enables a plurality of light modules to be separately adjusted to control the distribution of light, and provides fixing means for fixing the positions of the light modules thus adjusted, so that the distribution of light may be controlled regardless of the installed position of the lighting device, thereby preventing light from penetrating into surrounding buildings.

主权项

1. A lighting device enabling arbitrary light distribution, the lighting device comprising:
one or more fixing holes provided on a fastening plate; a rotational portion inserted into the fixing hole to be tilted and rotated; an optical module portion coupled to the rotational portion, light distribution of the optical module portion being adjusted according to the tilting and the rotating of the rotational portion; and a fixing portion for fixing the rotational portion in a rotatable and tiltable state, wherein the fixing portion moves upwardly or downwardly, and wherein the fixing portion is connected to an upper side of the rotational portion, so that the rotation portion is adjusted in an unrotatable and untiltable state while the fixing portion moves downwardly.
