Lighting device enabling arbitrary distribution of light

Abstract

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.

Description

technical field [0001] The present invention relates to a lighting device realizing an arbitrary light distribution, and more particularly, to a lighting device realizing an arbitrary light distribution which can freely adjust the light distribution of individual lights. Background technique [0002] Recently, the Ministry of Environment of Korea has declared the "Law for the Prevention of Light Pollution Generated by Artificial Lighting". The law will be enforced from 1 February 2013. The main contents are: protecting national health from the abuse of artificial lighting, preventing hazards affecting ecosystems, and managing excessive and intrusive light by establishing acceptable optical radiation standards for building lighting, electronic signage, and lighting of various infrastructures. . [0003] At night, in order to prevent the generation of intrusive light indicating beams of urban infrastructure lighting, building lighting, and electronic signage that intrude int...

AI Technical Summary

Problems solved by technology

[0005] However, the structure for enlarging the light distribution of the lighting module is problematic because the light pollution is increased by increasing the penetrating light according to the increase of the light distribution area of ​​the penetrating light

In addition, the technique for adjusting light distribution using lenses is problematic because optical efficiency may be lowered by using lenses, appropriate lenses should be replaced as needed, and appropriate lenses should be made corresponding to each lamp
