Title:
LIGHTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/043441
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a lighting apparatus capable of achieving a more diverse light distribution. In this lighting apparatus, a plurality of hinge devices (5) link a plurality of light source units (3) to a base (2), in such a manner that each of the plurality of light source units (3) are rotatable around a first axis between a first position and a second position. A plurality of rotating mechanisms link each of the plurality of light source units (3) to the plurality of hinge devices (5) in such a manner that each of the plurality of light source units (3) are rotatable around a second axis intersecting with the first axis. The plurality of hinge devices (5) are constituted in such a manner that the rotation directions for each of the plurality of light source units (3) when rotating from the first position to the second position are different. The plurality of rotating mechanisms govern the rotating range around the second axis of each of the plurality of light source units (3) in such a manner that, when each of the plurality of light source units (3) is in the first position, a standard state is assumed, wherein the plurality of light source units (3) are grouped and the light exit surface (3222) of each of the plurality of light source units (3) is oriented outward.
