WIPO Patent Application WO/2024/014467
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is, with respect to indoor lighting, to reduce the number of installed lighting devices so as to reduce the obtrusiveness of a ceiling. [Solution] This lighting device comprises: a light source; and a dual light distribution optical element having two light distribution regions. The dual light distribution optical element distributes light emitted by the light source such that the light has a light intensity peak in two different directions that establish a predetermined dual light distribution angle. The dual light distribution angle can be adjusted by changing the distance between the light source and a lower surface of the dual light distribution optical element such that the distance has a value between a minimum value and a maximum value.
