Title:
LIGHTING DEVICE AND LUMINOUS FLUX CONTROL MEMBER
Document Type and Number:
WIPO Patent Application WO/2018/168910
Kind Code:
A1
Abstract:
This luminous flux control member controls the distribution of light emitted from a first light-emitting element and a second light-emitting element, which are disposed in alignment with an X direction and each of which emits a light of different color from the other, the control being such that the emitted light extends in the X direction and a Z direction orthogonal thereto, while also extending toward a Y direction that is orthogonal to both directions. In particular, the luminous flux control member controls the distribution of the emitted light in such a manner that, directly above the two light-emitting elements, the emitted light from the respective light-emitting elements reaches a specific range in the X direction.
