Title:
INTERNAL LIGHTING-TYPE LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/175020
Kind Code:
A1
Abstract:
The present invention is provided with multiple planar light-emitting panels (100), a chassis (50), and a curved lighting panel (60). The chassis (50 supports the multiple planar light-emitting panels (100). The curved lighting panel (60) is supported by the chassis (50). In the curved lighting panel (60), light radiated from the multiple planar light-emitting panels (100) is radiated from the inner surface toward the outer surface. Using a point at which a light-emitting centroidal line (L21) intersects the lighting panel (60) as a reference point (P1), the multiple planar light-emitting panels (100) are supported by the chassis (50) so that the distances (D1) from the respective surfaces (100S) of the multiple planar light-emitting panels (100) to the reference point (P1) in the light-emitting centroidal line (L21) are the same. The light-emitting centroidal line extends from the centroid positions on the respective surfaces of the multiple planar light-emitting panels (100) perpendicularly to the surface (100S) of the planar light-emitting panel (100).
