Title:
LIGHT-REFLECTING DEVICE AND LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/002267
Kind Code:
A1
Abstract:
In the present invention, an inner surface (210) of a light-reflecting member (200) is configured so as to be inclined in a direction opposing one end (220). The one end (220) of the light-reflecting member (200) is circular or elliptical. The light-reflecting member (200) has a part (hereinafter described as a polygonal section) in which the inner circumferential shape in a cross section parallel to the inner surface (210) is the same or similar to that of a light-emitting member (100). The polygonal section is another end (240) of the light-reflecting member (200). Further, at least a part of the inner surface (210) between the one end (220) and the polygonal section is a light-reflecting surface. Additionally, the light-emitting member (100) is attached to the polygonal section in a direction in which light is emitted to the inner surface (210).
