Document Type and Number:
WIPO Patent Application WO/2021/059558
Kind Code:
A1
Abstract:
Provided is a light-emitting device that is low-cost and has superior space efficiency while also comprising a plurality of light-outputting surfaces at different angles. A right-side part (2R) constituting the light-emitting device comprises a side-surface light guide panel (D1) and a front-surface light guide panel (D2) as a plurality of light guide panels that prismatically reflect light and output the same from the light-outputting surfaces. The side-surface light guide panel (D1) and front-surface light guide panel (D2) have different light-outputting surface angles from the adjacent light guide panel, and are disposed in succession with ends surfaces thereof abutting each other. An LED circuit board (12) is disposed at an end of the side-surface light guide panel (D1), and one of the abutting ends of the side-surface light guide panel (D1) and the front-surface light guide panel (D2) is formed into a reflective sloped face (X) that changes the angle of guided light and causes the light to be incident on the adjacent light guide panel.
