ABSTRACT:
A light-emitting device is disclosed which enables efficient use of luminous flux and achieves a desired light emission characteristic. The light-emitting device has an optical member which has an emergence surface and a plurality of optical portions, each of the optical portions including a first surface which directs light incident thereon to the emergence surface. The plurality of first surfaces are inclined on the same side with respect to the emergence surface. The light-emitting device also has a light guiding member which directs light from a light source to the plurality of optical portions from one side of a direction in which the plurality of optical portions are arranged.
