摘要:
A light emitting device (1) includes a first light emitting element (30), a first light reflecting member (40) and a lens member (50). The first light reflecting member (40) is positioned with respect to the first light emitting element (30) so that emitted light from the first light emitting element (30) is divided into a portion of the emitted light from the first light emitting element irradiating onto the light reflecting face (41) of the first light reflecting element (40) and a portion of the emitted light from the first light emitting element (30) traveling outside of the light reflecting face (41) by having an edge of the light reflecting face (41) serve as a boundary. The lens member (50) includes a reflected light passing region having a first lens shape (51) configured to control the travelling direction of reflected light, and a non-reflected light passing region having a second lens shape (52) configured to control a travelling direction of non-reflected light.
