Abstract:
A light emitting device includes a base, a first light emitting element and a first light reflecting member disposed on the base and a lens member. The first light reflecting member is positioned with respect to the first light emitting element so that emitted light from the first light emitting element is divided into a portion of the emitted light from the first light emitting element irradiating onto the light reflecting face and a portion of the emitted light from the first light emitting element traveling outside of the light reflecting face by having an edge of the light reflecting face serve as a boundary. The lens member includes a reflected light passing region having a first lens shape configured to control the travelling direction of reflected light, and a non-reflected light passing region having a second lens shape configured to control a travelling direction of non-reflected light.
