Abstract: A light emitting device including a light emitting element, a light transmissive member, a light guide member, and a light reflective member. The light transmissive member is disposed on an upper surface of the light emitting element, and has a lower surface including a first region facing the light emitting element and a second region positioned outside of the first region. The light guide member covers a lateral surface of the light emitting element and the second region of the lower surface of the light transmissive member. The light reflective member covers the light emitting element, an upper surface of the light transmissive member and the light guide member. One of lateral surfaces of the light transmissive member is exposed from the light reflective member.

Abstract: A lighting device includes a light-emitting component including at least one light-emitting element mounted on a base, a light guide plate guiding light emitted from the light-emitting element, a wavelength conversion member partially covering the light guide plate, and a first reflective member covering the wavelength conversion member. The light guide plate comprises two main surfaces, which include a light-extraction surface allowing light emitted from the light-emitting element to exit and a rear surface opposite to the light-extraction surface. One of two main surfaces comprises at least one recess formed in an edge region thereof. The other main surface of the light guide plate includes a part covered by the wavelength conversion member and a part exposed from the wavelength conversion member. The light-emitting element is accommodated in the recess such that a light-emitting surface of the light-emitting element faces the wavelength conversion member.
