LIGHTING DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

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.
