Abstract:
A light-emitting device comprising: a base member; a plurality of first light-emitting elements disposed on the base member; a plurality of second light-emitting elements disposed on the base member; a plurality of first wavelength conversion members; and a second wavelength conversion member. The first wavelength conversion members are respectively disposed on or above the first light-emitting elements. The first wavelength conversion members each comprises a light-transmissive body mainly containing an inorganic material, and a first phosphor layer on the lower surface of the light-transmissive body. The second wavelength conversion member is disposed on the base member to cover the second light-emitting elements and the first wavelength conversion members. The second wavelength conversion member comprises an encapsulating resin and second phosphor.
