Claim 0:
1. A lighting device comprising:
a substrate;
a plurality of light sources disposed on the substrate;
a resin layer disposed on the substrate and covering the plurality of light sources; and
a phosphor layer disposed on the resin layer;
wherein three or more of the plurality of light sources are arranged in a column direction,
wherein three or more of the plurality of light sources are arranged in a row direction,
wherein a surface of the resin layer has a flat upper surface and a plurality of side surfaces on an outer side of the flat upper surface,
wherein at least one of the plurality of side surfaces of the resin layer has a curved surface,
wherein the phosphor layer has a first region disposed on the flat upper surface of the resin layer and a second region disposed on the plurality of side surfaces of the resin layer,
wherein the second region extends from an end of the first region to the substrate in a curved surface,
wherein the flat upper surface of the resin layer and the first region of the phosphor layer extend parallel to each other,
wherein the plurality of light sources includes a first light source arranged on an outermost side,
wherein the curved surface of the resin layer and the second region of the phosphor layer overlap the first light source in a vertical direction,
wherein the plurality of light sources includes a second light source, and the flat upper surface of the resin layer and the first region of the phosphor layer overlap the second light source in the vertical direction,
wherein a radius of curvature of the curved surface of the second region is greater than or equal to a sum of a thickness of the resin layer and a thickness of the first region of the phosphor layer in the vertical direction perpendicular to an upper surface of the substrate, and
wherein light generated from the plurality of light sources is emitted through the flat upper surface and the curved surface of the resin layer.
