Claim 9:
10. 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 the plurality of light sources is arranged in three or more rows and three or more columns,
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 two of the plurality of side surfaces of the resin layer have 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,
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 first light sources arranged on an outermost row,
wherein the first light sources in the outermost row overlap the second region of the phosphor layer in a vertical direction, and
wherein the curved surface of the resin layer overlaps the first light sources in the 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.
