Lighting device

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.
