    Abstract: A lighting device includes a substrate, light sources having a first light source on the substrate, a resin layer sealing the plurality of light sources on the substrate; and a light transmitting layer on the resin layer. A surface of the resin layer has an upper surface and side surfaces, and the side surfaces of the resin layer has a convex curved surface. The light transmitting layer has a first flat region on the upper surface of the resin layer and a second curved region on the side surfaces of the resin layer. The convex curved surface of the resin layer and the second curved region of the light transmitting layer overlap the first light source in a vertical direction, and a corner between two adjacent the side surfaces of the resin layer has a convex curved surface.

    Abstract: The lighting device disclosed in the embodiment includes a substrate, light sources disposed on the substrate at predetermined intervals, a resin layer disposed on the substrate and the light sources, and a phosphor layer disposed on the resin layer. The phosphor layer includes a first region overlapped with some of the N light sources in a direction perpendicular to the substrate and including a flat region, and a second region extending from a side surface of the first region toward the substrate and including a curved surface. The second region includes a first point horizontally in contact with the substrate from a center of a first light source closest to the side surface of the resin layer, a second point on the curved surface, and a third point where a straight line perpendicular to the substrate passes the center of the first light source, and a second distance from the center of the first light source to the second point is greater than a first distance from the center of the first light source to the first point, and is smaller than a third distance from the center of the first light source to the third point.
