摘要： A lighting device may include a substrate, light sources, a resin layer disposed on the substrate and the light sources, and a phosphor layer disposed on the resin layer. 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. At least one of the plurality of side surfaces of the resin layer has a curved surface. 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. Light generated from the plurality of light sources is emitted through the flat upper surface and the curved surface of the resin layer.

摘要： The lighting assembly disclosed in the embodiment of the invention includes a substrate, light emitting devices on the substrate, a first resin layer covering the light emitting devices, and at least one second resin layer on the first resin layer, and a first cover disposed on an outer periphery of the substrate along an outer periphery of the substrate of the lighting module. The second resin layer is disposed on upper and side surfaces of the first resin layer, and the second resin layer includes at least one of phosphor and ink particles. The first cover includes an opening portion from which the second resin layer protrudes, a substrate cover portion disposed on an upper surface of the substrate around the opening portion, and a side cover portion extending lower than a side surface of the substrate from the substrate cover portion. An upper surface of the substrate cover portion may be disposed lower than the upper surface of the first resin layer.

摘要： 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.
