Lighting device

A lighting device comprising:

• a substrate;
• N light sources disposed on the substrate at predetermined intervals, wherein the N is a natural number of 3 or more;
• a resin layer disposed on the substrate and the light sources;
• and
• a phosphor layer disposed on the resin layer,
• wherein the phosphor layer includes a flat region overlapped with some of the N light sources in a direction perpendicular to the substrate and a curved region adjacent to the flat region,
• wherein the phosphor layer includes a seventh point where the phosphor layer and the substrate contact each other, and a fourth point where the curved region and the flat region of the phosphor layer contact each other,
• wherein the substrate includes a fifth point of the substrate that is a shortest distance from an upper surface of the substrate to the fourth point, and
• wherein the fifth point of the substrate is disposed in a region that is greater than a distance from a seventh point to a first light source closest to the seventh point and less than or equal to a radius of curvature of the curved region.

A lighting device comprising:

• a substrate;
• a plurality of 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,
• wherein the resin layer includes a first side surface, a second side surface, and an edge region in contact with the first side surface and the second side surface,
• wherein the resin layer includes an eighth point where the first side surface and the edge region are in contact with an upper surface of the substrate, a ninth point where the second side surface and the edge region are in contact with the upper surface of the substrate, and a tenth point that is an outer surface of the edge region, and
• wherein a distance from a center of a first light source closest to the edge region of the resin layer to the tenth point on the outer surface of the edge region is the same as a distance from the center of the first light source to the eighth point and the ninth point,
• wherein the outer surface of the edge region includes an eleventh point that is the shortest distance in a direction perpendicular to the substrate from the center of the first light source, and
• wherein a linear distance from the center of the first light source to the eleventh point is greater than a distance from the center of the first light source to the tenth point.
