Lighting module and lighting device comprising same

A lighting device comprising:

• a substrate;
• a plurality of light emitting devices disposed on the substrate;
• a first reflective layer disposed on the substrate;
• a resin layer disposed on the first reflective layer and including a first surface from which light emitted from the plurality of light emitting devices is emitted;
• a second reflective layer disposed on the resin layer;
• and
• a light extraction layer disposed on the first surface of the resin layer,
• wherein the resin layer is disposed between the first reflective layer and the second reflective layer,
• wherein the first surface of the resin layer includes a convex exit surface receiving light from the plurality of light emitting devices,
• wherein the resin layer includes a plurality of convex portions having the convex exit surface,
• wherein the first surface of the resin layer includes a concave portion respectively disposed between adjacent convex portions,
• wherein the light extraction layer includes a plurality of protrusions disposed on the first surface of the resin layer,
• wherein a light extraction layer is formed of a material different from a material of the resin layer,
• wherein a refractive index of the material of the light extraction layer is in a range of 1.41 to 1.59,
• wherein a curvature of the convex exit surface and a curvature of at least one of the plurality of protrusions are different from each other,
• wherein each of the plurality of convex portions of the resin layer has a convex curved surface, and
• wherein the light extraction layer has a plurality of regions each having a convex shape, and each of the plurality of regions having the convex shape faces the convex curved surface of each of the plurality of convex portions.
