Lighting module, lighting device, and manufacturing method thereof

A lighting device comprising:

• a substrate;
• a light source disposed on the substrate;
• a resin layer disposed on the substrate;
• and
• a first diffusion layer disposed on the resin layer,
• wherein the light source includes a first light emitting device and a second light emitting device spaced apart from the first light emitting device,
• wherein the resin layer includes a plurality of first resin portions disposed on the first light emitting device and the second light emitting device, and a plurality of second resin portions disposed between the first light emitting device and the second light emitting device,
• wherein the plurality of first resin portions overlaps the light source in a vertical direction,
• wherein upper surface of each of the plurality of first resin portions is spaced apart from the first diffusion layer at different intervals,
• wherein a height of an upper surface of each of the second resin portions with respect to an upper surface of the substrate is higher than a height of the upper surface of each of the first resin portions overlapping with the first light emitting device in the vertical direction on the upper surface of the substrate.
