Abstract:
A lighting device disclosed in an embodiment of the invention includes a substrate; a light source including a plurality of light emitting devices disposed on the substrate; a resin layer disposed on the substrate; and a first diffusion layer disposed on the resin layer, wherein the resin layer includes a first resin portion disposed on the light source, and a second resin portion adjacent to the first resin portion and disposed on the substrate. The upper surface of the first resin portion has an inclination and is spaced apart from the first diffusion layer, the second resin portion includes a material different from that of the first resin portion, and the second resin portion based on the upper surface of the substrate. The height of the upper surface may be greater than the lowermost height of the upper surface of the first resin portion.
