Patent attributes
A lighting device disclosed in an embodiment of the invention includes a substrate; a plurality of light emitting devices disposed on the substrate; a resin layer disposed on the substrate and the plurality of light emitting devices and including a lens portion; and a plurality of recess portions that seal a periphery of each of the light emitting devices and form a space spaced apart between the lens portion and the substrate. The resin layer includes a flat upper surface and a lower surface disposed on the substrate, and the lens portion may include a protrusion portion protruding toward a central portion of the light emitting device, a first incident surface having a convex curved surface around the protrusion portion, and a second incident surface extending perpendicular to the substrate from a lower portion of the first incident surface. A distance from an upper surface of the resin layer to the lower end of the protrusion portion is less than a thickness of the resin layer and is more than twice a distance from the upper surface of the resin layer to a high point of the first incident surface, and the refractive index of the recess portion is 1.2 or less.
