Abstract: A lighting module includes: a circuit board having a plurality of first recesses; an optical lens disposed on the circuit board and including a plurality of protrusion portions; a light emitting device disposed between the optical lens and the circuit board; and an absorbing layer disposed on the circuit board. The optical lens includes: a bottom surface, a second recess having an incident surface concave at a center region of the bottom surface, and a first exit surface. Each of the protrusion portions protrudes from the bottom surface toward the circuit board. The second recess is disposed on the light emitting device, and a portion of each of the protrusion portions is disposed in each of the first recesses. The absorbing layer surrounds at least one of the protrusion portions on the circuit board.

Abstract: The lighting module disclosed in the embodiment includes: a circuit board having a plurality of first recesses; an optical lens disposed on the circuit board and including a plurality of protrusion portions; a light emitting device disposed between the optical lens and the circuit board; and an absorbing layer disposed on the circuit board. The optical lens includes: a bottom surface, a second recess having an incident surface concave at a center region of the bottom surface, a first exit surface having a convex curved surface. The protrusion portion protrudes from the bottom surface toward the circuit board. The second recess is disposed on the light emitting device, and a portion of the protrusion is disposed in the first recess. The absorbing layer surrounds at least one of the plurality of protrusion portions on the circuit board. The absorbing layer surrounding the protrusion portion is disposed in a region of 2.
