1. A light emitting module, comprising:
a substrate having an insulating region and including a conductive pattern;
a light source disposed on an upper surface of the substrate and electrically connected to the conductive pattern; and
a lens disposed on the light source to disperse light emitted from the light source, the lens including:
a lower surface facing the upper surface of the substrate;
a light incident region;
a light exit surface through which light having entered the lens through the light incident region exits the lens to an outside of the lens;
a flange arranged between the lower surface and the light exit surface, and including a plurality of flange extensions extending from the flange beyond the light exit surface; and
a leg protruding from the lower surface of the lens, wherein:
the leg is coupled to the upper surface of the substrate,
the light incident region has a central axis;
the light incident region includes a protrusion facet having a rounded shape;
the protrusion facet is protruded inward toward the central axis of the light incident region; and
the flange extensions are separated from each other and arranged along a longitudinal direction of the substrate.
