1. A light module, comprising:
a substrate;
a light emitting device disposed on the substrate;
a lens disposed over the light emitting device to spread light emitted from the light emitting device, the lens comprising:
a light entering surface having a concave shape in a lower region of the lens, and on which the light emitted from the light emitting device is to be incident;
a light exiting surface through which the incident light is emitted to an outside of the lens;
a plurality of legs coupled to a lower surface of the lens;
a flange connecting the light exiting surface and the lower surface of the lens; and
a gate formed on the flange,
wherein the light entering surface includes a light incident inclined surface between the lower surface of the lens and the light exiting surface,
wherein a thickness of the gate does not exceed a thickness of the flange, and
wherein the lower surface of the lens has a substantially planar shape from an outer edge of the lower surface to an inner edge of the lower surface.
