Abstract
A light emitting module includes a substrate, a light emitting diode chip, and a lens. The light emitting diode chip is disposed on the substrate. The lens is coupled to the substrate and covers the light emitting diode chip. The lens includes a light incident surface and a light exit surface. The light incident surface receives light from the light emitting diode chip. The light exit surface outputs the light from the lens. The light incident surface includes a concave light incident surface and a convex light incident surface. The concave light incident surface overlaps the light emitting diode. The convex light incident surface extends from the concave light incident surface.

A light emitting module comprising:
- a substrate;
- a light emitting diode chip on the substrate;
- and
- a lens coupled to the substrate, the lens covering the light emitting diode chip,
- wherein the lens comprises:
- a light incident surface to receive light from the light emitting diode chip;
- a light exit surface to output the light from the lens;
- and
- a lower surface extending from an edge of the light incident surface towards an edge of the light exiting surface,
- wherein the light incident surface comprises:
- a concave light incident surface overlapping the light emitting diode chip;
- and
- a convex light incident surface extending from the concave light incident surface,
- wherein the lower surface of the lens abuts an upper surface of the substrate, and
- wherein a height of the light emitting diode chip from the upper surface of the substrate is smaller than a height from the upper surface of the substrate to a border between the concave light incident surface and the convex light incident surface.
A lens comprising:
- a light incident surface configured to receive light from a light emitting diode chip disposed on an upper surface of a substrate;
- a light exit surface configured to output the light from the lens;
- and
- a lower surface extending from an edge of the light incident surface towards an edge of the light exiting surface,
- wherein the light incident surface comprises:
- a concave light incident surface configured to overlap the light emitting diode chip;
- and
- a convex light incident surface extending from the concave light incident surface,
- wherein the lower surface of the lens abuts the upper surface of the substrate, and
- wherein a height of the light emitting diode chip from the upper surface of the substrate is smaller than a height from the upper surface of the substrate to a border between the concave light incident surface and the convex light incident surface.
