Abstract

The present embodiment relates to a light-emitting module comprising: a substrate; a light source which is arranged on the substrate and emits laser light; a holder arranged on the substrate; a diffuser lens arranged in the holder and over the light source; and a diffuser ring for supporting the diffuser lens, wherein the diffuser lens comprises a plurality of microlenses, and the holder comprises an opening formed above the diffuser lens and a stopping protrusion for inhibiting the diffuser lens from being separated through the opening.

First claim

The invention claimed is:

1. A light emitting module comprising:
a substrate;
a light source disposed above the substrate and configured to emit laser light;
a holder disposed above the substrate;
a diffuser lens disposed in the holder and disposed above the light source; and
a diffuser ring disposed between the diffuser lens and the light source,
wherein the diffuser lens comprises a plurality of micro lenses,
wherein the diffuser lens comprises a protruding portion protruding from an outer peripheral surface of the diffuser lens, and
wherein the holder comprises a first groove accommodating at least a portion of the protruding portion of the diffuser lens.

2. The light emitting module of claim 1 , wherein the holder comprises an opening formed above the diffuser lens and a stopping protrusion configured to inhibit the diffuser lens from being separated through the opening.

3. The light emitting module of claim 2 , wherein an upper surface of the diffuser lens is greater than a size of the opening.

4. The light emitting module of claim 2 , wherein at least a portion of the opening is defined by at least a portion of the stopping protrusion.

5. The light emitting module of claim 1 , wherein the diffuser ring comprises a support portion in contact with a lower portion of the diffuser lens, and a ring portion protruding from an outer periphery of the support portion.

6. The light emitting module of claim 5 , wherein the diffuser lens comprises a lens portion and a flange portion disposed on an outer periphery of the lens portion.

7. The light emitting module of claim 6 , wherein the diffuser lens comprises a protrusion protruding from a portion of a lower surface of the flange portion.

8. The light emitting module of claim 7 , wherein the protrusion has a ring shape.

9. The light emitting module of claim 7 , wherein a gap is formed in at least a portion between the diffuser lens and the diffuser ring by the protrusion.

10. The light emitting module of claim 7 , wherein the protrusion is formed closer to an inner peripheral surface than to an outer peripheral surface of the flange portion.

11. The light emitting module of claim 1 , wherein a portion of the diffuser lens is disposed between the diffuser ring and the stopping protrusion of the holder in a vertical direction.

12. The light emitting module of claim 11 , wherein the diffuser ring comprises a protruding portion protruding from an outer peripheral surface of the diffuser ring, and
wherein the holder comprises a second groove accommodating at least a portion of the protruding portion of the diffuser ring.

13. The light emitting module of claim 12 , wherein at least a portion of the protruding portion of the diffuser ring is overlapped with the protruding portion of the diffuser lens in a vertical direction.

14. A camera module comprising:
the light emitting module of claim 1 ;
a sensor disposed on the substrate; and
a lens coupled with the holder and disposed above the sensor,
wherein the holder comprises a partition wall, and
wherein the light source is disposed at one side of the partition wall and the sensor is disposed at an other side of the partition wall.

15. An optical apparatus comprising:
a main body;
the camera module of claim 14 disposed on the main body; and
a display disposed on the main body and configured to output an information captured by the camera module.
