Insert-molding of lens into rear view mirror housing

1. A rear view assembly comprising:

a housing;

an electro-optic assembly disposed within the housing;

an ambient light sensor operably coupled with the electro-optic assembly; and

an at least partially light transmissive light sensor lens integrally formed as part of the housing proximate the ambient light sensor, the light sensor lens being free of mechanical fasteners, the light sensor lens including a body and a protrusion extending from the body.

2. The rear view assembly of claim 1 , wherein an inside surface of the light sensor lens is generally flush with an inside surface of the housing.

3. The rear view assembly of claim 1 , wherein an outside surface of the light sensor lens is generally flush with an outside surface of the housing.

4. The rear view assembly of claim 1 , further comprising:

a circumferential flange that extends about the light sensor lens, and which is received in a circumferential slot defined in the housing.

5. The rear view assembly of claim 1 , wherein the protrusion is at least partially concealed such that the protrusion is not visible outside of the housing.

6. The rear view assembly of claim 1 , wherein the light sensor lens includes a generally planar circumferential portion that extends about the body of the light sensor lens.

7. The rear view assembly of claim 6 , wherein the circumferential portion extends about a plurality of parallel ridges disposed on an external surface of the body of the light sensor lens.

8. A rear view assembly comprising:

a housing;

an electro-optic assembly disposed within the housing;

an ambient light sensor operably coupled with the electro-optic assembly; and

an at least partially light transmissive light sensor lens integrally formed as part of the housing proximate the ambient light sensor, the light sensor lens including:

a body having a plurality of ridges disposed on at least one side of the body; and

a circumferential flange embedded within the housing.

9. The rear view assembly of claim 8 , wherein an inside surface of the light sensor lens is generally flush with an inside surface of the housing.

10. The rear view assembly of claim 8 , wherein an outside surface of the light sensor lens is generally flush with an outside surface of the housing.

11. The rear view assembly of claim 8 , wherein the body of the light sensor lens includes a protrusion extending therefrom.

12. The rear view assembly of claim 8 , wherein the light sensor lens includes a generally planar circumferential portion that extends about the body of the light sensor lens.

13. A method of making a rear view assembly, comprising:

providing a first mold half;

inserting an at least partially light transmissive light sensor lens into the first mold half;

operably coupling a second mold half to the first mold half;

injecting a polymeric material between the first mold half and the second mold half to define at least a portion of a rear view assembly housing;

removing the rear view assembly housing from the first and second mold halves; and

inserting an electro-optic assembly into the housing; and

positioning an ambient light sensor proximate the light sensor lens.

14. The method of claim 13 , further comprising:

at least partially encasing a protrusion extending from the light sensor lens within a wall of the rear view assembly housing.

15. The method of claim 13 , further comprising:

completely encasing a circumferential flange extending about a body of the light sensor lens within a wall of the rear view assembly housing.

16. The method of claim 13 , further comprising:

aligning the light sensor lens with the rear view assembly housing such that the light sensor lens is generally flush with an outside surface of the rear view assembly housing.

17. The method of claim 13 , further comprising:

aligning the light sensor lens with the rear view assembly housing such that the light sensor lens is generally flush with an inside surface of the rear view assembly housing.

18. The method of claim 13 , further comprising:

forming the rear view assembly housing with a receiving slot for receiving a portion of the light sensor lens.
