Abstract

Claims (46)

1. A method for manufacturing a blind spot indicator module for a vehicular exterior rearview mirror assembly, said method comprising:

providing a housing, wherein the housing comprises a body portion and a first connector portion extending from the body portion of the housing, and wherein the body portion is configured to be received at a receiving portion of a backplate of an exterior rearview mirror assembly that is configured for attachment to a vehicle;

providing a rear cover, wherein the rear cover comprises a lid portion and a second connector portion extending from the lid portion of the rear cover, and wherein the second connector portion extends generally parallel to the lid portion;

providing a circuit board having circuitry disposed thereat and having electrical terminals extending therefrom;

disposing the circuit board at the housing;

attaching the rear cover to a rear end of the housing to encase the circuit board at an inner cavity defined by the housing and the rear cover, whereby the electrical terminals extending from the circuit board are disposed between the first connector portion of the housing and the second connector portion of the rear cover;

wherein attaching the rear cover to a rear end of the housing with the electrical terminals extending from the circuit board disposed between the first connector portion of the housing and the second connector portion of the rear cover forms an electrical connector configured for connection to another electrical connector for electrically connecting circuitry of the circuit board at least to electrical power when the blind spot indicator module is used by an exterior rearview mirror assembly that is attached to a vehicle;

wherein the circuitry includes a light emitting diode that is operable to emit light when electrically powered; and

providing a diffuser element to diffuse light emitted by the light emitting diode.

2. The method of claim 1 , wherein the body portion of the housing comprises structure configured for connecting to structure of a backplate of an exterior rearview mirror assembly.

3. The method of claim 1 , wherein a front end of the body portion of the housing is configured for adhesive attachment at a rear side of a reflective element of an exterior rearview mirror assembly.

4. The method of claim 1 , wherein the body portion of the housing is formed from a white plastic material and comprises a diffuse reflective surface, and wherein the diffuse reflective surface diffusely reflects light emitted by the light emitting diode.

5. The method of claim 4 , wherein the diffuse reflective surface of the body portion of the housing comprises a conical-shaped surface that has an opening at a front end of the body portion of the housing.

6. The method of claim 5 , wherein the front end of the body portion of the housing comprises a recess that circumscribes the opening of the conical-shaped surface.

7. The method of claim 6 , wherein the step of providing a diffuser element comprises receiving the diffuser element at the recess.

8. The method of claim 5 , wherein the front end of the body portion of the housing is non-parallel with the rear end of the housing.

9. The method of claim 8 , wherein the light emitting diode is disposed at the circuit board off-center so as to be closer to one sidewall of the body portion of the housing.

10. The method of claim 1 , wherein the electrical terminals and the first and second connector portions comprise an electrical socket connector for electrically connecting circuitry of the circuit board to an electrical plug connector of an exterior rearview mirror assembly.

11. The method of claim 1 , wherein the circuitry includes a plurality of light emitting diodes.

12. The method of claim 1 , comprising providing an indicia element at a front end of the body portion of the housing opposite the rear end of the housing at which the rear cover is attached.

13. The method of claim 12 , wherein the indicia element comprises a triangular shaped icon.

14. A method for manufacturing a blind spot indicator module for a vehicular exterior rearview mirror assembly, said method comprising:

providing a housing, wherein the housing comprises a body portion and a first connector portion extending from the body portion of the housing, and wherein the body portion is configured to be received at a receiving portion of a backplate of an exterior rearview mirror assembly that is configured for attachment to a vehicle;

wherein the body portion of the housing comprises structure configured for connecting to structure of a backplate of an exterior rearview mirror assembly;

providing a rear cover, wherein the rear cover comprises a lid portion and a second connector portion extending from the lid portion of the rear cover, and wherein the second connector portion extends generally parallel to the lid portion;

providing a circuit board having circuitry disposed thereat and having electrical terminals extending therefrom;

disposing the circuit board at the housing;

attaching the rear cover to a rear end of the housing to encase the circuit board at an inner cavity defined by the housing and the rear cover, whereby the electrical terminals extending from the circuit board are disposed between the first connector portion of the housing and the second connector portion of the rear cover;

wherein attaching the rear cover to a rear end of the housing with the electrical terminals extending from the circuit board disposed between the first connector portion of the housing and the second connector portion of the rear cover forms an electrical socket connector configured for connection to an electrical plug connector for electrically connecting circuitry of the circuit board at least to electrical power when the blind spot indicator module is used by an exterior rearview mirror assembly that is attached to a vehicle;

wherein the circuitry includes a light emitting diode that is operable to emit light when electrically powered; and

providing a diffuser element to diffuse light emitted by the light emitting diode.

15. The method of claim 14 , wherein the body portion of the housing is formed from a white plastic material and comprises a diffuse reflective surface, and wherein the diffuse reflective surface diffusely reflects light emitted by the light emitting diode.

16. The method of claim 14 , wherein the step of providing a diffuser element comprises receiving the diffuser element at a recess at a front end of the body portion of the housing opposite the rear end of the housing at which the rear cover is attached.

17. The method of claim 16 , comprising providing an indicia element at the front end of the body portion of the housing.

18. A method for manufacturing a blind spot indicator module for a vehicular exterior rearview mirror assembly, said method comprising:

providing a housing, wherein the housing comprises a body portion and a first connector portion extending from the body portion of the housing, and wherein the body portion is configured to be received at a receiving portion of a backplate of an exterior rearview mirror assembly that is configured for attachment to a vehicle;

wherein a front end of the body portion of the housing is configured for adhesive attachment at a rear side of a reflective element of an exterior rearview mirror assembly;

providing a rear cover, wherein the rear cover comprises a lid portion and a second connector portion extending from the lid portion of the rear cover, and wherein the second connector portion extends generally parallel to the lid portion;
