Claims
- 1. For use in a vehicle visor, a vanity mirror assembly for providing variable illumination for use of the vanity mirror in low ambient light conditions, said mirror assembly comprising a glass mirror having a back face, a polymeric film substrate mounted adhesively to the back face of said mirror, and electrical circuit components printed on said substrate, said components including a resistor element printed on said substrate and a wiper associated with said resistor element for defining a variable resistance; said component further including means for receiving at least one lamp for the illumination of said mirror, terminals for receiving operating power from a vehicle power source and means for coupling said variable resistance to said terminals such that a lamp received by said assembly can be selectively activated to control the intensity of light therefrom.
- 2. The mirror assembly of claim 1 wherein the substrate covers and is mounted adhesively over substantially the full expanse of the back face of the mirror.
- 3. The mirror assembly of claim 2 further comprising a layer of adhesive mounting the substrate to the back face of the mirror.
- 4. The mirror assembly of claim 1 wherein said components are screen-printed on the substrate in particle-laden polymeric inks.
- 5. The mirror assembly of claim 1 wherein said resistor element is a resistive component of a voltage divider.
- 6. The mirror assembly of claim 5 wherein said resistor element is screen-printed on the substrate in carbon particle-laden polymeric ink.
- 7. The mirror assembly of claim 6, wherein the substrate covers and is mounted adhesively over substantially the full expanse of the back face of the mirror.
- 8. The mirror assembly of claim 7 further comprising a layer of adhesive mounting the substrate to the back face of the mirror.
- 9. A mirror and circuit for use in an illuminated vanity mirror assembly for a vehicle visor comprising:
- a mirror having a size and shape to fit in a vehicle visor and having a forward reflective side and a rear surface;
- a polymeric film substrate including an electrical circuit formed on one side thereof, said electrical circuit including a pair of spaced electrodes near opposite ends of said mirror for receiving lamps for the illumination of said mirror, said circuit further including a resistance element coupled to said electrodes for controlling illumination from said lamps coupled to said electrodes; and
- adhesive means coupling said film substrate to said rear surface of said mirror.
- 10. The apparatus as described in claim 9 wherein said adhesive means is integral with said polymeric film.
- 11. The apparatus as described in claim 9 and further including a wiper arm coupled to said resistance element to form a voltage divider for varying the illumination from lamps coupled to said electrodes.
