Abstract

A lens for a vehicle light assembly includes at least one ink marking provided thereon. At least a portion of the ink marking is configured such that it appears generally opaque when a light source in the light assembly is not illuminated and does not appear opaque when the light source is illuminated.

Claims

1. A lens for a vehicle light assembly having at least one ink marking provided thereon, at least a portion of the ink marking configured such that it appears generally opaque when a light source in the light assembly is not illuminated and does not appear opaque when the light source is illuminated.

2. The lens of claim 1, wherein the portion of the ink marking appears invisible to an observer when the light source is illuminated.

3. The lens of claim 1, wherein the portion of the ink marking appears faded to an observer when the light source is illuminated.

4. The lens of claim 1, wherein at least a portion of the light from the light source incident upon the ink marking passes through the ink marking when the light source is illuminated.

5. The lens of claim 1, wherein at least 30 percent of the light from the light source incident upon the ink marking passes through the ink marking when the light source is illuminated.

6. The lens of claim 1, wherein the entire ink marking is formed of the same ink composition.

7. The lens of claim 1, wherein the ink marking comprises at least one of a graphical element and a text element.

8. The lens of claim 1, wherein the ink marking comprises an ink composition comprising a transparent ink and a pigmented ink.

9. The lens of claim 1, wherein the lens comprises a polymeric material.

10. The lens of claim 1, wherein the lens is configured for use in a vehicle brake light.

11. The lens of claim 1, wherein the lens is configured for use in a center high mounted stop light for a vehicle.

12. A lighting assembly comprising:

a light source;

a lens; and

a marking provided on the lens, the marking comprising an ink that appears opaque until the light source is activated, wherein the ink is configured to allow at least a portion of the light from the light source to pass through the marking.

13. The lighting assembly of claim 12, wherein the light source comprises at least one light emitting diode.

14. The lighting assembly of claim 12, wherein the lighting assembly is a center high mounted stop light for a vehicle.

15. The lighting assembly of claim 12, wherein the marking comprises at least one of a graphical element and a text element.

16. The lighting assembly of claim 12, wherein the marking is provided on an inner surface of the lens.

17. The lighting assembly of claim 12, wherein the marking is configured such that more incident light passes through a first portion of the marking than passes through a second portion of the marking when the light source is activated.

18. The lighting assembly of claim 12, wherein the ink comprises a transparent ink and a pigmented ink.

19. The lighting assembly of claim 12, wherein at least a portion of the marking is configured to disappear to an observer when the light source is activated.

20. A method for producing a lighting assembly comprising:

providing an ink composition comprising a transparent ink and a pigmented ink; and

applying the ink composition to a surface of a lens;

wherein the ink is configured to appear opaque until lit by a light source and to allow at least a portion of the light from the light source to pass through the ink.

21. The method of claim 20, wherein the step of providing an ink composition comprises providing the ink composition on a plate having at least one depression formed therein.

22. The method of claim 21, wherein the step of applying the ink composition comprises utilizing a transfer pad to transfer the ink from the plate to the lens.

23. The method of claim 22, further comprising removing excess ink from the plate before the step of applying the ink composition.

24. The method of claim 23, wherein the step of applying the ink comprises at least one of spraying, airbrushing, screen printing, ink jet printing, lithography, and static image transfer.

25. The method of claim 20, wherein the step of applying the ink composition to the surface of the lens comprises providing an emblem on the lens.

26. The method of claim 25, wherein the emblem comprises at least one of a graphical element and a text element.

27. The method of claim 20, wherein the lens is configured for use in a vehicle light assembly.
