Abstract

An oral treatment device that emits light onto surfaces of a user's teeth. In one aspect, the oral treatment device includes an intraoral mouthpiece. The mouthpiece may comprise a lamp support structure comprising a lamp support surface; first and second lamps, each of the first and second lamps comprising a plurality of light emitters that generate light which is emitted from a rear surface of the lamp; each of the first and second lamps mounted to the lamp support surface, thereby forming a lamp assembly, each of the first and second lamps operably coupled to a control circuit having a power source; and a lamp retaining component coupled to the lamp support structure, a lower portion of the first lamp and an upper portion of the second lamp retained between the lamp retaining component and the lamp support surface of the lamp support structure.

First claim

What is claimed is:

1. An oral treatment device comprising:
an intraoral mouthpiece comprising:
a lamp support structure comprising a lamp support surface;
first and second lamps, each of the first and second lamps comprising a plurality of light emitters that generate light which is emitted from a rear surface of the lamp;
each of the first and second lamps mounted to the lamp support surface, thereby forming a lamp assembly, each of the first and second lamps operably coupled to a control circuit having a power source; and
a lamp retaining component coupled to the lamp support structure, a lower portion of the first lamp and an upper portion of the second lamp retained between the lamp retaining component and the lamp support surface of the lamp support structure;

wherein the first and second lamps are separated by a gap, a portion of the lamp retaining component extending through the gap and coupled to the lamp support structure.

2. The oral treatment device according to claim 1 further comprising:
each of the first and second lamps comprising:
a flexible sheet body having a front surface and a rear surface, the rear surface of the flexible sheet body forming the rear surface of the lamp; and
the plurality of light emitters embedded within the flexible sheet body; and

wherein each of the first and second lamps are mounted to the lamp support surface so that the rear surface of the flexible sheet body of each of the first and second lamps assumes a concave curvature; and
wherein a lower portion of the flexible sheet body of the first lamp and an upper portion of the flexible sheet body of the second lamp is retained between the lamp retaining component and the lamp support surface of the lamp support structure.

3. The oral treatment device according to claim 2 wherein the lamp retaining component comprises a first arched surface that contacts the lower portion of the flexible sheet body of the first lamp and a second arched surface that contacts the upper portion of the flexible sheet body of the second lamp.

4. The oral treatment device according to claim 3 wherein the first and second arched surfaces of the lamp retaining component are horizontally offset from one another.

5. The oral treatment device according to claim 2 wherein, for each of the first and second lamps, the flexible sheet body comprises a flexible lens plate and a flexible reflective layer, the plurality of light emitters disposed between the flexible lens plate and the flexible reflective layer, and wherein a rear surface of the flexible lens plate forms the rear surface of the flexible sheet body.

6. The oral treatment device according to claim 5 wherein, for each of the first and second lamps, the flexible sheet body comprises first and second electrical contacts for supplying electrical energy from the power source to the plurality of light emitters, each of the first and second electrical contacts having a contact surface that forms a portion of the front surface of the flexible sheet body of the lamp.

7. The oral treatment device according to claim 5 wherein the plurality of light emitters are light emitting diodes printed to a front surface of the flexible lens plate.

8. The oral treatment device according to claim 2 wherein the intraoral mouthpiece further comprises:
a guard component coupled to the lamp assembly, the guard component comprising:
a first frame portion defining a first window through which the rear surface of the flexible sheet body of the first lamp is exposed;
a second frame portion defining a second window through which the rear surface of the flexible sheet body of the second lamp is exposed; and
a bite platform portion located between the first and second lamps, the lamp retaining component embedded in the bite platform portion.

9. The oral treatment device according to claim 8 wherein the lamp support structure comprises a plurality of depressions formed into the lamp support surface; and wherein the guard component comprises a pad portion filling each of the depressions.

10. The oral treatment device according to claim 8 wherein the guard component is an integrally formed monolith mass of an elastomeric material.

11. The oral treatment device according to claim 1 wherein the lamp retaining component snap-locks to the lamp support structure.

12. The oral treatment device according to claim 1 wherein the lamp retaining component comprises a plate portion extending horizontally from the lamp support surface.

13. The oral treatment device according to claim 1 further comprising:
a housing containing the control circuit; and
the intraoral mouthpiece coupled to and extending from the housing; and
wherein the lamp support structure comprises an anchor element extending from a front surface of the lamp support structure that mates with the housing to fix the light assembly to the housing.

14. The oral treatment device according to claim 1 wherein the lamp support structure comprises a lamp registration feature that maintains the first and second lamps in selected positions relative to the lamp support structure.

15. The oral treatment device according to claim 1 wherein the lamp support structure comprises an upper curved edge, a lower curved edge, a first side edge extending between the upper and lower curved edges, and a second side edge extending between the upper and lower curved edges; and further comprising a guard component coupled to the lamp assembly, the guard component comprising a first wing portion extending beyond the first side edge of the lamp support structure and a second wing portion extending beyond the second side edge of the lamp support structure.

16. An oral treatment device comprising:
an intraoral mouthpiece comprising:
a lamp support structure comprising a lamp support surface;
first and second lamps, each of the first and second lamps comprising a plurality of light emitters and a substrate, the plurality of light emitters mounted to the substrate and generating light which is emitted from a rear surface of the lamp;
each of the first and second lamps mounted to the lamp support surface, thereby forming a lamp assembly, each of the first and second lamps operably coupled to a control circuit having a power source; and
a lamp retaining component coupled to the lamp support structure, a lower portion of the first lamp and an upper portion of the second lamp retained between the lamp retaining component and the lamp support surface of the lamp support structure;

wherein the substrates of the first and second lamps are distinct components.
