Abstract

A headlamp includes a base having a front face defining a first imaginary plane along the front face and a first imaginary line orthogonal to the first plane. A light assembly is rotatably secured about the front face to the base. The light assembly includes a bezel having a rear surface defining a second imaginary plane along the rear surface and a second imaginary line orthogonal to the second plane so that the intersection of the first line and the second line defines a rotation angle that varies with the rotation of the light assembly relative to the base, thereby changing the attitude of the headlamp light assembly.

Claims

1. A headlamp comprising:

a base having a basal face and a front face, the front face defining a first plane therealong and a first normal line to the first plane;

a light assembly comprising;

a bezel having a rear surface, the rear surface defining a second plane therealong and a second normal line to the second plane wherein the first normal line and the second normal line intersect to define a rotation angle;

a battery case attached to said bezel and defining an enclosed volume therebetween;

a battery located within the volume;

a light source located at least in part within the volume; and

a switch selectively forming an electrical circuit between said light source and said battery;

wherein said light assembly rotation relative to said base changes the attitude angle.

2. The headlamp of claim 1 wherein said base is hollow and is adapted to receive a portion of said light assembly therein.

3. The headlamp of claim 1 wherein said base further comprises a fastener for securing said headlamp to a headband or a helmet.

4. The headlamp of claim 1 wherein said light assembly further comprises a reflector.

5. The headlamp of claim 4 further comprising a jewel.

6. The headlamp of claim 1 further comprising a crystal in contact with said bezel.

7. The headlamp of claim 1 wherein said light source is a light emitting diode.

8. The headlamp of claim 1 wherein said light source is a plurality of light emitting diodes.

9. The headlamp of claim 1 wherein said battery case has a removable cap affording access to the enclosed volume.

10. The headlamp of claim 1 wherein said light assembly rotates about a race incorporated into said base.

11. The headlamp of claim 10 wherein a circumferential flange of said battery case engages said race.

12. The headlamp of claim 1 wherein said light assembly rotates about an axial pin interconnecting said base and said battery case.

13. The headlamp of claim 1 wherein the canting angle is between 130°

and 230°

.

25. A process for adjusting the attitude of a headlamp emission comprising the steps of:

constructing a headlamp having a bezel and a base according to claim 1;

activating a light source emission from said headlamp; and

rotating said bezel relative to said base.

26. The process of claim 25 wherein said bezel rotates 360°

relative to said base.

27. The process of claim 25 wherein said bezel rotates about a race.

28. The process of claim 25 wherein said bezel rotates about an axial pivot pin.

14. A headlamp comprising:

a hollow base having a basal face and a front face, the front face defining a first plane therealong and a first normal line to the first plane, said base having a race having a structure for the rotation of a light assembly normal to the first plane;

wherein said light assembly comprises;

a bezel having a rear surface defining a second plane therealong and a second line normal to the second plane wherein the first normal line and the second normal line intersect to define a canting angle;

a battery case attached to said bezel and defining an enclosed volume therebetween;

a battery within the enclosed volume and a light source at least partially located within the enclosed volume;

a light emitting diode located at least in part within the volume; and

a switch to selectively form an electrical circuit between said light emitting diode and said battery;

wherein rotation of said bezel relative to said base changes the canting angle.

15. The headlamp of claim 14 wherein said base further comprises a fastener for securing said headlamp to a headband or a helmet.

16. The headlamp of claim 14 wherein said light assembly further comprises a reflector.

17. The headlamp of claim 16 further comprising a jewel.

18. The headlamp of claim 14 further comprising a crystal in contact with said bezel.

19. The headlamp of claim 14 wherein said light source is a light emitting diode.

20. The headlamp of claim 14 wherein said light source is a plurality of light emitting diodes.

21. The headlamp of claim 14 wherein said light assembly rotates about a race incorporated into said base.

22. The headlamp of claim 21 wherein a circumferential flange of said battery case engages said race.

23. The headlamp of claim 14 wherein said light assembly rotates about an axial pin interconnecting said base and said battery case.

24. The headlamp of claim 14 wherein the canting angle is between 130°

and 230°
