Abstract

A hand-held lighting device is disclosed with a handle and a head housing a first and second light source, wherein a longitudinal axis of the head is disposed at a non-parallel angle with respect to a longitudinal axis of the handle. The first light source is annular light emitting diode and the second light source is a light excited phosphor.

First claim

The invention claimed is:

1. A hand-held lighting device, comprising:
a handle;
a head disposed about a top of the handle comprising a first and second light source, wherein a longitudinal axis of the head is disposed at an angle greater than 90 degrees but less than 180 degrees with respect to a longitudinal axis of the handle;
wherein the first light source comprises an annular light emitting diode disposed about the head and oriented to direct light in a direction parallel with the longitudinal axis of the head;
wherein the second light source is disposed about the head and oriented to direct light in a direction parallel with the longitudinal axis of the head;
a lens disposed about the second light sources configured to pass light from the second light source in a direction parallel with the longitudinal axis of the head;
a base coupled to the handle, the base comprising a flat bottom configured to rest on a surface;
wherein when the base is disposed on a surface normal to a direction of gravity, the annular light emitting diode is disposed in a vertical plane that does not intersect the base; and
wherein when the base is disposed on a surface normal to the direction of gravity, the lens is disposed in a vertical plane that does not intersect the base.

2. The lighting device of claim 1 , wherein the second light source comprises a light excited phosphor comprises a coherent laser light source propagated onto a ceramic substrate.

3. The lighting device of claim 2 , wherein the light excited phosphor comprises a cylinder with a laser diode disposed about a proximal end and a phosphor substrate disposed about a distal end.

4. The lighting device of claim 1 , wherein the second light source is disposed behind the first light source within the head of the device.

5. The lighting device of claim 1 , wherein the second light source is disposed at the proximal end of one of a cylindrical chamber or a conical chamber within the head of the lighting device.

6. The lighting device of claim 1 , wherein the handle has an elliptical geometry and the head has a cylindrical geometry.

7. The lighting device of claim 1 , wherein a width of the handle is greater than a diameter of the head.

8. A hand-held lighting device, comprising:
a handle having a major axis and a minor axis, the major axis and minor axis being normal to a longitudinal axis of the handle, the major axis being normal to the minor axis;
a head disposed about a top of the handle, the head comprising a first and second light source and a lens, the first light source comprising an annular light emitting diode;
wherein a longitudinal axis of the head is disposed at an angle that is non-parallel to the longitudinal axis of the handle;
a base coupled to the handle, the base comprising a flat bottom configured to rest on a surface;
wherein when the base is disposed on a surface normal to a direction of gravity, the annular light emitting diode disposed in a vertical plane that does not intersect the base; and
wherein when the base is disposed on a surface normal to the direction of gravity, the lens is disposed in a vertical plane that does not intersect the base.

9. The lighting device of claim 8 , wherein the second light source comprises a light excited phosphor and is shaped to approximate a cylinder having a first end and a second end, the second end comprising a laser diode configured to propagate a beam of coherent laser light in a direction parallel with the longitudinal axis of the head.

10. The lighting device of claim 9 , wherein the beam of coherent laser strikes a spectrum converter disposed about the first end of the second light source, the spectrum converter converts the laser light to white light and propagates the white light in a direction parallel with the longitudinal axis of the head.

11. The lighting device of claim 9 , wherein the lens is disposed about a distal end of the light excited phosphor, the light excited phosphor configured to propagate white light in a direction parallel with a longitudinal axis of the head and through an opening in the annular light emitting diode.

12. The lighting device of claim 9 , wherein the light excited phosphor comprises a spectrum converter, the spectrum converter comprising an epoxy, silicone, ceramic, or synthetic polymer.

13. The lighting device of claim 8 , further comprising a base disposed about a bottom of the handle, the base comprising a substantially flat bottom having a surface area greater than the area of an imaginary plane passing through the head of the device at an angle normal to the longitudinal axis of the head.

14. The lighting device of claim 13 , wherein the bottom of the base is parallel with the longitudinal axis of the head.

15. The lighting device of claim 14 , wherein an axis normal to the longitudinal axis of the head passes through the second light source in the direction of the base but does not pass through the base.

16. A method of propagating light with a hand-held device:
activating a first light source disposed about a head of the hand-held device coupled to a handle and a base, said first light source comprising an annular light emitting diode disposed about a distal end of the head of the hand-held device, the annular light emitting diode comprising a void within the interior of an annular light emitting diode;
activating a second light source through the void of the light emitting diode, said second light source disposed about the head of the hand-held light device, said second disposed behind the first light source and behind a lens;
propagating a beam of light from the second light source through the void of the first light source and through the lens;
wherein when the base is disposed on a surface normal to a direction of gravity, the annular light emitting diode and lens are disposed in a vertical plane that does not intersect the base.

17. The method of claim 16 , wherein the handle comprises:
a longitudinal axis disposed at an angle that is non parallel with a longitudinal axis of the head;
a major axis and a minor axis forming an elliptical geometry, wherein the major axis is disposed at an angle parallel with a longitudinal axis of the head.

18. The method of claim 17 , wherein the handle comprises a power source disposed within a base of the handle.

19. The method of claim 16 , further comprising propagating a beam of light from the second light source wherein the beam of light comprises an intensity of 640,000 candela with an effective distance of 1 mile from the second light source.

20. The method of claim 16 , wherein the head comprises a diameter that is less than or equal to a width of the handle.
