Abstract

A light emitting diode (LED) flashlight that utilizes reflection techniques to maximize light provided by the one or more light emitting diode light sources. A reflection housing includes a light housing that is suspended within the reflection housing and positions the light source toward the flashlight handle. Reflective surfaces within the reflection housing receive the light emanating from the LED light source and reflect and re-direct the light out the transparent end opposite the flashlight handle.

Claims

1. A flashlight having a power source and a light emitting end, the flashlight comprising:

a LED light source electrically connected to the power source and being positioned to direct light from the light emitting end; and

a reflection housing having inside reflective surfaces and positioned to receive the light directed away from the light emitting end and reflect it out the light emitting end.

2. The flashlight according to claim 1, further comprising a central support for supporting said LED light source within said reflection housing.

3. The flashlight according to claim 2, further comprising adjustment means for adjusting the position of said central support and thereby said LED light source within said reflection housing.

4. The flashlight according to claim 3, wherein said adjustment means comprises an adjustment knob rotatably connected to said handle, a gear mechanism connected to said adjustment knob and said central support, wherein rotation of said adjustment knob axially moves said central support.

5. The flashlight according to claim 1, wherein said reflection housing further comprises a end disposed opposite the handle, said end having a transparent end for releasing the light reflected within said housing.

6. The flashlight according to claim 1, wherein the light emitting end includes a light emitting aperture.

7. The flashlight according to claim 6, wherein the light emitting aperture is variable in size and shape.

8. The flashlight according to claim 1, wherein said LED light source comprises more than one LED.

9. The flashlight according to claim 1, wherein the light emitting end includes a magnifier.

10. The flashlight according to claim 1, wherein the light emitting end includes a diffuser.

11. The flashlight according to claim 1, wherein said LED light source comprises a surface mount diode (SMD) light source.
