Abstract

A lighting device which is adapted to be converted between a flashlight mode and an area light mode includes a housing to receive a power supply, a light source associated with the housing and a tubular lens surrounding the light source, a reflector mounted to said device so as to slide relative to the tubular lens, the reflector including an aperture through which the light source can pass, the aperture having a shutter associated therewith whereby the shutter closes the aperture when the reflector is in a position which allows the device to be used in the area light mode.

Claims (32)

1. A method for selectively directing light in a lighting device, comprising:

sliding a reflector, relative to a light source, to a first position to produce a beam of light, the reflector having an aperture and wherein

at least a portion of the light source protrudes through the aperture; and

sliding the reflector, relative to the light source, to a second position to produce an area light and preventing light from passing through the aperture.

2. The method of claim 1 , further including enclosing the entirety of the light source within the reflector to produce the beam of light.

3. The method of claim 1 , wherein the light source is an LED.

4. A lighting device, which is adapted to be converted between a flashlight mode and an area light mode, comprising:

a housing that receives a power supply;

a light source that receives power from the power supply;

a first lens;

a second lens;

a member movable to a first position, wherein substantially all eminating from the light source passes through the first lens and a second position wherein substantially all light emanating from the light source passes through the second lens.

5. The lighting device of claim 4 , wherein the second lens is tubular and corresponds to the area light mode.

6. The lighting device of claim 5 , wherein the second lens is cylindrical.

7. The lighting device of claim 6 , wherein the light source is an LED.

8. A lighting device comprising:

a body;

a light source coupled to a first end of the body;

a member having a portion to receive at least a portion of the light source and the portion of the member having a shutter moveable to open and closed positions;

a tubular lens coupled to the first end of the body and the member, wherein the member is movable toward the body and away from the body;

a seal at a second end of the body; and

a cap located at the second end of the body and in contact with the seal, wherein the cap includes a switch.

9. The device of claim 8 , wherein the member is moved away from the body to use the lighting device in an area lighting mode.

10. The device of claim 9 , wherein light emitted from the light source extends radially outward through the tubular lens.

11. The device of claim 8 , wherein the member is moved toward the body to use the lighting device in a flashlight mode.

12. The device of claim 8 , wherein the portion of the member is cylindrically shaped and extends rearwardly therefrom.

13. The device of claim 8 , wherein the portion of the member includes an elastic membrane.

14. The device of claim 8 , wherein the member includes a forward lens having a centrally thicker portion for focusing the light from the light source.

15. The device of claim 8 , further comprising a mounting member at the first end of the body, the mounting member having a sub assembly comprising a printed circuit board.

16. The device of claim 8 , wherein the tubular lens is translucent.

17. The device of claim 16 , wherein the seal is an O ring.

18. The device of claim 8 , wherein the tubular lens is transparent.
