Abstract

A flashlight having an elongated body having opposed first and second ends. A first lamp is a high-intensity variable brightness white light source located at the first end. A number of additional lamps are positioned at the first end. The additional lamps include at least two different output wavelengths different from each other and from the first lamp. A first switch on the flashlight selectively operates to select the output wavelength of the flashlight by selectively enabling different lamps based on the condition of the switch. A power storage element and control circuitry are connected to the lamps and to the switch.

Claims

1. A flashlight comprising:

a first lamp having a first output wavelength;

a second lamp having a different second output wavelength;

a power storage element;

a first switch having a first condition in which the first lamp is in an enabled state, and a second condition in which the second lamp is in an enabled state;

a second switch operable to illuminate any lamp that is in an enabled state;

wherein the second switch has an off position, an intermediate position, and a fully actuated position, and wherein the first switch operates to limit illumination to only one of the lamps when the second switch is in the intermediate position; and

wherein the first lamp operates with at least two different brightness levels, and wherein when the first lamp is enabled by the first switch and the second switch is in the intermediate position, the first lamp operates at a dimmed brightness level, and wherein when the first lamp is enabled by the first switch and the second switch is in the fully actuated position, the first lamp operates at a brighter brightness level.

2. The flashlight of claim 1 wherein the first lamp operates with at least two different brightness levels, and the second switch is operable to sustain illumination of the first lamp at a brighter of the levels in response to momentary actuation of the second switch to the fully actuated position, and a release from the fully actuated position.

3. The flashlight of claim 1 wherein the flashlight has a body with a central axis, and wherein the first lamp is oriented on the axis and has a substantially white light, and wherein the second lamp is positioned off-axis.

4. The flashlight of claim 3 wherein the second lamp is a member of a set of lamps arranged annularly about the first lamp.

5. The flashlight of claim 4 wherein the set of lamps includes at least two different output wavelengths.

6. The flashlight of claim 1 wherein the second lamp has an infra red output wavelength.

7. The flashlight of claim 1 including a third lamp having a different output wavelength compared to the first and second lamps, and wherein the first switch has a third condition operable to enable the third lamp while disabling the first and second lamps.

8. The flashlight of claim 1 wherein the first switch is an annular switch movable through a range of positions.

9. The flashlight of claim 8 wherein the flashlight is an elongated body having a front end at which the lamps are mounted and an opposed rear end, and wherein the first switch is a ring encircling the body adjacent to the front end.

10. The flashlight of claim 9 wherein the second switch is positioned at the rear end of the body.

11. A flashlight comprising:

an elongated body having opposed first and second ends;

a first lamp comprising a high-intensity efficiently variable brightness white light source at the first end;

a plurality of additional lamps at the first end;

the additional lamps including at least two different output wavelengths different from each other and from the first lamp;

a single first switch on the flashlight having a plurality of conditions and selectively operable to select the output wavelength of the flashlight by selectively enabling different lamps based on the condition of the switch;

a power storage element and control circuitry operably connected to the lamps and to the switch;

the flashlight including a second switch having an off position, an intermediate position, and a fully actuated position;

the first lamp being operable at a first dim brightness level, and a second maximum brightness level;

the first lamp being illuminated at the second brightness level when the second switch is in the fully actuated position; and

when the second switch is in the intermediate position, the illumination being provided by at least one of;

the first lamp at the first brightness level; and

at least a selected one of the additional lamps.

12. The flashlight of claim 11 wherein additional lamps surround the first lamp.

13. The flashlight of claim 11 wherein the first switch is a rotatable ring encircling the body.

14. The flashlight of claim 11 wherein the white light source is an LED.

15. A flashlight comprising:

a first lamp having a first output wavelength;

a second lamp having a different second output wavelength;

a power storage element;

a first switch having a first condition in which the first lamp is in an enabled state, and a second condition in which the second lamp is in an enabled state;

a second switch operable to illuminate any lamp that is in an enabled state;

wherein the first lamp operates with at least two different brightness levels, and the second switch is operable to sustain illumination of the first lamp at a brighter of the levels in response to momentary actuation of the second switch to the fully actuated position, and a release from the fully actuated position; and

a third lamp having a different output wavelength compared to the first and second lamps.

16. The flashlight of claim 15 wherein the flashlight has a body with a central axis, and wherein the first lamp is oriented on the axis and has a substantially white light, and wherein the second lamp is positioned off-axis.

17. The flashlight of claim 16 wherein the second lamp is a member of a set of lamps arranged annularly about the first lamp.

18. The flashlight of claim 17 wherein the set of lamps includes at least two different output wavelengths.

19. The flashlight of claim 15 wherein the second lamp has an infra red output wavelength.

20. The flashlight of claim 15 wherein the first switch has a third condition operable to enable the third lamp while disabling the first and second lamps.

21. The flashlight of claim 15 wherein the first switch is an annular switch movable through a range of positions.

22. The flashlight of claim 21 wherein the flashlight is an elongated body having a front end at which the lamps are mounted and an opposed rear end, and wherein the first switch is a ring encircling the body adjacent to the front end.

23. The flashlight of claim 22 wherein the second switch is positioned at the rear end of the body.
