Abstract

A lighting system, for example a portable light, can have at least two configurations that support outputting illumination in at least two different patterns. The lighting system can incorporate at least two light emitting diodes and at least two optics, for example two diffusing lenses or filters. In a first configuration, the light emitting diodes can emit light that provides illumination without incidence on the optics. In a second configuration, the light emitting diodes can emit light that is incident upon and controlled by the optics. Changing between the first and second configurations can move the optics into the respective light paths of the light emitting diodes.

First claim

What is claimed is:

1. A lighting system comprising:
a first member comprising:
a first light source operable to emit first light; and
a first light diffusing element; and

a second member comprising:
a second light source operable to emit second light; and
a second light diffusing element;

wherein the first member is moveable relative to the second member to provide at least a first position and a second position,
wherein in the first position, the first light exits the lighting system from the first member without substantial incidence on the second light diffusing element to generate a first illumination pattern and the second light exits the lighting system from the second member without substantial incidence on the first light diffusing element to generate the first illumination pattern,
wherein in the second position, the first light exits the lighting system from the second member by passing through the second light diffusing element to generate a second illumination pattern and the second light exits the lighting system from the first member by passing through the first light diffusing element to generate the second illumination pattern, and
wherein the first illumination pattern is different from the second illumination pattern.

2. The lighting system of claim 1 , further comprising a central member about which at least one of the first member and the second member rotate to provide the first position and the second position.

3. The lighting system of claim 2 , wherein the central member comprises a battery enclosure.

4. The lighting system of claim 3 , wherein the central member is sized for holding by hand.

5. The lighting system of claim 1 , wherein the first light source comprises at least one light emitting diode and the second light source comprises at least one other light emitting diode.

6. The lighting system of claim 5 , wherein the first light source further comprises a first focusing lens and the second light source further comprises a second focusing lens.

7. The lighting system of claim 1 , wherein in the first position, the first light emits from the lighting system without incidence on the first light diffusing element and the second light emits from the lighting system without incidence on the second light diffusing element.

8. The lighting system of claim 1 , wherein the first light diffusing element and the second light diffusing element are user changeable with respective filters.

9. A portable light comprising:
a central portion;
a first arm that extends from the central portion, the first arm being rotatable about the central portion and comprising:
a first aperture;
a first set of light emitting diodes (LEDs) disposed in the first aperture; and
a first optic disposed in the first aperture at a first position that is adjacent to and offset relative to the first set of LEDs; and

a second arm that extends from the central portion, the second arm being rotatable about the central portion and comprising:
a second aperture;
a second set of LEDs disposed in the second aperture; and
a second optic disposed in the second aperture at a second position that is adjacent to and offset relative to the second set of LEDs,
wherein the portable light is user changeable between a first configuration and a second configuration,
wherein when the portable light is changed from the first configuration to the second configuration where the first arm faces the second arm: (a) the first optic in the first aperture of the first arm is disposed in front of the second set of LEDs in the second aperture of the second arm such that light emitted by the second set of LEDs exits the portable light from the first arm by passing through the first optic to generate an illumination pattern, (b) and the second optic in the second aperture of the second arm is disposed in front of the first set of LEDs in the first aperture of the first arm such that light emitted by the first set of LEDs exits the portable light from the second arm by passing through the second optic to generate the illumination pattern.

10. The portable light of claim 9 , further comprising a compartment in the central portion that is sized to receive a battery for powering the first set of LEDs and the second set of LEDs.

11. The portable light of claim 9 , wherein the first optic comprises a first light diffusing element, and
wherein the second optic comprises a second light diffusing element.

12. The portable light of claim 9 , wherein the first optic comprises a first filter, and
wherein the second optic comprises a second filter.

13. The portable light of claim 9 , further comprising:
a first refractive lens disposed in front of the first set of LEDs; and
a second refractive lens disposed in front of the second set of LEDs.

14. A lighting system comprising:
a frame that comprises a first member and a second member;
a first light emitting diode mounted to the first member;
a first optic mounted to the first member;
a second light emitting diode mounted to the second member;
a second optic mounted to the second member,
wherein at least one of the first and second members is movable relative to the other of the first and second members so as to move the first optic in front of the second light emitting diode such that light emitted by the second light emitting diode exits the lighting system from the first member by passing through the first optic in the first member and the second optic in front of the first light emitting diode such that light emitted by the first light emitting diode exits the lighting system from the second member by passing through the second optic in the second member.

15. The lighting system of claim 14 , wherein the first optic comprises a first diffusing lens, and
wherein the second optic comprises a second diffusing lens.

16. The lighting system of claim 14 , wherein the frame further comprises a central portion,
wherein the first member extends from the central portion, and
wherein the second member extends from the central portion.

17. The lighting system of claim 14 , wherein the frame further comprises a central portion,
wherein the first member comprises a first arm that extends from the central portion and that is rotatable about the central portion, and
wherein the second member comprises a second arm that extends from the central portion and that is rotatable about the central portion.

18. The lighting system of claim 14 , wherein the lighting system comprises a portable light.

19. The lighting system of claim 14 , wherein the first optic comprises a first filter, and
wherein the second optic comprises a second filter.
