Abstract

A light for mounting on an implement is provided. In particular, a light configured to be releasably attached to a firearm is provided. The light includes first and second light elements. A selector switch is operable to select which of the two light elements is energized when a primary switch is actuated.

First claim

The invention claimed is:

1. A portable light mountable on a mounting rail on a firearm having a trigger guard around a trigger, wherein the trigger has an axial length, comprising:
a housing configured to house a source of electrical energy;
a light assembly, comprising:
a first light element;
a second light element;
a reflector for focusing light of at least one of the first and second light elements;
wherein the light assembly has an outer surface defining a perimeter of the light assembly;

a mounting assembly connected with the housing, wherein the mounting assembly is operable to releasably connect the housing to the mounting rail of the firearm;
an actuation switch mounted on a first end of the housing so that when the light is mounted on the firearm the actuation switch has an actuation surface adjacent a trigger guard of the firearm so that the actuation surface is less than the axial length of the trigger away from the trigger guard;
a selector switch for selecting which of the first and second light elements is energized when the actuation switch is actuated, wherein the selector switch is a non-contact switch comprising an actuator and a sensor in a switching compartment sealingly separated from the actuator;
wherein the selector switch comprises a magnetic element connected with the actuator and a plurality of sensors for providing an output voltage in response to being in proximity with the magnetic element; and
wherein when the actuator is in a first position, a first of the sensors provides an output voltage while a second of the sensors does not provide an output voltage; and wherein when the actuator is in a second position, a second of the sensors provides an output voltage while the first sensor does not provide an output voltage.

2. The light of claim 1 wherein the light comprises a processor receiving signals from the sensors and controlling which of the first and second light elements is energized in response to which sensor provides an output voltage.

3. The light of claim 1 wherein the selector switch comprises a sealed switch compartment to impede ingress of fluid into the switch compartment from outside the light, wherein the plurality of sensors is within the switch compartment and the actuator is outside the switch compartment.

4. The light of claim 1 wherein the selector switch is positioned on a lower surface of the housing.

5. The light of claim 4 wherein the selector switch is configured so that the selector switch does not substantially protrude radially outwardly beyond the perimeter of the light assembly.

6. The light of claim 5 wherein the selector switch is configured so that the outer surface of the selector switch terminates within the perimeter of the light assembly.

7. The light of claim 1 wherein the selector switch is positioned rearwardly of a midpoint of the length of the light.

8. The light of claim 1 wherein light from the first light element projects forwardly along a first axis and the actuation switch is actuable by displacing the actuation surface in a first actuation direction that is transverse the first axis and the selector switch is actuable by displacing an actuator in a second actuation direction transverse either the first axis or the first actuation direction.

9. The light of claim 8 wherein the second actuation direction is transverse the first axis and the first actuation direction.

10. The light of claim 1 wherein the mounting assembly and actuation switch are configured so that when the light is mounted on the firearm the actuation switch extends rearwardly to overlap a portion of the trigger guard.

11. The light of claim 1 wherein the actuation switch is configured so that the actuation switch straddles the trigger guard when the light is mounted on the firearm.

12. The light of claim 1 wherein the second light element is a laser.

13. A portable light mountable on a mounting rail of a firearm, wherein the firearm has a trigger having an axial length and a trigger guard around the trigger, wherein the light comprises:
a housing configured to house a source of electrical energy;
a light assembly connected with a forward end of the housing, comprising:
a first light element;
a second light element;
a reflector for focusing light of at least one of the first and second light elements;
wherein the light assembly has an outer surface defining a perimeter of the light assembly;

a mounting assembly connected with the housing, wherein the mounting assembly is operable to releasably connect the housing to the mounting rail of the firearm;
an actuation switch mounted on a rearward end of the light so that when the light is mounted on the firearm the actuation switch has an actuation surface adjacent a trigger guard of the firearm such that the actuation surface is spaced from the trigger guard less than the axial length of the trigger;
a selector switch for selecting which of the first and second light elements is energized when the actuation switch is actuated wherein the selector switch comprises a sealed switch compartment to impede ingress of fluid into the switch compartment from outside the light, wherein the selector switch comprises an actuation surface that does not protrude radially outwardly beyond the perimeter of the light assembly.

14. The light of claim 13 wherein the selector switch is configured so that the outer surface of the selector switch terminates within the perimeter of the light assembly.

15. The light of claim 13 wherein the selector switch is positioned rearwardly of a midpoint of the length of the light.

16. The light of claim 13 wherein the selector switch is positioned on a lower surface of the housing opposite from the mounting assembly.

17. The light of claim 13 wherein light from the first light element projects forwardly along a first axis and the actuation switch is actuable by displacing the actuation surface in a first actuation direction that is transverse the first axis and the selector switch is actuable by displacing an actuator in a second actuation direction transverse either the first axis or the first actuation direction.

18. The light of claim 17 wherein the second actuation direction is transverse the first axis and the first actuation direction.

19. The light of claim 13 wherein the mounting assembly and actuation switch are configured so that when the light is mounted on the firearm the actuation switch extends rearwardly to overlap a portion of the trigger guard.

20. The light of claim 13 wherein the actuation switch is configured so that the actuation switch straddles the trigger guard when the light is mounted on the firearm.

21. The light of claim 13 wherein the second light element is a laser.

22. The light of claim 13 wherein the actuation switch is operable to switch the light assembly between an ON condition and an OFF condition.

23. A portable light mountable on a mounting rail of a firearm, wherein the firearm has a trigger guard surrounding a trigger, and wherein the light comprises:
a housing configured to house a source of electrical energy, wherein the housing has a forward end and a rearward end;
a light assembly at the forward end of the housing, comprising:
a first light element;
a second light element;

a mounting assembly connected with the housing, wherein the mounting assembly is operable to releasably connect the housing to the mounting rail of the firearm;
an actuation switch on the re
