Abstract

An apparatus for generating light-based special effects viewable in daylight. The apparatus includes a barrel with opaque sidewalls defining an interior space accessible via a muzzle. The apparatus includes a light element positionable within the interior space and further includes a light positioning assembly. The apparatus includes a trigger element operable to receive user input to initiate operations of the light element and the light positioning assembly. A controller is provided that responds to the user input to operate the light positioning assembly to first move the light element out of the interior space through the muzzle and to second retract the light element back into the interior space. The controller concurrently operates the light element to generate the light when the light element is moved out of the interior space and to terminate the generating of the light when the light element is retracted back into the interior space.

First claim

I claim:

1. An apparatus for generating light-based special effects viewable in daylight and other brightly lit settings, comprising:
a barrel with opaque sidewalls defining an interior space accessible via a muzzle;
a light element positionable within the interior space, the light element being operable to selectively output light;
a light positioning assembly;
a trigger element operable to receive user input to initiate operations of the light element and the light positioning assembly; and
a controller responding to the user input to operate the light positioning assembly to first move the light element at least partially out of the interior space through the muzzle and to second retract the light element back into the interior space, wherein the controller concurrently operates the light element to generate the light when the light element is moved out of the interior space and to terminate the generating of the light when the light element is retracted back into the interior space.

2. The apparatus of claim 1 , wherein the operations of the light positioning assembly are both performed in less than 1 second.

3. The apparatus of claim 1 , wherein the light positioning assembly comprises a pneumatic actuator operable to move the light element out of the interior space of the muzzle and a spring-based return element to retract the light element back into the interior space.

4. The apparatus of claim 1 , wherein the light positioning assembly comprises an electric actuator operable to move the light element out of the interior space of the muzzle and a return element to retract the light element back into the interior space.

5. The apparatus of claim 1 , wherein the light positioning assembly extends the light element out a distance of at least 2 inches past the muzzle when the light element is moved out of the interior space of the barrel.

6. The apparatus of claim 1 , wherein the light element comprises a 1000-Lumen or greater light source.

7. The apparatus of claim 6 , wherein the light element comprises a white light emitting diode (LED) with a rating in the range of 1000 to 5000 Lumens.

8. The apparatus of claim 6 , wherein the light element further comprises an enclosure housing the light source and wherein the enclosure is transparent-to-translucent to light and has a length exceeding a length of excursion of the light element from the muzzle.

9. The apparatus of claim 8 , wherein the interior space is defined by inner surfaces of the sidewalls of the barrel, wherein the inner surfaces are colored black, and wherein exterior surfaces of the enclosure are painted or dyed with transparent black paint or dye.

10. The apparatus of claim 8 , wherein a colored lens or gel is applied to one or more interior surfaces of the enclosure to color the light output by the light source.

11. An apparatus for providing flashes of light in a repeatable manner, comprising:
a barrel with an interior space accessible through an open end of the barrel;
a light element positioned in the interior space, the light element comprising a light source and an enclosure housing the light source;
an actuator attached to a first end of the enclosure operable for moving the enclosure between a first position wholly within the interior space and a second position with at least a second end opposite the first end a distance from the open end of the barrel; and
a controller operating the actuator to move the light element from the first position to the second position and back to the first position,
wherein the controller concurrently operates the light source to generate light when the enclosure is moved to the second position and to halt generation of the light when the enclosure is moved to the first position, and
wherein the actuator moves the enclosure from the first position to the second position and back to the first position in less than one second.

12. The apparatus of claim 11 , wherein the actuator comprises a pneumatic actuator or electric actuator operable to move the enclosure out of the interior space through the open end of the barrel and a spring-based return element to retract the enclosure from the second position to the first position.

13. The apparatus of claim 11 , wherein the enclosure travels through an excursion length in the range of 2 to 6 inches when moved from the first position to the second position.

14. The apparatus of claim 11 , wherein the light element comprises a 1000-Lumen or greater light source.

15. The apparatus of claim 14 , wherein the light element comprises a white light emitting diode (LED) with a rating in the range of 1000 to 5000 Lumens.

16. The apparatus of claim 11 , wherein the enclosure is transparent-to-translucent to light and wherein exterior surfaces of the enclosure are painted or dyed with transparent black paint or dye.

17. The apparatus of claim 16 , wherein a colored lens or gel is applied to one or more interior surfaces of the enclosure to color the light output by the light source.

18. An apparatus for generating light-based special effects viewable in daylight and other brightly lit settings, comprising:
a barrel with sidewalls defining an interior space accessible via a muzzle;
a light element positionable within the interior space;
a light positioning assembly; and
a controller responding to user input to operate the light positioning assembly to first move the light element at least partially out of the interior space through the muzzle and to second retract the light element back into the interior space,
wherein the controller concurrently operates the light element to generate the light when the light element is moved out of the interior space and to terminate the generating of the light when the light element is retracted back into the interior space,
wherein the light element comprises light emitting diode (LED) with a rating in the range of 1000 to 5000 Lumens,
wherein the light element further comprises an enclosure housing the light source, and
wherein exterior surfaces of the enclosure are painted or dyed with transparent black paint or dye.

19. The apparatus of claim 18 , wherein the LED is a white LED with a rating in the range of 1000 to 5000 Lumens and wherein a colored lens or gel is applied to one or more interior surfaces of the enclosure to color the light output by the light source.

20. The apparatus of claim 18 , wherein the operations of the light positioning assembly are both performed in less than 1 second and wherein the light positioning assembly comprises a pneumatic or electric actuator operable to move the light element out of the interior space of the muzzle and a spring-based return element to retract the light element back into the interior space.
