Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit and priority of U.S. Provisional Application No. 60/920,633 filed Mar. 28, 2007 entitled Tactical Lighting System and which is incorporated by reference herein in its entirety.

BACKGROUND AND SUMMARY

The present disclosure relates to portable lights which can be used to stun, temporarily blind and disorient an individual. Such lights can be used in police, military and civilian applications where it is necessary to distract, temporarily disorient and even disable a person without causing permanent harm to the person or property.
The portable lights can be used as a supplement to or substitute for conventional flash grenades. A common problem with flash grenades is that they are incendiary and have been known to cause fires as well as burns and other bodily injuries. The portable light disclosed herein can be a battery-operated high-intensity light. One type of light source which has been found to be effective is a white light-emitting-diode (LED).
Because an LED light source is derived from low temperature semiconductors, there is no chance of starting a fire or causing burns. Moreover, the battery-powered light can be economically reused many times, if desired. This is particularly useful when practicing various tactics using the lights.
While the lights are adapted to be thrown by hand, either individually or in sets or groups of two or more, the lights may be projected by any other suitable means from a device as simple as a slingshot to a long-range gas (CO₂)-powered launcher, such as used to fire paint-balls. Spring-powered launchers and gunpowder-powered launchers can also be used to fire individual lights, or groups of lights.
Various other objects, features and attendant advantages of the present disclosure will be more fully appreciated as the same becomes better understood from the following detailed description.

DESCRIPTION OF THE EMBODIMENTS

As seen in FIG. 1, a light 10 is constructed with a substantially spherical housing 12 to allow the light to roll and wobble across a floor or other surface. A clear, transparent lens or light cover 14 having an outer spherical surface portion 16 (FIG. 2) extends over one or more light sources 18 and forms a portion of housing 12. Light sources 18 can be electric lights such as incandescent lamps or solid state lamps such as LEDS.
The housing 12 includes a first or bottom portion 20 and a second or top portion 22, as seen in FIGS. 2 through 6. The bottom portion 20 includes a depressable spring-biased switch actuator 24, which can be selectively depressed and released to turn the light sources 18 on and off via snap-action switch 26.
One or more batteries, such as button batteries 30, are nested within a pocket 32 (FIG. 4) to engage an electrical contact 34 on switch 26. A second electrical contact 36 extends upwardly along the inner sidewall 38 of a tubular wall 48. Wall 48 includes external screw threads 50 (FIG. 3) which mate with screw threads 52 (FIGS. 5 and 6) formed in the inner wall 54 of the top potion 22 of housing 12. An elastomeric O-ring 56 is provided around the base of wall 48 to provide a water-tight seal between the bottom and top housing portions 20, 22.
The top housing portion 20 further includes a parabolic mirror 60 centered around the light sources 18. An insulator plate 62 supports the light sources 18. A first electrical contact 64 is connected to one lead of each light source. A circular slip ring 66 is seated on an insulated plastic tubular wall 68 to make electrical contact with the other lead of each light source 18 and with the second electrical contact 36 on the bottom housing portion 20.
In this manner, an electrical circuit is completed between the light sources 18 and the switch 26 when the asymmetrical bottom and top portions 20, 22 are screwed together to form spherical housing 12. A parting line 70 (FIG. 7) is thus formed between the upper and lower housing portion 20, 22. The light sources are selectively operated via push button on-off switch actuator 24.
As seen in FIG. 7, the light 10 is designed such that at rest, the light sources 18 will project a light beam 72 upwardly at an angle from the surface 74 upon which the light 10 sits. This is accomplished by designing the center of gravity 78 (FIGS. 2 and 7) of light 10 in the lower hemisphere of housing 12.
In use, one or more lights 10 may be turned on by depressing the switch actuator plunger 24. The lights 10 may then be thrown by hand into a room so that they roll, bounce, slide, spin and wobble across the floor 74. As seen in FIG. 8, the light beams 72 produce a random moving pattern of light as indicated by the directional arrows 78. It has been found that this random pattern of light can cause temporary blindness and disorientation to a degree which can immobilize or incapacitate a person.
A group of lights 10 is shown in FIG. 9 nested in series in a magazine pouch 80. Pouch 80 can be formed of rigid or flexible material. A releasable cover flap 82 is provided to allow for selective access to the lights 10 snugly stored in the magazine pouch 80. A belt loop or clip 84 can be provided for Conveniently carrying one or more magazines of lights 10 on one's person.
The lights 10 may be loaded in a linear series into the magazine pouches 80 with a light friction fit so that the actuators 24 are aligned with openings through the walls of pouch 80 or with indicia on pouch 80. This allows a user to turn on the lights 10 through these operating portions of the pouch while the lights are still in their magazine pouches 80. Openings in the pouch sidewall are required for rigid pouches, but simple indicia markings can be provided on flexible fabric pouches to indicate the location of the switch actuators 24 within the pouches so as to allow for depression of actuators 24 through the fabric, as represented by directional arrows 86 in FIG. 9.
Once turned on within the pouch 80, the brightly illuminated lights 10 cannot be seen outside of the pouch, but can be thrown by a user directly out of the pouch 80 and then become visible. In this manner, a number of lights 10 can be deployed with a single toss or throw. A sweeping arcuate horizontal swing or throw can release the lights 10 from pouch 80 in a sweeping series of trajectories as shown in FIG. 12. As the lights 10 bounce off a wall 88 or off a piece of furniture, the light beams 72 can be particularly effective in disorienting a person in the room. The pouch 80 is typically retained in the hand of the user after the lights 10 are hurled from the pouch and can thus be refused, as can the lights 10.
While hand throws are effective for short to medium range use of lights 10, a mechanical projector can be used for longer range applications as well as short and medium range applications. For example, a sling or slingshot 90 (FIG. 10) can be used to project one or more lights 10 over longer distances and at higher velocities than those achievable by hand. In this case the lights 10 can be shot through upper and lower windows 92 of a building 94. Even exotic instruments such as crossbows can be easily adapted to project lights 10.
Lights 10 can also be projected by spring, compressed gas or gunpowder using a suitable device such as a handgun 96 (FIG. 11), a rifle or shotgun 98 (FIG. 13), or a cannon or mortar 100 (FIG. 16). In FIG. 13, a group of lights 10 can be released with a single shot or individually in a series of shots. Compressed gas, such as provided in carbon dioxide cylinders 102 (FIG. 13), can be used effectively in this application.
While spherical lights 10 have been described, it should be noted that virtually any shape of light can be used. For example, a somewhat bell-shaped housing 12 (FIG. 14) can be used effectively, as can a cigar-shaped housing 12 (FIG. 15). In FIG. 15, two sets of light sources are provided, one at each end of housing 12.
There has been disclosed heretofore the best embodiments of the disclosure as presently contemplated. Obviously, numerous modifications and variations of the present disclosure are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the embodiments may be practiced otherwise than as specifically described herein.
While the invention is susceptible to alternative constructions, certain embodiments thereof have been described above in detail. It should be understood, however, that there is no intention to limit the disclosure to the specific form or embodiments disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the disclosure, as defined in the appended claims.
