BACKGROUND
1. Field
The disclosure of the present patent application relates to emergency response devices, and particularly to an LED light ball for emergency responders.
2. Description of the Related Art
In general, emergency response devices are used by emergency responders to distract, disable, or tag potential criminal perpetrators (perps). Some of these devices are in the form of a projectile and include distraction balls that emit a single beam of light that spins with the ball and thereby distracts the subject. Other projectile devices used by emergency responders include a ball that hits the perp and releases a dye/odor pack to later identify the perp. Other light ball devices are activated by vibration and can therefore illuminate before reaching the area of the perp, thereby alerting them before illuminating them. Some previous devices include timers and can therefore turn themselves off prior to the situation being resolved.
Thus, an LED light ball for emergency responders solving the aforementioned problems is desired.
SUMMARY
The LED light ball for emergency responders is activated upon contact after being fired from a launcher to illuminate an area of interest, such as a potential crime scene. The ball includes a clear polymeric, spherical, slightly flexible outer casing, and a clear rectangular inner casing having a circuit board mounted therein. A plurality of rig rods extend through the inner casing and include curved heads that are in close proximity to the inner surface of the spherical outer casing. Upon impact, the outer casing flexes and pushes against one of the curved heads and pushes its associated rig rod inward, thereby closing a contact that triggers a control circuit to connect a positive terminal of an internal battery (or batteries) to a plurality of light emitting diodes (LEDs). The LEDs can, for example, provide 900 lumens per light or more, equaling 2700 lumens or more in total with three LEDs. Once switched on, the control circuit maintains the LEDs lit and completely fills the immediate area with light. The light may be provided as a solid ball of light or separate beams of light, and can either be illuminated continuously or in a strobe-like fashion.
While the LED light ball may be thrown, for greater range the LED light ball may fired from a conventional 40 mm launcher that has a cylinder loaded with compressed air or carbon dioxide to launch other emergency response projectiles (such as bean bags, etc.). The outer casing may be in two hemispherical pieces that are fused together to house the remaining components therein. In a further embodiment, the LED light ball is in the form of a two-piece elongated cylinder with rounded ends. A first front piece has a larger diameter that the second rear piece and slides over the second piece upon impact, thereby activating the above-described rig rods.
These and other features of the present subject matter will become readily apparent upon further review of the following specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The LED light ball for emergency responders, designated generally as 10 in the drawings, is shown in FIG. 1, having been activated upon contact after being launched by an emergency responder ER from a launcher L to illuminate an area of interest P, such as a potential crime scene. While the LED light ball may be thrown, for greater range the LED light ball is fired from a launcher that has a cylinder loaded with a compressed gas, such as compressed air or carbon dioxide, to launch emergency response projectiles. The details of the LED light ball 10 are best seen in FIGS. 2-4. The light ball includes a clear polymeric, spherical, slightly flexible outer casing 20, similar to hollow, transparent polymer toy balls. As with the toy balls the outer casing 20 is resilient and yields upon impact, but returns to its spherical shape thereafter. The outer casing 20 may be in two hemispherical pieces that are fused together to house the remaining components therein. A rectangular, clear inner casing 40 (FIG. 4) is mounted within the outer casing 20, and a printed circuit board 22 is mounted within the inner casing 40. The circuit board 22 includes a plurality of conductive traces 28 (shown in FIGS. 2 and 3) for making the electrical connections, as described below with respect to the block diagram of FIG. 5. It should be noted that the traces 28 shown in FIGS. 2-3 are for illustrative purposes only and are not intended to represent the actual traces on the circuit board 22. A plurality of rig rods 21 extend through the inner casing 40 and include curved heads 23 that are in close proximity to the inner surface 25 of the spherical outer casing 20. Upon impact with a surface, the outer casing 20 flexes and pushes against one of the curved heads 23 (depending on the area of impact on the spherical outer casing 20) and pushes its associated rig rod 21 inward, thereby closing an electrical contact (not shown). The light ball 10 also includes a plurality of high-power LEDs 24 mounted on or near the circuit board 22, capable of producing 2700 lumens or more in total, one or more batteries 30, for powering the light ball, and an integrated circuit or latch 26. The rig rods 21 are, in essence, momentary switches connected in parallel and having elongated contact pins that are activated by contact of the ball 10 with an object applying sufficient pressure to the head of at least one contact pin to momentarily apply power to the LEDs 24. The rig rods are spaced radially so that contact at any angle is sufficient. Once turned on, the latch 26 keeps the LEDs 24 turned on until power is dissipated or disconnected.
FIG. 5 shows a block diagram 50 of the electrical circuit of the LED light ball for emergency responders 10. The positive electrode of the battery 30 is connected to one of the contacts of each of the rig rods 21 and to a first terminal of the circuit or latch 26 by first wire and/or trace 52. The other contact of each of the rig rods 21 is connected to a second terminal of the circuit or latch 26 by a second wire and/or trace 54. A third terminal of the integrated circuit or latch 26 is connected to the positive lead of all of the LEDs 24 by a third wire and/or trace 56. The negative electrode of the battery 30 is connected to a fourth terminal of the circuit or latch 26 and to the negative lead of all of the LEDs 24 by a fourth wire and/or trace 58. The contacts for the rig rods 21 are wired in parallel, such that a single activated rig rod triggers the integrated circuit or latch 26 to connect the positive terminal of the internal battery (or batteries) to all of the LEDs. The LEDs, for example, can provide 900 lumens per light or more equaling 2700 lumens or more in total with three LEDs. The circuit 26 may be a simple latching micro-relay that maintains the LEDs lit once triggered by one or more of the rig rods 21. In other embodiments, the circuit 26 is a programmable integrated circuit that can provide strobe-like, light pattern flashing or other lighting functions. Furthermore, the rig rods 21 are only one way of triggering the circuit 26, and other devices or circuits for triggering the circuit 26, such as an accelerometer, are contemplated.
A further embodiment of the LED light ball (or projectile) 60 is shown in FIG. 6. The LED light projectile 60 has an outer casing in the form of a two-piece elongated cylinder with rounded ends. The LED light projectile 60 includes all the components as described with respect to the first embodiment of FIGS. 1-5. The first, front piece 64 is in the form of a short cylinder with a rounded closed end 68 and an open second end. The second, rear piece is in the form of an elongate cylinder 62 with a rounded closed end 66 opposite to the rounded closed end 68 of the first, front piece 64 and an open second end. The first front piece 64 has a larger diameter than the second rear piece 62 and slides over the second piece 62, the open second end of the second piece 62 being frictionally inserted into the open end of the first front piece 64. The previously described rig rods 21 are disposed within the projectile 60 such that their heads 23 are in close proximity to an inner surface of the rounded closed end 68. Upon impact with a surface, the front piece 64 is driven backwards against the rig rods 21, thereby activating the LEDs 24, as described above with respect to the embodiment of FIGS. 1-5. Unlike the LED light ball 10, the LED light projectile 60 is less likely to continue rolling past the area of interest.
It is to be understood that the LED light ball for emergency responders is not limited to the specific embodiments described above, but encompasses any and all embodiments within the scope of the generic language of the following claims enabled by the embodiments described herein, or otherwise shown in the drawings or described above in terms sufficient to enable one of ordinary skill in the art to make and use the claimed subject matter.
