With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved light communication apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, the light communication apparatus 10 of the instant invention includes a primary housing 11 having a housing pistol grip 12 configured at an oblique angle relative to the primary housing, with earphones 13 mounting microphone 14 mounted by means of a communication cable to the pistol grip portion of the housing structure, with a first switch 15 configured as a trigger 15 mounted within a trigger guard loop 16 directed about the primary housing 11. A light transmission tube 17 is coaxially aligned with an oriented in a coextensive relationship relative to a light receiving tube 18 projecting through a forward end of the primary housing 11, with the light transmission tube 17 mounting a first lens 19 and the light receiving tube 18 mounting a second lens 20, with each lens at a free distal end of the respective light and receiving tube structure 17 and 18 respectively. A second switch 21 is mounted at an intersection of the primary housing of the pistol grip configured as an on/off switch 21 relative to the operative circuitry employed by the invention mounted within a control circuit housing 35 within the pistol grip 12 in adjacency to a second battery 24 relative to first batteries 23 mounted within the primary housing 11 in electrical communication with an illumination transmitter bulb 25 positioned within a concave reflector 26 within the light transmission tube 17.

To prevent ambient light interference entering the second lens 20 and for effecting shielding of the light transmission tube 17, a unitary extension housing 34 is provided, as indicated in FIG. 6, having a first extension tube 32 parallel to and coextensive with a second extension tube 33. The first and second extension tubes includes respective first and second magnetic strips 29 and 31 respectively arranged for securement to respective first and second ferrous bands 28 and 30 mounted to the respective transmission receiving tubes 17 and 18 adjacent the respective first and second lenses 19 and 20 to permit the ease of mounting of the extension housing 34 relative to the primary housing 11.

The control circuit housing 35, as indicated in FIG. 5, includes the second battery 24 parallel to the capacitor, whereupon actuation and closure of the second switch 21. Upon closure of the first switch 15, power is applied to the integrated circuits indicated as U-1 and U-2 respectively. The earphones 13 and the microphone 14 are provided wherein the earphones 13 are in operative communication with the integrated circuit U-1 through the capacitor 1 and the capacitor 6 to provide for proper charging of the capacitors to provide for transmission to the earphones 13, with the capacitor 1 arranged in series between the integrated circuit U-1 and the earphones 13, while the capacitor 6 is oriented in a parallel relationship relative to the earphones 13 and integrated circuit U-1. The FIGS. C-3 and C-4 respectively are operatively connected to the integrated circuits U-1 and U-2 respectively and are arranged to charge up for actuation of the earphones and microphone circuitry. The integrated circuits U-1 and U-2 respectively are provided for the respective receiving and transmission functions. Should switch 15 or S-1 be opened, then transmission to the earphones 13 through the integrated circuit U-1 is availed as the light cell or light receiving grid 27 is arranged in operative communication with the integrated circuit U-1 to receive such transmission. The switch 1 or trigger 15 is closed, power is directed to the integrated circuit U sub 2 in operative communication with a microphone 14 such that energy sensed to the integrated circuit U-2 will cause modulation pulses to be sent out to the transformer T-1. The transformer will expand and collapse to modulate the bulb 25 at much higher intensity and that signal of a pulsating light will be transmitted to another individual's receiving tube 18 of an identical unit, as indicated by the FIG. 4 for example. Further, the light cell 27 or receiver grid 27 receiving pulses from another individual's unit or light transmission tube 17 is such that the receiving pulses of light are converted to pulsating inputs to the reception integrated circuit U sub 1 and are demodulated to produce a signal that is audible and directed to the earphones 13. The resistors R sub 1, R sub 2, R sub 3, and R sub 4 are provided to control voltage through the transmission lines as required for proper operation of the invention. B1 or batteries 23 are typically two 1.5 volt cells, with the battery B sub 2 of a nine volt construction. The capacitors 2, 3, 4, and 6 are ten micro-farad electrical capacitors, wherein capacitors 1 and 5 are 220 micro-farad electrical capacitors. The diode D-1 arranged in parallel relative to the switch 2 is illuminated upon closure of the switch 2 to indicate such closure. The integrated circuits U-1 and U-2 are of LN-386 audio amplifier types, with the transformer of an audio output configuration. The solar or light cell 27 is typically of a 0.5 voltage capacity, as employed, and the resistors 1 and 2 are of 1-K ohm construction, while the resistors 3 and 4 are of a 330 ohm configuration.

As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
