Abstract

An apparatus produces a “dazzling” effect: disorientation and temporary and fully reversible blindness in subjects for the purpose of threat deterrence in both civilian law enforcement and military engagements without the use of lasers. A plurality of light emitting diodes (LEDs) capable of intense illumination is provided. Light emitted by each LED is pulsed and focused by reflective optics to produce a pulsed beam of sufficient intensity that the combined effect of the beams from the LEDs induces dazzling in subject viewers in the target range. Further included in or ancillary to the invention are a power source for powering the LEDs a signal source and controller for controlling their illumination and pulsing, and a shield suitable for protecting a user against projectiles.

Claims

1. A non-lethal weapon apparatus for subduing a viewing subject in a target area, comprising;

a plurality of high intensity light emitting diodes emitting beams of high intensity light directed to a target area when current is provided to illuminate the light emitting diodes and

at least one dedicated light emitting diode driver means for providing pulsed current to illuminate the light emitting diodes in high intensity light pulses, whereby the high intensity light pulses from the light emitting diodes are directed to the target area to produce a dazzling effect in a viewing subject.

2. A weapon according to claim 1, wherein the plurality of light emitting diodes forms an array, the array further comprising optical means for directing the beams of high intensity light emitted from the array to the target area.

3. A weapon according to claim 1, further comprising a power supply providing electrical power to the light emitting diodes and the driver means.

4. A weapon according to claim 1, further comprising a signal source providing signals to the driver means, wherein the driver means provides the pulsed current to illuminate the light emitting diodes in high intensity light pulses in response to signals from the signal source.

5. A weapon according to claim 1, further comprising a high intensity directed acoustical device.

6. A dazzler shield for subduing a viewing subject in a target area, comprising

a shield surface having a user side and a target side, the shield surface affording protection on the user side from objects originating on the target side;

a plurality of high intensity light emitting diodes emitting beams of high intensity light directed from the target side to a target area when current is provided to illuminate the light emitting diodes and

at least one dedicated light emitting diode driver means for providing pulsed current to illuminate the light emitting diodes in high intensity light pulses, whereby the high intensity light pulses from the light emitting diodes are directed to the target area to produce a dazzling effect in a viewing subject.

7. A dazzler shield according to claim 6, wherein the shield is adapted for handheld use.

8. A dazzler shield according to claim 6, wherein the shield surface is comprised of transparent polymer material.
