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.
