Laser dazzling helmet

Abstract

The invention discloses a laser dazzling helmet, and belongs to the field of security protection and the photoelectric technology. The helmet comprises a helmet body, at least one laser source, a first LED array, a second LED array, a protective mask and a power supply. The laser source is arranged on the side of the helmet body, the first LED array and the second LED array are concentrically arranged in the front of the helmet body, the first LED array is composed of green light or red light LEDs, the second LED array is composed of white light LEDs, the protective mask and the helmet body are movably connected, an attenuation film is attached to the surface of the protective mask, the laser source, the first LED array and the second LED array 4 are connected with the power supply through wires, and the power supply is fixedly connected with the rear side of the helmet body. Long-distance dazzling is carried out on mobs by means of the laser source so that the mobs can lose vision temporarily, short-distance dazzling is carried out through the LED arrays so that the mobs can not look at the police directly or effective attack, and the police can quickly attack or guard.

Description

technical field [0001] The invention relates to an anti-riot device, in particular to a helmet, which belongs to the field of security and photoelectric technology. Background technique [0002] The function of a large number of police anti-riot equipment currently equipped in our country is too single, such as simple shields, batons, and anti-riot forks. [0003] On March 1, 2014, the appalling Kunming massacre occurred in Kunming, my country. Five thugs with knives killed more than 180 innocent citizens in a relatively short period of time. Among them, a deputy director of a police station died heroically in the process of using a riot fork to resist riots, highlighting the inadequacy of our country's police anti-riot equipment in fighting sudden violent terrorist incidents. [0004] Using visible light to dazzle mobs and make them temporarily blind and lose their attack power is currently internationally recognized as a method of anti-riot with the least harm to human bo...

AI Technical Summary

Problems solved by technology

[0005] Existing dazzling helmets use high-power light-emitting devices such as strong lights and strobe lights or LED arrays as dazzling light sources, which have the advantages of large weight, high power consumption, and poor battery life; and poor long-distance dazzling effects

Mainly, high-voltage arc lamps such as mercury lamps and xenon lamps are used as light sources for high-voltage lamps and flashing lamps. However, the luminous efficiency of arc lamps is very low, and the required power supply is large, which leads to high power consumption of traditional dazzling anti-riot helmets. Poor; at the same time, the light divergence angle of strong lights, flashing lights and LEDs is large, and the luminous intensity of a single LED is not enough to require LED arrays or area arrays to achieve the required light intensity, so a large reflective bowl or beam shaping system is required Converging light, this traditional optical structure will cause a loss of light energy of more than 10 meters and the dazzling effect is not good; the overall volume and structure of the arc lamp is large, resulting in the heavy weight of the traditional dazzling helmet, which is not easy to wear for a long time. Helmets can cause neck injuries to users

Therefore, the practicability of traditional blinding helmets is poor and fails to be equipped in large quantities
