Description

Angle control circuit for light discharge tube of night vision goggles

The invention relates to a night vision goggle, in particular to an angle control circuit for a light discharge tube of the night vision goggle.

The development and exploration of human beings' night vision capabilities originated from military observation purposes. With the development of night vision device technology, the use of night vision devices has gradually evolved from air defense, land warfare, to aviation observation, and even to the present Development of stereoscopic virtual image technology, etc.

The main working principle of the night vision goggle is that the weak light reflected by the object is focused by the optical lens, and the image is imaged on the front receiver of the light discharge tube. The fluorescent screen translates into a bright image visible to the naked eye, and for use in near-total darkness, most night vision goggles have built-in infrared light, which can provide sufficient illumination at a certain distance in the infrared band invisible to the naked eye.

In addition, the current portable devices for night vision goggles, except for some fixed night vision goggles, such as night vision goggles for vehicles, generally night vision goggles are worn on the head of the personnel by means of a head-mounted device, so that personnel can easily actions and observations. However, when the personnel do not need to use the night vision goggles, they are used to moving the night vision goggles upwards. At this time, the angle of the light discharge tube of the night vision goggles will be upward. If you forget to turn off the power supply of the light discharge tube , in case there is a strong light from above, it will easily shorten the service life of the optical discharge tube, and even burn the optical discharge tube.

In view of this, the creator of this article deeply explores the problems faced by conventional night vision goggles. Based on years of research and development and manufacturing experience in related industries, we actively seek solutions, and after long-term hard research and development, this creation came into being.

The purpose of this creation is to provide an angle control circuit for the light discharge tube of night vision goggles, which can cut off the power of the light discharge tube in time to prolong the service life of the light discharge tube.

In order to achieve the above purpose, the angle control circuit for the light discharge tube of night vision goggles provided by this creation includes a battery, which provides the following required power; a power supply multi-stage selector switch, which is electrically connected to the battery , used to control the power on and off of the battery and the selection of functions; a voltage regulation circuit, which is electrically connected to the multi-stage selection switch of the power supply, to provide the following required voltage; a micro-processing unit, which is connected to the power supply A multi-section selector switch is electrically connected with the voltage regulating circuit for processing the received input signal and sending out an output signal; an optical discharge tube switch circuit is electrically connected with the voltage regulating circuit and the micro-processing unit for To control the power on and off of an optical discharge tube; an infrared light switch circuit is electrically connected to the voltage regulating circuit and the micro-processing unit to control the on and off of an infrared light power; an angle sensor is connected to the The voltage regulating circuit and the micro-processing unit are electrically connected to sense the angle when the night vision goggles are used. When the use angle leaves the forbidden angle area, the power supply of the optical discharge tube will be automatically restored.

The angle control circuit for the light discharge tube of night vision goggles provided by this creation, through the function of the angle sensor, enables this creation to cut off the power of the light discharge tube in time, and has the advantage of prolonging the life of the light discharge tube .
