Abstract: An automatic light-adjusting structure for a red dot sight includes a sight body, a lens frame disposed at the upper part of the sight body, a reflecting lens, a light sensor and a processing unit. The reflecting lens is configured for transmitting target light rays to a receiving end of the light sensor, and the light sensor is configured for detecting the brightness of the target light rays and transmitting brightness data to the processing unit; the processing unit is configured for analyzing the brightness data and adjusting the brightness of a light source in the sight body according to an analysis result. The brightness of the light source (LED) is adjusted according to the brightness of the target light rays, thus achieving the purpose of self-adaptive adjustment, and the optimal visual experience is provided.

Abstract: A red dot sight includes a sight body. A lens frame is arranged on a front end of the sight body, and a lens is arranged in the lens frame; a lamp holder is arranged in the sight body, a Light Emitting Diode (LED) lamp is arranged on the lamp holder, an adjustment mechanism is arranged in the sight body, a windage adjustment screw and a gravity adjustment screw are arranged on an outer side of the sight body, and the windage adjustment screw and the gravity adjustment screw are connected to the lamp holder through the adjustment mechanism; and a battery jar is formed in a side surface of the sight body. Through the reasonable design of the structure, a clearance between components of a mechanical structure is eliminated, and the smoothness of adjustment and the structural accuracy are improved.
