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.
