Optical sighting device

Abstract

An optical sighting device includes a light source module, a base and a reflector. The light source module includes a light source and a substrate on which the light source is disposed. The base includes a first end and a second end. The light source module is disposed at the base, and the light source of the light source module faces the first end. The reflector is disposed at the first end. The illumination light emitted by the light source corresponds to the reflector within an illumination angle range, and the illumination light within the illumination angle range is reflected by the reflector to form a reflected light. The base further includes a light emitting structure. The portion of the irradiation light outside the irradiation angle range is directed toward the light emitting structure. The base further includes a light outgoing structure having a through hole. The irradiation light not reflected by the reflector propagates towards the through hole, and a portion of the irradiation light travels away from the base via the through hole.
