US12742956 - Dual-light-source red dot sight

The dual-light-source red dot sight features a housing with two openings and a through channel containing two light source assemblies that emit distinct light beams, along with a light adjustment module for controlling the emitted light. This design incorporates various optical components, including collimating lenses, mirrors, and a beam splitter, to enhance visibility and targeting accuracy for the user.

Claim 1

1 . A dual-light-source red dot sight, comprising: a housing having a first opening at one end and a second opening at the other end, with a through channel formed inside the housing and extending from the first opening to the second opening; a first light source assembly and a second light source assembly mounted in the through channel and arranged one above the other in a height direction perpendicular to a centerline of the through channel, wherein the first light source assembly is configured to emit a first light beam, and the second light source assembly is configured to emit a second light beam; and a light adjustment module mounted in the through channel and configured to adjust light emitted by the first light source assembly and the second light source assembly, wherein the light adjustment module comprises: a first collimating lens disposed in a path of the first light beam and configured to collimate the first light beam; a second collimating lens disposed in a path of the second light beam and configured to collimate the second light beam; a first mirror mounted in a path of the first light beam collimated by the first collimating lens and reflecting the first light beam; an optical filter mounted in a path of the first light beam reflected by the first mirror and reflecting the first light beam and allowing the second light beam to pass through; a second mirror mounted in a path of the first light beam reflected by the optical filter and in a path of the second light beam and reflecting the first light beam and the second light beam; and a beam splitter mounted in a path of the light beams reflected by the second mirror and reflecting the light beams to a human eye. a housing having a first opening at one end and a second opening at the other end, with a through channel formed inside the housing and extending from the first opening to the second opening; a first light source assembly and a second light source assembly mounted in the through channel and arranged one above the other in a height direction perpendicular to a centerline of the through channel, wherein the first light source assembly is configured to emit a first light beam, and the second light source assembly is configured to emit a second light beam; and a light adjustment module mounted in the through channel and configured to adjust light emitted by the first light source assembly and the second light source assembly, wherein the light adjustment module comprises: a first collimating lens disposed in a path of the first light beam and configured to collimate the first light beam; a second collimating lens disposed in a path of the second light beam and configured to collimate the second light beam; a first mirror mounted in a path of the first light beam collimated by the first collimating lens and reflecting the first light beam; an optical filter mounted in a path of the first light beam reflected by the first mirror and reflecting the first light beam and allowing the second light beam to pass through; a second mirror mounted in a path of the first light beam reflected by the optical filter and in a path of the second light beam and reflecting the first light beam and the second light beam; and a beam splitter mounted in a path of the light beams reflected by the second mirror and reflecting the light beams to a human eye.
