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.
2 . The dual-light-source red dot sight according to claim 1 , wherein the beam splitter is obliquely disposed facing the second light source assembly, and an exit direction of the light beams reflected by the beam splitter is opposite to a light beam emitting direction of the first light source assembly and the second light source assembly.
3 . The dual-light-source red dot sight according to claim 1 , wherein the beam splitter is obliquely disposed facing away from the second light source assembly, and an exit direction of the light beams reflected by the beam splitter is the same as a light beam emitting direction of the first light source assembly and the second light source assembly.
4 . The dual-light-source red dot sight according to claim 1 , wherein the first light source assembly further comprises a first adjustment mechanism, and the second light source assembly further comprises a second adjustment mechanism, the first adjustment mechanism and the second adjustment mechanism being respectively configured to independently adjust emission characteristics of the first light source assembly and the second light source assembly.
5 . The dual-light-source red dot sight according to claim 4 , wherein the first adjustment mechanism and the second adjustment mechanism are physical keys, touch switches or adjustment rotating screws.
6 . The dual-light-source red dot sight according to claim 1 , wherein the first light source assembly further comprises a first windage adjustment port and a first elevation adjustment port, which are respectively configured to adjust a windage angle and an elevation angle of the first light beam; and the second light source assembly further comprises a second windage adjustment port and a second elevation adjustment port, which are respectively configured to adjust a windage angle and an elevation angle of the second light beam.
7 . The dual-light-source red dot sight according to claim 1 , further comprising a first power supply module and a second power supply module disposed within the housing, wherein the first power supply module is configured to supply power to the first light source assembly, and the second power supply module is configured to supply power to the second light source assembly.
8 . The dual-light-source red dot sight according to claim 1 , wherein the first light source assembly and the second light source assembly are arranged to be staggered from each other in a direction perpendicular to the centerline of the through channel.
9 . The dual-light-source red dot sight according to claim 1 , wherein the first light source assembly and the second light source assembly are arranged to be aligned with each other in a direction perpendicular to the centerline of the through channel.
