The utility model relates to the technical field of red dot sighting
telescope, and discloses a brightness compensation structure used on a red dot sighting
telescope, which comprises a red dot sighting
telescope main body shell, a mounting groove is arranged on the upper surface of the red dot sighting telescope main body shell, and a storage battery mounting box is fixedly connected to one side of the inner wall of the mounting groove. According to the utility model, the brightness of the illumination
light source can be automatically adjusted according to the environment illumination condition through the arrangement of the device, it is ensured that an
aiming point is always clear and visible, the use performance in different illumination environments is improved, and through the integrated solar panel, the illumination intensity of the illumination
light source is improved. According to the device, the storage battery can be charged under the illumination condition, self-sufficiency of energy is achieved, dependence of an external power source is reduced, using convenience and reliability are improved, a red dot sighting telescope body shell is well protected, the influence of external environment factors on internal electronic components is reduced, and durability and stability of the device are improved.
