[0031] There are two main power supply modes for existing inner tube red dot sights: one is pure battery power supply mode, and the other is solar power plus battery power supply mode. In the pure battery power supply mode, when the battery is out of power, the inner tube red dot sight cannot work properly, and the battery needs to be replaced frequently, which is quite troublesome. In the traditional solar power plus battery power supply mode, the red dot will flicker when switching from solar power supply mode to battery power supply mode, and the stability is not high, which affects the user experience.

[0032] To this end, the embodiment of the utility model proposes an inner tube red dot sight, which makes the solar power supply more stable by adopting a solar energy storage conversion panel, and can use solar energy to store electricity to charge rechargeable batteries, thereby eliminating the need to replace batteries.

[0033] The following is combined with Figure 1-3 , the inner tube red dot sight and its power supply circuit of the embodiment of the utility model are described in detail.

After the control board 600 receives the voltage, it can control a certain amount of current and voltage through the built-in chip and program, and then control the output current and voltage by adding and subtracting gears, and finally supply the red dot light 700, so that the inner tube red dot sight 100 can work normally.
