In this way, as long as there is sunlight, the solar cell 2 can be used to provide power to the inner red dot module to ensure the normal operation of the inner red dot module, and it can adapt to changes in ambient brightness. For example, when the ambient brightness increases, The brightness of the output light of the inner red dot module also becomes brighter, and vice versa, it decreases with the dimming of the ambient brightness, which is very convenient without manual operation. More importantly, the inner red dot sight always relies on the battery to power the inner red dot module in this use. It can be supplemented by solar cells in sunny environments. In weak or no ambient light Under normal circumstances, it can still be used normally with the help of battery power.

Combined with Figure 8, it is not difficult to see that solar cells are used to provide power for the micro-current LED light source, that is, the circuit powered by solar cells and batteries drives the inner red dot module at the same time, and the battery provides an extremely small The basic current makes the inner red dot emit a faint light, which is visible in the dark environment at night. When the ambient light becomes stronger, the basic current provided by the battery remains unchanged. After the solar cell receives the ambient light, it supplies a part of the current to the inner red dot module to increase the brightness of the inner red dot. And as the ambient light changes, the current provided by the solar cell also changes, so the brightness of the inner red dot module will change with the change of ambient light.
