When the ambient brightness is low or the battery module is aged and has insufficient power, the main control module controls the AC power module 20 to directly supply power to the light source module 30 for emergency lighting. When the light is insufficient, the main control module controls the AC power module 20 to recharge the battery module.
[0020] like Figure 1 As shown, the solar charging module 10 includes a solar panel and an MPPT fast charging module. The input end of the MPPT fast charging module is electrically connected to the solar panel, and the output end of the MPPT fast charging module is electrically connected to the charging end of the battery module.
