The invention provides a solar street lamp controller with a mains supply charging function. The solar street lamp controller includes an MCU, an MCU voltage-stabilized power source, a storage battery, a solar panel charging module, a solar panel voltage detection module, a storage battery voltage detection module, a load driving module, a working state indication module, an environment temperature detection module, a crystal oscillator module, a manual switch and a mains supply charging module; when detecting a time duration in which the power of the storage battery is lower than a first predetermined value exceeds a predetermined time period, the MCU is automatically switched to a mode in which the mains supply charging module supplies power for the storage battery and a load; and when detecting the capacity signal of the storage battery achieves a second predetermined value, the MCU is automatically switched to a mode in which solar energy is utilized to supply power for the storage battery and the load. According to the solar street lamp controller with the mains supply charging function, the mains supply charging module is utilized to perform backup power supplement for the insufficiency of solar power generation, and therefore, incapability of switching on the load normally, which is caused by the insufficiency of power generation of solar panels in long-term rainy days can be prevented.
Description
technical field [0001] The invention relates to the technical field of control circuits for solar street lamps, in particular to a solar street lamp controller with a commercial power charging function. Background technique [0002] At present, when the solar street light controller is in a long-term rainy day or in an environment with poor lighting conditions, the battery power is very low due to insufficient solar power generation. affect the lives of users. [0003] In order to solve the above-mentioned technical problems, it is necessary to provide a solar street lamp controller with a mains charging function. Contents of the invention [0004] The main technical problem to be solved by the present invention is to provide a solar street lamp controller with a mains charging function. By setting the mains charging module as a backup supplement for the solar charging method, it is possible to prevent the street lights from being unable to turn on normally due to insuffi...
