| Zusammenfassung: | The utility model discloses a LED lamp control circuit with energy stored in a lithium battery. The LED lamp control circuit comprises a LED light source control circuit, a single chip microcomputer chip, a photovoltaic plate detecting circuit, and a solar-energy charging circuit. The single chip microcomputer chip is connected with the LED light source control circuit, the photovoltaic plate detecting circuit, and the solar-energy charging circuit through control. The LED light source control circuit comprises a LED lamp and a control switch chip ME9926. The control switch chip ME9926 is connected with the single chip microcomputer chip and is used for transmitting the control signal of the single chip microcomputer chip in order to control the power and the conduction of the LED lamp. The photovoltaic plate detecting circuit comprises a photovoltaic plate and a parallel branch connected in parallel with the photovoltaic plate. The parallel branch is used for determining the voltage on the two ends of the ph |
