Abstract

The invention relates to a control circuit and an LED lamp circuit. The control circuit comprises: a solar power supply circuit for converting solar energy into electric energy for power supply; an adapter circuit for rectifying, transforming and converting input power and then supplying power; a power supply management circuit for switching large current to charge a battery and switching the adapter circuit to supply power to a control circuit and a voltage transformation circuit when the adapter circuit is opened, and switching small current to charge the battery and switching the battery tosupply power to the control circuit and the voltage transformation circuit when the adapter circuit is not opened; a battery for supplying power to the control circuit and the voltage transformationcircuit; the control circuit for controlling the switching of the voltage transformation circuit; and the voltage transformation circuit for transforming the input voltage. According to the invention,intelligent switching between a power supply mode and a charging mode is achieved through the power supply management circuit, so that scalding of the battery is avoided, and the service life of theproduct is prolonged.

Description

technical field [0001] The invention relates to the technical field of power supply control circuits, in particular to a control circuit and an LED lamp circuit. Background technique [0002] Solar energy is a renewable energy source. Refers to the sun's thermal radiation energy, the main performance is often said that the sun's rays. Due to the advantages of being clean and renewable, solar panels are also widely used in the power supply of various electrical equipment, which can greatly reduce the power consumption of the equipment. [0003] In the existing technology, electrical equipment generally only uses adapters for power supply, or only uses solar panels for power supply, and uses energy storage equipment such as lithium batteries for energy storage at the same time; some electrical equipment uses solar energy and adapter power supply methods. . However, devices using two power supply modes often need to switch the power supply mode manually, and cannot perform a...
