Title:
CANDLE LAMP AND CIRCUIT FOR IMPLEMENTING PERSISTENCE OF VISION EFFECT THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/051263
Kind Code:
A1
Abstract:
The present application relates to the technical field of candle lamps and provides a candle lamp and a circuit for implementing a persistence of vision effect thereof. According to embodiments of the present application, an optical signal in an environment is collected by a daylighting panel and is converted into a weak current signal, so that power supply can be implemented by using the optical signal in the environment, which is low-carbon and environmentally-friendly, and it is not required to provide an additional battery; the weak current signal is collected by means of an I/O port of a controller to charge an energy storage module, so that the weak current signal can be effectively collected, and the weak current signal is directly collected by means of the I/O port, which is low in power consumption and can effectively reduce power loss; a pulse signal is output to at least one LED lamp by means of the controller, so as to adjust the magnitude and frequency of a drive current signal output by the energy storage module to the at least one LED lamp, thereby driving the at least one LED lamp to flicker and implementing the persistence of vision effect of the candle lamp. The present invention may implement a more realistic flame jumping effect, does not need to provide a swing device, and is simple in structure and low in power consumption.
