Title:
DRIVING CIRCUIT AND METHOD COMPATIBLE WITH SILICON CONTROLLED RECTIFIER AND WIRELESS DIMMING, AND LAMP AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/245784
Kind Code:
A1
Abstract:
Disclosed in the present invention are a driving circuit and method compatible with a silicon controlled rectifier and wireless dimming, and a lamp and a system. The driving circuit comprises: an angle measurement module, which is connected to a silicon controlled rectifier dimmer, and is used for acquiring conduction angle data of the silicon controlled rectifier dimmer; a wireless control module, which is connected to the angle measurement module, and is used for generating a control signal according to the conduction angle data of the silicon controlled rectifier dimmer and in response to a gesture operation adjustment instruction; and a power supply adjustment module, which is connected to the silicon controlled rectifier dimmer and the wireless control module, and is used for acquiring a power supply signal transmitted by the silicon controlled rectifier dimmer and generating a driving signal according to the control signal. The technical solution provided in the embodiments of the present invention can be compatible with the dimming requirement of a target user, make silicon controlled rectifier and wireless dimming functions be compatible, improve a dimming effect, and thus meet the deep dimming requirement of the target user.
