Title:
POWER SUPPLY CIRCUIT, DALI MODULE, LIGHTING EQUIPMENT AND CONTROLLING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/261818
Kind Code:
A1
Abstract:
A power supply circuit, a DALI (digital addressable lighting interface) module, a lighting equipment and a controlling method. The power supply circuit includes: a power source circuit (100); a regulating transistor (Q161), configured to be connected between the power source circuit and a first output port (DA+); a first controller (U160), configured to control the regulation transistor (Q161) to be turned on or off; and a current regulation controller (A), configured to be connected between the power source circuit and a second output port (DA-), the current regulation controller (A) being further connected between the regulating transistor (Q161) and the first controller (U160), when a current of the second output port (DA-) being larger than a preset value, the current regulation controller (A) turning down a current flowing through the regulating transistor (Q161).
