Title:
DALI CIRCUIT, CONTROLLING METHOD AND EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2019/144373
Kind Code:
A9
Abstract:
A lighting interface supply circuit, preferably a DALI interface supply circuit, a controlling method and an equipment. The lighting interface supply circuit includes: a current generator (71), configured to generate current according to a controlling signal, by connecting to a first voltage port (711); a current output port (72), configured to output the current; a ground port (73), configured to connect to ground voltage; and a first protecting transistor (M710), configured to connect between the first voltage port (711) and the current generator (71), the first transistor (M710) is configured to disconnect the current generator (71) and the first voltage port (711), when the current output port (72) and the ground port (73) is reversely connected. Therefore, lower cost and more reliable protection are achieved. In addition, when reverse connection occurs, the behavior of the circuit is the same as the standard DALI interface supply circuit, so that DALI 2.0 can be supported.
