Title:
LIGHTING CIRCUIT WITH LOW STANDBY POWER CONSUMPTION, AND LIGHTING FIXTURE
Document Type and Number:
WIPO Patent Application WO/2022/007696
Kind Code:
A1
Abstract:
A lighting circuit with a low standby power consumption, and a lighting fixture. The lighting circuit comprises an AC/DC conversion circuit, a lighting drive circuit, a voltage conversion circuit and a switching circuit. The AC/DC conversion circuit respectively performs different direct-current voltage conversions on mains electricity to obtain a first voltage signal and a second voltage signal; when the lighting drive circuit is powered by the first voltage signal and is in a lighting drive state, the lighting drive circuit drives a lighting lamp to perform lighting; the voltage conversion circuit performs a voltage conversion on the second voltage signal and then supplies power to a wireless module; and when a lighting fixture is in a standby state, the wireless module controls the switching circuit to disconnect a power supply line of the lighting drive circuit, such that the lighting drive circuit stops working. It can be seen that the lighting drive circuit of the present application does not work when the lighting fixture is in a standby state, that is, the lighting drive circuit does not generate standby power consumption when the lighting fixture is in a standby state, thereby reducing the standby power consumption of the whole lighting fixture, and realizing energy conservation and environmental protection.
