Low-standby-power-consumption lighting circuit and lighting lamp

The invention discloses a low-standby-power-consumption lighting circuit and a lighting lamp. The low-standby-power-consumption lighting circuit comprises an AC/DC conversion circuit, a lighting driving circuit, a voltage conversion circuit and a switching circuit. The AC/DC conversion circuit performs different DC voltage conversion on the mains supply to obtain a first voltage signal and a second voltage signal. The lighting driving circuit drives the illuminating lamp to illuminate under the power supply of the first voltage signal and in an illumination driving state. The voltage conversion circuit performs voltage conversion on the second voltage signal and then supplies power to the wireless module. When the lighting lamp is in a standby state, the wireless module controls the switchcircuit to cut off the power supply circuit of the lighting drive circuit, so that the lighting drive circuit stops working. Visibly, the illumination driving circuit does not work when the illumination lamp is in the standb
