Dimmer for electroless lamp

A dimmer for an electroless lamp comprises a dimming interface circuit, a singlechip, an AC/DC (alternating current/direct current) conversion circuit, a DC/AC conversion circuit and an output coupling module, wherein the dimming interface circuit serves as the input of the dimmer for the electroless lamp and connected with the output end of a dimming module; the output end of the dimming interface circuit is connected with the signal input end of the singlechip; the control signal output end of the singlechip is connected with the control signal input end of the DC/AC conversion circuit; the power supply signal input end the DC/AC conversion circuit is connected with the signal output end of the AC/DC conversion circuit; the signal output end of the DC/AC conversion circuit is connected with the signal input end of the output coupling module; and the output coupling module is coupled with a coil on an electroless lamp tube. The dimmer can adjust the lamplight brightness of the electroless lamp as required an
