The electrodeless dimming lamp has the advantages of simple circuit, simple manufacturing, smooth dimming and no flicker during low light.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an electrodeless dimming lamp. Background technique [0002] In the prior art, the stepless dimming lamp can realize the brightness adjustment of the lamp from 0-100%, but it is easy to appear flickering phenomenon in low light. In order to achieve smooth output and achieve better dimming effect, adjustable potentiometers and peripheral circuits are often used. CN 200810203395.X discloses a dimming circuit for electrodeless fluorescent lamps; As for the lamp driving circuit, the structures of the above two patented technologies are complicated and the production cost is high. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a stepless dimming lamp with simple circuit, easy manufacture, smooth dimming, and no flickering in weak light, which can be used as a desk lamp for writing or a bedside lighting lamp.
