Abstract
The disclosure provides a dimmable torch, in order to overcome the insufficiency of the dimming control function of the torch in the prior art. The torch comprises a lamp holder (1), a tube body (3) and a tail cap (5), wherein a battery (10) is arranged in the tube body (3); a control circuit (9) is arranged in the tail cap (5) of the torch; the second end (V−) of the control circuit is connected with the cathode of the battery (10); a microcomputer control system (8) on the control circuit (9) can control the on/off of a loop of the cathode of the second end of the driving circuit (11) and the cathode of the battery (10) to implement dimming. Due to the disclosure, the grouped multi-gear dimming mode of the torch can be controlled conveniently.
