A rotary device for setting function includes a ring for setting function (0103), a rotary base (0104). The ring for setting function (0103) is installed on the rotary base (0104). A pointing mark for function is indicated on the outer surface of the ring for setting function (0103). An identifier for the photoelectric function of a product is indicated on the outer surface of the rotary base (0104). A control structure inside the ring for setting function (0103) controls a control component by an adaptive transmission mechanism. The ring for setting function (0103) shows the action of the control component by the pointing mark for function pointing at the identifier on the rotary base (0104). The device cooperating with a control circuit of the product enables the setting of the brightness or twinkle mode of multifunctional LED torches or LED lights by diverting a switch or adjusting the parameters of the control component. |
