When the first driving device 11 is operated, the first arm 13 is interfered by an external force to rotate or the first driving device 11 is easily out of step in the start-stop stage, at this time, the internal rotation parameter of the first driving device 11 does not correspond to the actual rotation position, and when the first triggering portion 1141 triggers the first position detecting unit 115, the first position detecting unit 115 sends an electric signal to the first driving device 11 to correct the internal rotation parameter of the first driving device 11, so that the internal rotation parameter of the first driving device 11 corresponds to the actual rotation position again.

For example, assuming that the first position detection unit 115 is located at a position of 60 degrees in the forward rotation, when the first driving device 11 rotates forward by 20 degrees, the external force interferes the rotation of the first arm 13 to make the first driving device 11 rotate reversely by 10 degrees, at this time, the first driving device 11 is actually in the rotation position of normal rotation by 10 degrees, the internal rotation parameter of the first driving device 11 is still in the normal transmission by 20 degrees, i.e. the internal rotation parameter of the first driving device 11 does not correspond to the actual rotational position, at this time, the first driving device 11 continues to rotate in the forward direction by 50 degrees, at this time, the first driving device 11 is actually at the rotational position of rotating in the forward direction by 60 degrees, the internal rotation parameter of the first driving device 11 is at the positive rotation of 70 degrees, the first triggering portion 1141 triggers the first position detecting unit 115, and the first position detecting unit 115 sends an electrical signal to the first driving device 11 to correct the internal rotation parameter of the first driving device 11 to the positive rotation of 60 degrees.

Specifically, referring to fig. 4, since the first driven gear 114 and the first arm 13 rotate synchronously, the first triggering portion 1141 is disposed on the first driven gear 114, and similarly, since the second driven gear and the second arm 14 rotate synchronously, the second triggering portion is disposed on the second driven gear.

Further, please continue to refer to fig. 3 and fig. 4, there are a plurality of first position detecting units 115, and correspondingly, there are a plurality of first triggering portions 1141; and/or a plurality of second position detection units are provided, and correspondingly, a plurality of second triggering parts are provided. The greater the number of the first position detection units 115 and the second position detection units provided, the higher the control accuracy of the first driving device 11 and the second driving device 12. Specifically, in order to balance between the production cost and the control accuracy, the number of the first position detection units 115 is three, and the first position detection units are respectively located at the rotation start point, the rotation middle point, and the rotation end point.

In an embodiment, please refer to fig. 1, the shadowless lighting device further includes a rotating base 40 for mounting the controller 30, and the rotating base 40 is rotatably mounted on the first arm 13 or the second arm 14.
