ROTATING FIXING DEVICE AND LIGHTING DEVICE COMPRISING THE DEVICE

摘要

The present invention relates to a rotating fixing device for a lighting device, wherein, the lighting device comprises a fixedly arranged assembling ring (1) and a rotating ring (2) that rotates with respect to the assembling ring (1), wherein, the rotating fixing device comprises a first disc (3) in anti-torsion connection with the rotating ring (2) and a second disc (4) in anti-torsion connection with the assembling ring (1), wherein the first disc (3) and the second disc (4) respectively comprise a first teeth portion (5) and a second teeth portion (6), and the first teeth portion (5) engages with the second teeth portion (6) to realize locking the rotating angle of the rotating ring, and the first teeth portion (5) disengages from the second teeth portion (6) to realize adjusting the rotating angle of the rotating ring. The rotating fixing device according to the present invention can reliably maintain the lighting device at a predetermined irradiating angle, and the life span of the overall lighting device will not be shortened with the increase in the number of times of adjusting the angle. In addition, the present invention also relates to a lighting device comprising the above rotating fixing device.
