The utility model provides a car light light type converting means uses up type transform drive arrangement, light type transform drive arrangement includes the casing, the rotor, and the stator, pivot and end cover, inside stator and the stator winding of casing constitutes a pair of exciting circular -arc stator poles of electricity that adds, the rotor is fixed in the pivot for circle arc -shaped permanent magnet, arrange the magnetic field of the circular -arc magnetic pole of stator in, rotor and the cooperation of circular -arc stator poles are formed with the closed magnetic circuit of air gap, the both ends of pivot connect respectively one along the radial pendulum rod that extends of pivot, car light light type converting means's light screen, fixed connection is in on the pendulum rod at pivot both ends, the angle of oscillation of light screen with the corner of rotor is the same, adopts the mode of rotation type electromagnetism actuating mechanism drive light screen to realize the transform of light type, and the collision noise that can send when reducing the electro -magnet actuation with release provides more comfortable driving environment for the user.
