Abstract: Traditional methods of making headlamp coils have left a portion of the coils with slightly irregular forms. These irregularities can result in defects in the ultimate beam pattern. Accommodating these defects in robust lamp and headlamp optical systems can reduce the performance that might otherwise be available. The preferred coil is therefore continuously coiled as a straight body, and carefully cut into segments. Subsequently, legs are welded to the coil segment ends. The coil is then left substantially undistorted by the manufacturing process that would otherwise normally leave a portion of the coils distorted. The method particularly enables a functional center leg coil.

Abstract: A coil is formed by winding a conductive wire around a winding frame that is being rotated about a rotational axis of the winding frame. Guide members contact the conductive wire being wound around the winding frame to define the winding position of the conductive wire. The guide members are supported by a link mechanism that is provided coaxially with the rotational axis so as to rotate synchronously with the winding frame. As a third actuator moves a driving link in the direction of the rotational axis, the guide members are moved in directions of a diameter of the winding frame. As a first actuator moves a holding link in the direction of the rotational axis, the guide members are moved in the direction of the rotational axis together with the holding link. As a second actuator extends or contracts an arm, one of the guide members is moved independently of another one of the guide members. The first, second and third actuators do not need to rotate together with the winding frame.
