摘要：
A dual fluorescent wheel with two disk-shaped carrier elements which are interconnected by wing-type cooling ribs is disclosed. When the dual fluorescent wheel rotates, air flows in through an axial opening in one of the carrier elements, the air flows radially through the interspace between the carrier elements or the wing-type cooling ribs and flows out at the edge. This airflow improves the dissipation of heat which is produced when an excitation laser irradiates the annular fluorescent strips located on the two exterior faces.
