  • Phosphor wheel having a balancing piece
    Patent number: 11402625
    Abstract: A phosphor wheel (300, 400, 500, 600) includes an annular disc (310, 410, 510, 610) having phosphor segments (320, 420, 522, 524, 620) and an exposed annular sector (305, 405, 505, 605), a hub (330, 430, 530, 630) coupled to the inner perimeter (304, 413) of the annular disc, and a balancing piece (340, 440, 540, 640) located between the hub and the exposed annular sector. The balancing piece minimizes the initial imbalance of the phosphor wheel about the center (301, 441, 541) of the disc due to the exposed annular sector by making up the difference in torque. A method for making a phosphor wheel, a projector comprising a phosphor wheel, and a method for minimizing imbalance in a phosphor wheel.
