FLUORESCENT WHEEL FOR PROJECTOR AND LIGHT-EMITTING DEVICE FOR PROJECTOR

摘要

PROBLEM TO BE SOLVED: To provide a fluorescent wheel for a projector that can suppress a phosphor layer from being heated, and a light-emitting device for a projector using the same.SOLUTION: A fluorescent wheel for a projector includes: 1 phosphor layer 12; a ring-shaped ceramic board 11 that has a first principal surface having the phosphor layer 12 provided thereon and a second principal surface located on the opposite side of the first principal surface, and has a thermal conductivity higher than that of the phosphor layer 12; and a reflection layer 13 that is provided on the second principal surface of the ceramic board 11.
