Abstract: The phosphor disc disclosed here includes the following structural elements: a disc-shaped metal plate; a phosphor layer disposed circumferentially on the metal plate; and a bonding layer for bonding the phosphor layer to the metal plate. The metal plate curves convexly toward the phosphor layer.

Abstract: A phosphor wheel includes a disc-shaped substrate and a phosphor ring fixedly bonded to the substrate. At least three cut-out sections or openings are formed on a rim of the substrate. The shortest length from the center of the substrate to inner edges of the cut-out sections or inner edges of the openings is generally equal to a radius of an outer circumference of the phosphor ring.

Abstract: A phosphor wheel includes: a substrate; a light reflection layer disposed on one surface of the substrate; a phosphor layer; and a bonding layer which is located between and bonds the light reflection layer and the phosphor layer, wherein the bonding layer contains a particle which is higher in thermal conductivity than a base material of the bonding layer and higher in light reflectance than the light reflection layer.

Abstract: A phosphor wheel module includes a substrate and a phosphor region disposed on a surface of the substrate. The phosphor region includes a phosphor that is disposed on at least a part of a circumference of a circle with a first radius from a rotation center of the substrate. The substrate includes a ventilation region and a heat conduction region. The ventilation region includes a plurality of openings that is located closer to the rotation center of the substrate than the phosphor region. The heat conduction region is located farther away from the rotation center of the substrate than the phosphor region.
