Abstract: A phosphor module for a laser light source includes a heat radiator, a phosphor layer disposed at the heat radiator and configured to absorb and emit light, where a wavelength of the emitted light is different from a wavelength of the absorbed light, a reflective layer that covers a side surface of the phosphor layer and is configured to reflect light, and an adhesive layer disposed between the phosphor layer and the heat radiator and between the reflective layer and the heat radiator, the adhesive layer being configured to couple each of the phosphor layer and the reflective layer to the heat radiator. A thermal conductivity of the adhesive layer is greater than a thermal conductivity of each of the phosphor layer and the reflective layer.

Abstract: A phosphor module for a laser light source includes a heat radiator, a phosphor layer disposed at the heat radiator to absorb and emit light, in which a wavelength of the emitted light is different from a wavelength of the absorbed light, and a reflective layer disposed on a surface of the phosphor layer and configured to reflect light. The phosphor layer includes a protrusion portion that protrudes from the surface of the phosphor layer and that extends through the reflective layer.
