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.
