Abstract
A phosphor module for a laser light source includes a radiating body, a phosphor layer disposed at the radiating body, the phosphor layer being configured to absorb light having a first wavelength and emit light having a second wavelength different from the first wavelength, a reflective layer that surrounds a side surface of the phosphor layer and is configured to reflect light, and a black matrix layer disposed at the reflective layer and configured to absorb light. The black matrix layer is disposed at an edge of the phosphor layer.
