Abstract:
A phosphor module for a laser light source includes a heat dissipation body, and a reflective layer disposed on the heat dissipation body including metal or an alloy. The phosphor module also includes a phosphor layer disposed on the reflective layer. The phosphor layer includes a glass frit and a phosphor and is configured to: absorb a first light emitted from the laser light source and incident on a first surface of the phosphor layer facing away from the reflective layer; and emit, from a second surface of the phosphor layer opposite the first surface and facing towards the reflective layer, a second light having a second wavelength different from a first wavelength of the first light. The phosphor module also includes a light-transmissive transparent heat dissipation layer disposed on the first surface of the phosphor layer that dissipates heat from the phosphor layer.
