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.

Abstract: A micro-lens array includes a shutter bezel substrate, a first lens substrate having a first inner surface in contact with a first surface of the shutter bezel substrate, a first lens array disposed at a first outer surface of the first lens substrate that is opposite to the first inner surface of the first lens substrate, a second lens substrate having a second inner surface in contact with a second surface of the shutter bezel substrate, and a second lens array disposed at a second outer surface of the second lens substrate that is opposite to the second inner surface of the second lens substrate. At least one of the first lens substrate or the second lens substrate includes an alignment mark that is configured to guide placement of the first lens array on the first lens substrate and the second lens array on the second lens substrate.

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.

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.
