Claim Text:
1. An automotive lamp module comprising: a substrate comprising a substrate body having an upper surface and a lower surface facing away from the upper surface; a laser diode installed onto the substrate over the upper surface; a lower heat sink coupled to the substrate over the lower surface; an upper heat sink coupled to the substrate over the upper surface; a light channel guide disposed through the upper heat sink and aligned with the laser diode to provide a light channel from the laser diode; a phosphor disposed in alignment with the light channel, a power connector integrated with the substrate body; an upper heat conduction layer formed over the upper surface of the substrate body; a lower heat conduction layer formed over the lower surface of the substrate body; and a power supply circuit pattern formed over the lower surface of the substrate body and electrically connected to the power connector, wherein the lower heat conduction layer is formed over an area except where the power supply circuit pattern is formed, wherein at least one through hole is formed through the upper heat conduction layer, the substrate body, and the lower heat conduction layer.
