LASER DIODE MOUNTING SUBSTRATE FOR AUTOMOTIVE LAMP MODULE

摘要

Provided is a laser diode mounting substrate for an automotive lamp module using a laser diode. The substrate includes: a substrate body with a power supply circuit pattern, which electrically connects a connector with a contact point of the laser diode, on the top; a first heat conduction layer disposed at the area except for the power supply circuit pattern, on the top of the substrate body; and a second heat conduction layer disposed on the bottom of the substrate body, in which at least one heat transfer hole is disposed through the first heat conduction layer, the substrate body, and the second heat conduction layer. Therefore, the present invention provides an effect that heat generated by the laser diode can be effectively dissipated.
