Abstract
Provided is a light transmitter, including: a substrate; a semiconductor refrigeration assembly arranged on the substrate; a light emitting assembly mounted on the semiconductor refrigeration assembly, so that the semiconductor refrigeration assembly cools the light emitting assembly, and the light emitting assembly is configured to generate a laser beam; a tube shell mounted on the substrate to package the semiconductor refrigeration assembly and the light emitting assembly; an optical fiber configured to output the laser beam generated by the light emitting assembly to an outside of the tube shell; and a transparent filling glue filled in a space between an inner wall of the tube shell and the substrate, and configured to guide the laser beam generated by the light emitting assembly to the optical fiber and transfer a heat generated by the light emitting assembly to the tube shell.
