An optical transmission system couples light from a surface mount LED module, secured to a printed circuit board, to a lens unit on a remotely located panel via a light pipe. The surface mount LED module includes a cylindrical housing with a flat bottom surface, adaptable to be mounted on the board's surface, and a blind bore for receiving one end of the light pipe. An LED chip set, comprised of one or more individual LEDs, is positioned in the housing at the base of the blind bore with leads having one end thereof connected to respective LED electrodes, the other ends extending outside of the housing for connection to conductive pads on the board.
