Light pipe optical coupling between led and fiber optics cable
First Claim
1. In combination,a) a mounting means having a longitudinal axis,b) an LED having a light emitter and a light-passing lens oriented along said axis,c) a cable having optical fibers defining a light entrance end in a location facing longitudinally toward the LED and spaced therefrom, andd) a light-reflecting light pipe located longitudinally between the LED lens and said cable entrance end,e) and including a hollow connector connected to said mounting means and having a first portion to receive said cable and to position said cable entrance end at said location, the connector having grip means thereon to grip the cable and to resist endwise withdrawal of the cable relative to said connector and mounting means.

27. The method of forming a combination that includes:
-
a) a mounting means having a longitudinal axis, b) an LED having a light emitter and a light-passing lens oriented along said axis, c) a cable having optical fibers defining a light entrance end in a location facing longitudinally toward the LED and spaced therefrom, and d) a light-reflecting light pipe located longitudinally between the LED lens and said cable entrance end, said method including attaching said mounting means containing said LED and light pipe to a support structure, and then endwise inserting said cable into said mounting means to bring said entrance end into said location, and including providing a cable connector, attaching the connector to said mounting means, and providing grip means on the connector to grip the cable and hold the cable at said location. - View Dependent Claims (28)
