Abstract

See full text

An LED package includes a LED structure that outputs light in a pattern about an axis and an optical coupling device with a central axis. The coupling device is positioned relative to the LED structure and accepts light from the LED. The coupling device includes a first dielectric interface surface that is substantially cylindrical with respect to the central axis, and a reflecting surface. The first dielectric interface surface accepts a first portion of light from the LED structure and directs it toward the reflecting surface. The reflecting surface accepts the light from the first dielectric interface surface and directs it toward the first dielectric interface surface in a direction substantially perpendicular to the central axis.
