Abstract
A light source (100) includes a plurality of light emitting devices (101), each of which output light that is collimated by a first focusing structure (103). The collimated light is input to second focusing structure (104), which focuses light from the light emitting devices as a single beam that is substantially homogeneous. The light source may be used in an LCD display, a projection system, a television system, or a computer monitor, to name a few applications.
