Abstract:
1. A system for collimating light emitted from a plurality of light emitting diodes (LED) dies, the system comprising: a channel comprising a light engine, the light engine comprising a plurality of light emitting diodes (LED) dies positioned within the channel, at least one of the plurality of LED dies emits light at a color temperature different than another one or more of the plurality of LED dies within the channel; a light transfer medium having a bottom side configured to be positioned a predetermined distance above a surface of the plurality of LED dies and having a top side configured to establish a predetermined emitting angle of light from the plurality of LED dies that traverse the light transfer medium; and wherein the light transfer medium is configured to collimate light from the plurality of LED dies along a length of the light transfer medium covering the channel within the predetermined emitting angle and to average color temperatures of light from the plurality of LED dies.
