Illumination system comprising an optical light mixing rod

摘要

The present invention relates to an illumination system comprising at least one light source and an optical light mixing rod. The illumination system comprises a rod holder holding the optical light mixing rod in a position, where the entrance surface of the optical light mixing rod is arranged above the emitting window of the light source. The optical light mixing rod is formed in a flexible and solid transparent material and is accommodated in a hollow part of the rod holder. The rod holder is adapted to provide a pressure force to the optical light mixing rod and the pressure force is adapted to press the entrance surface of the optical light mixing rod and the emitting window of the light source together.

主权项

1. An illumination system comprising:
at least one light source being configured to emit light from an emitting window; an optical light mixing rod being formed of a solid transparent material and comprising an entrance surface, side surfaces and an exit surface, wherein light from the at least one light source enters the optical light mixing rod through the entrance surface and is transmitted through the optical light mixing rod via reflections at the side surfaces and exits the optical light mixing rod through the exit surface; and a rod holder comprising a support part and including a hollow part accommodating the optical light mixing rod and the support part is adapted to fix the optical light mixing rod in a position where the entrance surface is arranged above and in contact with the emitting window; wherein the optical light mixing rod is formed in a flexible and solid transparent material and in that the rod holder comprises a pressure mechanism adapted to provide a pressure force to the optical light mixing rod, the pressure force is adapted to press the entrance surface and the emitting window together.
