| 摘要 |
The present invention relates to an illumination system comprising at least one light source and an optical light mixing rod (908). The illumination system comprises a rod holder holding the optical light mixing rod in a position, where the entrance surface (911) of the optical light mixing rod (908) is arranged above the emitting window (105) of the light source. The optical light mixing rod is from in a flexible and solid transparent material and 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 (911) of the optical light mixing rod (908) and the emitting window (105) of the light source together. The optical light mixing rod (908) comprises a bulge of the entrance surface and the pressure force presses the bulge flat against the emitting window of the light source. |
