| Title: |
Color Combining Illumination Device |
| Abstract: |
An illumination device comprising a first light source generating first
light beam having a first spectral distribution and a second light source
generating a second light beam having a second spectral distribution. A
first dichroic reflector is positioned in the first light beam and
transmits a part of the first light beam and reflects a part of the
second light beam. The first and second light beam propagates initially
primarily in a first direction along an optical axis and reflecting means
reflects the second light beam towards the dichroic reflector. The light
sources, the dichroic reflector and reflecting means are mutually
arranged such that the second light beam propagates primarily in a second
direction substantially opposite the first direction and towards the
first light source after being reflected by the reflecting means and such
that the second light beam propagates substantial in the first direction
after being reflected by the dichroic reflector.
