| Title: |
Illumination Device with Multi-Layered Heat Sink |
| Abstract: |
The present invention relates to an illumination device where a number of
light sources are arranged on a heat sink and adapted to emit light in
substantially the same direction. The heat sink comprises a first cooling
plate and a second cooling plate. A first part of the light sources are
arranged on the first cooling plate and a second part of the light
sources are arranged on the second cooling plate. The first and second
cooling plates are separated by a distance and a flow channel is defined
there between. The flow channel allows cooling fluid to flow between the
first cooling plate and the second cooling plate whereby the light
sources can be cooled by the cooling fluid. The heat sink comprises
further a number of light passages allowing light to propagate from the
second cooling plate, towards the first cooling plate and through the
first cooling plate.
