Abstract
Official abstract text for this publication.
The present invention relates to a light collector for an illumination device collecting light from a plurality of light sources and combing the collected light into a common light beam, where the common light beam is coupled through an optical gate. The light sources are distributed offset and around an optical axis and the light beam collector comprises a first reflector surrounding the optical axis and a second reflector surrounding the optical axis, where the first reflector reflects the sources light beams towards the second reflector and where the second reflector reflects the source light beams in a direction along the optical axis. The light beam collectors is divided into a number of reflector pairs, where each reflector pair comprises a first surface part of the first reflector and a second surface part of the second reflector, where the second surface part receives light from the corresponding first surface part of the reflector pair.
First claim
Opening claim text (preview).
The invention claimed is: 1. An illumination device, comprising: a plurality of light sources distributed offset and around an optical axis, wherein said plurality of light sources generates a plurality of source light beams; and a light beam collector adapted to combine said source light beams into a common light beam propagating along said optical axis, said light beam collector comprising: a first reflector surrounding said optical axis, and a second reflector surrounding…
