Title:
光源
Document Type and Number:
Japanese Patent JP2006524909
Kind Code:
A
Abstract:
A light source, such as for a projection system, having a plurality of semiconductor chips and at least two different, electromagnetic-radiation-emitting chip types with different emission spectra, each semiconductor chip having a chip coupling-out area through which radiation is coupled out. Furthermore, the light source has a plurality of primary optical elements, each semiconductor chip being assigned a primary optical element, which in each case has a light input and a light output and reduces the divergence of at least part of the radiation emitted by the semiconductor chip during the operation thereof. The semiconductor chips with the primary optical elements are arranged in at least two groups that are spatially separate from one another, with the result that the groups emit separate light cones during operation of the semiconductor chips. The separate light cones of the groups are superposed by means of a secondary optical arrangement to form a common light cone.
