Radiation source and method for producing a lens mould
First Claim
1. A radiation source with many radiation-emitting semiconductor chips disposed side by side, whereina field of integrally formed lenses, forming a hexagonal lattice, is disposed upstream, in the projection direction, of the semiconductor chips, andwherein color groups of the semiconductor chips are disposed in respective lines such that all the semiconductor chips in any given line are of an identical color group, with the color groups having their respective maximum emissions at different wavelengths.

Abstract
A radiation source has a field of semiconductor chips, which are disposed below a field of micro-lenses (8) disposed in a hexagonal lattice structure. The radiation source is distinguished by high radiation output and radiation density.
