Abstract

A method and apparatus is described for producing high brightness, e.g. multicolor light, whereby a region of a wavelength conversion element and a light source producing excitation light are moved relative to each other so that said region is exposed to the excitation light at different times and in a progressive movement that scans across a part of the entire surface of the wavelength conversion element. The wavelength conversion element can be cooled by air or with a liquid.
