Abstract
An optoelectronic module for emitting monochromatic radiation in the visible wavelength range is specified. The module has a plurality of light emitting diode chips which generate UV radiation. The UV radiation is converted into light in the visible range, for example, into green light, by a wavelength converter. The coupling-out of light from the module is optimized by the use of two selectively reflecting and transmitting filters. This module can be used as a light source in a projection apparatus.
