Radiation source for producing electromagnetic radiation having a first wavelength region comprises electrodes connected to an alternating voltage source, a gas-filled transparent discharge vessel and a dielectric layer

摘要

Radiation source (1) comprises electrodes (3) connected to an alternating voltage source (7), a gas-filled transparent discharge vessel (2) for electromagnetic radiation of a second wavelength region which partially overlaps a first wavelength region and a dielectric layer for radiation of the second wavelength region. The radiation source also has a luminous layer containing luminous particles.
