The LlNEX (TM) barrier discharge is a Mercury free fluorescent lamp based on the principles of barrier discharges using Xe excimers as UV emitting species. In contrast to standard fluorescent lighting the lamp can be equipped with an optional internal reflector to concentrate the light output onto a small aperture thus gaining high luminance. The inner surface of the glass carries a sandwich layer of strip electrodes, barrier, reflector and phosphor coating. Partof the reflector is removed to create an aperture through which the light can escape. UV is created in an effective manner by excitation of Xenon excimers and converted into the visible light of the desired color. The optical performance of the LlNEX (TM) lamp has been optimized by means of numerical simulations. Photometry measurements were in agreement with the model. Two different versions of the aperture setup have been compared in order to find the optimum geometry for several automotive applications. A coated aperture version may be applicable for a backlight solution due to the high overall coupling efficiency. The clear configuration performs better in projection optics such as slim linear luminaire designs due to the advantage in luminance. Since the light source hag a very homogeneous appearance it can be used for instance in turn indicator applications, which hag been so far a domain of Neon signal lighting.
