Abstract

The metal-halide lamp is a High Intensity Discharge (HID) lamp with a high efficiency. The salt additive (DyI3) acts as prime radiator. The present lamp suffers from non-uniform light output, caused by diffusion and convection processes. To gain a better understanding of the lamp, the convection is varied by vaying the gravity. The latest addition is a centrifuge (diameter 3 metres), whisch can go up to 10g. Lateral Dy profiles and radial temperature profiles are obtained by means of emission spectoscopy. In addition, laser absorption spectroscopy is used to obtain a 2D Dy density image. The first results will be presented.
