The Wavien dual paraboloid reflector system is an imaging reflector system having a 1:1 magnification characteristic that allows focusing the light from the arc into the target light pipe with practically no change in etendue. This results in a more consistent coupling efficiency from burner to burner. Furthermore, for a given etendue requirement the system allows the use of burners with longer arc gaps without degrading the coupling efficiency. Implication is that lamps with longer arc gaps renders to a potential of longer service life, ease in manufacturing, and lower production cost. This paper presents the ASAP simulations and experimental results as they are applied to projection systems. |
