Abstract

In our contribution, we discuss an optical system which is able to provide sun-like radiation on a CPV module. This system is able to realize collimated light with more than 130 klx, with an angle of incidence of less than 0.26°. Special attention is given to a uniform light distribution on an illuminated area of 8 × 8 inches. The resulting optical efficiency of the system is 33%, much better than previously achieved with Xe flash lamp designs [1]. The design is based on a P-VIP 330/1.0 lamp, the latest in a series of OSRAM's P-VIP lamp types for video projectionwhich is featuring a peak luminance of approximately 9 Gcd/m². As a result of the enormous operating pressure of the lamp, its spectrum is similar to the spectrum of the sun and will probably enable at least a class B simulator. The device based on the described design delivers continuous, sun-like radiation. This way, features of CPV modules as efficiency, angular sensitivity or tracking behavior can be tested during development or even in production.
