Abstract

Increasing frame rates and the heat sensibility of test objects forced the development of new lighting systems. For example at the automotive industry, where continuous light sources are indispensable for the high speed photography of car crash tests and automobile components tests, the further development of high efficient safety systems, so as Air-Bag systems, needs very datailed analysis of the accelerated motions. Frame rates from 2.000 up to 10.000 frames per second are requested and beside adequate camera systems and film material, this also means high intensive lighting systems. The need for high intensity could be easy achieved by the use of additional light fixtures but the request for more intensity comes along with the problem of heat. The test objects and the auxiliary materials become more and more temperature- sensitive. Very offen they have to be used under strict climate conditions. Mainly there where the test objects are already placed inside the illuminated area, the heat radiation of the light sources to the test objects have to be reduced. So high intensive, flicker free and less heat are today's requirements of light performance. This paper will present solutions to meet those demands.
