Lighting Tech in Space Tests
Thursday, 24 May 2001
From a situation where an almost unknown client would purchase the occasional lamp, Lighting Technology has found itself supplying equipment for space equipment testing, with lighting units from Arri key to the project. With help from Mike Perry of Arri, Lighting Technology’s Jonathan Price and Andy Dodd demonstrated the Arrisun 60 6kW HMI fixtures to TS Space Systems of Marlow, who have since ordered the units for one of their test programmes. The company designs and builds test equipment for acceptance of materials and sub-assemblies for spacecraft, with space simulation chambers, ion thruster chambers and testing of solar cells and panels.

TS Space Systems’ Bill Williams said: "As part of the tests for UV ageing of materials, most tests have up to now used DC xenon or mercury arc lamps. However, HMI lamps have come on in leaps and bounds, are lower in cost, involve no water cooling, and provide roughly twice the light output. For the tests involved we run a twin 6kW system, whereby should a lamp fail, a motor-driven unit automatically moves the failed unit away and brings the other unit into play."

He continued: "We are delighted with all the help and technical support received from Lighting Technology. The tests are now successfully under way and the units are providing an excellent spectrum and level of intensity."
