Instrument Systems showcased the LGS 350 goniophotometer to demonstrate applications for the highly accurate and fast testing of medium-sized LED modules according to the EU Eco-Design Directive. The newly optimized design of the LGS 350 system was presented for the first time at Light + Build 2016 which features an 85% increased travel speed of the γ-axis to 34°/s. The permissible top speed of 0.25 m/s pursuant to CIE S 025 is thus possible for a large number of LED sample sizes. Compared to present measurement solutions, for the user this means greatly increased throughput while maintaining a high standard of measurement precision. With an add-on module of the established SpecWin Pro software, a broad range of ErP tests is available for the preparation of test reports according to the EU Directive.
