Large-format goniophotometer LGS 1000

for solid-state lightingfor LED modules

Goniophotometer for large SSL/LED modules Determining spatial radiation properties of large samples The LGS 1000 is ideally suited to precise determination of the angle-dependent spatial radiation properties of large and heavy LED modules, solid-state lighting (SSL) products as well as conventional lamps and luminaires. It can be operated either together with a photometer as a classical goniophotometer or with a spectrometer, e.g. the CAS 140D, as a high-quality and extremely versatile goniospectroradiometer. In this way, all key parameters such as luminous intensity distribution, luminous flux, color coordinates and even the color rendering index can be measured with the greatest accuracy. The instrument is suitable for samples with a diameter up to 2 m and weight of up to 50 kg. In combination with a photometer extremely fast measurements can be performed “on-the-fly”. The spatial light distribution of the sample is determined in the shortest possible time, while the goniophotometer in motion. Extensive features of the SpecWin Pro software facilitate the evaluation and preparation of the readings.
