Compact goniophotometer LGS 350

for LED modulesfor luminaire

Compact, space-saving goniophotometer Spatial characterization of medium-sized SSL light sources and LEDs The LGS 350 goniophotometer or goniospectroradiometer was developed by Instrument Systems for determining the angle-dependent spatial radiation properties of small to medium-sized SSL luminaires and LED modules. The light source is operated in a horizontal burning position and can be measured in an angle range of ±160° to the mechanical axis. Together with an Instrument Systems spectroradiometer, all spectral parameters such as color coordinates, color temperature and even color rendering index are determined angle-dependent. Photometer DSP 200 can also be used for fast “on the fly” measurement of C-levels. The instrument is suitable for samples with a diameter of up to 700 mm and a weight of 8 kg. LGS 350 – Highlights: - Type C goniophotometer for test samples with a diameter of up to 700 mm and a weight of 8 kg - Precise determination of luminous intensity distribution and luminous flux - Angle-resolved examination of spectral and colorimetric quantities - Data export in IES and EULUMDAT format - Easy and intuitive control of the measurement process, as well as power supply and electric measurement of the sample - Configurable switch-on and stabilization routines for the light source in repetitive measuring tasks - Extensive and adaptable measurement logs and reporting functions Thanks to its universal sample holder, the LGS 350 is suitable for a wide range of measurement tasks on medium-sized LED modules and luminaires. In addition, it has a sample holder for LED-850/LED-870 TEC adapter and standard lamp base E27.
