LGS 1000 - Superior measurement technology for large SSL lamps and LED modules
The new LGS 1000 goniophotometer or goniospectroradiometer analyzes the angle-dependent spatial radiation properties of large SSL lamps and LED modules up to a length of 1900 mm and weight of 50 kg. The Type C design with horizontal optical axis permits a much simpler setup for the measuring path – despite its impressive dimensions of 1850 x 1492 x 1798 mm – than with complex mirror goniophotometers.
Combined with a spectroradiometer from Instrument Systems, all spectral quantities such as color coordinates, color temperature and even color rendering index can be determined as a function of angle. C-plane measurements can also be carried out very quickly “on the fly” using the Optronik DSP Photometer.
The complete system
The LGS 1000 comprises the goniometer with a sample plate for fixing the test specimen and the LGS Controller. The goniometer also features accessible steps for much easier mounting of test specimens. The LGS Controller is integrated in a large 19” rack. The controller drives the servo motor and displays the angle. It also shows the measured values in candela or lux as necessary.
Product highlights:
Type C goniophotometer for specimens up to 1900 mm in diameter
Accessible steps facilitate mounting of samples
Accurate determination of luminous intensity and luminous flux
Angular-resolved analysis of spectral and colorimetric quantities
Optional luminous flux integrator
