Goniophotometer for angle-dependent measurement of photometric properties of luminaires.
Equipment
LGS 650 goniophotometer and DSP200 photometer / Instrument systems
CAS 140D array spectroradiometer and LEDGON 100 Goniophotometer / Instrument Systems.
Method
Together with the remote controlled current and voltage sources, power meters and temperature controllers photometric and radiometric parameters of light sources up to 1.3 m length (LGS 650) or up to 112 mm (LEDGON 100) can be determined angle-dependent at a measuring distance of up to 12 m (LGS 650) or up to 70 cm (LEDGON 100).
Expected Result
Accurate determination of the luminous intensity distribution and luminous flux and of angle-dependent radiometric, photometric and colorimetric parameters to characterize all types of light sources with export to Excel, IES and Eulumdat.
Case Study
A luminaire manufacturer wants to evaluate angle-dependent parameters of prototypes.
