Advanced Services

Optical design verification

EBV offers our customers a wide range of measurements on a lighting products portfolio offering the entire range of highly professional devices
The list of the measuring devices includes two integrating spheres for 2π and 4π measurements, a spectroradiometer for reference measurements, a goniophotometer, a light density measuring device and a luxmeter. This product range is complemented by special measurement/evaluation and control software among others.
 

  • Measuring on Level 1 (LED packages), Level 2 (LED modules) and Level 3 (luminaires)

  •  Radiometric and photometric quantities


           radiant power [W], radiant intensity [W/sr], irradiance [W/m²], radiance [W/m² sr]
           luminous flux [lm], luminous intensity [cd], luminance [lx], luminance [cd/m²]
           EBV helps with measurement and verification of customer‘s luminaire quality parameters, LED data sheet and bin verifications and EULUM.DAT file creation for simulations. Furthermore, EBV is able to compare performance parameters of different manufacturers and has built up a data base

  • Spectral parameters


           dominant wavelength, spectral width
           The dominant wavelength and purity determine the LED‘s colour, so an analysis of influences modifying them is key. EBV helps with verification of driver/driver signal that might cause shifts, ageing phenomenon.

  • Colorimetric parameters Image of Colometric parameters
           chromaticity coordinates, CRI (Color Rendering Index), Correlated Colour Temperature (CCT) and also GAI (Gamut Area Index), CQS (Color Quality Scale) for chroma/saturation, tint and lightness analysis
           EBV can provide the industry standard GAI value if the LED manufacturer isn‘t stating these in data sheets.
