Photometry is the science of the measurement of light, in terms of its perceived brightness to the human eye.
Our luminaires are tested using goniophotometers, which keep the luminaire stationary at a sufficient distance from the photocell that the luminaire can be considered a point source. Goniophotometers use a rotating 2-axis table to change the orientation of the luminaire with respect to the photocell. From the photometric data it is possible to produce light technical data according to utilized standards and applications.
The data serve as basis for lighting calculation programs in which entire rooms, fitted with diverse luminaires, are calculated and evaluated, exact illumination design plans can be produced.
All photometry is executed according to the EN13032-1 and CIEs (International Lighting Commission) regulations and guidelines.
A flash measurement unit with computer-supported evaluation of the flash pulses and assessment of the effective luminous intensity completes this facility. With our transportable testing units, we are also able to perform measurements of luminous intensity and light density in the field.
