At PERFORMANCE IN LIGHTING there are several laboratories available that
permit manifold inspection and testing of our luminaires as early as the
development phase. This shortens the development period, since early
concrete assertions can be made about the properties of the luminaires,
and guarantees the highest quality and reliability while they are still under
development. All the parameters are tested which are important for the
operation and safety of a luminaire.
Inspection Technology
Thermal Laboratory
The luminaire test facility is installed in a specially climatised laboratory
for a wide range of thermal measurements on luminaires and operating
devices. PERFORMANCE IN LIGHTING uses this warming test facility to
check whether a luminaire fulfls the thermal requirements named in DIN
EN 60598. Durability under warming in normal and abnormal operation
is likewise checked, using e.g. the F measurement. There is also a special
stress lab available, e.g. for tests in higher ambient temperatures. In
addition, measurements for special client requirements can be carried out,
or luminaires tested and measured on behalf of clients.
Apart from this, there is also a facility for image resolution temperature
measurement – the ascertaining of heat distribution by thermography.
The thermal laboratory has received TDAP certifcation from the VDE
test and certifcation institute. This documents the high quality of the
measurements in our temperature laboratory and allows us very close
cooperation with the VDE.
interference. The applicable standard for this is DIN EN 55015
(VDE 0875-15-1). The real time spectrogram mode makes it possible to
search for causes and solutions of EMC problems in real time – as early
as the development stage of the product.
Compliance with the EMC requirements according to the EMC directive is a
foundation for the legally prescribed CE marking of our products.
EMC Laboratory
An EMC laboratory is installed in a separate, specially shielded room.
Electromagnetic compatibility (EMC) measurements are undertaken here
using the CDN method according to CISPR with the latest technology
based on a fast Fourier transformation (FFT) flter bank. This technological
advance on traditional test receivers makes it possible to carry out
measurements many times faster and in fact continuously in real time.
The aim is to comply with the limit values for immunity and emitted
Photometric Laboratory
There are two separately equipped standardised black laboratories available
for photometric measurements. This is where during development and on
client request the photometric properties of our luminaires are measured
and optimised. Luminosity distributions according to DIN 5032 and
other relevant data such as glare assessment and luminaire efciency are
recorded here with computer assistance.
There is an integrating sphere available for precise determination of the
luminous fux of illuminants. This is a precondition for the correct
determination of luminaire efciency. Luminaires that work independent
of location and high-performance luminaires are measured with a high-
precision goniophotometer.
Luminaires that are sensitive to changes of location are measured with a
Riemann goniometer. This cutting-edge technology based on image
resolution near-feld goniophotometry with CCD measuring technology
permits the measurement of luminaires far within the photometric limit
distance without changing the location of the luminaires to be measured.
As well as light distribution the equipment also provides luminance
information and radiation data.
