ASIA’S MOST ADVANCED LED TEST CENTRE
“Without light, we won’t see anything,” says Hanson
Zhang, switching on the lighting for the photobiological
safety test room. The walls and ceiling are
painted black. On a long workbench, also painted black,
three high-tech devices, some rails and a computer
monitor have been strategically placed. “For our new
laboratory I was able to choose and calibrate the equipment
myself and define the test process together with
my colleagues in Arnheim, in accordance with IEC
guidelines,” explains Zhang. A trace of pride is evident
in his voice, which is understandable given the pioneering
role he has played in the field of LED tests in Asia,
significantly enhancing the reputation of DEKRA
Testing and Certification Centre China in the process.
It is the first laboratory of its kind in Asia, enabling
DEKRA to test and certify the photobiological safety
of new light systems, in particular the new LED lights
which are set to play such a major role.
Two storeys below, on the ground floor, are the other
12 test rooms of the centre with their light-coloured,
six metre-high walls and precisely arranged test rigs.
Hanson Zhang oversees an average of up to seven tests
at any one time. “Performance tests for lighting units
can take up to three months and more,” explains the
measurement engineer, indicating an array of halogen
bulbs laid out in long rows. His day starts and ends
at very different times, depending on the tests being
performed. “I am often in the lab at five in the morning,
and sometimes we don’t finish a test until late at night.”
As the expert responsible, Hanson Zhang writes up the
test reports and discusses the results with his customers
and colleagues.
