Zhaga is an international industry-wide consortium for standardisation of LED lights with specifications aimed at ensuring the interchangeability of LED light sources from different manufacturers.
Zhaga specifications, known as Books, describe the interfaces between luminaires and LED light sources. The interface specifications cover the physical dimensions as well as the photometric, electrical and thermal behaviour of LED light engines.
LED luminaire manufacturers benefit from multiple suppliers of interchangeable LED light sources, while LED light engine manufacturers can leverage increased volumes of standard products.
Zhaga specification makes products more future-proof for large industrial end-users and municipalities. It also simplifies repairs, refurbishment and upgrades.
TÜV SÜD is a fully recognised and accredited Zhaga test centre that performs various compatibility, thermal, electrical and photometric tests and certifications. We also perform safety, EMC, energy efficiency and chemical tests.
TÜV SÜD’s testing and certification services for Zhaga include:
- Interchangeability - TÜV SÜD tests and certifies LED luminaires and LED light engines according to Zhaga specifications. These specifications enable the interchangeability of LED light sources made by different manufacturers.
- Photometric interface - We conduct photometric tests concerning the parameters of the light-emitting surfaces: their dimensions, position and orientation, as well as the LED light engine’s luminous output, luminous intensity distribution and luminance uniformity. Other important parameters tested are the beam angle and correlated colour temperature.
- Mechanical interface - Mechanical interface testing checks the correct dimensions, positioning of contacts, coded keys and fixing methods of the light engine and holder.
- Failure analysis - In addition to yielding comprehensive and in-depth analyses, our independent investigations can reveal root causes of failures. These analyses lead to solution proposals for preventative measures to avoid product failures that might result in hefty disputes and compensations.
