Standardizing interfaces for LED Light Engines (LLE) is an objective of the Zhaga consortium, an association of companies in the lighting industry. The basic idea is to live up to the quick innovation and development cycles, make the wide variety of different LED modules combinable with each other and thus, continue to drive forward LED technology.
LED light engines consist of at least one LED module, which can be combined with a control gear, if necessary. The goal is to standardize the LED light engines, e.g. the mechanical, thermal, electric, and photometric interfaces, to make them exchangeable. It should be implemented both for newly developed, efficient generations and for different manufacturer products. Zhaga develops specifications, called books, to achieve this standardization, and member companies can voluntarily use these specifications. However, the goal is to carry over the books into the international IEC standards.
Zhaga has developed a proprietary testing and certification process to test products for their conformity with these specifications. After successful testing, a Logo License Administrator (LLA) issues member companies of the Zhaga consortium a certificate, which grants the right to display the Zhaga logo. It requires the appropriate licensing agreement with the LLA and being a Zhaga member company. Furthermore, the rules stipulate that only authorized test laboratories that have signed a “Testing Center Agreement” may perform the tests. As an authorized test laboratory, the VDE Institute can therefore perform any tests on LED products according to the corresponding Zhaga books.
