Zhaga is a consortium initiated in 2010 to address the issues of LED lighting and its standardization. It is active worldwide and already had over 200 member companies at the end of 2012.
The goal of the Zhaga consortium is to ensure the interchangeability and compatibility of LED lamps among the many manufacturers. To this end, Zhaga defines the interfaces for the various lighting fixtures and sockets. This includes the physical dimensions of the lamp sockets, as well as the photometric, electrical and thermal behavior of the light-emitting diodes and LED luminaires. Standardization makes the products offered comparable, which benefits both the manufacturing industry and consumers because it makes the products interchangeable.
Zhaga uses the term LED light engine in connection with the standards it has developed to refer to the LED luminaire consisting of the light-emitting diode and the mechanical, electrical, photometric and heat-dissipating components surrounding it. As for interchangeability, this is when one LED lamp can be replaced by another without changing the illumination. The Zhaga Consortium has published several books. Book 9, for example, deals with LED modules, describing their shape and size. Book 12 defines rectangular and square LED modules with light emitting surface in CoB technology, Chip on Board (CoB) and Book 13 contains information about LED drivers that can be used with LED modules.
LED products certified by Zhaga may be marked with the Zhaga logo.
