Zhaga standard drives LED lighting breakthrough

April 18, 2012 // By Christoph Hammerschmidt
At Light + Building, a number of manufacturers including Osram and Toshiba introduced first implementations of LED light engines meeting the Zhaga standard. Zhaga defines the mechanical, electrical and thermal parameters to make light engines exchangeable.

At its booth, Osram showed the Prevaled Core Z2 spot light which features an efficiency of 108 lm/W. In addition, the Siemens subsididary also showed the rod-shaped Prevaled Linear and Prevaled Linear Slim modules designed for office and industrial applications. Toshiba showed a Zhaga-compliant light engine for downlight applications without providing more details as to the electric and photometric variables of the devices

Light engines in the sense of the Zhaga consortium contain LED modules, associated optics, power connections, driver and heat management, all in an exchangeable module. Also certain photometric parameters are standardized within the scope of the Zhaga standards. This set of definitions makes light engines as easily exchangeable as conventional light bulbs or fluorescent lamps.

The quick innovation in the LED lighting market has made standardization a necessity. Consequently, this quick succession of LED module generations required a new luminaire design for almost every LED generation. In order to improve this situation, about 180 companies worldwide formed the Zhaga consortium.

According to a Zhaga press release, there were about 30 companies that introduced Zhaga-compliant products at the fair.
