The Zhaga Consortium  has published its second interface specification for LED light engines. Zhaga Interface Specification Book 2 can now be downloaded from the organization’s website (http://www.zhagastandard.org/specifications/book-2.html ).
In addition, Zhaga has created a database of certified products that are all commercially available. The database will be constantly updated as new certified products reach the market.
Zhaga is an international consortium of companies from the lighting industry whose main role is to develop interface specifications (known as Books) that enable the interchangeability of LED light engines made by different manufacturers.
“The publication of Book 2 provides full access to this specification for the entire lighting industry, not just Zhaga members, allowing companies to design their products to be interchangeable with other Zhaga-based products,” says Menno Treffers, Secretary-General of the Zhaga Consortium.
Zhaga Interface Specification Book 2 describes a cylindrical, socketable LED light engine with integrated electronic control gear (ECG). The light engine has maximum dimensions of 70.2 mm by 45 mm. The diameter of the circular light-emitting surface is typically 59 mm. The light engine can be locked into a holder in the luminaire by means of a twisting motion.
One use of this type of LED light engine is in downlighting applications. A summary of the technical details of Book 2 can be found on the Zhaga website along with the full specification.
Products designed and certified according to Zhaga Interface Specification Book 2 – including LED luminaires, LED modules, holders and LED light engines – are already commercially available from a range of different suppliers.
“The availability of Zhaga-certified products demonstrates that the specifications developed by Zhaga are being utilized by a range of companies in the lighting industry,” Treffers says. “Other products are currently going through the certification process, and we expect to add many more products to the database in the coming months.”
