LED light engine with integrated electronic control gear

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.In addition, Zhaga has created a database of certified products, which 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 throughout the lighting industry. Its 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,” said 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.The light engine has maximum dimensions of 70.2 mm and 45 mm height. 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.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,” said Menno Treffers. “Other products are currently going through the certification process, and we expect to add many more products to the database in the coming months.Each interface specification, or Book, is developed by cooperation between the member companies of Zhaga. Once the certification procedure is in place for a particular Book, and once the first certified products have been sold, then Zhaga’s policy is to publish the full specification.

Only products that have been through the full Zhaga test and certification procedure, which is performed by third-party laboratories, are entitled to use the Zhaga logo. Non-members are able to use the published specifications to design Zhaga-based products, but they cannot have their products certified unless they join Zhaga.The increased service life of the components in operation is due to the use of nanoparticles of one size only. This enhances the stability of the sensitive thin-film components. Short circuits due to oversized particles are excluded.The development made by the researchers from Karlsruhe and Toronto is also characterized by an impressing homogeneity of the luminous areas. The KIT researchers are among the few teams in the world that know how to manufacture such devices.
