The international Zhaga Alliance recently released the cylindrical, embedded LED spotlight interface specification Book 2, which provides suppliers with a modular approach to interoperable SSL luminaire design . The Zhaga Interface Specification Book 2 defines the Solid State Lighting (SSL) module, which is primarily used for the specification of the downlight application interface, and has created a certified product database that is commercially available. The Zhaga Interface Specification describes a cylindrical, embedded LED light engine integrated electronic control unit (ECG), commonly referred to as a driver. The light engine has a maximum size of 70.2 mm and a height of 45 mm. The circular luminous surface is usually 59 mm in diameter. The light engine can be locked to the torsional motion device of the luminaire. One of the uses of this type of LED light engine is spotlighting. Menno Treffers, secretary general of the Zhaga Alliance, said: "The publication of Book 2 not only provides a complete specification for the entire lighting industry, but also allows design companies to exchange their Zhaga-based products when designing their own products." In October 2012, Zhaga released Book1 and Book3, which define common and generalized specifications for all different interfaces, with a separate ECG, circular light-emitting surface diameter between 9 and 23 mm. Interface definition between plug-in LED light engines. Zhaga has approved several other specifications (Books 4, 5, 6, 7, and 8), but currently only for Zhaga members. Other specifications are also being developed. Zhaga members can perform a full Zhaga test and certification process through a third-party laboratory, using the Zhaga logo right away, while non-members can use Zhaga-based specifications to design products, but not the Zhaga logo unless they join Zhaga.
