Zhaga LED driver spec updated

16 August 2017 Opto-Electronics

The Zhaga Consortium, a global association of lighting companies that is standardising interfaces of components of LED luminaires, has published a significantly updated version of its interface specification for LED drivers.

The new specification, designated Book 13 Edition 2.0, aims to reduce complexity in the market by having significantly fewer mechanical form factors than the earlier version. Overall, Edition 2.0 features only 27 categories, compared with 78 in Edition 1.0. Also, Book 13 now addresses the electrical interface between LED drivers and LED modules, which is critical in determining whether components are interoperable.

The reduction in mechanical form factor categories represents consensus on a global basis among leading LED driver manufacturers. Removing unnecessary variations in components is a key feature of Zhaga standardisation, and is highly beneficial for LED driver vendors, luminaire makers and customers alike.

For the module driver electrical interface, Zhaga has chosen to reference specifications from MD-SIG, a global industry consortium. Where drivers and modules are compliant with the LEDset Power Interface specification from MD-SIG, this allows a meaningful comparison of product data to see if the driver module combination is a viable option.

For LED luminaire makers, Zhaga Book 13 allows the identification of suitable LED drivers for a specific luminaire design, both in terms of correct mechanical fit and also to ensure that the LED module operates as intended.
