Zhaga starts work on new Book for COB LED arrays

Posted on Wednesday December 10 2014, by Tim Whitaker

The Zhaga Consortium, which develops specifications for interchangeable LED light sources, is now working on a new Book that will include Chip-on-Board (COB) LED arrays.

COB arrays are already in widespread use throughout the LED lighting industry, but different manufacturers offer a wide range of alternative sizes. This creates problems for luminaire makers and other stakeholders such as COB holder suppliers, and limits their options to use alternative products from different suppliers without changing their luminaire or holder designs.

“We consulted many luminaire makers, and received broad support for our plans to standardize this type of LED light source,” said Musa Unmehopa, Secretary General of the Zhaga Consortium. “These companies asked us to standardize properties such as the mechanical dimensions of the module, the position of electrodes, and the diameter of the light-emitting surface.”

After extensive discussion it was decided to specify a family of six rectangular or square modules, with the following PCB dimensions: 12 x 15 mm, 16 x 19 mm, 19 x 19 mm, 20 x 24 mm, 24 x 24 mm, and 28 x 28 mm.
