Zhaga publishes Book 12 on COB LED arrays
Posted on Friday March 4 2016, by Zhaga
Zhaga has now published its eagerly-awaited specification on chip-on-board (COB) LED arrays. Zhaga Book 12 can be downloaded from the Zhaga website. Download Book 12
Book 12 defines a family of six rectangular and square LED modules with a circular light-emitting surface (LES). These modules require a separate LED driver, and can be used either with or without holders, depending on the luminaire type and application. Most Book 12 modules will use COB technology for the light-emitting section.
By defining a small family of COB form-factors, Book 12 removes arbitrary variations in non-competitive properties such as outer dimensions and electrode positions. This reduces the complexity of luminaire development, and simplifies the supply chain for luminaire manufacturers. For COB makers, standardization of non-competitive properties allows them to focus on areas where they can add value, such as efficacy or lifetime (which are not included in the Zhaga specification).
