Zhaga releases Book 12 specification for COB LED arrays
Book 12 defines a family of six rectangular and square LED modules with a circular light-emitting surface (LES). The 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).
Three test labs – DEKRA, Intertek and VDE – are authorized to perform testing procedures that will enable manufacturers to certify their COB products according to Zhaga Book 12. All certified products are listed in Zhaga’s online database.
