LighTimes: UL, Dekra, and VDE Named Authorized Test Labs for Latest Zhaga LED Interface Specifications (Books)

19 Jun 2013

June 18, 2013…Zhaga has reportedly authorized three test laboratories, Dekra, UL and VDE, to issue test reports for Books 4, 7 and 8. UL (Underwriters Laboratories) of Northbrook, Illinois, announced that it has been named an authorized testing laboratory for three new Zhaga Books; Zhaga Interface Specification Book 4: High-intensity LED light engines, Zhaga Interface Specification Book 7: Indoor light engines with separate electronic control gear and Zhaga Interface Specification Book 8: Socketable LED light engine with integrated control gear (85 mm base).

Zhaga is an industry-wide light engine certification standard to help enable the interchangeability of LED light sources made by different manufacturers.The Zhaga Consortium has started certification for products designed according to several more of the Zhaga Interface Specifications, which are known as Books. Certification is now available for Book 4, Book 7 and Book 8. Each Book covers a different type of LED light engine, which the consortium defines as the combination of an LED module and the associated electronic control gear (also known as the LED driver). The specifications define the interfaces between the LED light engine and an LED luminaire.

“UL is proud to be a trusted authorized Zhaga Test Center and member of the Consortium Steering Committee,” said Todd Straka, global director, UL Lighting. “These additional book authorizations illustrate our growing commitment to assisting in the global adoption and use of high-quality and efficient LED Lighting products,” added Straka.

Zhaga standards cover the physical dimensions, as well as the photometric, electrical and thermal behavior, of LED light engines. Standardization is expected to prevent market fragmentation into incompatible products.

Book 4 defines the interfaces of a type-D LED light engine (non-socketable LED module with separate electronic control gear). This LED light engine is intended for applications that need a high-intensity light source, such as street lighting and industrial high-bay applications. Book 4 specifies a rectangular light-emitting surface in three variants, 30 mm x 7.5 mm, 42 mm x 10.5 mm, and 60 mm x 15 mm.

Book 7 defines the interfaces of a type-D LED light engine (non-socketable LED module with separate electronic control gear). Book 7 includes a range of indoor LED light engines with different form factors and is intended for applications such as indoor office lighting.

Book 8 defines a socketable light engine with integrated control gear – mainly used in downlight applications.

These three new book accreditations add to the two books UL is already authorized to test for; Zhaga Interface Specification Book 2: Socketable LED light engine with integrated control gear (65-mm base) and Zhaga Interface Specification Book 3: Disc-shaped LED module with 9-23 mm light-emitting surface.
