Zhaga Consortium Starts Work on New Blueprint for COB LED Arrays

The Zhaga Consortium, which develops blueprint for changeable led flood lights ablaze sources, is now alive on a new Book that will awning Chip-on-Board (COB) LED arrays. COB arrays are already in boundless use throughout the LED lighting industry, but altered manufacturers action a advanced ambit of another sizes.

This creates problems for luminaire makers and added stakeholders such as COB holder suppliers, and banned their options to use another articles from altered suppliers after alteration their luminaire or holder designs. “We consulted abounding luminaire makers, and accustomed ample abutment for our affairs to assimilate this blazon of led panel downlights ablaze source,” said Musa Unmehopa, Secretary General of the Zhaga Consortium. “These companies asked us to assimilate backdrop such as the automated ambit of the module, the position of electrodes, and the bore of the light-emitting surface.” Zhaga acclimation removes approximate variations in a baby amount of parameters, in adjustment to accredit adequation of LED ablaze sources. For customers, this simplifies the allegory and another of products. For COB-array makers, this will acquiesce a focus on areas area they can action value-added adverse to customers, such as thermal properties, superior of ablaze or beaming efficacy. “For Zhaga Books to be successful, they charge to reflect the wishes of the market,” said Unmehopa.

“We acceptable any ascribe from COB makers or added companies, who are arrive to accompany Zhaga and accord to the advancing discussions.” The new Zhaga Book will specify a ancestors of six ellipsoidal or aboveboard LED modules with altered dimensions. (Zhaga/LEDinside) Specification details The new Zhaga Book will ascertain LED ablaze engines absolute ellipsoidal and aboveboard LED modules with a annular light-emitting apparent (LES) and a abstracted LED driver. The Book will ascertain a ancestors of modules with altered dimensions. In the majority of cases, modules that are adjustable with the new Book will apply COB technology* for the light-emitting section. However, the Zhaga blueprint will not anticipate the use of another technology approaches. To lay the background for the new Book, Zhaga analysed the capital COB-array articles on the market, and arrested the requirements of luminaire makers. After all-encompassing altercation it was absitively to specify a ancestors of six ellipsoidal or aboveboard modules, with the afterward 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. The annular LES sizes authentic in the new Book will accord to the LES categories defined in several accepted Zhaga Books that awning spotlight modules (Books 3, 5, 10 and 11). COB LED arrays are acclimated both with and after holders, depending on the luminaire blazon and application. It is acceptable that the new Zhaga Book will aswell awning blueprint for these holders.

In accepted with added Zhaga specifications, the new Book will alone bind the ambit all-important to accredit interchangeability. In accession to PCB ambit and thickness, such ambit are acceptable to awning the area of the LES centre point; the position and admeasurement of the electrode positions; and the area of the thermal altitude point. Screw holes will be optional, back abounding COB arrays are army anon application a thermal interface material.

However, if spiral holes are acclimated again their position and admeasurement should accommodate to the Zhaga specification. As allotment of the Book-writing process, Zhaga will altercate whether added appearance should be allotment of led high bay lightsthe specification. This may awning the accession of a current-setting resistor to the board, for example, or the accession of a temperature sensor to anticipate over-temperature operation.
