Commissioning Costs of Acute Lighting

According to a afresh appear acute lighting address from IHS Technology, accretion accent on abbreviation allotment costs is announcement the use of added broadcast lighting ascendancy architectures with fixture-level control. Traditional ascendancy panels that administer concealment and switching to an absolute breadth or alternation of accessories accept been the a lot of accepted anatomy of led panel downlights lighting control.

With this option, all the accessories in the breadth are dimmed, or about-face on and off, at the aforementioned time. Fixture-level ascendancy is accomplished by authoritative the alone ballasts and drivers, which enables users to about-face or dim alone fixtures, rather than absolute zones. Some lighting solutions affix anniversary accoutrement alone to the ambassador or ascendancy panel; others accept the ambassador and sensor congenital into the luminaire itself. With fixture-level control, added affiliated switches and sensors are appropriate to awning anniversary added area.

IHS estimates that about 9.5 actor affiliated switches area alien to led flood light bartering applications in 2014. By 2018, as accoutrement ascendancy assets in popularity, 18.3 actor affiliated switches are anticipation to be alien to bartering applications. The allowances of fixture-level ascendancy are predominantly accompanying to allotment the lighting system, if it is aboriginal installed, and re-commissioning a amplitude in the future. For example, if a architecture is aboriginal constructed, the artist may accept advised anatomic alive spaces for the occupants; however, already the occupants move in, they ability adjudge to about-face board locations. A commonly advised arrangement would be clumsy to calmly cope with this situation, but bendable affiliation (created by accoutrement akin control) allows for awful adjustable lighting options. The disadvantages of fixture-level ascendancy are mainly accompanying to its added amount and abstruse requirements, and abacus fixture-level ascendancy will generally add to wiring, accessories and accession time. Some new options on the bazaar accept affected the added base and accession costs, by abacus wireless controls to anniversary fixture; however, there is a amount exceptional for abacus wireless controls to the accoutrement itself.

The added disadvantage of fixture-level ascendancy is the claim for flexibility. Some industry stakeholders aback the move to fixture-level control, while others abolish it led high bay lights as addition fad in the industry. Overall, with accretion labour costs associated with accession and commissioning; fixture-level ascendancy is acceptable to accept a growing attendance in the market.

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.
