The ZC Series has been designed to provide high-brightness with decreased thermal resistance for increased product life-expectancy. COB construction eliminates the need for LEDs to be surface-mounted on a metal plate, permitting manufacturers to bypass the chip-connection process before use, and reducing manufacturing cost.
Stanley Electric has introduced the 6J series of high-efficiency multi-die white LEDs, which are designed to meet the requirements of a variety of lighting applications.
Performance specifications include efficacy up to 150 lm/W and a typical CRI of 95. The 6J X-type LEDs feature available CCT of 2700, 3000, 4000, 5000 and 6500K. The 6J Z-type line addresses high color-rendering needs with Ra of 95 and CCT of 2700, 3000, 4000 and 5000K.

The LED arrays consist of 160 LEDs laid out in ten parallel, connected rows of sixteen. The flat surface of the ceramic plate and in-place soldering points make it possible to attach the modules to a suitable heat sink.
|Lustrous N506 Series LED array.|
The N506 series of LED arrays produce a lumen output comparable to that of a 60W incandescent bulb while consuming 6-8W. The warm-white LEDs (3000K) feature a CRI of 90 and efficacy of 125 lm/W. The cool white (5000K) version offers a CRI of 70 and 140 lm/W efficacy.
Bridgelux has introduced its latest generation of LS, ES and RS product families, designed to deliver 30% better efficacy at 30% lower cost per lumen compared to previous products.
The LED arrays offer optical and mechanical compatibility with previous product generations, allowing upgradeability. Greater flexibility in system design is aimed at helping users more rapidly achieve compliance with Energy Star, Title 24, Part L and other global energy-efficiency standards.
The arrays are available in a range of color temperatures from 2700K to 5600K with 3 SDCM color-control options.
|Luminus CBT-90 array|
The CBT-90 includes multiple LEDs on a single chip (3 x 3 mm) and mounted on a metal-core PCB. The array is capable of producing 2200 lm at its top current level. “Our customers developing endoscopy light boxes, now for the first time, have an LED that produces system-level light intensity that rivals the gold standard for endoscopy – the 300W xenon lamp,” said Chuck DeMilo, Global Director of Product Marketing for the Lighting Business Group at Luminus Devices.
