The large-area spray deposition method employed for this new process provides maximum processing flexibility as well as scalability.
According to Paul Lindner, executive director of technology at EVG, “The large-area spray coating technology used in this process has been in commercial production in the display technology space for well over ten years. This field-proven equipment solution, combined with BMT’s novel material, allows us to quickly and uniformly coat nano-scale films onto a large number of luminaires, a key requirement to meet the challenging volume and cost targets of our LED customers. In addition, spray coating allows for coating over a large range of form factors. For instance, lenses with highly curvilinear features, which is another important requirement for the LED luminaire market.”
Soraa Gen3 LED breaks barriers
The GaN on GaN innovator has achieved a 30 percent lumen/W increase over the previous generation Soraa has announced it has made the world’s most efficient LED, which it will integrate into the market’s first full-visible-spectrum, large form factor lamps. Soraa says its third generation (Gen3) GaN on GaN LED achieves world-record setting wall-plug-efficiency, outperforming the nearest competitor by 20 percent at normal operating conditions.
powered by its Gen3 LED, will lead the market not only in light output, but also in colour and whiteness rendering; at CRI-95 and R9-95 it will achieve centre-beam intensity (CBCP) of 28,250cd at 8° beam angle, 10 percent higher than the CRI-85 offering of the nearest competitor. Soraa claims its large form factor lamps will feature natural and accurate rendering of colours and whiteness, perfectly uniform beams of exceptionally high intensity, and clear single shadows. «Soraa›s Gen3 GaN on GaN LED package is a major milestone for the LED industry and a truly disruptive innovation. We have achieved a 30 percent lm/W efficiency improvement over our previous generation white LEDs, and what›s amazing is that we expect to repeat these significant year-over-year performance gains in the future,» says Jeff Parker, CEO of Soraa.
The company›s Gen3 LED runs at 75 percent wall- plug-efficiency at a current density of 35A/cm2 and a junction temperature of 85°C, efficiency levels that are out of reach for other LED manufacturers. With a proprietary three-phosphor combination, Soraa says its Gen3 LED emits full-visible-spectrum light (all the colors of the rainbow, including violet), which excites optical brightening agents and perfectly renders whiteness as well as colours.
Plessey appoints ex Cree sales officer as CCO
With a new man on the block, the firm’s aim is to drive global uptake of its patented GaN-on-silicon technology as a cost-effective alternative to existing lighting systems, and expand its UK manufacturing facilities
As it gears up to grow global sales of its LED technology, Plessey Semiconductors of Plymouth, UK has appointed Jose (Joe) Lopez as chief commercial officer (CCO).
Reporting to Plessey’s CEO Michael LeGoff, he will assume overall responsibility for the commercial and customer aspects of the organisation, with the main focus being to grow Plessey’s LED sales.
Soraa›s GaN on GaN Gen3 LED
In a year, Soraa has achieved a 30 percent increase in white lumen per watt (lm/W) efficiency over its prior generation LED, setting a pace of technology evolution which it believes is unrivalled in the LED industry. Soraa›s Gen3 LED will be available in the second quarter of this year in a variety of product offerings: modules, large form factor PAR and AR lamps, and MR16 lamps.
