Cree Redefines High Power LEDs for Lighting with New SC5 Technology Platform Doubling Light Output to Radically Lower System Cost.

http://www.businesswire.com/news/home/20141023005064/en/Cree-Redefines-High-Power-LEDs-Lighting-SC5


DURHAM, N.C.--(BUSINESS WIRE)--Cree, Inc. (Nasdaq: CREE) achieves another fundamental breakthrough in lighting-class LED performance with the groundbreaking SC5 Technology™ Platform. The new platform powers the next generation of lighting with the introduction of Extreme High Power (XHP) LEDs. This new class of LEDs can reduce system costs by up to 40 percent in most lighting applications.

“As a technology company, we’re focused on breaking the performance barriers that really matter to the lighting industry,” said Chuck Swoboda, Cree Chairman and CEO. “The SC5 Technology™ Platform redefines what is possible in high-power LEDs by doubling the lumens out of a single LED, giving lighting manufacturers the flexibility to innovate significantly lower cost systems. This new platform establishes a new benchmark for LED lumens per wafer, which we believe will define the long-term success of our industry. This also validates our belief that high-power LED technology enables the best lighting system designs and a better lighting experience for end customers.”

The SC5 Technology Platform is built on Cree’s industry-best silicon carbide technology and features significant advancements in epitaxial structure, chip architecture and an advanced light conversion system optimized for best thermal and optical performance. With these advancements, the SC5 Technology Platform achieves unparalleled lumen density and longer lifetime at higher operating temperatures than previous LED technology, which can significantly reduce thermal, mechanical and optical costs at the system level.


“LEDs are no longer the most expensive portion of an LED lighting system, but they fundamentally determine the overall system performance and cost,” said Dave Emerson, vice president and general manager for Cree LEDs. “While other LED manufacturers only promise incrementally lower LED cost, our new Extreme High Power (XHP) LEDs leveraging the SC5 Technology™ Platform directly address the increased burden that thermal, mechanical and optical elements now place on total system cost.”

The first available family of XHP LEDs is the XLamp® XHP50 LED, delivering up to 2250 lumens at 19 watts from a 5.0x5.0 mm package. At its maximum current, the XHP50 provides twice the light output of the industry’s brightest single-die LED, the XLamp XM-L2 LED, at a similar lumens per watt and without increasing the package footprint. By leveraging Cree’s latest reliability innovations, the XHP50 is designed to maintain L90 lifetimes above 50,000 hours even at high temperature and current.

The case on this also made me laugh, did you all notice there is a 360/450/600 all running the same amount of vero's. How efficient are they when driven at 100watts each?

There is also a 2 vero version at 120W for $330usd.

Metal Case = $18 (large version $28)
Vero29 = $31 each so $62
HLP-60H-42 Drivers = $30 each so $60
4" Heatsinks = $6 each so $12
80mm fans = less than 10$ for both
12v 2a fan power supply = $5

For less than 200$ including misc parts, you could build your own using similar parts but I would just get PC heatsink fan combos and you can definitely get cheaper drivers off ebay.

Meanwell lpc-60-1400 = $20 +/-
fan heatsink combo = $9

If your going to have something that looks like its built in a garage you might as well build it yourself.

EDIT: forgot the lenses but I'm sure there is something here, why not use reflectors though for less photon loss.

Is the mark up worth the effort not to do it yourself?...that is what it comes down to.
Currently no. Plus they are not offering the same parts as you can do yourself. In time I can see the prices dropping and efficiency increasing. Even for high end lights like apachetech and A51. Right now in LED growing world I feel that diy cobs are by far the most cost efficient led solution.

“Since the launch of the original Cree® LED Bulb, consumers are rapidly switching to LED technology,” said Betty Noonan, Cree chief marketing officer. “Our New Cree® LED Bulb goes a step further, delivering even better light performance at a lower price. This new bulb provides consumers a better overall lighting experience which we know drives even more rapid LED adoption.”

The New Cree LED Bulb emits a warm, omnidirectional light thanks to its 4Flow™ Filament Design. This innovation creates a compact, optically balanced light source inside a durable, shatter-proof housing. The metal heat sink has been completely replaced with this filament design, which draws the cooler ambient air through the bulb to vent the heat into the ambient to achieve thermal equilibrium, explained Cree. This makes the bulbs much lighter and reduces production costs. The number of LEDs used int he bulb was also reduced by 20% from 10 to 8 with the new 4Flow™ Filament Design and LED improvements from SC5 Technology platform.

The New Cree LED Bulb is available in 40-and 60-watt replacement options, delivering 460 lumens for the 40-watt replacement and 815 lumens for the 60-watt replacement in soft white (2700K) and daylight (5000K) color temperatures. Backed by a three-year warranty, the New Cree LED Bulb consumes up to 85 percent less energy* during its 25,000-hour lifetime and is dimmable.

Whoa whats going on here? Why such a poorly put together kickstarter campaign?

And why did Chris Lam put this up personally rather than the Innoled company?

I am still trying to piece together whether Innoled has any IP, since it appears that Alta is their manufacturer, and Alta already has a very high CRI platform. At best, I am thinking they have a pending patent on their high CRI phosphor blend with a little bit of quantum dots thrown in there, and is having Alta contract manufacture the whole thing....

LED Eco Lights' Goodlight LED SON-style lamps use MagLev fan technology for thermal management
October 2, 2014


Pioneering the use of MagLev fan technology with LED in a UK first, the new range of Goodlight G360 LED SON replacement lamps is set to shake the retrofit SON market, reaching a staggering 140 lumens per watt (Lm/W).



Traditionally, SON-style LED lamps have been specified to replace E27 and E40 lamps usually associated with industrial lighting applications in high and low bay lighting, or for exterior use in bollards and street lighting. However, these LED lamps generate high temperatures during operation which can result in premature lamp failure. To combat this problem, manufacturers have to incorporate bulky heat sinks and cooling fans into the design of the lamps. This is not an ideal solution because, apart from the unsightly appearance of the heat sinks, the motor-based fans also generate high noise levels which can be unacceptable even when lamps are installed at heights up to 10 metres.

Frequently, the problem of noisy fans in traditional SON-style LED lamps has been exacerbated by the high failure rates of the fans themselves. A reliance on moving parts, such as sleeve and contact bearings, means that excessive wear often results in unstable fans, poor performance and, ultimately, failure. To eliminate this problem, the Goodlight G360 LED SON replacement lamps incorporate patented MagLev (magnetic levitation) fan technology which eliminates the need for bearings. As a result, the new fans generate less than 0.5dB, making them almost silent in operation.

Another unique feature of the new Goodlight G360 LED SON replacement lamp range is the dual function of its integral heat sink. The innovative aluminium heat sink has been designed as a skeletal frame onto which the light-emitting PCBs are securely clipped. This revolutionary design obviates the need for solder or screws so problems associated with dry joints and vibration do not arise.

The incorporation of MagLev fan technology, matched to an ingenious heat sink, ensures that the new range of Goodlight G360 LED SON replacement lamps provides a unique thermal management system. This means that the lamps utilise higher powered LED chips – achieving 140 lumens per watt - to operate ultra reliably at temperatures above 70°C thereby achieving unparalleled brightness across a wide range of industrial, commercial and street lighting applications.

“Our new range of Goodlight G360 LED SON replacement lamps is the result of several years of meticulous product development and exhaustive testing,” says Saima Shafi, LED Eco Lights’ Co-Founder. “LED SON replacement lamps are very popular due to the energy savings they deliver and the ease of retrofit replaceability. Our new G360 range provides unrivalled lighting levels and reliability with its unique cooling system. Breaking new ground with MagLev fan technology and LED, we believe that our new range is the brightest and most efficient available. Virtually silent in operation, it leaves competitor products in the dark!”

Cree invests in Lextar, plans to source mid-power LEDs from Taiwan manufacturer



Cree ( NAASDAQ: CREE ) and Lextar ( TAIEX: 3698 ) have announced a business relationship in which Cree will invest in the Taiwan-based LED manufacturer and will source LEDs from Lextar for use in future solid-state lighting (SSL) products. Cree will purchase 83 million Lextar shares and will assume 13% ownership in the company while Lextar will get access to Cree intellectual property and to Cree Lighting as a customer for its LEDs.

While the summer has been relatively quiet in terms of new LED product announcements, the business side of the sector has been quite busy. In July we saw Epistar acquire Formosa Epitaxy (Forepi) despite the fact that Epistar rival Sanan Optoelectronics owned a large share of Forepi. That acquisition apparently was driven by Epistar's need to ramp capacity amid growing demand for LEDs from the general lighting sector.

The Cree and Lextar agreement could be driven both by capacity concerns at Cree and by the fact that Cree has not invested heavily in traditional mid-power LED product lines. Cree has announced a number of very-small LEDs such as the XLamp XB-H that came to market in March, but the devices exhibit high-power performance and are packaged in high-reliability yet expensive ceramic.

While Cree has insisted that ceramic-packaged LEDs are the best fit for lighting, there are clearly applications such as linear fixtures that are a good match for mid-power LEDs in either plastic or hybrid packages that bring some of the reliability benefits of ceramic. With Cree expanding its presence in the end lighting market, the need for a mid-power source for some products is an expected development.

"We are excited to be strengthening our relationship with Lextar to enable growth in LEDs and lighting," stated Chuck Swoboda, Cree chairman and CEO. "Working with Lextar to supply high-quality, mid-power LED chips enables Cree to focus its resources on the high-performance, high-power LED chips that differentiate Cree LEDs in the market. This approach provides the operational and financial flexibility to help Cree achieve the best return on our people and invested capital."

For Lextar the benefits of the relationship are perfectly clear. The company gets capital that can help it expand production. And the Cree intellectual property cross-license will prove important to the company serving lighting customers other than Cree.

"Lextar has established a strong technology position and customer base in the mid-power backlighting LED segment, while Cree has had outstanding performance in the high-power LED component and lighting markets," said Dr. David Su, chairman and CEO of Lextar. "We are very excited about this new cooperation with Cree. We strongly believe this new collaboration will increase the competitiveness of our products and technology, enabling both companies continued growth in the LED lighting market. Furthermore, the cross license of LED chip and component intellectual property will afford both Cree and Lextar the benefits from our product and technology development, thereby strengthening our mutual competitiveness in the global LED industry."

Lextar and Cree both just announced quarterly financial results and once again Cree's revenue was up significantly. Lextar also announced an 18% increase in revenue and said it had overcome manufacturing roadblocks that had gated growth and the company pledged to expand capacity.

Cree's investment will help enable the Lextar goal of expansion. Cree will pay NTD 30 ($1) per share for the 13% stake, equating to an $83 million investment. The companies said that both boards have approved the deal and it is expected to close by the end of the year.
