The Cree Durham Technology Centre has been accredited by The National Voluntary Laboratory Accreditation Program (NVLAP) and furthers Cree’s commitment to helping LED manufacturers overcome design challenges and bring quality products to market faster.
“LM-79 is a necessary test and has become a requirement for doing business in the Solid State Lighting market,” says Mark McClear, director of global applications engineering, Cree. “TEMPO 24 includes a fully accredited LM-79 test, but goes well beyond this or any currently existing standards. Cree has identified through our years of SSL experience nearly a dozen other potential problem sources of LED luminaire design. Our goal is the same as our customers - and their customers as well --quality SSL products that save energy. TEMPO 24 helps ensure this and gives customers the information they need to design and specify an SSL product with confidence.”
“In my experience, if I had to select a single document that’s had the greatest impact in selling LED light sources to customers, it would be the Cree TEMPO report,” adds Pierre van Helden, CEO, LED Lighting SA. “The service provided an independent and thorough review for our products and the results give us the confidence to sell our products with passion--giving our customers the assurance that our products are being designed and produced to the highest international standards.”
TEMPO 24 provides LED luminaire tests that are not offered by any other third-party testing facility. In addition to LM-79 testing which is an approved method for taking electrical and photometric measurements, TEMPO 24 testing includes binning and color point evaluation, chemical compatibility and TM-21 lifetime projection. TEMPO 24 examines all aspects of an LED design and provides customers a true assessment of luminaire performance that can be used to promote and distinguish their product. Every TEMPO service delivers an accurate, easy-to-understand TEMPO report that includes all testing results and relevant performance data.
Cree’s Durham Technology Centre NVLAP accreditation (NVLAP lab code 500070-0) ensures that TEMPO measurements are performed according to the Illuminating Engineering Society (IES) approved method for the electrical and photometric measurements of LED lighting - delivering lighting manufacturers consistent, accurate and repeatable measurements for luminaires.
NVLAP accreditation signifies that a laboratory has demonstrated it operates in accordance with NVLAP management and technical requirements pertaining to quality systems, personnel, accommodation and environment, test and calibration methods, equipment, measurement tractability, sampling, handling of tests and calibration items, and test and calibration reports. Cree laboratories also work to American National Standards Institute (ANSI) and National Institute of Standards and Technology (NIST) requirements.
Cree currently provides TEMPO Services out of its Cree Technology Centre located in Durham, N.C. and Santa Barbara, California.
SDK and Toyoda Gosei JV to
accelerate GaN LED business While the JV will focus on gallium nitride LEDs, SDK will concentrate on the production of LED chips made from other materials such as aluminium indium gallium phosphide and gallium arsenide
Japanese firm, Showa Denko K.K. (SDK) is splitting its business in GaN-based blue LED chips to form a new joint venture with Toyoda Gosei.
SDK will transfer 70% of shares in the new company, tentatively be called TS Opto Co., Ltd., to Toyoda Gosei by the end of this year.
The JV will focus on the production and sale of GaN-based LED products and will be established at SDK’s plant in Yawata Kaigan Dori, Ichihara City, Chiba Prefecture.
SDK is already cooperating with Toyoda Gosei, a developer and marketing of GaN LEDs. By establishing a joint venture with Toyoda Gosei for the GaN LED business, SDK will further strengthen relations between the two companies and expand overall supply capacity. At the same time, research and development at SDK will focus on improving LED brightness and production efficiency.
In the LED business other than in GaN LED chips, SDK will continue its independent operations. The firm is currently producing and selling a wide variety of LED chips, including those based on AlInGaP, GaAs, GaP and GaN.
The new company is scheduled to be established in December 2012 and the intended capital at the time of the formation is planned to be Y490 million (USD $6.05 million). Seventy percent of the JV is to be owned by Toyoda Gosei and the remaining 30 percent by SDK.
Lumileds` new LUXEON R is appealing for outdoor lighting
The new LED lowers outdoor lighting system costs and improves efficacy Philips Lumileds has launched a new LED designed for outdoor and industrial lighting applications such as streetlights, high-bay lights, wall packs and bollards. LUXEON R is an Illumination Grade LED, and therefore is Hot Tested and Specified at Tj=85°C so that its performance at operating conditions is well understood. The new module offers Freedom From Binning to ensure uniformity from solution to solution. LUXEON R is also footprint compatible with LUXEON Rebel and LUXEON Rebel ES, while delivering more light output, higher efficacy and better quality of light.
