savings due to decreased maintenance and lower energy consumption compared to the linear fluorescents we replaced.”
The CS Series is designed for low maintenance and long life – lasting up to three to four times longer than standard fluorescents and enhancing the appearance of any space. The new luminaire introduces a deceptively simple yet highly efficient optical design approach that integrates an upward- facing LED light strip with Cree TrueWhite Technology and an ultra-lightweight upper reflector, featuring all-new Cree MicroMixing Optics for precise optic control. The CS Series comes standard with 0-10V dimming control to five percent and features a seven year warranty.
“Everything we do at Cree is focused on accelerating LED acceptance and the latest CS Series innovation delivers on our promise and truly provides a no-compromise alternative to fluorescent lighting,” Elien continues. “Businesses no longer have to choose between colour quality and savings and no longer have to suffer the poor performance, toxic mercury and hazardous disposal expense inherent with fluorescent lighting. The colour quality and visual impact offered by Cree CS Series makes it the ideal solution for large retailers and industrial users.”
New, innovative Cree MicroMixing Optics are formed from thousands of tiny impressions imprinted on the state-of-the- art highly reflective polymer material. Unlike direct-view LED solutions, this multi-faceted pattern blends and softens the intense light and redirects it with precise control and colour mixing. The result is beautifully balanced white light with optimal distribution within the desired area.
The Cree CS Series LED Linear Luminaires are made in the United States and sold through Cree lighting sales channels with sample quantities targeted for availability in May 2012
Carsem focusing on LED manufacturing
he firm has successfully assembled and qualified high brightness silicon substrate LED arrays and will begin offering high-volume, full turn-key manufacturing services. These include electrical testing, laser mark and tape-and-reel production
Carsem is now entering a partnership with a key customer to assemble and further develop LED packaging technologies.
The manufacturing process fully utilises the advantage of standard mass production process of assembly and test including matrix substrate design; auto die attach, wire bond and high reflection coating dispense; compression moulding through automould system; mapping of units on substrate and bin sort per test mapping.
This silicon substrate LED array offers higher white light brightness with much less energy required (over 50 lumens/ watt). The life expectancy of the product is estimated to be 10 years. General applications can be home use, cars and special lighting effects.
Albert Law, Carsem’s V.P. of World Wide Sales and Marketing says, “Because of our extensive experience in providing turnkey solutions, we are able to share our expertise with our LED customers and assist them in getting their products to market faster with turnkey solution on high density and high volume packaging, Carsem is expanding the company’s portfolio to include LED packaging solutions for the high brightness LED applications.”
Carsem’s Chief Technology Officer, L.W. Yong adds, “By capitalising on our extensive semiconductor experience in materials, process & equipment we have successfully advanced into the LED arena and thereby enhancing the manufacturability and efficiency of high brightness LED.”
Hangzhou Silan Azure impressed with Veeco MOCVD systems
The firm has placed a multi-tool order to expand Silan’s manufacturing capacity for blue and green nitride based high brightness LEDs
Hangzhou Silan Azure Co. Ltd., an LED manufacturer in China, has placed a multi-tool order for Veeco’s TurboDisc K465i MOCVD systems.
Zhongyong Jiang, President of Silan Azure, comments, “The growth we are experiencing supplying LEDs for general illumination, backlighting and outdoor display applications required us to add manufacturing capacity at our Hangzhou facility. After evaluating various suppliers, we chose to purchase additional systems from Veeco because of our satisfaction with the production-worthiness and reliability of existing K465i MOCVD tools at our fab. The excellent field support we have received from Veeco was also a major factor in our decision.”
William Miller, Executive Vice President of Veeco Process Equipment adds, “We are pleased Silan Azure has chosen the K465i for their manufacturing expansion, and look forward to continuing to build upon our relationship with one of China’s top LED manufacturers.”
Is Cree the best in LED
luminaire test? Maybe so. The Cree Technology Centre has achieved NVLAP accreditation with its comprehensive test for LED testing parameters for system design and quality Cree is adding “TEMPO 24” to its comprehensive suite of Cree Services for LED luminaires.
The new TEMPO (Thermal Electrical Mechanical Photometric Optical) 24 service combines IES LM-79-08 photometric testing with an extensive set of LED performance tests that it says, surpasses all industry testing parameters and can help ensure total system design and quality.
