CREE: Science and technology innovation lead LED change

Scientific and technological innovation to promote industrial development

Scientific and technological innovation is the driving force for the development of the industry. Comrade Xiaoping said, "science and technology are the primary productive forces", today still makes sense, in the current fierce competition, more innovation to ensure quality and improve performance, promote the development of the company and industry.

CREE was founded in 1987, is the United States listed companies (1993, NASDAQ: CREE), the leading global manufacturer of famous LED epitaxy, chip, packaging, LED lighting solutions, compound semiconductor materials, power devices and RF integration in the industry and. CREE as a leader in the LED industry has been deep and always focus on the field of LED. CREE has a broad and deep understanding of the technical aspects of the material from the LED source to the chip, the package, and the system. CREE is the core of the development and innovation. CREE has been committed to innovation in the field of LED products and technology, leading the direction of the market, and to show the development of the industry as a whole can be achieved.

CREE's innovation is reflected in the performance, optimization, acceptance, breadth, etc.: CREE through high-performance LED products to help achieve low system costs and create greater value. The performance is not only reflected in higher efficiency and higher reliability, more reflected in the higher light color consistency and high color index; CREE for the specific application requirements and optimization design of LED scheme, has more value than the standard scheme, and help improve the LM / yuan and reduce the total system cost; CREE provides comprehensive detection reliable to regulate the market and the promotion of high-quality products to the end user, to help build trust and further reflect the value of CREE; supporting industry development, cultivate the market, promote the vertical integration, the establishment of ecological system of the industrial chain, to help every industry have the opportunity to win in the LED transformation, to achieve a win-win situation.

CREE in 1989 launched the first commercial blue LED, and in 2002 launched the first XBright power LED chip. 2004 CREE released the first for high-power XLamp series of products, then the chip luminous efficiency has reached 30 lm/W - 40 lm/W.

CREE first proposed the concept of lighting level LED, focusing on commercial lighting, hotel lighting, road lighting and other general lighting. The definition of lighting level LED devices includes:

High lumen output under rated drive current

High luminous efficiency, such as CCT = 6500K, 100 - 200 lm/W or higher

- fine color, such as following the ANSI C78.377A standard

- Color: high quality high color index, small chromaticity tolerance, high color stability etc.

CREE lighting class LED device performance continues to make breakthroughs in the brightness, light efficiency, light color quality, life, thermal performance, reliability are leading in the global industry. The advantages of LED lighting class is not only high efficiency and high reliability, but also include a true high color index object color and excellent color consistency, so as to create a comfortable lighting environment.

CREE on 2013 02, 2009, announced a high power white LED lab refresh the industry record again, reaching 276 lm/W. According to CREE R & D report shows that the record is measured in the relevant color temperature 4401K, 350 mA and 25 C. This record broke CREE's 254 lm/W research and development achievements made in 2012 of 04, once again demonstrated the CREE to go all out to achieve innovation and promote the popularization of LED lighting efforts.

Scientific and technological innovation, product innovation

CREE 26 years to science and technology innovation, especially in recent years, the introduction of new products.

CREE high-power LED devices, and constantly consolidate the advantages of innovation. CREE continues to lead the industry in terms of product light efficiency, by the end of 2012, CREE high-power LED device production efficiency reached 200 lm/W. CREE color rendering index in the product, through the patented phosphor technology, to achieve the minimum color index 80, 85, 90 optional. CREE products in light color consistency, the patented EasyWhite based technology, enabling customers to specify the color temperature and light output, to help customers get rid of sub file problems, simplified LED system design and Realization of color consistency of excellent.

CREE integrated COB devices suddenly become a new bright spot. CREE designed to simplify the design and reduce the cost of the system, the introduction of a comprehensive package of CXA COB products, set the benchmark for light quality and light efficiency. CXA series products to achieve up to 95 color rendering index, and through a stable and reliable platform system for lighting manufacturers to provide high performance, design flexibility and low system costs. CXA LED series offers a wide range of lumens to choose and achieve very high levels of light efficiency, there is an optimized design of CXA LED series products to meet the needs of lighting applications.

CREE high brightness (HB) LED devices all have high brightness and high light color consistency, wide viewing angle and high reliability, which can make the whole color display screen brightness, color, white balance can reach the ideal effect. CREE outdoor high brightness (HB) LED device, with three in one surface mount structure with waterproof and anti UV properties, increase the degree of protection screen itself, prolong the service life, suitable for landscape lighting, outdoor displays and other applications. CREE indoor high brightness (HB) LED, in the continuous development of high reliability, high brightness and wide viewing angle products at the same time, more inclined to the development of small spacing products.

Scientific and technological innovation, from the four core technologies

The source of CREE's innovation is to work hard
