High brightness LED unlimited potential, energy saving and long life is the key factor

In driving around the government vigorously promote energy conservation and environmental protection, high brightness LED began to enter the general lighting market, is widely used in traffic lights, landscape lighting, traffic lights, car lights, interior decoration lamp and lantern etc.. Forecast report of American market research firm Frost & Sullivan show that in 2008 the global LED market will grow to $5 billion 600 million, in the foundation to further reduce the cost and improve the technology, high brightness LED market will grow significantly.

In the LED market, the first breakthrough in high brightness LED technology is Lumileds, about 2002. In the next three years, Lumileds in this field is almost dominated by its introduction of a variety of packaging forms and installation accessories, almost become the industry standard. However, since 2005, Lumileds market began to change, especially in the last two years, CREE and Nichia and other manufacturers continue to introduce high efficiency and high brightness LED products, Lumileds broke a monopoly market structure.

Cree was founded in 1987, in 1989 developed the world's first Blu ray LED, is a company with a long history in the field of LED. But in the high brightness LED market, Cree is an up and coming, until February 2006, it launched the first high brightness LED products, however, Cree in the LED brightness and efficiency of the rapid reform of its competitive advantage. "Our sales in 2006 amounted to $423 million. "Cree's global Peter channel manager Walker said that in March this year, Cree in Huizhou with a $200 million cash acquisition of privately held LED suppliers in Hongkong Cotco (Hua Gang) lighting equipment Co. Ltd., which not only in the field of chip sales ranked first, and entered into the fast growth of the Chinese solid-state lighting market.

Market drivers: energy saving and long life

To replace the traditional light source, LED must be able to provide both high brightness and high efficiency. Therefore, for actively engaged in the field of high brightness LED semiconductor manufacturers, the key to achieve market leadership is the product brightness and efficiency of technical breakthroughs. Following the March production of 80 lumens / watt products, Cree is committed to continue to provide the existing XR-E series brightness and efficiency. "We in September this year, the successful development of higher efficiency of cool white and warm white LED products, including LED products, cool white light efficiency reach 129 LM / W, warm white products reached 99 LM / W. This further reinforces Cree's leading position in the field of solid-state lighting. "Walker representation.

Walker in the recent Cree and Ai Rui electronics held in the LED seminar in Shenzhen to share the technical blueprint for Cree lighting in LED. He said that the recent Cree will focus on improving the XR-E and XR-C series of product brightness and efficiency, is currently developing 140 lumens / watt products, and is scheduled to launch in the first half color XR-E series of products, in order to broaden the scope of application of high brightness LED in the lighting field, in applications such as street lights, tunnel lights and traffic lights etc.. Walker believes that with the further breakthrough in brightness and efficiency, 2008~2009 will usher in the outbreak of the high brightness LED market.

Energy saving is one of the most prominent advantages of LED, but also one of the driving forces to promote the high brightness LED into the field of lighting. For the superiority of the interpretation of LED in terms of energy saving, AECO electronic lighting products business development director Wu Bingyan at the seminar were compared with the brightness of the lamp and LED lamp, such as a 90 lumens / watt lamp and 90 lumens / watt LED lamp, the brightness of the two indicators, consistent. But in fact, due to the different efficiency of the use of the two, they are reflected in the final brightness is not the same. The lamp light source is very fragmented, the light utilization rate of about 45~50%, and the light source orientation of LED is very good, the use efficiency of about 90% can be achieved, even more, it is in use, the LED will be a lot brighter than the lamp. He pointed out that in the field of high power LED, not just to see the product lumen / watt values, but also to see the use of (Usable) lumen indicators, the use of different efficiency, the actual embodiment of the brightness of a far cry. "

Super long life is another key factor driving the LED market to take off. At present, Cree launched a high brightness LED products use time more than 100 thousand hours, if you take into account the life of the drive parts and other accessories, the use of the entire product will be more than 50 thousand hours. Wu Bingyan said that the characteristics of the ultra long life on the one hand saves the user maintenance costs and time, but also reduces the waste bulbs and packaging materials, which is more conducive to environmental protection.

Walker also pointed out that now is the best time to open the high brightness LED business functions, mainly from three aspects: on the one hand, LED technology has made new breakthroughs in brightness; on the other hand, LED has the advantages of energy saving and long life, can greatly reduce the maintenance cost of the user; three is the local government is actively promoting environmental protection the policy will further promote the wide application of LED. "In some developed countries in Europe and the United States is thinking about these issues, and the introduction of various policies, such as the provisions of Austria after 2010 does not allow non LED lights to enter, and some provisions must be used to achieve 45 lumens / watt lamps above, more efficient. Driven by government policies, the market for high brightness LED lighting applications. "

Constraints: heat and cost issues

Despite the promising market, but the relatively high cost of heat dissipation is still hampered by the rapid growth of high brightness LED market constraints. LED has made great progress in the brightness, but most of the LED power is transformed into heat conduction. In addition, for general lighting, several LED will be required to place the
