National semiconductor high brightness, low power LED to drive the world with high efficiency

National Semiconductor Corporation Ns (National Semiconductor Corporation) in Guangdong held the seventh session of the Zhongshan municipal Chinese Guzhen International Lighting Fair (Guzhen Fair) wonderful presents "high brightness, low power LED series solution. LED technology in the distinguished reputation for the first time to participate in Guzhen lights Fair of the U.S. National Semiconductor during the exhibition attracted much attention. The solution of the latest PowerWise, LED lighting system involves a number of application fields of indoor and outdoor lighting systems and automobile lighting systems, has attracted many visitors in a continuous line, veteran domestic and foreign well-known manufacturers of LED lamps.

As a leader in power management products market, the United States National Semiconductor for many years has been committed to "the world's energy saving" goal, and continue to develop a variety of energy efficient LED solutions. PowerWise LED lighting system solution the lamp will be unveiled in the town of Bo has very high power / performance ratio, the optimization of the LED drive not only high efficiency, complete function, can also reduce the number of external components. In the booth, visitors to the widely used MR16 high brightness LED lamp and LED lamp very interested, in cooperation with the national semiconductor drive efficiency as high as 96% under the MR16LED lamp and LED lamp efficiency can be further improved. Based on a deep understanding of market demand, the U.S. National semi conductive LED series solutions also provide accurate current control, dimming control, thermal management, and many other features, and compact size, easy to use.

In the attention of indoor and outdoor lighting applications, national semiconductor has shown a series of input voltage range of LED drive operation in the wide, and is very flexible and easy to use, to attract a lot of visitors. High brightness also means the need for more complete thermal management, otherwise it will shorten the service life of LED. In the automotive lighting system design and display backlight scheme, can display the national semiconductor solutions appeared in the current system, overvoltage or high temperature conditions, a fault alarm, to ensure that the system is stable and reliable, the automobile lighting system is an ideal solution.

In addition, the United States National Semiconductor also provides heating management chip, can be used with the LED driver. These thermal management chip series can be applied to street lights, projectors, cars and other lighting design, so that the LED lamp more stable operation, while extending the service life of LED.

During the fair, the United States National Semiconductor high performance power product line marketing director John Nettle and senior manager of the Asia Pacific region, Wu Zhimin also visited the scene with the Chinese designers conducted in-depth communication.
