The illumination and xbox 360 led strip are currently in the two biggest application, and led the constant advancement of drive modern technology is the two huge application to the popularity of the power. "In recent years, LED drove by linear dropout regulatory authority (LDO). Quasi reduced charge pump type to switch over, a shift in efficiency, current drivers, capacity had substantial development. The efficiency is also considerably improve the development of semiconductor modern technology. With, particularly high voltage and BCD modern technology unceasing enhancement, some peripheral power switch tube and diode are also integrated into the drive chip, make peripheral circuit considerably streamlined." Maxim sang Technology Co., LTD

. Led downlights 12v with LED the chip advance, make the power LED more and more huge, the brightness of more and more high, its application is becoming more and more widely. From early instrument instructions into LCD screen back illumination, flashlight, car program, illumination, attractive light and so on, until basic illumination applications, such as the berth light, table light, ...
... fluorescent light and light, etc

. "In recent years in the process and design development in the ascension of the item operation also increased a led the variety." Set modern technology YingXiaoChu, deputy director of ChenJunCong said. "Such as minimizing outside parts correspondingly reduce the blank application and item volume. Process modern technology promotion make items can easily load more current and voltage, and support more LED parts. These applications are in LED support. And because of the dimension, can be applied to lower LED in the mobile flash on the increasing... The luminous efficiency as the projector that the LED light source, these impressive application hair is the procedure and design with the development of the supplement each other."

In recent years, LED the development of the drive modern technology mainly in the exceptional efficiency, high power, high pressure modern technology. In the cell phone portable field, the major is a white LED drive application, now of the reduced voltage distinction drive, charge pump type drivers are to the application and development drive method, reduced voltage distinction driver can easily put the pressure distinction do really reduced (50 mV / 20 mA), charge pump type to drive is now 2 times, 1.5 times and 1.33 times, etc, the objective is to improve efficiency, increase the voltage application variety. The business currently has introduced impressive business and driver were first Yin and Yang of reduced voltage distinction of LED drive chip, will certainly soon introduce and drive of Yin and Yang LED the charge pump sort of drive chip, allegedly the chip can just make use of an external capacitor 1 X 2 X to recognize automated adjustment of the voltage between, therefore considerably improve the efficiency of the LED.

"LED modern technology is also fast development, now LED the luminous efficiency has enhanced enormously, turn-on voltage also do more reduced, so now the high brightness LED made use of more and more widely, but the major or back illumination and the advancement of the illumination applications."

"In the illumination applications, for, efficiency is the major key issue. Since the wattage and outcome current bid and produce the issue of high temperature is needed to improve the spot, but also the item promotion points."

"At present, the LED drive is the most significant complications encountering the heat consumption and its associated stability complications. This will certainly need to drive the chip further reduce power consumption, lower their itself fever. At the same time, since applied to big contemporary high power functions, drive chip voltage overshoot, ground pulsation and electrostatic protection is needed to work with the great, so as to improve the system stability. In addition, drive modern technology how to address and now the power of the ac drives seamless link, so as to reduce the resistance of the conversion to the LED illumination and cost pressure, is also a challenge."

Led downlights dimmable with the performance and efficiency regularly surpasses traditional illumination modern technology. This brand-new modern technology is substantially made use of. Nonetheless, if we merely make use of the static white CAUSED change the outdated modern technology of words, it will certainly be difficult to play solid-state illumination modern technology full capacity, not completely recognized and the quality of LED illumination items. In intelligent drive support, such as the intro of wireless control, automated light detection and microprocessor modern technology, LED illumination lights and lanterns can easily not just change the traditional white light illumination, and still can easily accomplish brand-new operations, and the operation with traditional illumination modern technology is difficult to accomplish.
