LED technology patents open future road will be unimpeded

LED lighting will become mainstream in the development of lighting technology has become a consensus, the traditional indicator for display, and the small screen LCD backlight application will be limited, with lower costs, power and efficiency, has become the mainstream product in the backlight automotive electronics, home lighting, large screen flat-panel display and lighting applications in higher power. In this international IC exhibition, we saw a variety of leading LED drivers, including the international leading semiconductor companies such as Freescale Carle, Zetex and many local IC companies. The Huarun silicon micro semiconductor company exhibited its independent development of LED drivers, boost buck converter series circuit, the company will LED lighting chip solution as one of the main direction of the company's product development, future plans to develop a full range of LED drive solutions.

In the past few years, LED technology has made great progress, in the heat dissipation, packaging and process technology advances make LED has a higher brightness, higher efficiency, longer life and lower cost. In the current global environmental protection, energy saving technology research and development, no doubt LED lighting energy saving, high efficiency advantages will get the favor of the lighting market. "We are very optimistic about the prospects of the LED lighting market, has been LED driver solutions as one of our product development direction. At present, we have launched the 5W LED program, the next step will be launched 10W and 75W chip program, the formation of a comprehensive series of product lines. Silicon micro technology general manager Ling Hui said. At present, the company's LED products include a series of backlight drive, parallel LED drive charge pump, but also provides no need for capacitors, inductors, LED driver.

High power white LED patent is currently mainly in the hands of Japanese companies, most patents will expire this year, so the future of white LED will be cheaper, the overall market capacity will grow rapidly. "Ling Hui optimistically pointed out. Compared with incandescent lamp, LED lighting solution has the characteristics of long life, high reliability and high energy conversion efficiency. The adoption of a large number of LED will certainly promote the growth of demand for LED drives IC.

However, in terms of energy conversion efficiency, heat management and production costs, LED still has room for further improvement. LED to be more widely used in lighting applications, has yet to be LED material and semiconductor driver solution technology progress and cost reduction, cost-effective solutions like silicon micro technology these local IC company innovation will accelerate the popularization and application of LED lighting, LED material is an important factor to enhance the performance and cost of itself the drop is LED lighting market development, white LED material patent will enable LED lighting the early arrival of spring.
