ON Semiconductor (ON Semiconductor) LED general lighting and power marketing and system engineering director Laurent Jenck told correspondents, LED is the fastest growing semiconductor market, with annual compound growth rate of 19.3%. This is a key driver of LED energy saving, long life, excellent color combination and the environment. For example, less than 4 inches in screen size of mobile phones, cameras flash and other mobile devices, applications, and roadside and sports a large screen in the application, LED lighting, or solid-state lighting (SSL), account for almost 100% of the share . In addition, LED lighting is also moving to other areas, such as in automotive applications, LED lighting account for about 15% of the share. In a large liquid crystal display (LCD) backlight applications, although the cold cathode fluorescent lamp (CCFL) is still dominant today, but the total penetration rate of LED lighting has reached about 20%, especially in the high-profile large-size LCD TV backlight applications, according to Laurent Jenck said it expects LED-backlit LCD TV in the next three years to four years, will account for 50% of the share.

In comparison, LED lighting bulbs, recessed lighting, street and area lighting, lamps, landscape lighting, commercial buildings, lighting and billboard lighting, general lighting circuit text field penetration ratio is still low, currently less than 2%, much lower than other lighting types. Laurent Jenck said that the main reason is the cost of LED is still relatively high, the price is the field of LED lighting in general lighting the rapid spread of a constraint. Laurent Jenck pointed out that the energy-efficient LED lighting has advantages, such as applications and application Extension of the increase, LED lighting, the price / cost will gradually tend to consumer applications. Expected, LED general lighting is expected to begin within five years into the mainstream home use.

For different LED lighting, should select the appropriate driver program. Laurent Jenck said, ON Semiconductor offers a wide range of energy-efficient and innovative and robust program of LED lighting drivers. Wide range of applications and is suitable for any power range, for example, from convenience to the car battery-powered interior lighting, to the general lighting, building solid-state lighting, whether products directly powered by AC or DC circuit application, and so on. ON Semiconductor provides a suitable energy-efficient LED driver solutions are, inductive, and charge pump based LED drivers, switching regulators, integrated circuits highly integrated lighting management (LMIC), a linear constant current driver (CCR), power factor Correction (PFC) integrated circuit, high voltage switching power supply program, and a wealth of MOSFET, rectifiers and other discrete circuit protection products and series. Laurent Jenck said ON Semiconductor also has energy efficient power supplies and packaging of core technology, simulation and dimming technology, flyback converters and non-isolated DC - DC topology and some other unique LED drive power structure. Solutions include standard products, special programs, application specific standard products and full-custom ASIC solutions. Next, the Semiconductor segment will also meet different application requirements and the power level of current demand, and provide energy-efficient tested GreenPoint reference design to help designers to reduce design cycles and accelerate time to market.
