[Source: Gaogong LED 's " LED Good Products" magazine May issue Reporter / Zhou Jin ] Technology changes the world, the lighting field is facing a new revolution and replacement, in the next few years, LED lights will replace the surviving 60 The incandescent lamp of the year has become the main source of light for the new phase. In this major reform of the lighting world, Fujitsu Semiconductor has brought a different element to this lighting revolution.
Starting in 2010 and officially entering the Chinese LED lighting market in 2011, as a supplier of power management chips and MCU chips, Fujitsu Semiconductor (Shanghai) Co., Ltd. relies on PMIC and MCU-based technology precipitation, with its own process technology. As well as the quality system, it began to supply L ED driver ICs to the Chinese market, as well as providing complete and intelligent, green and comfortable LED lighting solutions for the industry and the market.
Due to its controllability, LEDs have become more and more important in lighting applications. With the vigorous development of LED street lamps and indoor and outdoor lighting markets, LED wireless dimming control technology has made breakthroughs in the development of the recent period. Since the second half of 2012, various dimmable lighting fixtures have been launched in the market. This year, the trend of intelligent dimming will become more popular and expanded.
However, for LED lighting manufacturers, there are still technical bottlenecks in this field due to the imperfect aspects of software and communication design and debugging. So far, smart dimming is mainly only involved in some high-end LED manufacturers, and the main terminal market is still in Europe, America and Japan.
Focus on dimmable fields
"Fujitsu Semiconductor focuses on the dimming market in LEDs, such as thyristor dimming and smart dimming. In general, Fujitsu LED lighting IC features high efficiency, high PF, low THD, support for various dimming methods, and high supply. Dimming performance." Li Dongdong, product manager of Fujitsu Semiconductor (Shanghai) Co., Ltd. told the "Good Product" reporter.
At present, there are only a few ICs for LED lighting Fujitsu. There are only a few models for general lighting, such as MB39C602 and MB39C604 (in research and development) for general lighting, MB39C601, MB39C603 (in development), and MB39C621 and MB39C62X (in planning) for dimming. .
Among them, for the development of MB 3 9 C 6 0 3 and MB39C604, based on several released ICs will continue to improve dimming performance, including thyristor dimming and PWM dimming performance; at the same time, in the overall BOM Costs will be further upgraded and some new features will be added.
Li Dongdong said: "Fujitsu Semiconductor has a complete QA system. Under this system, our IC will undergo a series of tests before sending samples or leaving the factory, so our IC has great quality and yield. Advantages, the corresponding standard development cycle will be 6 months."
SCR dimming solution
In Fujitsu's "Semiconductor LED Lighting Solutions", the reporter learned that Fujitsu's product development route is divided into three steps: "non-dimming lighting", "dimming lighting" and "smart lighting". As Fujitsu's first lighting chip MB39C601 (LED1), the LED1 advantage is not outstanding in terms of characteristics, but the capacitance range of 26W to 25W is relatively wide, and the power factor of this chip of LED1 is relatively high at night. At 0.95%.
