In recent years, the LED lighting industry has benefited from the continuous promotion of policies and the maturity of technology, coupled with the reduction of costs, and its application fields have gradually penetrated into various channels. The LED lighting market is becoming a major competition for major manufacturers. Marvell, a leading semiconductor company in the industry, is very optimistic about the prospects of the LED lighting market, and in recent years it has also actively worked in the field of LED drivers. Marvell's firm confidence stems from the following three aspects. First, they firmly believe that the huge market of LED lighting has just started; second, they have brought breakthrough deep dimming technology; third, they are innate in smart lighting and smart dimming Technical advantages. Mr. Guan Zhenyuan, Marvell ’s technical marketing manager, said that although Marvell is a new face in the field of LED driving, it has many years of experience in power supply driving technology and product distribution; Marvell has the most cutting-edge mature digital-analog hybrid technology in the industry, which can help LED lighting The industry realizes the optimization of performance price. Figure 1: Marvell Technical Marketing Manager Mr. Guan Zhenyuan Mr. Guan Zhenyuan revealed that as early as early 2011, Marvell launched the industry's first intelligent independent dual-channel DC / DC driver chip-88EM8801; in early 2012, Marvell released a new generation of thyristor dimming AC / DC driver chip-88EM8183 The chip is a high-performance low-system-cost chip, which can reduce system cost by as much as 30% to 40% compared with industry competitors, increase efficiency by 3% (based on 10W), and non-isolated efficiency up to 90%. As a latecomer to the market, this product is used as a platform by many well-known ODM / OEM manufacturers around the world, including Ikea, Samsung, Cree, Bestbuy, Osram, etc. ODM / OEM manufacturers can produce high performance by using 88EM8183 driver IC , Low-cost LED bulb, and compatible with most SCR dimmers in the industry. The highly integrated 88EM8183LED driver IC can make the dimming curve perfectly close to the dimming effect of traditional incandescent lamps, and achieve a high degree of dimmer compatibility. Compared with industry products, it has significant performance advantages. Single-stage primary current control, PFC and valley detection, integrated high-voltage MOS startup and low-voltage MOS auxiliary dimming circuit; 88EM8183 has obvious advantages, has excellent dimming performance, high PFC and low THD, and can greatly reduce the bill of materials and reduce costs , Extend the life of the entire LED bulb. And it is also very advantageous in dimming compatibility. 88EM8183 is compatible with most thyristor dimmers, including front-cut, back-cut dimmers and digital dimmers. Figure 2: LED lighting products using Marvell LED drivers Mr. Guan Zhenyuan, Marvell's technical market manager, said that vigorously promoting LED lighting is not only an inevitable demand for energy saving and emission reduction, but also an important measure for building a sustainable development society. LED efficient lighting solutions are an important boost to promote the popularity of LED lighting. As the world's leading provider of integrated chip solutions for storage, communications and consumer electronics, Marvell can provide a wider range of comprehensive, high-performance, low-power products, as well as digital PFC for multiple high-speed consumer and enterprise markets Controller power management products. For a long time, Marvell has unswervingly developed green technologies in response to the call for energy saving and carbon reduction. Marvell owns the cutting-edge power management technology of digital power factor correction (PFC) controller. "It is precisely because we are very optimistic about the market prospects of LED lighting, and we have an unusually rich accumulation of high-end technology in LED drivers with high energy efficiency and deep dimming technology, which prompted us to get involved in the field of LED drivers and commit ourselves to fully exploit the LED lighting. Potential. Marvell ’s high-efficiency LED lighting solutions have unparalleled strengths in terms of cost reduction, performance improvement, deep dimming and dimming compatibility. " The future of LED lighting-intelligent With the continuous maturity of LED lighting technology in the future, LED lighting products will not only improve in luminous efficiency, reduce energy consumption, but also reduce the cost of LED chips and packaging costs. , To promote the further popularization of LED lighting. In what direction will LED lighting develop in the future? Mr. Guan Zhenyuan, Marvell's technical marketing manager, said that LED lighting is bound to become intelligent. What is intelligence? Mr. Guan Zhenyuan, Marvell's technical market manager, said that traditional optical and acoustic sensor control has achieved simple and intelligent early stage, and intelligent lighting based on the Internet of Things is the future trend. Relying on a strong communication technology background, Marvell proposed a full set of open solutions, including a mature software platform, a low-cost and high-performance Wi-Fi / ZigBee gateway solution, a light control turnkey solution, and a cloud service integration solution. Figure 3. Marvell intelligent lighting platform based on ZigBee From the perspective of future market development, Marvell has a comprehensive solution, has more market contact points with customers, and it is easy to form a deep customer relationship. Marvell's smart lighting related solutions highlight its differentiated advantages compared to other manufacturers. What is differentiated advantage? Although Marvell is not as famous as the end consumer manufacturers, it has extraordinary strength and unique status. Marvell is the top five fabless semiconductor companies in the world: it sells 1 billion chips every year in storage, network, mobile Leading the market for multiple chips in wireless, consumer electronics, and green energy, with a 70% market share in the hard disk controller market. Acquired the Intel Wireless Division in 2006, which has a great advantage in the smartphone chip market and in the field of wireless communications It has accumulated abundant technical capital and market advantages. After Marvell entered the LED driver market, facing the needs of intelligence, Marvell took advantage of deep technical advantages to actively improve smart lighting solutions. In the wave of LED industry reform, it adhered to the concept of changing the world with technology and welcomed mobile Internet, cloud computing, and Internet of Things. New era. The differentiated advantage of Marvell is that Marvell has comprehensive solutions such as optical fiber communication, mobile cellular communication, Ethernet / Wi-Fi, power line communication, Bluetooth / ZigBee / NFC, and has formed interconnected solutions at all levels. Focusing on a comprehensive connected life solution, Marvell pays more attention to the linkage and overall consideration of products in the development of technology and products, which benefits customers.
