The LED industry is still a blue ocean market one minute earlier, and in the blink of an eye there is a red sea. Major manufacturers are rushing forward, causing chaos and disorder in the entire industry, and various products are uneven. With the decline of LED prices, its application in the commercial field is more and more. With the support of national policies, it is believed that LED will show rapid growth in the next two or three years. As a rising star in this industry, how can Marvell use its own technological advantages to kill a blood in this fiercely competitive market?
The development demand of the commercial LED lighting market drives the intelligent dimming market of LED lamps
With the continuous improvement of LED light source technology, the price of terminal lamps has shown a rapid downward trend. Taking LED bulbs that can replace 60W incandescent lamps as an example, the retail price in 2010 was $ 40, but this year the price has dropped to $ 10. With the strengthening of the popularity of LED lighting by the Chinese government, it is expected that the global LED lighting market will gradually pick up in 2013, and the price will enter a new round of downward adjustments. about.
According to the "Twelfth Five-Year Special Plan for the Development of Semiconductor Lighting Technology" promulgated by the state, by 2015, the scale of China's LED lighting industry will reach 500 billion yuan. 50 "ten cities and ten thousand lamps" pilot demonstration cities promote China's semiconductor lighting industry to enter the world's top three. The “Twelfth Five-Year Plan†of the National Basic Public Service System also mentioned that 2.2 billion yuan of financial expenditure will be arranged to support the promotion of energy-saving lamps and LED lamps. Industry insiders said that the 2.2 billion subsidies will reduce the price of LED lights by 15% to 20%, which will stimulate the nationwide acceleration of the promotion and application of LED lighting products, especially the civilian and commercial LED lighting markets.
In recent years, with the rise of the global LED commercial lighting market, many LED manufacturers, including China, have placed LED commercial lighting products in an important position in market development. In particular, due to the recent high-efficiency, long-life, high power factor, flexible expansion, and dimmable requirements for LED lighting products in major markets such as Japan, Europe, and the United States, the LED driver IC and power supply industry is facing a new change . Therefore, in the next two years, the proportion of smart dimming of LED lamps, especially in commercial lighting, is expected to increase rapidly.
Solving the problem of dimming compatibility is the key to the current development of the LED lamp market
LED bulbs have excellent energy efficiency and long life, and are considered as a substitute for incandescent lamps and compact fluorescent lamps. Research firm Datapoint Research estimates that the LED lighting market in lighting applications will grow from approximately 200 million in 2011 to 1 billion in 2015. But at present, the main obstacles affecting large-scale adoption come from relatively expensive procurement costs and the same dimming compatibility issues as compact fluorescent lamps.
Marvell Green Technology Product Technology Marketing Director LanceZheng
"In LED lighting applications, the challenges faced by dimming technology are very large." Marvell LanceZheng, director of technical marketing for green technology products, said that the current main challenge is that the price of LED light sources is declining, but there is no great innovation in driving electronics technology The price has remained high and there is pressure on costs. Secondly, because LED lighting mostly adopts the current driving mode, and the existing dimmers are mostly voltage dimming, the challenge in compatibility is also quite large. In addition, the trend toward thinner and lighter power supplies also requires smaller size LED drivers. As a consumer, LED lighting products need to use driver IC dimming technology to provide consumers with a unique sensory experience.
Marvell® 88EM8183 achieves a deep dimming of at least 1%
“Marvell ’s LED solution portfolio uses innovative lighting architecture and network technology to enable outstanding green LED lighting applications. These complete LED lighting solutions are designed to provide cost-effective, fully integrated end-to-end chip and software solutions that allow OEMs can develop best-in-class LED lighting and lighting control solutions. "LanceZheng said of Marvell's LED solutions. Marvell's innovative mixed-signal LED drive architecture provides high efficiency, high power factor, and low harmonics for LED lighting applications, while advanced dimming technology ensures deep dimming and compatibility with existing lighting architectures. In addition, the high integration of integrated circuits (ICs) can reduce the cost of materials, allowing the use of compact printed circuit boards (PCBs).
Marvell®88EM8183
The Marvell solution for the retrofit bulb home market is based on 88EM8183 (deep dimming single-stage AC / DC constant current controller) designed for offline dimmable LED lighting applications. It can achieve a minimum of 1% deep dimming. In comparison, similar LED driver solutions can only achieve 10% to 20% dimming, and are highly compatible with a wide range of thyristor dimmers. 88EM8183 adopts a unique primary-side current control mechanism, which can achieve its strict output current rectification in a wider AC input range. The device uses quasi-resonant control, valley switching method and power factor correction function, which can achieve high efficiency, high power factor, low harmonic distortion and low electromagnetic interference. The IC is compatible with most dimmers on the global market, and provides excellent light output quality, which can increase consumer satisfaction and reduce returns.
It is worth noting that 88EM8183 can significantly reduce the number of external components of dimmable LED drivers. Marvell's system-wide reference design board requires only 33 components in total, compared with more than 70 yuan in popular solutions on the market. Device. In this way, the cost of the overall solution can be reduced by 30-40%. 88EM8183 greatly reduces the required circuit board area, so it can help OEM and ODM to adapt to various shapes of LED lights, such as A19, PAR, BR, GU10 and Candle, and will not damage the dimming performance.
LanceZheng emphasized, "The significant reduction in the number of components has promoted the popularity of LED lighting technology in applications where both cost and space are limited, such as retrofit lamps. Marvell ’s LED driver prices are 20% -40% lower than competitors’ similar products. "
88EM8183 is very suitable for the following LED lighting applications: GU-10, downlights, panel lights, LED modules, etc.
