According to market expectation, the next two years will be a crucial period for the LED lighting market. Various companies are also doing some technical reserves and options, in the hope that the market will fully invest. Among them, LED intelligent dimming is expected to grow rapidly in commercial lighting applications.
"In LED lighting applications, the challenges of dimming technology are very large." Lance Zheng, Marvell's director of technology marketing for green technology products, said that the main challenge is that the price of LED light sources is declining, but the driving electronics technology is not very innovative. The price has remained high and there is pressure on costs. Secondly, because LED lighting 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 lighter and lighter power supplies also requires LED drivers to have a smaller size. As consumers, LED lighting products need to use the driver IC dimming technology to provide consumers with a unique sensory experience.
At the same time, the challenges of large-scale application of Marvell LED lighting: 1, the cost is high; 2. The compatibility of existing basic equipment has not been a large-scale solution; 3, the audience consumer demand is varied.

LanceZheng revealed that the company has now developed an innovative mixed-signal LED drive architecture that 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. Sex. In addition, the high integration of integrated circuits (ICs) reduces material costs and allows the use of compact printed circuit boards (PCBs).
In addition, Marvell's 88EM8183 solution, developed for the retrofit bulb home market, supports wide voltage inputs and LED output power ranges from a few watts to 100 watts. The highly integrated 88EM8183 LED driver IC uses Marvell's unique mixed-signal architecture and advanced dimming control technology to smoothly achieve deep dimming down to 1% LED current compared to competing LED driver solutions Realize 10% to 20% dimming. With this range of dimming, the human eye does not feel much change in light intensity, so the 88EM8183 significantly improves performance. This allows lighting OEMs and ODMs to significantly reduce their design efforts and improve product efficiency through the use of a product platform, reducing the number of LED SKUs and simplifying inventory management.
1. Adopt advanced dimming control algorithm, which meets the requirements of the National Electric Manufacturers Association SSL6 (NEMASSL6) dimming standard.
2. Marvell's unique primary-side current control method is used, which requires no optocoupler and related feedback circuitry, while providing very high regulation accuracy over a wide AC input range.
3. Integrated high-voltage start-up circuitry to power on power-up, eliminating the need for external field-effect transistors (FETs) and associated power circuits.
4. Monitor dimmer status and manage dimmer loading to maintain normal operation with internal digital cores and analog circuitry, eliminating the need for an external dimmer bleeder for the existing solution on the market.
5. Through unique design methods, it achieves up to 90% efficiency, power factor higher than 0.95 and total harmonic distortion below 20%, which enables lighting OEMs and original design manufacturers to easily exceed “energy sourcesâ€. Star "" request.
6. Supports flyback and buck-boost topology for isolated and non-isolated LED lamps.
The development of each emerging industry must go through the process of start-up, development, maturity, and recession. The application of LED intelligent dimming in commercial lighting will inevitably require continuous technological innovation. LED indoor lighting can mature and commercial lighting can break. And out.
