LED commercial lighting applications are growing rapidly

According to market expectations, the next two years will be a crucial period for the LED lighting market, and various companies are also making some technical reserves and options, waiting for the market to break out. Among them, LED intelligent dimming is expected to grow rapidly in commercial lighting applications. LED Lighting--LED Street Light In LED lighting applications, dimming technology faces great challenges. The main challenge currently facing is that the price of LED light source is constantly falling, but the driving electronic technology has not been greatly innovated, the price has been high, and the cost is under pressure. Secondly, because LED lighting mostly adopts current driving mode, and the existing dimmers are mostly voltage dimming, the challenges in compatibility are also quite large. In addition, the trend of thin and light power supplies also requires LED drivers to have a smaller size. As consumers, LED lighting products need to provide consumers with a unique sensory experience with the help of driver IC dimming technology. At the same time, the challenges of large-scale application of LED lighting: 1. The cost remains high; 2. The compatibility of the existing infrastructure has not been solved on a large scale; 3. The consumer demand of the audience is diverse. In response to the challenges posed by the above-mentioned markets, as the world's leading solution provider for storage, communication and consumer electronics products, it has industry-leading LED driver chips and terminal lighting solutions, and has been innovating LED driver electronics for a long time. Ru0026D. , the company has developed an innovative mixed-signal LED driver 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. In addition, the high integration of integrated circuits (ICs) can reduce bill-of-material costs, allowing the use of compact printed circuit boards (PCBs). Simplified inventory management 1. Advanced dimming control algorithm is adopted, which meets the requirements of the National Electrical Manufacturers Association SSL6 (NEMASSL6) dimming standard. 2. Marvell's unique primary current control method is adopted, which does not require optocouplers and related feedback circuits, and provides very high regulation accuracy over a wide AC input range. 3. A high-voltage startup circuit is integrated to supply power at power-up, eliminating the need for external field effect transistors (FETs) and associated power circuits. 4. The dimmer status can be monitored and the dimmer load managed to maintain normal operation through the internal digital core and analog circuitry, eliminating the need for external dimmer bleeder circuits required by existing solutions on the market. 5. Through a unique design approach, it achieves efficiency up to 90%, power factor higher than 0.95 and total harmonic distortion lower than 20%, enabling lighting OEMs and original design manufacturers to easily exceed ENERGY STAR requirements. 6. For isolated and non-isolated LED lamps, flyback and buck-boost topologies are supported. The development of each emerging industry has to go through the process of starting, developing, maturing and declining. The large-scale application of LED intelligent dimming in commercial lighting will inevitably require continuous technological innovation, LED indoor lighting can become mature, and commercial lighting can break the cocoon out.
