Yuan Lei AC drives LED module to open new era

2016 is a leap year with 366 days. Its first day is Friday, the Spring Festival of 2016 is February 8th, and the zodiac is monkey. There was no spring in the lunar calendar, so it was also called spring free year.

Speaking of this, you will say, what is the relationship between this and the module? Yes, I just want to say that in the LED packaging industry, after many years of ups and downs, such as roller skating and cost, such as roller coaster, there are too many words to describe this industry. Nowadays, the integration of modules (linear integration) is in China. It has been circulated in many countries around the world. As LED enters large-scale commercial and home lighting, customers have more stringent requirements for product performance, price and reliability.

However, who will be the main controller of this linear module and wait for the eyes. LED high voltage linear constant current IC and AC drive LED module. On the one hand, the luminous efficiency of LED is continuously raised and the price is constantly decreasing. On the other hand, more requirements for the life of LED lamps are also put forward. In the eyes of ordinary people, the life of LED itself is very high, but the actual life is very low, often due to the low power supply life. At present, most of the lamps and lanterns solutions are light source + power + shell mode, and the power supply is similar to the traditional switching power supply principle, the circuit is complex, and the electronic components are more. The production process is complex, the production cost is high, and the probability of failure is high. In order to reduce costs, many high-voltage linear constant current IC solutions are introduced by many companies in the industry. The scheme does not require high-frequency transformers. Some schemes do not require electrolytic capacitors, simplify the process flow of lamps and lanterns, and achieve the goal of directly driving LED with commercial power, and the cost is greatly reduced.

At present, Yuan Lei Technology Co., Ltd. has launched part of the module plan, many LED industry companies have adopted. The company's main push module has achieved PF>0.98, efficiency >0.95, 80V-265V full voltage support, no strobe, and also can finish intelligent dimming with switch only, and the whole set of programs will be less than 3 yuan. Single IC supports 25W, and more than 25W can be connected in parallel. At present, the performance of switching power supply has reached or surpassed that of the industry. At present, the marketing work has been carried out.

The high voltage light source with the advantages of independent core technology is combined with professional control IC, simplifying the drive design, achieving stable output of circuit current, shortening production material management cost and assembling process cost in time, with obvious cost advantages and high cost performance. It is suitable for fluorescent lamps, bulb lamps, down lights and ceiling lamps. Lights, etc.

Product characteristics:

Design advantages: the integrated design of the power supply has no inductance components; the driving IC adopts 500V high pressure technology, the efficiency is as high as 89%, and the life span is as long as 30000 hours.

2. High temperature protection, to set the 120 degree C limit temperature automatically to 50% power or shut off power output; reduce production process, easy to produce and maintain, according to the needs of users, design customized PCB board size. Users can choose one or more segments according to their needs, such as the combination of urban and rural areas, unstable voltage scenes in Southeast Asia and so on.

The LED industry has been very mature, and the standard specifications are being further generalized. In the future, the development of general lighting will become more universal, homogeneous and standardized. While the power supply module lighting has accumulated time, it will start to show its strong vitality. The "de power" scheme will become an indispensable force in the LED lighting drive market. In the next 1~2 years, the power supply products will account for 30%. -40%'s market share.

I hope that when 2016 comes, there will be a hundred flowers in the industry.
