The single-stage high-voltage linear solution is widely used in various lamps and lanterns due to its simple structure, few peripheral components, simple PCB wiring, and low cost. Mingwei Electronics is now launching a new member of the SM225X series of chips, the single-stage constant power chip SM2251EK. By optimizing the chip design, SM2251SGM effectively solves the problems of multi-lamp parallel oscillation and lamp flicker existing in ordinary single-stage constant power solutions; the chip also integrates 700V high-voltage MOS, which further improves the anti-surge reliability of the solution, and high PF solutions do not need to be Any protection circuit can pass the 700V lightning strike test.

SM2251SGM integrates 700V high voltage MOS;

The high PF scheme can pass the 700V lightning test without any protection circuit;

Multiple lights in parallel without vibration;

Support high PF scheme: PF>0.9;

SM2251SGMSM2251 supports low PF flicker-free scheme: PF>0.5;

No magnetic components are required to meet EMI applications SFI1206SV241-351A;

With constant power compensation function;

Over-temperature protection function improves system reliability;

ESOP8 package.

China's LED lighting products export analysis, the price war has entered a white-hot state

Fourth, China's LED bulb export analysis

In terms of export destination countries, the export of bulb lamps to the United States accounted for the largest proportion, but due to the impact of the trade war, the proportion of bulb lamps exported to the United States declined year-on-year (29.6%); the top ten bulb lamp exporters accounted for 26.4% of the overall proportion , the proportion of CR10 fell by nearly 6% year-on-year.

Analysis of China's LED Lighting Products Export

From January to September 2019, the export value of the top ten export destination countries totaled 10.75 billion US dollars, accounting for 52.1% of the total; the top three exporters were the United States, Germany, and the United Kingdom. The United States was still the largest exporter, accounting for 23.7% of the overall export. The amount fell by 16.7% year-on-year, mainly due to: inventory pressure, the suppression of market demand after the price increase of local lighting manufacturers in the United States under the trade war, and the transfer of some new orders to non-Chinese manufacturers.

Six, China's LED lighting exports to the United States analysis

In terms of products, bulb lamps are the largest single product exported to the United States. The US market is far from meeting its own needs by relying only on its own manufacturing capacity. Basically, it still relies on a large number of imports from China; the top ten companies exporting to the United States account for 15.8% of the total. %, the market concentration is low.
