Is there a limit to the price of driving the power supply?

The competition in an industry was not fierce at the beginning, but with the rapid development of the industry, a large number of enterprises emerged. The disorderly competition and homogenization competition became one of the laws of the industry. Under this rule, customers often cannot clearly perceive the differences between products of various enterprises, so "price" becomes the dominant factor, thus forcing enterprises to regard "price" as the main competitive means of differentiation.

The LED lighting industry began to show its enthusiasm in the lighting industry from the “Ten Cities and Ten Thousands” launched by the Ministry of Science and Technology in 2009, and expanded rapidly in the next few years. LED driver power supply , which is one of the core links in the LED lighting supply chain, is no exception. Especially in recent years, the law of homogenization and price war competition seems to be getting worse.

Entering 2014, the domestic and international LED lighting sector policies are positive. The US government's comprehensive ban on the production and import of incandescent lamps has officially entered into force, and the incandescent lamp phase-out plans in Canada, the European Union and other countries and regions have also begun to take effect in batches. Various policies have made LED companies see the dawn of hope. LED practitioners are also more convinced that the first year of LED lighting will be launched in 2014, and the next three to four years will be the golden development period of the LED industry.

In addition to the global favorable policies, the cost reduction driving terminal price drop is also the main factor that triggers the outbreak of the lighting market. Recently, the industry's call for "LED lighting belongs to silk products" is getting higher and higher. Simple, cheap and easy to use are the key points emphasized by these supporters.

"In 2014, the driving power supply should do this: to ensure reliability and safety, to pursue efficiency and constant current accuracy, to minimize ripple and noise, and to properly adjust the linearity rate," said Dong Pei, chairman of Dongguan Feiwang Electronics Co., Ltd. In the pursuit of these, we must consider the price of the product, to ensure that low prices are the constant pursuit of LED light source manufacturers.

Then how should this "price/performance ratio" be measured? What is the "low price" and what is the limit? It is a 1 yuan 3*1W LED bulb built-in drive power supply. It is a high efficiency (90%) 3*1W thyristor dimming power supply 3w drive power supply of 3.8 yuan, or a 5 yuan full open circuit protection and overvoltage protection. Voltage high power factor (0.97) non-isolated lamp drive?

Long life is one of the advantages of LED lighting energy saving. Low price may benefit in a short period of time, but if quality is not enough, quality problems will be sooner or later. According to the market feedback news in the first quarter, due to the safety hazard caused by insufficient insulation of the products, the European Commission issued a consumer warning to the Chinese-made "Goobay" brand LED light chain, and took measures to withdraw the market and recall the product.

In addition, from the results of the quality inspection of the energy-saving lamps and LED bulbs sold in Guangzhou City, the 26 samples of 46 samples were judged as the overall unqualified supervision, and the qualified rate was insufficient. 50%. To this end, industry experts said: "The quality of LED lighting products below 30 yuan is difficult to guarantee." Apply the phrase in "Infernal Affairs": it is necessary to come back sooner.

Of course, China's LED industry can achieve such rapid development in just a few years, and many companies have deeply realized this and have been trying to open up a new route.

In the context of the industry's falling product prices in the domestic market, how to get rid of low-cost, disorderly competition, develop and produce more high-quality, high value-added, cost-effective products become the blue ocean that these enterprises seek in the fierce competition. "Our products are taking the 'high on the' route, positioning the high-end market, not doing low-cost market," said a person in charge of a LED power supply company.

The market is classified by price, and the market can be divided into three grades: high, medium and low, each grade has different consumption needs. At present, the immature LED industry is often very passive in meeting customer needs, which also implies that enterprises need to further improve product performance, price, value and advancement of the industry.
