At the beginning, the competition of an industry is not fierce, but with the rapid development of the industry, a large number of enterprises have emerged. Disorderly competition and homogeneous competition have become one of the laws of the industry. Under this rule, customers often cannot clearly detect the differences between the products of various enterprises, so price becomes the dominant factor, thus forcing enterprises to take price as the main competitive means of differentiation. The LED lighting industry began to emerge in the lighting industry from the ten cities and ten thousand lamps launched by the Ministry of Science and Technology in 2009, and expanded rapidly in the next few years. As one of the core links in the LED lighting supply chain, LED driving power supply is no exception, especially in recent years, the law of homogenization and price war competition seems to be getting worse. Entering 2014, domestic and foreign policies in the field of LED lighting have been favorable. The US government's plan to ban the production and import of incandescent lamps in China has come into effect, and the incandescent lamp elimination plans of Canada, the European Union and other countries and regions have also begun to take effect in batches. Various favorable policies have enabled LED enterprises to see the dawn of hope. LED practitioners are also more convinced that 2014 will open the first year of LED lighting. In the next 3- Four years will be the golden development period of LED industry. In addition to favorable policies, cost reduction drives the decline in terminal prices to be the main factor driving the outbreak of the lighting market. Recently, the industry's call for LED lighting to be a silk product is getting higher and higher. Simple, cheap and easy to use are the key to these supporters. On 2014, the driving power supply should do this: ensure reliability and safety, pursue efficiency and constant current accuracy, try to suppress ripple and noise, and properly adjust the linear rate. Dong Pei, chairman of Dongguan Feiwang Electronics Co. , Ltd. , said, in the pursuit of these, we must consider the price of the product, to ensure that the low price is the constant pursuit of LED light source manufacturers. How should this price/performance ratio be measured? How much is the low price? It is a 3*1WLED bulb lamp with built-in driving power supply in 1 yuan, which is 3. 8 Yuan's high efficiency (90) 3*1 w scr dimming power supply 3w drive power supply, or 5 yuan full voltage high power factor with open circuit protection and overvoltage protection (0. 97)Non-isolated lamp drive? Long life is one of the advantages that highlight the energy saving of LED lighting. Low price may benefit in a short period of time, but if the quality is not up to standard, it will be sooner or later. According to the market feedback in the first quarter, the European Commission issued a consumer warning to the Chinese-made Goobay brand LED lamp chain due to the potential safety hazard due to insufficient insulation of the product, and took measures to withdraw the product from the market and recall it. In addition, according to the sampling results of the commodity quality of energy-saving lamps and LED bulb lamps sold in Guangzhou released by Guangzhou Administration of Industry and Commerce, 26 of the 46 sampling samples were judged to be generally unqualified for supervision, the pass rate is less than 50%. To this end, industry experts said: the quality of LED lighting products below 30 yuan is difficult to guarantee. To paraphrase the sentence in 'Infernal Affairs': it is necessary to return it sooner or later. Of course, China's LED industry has been able to 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 continuous decline in product prices in the domestic market, how to get rid of low prices and disorderly competition, developing and producing more products with high quality, high added value and high cost performance has become the blue ocean that these enterprises are looking for in the fierce competition. Our products take the high-end atmosphere on the grade line, positioning the market, not a low-cost market, a person in charge of an LED power supply company said. The market is classified by price, and the market can be divided into three grades: high, medium and low. Each grade has different consumer demand. At present, the immature LED industry often makes it very passive to meet customer needs, which also implies that enterprises need to further improve product performance, price, value and promote industry progress.
