LED lamp price difference continues to expand

Since the ban on the sale of 100-watt and above incandescent lamps in China, the LED lighting market seems to have been given a shot in the arm, and the sales volume is gradually rising. However, the relevant departments found in a random inspection that the failure rate of energy-saving lamps was as high as 68. 75. The reporter recently visited and found that the prices of LED lamps of different brands vary greatly. Since there is no relevant standard at present, the uneven quality of products also makes consumers look like flowers in the fog. It is known that energy-saving lamps are not energy-saving. It is understood that the state has encouraged the use of energy-saving and environmentally friendly products in recent years and has introduced relevant subsidy policies. Compared with traditional lighting lamps, energy-saving lamps are increasingly welcomed by consumers due to their energy-saving and environment-friendly characteristics. Due to the low market entry threshold for energy-saving lamps, the process is relatively simple, and the quality of products is uneven, many consumers cannot identify their advantages and disadvantages. In a random inspection, the relevant departments found that the unqualified energy-saving lamps mainly had problems in product marking, anti-electric shock protection, mechanical strength, lamp power, and energy efficiency level. This not only has the possibility of affecting human health, but also may lead to the risk of electric shock, posing a threat to the safety of consumers. The reporter found that the unqualified rate of the energy-saving lamps was as high as 68. 75, 11 of which have energy efficiency labels that do not conform to CEL-005 implementation rule requirements. In other words, these energy-saving lamps on the market are known to be energy-saving, but they are actually not in line with publicity. Relevant personnel explained that the main problems existing in the unqualified energy efficiency logo are summarized as follows: first, the product specifications and models are inconsistent with the energy efficiency logo; second, the nominal power of the product is inconsistent with the energy efficiency logo, third, the size of the energy efficiency label does not meet the standard requirements. Fourth, the measured initial light efficiency does not meet the marked energy efficiency level requirements. Fifth, the measured initial light efficiency does not meet the marked initial light efficiency requirements. The main reason is that some small enterprises have a low level of technology research and development, and the product performance indicators do not meet the standard requirements. At the same time, enterprises do not know enough about energy efficiency labels, and even do not pay attention to them, resulting in energy efficiency labels not meeting the requirements. The price is chaotic. The reporters visited several professional lighting markets in the city yesterday. Most of the merchants have sold LED lighting as the main product. However, the reporter found that the prices of LED lamps of different brands vary greatly. Take a 9-watt LED spotlight as an example, the prices range from 20 yuan to more than 200 yuan. Generally speaking, LED spotlights with good quality are brighter and more penetrating. A merchant pointed to his own LED spotlights and told reporters that the price of 60 yuan is brighter than the price of 40 yuan. However, another merchant's statement is just the opposite. After giving the reporter a demonstration, the merchant pointed to the slightly darker LED spotlight and said that the light was softer and the vision was more comfortable, certainly the quality is better, so the relatively dark price is more expensive. In terms of service life, many merchants claim that the life of LED bulbs can reach 20 thousand to 30 thousand hours, and the family service life is 8 to 10 years. However, the reporter saw that the shelf life of most LED lamps is only two years. There is no national standard with uneven quality. Experts in the industry said that there are many scattered LED market enterprises in our country, and there may be as many as thousands of brands, but there are not many truly trustworthy brands, the quality of products below 30 yuan is difficult to guarantee. At present, there are three main problems in domestic LED household lighting. One is the multi-purpose aluminum radiator, if it is not tightly attached to the LED chip, it will directly affect the service life; Second, the adjustment of brightness requires a controller, and the quality of the controller itself is uneven; Third, for the core technology of driving power supply, only a few enterprises are willing to increase investment in scientific research. The person in charge of a well-known brand of lamps in Daqing said. For household use, the important thing is the use power and service life, and these indicators can only be measured with professional instruments. Ordinary consumers only demonstrate through sales personnel, it is difficult to identify the quality of the product. The staff of the relevant departments said that at present, there is no uniform standard for China's LED industry, and the quality of products is uneven. As China's semiconductor lighting industry is in the early stage of development, with rapid changes in technical routes and rapid improvement in product performance, some product standards cannot keep up with the development of product performance, however, the formulation of basic standards such as reliability test methods needs more in-depth research, so the formulation of LED lamp standards needs a longer period.
