Since the ban on the sale of 100 watts and more incandescent lamps on October 1, last year, the LED lighting market seems to have been shot a strong shot, and sales are gradually rising. However, the reporter recently found that the price of LED lamps of different brands is very different, and, because there are no relevant standards at present, the uneven quality of products also allows consumers to buy and look like flowers.
Price confusion business is not the same
The reporter visited several professional lighting markets in Binhai, and most of the merchants have sold LED lighting as the main product. However, the reporter found that the price difference of LED lamps of different brands is very different. Take 9-watt LED spotlights as an example, the price ranges from 20 yuan to 200 yuan. “In general, good quality LED spotlights 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 a demonstration to the reporter, the merchant pointed to a slightly darker LED spotlight, indicating that the lighter softer and more comfortable visual quality is better, so the price is relatively darker. More expensive.
In terms of service life, many merchants claim that the life of LED bulbs can reach 20,000-30,000 hours, and the service life of families is more than 8-10 years. However, the reporter saw that the shelf life of most LED lamps and packaging is only 2 years.
There is no national standard quality
According to industry experts, at present, there are many LED market enterprises in China, and there may be thousands of brands, but there are not many brands that are truly trustworthy. The quality of products below 30 yuan is difficult to guarantee.
"At present, there are three main problems in domestic LED home lighting. One is to use aluminum radiators. If it is not tightly attached to LED chips, it will directly affect the service life. Second, the brightness adjustment requires a controller. The quality of the controller itself is uneven; the third is the core technology of driving power supply, only a few companies are willing to increase scientific research investment in this core technology." A person in charge of a well-known brand lighting Tianjin said.
“For home use, the most important thing is to use power and longevity. These indicators can only be measured with professional instruments. It is difficult for ordinary consumers to identify the quality of products only through sales personnel demonstrations.†Tianjin University Liu Tiegen, deputy director of the Optoelectronic Information Technology Science Laboratory, pointed out that at present, there is no uniform standard for China's LED industry, and the quality of its products is uneven. As China's semiconductor lighting industry is in the early stage of development, the technological route changes rapidly and the product performance improves rapidly, which makes the pace of some product standards unable to keep up with the development of product performance, and the formulation of basic standards such as reliability test methods requires more in-depth research. Therefore, the development of LED lighting standards requires a longer period.
