With the country's commitment to the United Nations and the determination to carry out environmental protection in the end, China has gradually improved the structure of the lighting market, including the fact that the country did not sell 100-watt and above incandescent lamps after the National Day last year. The LED lighting market seems to have been shot with a strong shot, and sales have gradually increased. However, the lack of supervision in the market has also given some unscrupulous businesses a bad opportunity. The price of LED lamps of different brands is very different. Moreover, due to the lack of relevant standards, there are also problems such as product quality.
Business sweet words
The reporter investigated several professional lighting markets in Tianjin and found that most of the merchants have sold LED lighting as the main product. However, the price of LED lamps of different brands varies greatly. For example, 9-watt LED spotlights range in price from 20 yuan to more than 200 yuan.
“In general, good quality LED spotlights are brighter and more penetrating.†A merchant pointed to his own LED spotlights, and the price of 60 yuan is brighter than the price of 40 yuan. However, another merchant's statement is just the opposite. After the demonstration of the shopping guide, the merchant pointed to a slightly darker LED spotlight, indicating that the lighter softer, more visually comfortable, the better quality, so the price is relatively darker. More expensive. This makes the customer feel like a monk and a monk.
How to distinguish the pros and cons of lamps
When buying LED lamps, we must abide by the opinions given by experts. Consumers should pay more attention to the three aspects of product packaging, price comparison and demonstration effects. Don’t be confused by some discounts and advertisements of the merchants. .
First, look at whether there are product trademarks and certification marks, such as 3C certification, CE certification, etc., in addition to see whether the product's rated voltage, voltage range, color temperature, precautions, safety instructions, applicable environment, etc. are clearly marked. Second, due to the special process in the production process of LED lamps, the cost is relatively high. Generally, the prices of domestically produced LED lamps are above 40 yuan and 50 yuan, and imports are even higher. Third, carefully observe the color change of the lamp. If it changes from yellow light to white light in a short time, or white light turns into white light with blue color, such a product should be abandoned. Because it is very likely to be a power problem or a light source selection error. In addition, the color of the light should be consistent and not flash. After the LED lamp is lit, the heat dissipation of the product can be detected by touching the surface temperature of the product. If the temperature of the product continues to rise within 1 hour, instead of the temperature being stable for up to 30 minutes, do not select the product because the heat is not Good results in a shortened product life. So understand the principle of the luminaire and then know how to choose the luminaire.
Waiting for the country to issue relevant regulations
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.
A person in charge of a well-known brand lighting in Tianjin said, "At present, there are three main problems in domestic LED home lighting. First, the use of aluminum radiators, if not attached to the LED chips, directly affects the service life; second, the brightness The adjustment requires a controller, and the quality of the controller itself is uneven. The third is the core technology of driving power. Only a few companies are willing to invest more in this core technology."
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. 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.
For home use, the most important thing is to use power and life, and 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. However, after mastering the professional attestation knowledge mentioned above, how much has inspired you to purchase, which is beneficial to your better use of energy-saving and environmentally friendly products.
