Low pass rate forbidden white LED lighting is still "mainstream"

As the National Development and Reform Commission announced that it will ban the sale of incandescent bulbs of 100 watts or more from October 1, 2012, the LED lighting industry is supported by relevant national policies. Traditional lighting has gradually transformed into LED lighting.

In incandescent delisting other lighting replacement period, in fact, consumer LED lighting is not the absolute resistance, but did not dare to accept. At present, product identification on the LED market is not clear and unclear, and there is also a lack of uniform standards. Faced with jagged products, the Guangdong Provincial Bureau of Quality and Technical Supervision recently conducted spot inspections of LED lighting products.

In this investigation, self-ballasted LED lamp products produced by 21 companies in 7 cities including Guangzhou, Shenzhen, Zhuhai, Foshan, Zhongshan, Huizhou, and Dongguan were used. A total of 23 batches were tested, and 17 batches of unqualified samples were tested. The pass rate was less than 30. %. It is understood that there are many LED market companies scattered, the brand may be as many as thousands, but there are not many real trustworthy brands, industry experts said: "30 yuan product quality is difficult to guarantee."

For current LED lighting products on the market, experts put forward purchase suggestions:

First, look at the product packaging: see if there are product trademarks and certification marks, such as: 3C certification, CE certification, etc., in addition to see if clearly marked the product's rated voltage, voltage range, color temperature, precautions, safety instructions, applicable environment, etc. .

Second, the price comparison: due to the special reasons in the production process of LED lamps, the cost is relatively high, the general domestic LED lamp prices are more than forty or fifty yuan, the import is even higher. In addition to looking at the appearance of the product is not rough, is there no glue is not clean, whether there is a screw protruding plane? Whether the color of the screw is consistent with the color of the shell.

Third, the light after lighting need to carefully observe the lamp color changes, if in a short time, from yellow to white, or from white to blue with white light, such products will have to give up, because There are two possibilities for this situation: one: the power supply problem; two: LED light source selection errors. In addition, the color of the light must be positive, and the light color of the light is the same, ie it does not flash. After the LED lamp is turned on, it can detect the heat dissipation of the product by touching the surface temperature of the product. If the temperature of the product surface continues to rise in one hour, instead of being stable for the longest time in 30 minutes, the product should not be selected due to heat dissipation. , resulting in shortened product life.
