Shanghai trade and Industry Bureau LED lamp sampling results: 26.1% of the failure rate

Recently, the 23 batch of Shanghai city Industrial and Commercial Bureau organized forces to Xuhui, Putuo, Hongkou, Minhang 4 regional 5 stores, 7 professional market, 11 supermarket sales of mobile, fixed, embedded LED lamps were sampling inspection and the quality of the market. After testing, 6 batches of unqualified, unqualified rate was 26.1%, the sampling of portable LED lamp 13 batches, 4 batches of unqualified, unqualified rate was 30.8%; the fixed sampling LED lamp 9 batches, 2 batches of unqualified, unqualified rate was 22.2% sampling; embedded LED lamp 1 batches, no failure detection. Sampling found that Minhang District, Putuo District, a higher rate of unqualified detection, were 50% and 40%. The unqualified items of LED lamps are limited value, external wiring and internal wiring, structure, heat resistance, fire resistance and scratch resistance, marking, etc..

First, the limit value exceeded, there are 6 batches, of which 4 batches can be moved, fixed batch of 2. Sampling found that the power supply terminals of substandard goods more than the national standard limit voltage. Limit values directly affect the surrounding radio, television can not be normal to listen to, watch and instrument control failure. The utility model relates to a disturbance voltage, which belongs to a radio disturbance, which is used for the electric appliances in the range of the frequency band and forms the environmental pollution.

Two external wiring and internal wiring is not qualified, there are 4 batches, are removable LED lamps, which, the external wiring cross-sectional area is not qualified to have 4 batches, the internal wiring cross-sectional area of substandard batches of 1. Sampling found that the cross-sectional area of the conductor of substandard goods were less than 0.5 mm2, less than the national standard value. External wiring and internal wiring is not qualified, once the lamp does not have enough carrying capacity, in the abnormal circuit conditions, easy to overheat.

Three is the structure is not qualified, there are 2 batches, are removable LED lamps. Sampling found unqualified goods are not stable enough, or not enough clamping force, top-heavy easily overturned, unreasonable design, did not meet the standard requirements. The structure of substandard lamps, may lead to electric shock protection failure, may also lead to the fall of the lamp, mounting surface temperature rise, causing the desktop or floor charred, fire, endangering the safety of consumers' personal property.

Four is heat-resistant, fire-resistant and scratch resistant, there are 1 batches. Sampling found that the quality of the switch did not use good insulation materials, heat resistance test, the measured values are not consistent with the national standard value. Fixed electrical components or electric shock protection insulation material must be able to heat resistance, otherwise, easy to deformation, combustion, so that the original protective performance of electric shock protection.

Five mark is not qualified, there are 1 batches. Sampling found that substandard goods no relevant symbols or warning. Mark is not qualified, consumers can not see the relevant mark during the installation of lamps or light source.

According to the sampling results, the business sector has ordered the relevant operators to immediately stop selling substandard goods, a comprehensive clean-up inventory of products, in the sale of products, the deadline to implement corrective measures, supervise the publicity of substandard goods operators in accordance with the relevant laws and regulations actively take measures to protect the legitimate rights and interests of consumers, and according to the investigation on the operators selling substandard commodity.

Meanwhile, the business sector to remind consumers in the purchase, use, maintenance of LED lamps should pay attention to the following points:

First, the purchase of LED lamps should be three". A look at the product identification is complete, its manufacturer name, address, trademark, model, rated voltage, rated frequency, rated power, conform to specifications and check the product model inspection report and safety certificate, electrical parameters are correctly identified; two light power line is the CCC safety certification mark the external conductor cross-sectional area should not be less than 0.75 mm2; three light charged body is exposed, the light source into the holder, the finger should not touch live metal cap.

Two, for children to buy LED lamp, lamp light source to avoid the metal shell to buy high heat, such as incandescent lamp, metal halogen lamp; at the same time, should pay attention to whether the lighting lamp can be smooth enough, tilted about 6 degrees to see whether it is over; to choose lamp protection against electric shock higher category, such as marked "II lamps back" word symbols.

Three, buy the lamp, should carefully check the marker lamps and read the instructions, and then install the use; the use of LED lighting, if it is found that both ends of the lamp tube fluorescent red jump does not shine, according to the source parameters of mark, tube timely replacement of aging; clean maintenance LED lamp, should look for instructions. In addition to the removal of the lampshade or the replacement of the lamp tube lamp, do not easily disassemble the other parts of the lamp, and in the end of the cleaning and maintenance, according to the original will be installed.
