note! Shanghai 10 batches of LED lamps, explosion-proof lamps and lanterns sampling unqualified

Zhongxin Jingwei December 21, "Shanghai market supervision" 21 news, in response to consumer complaints, reports concentrated and previous sampling found more quality problems of products, recently, the Shanghai Municipal Market Supervision Bureau concentrated on law enforcement forces on 5 online trading platform sales of LED lamps, explosion-proof lamps and lanterns to supervise and spot check. After inspection, 10 batches of unqualified (including 1 batch of explosion-proof lamps).

The sampling unqualified items involved 9 safety indicators: grounding conductor or equipotential conductor connector, explosion barrier joint surface, impact test structure, creepage distance and clearance, external and internal wiring, anti-electric shock protection, insulation resistance and electrical strength, structure, marking, and 2 electromagnetic compatibility indicators: disturbance voltage (power terminal), radiated electromagnetic disturbance (30MHz-300MHz).

Specifically, 1 batch of explosion-proof lamps is not qualified. The unqualified items are grounding conductor or equipotential conductor connector, explosion barrier joint surface, and impact resistance test.

According to the Shanghai Market Supervision Bureau, the grounding conductor or equipotential conductor connector project is unqualified, if the grounding protection fails, the user will have the risk of electric shock, and may make the static electricity on the product shell accumulate too large, thereby igniting the danger of explosion of dangerous gases in the environment; in the flameproof joint surface test, the measured value of the plane joint surface L = 2.98mm (the standard value should be L≥ 15.8mm), which is inconsistent with the national mandatory standard. The explosion-proof joint surface is unqualified, the product does not have explosion-proof function, and may become the ignition source of dangerous places; in addition, after the impact test, the transparent parts of the lamp are broken, and the explosion-proof effect is invalid (the standard requires that after the impact test, the explosion-proof effect should not be invalidated), which is inconsistent with the requirements of the national mandatory standards. If the impact test is unqualified, the product may be damaged in normal use, and then ignite dangerous gases in the environment, and the explosion hazard occurs.

3 batch structure is not qualified. According to the Shanghai Market Supervision Bureau, consumers may touch live parts after opening the light source cavity of lamps, resulting in electric shock hazards.

3 batches of creepage distance and clearance are not qualified. According to the Shanghai Market Supervision Bureau, the creepage distance and clearance projects are unqualified, and the distance between the live parts and the shell is insufficient, which may lead to line failure and short circuit danger.

1 batch of external and internal wiring is not qualified. According to the Shanghai Market Supervision Bureau, the use of wires with insufficient cross-sectional area, insufficient mechanical strength of the wire is prone to the risk of electric shock, but also may overheat the wire, easy to cause fire.

4 batches of anti-electric shock protection is not qualified. According to the Shanghai Market Supervision Bureau, the anti-electric shock protection is unqualified, and consumers may touch the live parts after opening the light source cavity of the lamp, and the risk of electric shock will occur.

6 batches marked as unqualified. The text on the label of the nonconforming product < 2mm in height, or warning symbols or explanatory information such as "Do not look at the light source that is lit" and "The luminaire is not suitable for being covered by insulation material" are missing.

1 batch of disturbance voltage (power terminal) is unqualified; 1 batch of radiated electromagnetic disturbance (30MHz-300MHz) is unqualified. According to the Shanghai Market Supervision Bureau, when the harassment voltage of the lamp exceeds the limit, it may affect the normal operation of electronic and electrical equipment in the same line, resulting in equipment control failure and misoperation.

According to reports, according to the results of the sampling inspection, the Shanghai market supervision and management department has ordered the relevant business operators to immediately stop selling unqualified products, comprehensively clean up the inventory products and products on sale, implement rectification measures within a time limit, unconditionally return and replace the unqualified products that have been sold, and transfer the operators who produce and sell unqualified products to the local market supervision department for investigation and handling according to law.

At the same time, the Shanghai Market Supervision Bureau also issued a prompt for purchasing lamps and lanterns: 1. When purchasing LED lamps, it should be checked whether the product has passed the national CCC certification, and the logo should contain the following contents: trademark or factory name, product model specifications, rated voltage, rated frequency, and rated power. Check whether the connection between the power cord and the product is loose or moving, and check whether the wire is exposed. Check whether the lamp light source is replaceable, the lamp should have a clear logo to inform the user of the replaceability of the light source of the product, for the product that cannot be replaced by the light source, the lampshade can be opened at will to touch the internal live parts when the lamp fails.

2. When purchasing LED table lamps, LED clamp lamps or LED floor lamps, the lamps and lanterns are in the normal working state, and the lamps and lanterns are lifted by hand at an angle of about 6 ° or so, which should not be overturned, check whether the clamping force of the clamping lamp is sufficient, clip the lamp to the wooden board, the glass tabletop, and the pole, and feel whether it can be fixed to these working surfaces steadily.

3. When purchasing explosion-proof lamps, the correct explosion-proof type should be selected according to the use environment, and the nameplate of the explosion-proof lamps and lanterns contains explosion-proof signs, for example, the explosion-proof signs are: Ex dII.C T6 Gb explosion-proof lamps, T6 means that the maximum surface temperature of the product does not exceed 80 ° C, Gb is the EPL grade of the product, indicating that this product can be used normally in dangerous places in Area 1. At the same time, the information of the explosion-proof certificate of the explosion-proof lamp should be checked whether it is consistent with the product. (Zhongxin Jingwei APP)
