Shaanxi Provincial Quality Supervision Bureau: E-commerce platform LED lamp sample sampling over 30% failed

    On August 3, the Shaanxi Provincial Quality Supervision Bureau issued the second batch of provincial-level product quality supervision and spot check results. The results showed that the qualified rate of the sampled ordinary lighting LED lamp samples was only 65%, and more than 30% were unqualified, involving fault status and mutual Various items such as changeability, mechanical strength, protection against accidental contact with live parts, initial luminous efficacy/light flux, energy efficiency limit value, power factor, color characteristics, early failure, etc. are not acceptable.

    It is reported that the samples taken from the No. 1 shop, Suning, Tmall, Jingdong and other network platforms, involving daily use and textiles, electronic appliances and other eight categories of 24 kinds of products, including extension cord sockets, non-directional towns for general lighting The pass rate of three kinds of products, such as flow LED lamp and diffused silicon pressure transmitter, is below 70%.

    For the production enterprises whose product quality is unqualified in this spot check, the quality supervision department will deal with it seriously according to law.

    Harbin Market Supervision Administration: 4 batches of fire emergency lights were unqualified

    According to the website of the People's Government of Harbin, the Harbin Municipal Market Supervision Administration recently conducted quality inspections on 10 batches of fire-fighting equipment sold in the urban area, all of which were qualified.

    Sampling inspection of 20 batches of fire emergency luminaries, Nangang District Century Fenghua fire equipment store sales of "Hope of Hope" and other four batches of fire emergency lighting failed, has been ordered to stop selling, and the operator investigated the case.

    This sampling inspection is mainly based on the "Product Quality Law of the People's Republic of China", "Measures for Inspection and Inspection of Commodity Quality in Circulation Fields", "Performance and Structural Requirements for Portable Fire Extinguisher" (GB4351.1-2005S), "Fire Emergency Lighting and Evacuation Instruction System" (GB17945) -2010) and other laws and regulations, technical standards and indicators. Among them, the fire emergency light inspection items include basic function test, charging time, discharge time, emergency lamp working time, repeated conversion time, conversion voltage test, insulation resistance test, withstand voltage test, and voltage fluctuation test. The main unqualified items involve basic functional tests and repeated conversion tests.

    Harbin Consumers Association test found: 5 LED lights mechanical strength or lamp power does not meet the standard

    Recently, the Harbin Consumers Association organized a comparative test of LED bulbs and found that the power or mechanical strength of five sample lamps did not meet the national standards.

    The comparative test samples were purchased by the staff, including 12 brands of Qiangling, OPPLE, PHILIPS, Bull, a, Zhongguang, IKEA, Sunlight, goofoo, Kyle Lighting, FSL Foshan Lighting, Jingcui, etc. 20 LED bulb samples, tested for sample marking, interchangeability, protection against accidental contact with live parts, insulation resistance, dielectric strength, mechanical strength, lamp temperature rise, lamp power, power factor, initial light efficiency, etc. 10 items .

    If the input power is too large, the user will cause the risk of overload when matching the relevant power supply circuit capacity according to the rated power of the appliance, which will cause the heating of the power supply circuit, causing insulation aging and damage, and there is a danger of short circuit in long-term use; If the power is too small, it will affect the performance of the product. The actual power consumption of the luminaire will deviate from the rated power. The deviation describes the consistency between the measured power and the nominal power. Consistency is an indicator for evaluating the quality of such products. The measured power is greater than the manufacturer's nominal power rating, indicating that the product has low power and misleading consumers.

    The relevant standard requires that the actual power consumed should be no more than 110% of the nominal power and not less than 80% of the nominal power. The test found that there were 5 samples whose actual input power deviated from the nominal power rating exceeded this standard.

    The mechanical strength is an index to measure the firmness of the combination of the lamp cap and the lamp body. According to the national standard, the lamp cap should be firmly connected with the lamp body and can withstand a certain torque. If the connection strength between the lamp cap and the lamp housing is too low, the screwing or unscrewing torque when the user installs or replaces the lamp is likely to cause the lamp cap to be detached from the lamp housing, which affects the use of the lamp, and causes the internal wire to break. Short circuit. In the test, the mechanical strength of one of the samples did not match the national standard.

    Jiangsu Provincial Quality Supervision Bureau spot check: the qualification rate of automotive lamps is 97.7%

    It was learned from the Jiangsu Provincial Quality Supervision Bureau that on July 31, the Jiangsu Provincial Quality Supervision Bureau issued the results of quality supervision and inspection of automobile lighting products. Spot checks showed that the qualified rate of automotive lamps was 97.7%.

    The batch of 88 car lights was sampled and 86 batches were qualified, with a pass rate of 97.7%. In the spot check, the light distribution performance of two batches of products was unqualified, involving one category of headlights and rear fog lamps. The light distribution performance has strict requirements on the light shape and each test point. The design of the light mirror and the mirror and the coordination between the two and the light source should be reasonable. The function is to illuminate the road surface and not affect the driver on the opposite side. The line of sight also serves as a reminder to other vehicles.

    The quality supervision department reminds consumers to check whether there is a “CCC” certification mark on the surface of the product when purchasing the automobile lamp, and check whether the information such as certificate, factory name, contact number, and execution standard are standardized and complete. Lamps, mirrors, mirrors should be free of scratches, bubbles, orange peels, etc., lightly shake the lamps by hand without noise, the adjustment screws of the headlights and front fog lamps can be adjusted normally. The headlights, front fog lights, front position lights, and reversing lights are white, the turn signals are amber, and the other lights are red.

    Installation of automotive luminaires, especially gas discharge headlamps and LED headlamps, should be handled by a professional. The replacement lamp should be the same as the original lamp model. After the lamp is replaced, it should be secure and the sealing performance is good.
