In 2021, the State Administration for Market Regulation organized and carried out national supervision and spot check on the quality of lighting sources and lamps.The situation of spot check is hereby notified as follows: 1. Basic information (1) General situation of spot check.This time, 430 batches of products produced by 424 enterprises were randomly checked, involving three kinds of lighting sources and lamps, such as fixed universal lamps, self-ballast LED lamps and LED control devices.34 batches of products were found to be unqualified by spot check (see the attachment for details), and the unqualified detection rate was 7.9%.(2) Tracking spot checks.This time tracking spot check to the last unqualified enterprises 3, this spot check did not find unqualified.(1) The unqualified rate of fixed general lamps and lanterns is 6.8%.The spot check of 220 batches of fixed general lighting products produced by 220 enterprises in 12 provinces (municipalities) found that 15 batches of products were unqualified, the unqualified detection rate was 6.8%, up 4.3 percentage points compared with the last spot check.In recent three years, the rate of unqualified products were 5.8%, 2.5% and 6.8% respectively.The spot check focus on structure, exterior wiring and internal wiring, prevent to get an electric shock, durability test, heat resistant, fireproof and resistance to the mark, disturbance voltage (power terminal), electromagnetic radiation harassment, 8 projects such as the harmonic current limits, the inspection in addition to the exterior wiring and internal wiring, durability test 2 project, other projects are found unqualified.According to the analysis of the technical organization, the main reasons for the unqualified are as follows: first, the enterprise does not fully understand the standard requirements of GB7000.1-2015 “Lamps and Lanterns Part 1: General Requirements and Tests”, and the product structure design is unreasonable;Second, in the production process of enterprises, the quality control of insulating parts materials and control device components is not in place.This time, 129 batches of products produced by 129 enterprises in Guangdong province, an industrial agglomeration area, were inspected, accounting for 58.6% of the total number of inspected batches. Nine batches of products were found to be unqualified, with a detection rate of 7.0%.(2) The unqualified detection rate of self-ballast LED lamp was 15.1%.This time, 73 batches of self-ballast LED lamp products produced by 73 enterprises in 7 provinces (cities) were randomly checked, and 11 batches of products were found to be unqualified, with the unqualified detection rate of 15.1%, up 10.1 percentage points from the last spot check.In recent three years, the unqualified detection rates of this product were 3.3%, 5.0% and 15.1%, respectively.This spot check focuses on 7 items such as interchangeability, accidental contact with live parts protection, insulation resistance and dielectric strength after wet treatment, mechanical strength, heat resistance, fire and flame prevention, harmonic current limits, etc.Nonconforming items include interchangeability, protection against accidental contact with live parts, insulation resistance and dielectric strength after wet treatment, mechanical strength, harmonic current limits.Among them, 7 batches of products were tested for harmonic current limit items according to the standard requirements, and 6 batches were found to be unqualified.Through the analysis of technical institutions, the main reasons for unqualified: first, there are defects in the circuit design of the product and insufficient electromagnetic compatibility protection measures;Second, the insulation between the product’s accessible metal shell and the electric parts in the lamp body is insufficient;Three is the lamp holder and lamp body fixed between the firm or lamp holder size does not meet the standard requirements.This time, 49 batches of products and 12 batches of products were randomly checked from the manufacturing enterprises in guangdong province and Zhejiang Province. The unqualified detection rate was 16.3% and 25.0%, respectively.(3) LED control device unqualified detection rate is 5.8%.This time, 137 batches of LED control device products produced by 131 enterprises in 10 provinces (cities) were randomly checked, and 8 batches of products were found to be unqualified, with the unqualified detection rate of 5.8%, up 4.3 percentage points from the last spot check.In recent three years, the unqualified detection rates of this product were 0%, 1.5% and 5.8% respectively.This spot check focuses on 10 items such as measures to prevent accidental contact with live parts, protective grounding device, moistureproof and insulation, dielectric strength, abnormal state and structure. Unqualified items involve measures to prevent accidental contact with live parts, dielectric strength, abnormal state, heat resistance, fire resistance and creepage resistance.Particular supplementary requirements for free-standing safe ultra-low voltage DC or AC electronic controls for LED modules.Through the analysis of technical institutions, the main reasons for unqualified: first, enterprises do not understand the requirements of product standards in place, and the design of product circuit wiring is unreasonable;Second, the enterprise quality control is not strict, not strictly in accordance with the requirements of the factory inspection.This time, 90 batches of products from 88 manufacturing enterprises in Guangdong province were randomly inspected, accounting for 65.7% of the total number of inspected batches. Six batches of products were found to be unqualified, and the unqualified detection rate was 6.7%.Relevant requirements in view of the problems found in the national supervision and sampling inspection of product quality, the market supervision bureau (department, committee) of all provinces, autonomous regions, municipalities directly under the central government and xinjiang production and construction corps shall do the following work :(1) strengthen the handling of the results of sampling inspection.In accordance with the Product Quality Law of the People’s Republic of China and the Interim Measures for the Administration of Supervision and Sampling Inspection of Product Quality, we shall handle the results of supervision and sampling inspection well.Seal up and detain the unqualified products according to law, order the enterprises selling the unqualified products to stop selling the same products, comprehensively clean up and dispose of the unqualified products in stock according to law;Order the manufacturer of the unqualified product to stop producing and selling the same product, clarify the rectification requirements, supervise and urge the implementation of the rectification measures, and organize the review in time.Those suspected of crimes shall be transferred to judicial organs in a timely manner.Enterprises seriously violating laws and trust-breaking shall be included in the list of seriously violating laws and trust-breaking enterprises for management according to law.The results shall be recorded in the E-CQS system and submitted to the general Administration.The administration will strengthen follow-up supervision, according to the situation of the local results of the treatment.(2) Carry out special quality control.Market supervision departments in Guangdong province and Zhejiang Province should carry out special rectification of self-ballast LED lamp product quality, strengthen supervision and inspection of key enterprises within the jurisdiction, comprehensively use a variety of means to maintain high pressure quality supervision situation, seriously deal with quality violations, and strive to improve the quality level.3. We will urge the implementation of principal responsibilities.Local governments and relevant departments will be notified of the unqualified products in this spot check, and effective measures will be taken to urge enterprises to fulfill the main responsibility for product quality and safety in accordance with the law, guide enterprises to organize production in strict accordance with standards, and maintain product quality and safety.(4) Strengthening quality and technical assistance.Organize relevant industry organizations and technical institutions to help enterprises find out the reasons in depth, put forward improvement measures and solutions, and promote the improvement of industry quality level.Attachment: Quick response, timely update access to information sources around you by Speaking New Language editor by Luna Review by Li Zhuang and Jiang Shuai
