34 batches of lighting sources and lamps failed random inspections

On the 17th, the State Administration for Market Regulation notified the national supervision and spot checks on the quality of lighting sources and lamps in 2021. The spot checks found that 34 batches of products were unqualified, and the unqualified discovery rate was 7.9%.

It is reported that this time, 430 batches of products produced by 424 enterprises were randomly checked, involving 3 kinds of lighting sources and lighting products such as fixed general-purpose lamps, self-ballasted LED lamps, and LED control devices.

The unqualified discovery rate of fixed general-purpose lamps was 6.8%

This time, 220 batches of fixed general-purpose lighting products produced by 220 enterprises in 12 provinces (cities) were randomly checked, and 15 batches of products were found to be unqualified. In the past three years, the unqualified discovery rates of this product were 5.8%, 2.5%, and 6.8%, respectively.

This spot check focuses on 8 items such as structure, external wiring and internal wiring, protection against electric shock, durability test, heat resistance, fire resistance and tracking resistance, disturbance voltage (power terminal), radiated electromagnetic disturbance, and harmonic current limit. After inspection, except for the external wiring, internal wiring, and durability test, all other items were found to be unqualified. According to the analysis of technical institutions, the main reasons for the failure are: first, the enterprise has insufficient understanding of the standard requirements of GB7000.1-2015 "Lighting Part 1: General Requirements and Tests", and the product structure design is unreasonable; second, in the production process of the enterprise, the quality control of insulating material and control device components is not in place.

In this key spot inspection, 129 batches of products produced by 129 enterprises in Guangdong Province in the industrial agglomeration area were inspected, accounting for 58.6% of the total number of inspection batches.

Self-ballasted LED lights found a failure rate of 15.1%

This time, 73 batches of self-ballasted LED lamp products produced by 73 enterprises in 7 provinces (municipalities) were randomly checked, and 11 batches of products were found to be unqualified. In the past three years, the unqualified discovery rates of this product were 3.3%, 5.0%, and 15.1%, respectively.

The spot check focused on 7 items including interchangeability, protection against accidental contact with live parts, insulation resistance and dielectric strength after wet treatment, mechanical strength, heat resistance, fire and flame resistance, and harmonic current limits. In the inspection, the unqualified items involved interchangeability, protection against accidental contact with live parts, insulation resistance and dielectric strength after wet treatment, mechanical strength, and harmonic current limits. Among them, 7 batches of products were inspected for harmonic current limit items according to the standard requirements, and 6 batches were found to be unqualified. According to the analysis of the technical organization, the main reasons for the failure are: first, the circuit design of the product is defective, and the electromagnetic compatibility protection measures are insufficient; the space is not fixed firmly or the size of the lamp head does not meet the standard requirements.

This time, we focused on sampling inspections of production enterprises in two industrial agglomeration areas in Guangdong Province and Zhejiang Province, and inspected 49 batches and 12 batches of products respectively. The unqualified detection rates were 16.3% and 25.0% respectively.

The unqualified discovery rate of LED control devices was 5.8%

This time, 137 batches of LED control device products produced by 131 enterprises in 10 provinces (municipalities) were randomly checked, and 8 batches of products were found to be unqualified. In the past three years, the unqualified discovery rates of this product were 0%, 1.5%, and 5.8% respectively.

This spot check focuses on 10 items including measures to prevent accidental contact with live parts, protective grounding device, moisture-proof and insulation, dielectric strength, abnormal state, structure, etc. The unqualified items involve measures to prevent accidental contact with live parts, dielectric strength, abnormal state, heat resistance, fire resistance and tracking resistance, special supplementary requirements for self-contained safety extra-low voltage DC or AC electronic control devices for LED modules. According to the analysis of the technical organization, the main reasons for the failure are: first, the enterprise does not understand the product standard requirements in place, and the product circuit wiring design is unreasonable; second, the enterprise quality control is not strict, and the factory inspection is not strictly carried out according to the standard requirements.

In this key spot inspection, 90 batches of products from 88 production enterprises in Guangdong Province in the industrial agglomeration area were inspected, accounting for 65.7% of the total number of inspection batches. Six batches of products were found to be unqualified, and the unqualified discovery rate was 6.7%.

In response to the problems found in this national supervision and spot check on product quality, the State Administration for Market Regulation requires all localities to seal up and detain substandard products in accordance with the law, order companies that sell substandard products to stop selling the same product, and comprehensively clean up and dispose of substandard products in stock according to law. Unqualified product manufacturers stop the production and sale of the same product, and clarify the rectification requirements, urge the implementation of rectification measures, and organize review in a timely manner. Those suspected of committing a crime shall be transferred to judicial organs in a timely manner. Lawfully include seriously illegal and untrustworthy enterprises into the list of severely illegal and untrustworthy enterprises for management.

The market supervision departments of Guangdong Province and Zhejiang Province are required to carry out special rectification of self-ballasted LED lamp product quality, increase the supervision and inspection of key enterprises within their jurisdiction, comprehensively use various means, maintain a high-pressure situation of quality supervision, seriously deal with quality violations, and focus on raise the quality level.

The local government and relevant departments will be notified of the unqualified products in this random inspection, and effective measures will be taken to urge enterprises to implement the main responsibility for product quality and safety in accordance with the law, and guide enterprises to organize production in strict accordance with standards to maintain product quality and safety.

In addition, strengthen quality and technical assistance. Organize relevant industry organizations and technical institutions to help enterprises find out the reasons in depth, propose improvement measures and solutions, and promote the improvement of industry quality.
