Yesterday, the Guangdong Provincial Quality Supervision Bureau issued the results of the supervision and random inspection. Among them, the spot test of 51 batches of LED street lamps and light source controllers found that 20 batches were unqualified, and the rate of unqualified products was 39.2. The reporter found that the notified unqualified enterprises And a list of products, a number of companies were included in the green lighting demonstration city street lamp recommended procurement catalogue last year.
In the unqualified LED street lamp and light source controller, the dustproof and waterproof are not qualified, involving 6 batches. External wiring and internal wiring are the most unacceptable, involving 7 batches.
Chengdu sampling 5 batches of LED failed to do a good job in the promotion of LED products, steadily improve the quality of LED products, promote technological innovation and industrial development, Chengdu Quality and Technical Supervision Bureau in the city from September to October in the citywide LED A special supervision and spot check was conducted on the lighting, LED display products and PV module quality organization.
This time, a total of 18 batches of LED lighting, LED display and photovoltaic module products produced by 13 companies (including 11 batches of 8 enterprises in regular supervision) were examined. After inspection, 15 batches of physical quality were qualified, and the pass rate of physical quality was 83.3. , an increase of 3.4 percentage points over 2011. Among them: 5 batches of PV modules were inspected, the pass rate of physical quality was 100; 11 batches of LED lighting products, the pass rate of physical quality was 81.8; 2 batches of LED display products, the pass rate of physical quality was 50.
According to the results of this special spot check, the pass rate of physical quality products is 83.3. Although it is 3.4 higher than that in 2011, the overall quality problem is still outstanding.
A total of 11 batches of products were selected from 8 enterprises, and 7 batches were qualified, the pass rate was 63.6, and the quality of the products was 9 batches. The pass rate of physical quality was 81.8. The main test indicators were: signs, protective grounding devices, and prevention of accidental contact with live parts. Measures, moisture and insulation, dielectric strength, construction, screws, shut-off components and connections, lamp power, power factor, initial efficacy/light flux, color characteristics, interchangeability, accidental contact with live parts, after wet treatment Insulation resistance and dielectric strength, mechanical strength, harmonics, etc.
