Yesterday, the Guangdong provincial quality supervision bureau released the results of supervision and spot checks. Among them, 51 batches of LED street lamps and light source controllers were found to be unqualified in 20 batches, and the rate of unqualified products was 39. 2. The reporter found that in the list of unqualified enterprises and products notified, many enterprises were included in the catalogue of recommended products for street lamps in green lighting demonstration cities last year. In the unqualified items of LED street lamps and light source controllers, dustproof and waterproof are more unqualified, involving 6 batches. External wiring and internal wiring are unqualified, involving 7 batches. Sampling inspection of 5 batches of LED in Chengdu is to do a good job in the promotion of LED products, steadily improve the quality of LED products, and promote technological innovation and industrial development, from October to this year, Chengdu Municipal Bureau of Quality and Technical Supervision conducted a special supervision and spot check on the quality organization of LED lighting, LED display products and photovoltaic modules throughout the city. A total of 18 batches of LED lighting, LED display and photovoltaic module products produced by 13 enterprises were randomly selected (Including regular supervision of 8 companies 11 batches) After inspection, the physical quality is qualified for 15 batches, and the pass rate of physical quality is 83. 3, higher than 2011 3. 4 percentage points. Among them: 5 batches of photovoltaic modules were randomly selected, and the qualified rate of physical quality was 100; There are 11 batches of LED lighting products, and the qualified rate of physical quality is 81. 8; LED display products in 2 batches, the physical quality pass rate is 50. Judging from the results of this special spot check, the qualified rate of physical quality products is 83. 3, although it is 3 higher than 2011. 4, but the overall quality problem is still more prominent. A total of 11 batches of products from 8 enterprises were randomly selected, and 7 batches were qualified, with a pass rate of 63. 6, physical quality qualified 9 batches, physical quality pass rate is 81. 8. The main test indicators are: signs, protective grounding devices, measures to prevent accidental contact with live parts, moisture and insulation, dielectric strength, structure, screws, intercepting parts and connectors, lamp power, power factor, initial luminous efficiency/luminous flux, color characteristics, interchangeability, protection against accidental contact with live parts, insulation resistance and dielectric strength after wet treatment, mechanical strength, harmonics, etc.
