Jiangsu market LED light 70% EMC failure

Jiangsu Province Quality Supervision Bureau released the first quarter of 2014, LED lighting products and quality analysis of energy-saving lighting products, 103 batches of LED light pass rate of 60.2%, market sales of 50 batches of products pass rate of only 30%, there are more quality problems.

The sampling, the LED lamp failed to focus on the project focused on electromagnetic compatibility. Senior Engineer Shi Zhaoyang national semiconductor lighting product quality supervision and Inspection Center said that the interference to other household appliances main characteristics of electromagnetic compatibility LED running lights, if not qualified, could lead to the distribution system or connected to this system and other electronic products will not work properly.

Jiangsu Province, the existing types of lighting more than 2000 enterprises, of which, LED lighting appliances manufacturing enterprises more than 500, lighting production enterprises more than 1200, electric light source production enterprise more than 400, ballast, trigger, lamp, lamp base and other accessories production enterprises more than 100. Quality Supervision Bureau of Jiangsu Province recently issued LED lighting products and energy-saving lamps quality report, in which the market sales pass rate of LED is only 30%.

Spot checks 85 batches of energy-saving lamps pass rate of 69.4%

Jiangsu, as one of the important production bases of energy saving light sources in China, has the advantages of complete industrial chain and large number of enterprises." Power source product quality supervision and inspection center engineer Liu Jue told reporters, Jiangsu Province, energy-saving lamps lamp and accessories production enterprise more than 500, mainly distributed in Yancheng, Changzhou, Yangzhou, Wuxi, Suqian and other regions.

According to spot check results show that: this supervision and inspection of energy-saving lamp products 85 batches, covering the market main brands and models, 59 batches of qualified, the pass rate of 69.4%. Among them, the production field of product quality supervision and inspection of 35 batches, 33 batches of qualified, the pass rate was 94.3%; 50 of the market quality risk monitoring, qualified, qualified 26 batches, sampling inspection rate of 52%.

Jiangsu market sales of LED lamp pass rate of only 30%

In the Jiangsu region, LED lighting products accounted for much the same. The supervision and inspection of a total of 103 batches, of which the production field, product quality supervision and inspection of 53 batches, 47 batches of qualified, the pass rate of 88.7%. 50 batches of product quality risk monitoring were carried out, of which 15 batches were qualified, the passing rate was 30%, and there were many quality problems.

According to Shi Zhaoyang, the national semiconductor lighting product quality supervision and inspection center, deputy director of introduction, through the analysis of the Jiangsu unit of production and circulation field sampling results, the quality of the overall status of products in Jiangsu enterprises are better than the current circulation products. At the same time, enterprises in Jiangsu LED lighting products obtained 3C or CQC certification ratio of about 40%, also higher than the circulation of similar products certification ratio. But from the photoelectric performance inspection, in the initial luminous efficiency, power factor, color rendering index and related color temperature and other important performance indicators, our province to achieve high proportion of domestic products is not high.
