The town enterprise on the black list, quality inspection as the Buddha is seated.

13, 2009, the official website of the Jilin Provincial Bureau of industry and Commerce released the field of LED lamps commodity quality sampling results show that the group of samples in the sample of the 43 groups were judged to be unqualified, the failure rate was 72.88% ().

Jilin provincial Trade and Industry Bureau commissioned the Jilin Municipal Bureau of industry and Commerce on behalf of Guangdong, Foshan, Shenzhen and other places 28 companies engaged in the production and sale of LED lamps were spot checks on the. The commodity quality inspection according to GB7000.1-2005 "GB 7000.1-2007 lamps first part General requirements and test", GB/T24908-2010 "general lighting self ballasted LED lamp performance requirements", GB24906-2010 "general lighting self ballasted lamp above 50V LED safety requirements", "GB24819-2009 general lighting LED module", "general safety requirements GB/T24823-2010 LED lighting module performance requirements" packaging of goods or the express enterprise standard or enterprise's quality commitment was detected. The indexes, such as the sign, the lamp power, the initial light effect, the power factor, the color characteristic, the insulation resistance and the dielectric strength are measured. According to the sampling results, the main unqualified items are signs (signs, markings), lamp power, color characteristics, dielectric strength, electrical strength. Among them, there are 16 groups of samples with unqualified electrical strength.

From the view of the classification of electrical, LED fluorescent lamp belongs to the class II anti shock type, which requires LED fluorescent lamp input to touch, and input to the mounting surface between the need to meet the level of reinforced insulation insulation resistance and dielectric strength requirements. At present, a lot of LED fluorescent lamp in the insulation resistance test can be passed, but the strength of the test, however, is mainly the built-in power transformer selection and the LED module aluminum substrate installation location caused by. A lot of enterprises for cost savings or high power efficiency to choose to use the non isolation transformer, which will lead to between the input and output of the built-in power supply can not meet the level of reinforced insulation dielectric strength requirements. At the same time, due to the direct contact between the aluminum substrate and the metal shell of the LED module, the insulation level between the input and the accessible parts can not meet the requirements of the strength of the insulation.

For sampling inspection results unqualified LED lamps and lanterns, the business sector has been ordered by the relevant business operators under the cabinet, and in accordance with relevant laws and regulations to investigate.
