Shanxi sampling energy-saving lamps pass rate 80%

Recently, the Shanxi Province Quality Supervision Bureau announced the result of the product quality supervision and inspection of the province in the third quarter of 2011.

Among them, 30 batches of energy-saving lamps in Taiyuan were supervised and spot checked, and 24 batches were qualified. The pass rate for spot checks was 80%. Unqualified six batches, there are major quality problems: First, the mechanical strength can not meet the standard requirements. In this spot check, there were 1 batch of products that had fallen off during the test, which led to the exposure of live parts inside, which would cause great potential safety hazards to consumers. Second, the lamp power was unqualified. The lamp power determines the power consumption of the energy-saving lamp. According to national standards, the power of energy-saving lamps must be clearly stated on the packaging of energy-saving lamps. The smaller the difference between the measured power value and the nominal value of the product, the higher the production accuracy of the product. There were a total of 3 batches of products failing to meet the standard in the spot check; third, the energy efficiency labels were unqualified. The energy efficiency logo clearly indicates the energy efficiency rating of household appliances, and the energy efficiency level is an important indicator to determine whether the household appliances are energy-efficient. The higher the energy efficiency of the products, the better the energy-saving effect and the more power saving; the fourth is that the color characteristics cannot be achieved. standard requirement. The color feature index includes two items of color rendering index and color tolerance. In this spot check, there were 2 batches of products which were not up to the standard; 5 was the failure of harmonics. Harmonics are harmful high-frequency harmonic currents generated during operation of the circuit. These high-frequency harmonic currents can cause harm to other electrical equipment and the power grid itself through the public power grid. Excessive current harmonics will cause the device to generate heat, increase losses, shorten its service life, and even cause malfunction or burnout. There were 5 batches of product harmonics in the spot check. Such products will not only leave hidden dangers for consumers, but also affect the safety of public facilities.

It is understood that the root causes of these problems are threefold: First, the quality of employees is low, the production process is not strictly controlled, and the necessary inspection methods are lacking. Second, some small-scale enterprises do not have the ability to develop their own products. They only buy parts from the accessories market to assemble and simply imitate the products of famous companies. Third, some companies are trying to deceive consumers in order to extract huge profits and produce low-quality, low-cost energy-saving lamps. In this spot check, the Liangmeijia brand energy-saving lamps produced by the Zhongshan Qipu Lighting and Lighting Appliance Factory, which are distributed by the Ministry of Fine Arts Lighting and Lighting Department of Taiyuan Qiangqin District, have their mechanical strength in the test, the lamp caps fall off, and the sign information is incomplete. No energy label was attached, and the color rendering index and harmonics of its performance did not meet the requirements of the standard.
