Yesterday, the Jiangsu Provincial Quality Supervision Bureau announced the sampling of LED lamps and energy-saving lamps that were produced locally in Jiangsu and sold in the Jiangsu market. Based on the results of the sampling, the four major problems in the current two lamps market were analyzed. The sampling results show that the quality of LED lamps and energy-saving lamps produced locally in Jiangsu is good, but the qualified rate of LED lamps sold in the market is only 30%, and the pass rate of energy-saving lamps is more than 50%. In addition, the quality supervision department found in the sampling inspection that some inferior energy-saving lamps may have irregularities in processing using “ditch powder†(recycled waste powder). These inferior lamps not only dim the lights, but also hurt their vision. Sampling result 30% energy-saving lamps failed The quality supervision department introduced that they had sampled 103 batches of LED lamps, 53 batches in the production field, and 50 batches sold on the market, covering the mainstream brands and varieties on the market. The test results show that the qualification rate of LED lamps in local production in Jiangsu is 88.7%, while the pass rate of LED lamps sold in the market is only 30%, and there are many quality problems. In the sampling of energy-saving lamps, a total of 59 batches of products were qualified in 59 batches, and the overall pass rate was 69.4%. A total of 35 batches of energy-saving lamps in the production field were sampled, with a pass rate of 94.3%. The situation of energy-saving lamps sold in the market is not satisfactory. Of the 50 batches tested, only 26 batches were qualified, and the pass rate was 52%, just over half. According to the relevant person in charge of the quality supervision department, there are currently more than 2,000 lighting and electrical appliance companies in Jiangsu. Jiangsu is not only one of the important LED production bases in China, but also a number of enterprises producing energy-saving lamps, mainly in Yancheng, Changzhou, Yangzhou, Wuxi, Suqian and other regions. The quality of sampling for the products sold in the market is not good. Liu Wei, an engineer of Jiangsu Provincial Electric Light Source Product Quality Supervision and Inspection Center, firstly, the price of unqualified energy-saving lamps sold in the market is far lower than the production cost of the enterprises in the province. Secondly, many manufacturers of unqualified products on the market are small enterprises or even small workshops. The third is the “export factorâ€, and most of the products of large and medium-sized enterprises are used for export. Liu Wei said that the energy-saving lamp products produced by small enterprises and small workshops in the market that are “not cheap and not beautiful†continue to squeeze market share, and the phenomenon of “bad lights expelling good lamps†has emerged, forming a vicious circle. Detecting problems Poor quality energy-saving lamps may use "ditch powder" In this spot check, the initial luminous efficacy of 20 batches of products produced by Zhongshan Ou Point Lighting Co., Ltd. and Zhongshan Guzhen Tingxuan Lighting Appliance Factory were unqualified. Liu Wei said that the initial light effect is about the problem that “energy-saving lamps are not bright, energy-saving lamps are not energy-savingâ€. Generally speaking, the higher the value of the initial light effect, the brighter the lamp and the more energy-saving. Liu Wei said that in the spot check, they had encountered people who promoted "ditch powder", which may find an answer to the initial failure of light efficiency. Liu Wei introduced that “ditch powder†is recycled waste powder. Some enterprises also use cheap ordinary halogen powder, but in fact, the “three primary color†rare earth phosphors that meet the standard requirements should be used in the formal production process. It is said that small businesses are compressing costs in pursuit of low prices, so they will use “ditch powderâ€. “The sales people we have encountered are from Zhejiang. They say that using trench powder is a hidden rule.†Liu Wei said that the "ditch powder" caused the initial light effect to be unqualified, not only the dim light, the visual acuity, but also the short life, neither saving electricity nor saving money. LED light detects blue light hazard In the supervision and spot check of LEDs, it was found that there were 5 types of blue light hazards in 5 batches of products. Among them, the spotlights of Jiangsu real estate LED lighting products are all qualified for light biosafety. It is reported that the spectrum of LED lamps generally does not have ultraviolet and infrared rays, but the blue component of them will cause damage to human visual network nerve under certain conditions. In general, for LED Blu-ray Class 1 hazards (low risk), the general use distance is greater than 1.5 meters, or non-long-term use (generally less than 2-3 hours) is harmless to the human body. Part of the energy-saving lamp power "virtual high" Liu Wei told the Modern Express reporter that the performance indicators such as whether a lighting product is energy-saving are usually evaluated by indicators such as lamp power, electro-optical power conversion efficiency, and lighting effects. According to reports, in this sampling, 21 sets of products have failed the lamp power and there is a "virtual standard" situation. Liu Wei introduced that some companies will deliberately sell low-power lamps as high-power lamps. The purpose is to sell low-power lamps for high-power lamps, so that consumers will spend money.
