3.15 is coming, LED is fake at the time. Although the LED lighting has a high-tech aura, it has repeatedly reported that the quality of LED products is not enough, but it has been criticized by consumers, so that we have not enjoyed the benefits of energy saving and environmental protection, but have suffered from the inferior products. Products with low quality and low price have seriously affected the reputation of LED in the market and become a roadblock for the popularization of LED lamps. Xiaobian here has simply sorted out the problems of product quality exposed in the LED field, and aims to remind enterprises that in order to win the recognition of consumers, they need to work harder on product quality.
315 investigation: LED enterprise quality door frequency is now 315 this year, I believe many people still remember the last year's 315 party, its no problem in the LED field, but the LED industry companies can not be lucky. For the following exposed problems, companies and industries must take it seriously and pay attention to it.
1. AQSIQ: LED lighting products fail to reach 20
On the eve of the Spring Festival in 2014, LED lights that are both environmentally friendly and of quality can be a hassle. When the discussion about the possible radiation of energy-saving lamps has not been eliminated, LED lighting products of famous brands such as Philips and Delixi have been exposed to the scandal of the quality supervision of the State Administration of Quality Supervision, Inspection and Quarantine, and the LEDs are pushed to the market. The cusp of public opinion has also caused more doubts about the energy-saving effect of LED lights.
On January 24, the State Administration of Quality Supervision, Inspection and Quarantine announced the results of the 2013 national inspection of LED lighting product quality, Mikia Mingkai Lighting, DELIXI, Beiguang, Harmony Optoelectronics, Unilumin, PHILIPS, HOYOL and other brand products on the list of unqualified.
It is understood that the General Administration of Quality Supervision, Inspection and Quarantine has conducted a total of 108 batches of LED lighting products produced by 82 enterprises in 10 provinces and municipalities in Beijing, Shanxi, Liaoning, Shanghai, Jiangsu, Zhejiang, Fujian, Hubei, Guangdong and Sichuan. The product range includes Self-ballasted LED lights for LED downlights and general lighting. Mainly in accordance with GB7000.1-2007 "Lighting Part 1: General Requirements and Tests" and GB24906-2010 "General Lighting 50V Self-ballasted LED Light Safety Requirements" and other standard requirements, respectively, structure, external wiring and internal wiring, Items such as electric shock protection, durability test, heat resistance, fire resistance, marking, interchangeability, mechanical strength, power terminal disturbance voltage, radiated electromagnetic disturbance, harmonic current, etc. were examined.
Of the 108 batches of 82 brands examined, 22 of them produced 22 batches that did not meet the standard, and the failure rate reached 20. The unqualified items involved signs (safety), power terminal disturbance voltage, and radiated electromagnetic disturbance. , interchangeability, external wiring and internal wiring (external wiring cross-sectional area), mechanical strength, heat resistance, etc. Particularly striking is that the two famous brands of Philips and Delixi have appeared in the quality black list. The reason for the failure is that the interchangeability has not met the national standards.
2, Chengdu LED lighting monitoring failed last year results Sichuan Province Chengdu Industrial and Commercial Bureau in the fourth quarter of 2013 to Chengdu Jinjiang, Qingyang, Chenghua, Wenjiang, Chongzhou, some electrical appliances integrated market, lighting professional market and shopping malls sold lights and lamps Quality monitoring. The results show that Huizhou NVC, Otlan, Xuyang Lighting, Bean Point Light, Haohao, Lei Shuo and other brand names are not qualified.
The industry and commerce department indicated that the operator has been ordered to place the unqualified goods in the cabinet and investigate and deal with the illegal acts of distributing unqualified goods according to law. At the same time, the operator is required to carry out rectification, and it can be listed and sold after being rectified and rectified.
3, domestic LED lights fall into the quality door Canada to implement the recall Recently, the Canadian Ministry of Health, CanadianTire company jointly announced the voluntary recall of the Chinese-made mini LED holiday lights.
The recalled product name is Mini LED Holiday Decoration Light, the product model is LED-18-QY3-100/4-W-S17, and the production code is 151-0781. From September 2013 to November 2013, it was sold at CanadianTire Company of Canada. .
The number of recalled products sold in Canada was approximately 875. The reason for the recall is that the metal contacts of the LED bulbs have quality defects and pose a safety hazard.
4, LED lighting projects are also frequently complained Although the past year, the domestic LED public lighting market is in full swing, but it can not be ignored that the vicious competition among LED companies, product mismatch and quality problems are also endless.
In the LED engineering lighting renovation projects that have been completed in various parts of the country in the past two years, many LED street lighting renovation projects have experienced quality problems. For example, Nanchang Bayi Avenue, Jinsha Street in Jincheng City, Zhejiang Province, Jinsha Street, and Guancheng Street in Dongguan have been frequently complained of LED lights.
In 2013, the LED street lighting project of the 2 billion yuan administrative village street in Shanxi has attracted widespread attention in the industry. Many successful LED companies have said that the cost is too high, the profit is too low, and the southern enterprises with lower cost are selected to do it. Some companies even choose to return the bid after winning the bid.
Analysis of the problem: the lack of standards, the confusion of certification The above events can be seen that the main responsibility of the frequent quality problems of LED lamps lies in the fact that enterprises, enterprises and manufacturers have lack of control over product quality, or intend to cut corners on winning products. However, a frequently overlooked phenomenon is that some local governments require bidding companies to ensure that high-quality, high-performance LED lighting products must meet the requirements of high quality and high performance. However, when bidding, the price is quite low. It is difficult for suppliers or manufacturers to make considerable profits. At the same time, the lack of industry standards and testing certification is more confusing, and it has also led companies to be confused about the quality of the product.
1. Which of the standards should be subject to?
In recent years, China has attached great importance to the standardization of semiconductor lighting from the country to the local. The standardization and revision work of units at all levels has progressed rapidly. China's semiconductor lighting and LED standards have basically covered all aspects of the industrial chain.
For the promulgation of these standards, a considerable number of people in the industry believe that these national standards and standards have been applied only to traditional lighting products, LED lighting products are not applicable, based on this guiding ideology, from LED power supply to LED lighting products, There is no national or industry standard system. The quality supervision bureau's supervision of LEDs is based only on conventional application indicators, and it is impossible to judge which is better and which is worse, but the energy-saving effect of LEDs is obvious. If used as decorative lights, LEDs can save energy by 60 to 80 than energy-saving lamps. Energy saving 40 to 50 for lighting applications. However, the light decay (light attenuation) of LEDs is also obvious.
Many international standardization organizations have formulated various standards, which reflect the situation of giving full attention to standardization, but some of them have repeated and contradictory problems, especially some applications are affected by traditional industries and standard technology interfaces. Technical blind spots cause unscientific standards.
Standards should be unique, but there are many standards and systems in the LED industry. Enterprises are not keen on standards. Most of the current LED lighting products are in a non-standardized form. The lack of standards leads to the lack of evidence for product design, and the confusing product technology makes it difficult to support upstream and downstream, which hinders the large-scale application and industrial development of products.
2, the quality of suspected detection deterrence should be force from September 1, 2013, all LED lighting products entering the EU market must comply with the EU's new energy efficiency standards, in order to affix the CE label. The implementation of the new directive has led to new changes in the test certification rules. In the face of new directive requirements, how can we pass relevant test certifications quickly and efficiently? Many LED companies have shown a lot of confusion, but what is more confusing in the industry is that many domestic and international well-known testing and certification organizations have different understandings and test methods for the new ErP energy efficiency instructions. They are quite chaotic and chaotic, making LED products Export companies do not know how to choose.
The standard chaos has seriously affected consumers to accurately judge the quality of a product, so that consumers are hesitant and guilty when choosing LED lamps. However, LED lamps with such excellent performance are not highly recognized by consumers. Why good products can't be defined and price fluctuations make consumers hesitate and guilty when choosing LED lamps.
Experts pointed out that although the widespread use of LEDs will become an inevitable trend, at present, the products on the market are mixed and the market is not standardized. For consumers, in the face of a lot of jagged products, in addition to comparing prices, there are often doubts and misunderstandings in the mind, so that consumers are discouraged from LED lighting products.
According to industry analysts, the standard is not the only reason for the current situation. What is important is that the detection has not been timely and the power of quality testing has not yet played a role. It is normal for the first LED lighting products to have unqualified products. The key is how to dispose of the unqualified products after the supervision and inspection. It is necessary to have a punishment mechanism to guide, so that the quality of the entire industry can be raised.
