LED lighting product quality worrying

In the development of LED lighting in recent years, confusion, standards ambiguity, lack of talent, price wars, quality gates, running routes, and failures are all synonymous with the status quo of the LED industry. The state gives it great policy support, but it is currently During the reshuffle, the LED industry is still in deep water. Recently, various provinces and cities have made quality inspections on LED products. Among the supervision and inspection results issued by the Guangdong Provincial Bureau of Quality Supervision, nearly 40% of LED street lighting companies failed spot checks, including 51 batches of LED street lamps and light source controllers. The spot check found that 20 batches were unqualified, and the discovery rate of unqualified products was as high as 39.2%. Among the unqualified companies, some companies are listed companies and have won many green awards in the past two years. From this point of view, the quality of LED lighting products is worrying in this “unresearchable” industry.

The problem of quality inspection was presented in spot checks of unqualified LED street lamps and light source controllers. The 20 batches of products did not meet the requirements of the standard, involving structure, grounding regulations, external wiring and internal wiring, dust and waterproof, insulation resistance and electrical Strength, heat resistance, fire resistance and tracking resistance, power terminal disturbance voltage, radiated electromagnetic disturbance (30MHz-300MHz), harmonic current emission, surge immunity, electrical performance of the lamps, protection class, average color rendering index, light distribution Curves and other items. Dust and waterproof are more unqualified, involving 6 batches, external wiring and internal wiring unqualified, involving 7 batches.

The quality of LED lighting products is irritating and the quality inspection results of the related quality supervision departments showed that the LED lighting industry's quality qualification rate is not satisfactory. In some places, the passing rate of energy-saving lamps is even less than 20%. This year's recent spot checks of lighting products are equally unsatisfactory. In Chengdu, 50% of the street lamps failed. Sixty percent of Jiangxi's emergency lights failed. The quality of the lamps and lanterns in Hunan Quality Supervision Department was spot-tested and failed to pass the inspection. We also often see the news that LED blind lights cause eye blindness and street light chandeliers hurt the quality of LED ceiling lamps. Product quality problems have always been a headache issue for the LED lighting industry.

Some merchants and enterprises slammed and accused Accessories companies of cutting corners and materials, resulting in lighting products in the pressure, high temperature, flame retardant and other aspects do not meet the production requirements, quality is not qualified, and accessories companies are also bitter to say: "I also We do not want to do waste products. If it is not for finished products, we do not need to do so." Who should be responsible for consumers?

LED listed companies are also trapped in the quality of Lehman quality lawsuit as one of the few well-known companies listed in the LED industry, and recently because of its contract customers exposed to the media due to the defects of their products led to a large number of dead lights LED screen into a dispute. After the incident, Lehman Optoelectronics quickly responded to this, and the company never shied away from any product quality problems. As long as the company was clear about quality responsibility, it had never evaded or pushed any of its customers' quality responsibilities.

Zhou Ming Science and Technology Quality Supervision was not qualified. In the Guangdong Province quality supervision and inspection, Zhong Zhou Technology was also found to be unsuccessful. However, it was later approved by the Bureau of Quality Supervision, and was qualified for inspection after rectification, but this also gave This "green product" company called the listed company to bring a touch of gray.

After seeing the quality door issues of the two listed LED companies, let us consumers feel a bit dazed and questioned. Under the banner of promoting LED lighting products, do we see just these disappointing news? The rights and interests of consumers also need to be valued and thought-provoking by companies that have failed to meet these quality standards.
