Jinshan City LED light sampling, the failure rate is as high as 90%!

Of the 20 batches of LED lights, 18 were unqualified and the failure rate was as high as 90%! It is understood that the Municipal Industry and Commerce Bureau recently conducted quality inspections on the LED lights sold in Jurong and Dantu markets in the city. The results of the random inspections made people stunned. At present, for the LED lighting products that fail to pass the sampling results, the industrial and commercial departments have ordered the relevant operators to be removed from the shelves and investigated and dealt with them in accordance with relevant laws and regulations.

The Municipal Administration of Industry and Commerce conducted random inspections on LED lamps produced and sold by 11 companies in Hong Kong, Zhongshan, Foshan and other places. They commissioned the Jiangsu Provincial Electric Light Source Product Quality Supervision and Inspection Center to inspect the signs and insulation resistance after moisture treatment. Electrical strength, mechanical strength, power factor, lamp power, initial light efficiency / luminous flux and color rendering index. The sampling results showed that only 20 batches of LED lamps that were sampled were qualified.

According to the relevant person in charge of the Consumer Protection Department of the Municipal Administration for Industry and Commerce, 18 batches of unqualified LED lamp unqualified items are mainly power factor, lamp power, initial light effect/light flux, color rendering index and color product tolerance.

According to the national standard, the color rendering index of self-ballasted LED lamp products for general lighting should be greater than 77. In this sampling, 17 batches did not meet the requirements, and the failure rate was as high as 85%. If the color rendering index is unqualified, the actual reflection value of the object will be insufficient, and the color of the object under the lamp will be different from the color of the real object. The long-term use is harmful to the eyesight of the human eye.

The lamp power is also one of the unqualified items in the sampling of the LED lights. There are 16 batches, and the unqualified rate has reached 80%. The lamp power reflects the energy consumption index of the product, and the power is too large or too small, which reflects that the actual production capacity of the enterprise does not match the design capability.

As an LED luminaire closely related to the lives of ordinary people, the qualified rate of products sold on the market is so low that consumers cannot be relieved. Poor quality LED lamps not only have a short life span, but also have an impact on vision for long-term use. The relevant person in charge of the Consumer Protection Department of the Municipal Administration for Industry and Commerce introduced that the reason for the low qualified rate of LED lamps is mainly because the current self-ballasted LED lamp manufacturers for general lighting are mostly small and medium-sized enterprises, lacking brand awareness, low quality awareness, and some production. Enterprises can't master the content of the standard, lack of inspection methods, and some production companies simplify the production and testing process in order to reduce production costs.

Five points to pay attention to purchase LED lights

At present, the quality of LED lamp products sold on the market is uneven. City Consumers Association reminds consumers to pay attention to the following five points when purchasing LED lights:

1. According to the actual needs and the requirements of the use environment, select the regular brand and the appropriate power LED lights in the regular store, and ask for the formal invoice when purchasing;

2. Ask for the inspection report. The regular LED lamp manufacturers will receive the spot check by the quality supervision and inspection department on a periodic basis. Therefore, the seller should be able to provide the inspection report of the quality inspection department and the energy efficiency report of the product;

3. Check the product packaging and logo. When purchasing, please check whether the product trademark, factory name, actual model, specification, power, rated voltage, rated power and other signs are complete. Check whether there is a “CQC” or “energy-saving certification” mark on the package. If the company obtains the “CQC” or “energy-saving certification” mark, it proves that the product quality of the enterprise is more secure than the general qualified product.

4, to view the appearance of the product, the formal LED lamp manufacturers pay great attention to the technical details of the product, when buying, pay attention to whether the appearance of the product is rough, whether the joints and transitions are handled without flaws;

5, lighting LED light detection, consumers need to carefully observe the color change of the LED light after lighting, the color of the LED light must be positive, the color of the light is consistent, not flashing, after lighting, you can also touch the surface temperature detection light of the product In the case of heat dissipation, if the surface temperature of the product continues to rise within 1 hour, it is best not to choose this product, because poor heat dissipation will lead to shortened product life.
