The Trade and Industry Bureau of Jilin Province entrusted the Songyuan City Administration for Industry and Commerce to spot-check and test LED lamps produced and sold by 14 companies including Zhongshan, Foshan and Jiangmen. This product quality inspection is based on GB/T24908-2010 "performance requirements for self-ballasted LED lamps for general lighting", GB24906-2010 "security requirements for self-ballasted LED lamps above 50V for general lighting" and the country or industry identified by the product. standard. Key indicators such as identification, lamp power, initial light efficiency, power factor, color characteristics, and dielectric strength were examined. Among the 20 samples, 19 samples were judged to be unqualified, and the failure rate was 95% (Inspection of commodity quality by the industrial and commercial department) Has a certain degree of specificity, the test results do not represent the overall quality level of the market circulation of goods). The main problems are:
First, the mark failed. The rated current of the product is not marked. The rated current of electrical equipment refers to the allowable current when the electrical equipment is continuously operated for a long period of time under the rated environmental conditions (ambient temperature, sunshine, altitude, installation conditions, etc.), and the current should not exceed its rated current when the appliance is used, otherwise it is possible. There are dangers such as fever and burning. In the spot check, 6 samples failed the project, accounting for 30% of the total number of unqualified.
Second, the lamp power is not qualified. The lamp power refers to the effective power consumed during normal work and reflects the energy consumption index of the product. Some companies increase the logo power of small power lamps in order to increase the selling price, and have a large difference from the rated power, thus deceiving consumers. In the spot check, 6 samples failed the project, accounting for 30% of the total number of unqualified.
Third, the initial light efficiency, the initial luminous flux failed. In order to reduce costs, some companies use ordinary calcium phosphate powder instead of high-efficiency three-color phosphors, so that the luminous flux does not meet the standards. The brightness is OK when the user first uses it, but it will soon be dark and the lifespan is short. In the spot check, one set of samples failed the project, accounting for 5% of the total number of unqualified.
Fourth, the color characteristics failed. The color characteristics are an important indicator of the energy-saving lighting parameters. From these indicators, it can be seen that the purity of the three-color phosphors used by the manufacturer, processing technology and technical level. In the spot check, 12 samples failed the project, accounting for 60% of the unqualified total.
Fifth, the dielectric strength failed. Flashover (flashover) or breakdown in the dielectric strength test. Poor quality insulation material may be used or breakdown may be caused by insufficient clearances and creepage distances, posing a safety hazard to users' lives and property. . In the spot check, 6 samples failed the project, accounting for 30% of the total number of unqualified.
In light of the unsatisfactory results of LED lamps and lanterns with sample inspection results, the industry and commerce departments have ordered the relevant operators to lower the cabinets and investigate and deal with them in accordance with relevant laws and regulations. Here, to remind consumers in the purchase of LED lighting products should pay attention to the following points:
1. Look at product packaging and trademarks
This is the simplest and most intuitive method of identification. The packaging of genuine LED lamps should be marked with the rated voltage, voltage range, rated power and other information, as well as brand trademarks and related certification marks. The trademark of the genuine LED lamp on the outer package has better printing quality, the font is clear, and it is not easy to fall off. That is, it is wiped with a soft and damp cloth, and the trademark is still legible. The poor quality of the trademark of the shoddy products is poor, the fonts are fuzzy, and the trademarks of some products can be wiped with a damp cloth. In addition, there are no printed trademarks and related certification marks on the packaging of some inferior products.
