Anhui lamps and lamps product sampling results: four enterprises boarded black list"

The day before, the Anhui Provincial Quality Supervision Bureau of the lamps and lighting products of the provincial supervision within the province to carry out, specific information is as follows:

A sampling survey

In the sample of 6 areas of Anhui province from 19 samples, among them, 11 in Hefei group, Mount Huangshan group 2, Lu'an area 2 group, 2 group in Wuhu area, Tongling area, Bozhou area 1 groups, 1 groups were selected from the production enterprises. The results were as follows: 15 qualified groups, the total pass rate of 79%, unqualified group, the failure rate was 21%, the rate was 4.

Sub regional perspective, the 10 groups of samples in Hefei qualified, unqualified in the 1 groups, the pass rate of 90.9%. The 1 groups of samples in Mount Huangshan area were qualified, and the qualified rate was 50% in the 1 groups. The 1 groups of samples in Lu'an area were qualified, and the qualified rate was 50% in the 1 groups. The qualified rate of 2 groups in Wuhu area was 100%. Tongling a group of unqualified, qualified rate of 0. Bozhou qualified rate was 100%.

Two, quality analysis

The inspection is based on the inspection of lamps and lighting products provincial supervision and sampling rules. (the basis for the formulation of the rules: (GB16844-2008, GB7000.5-2005, GB7000.203-2013, GB7000.1-2007, GB17625.1-2012, GB7000.201-2008, GB7000.202-2008, GB19044-2013, GB/T17263-2002, GB/T17263-2013) and the relevant requirements of the national standard, sign of lights and lighting products (safety), to prevent electric shock, mechanical strength, lamp power, initial luminous flux, / the color index, and harmonic structure, external wiring, internal wiring, electric shock protection, insulation resistance and electric strength, leakage current, harmonic current and other technical indicators to carry out inspection work.

Test results show that the province's overall pass rate improved lighting products. At the same time, there are quality problems in individual products:

(a) the main problems found in the survey are as follows:

1 signs: in this spot checks of the 2 groups of ordinary lighting from the town of fluorescent lamps in the presence of the 1 groups marked items failed. The main problem is that the manufacturer does not provide additional information on the lamp, or on the package, or in the instruction manual - the lamp current.

2 lamp power: in the spot checks of the 2 groups of general lighting with self ballasted fluorescent lamps in the presence of the 1 groups of lamp power project failure. The main problem is that the actual power consumption of the lamp is beyond the range of the rated power. Lamp power refers to the normal operation of the active power consumption, some enterprises in order to improve the price will tend to increase the power of small power lamp, with a larger difference between the rated power, deception and harm the interests of consumers.

3 the initial luminous efficiency / luminous flux: in this sample of the 2 groups of general lighting from the ballast fluorescent lamps are the initial luminous efficiency or luminous flux project failure. The main problem is the manufacturer claimed to be equivalent to a certain specification of incandescent lamp, but its luminous flux does not meet the GB/T17623-2013 standard value, or the light effect does not comply with the GB/T17623-2013 standard value. The use of three color phosphor energy-saving lighting effect and long service life, but some cheap energy-saving lamps with halogen lamp powder, light effect can not be reached, energy-saving effect, short service life, consumers use this kind of energy-saving lamp lamp change because often lead to increased costs, saving money is not low rise purchase cost. From the results of energy saving is to save money.

4 harmonic current: in this spot checks of the 2 groups of general lighting with self ballasted fluorescent lamps in the presence of the 1 groups of harmonic project failure. The main problem is that the harmonic limit value of lamp is not up to the standard of GB 17625.1-2012. If the harmonic standards, will produce the following hazards: first, causing the cable overheating; second, cause transformer overheating; third, resulting in reactive power compensation device is damaged; fourth, resulting in additional energy loss; fifth, lead to unexpected trip; sixth, to other electronic equipment produces negative effects.

5 Structure: there are 1 groups of other lamps and lanterns in the sample of the existing structure of the sample is not qualified in the 17 groups. The main problem is that the power terminal does not take the positioning or protective measures. When the installation is completed, there are short circuit, electric shock and other security risks.

6 internal wiring: in this sample of the 17 groups of other lamps and lanterns in the sample there are 2 groups of internal wiring failure. The main problem is that the end of the soft wire is too much tin plating, and no measures to ensure that when the cold deformation of the solder joints are not loose. In the use of lamps, there are open circuit, poor contact and other hidden dangers.

(two) for the provincial spot checks, the main reasons for the poor quality of lamps and lighting products may have the following points:

1, the increasingly fierce market competition, some businesses to reduce prices to compete for the market, seeking sales, resulting in some low price, poor quality products into the market;

2, the low level of specialization of production enterprises, the lack of professional knowledge and technical personnel with a certain lamp, the relevant technical staff of the lamp is not enough understanding of the standard, the lack of standards related to the training of lamps and lanterns. For example, the internal structure of the soft end of the wire strand is not qualified, if the technical staff to understand the lamp standards, is very easy to improve;

3, some enterprises may be affected by the lack of funds or restrictions on the scale of lights and lighting necessary professional testing equipment, products manufactured before no important parameters for inspection, and not to the professional testing organizations test qualified, resulting in unqualified products;

4, the product production process is not strictly in accordance with the requirements of the process documents, the production process in the quality control of individual links, resulting in substandard products factory.
