In the third quarter of 2008, the Shanghai Municipal Bureau of Quality and Technical Supervision conducted a special supervision and spot check on the quality of embedded lighting products produced and sold in Shanghai.
Of the 22 batches of the spot checks, 19 were embedded incandescent lamps without dimmer switches, and 3 were embedded gas discharge lamps with control devices. After testing, it was judged that 9 batches were qualified, and 13 batches were unqualified (one batch was serious quality problem), and the sampling pass rate was 40.9%. From the inspection results, the main unqualified items are marking, internal wiring (cross-sectional area), heat resistance and fire resistance.
There are 13 batches of luminaires that fail to be identified. The most prominent problem is the incomplete markings on the luminaires and the improper marking position. The marking of the luminaire, including the markings on the luminaire and the additional content that can be given in the instructions provided with the luminaire, is an important safety indicator for the installation, use and maintenance of the product, including the rated power, rated voltage and minimum of the object being illuminated. The symbol of the distance, etc. According to the relevant regulations, the information related to the light source such as the rated power should be marked on the outer surface of the luminaire, or the reverse side of the cover that is removed when changing the light source to ensure that the light source information can be seen when the light source is changed. The information related to the light source, such as the rated power, cannot be marked on the mounting surface that is not visible when the light source is changed. It is not properly marked. There are 11 batches of the 13 batches of unqualified products that have been rejected due to the above problems.
The internal wiring (cross-sectional area), heat-resistance and fire-resistance items are the main items for the unqualified quality of this sample. The standard stipulates that the cross-sectional area of ​​the internal wiring of the luminaire shall not be less than 0.5mm2 without the prescribed protective measures. If the cross-sectional area of ​​the wire is too small, it is a major safety hazard. If a large current occurs during the fault, the insulation of the wire may be burned before the operation of the power supply bypass system, which may cause a fire or electric shock. The insulating materials used in lamps or components shall be heat-resistant and fire-resistant so that the lamps will not be unsafe due to deformation or ignition of the insulating materials during normal operation.
It is reported that the Shanghai Municipal Quality Supervision Bureau has requested the relevant district and county quality and technical supervision departments to strictly handle the unqualified products in the spot checks in accordance with the relevant laws and regulations, and rectify within a time limit. The bureau will also organize law enforcement personnel to supervise and inspect the handling of unqualified products of relevant enterprises, and seriously deal with enterprises that continue to sell unqualified products in accordance with the law to ensure the safety of the personal and property of consumers.
