Removable luminaires are a widely used lighting product in residential luminaires. The purpose is to provide a level of illumination that is significantly higher than the surrounding area of ​​the work area for reading, writing, drawing or work area lighting in the computer screen area. Recently, Tianjin Quality Supervision Bureau conducted supervision and random inspection on 20 batches of movable lamps produced by 18 enterprises in Guangdong, Liaoning and other provinces and cities. The results of random inspections, 7 batches qualified, 13 batches failed, sampling The pass rate is only 35%.
The main problems found in the spot check are: internal and external wiring, heat resistance, fire resistance, structure, protection against electric shock, dust, and solid foreign objects are not up to standard.
According to reports, the national standard stipulates that the external wiring cross-sectional area of ​​the luminaire should be ≥0.75mm2, and the internal wiring cross-sectional area should be ≥0.4mm2. Too small cross-sectional area of ​​the conductor is a major safety hazard of the luminaire. Once a fault occurs and a large current is generated, the conductor is easily burned, causing a fire or electric shock and other safety accidents. This batch of inspections has 12 batches of products that are unqualified. Insulation materials used in 3 batches of goods do not meet the requirements for heat resistance and combustion resistance. There are 3 batches of products with rough processing technology, acute corners or burrs at the internal wiring. During the process of use, the internal conductor insulation layer is easily pierced, and there are safety hazards such as short circuit and electric shock. There are 1 batch of products that are protected against electric shock and dust and solid foreign materials are unqualified, which may cause accidents during the use and adjustment of the lamps.
The products with poor quality of this spot check are: sold by the Nanfang Lighting Post Lighting Business Department of Tianjin, which is called “Shangmei†brand 5638 table lamp produced by Shangmei Lighting & Electric Appliance Factory of Xiaolan Town, Zhongshan City. Its marking, structure and interior The external wiring is unqualified; the “Lelis†brand MT type lamp produced by Zhongshan Guzhen Baihua Lighting Factory, which is sold by Hancheng Bridge Decoration City Hengfeng Lighting, is unqualified for its marking, structure and internal and external wiring. ; "Daobaoda" brand GD-3033 energy-saving table lamp produced by Foshan Shunde Guandi Electric Industrial Co., Ltd., marked, internal and external wiring, anti-distribution The electric shock protection is unqualified.
