摘　　要：当家庭电路中接入的用电器超出了线路的承载能力,长期超负荷运行将导致发热量剧增,加速绝缘层的老化。在温度升至250℃以上时,绝缘层可能自燃并从电线上脱落,引发短路甚至火灾事故。因此,无论是家用电器还是LED模块,对功率限值都有严格的规定。本文依据GB/T 9473—2022《读写作业台灯性能要求》标准,对功率要求进行了深入探讨,通过对多款不同功能台灯产品的测试,分析了标准中对实测功率的测试要求,并提出了关于读写作业台灯产品功率测试状态的建议。这些建议对于检验检测人员和灯具制造商在确保产品符合安全标准方面具有重要的参考价值。When the electrical appliances connected to the household circuit exceed the carrying capacity of the circuit,long-term overload operation will lead to a significant increase in heat generation,accelerating the aging of the insulation layer.When the temperature rises above 250℃,the insulation layer may self ignite and detach from the wire,causing short circuits and even fire accidents.Therefore,both household appliances and LED modules have strict regulations on power limits.This article explores the power requirements in depth based on the GB/T 9473—2022 Performance Requirements for Reading and Writing Desk Lamps.Through testing multiple different functional desk lamp products,the article analyzes the testing requirements for measured power in the standard and proposes suggestions for the power testing status of reading and writing desk lamp products.These suggestions have important reference value for inspection and testing personnel and lamp manufacturers to ensure that products comply with safety standards.
