Experimental research on heat dissipation characteristics and power-heat conversion monitoring model of lightings in public build
摘要：
针对照明灯具散热特性及散热量监测计算问题，根据试验测试需要建立了绝热方舱试验系统，研究了典型灯具在绝热方舱中的散热特性。典型照明灯具总散热量与电功率的比值为0.72～0.77，与灯具类型、额定功率相关性不大。根据试验数据和最小二乘法原理，建立了照明灯具的功热转换监测模型。在利用各类型、各额定功率灯具试验数据验证过程中，灯具总散热量功热转换监测模型的平均绝对百分比误差（MAPE）和平均绝对误差（MAE）分别不超过7.62%和3.52 W。
Abstract：
Aiming at the problems of the heat dissipation characteristics of lightings and monitoring and calculating of their heat dissipation, an adiabatic experimental chamber is established according to the needs of test, and the heat dissipation characteristics of typical lightings in adiabatic experimental chamber are studied. The ratio of total heat dissipation to electric power of typical lightings is 0.72 to 0.77, which is not related to the type and rated power of lightings. The power-heat conversion monitoring model of lightings is developed based on the experimental data and the least square method. The experimental data of lightings with different types and rated powers are adopted in the verification process, and the value of mean absolute percentage error (MAPE) and mean absolute error (MAE) of the power-heat conversion monitoring model of the total heat dissipation are less than 7.62% and 3.52 W, respectively.
