Experimental research on heat dissipation characteristics and power-heat conversion monitoring model of lightings in public build

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.
