The spectral distribution of infrared lamp which used in thermal vacuum test of spacecraft is studied. By correlation analysis and data fitness of Current-Voltage relationship of infrared lamp, power Model for infrared lamp is established. Based on it, the filament temperature calculation model of infrared lamp is built, and the quartz glass tube temperature calculation model of infrared lamp is also built. Spectral pattern model of infrared lamp is established finally. Spectral pattern of infrared lamp is measured by applying the S2000 type of optical Fiber spectrometer, results show that Spectral Pattern model of Infrared Lamp is correct. The paper's result can lay a foundation for measuring of infrared lamp array arriving heat flux with adiabatic heat flux sensor.
