1. The method for adjusting the wave band of the color temperature spectrum simulator based on the synthesis principle of a plurality of narrow-band wave bands is characterized by comprising the following steps of:

by adjusting the inclination angle between the band-pass filter of the band light intensity controllable unit of the color temperature spectrum simulator and incident light, the narrow-band light band output with the center wavelength and the bandwidth capable of being finely adjusted can be obtained by utilizing the phenomenon that the center wavelength of the peak value of the narrow-band filter moves towards the short-wave direction and the bandwidth expands when the narrow-band filter obliquely enters, and meanwhile, the power of the band light intensity controllable unit is adjusted to make up the loss increase caused by oblique incidence.

2. The method for adjusting the wavelength band of a color temperature spectrum simulator based on the synthesis principle of a plurality of narrow band bands according to claim 1, which comprises the following steps:

step S1: the band light intensity controllable units of the band-pass filters with corresponding nominal peak center wavelengths and bandwidths respectively output narrow-band light components with certain power according to the color temperature spectrum simulation requirement, and the designed simulated spectrum output can be obtained after the convergence and the dodging treatment;

step S2: when the narrow-band light components are output, if the junction of the two narrow-band light components has an out-of-tolerance recess, adjusting the inclination angle of the optical filter with a longer nominal center wavelength, and simultaneously adjusting the power of the light intensity controllable unit of the waveband to make up for the loss increase caused by oblique incidence, so that the output narrow-band light components are wholly translated towards the short wavelength direction, and the out-of-tolerance recess at the junction is filled;

step S3: if a new out-of-tolerance notch occurs in step S2, the above step S2 is repeated to obtain the best simulated spectral output.
