The invention discloses an LED standard light source color matching device, which comprises a quantum dot LED lamp, a detector with optical photography, a microprocessor and a memory. The microprocessor is connected with the quantum dot LED lamp, the detector with optical photography and the memory; the memory stores optical parameters of the quantum dot LED lamp, and the optical parameters including one or more selected from a color rendering index value, a panchromatic gamut index value, spectral energy distribution, brightness, uniformity, color temperature, light color quality and color tolerance form a standard light source parameter scene; and an optical data adjustment control program is arranged in the microprocessor, and the program can be used to automatically or manually triggerand call the standard light source parameter scene matching a target product in the memory according to the target product which needs color comparison by the detector, so as to adjust an electric light source of the quantum dot LED lamp. Color matching errors are reduced, and the situation that electric light source needs to be replaced to realize control for different color temperature is avoided.
