    • The invention discloses a method of constructing light-measuring look-up table, a light-measuring method, and a light-measuring system. The method of constructing light-measuring look-up table is to construct a look-up table by according to spectrum parameters relative to a light spectrum model, three actual color-matching functions relative to the light-measuring system and three standard color-matching functions, calculating both a look-up color coordinate and a reference color coordinate corresponding to each of the spectrum parameters. The light-measuring method includes: first, measuring a to-be-measured light by the light-measuring system to obtain actual stimulus values and calculating an actual color coordinate; then, comparing the actual color coordinate with the look-up color coordinates to determine both a to-be-measured light spectrum parameter and an estimated color coordinate relative to the to-be-measured light; furthermore, according to the to-be-measured light spectrum parameter, one of the standard color-matching functions and one of the actual stimulus values, calculating an estimated luminance.
