Claim Text:
1. A driving method of a light-emitting module, comprising: disposing P light-emitting units corresponding to different emission spectra so as to constitute a target group, each of the light-emitting units corresponding to N power parameters in respectively N frequency sub-bands, the light-emitting module comprising the target group; computing P evaluated current values corresponding to the P light-emitting units according to a target spectrum and the N×P power parameters corresponding to the P light-emitting units, the target spectrum having N target-spectrum values in the N frequency sub-bands; computing an emission-spectrum error according to the target spectrum, the N×P power parameters and the P evaluated current values corresponding to the target group; determining whether the emission-spectrum error conforms with a criterion; and setting the P evaluated current values as P driving current values corresponding to the P light-emitting units when the emission-spectrum error conforms with the criterion; wherein P and N are positive integers.
