摘要： A lighting apparatus includes a first light source, a second light source and a driver. The first light source has multiple first LED modules. The second light source has multiple second LED modules. The driver controls the first light source and the second light source to generate an output light of a required mixed color temperature. The driver selects a first subset of the multiple first LED modules and a second subset of the multiple second LED modules to generate a first output light with a first color temperature. The driver selects a third subset of the multiple first LED modules and a fourth subset of the multiple second LED modules to generate a second output light with a second color temperature. The first subset is not equal to the third subset. The second subset is not equal to the fourth subset.
