Lighting apparatus

Abstract

The lighting apparatus includes a first LED module, a second LED module and a third LED module. The first LED module emits a first light of a first color temperature. The second LED module emits a second light of a second color temperature. The third LED module emits a third light of a third color temperature. The driver is used for generating a first driving power, a second driving power and a third driving power respectively supplying to the first LED module, the second LED module and the third LED module. The controller is for determining a power ratio corresponding to a mixed light with a target color temperature mixed by the first light, the second light and the third light. The mixed lights of different target color temperatures have chroma coordinates within a predetermined chroma range.
