Abstract
A lighting apparatus includes a bridge circuit, a current source, a first LED module, a second LED module and a switch. The bridge circuit is used for rectifying an input AC power to generate a DC power. The current source receives the DC power to generate a driving current. 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 switch is coupled to the current source to change at least a resistance parameter corresponding to a current ratio between the first LED module and the second LED module to generate a mixed light of a mixed color temperature.
