Abstract
A lighting apparatus includes a constant current generator, a voltage converter and a PWM generator. The constant current generator for generating a driving current. The current level is determined according to a dimmer signal received from the dimmer. The voltage converter converts the current level of the driving current to a voltage level. The PWM generator generates multiple PWM signals respectively to multiple LED modules. The multiple LED modules have different optical parameters. The mixed light of the multiple LED modules is determined by the PWM signals and the optical parameters of the multiple LED modules.
