Abstract
A lighting apparatus includes a first LED module, a second LED module, a rectifier, a power circuit, a time detector, a wall switch circuit and a controller. The first LED module has a first light parameter. The second LED module has a second light parameter. The first light parameter is different from the second light parameter. The power circuit converts the DC power to a first driving current and a second driving current respectively supplied to the first LED module and the second LED module. The time detector detects a voltage time variation of the DC power. The controller is coupled to the wall switch circuit and the time detector for determining whether to adjust a current ratio between the first driving current and the second driving current according both the voltage time variation and the control signal.
