A lighting apparatus includes a light source, a silicon controlled rectifier, a rectifier and a current source circuit. The light source has multiple LED modules with different light parameters. The silicon controlled rectifier filters a filtering ratio of an input AC power to a filtered AC power. The filtering ratio is associated with a control angle by supplying a control voltage to the silicon controlled rectifier. The maintainer circuit maintains a working current to the silicon controlled rectifier even when the control angle is large causing the volume of the filtered AC power less than a threshold. The current source circuit receives the DC power. The current source circuit has a wall switch input for connecting to a wall switch. An on-off input pattern of the wall switch is detected by the current source circuit for generating multiple corresponding driving currents.
