Zusammenfassung:	The lighting apparatus includes a LED module, a constant current source, a bridge rectifier, a silicon-controlled rectifier, a wireless module and a detector. The lighting apparatus receives an alternating current power to generate a light. The constant current source provides a driving current to the LED module. The bridge rectifier converts the alternating current power of a first frequency to a direct current power with a second frequency. The second frequency is two times of the first frequency. The silicon-controlled rectifier is connected to the alternating current power and the bridge rectifier for adjusting the direct current power with a chopping signal. The wireless module receives an external control signal. The detector generates a dimming control signal supplied to the constant current source to adjust the driving current according to both the external control signal and the chopping signal.
