description A lighting apparatus includes a light source plate, LED modules and a driver module. The light source plate includes a substrate layer, a wiring layer and a protection layer. The substrate layer is made of metal material. LED modules are disposed on a top side of the light source plate. The driver module is disposed on the top side of the light source plate. The LED modules and the driver module are electrically connected via the wiring layer. The driver module includes an AC-DC converter, a regulator, a controller, a current source and an oscillation wave removal circuit. The controller controls the current source to generate driving currents to the LED modules. The oscillation wave removal circuit is coupled to the AC-DC converter for suppressing a sudden abnormal peak voltage from the AC-DC converter.
