Abstract
A lighting apparatus includes a driver, a metal plate, a light source module and a conductor unit. The driver receives an alternating current power source and converts the alternating current power source to a driving current. The metal plate is electrically connected to a ground. The light source module has a substrate and multiple LED modules. The multiple LED modules are mounted on the substrate. The substrate is disposed upon the metal plate. The conductor unit has a first end connected to the substrate of the light source module and a second end connected to the metal plate for removing a parasitic capacitance between the substrate of the light source and the metal plate for preventing a noise occurred when the LED module is turned on and the metal plate is connected to the ground.
