Zusammenfassung:This disclosed embodiment relates to a power drive circuit arrangement and includes: power input holds (L), coupling to power source, with circuit board (10) of power input end coupling, it is uploaded and puts the power switch (U2) that is used for the storage to come from the power inductance (L3) of the power of power source and be used for the break -make of control load main circuit, and spatial filtering component (F1), can absorb the electromagnetic radiation who propagates in the space among the power drive circuit arrangement, the coupling is between power input end and circuit board to be configured as and separate the certain distance with the circuit board and arrange. This disclosed embodiment still relates to a lighting apparatus. According to the power drive circuit arrangement and lighting apparatus of this disclosed embodiment, the electromagnetic radiation that electrical component sent of spatial filtering component on can the snubber circuit board gets back to the power input end, reduces
