Claim of US Patent No. 10,317,016

1. A lighting device comprising a housing, a light engine located in the housing with a printed circuit board (PCB) and one or more light emitting diodes (LEDs) arranged on the PCB, and an electronic driver for controlling the LEDs, wherein the electronic driver comprises a first driver part located at a first position in the housing and a second driver part located at a second position in the housing, the first driver part and the second driver part being electrically connected to each other via a pair of electrically conductive traces on the PCB, characterized in that the lighting device further comprises one or more capacitive devices arranged along the pair of electrically conductive traces connecting the first driver part and the second driver part, wherein each capacitive device is connected with a first terminal to a first trace of the pair of electrical traces and with a second terminal to a second trace of the pair of electrical traces such that each capacitive device is configured to reduce electromagnetic interference (EMI) generated by the lighting device during operation.
