A lighting device comprising a housing (102) with a driver electronics module (104) including driver circuitry for driving light sources and an electronics connector (106). The lighting device further comprising a circuit board (108) arranged in the housing, including a board connector (110). Furthermore lighting device comprises at least one light source (109) arranged on the circuit board and being in connection with the board connector, wherein the electronics connector and the board connector extend transverse to a planar extension of the circuit board. The board connector and the electronics connector are aligned so that they have an area of overlap, wherein the board connector and the electronics connector are biased against each other such that there is at least a line of contact which provides a galvanic connection, and wherein a heat induced electrical interconnection is provided along the line of contact. Such a connection is time- and cost efficient to assemble compared to a wire connection.
