Abstract: A lamp assembly, particularly for an entertainment machine, is made from one or more LEDs soldered to a printed circuit board (pcb). The pcb has an edge region with contacts which is constructed to fit into a lamp holder. The lamp assembly can be used in substitution for a conventional wedge-based push-fit bulb. The pcb edge region may be constructed so that it can only fit one way round in the lamp holder, or the pcb may include circuitry which allows connection either way round (either polarity).

Abstract: A lamp assembly has one or more lamps (8, 9), particularly LED lamps, with terminals (11) attached to a circuit board (10) so as to be supported by the board. The lamp terminals (11) are connected via conductive pathways (12) to edge contacts (A1, A2, A3, B1, B2, B3) on the board which can be inserted into a lamp holder (1) so that the board (10) is supported by the lamp holder (1) and the edge contacts (A1-3, B1-3) conductively engage electrical contacts (5) in the lamp holder (1). The lamp terminals (11) are attached to positions (13) on the pathways (12) on opposite sides of the board (10) so that the lamp (8, 9) straddles the board, preferably symmetrically. Where there are two or more lamps (8, 9) these are connected to different combinations of pathways (12) and edge contacts (A1-3, B1-3) so that they can be operated independently.
