A semiconductor device comprising a support (1) provided with a groove (2) having walls (3 and 4), on which conductors (6 and 7) are present, which conductors extend at least partially around the support (1), and with a semiconductor element (11) which is present in the groove and makes electrical contact with the conductors on the walls. The semiconductor element (11) is clamped in the groove (2), thus making electrical contact with conductors (6 and 7) on walls (3 and 4). Since the semiconductor element (11) is held clamped-in between the conductors (6 and 7) on the walls (3 and 4), it is achieved that both a mechanical and an electrical connection is realized between semiconductor element (11) and support (1) in a single process step and in a simple manner.

Semiconductor device having a clamping support

Luminaire for a tubular discharge lamp, having an elongate housing (1) the ends of which comprise means (4, 5) for accommodating the lamp, at least an electric ballast (6) being present in the housing (1), which housing is filled with cured foamed plastics material (11), the housing (1) being a through with a generally U-shaped cross-section and the foam (11) extending to the open side of the housing.
