ABSTRACT:
In a lighting-fitting comprising a socket-structure for an electrical lamp and a filter device to remove smoke components of cigars and cigarettes, which device is provided with an electrical blower (6) and at least one smoke filter (3,4), the socket-structure is housed within a first hood (1), which is placed within a larger second hood (2), such that a space between the first hood and second hood forming a smoke channel (7, 7') extending to the filter device is defined. Furthermore, the socket-structure is designed for at least one TL-tube, while the smoke filters (3,4) are located within the second hood (2) over the top of the first hood (1), and the first hood (1) can easily be assembled and disassembled relative to the second hood (2). In a preferred embodiment, the space between the first hood (1) and the second hood (2) defines an exhaust channel (12) extending from the filter device, to exhaust filtered air. Furthermore, the feeding openings (8, 8') and the exhaust openings (13 ) of the smoke channel (7, 7') at the exhaust channel (12) respectively extend in lengthwise direction on both sides of the first hood (1). The feeding openings (8, 8') and the exhaust openings (13) can be defined by a slit with varying width between the first hood (1) and the second hood (2). To easily assemble and disassemble the first hood (1) relative to the second hood (2), the first (1) can be pivotably mounted within the second hood (2).
