Definitions

  • the invention relates to a luminaire with a housing made of an elongated part and end parts for receiving a rod-shaped or tubular lamp, in which the underside of the elongated part facing the lamp is formed as a trough-shaped reflector, which runs parallel to the lamp and against it The apex has a lowered edge.
  • Such a lamp is known, for example, from DE-A-2903993, in which the surface of the housing facing the fluorescent lamp is shaped in a reflector-like manner such that it is angular in the central region
  • the invention is therefore based on the object of proposing a luminaire in which dust deposits on rod-shaped or tubular lamps are prevented or greatly reduced.
  • the reflector in the case of a luminaire of the type mentioned at the outset, the reflector consists of two concave surfaces parallel to one another and to the lamp there is that the lowered connecting edge between the two surfaces runs in the immediate vicinity of the lamp, that the concave surfaces have a constantly increasing radius from the inside out and that the Ob reflector together with the end parts defines a narrow space that is closed laterally and upwards .
  • Air flow which rises on and above the lamp and falls down along the reflector, and on the one hand causes no dust to deposit on the lamp and on the other hand the lamp is cooled, which leads to a
  • the housing has end pieces which are provided with means for joining several housings in parallel and also for hanging the housings on special connecting elements, for triangular or polygonal or star-shaped arrangements of individual lights or of 25 parallel groups of multiple lights in a simple way.
  • 35 shows a side view of an embodiment of the lamp according to the invention.
  • Fig. 2 is a plan view of the lamp of Fig. 1; 3 shows a section along the line AA in FIG. 1 on an enlarged scale;
  • Fig. 5 shows a parallel arrangement of three lights
  • FIG. 7a shows an arrangement of two groups of three according to FIG. 6 in a diamond shape
  • FIG. 7b shows an assembly type of the arrangement according to FIG. 7a
  • FIG. 9 shows an arrangement of two groups of three similar to FIG. 8 in a diamond shape
  • FIG. 10 shows a large field arrangement with three groups of three according to FIG. 6;
  • FIG. 11 shows a large field arrangement with three groups of three b according to FIG. 7;
  • the housing 1 shown in FIG. 1 from the side consists of two end pieces 2 and an elongated stretched middle piece 3.
  • the end pieces 2 are described in more detail below with reference to FIG. 4.
  • the center piece 3 also represents the reflector, which is described in detail in connection with FIG. 3.
  • Above the Ob middle piece 3 is a box in which the
  • Ballast and the electrical connections are arranged.
  • a grid 5 known per se is arranged on the underside of the housing 1.
  • the central part of the housing has an edge 6 along its central axis.
  • the spinal ⁇ part 3 consists of an elongated sheet metal profile, which has the shape of two mutually parallel elongated channels. In the middle, these two channels meet in an edge 6 which projects inwards.
  • the radius of the concave cross section increases continuously from the edge to the outside in such a way that a beam directed outwards from the central axis of the tube 7 does not strike the inside of the central part 3 perpendicularly at any point. Since, as already mentioned, the 2b inside of the middle part 3 serves as a reflector, this fact means that no rays from the lamp 7 are reflected back into the latter, but rather reach the outside in full.
  • the lamp 7 is arranged in the trough formed by the middle part 6 in such a way that it leaves only a small gap between itself and the edge 6.
  • the gap width is preferably less than 5 mm. This narrow gap ensures an optimal flow of warm air to prevent
  • the shape of the end part 2 can also be seen.
  • the side edges of the end part are not perpendicular to Upper or lower edge, but form an angle of approximately 7-15 ° with them.
  • FIG. 4 an end part 2 is shown in an enlarged view Ob.
  • the end part 2 has side tabs which are used for connection to the middle part 3, for example by spot welding.
  • the side tabs are inclined by the aforementioned angle of 10 approx. 7-15 ° with respect to the lower edge.
  • the end part also has an upper horizontal tab which, as shown in FIG. 2, has a triangular shape and is provided with a bore. This upper tab is used for direct fixation or for hanging the housing on 1b suitable connecting elements, as can be seen from FIGS. 6ff.
  • the housing consists of a closed box in which the reflector is mounted.
  • the box is preferably made of reinforced plastic.
  • FIG. 6 shows an arrangement of three individual lights 11, 0 12, 13, which are connected to one another with connecting elements 14, 15, 16. The entire group can be attached very easily by hanging the connecting elements 14 to 16, ie by three suspension points.
  • This luminaire arrangement in the equilateral triangle b is particularly advantageous for illuminating a room.
  • the incidence of light from different directions and the different illuminance levels with triple, double or single intensity result in an increased plasticity compared to conventional row arrangements of lights.
  • FIG. 7a shows the connection of two lamp arrangements connected to form triangles to form a diamond shape.
  • the triangles are connected to one another at a certain angle along the usual diagonal, which is created by the touching triangle sides. In this way, the assembly can be carried out with the diagonal lowered relative to the corners (FIG. 7b).
  • FIGS. 10 and 11 consist of three equilateral groups of three 23, 24, 25 according to 30 FIG. 6 and 27, 28, 29 according to FIG. 8.
  • the groups of three are connected to each other with special connecting elements 26 and 30.
  • the suspension is in turn carried out on the connecting elements or via a rack 31.
  • FIG. 35 The illumination of a large office space is shown in Fig. 12. Groups of three 32 according to FIGS. 6 and 8 are suspended according to a certain grid.
  • FIG. 13 shows a star-shaped arrangement of individual luminescent 33, which are suspended on the inside on a special connecting element 34 and on the outside on an annular element 35.
  • Individual lights 36 are arranged parallel to one another and connected to one another by means of suitable connecting elements or frames, in such a way that, due to the suitable number, a total of a square light field 37
  • the shape of the reflector which enables 100% luminous efficacy and both increases the service life of the lamps and prevents contamination by dust, makes fluorescent tubes also suitable for locations that are more difficult to access.
  • the very simple connection to 0 groups and luminaire arrangements for achieving large-area illuminations and high luminance enables for the first time the profitable use of fluorescent tubes also for lighting from greater heights, for example for almost glare-free floodlight systems.
