• the light distribution element 61 has the shape of a trough-shaped basket 121, the cross-sectional shape of the basket being rounded (FIG. 8) or with several, For example, four, in each case an obtuse, angle can be formed between flanks 122 (FIG. 7), the corners enclosed by flanks 122 preferably being rounded.
• the top of the basket 121 can be arranged horizontally or inclined outwards on both sides.
• the basket 121 is detachably attached to the base body 5 with its end walls 121a directly or by means of the quick-connect connection or latching device 26.
• the design of the light distribution element 61 as a basket 121 is particularly advantageous when the first indirect lighting device 3 is to be assigned more lighting power.
• the basket 121 can be designed on its inside as a reflector, which at least partially reflects the light rays supplied by the lamp 23 upwards through the basket opening on the top, see distances b.
• the reflector 27 or the side reflectors 29 or the inner and outer walls 35, 36, and / or the light distribution elements 61 and / or the basket 121 consist of translucent or translucent and / or perforated walls, so that in each case depending on the light transmittance of one or the other lighting device 2, 3, 4, more lighting power can be measured.
• the light distribution elements 61 can extend in a straight or concave curve, whereby they can form extensions of the contour shape of the side surfaces 7 (for example FIGS. 7 and 8) or for example be straight and slightly angled downwards (FIG. 1).
• the light distribution elements 61 thus form indirect distribution elements, which contribute both to the lighting of the room and to the lighting of the room above the lamp 1, both with direct attachment to the ceiling 71 and with a suspended attachment.
• the property described above depends on the design of the light distribution elements 61, namely translucent, translucent and / or perforated.
• the light distribution elements 61 have reflection surfaces 61a on their undersides, which can be formed, for example, by a coating, they form indirect reflectors. They can be translucent, translucent and / or perforated at the same time for the purpose of illuminating the room above.
• the side surfaces 7 of the base body 5 can also be reflective (bare or coated) and form reflection surfaces.
• cross-connection section 111 or the hold-down device 115 on its upper side as a reflector, so that light incident from the lamps is reflected against the ceiling, which also contributes to the indirect illumination of the ceiling area.
• the illustration of the lamp 1 according to FIG. 9 is intended to illustrate the possible variations that enable the configuration according to the invention. It is namely possible to optionally equip a light distribution element 61 in the form of a reflector 27 with an inner wall 35 and outer wall 36, a reflector 27a with only one inner wall 35 or with a basket 121 on one and the same base body 5. This also applies to the light distribution elements 61 in the various configurations described, which can optionally be attached to the base body 5. This is possible because the respective connecting device parts of the aforementioned parts which can be optionally fitted (light distributor 25, light distribution elements 61) match the associated connecting device parts on the base body 5
• the direct lighting device 2 has one or more spotlights 125, which are preferably connected to the by means of a quick-action connection 126 or a longitudinal sliding guide 127 lower corner area of the base body 5 connected, preferably longitudinally displaceable in the sliding guide 127 and can be locked by a locking device 128.
• the sliding guide 127 can extend over the entire length of the base body 5 or only over a partial area thereof, it also being possible for a plurality of sliding guides 127 to be arranged one behind the other in the longitudinal direction. As shown in FIG.
• the sliding guide 127 is formed by a guide profile 128 with undercut guide surfaces 129, on which a guide carriage 132 carrying the radiator 125 surrounds and is displaceable.
• the respective locking of the locking device can take place, for example, by means of a manually operable screw part 133.
• the guide profile 128 can take place on the lower mounting surface 6 or on a special mounting surface 134 which is formed by a recess on the underside, e.g. a cutout can be formed.
• the mounting surface 134 is located between the two screw channels 14, 15.
• the blasting head 125a of the radiator 125 is preferably pivotable and can be locked in the respective pivoting position by means of a locking device 125b.
• 128 mounting rails for the electrical circuit can be assigned to the fastening foot or the guide profile (not shown), which are connected to current collectors (contacts or sliding contacts) of the circuit.
• a fastening device 141 preferably also formed by a quick-connect connection or plug device, for a panel 142 or the like is arranged on whose side surfaces are also advertising space for advertising or a wing for written or graphic references, e.g. Directional arrows 143 and / or words, such as emergency exit, are applied.
• This configuration is advantageous because, on the one hand, the advertising surface or wing can be attached in a clearly visible position below the lamp 1 and, on the other hand, is illuminated by the lamp 1.
• the fastening device 141 can be formed by a sliding guide, in particular a guide groove 144 of a guide rail 145 be, into which a correspondingly shaped holding foot 146 of the board is inserted and held in a form-fitting manner.
• the guide rail 145 can also be designed as a lamp housing with a lamp 147 for illuminating the panel 142.
• the at least one panel 142 from translucent or translucent material, preferably plastic.
• the luminaire 1 in a straight extension, but e.g. train round (rotation profile).
