Definitions

  • the invention relates to a busbar system for a lighting module according to the preamble of claim 1.
  • Such a busbar system has a support profile for supporting the light module, the support profile having a cross section which is open in a first direction, for example downwards, and wherein a light generated by the light module is essentially emitted in the first direction.
  • a generic busbar system is from the EP 1 284 033 B1 known.
  • the device comprises two busbars running in parallel. Spot lights are arranged on the underside, lights on the top with a flat lighting effect.
  • the invention has for its object to provide a corresponding busbar system with which an improved indirect lighting is possible.
  • a busbar system for a light module which has a support profile for supporting the light module, the support profile having a cross section which is open in a first direction and wherein a light generated by the light module is essentially emitted in the first direction. Furthermore, the busbar system has a luminous element with a light source for emitting light in a second direction opposite to the first direction, the support profile having an opening on one side which points in the second direction, through which an optical element assigned to the light source extends extends.
  • the light element can be used to generate light in the second direction without shadowing from the support profile. In this way, improved indirect lighting is made possible. Because the light source or the optical element of the lighting element extends through the opening, the lighting element can be virtually integrated into the support profile. In particular, no additional superstructures on the upper side of the support profile are required for this. In addition, it is possible to use the lighting module, for example, to generate direct lighting and the lighting element to generate indirect lighting, so that the indirect lighting can be designed to be controllable independently of the direct lighting. The indirect lighting can thus be switched on and off in particular independently of the direct lighting and can be designed to be adjustable in the brightness and / or color temperature of the light.
  • the light source of the lighting element advantageously comprises a light emitting diode and / or a halogen lamp.
  • a light-emitting diode is a quasi punctiform light source that can be built in a very small space, so that a light source in the form of a light-emitting diode contributes to the fact that the conductor rail system as a whole can be designed to be particularly space-saving. The same applies to a halogen lamp.
  • the optical element of the luminous element advantageously comprises a lens and / or a reflector for targeted light guidance or influencing.
  • the light-emitting element advantageously adjoins the edge of the opening on all sides without gaps and / or has a surface area which is oriented in a plane with the edge of the opening. In this way, the risk of dirt and the like penetrating through the opening is reduced. This is particularly advantageous if the second direction points vertically upwards. A correspondingly flat surface area of the lighting element also facilitates cleaning of the support profile.
  • the support profile advantageously has an at least approximately U-shaped cross section with two U legs and a connecting leg connecting the U legs, the U-shaped cross section being open in the first direction.
  • the first direction can point vertically downwards, so that the two U-legs protrude downward from the connecting leg and the connecting leg forms an upward side, that is to say in the second direction, of the support profile in which the opening is located.
  • the busbar system also has a light module power supply line for supplying current to the light module, the light module power supply line being arranged within the support profile. In this way, protected, secure power supply to the lighting module is made possible.
  • the busbar system also advantageously has a lighting element power supply line for supplying current to the lighting element, the lighting element power supply line being arranged within the support profile. In this way, protected, secure power supply to the lighting element is made possible.
  • the lighting element power supply line is arranged on one of the two U-legs of the support profile.
  • the support profile advantageously also has further openings, each of which is designed in accordance with the opening mentioned first.
  • particularly uniform indirect lighting can be achieved if two adjacent openings each have the same distances from one another.
  • a further lighting element which corresponds to the first-mentioned lighting element is advantageously arranged in each of the further openings, the busbar system furthermore having a connecting power line for carrying current between the lighting elements, which is arranged within the support profile.
  • FIG. 1 a cross-sectional sketch of a first exemplary embodiment of a busbar system according to the invention is shown;
  • Fig. 3 shows a further, partially perspective sketch of this embodiment.
  • the busbar system is provided for a light module 3, which in Fig. 3 is symbolically indicated.
  • the busbar system comprises a support profile 2 for supporting the light module 3, the support profile 2 having a cross section which is open in a first direction u.
  • the support profile 2 can be provided to be arranged to operate the busbar system in such a way that the cross section is open at the bottom.
  • this is purely exemplary and does not represent any limitation, since the support profile 2 according to the invention is suitable for being used in any possible orientation with respect to gravity.
  • an orientation of the support profile 2 is assumed below, in which the first direction u points vertically downward. If the support profile 2 is oriented differently, the following directions are to be reinterpreted accordingly.
  • the lighting module 3 is held on the mounting rail 2 in such a way that it projects through the open area of the cross section downward from the mounting rail 2 or overall below the mounting rail 2.
  • the lighting module 3 can comprise a light source, for example an approximately tubular light source, it being provided for the arrangement of the lighting module 3 on the support profile 2 that the longitudinal axis of the light source is parallel to the main axis of the support profile 2. It can therefore be provided, for example, that - as in Fig. 3 indicated - the light module 3 is arranged with a tubular light source arranged parallel to the longitudinal direction of the mounting rail 2 on the underside of the mounting profile 2.
  • the busbar system is provided for receiving a plurality of identical or structurally identical lighting modules of the type mentioned, the lighting modules in particular either being provided at a certain distance from one another or directly adjacent to one another.
  • light generated by the lighting module 3 is emitted at least essentially downwards, that is to say in the first direction. This arises more or less automatically in the arrangement of the light module 3 as compared to the support profile 2.
  • “Essentially” means that the light module 3 is at least designed to emit light into the lower half-space. In particular, the lighting module 3 can be provided for generating direct lighting.
  • the support profile 2 for operating the busbar system is arranged in a room with a ceiling in such a way that it is at a distance from the ceiling, that is to say is arranged suspended from the ceiling.
  • the busbar system has a light-emitting element in order to generate a light emission in a second direction o - here upwards - opposite to the first direction 4 with a light source 6.
  • the lighting element 4 can be provided for generating indirect lighting over the ceiling.
  • the support profile 2 has an opening 10 through which the light source 6 of the lighting element 4 and / or an optical element 8 assigned to the light source 6 extends on a side which points in the second direction o, here upwards.
  • the lighting element 4 can be integrated into the support profile 2 or - viewed in cross section - into the profile profile of the support profile 2. It can thus be designed in a space-saving manner as a quasi-integral part of the support profile 4.
  • the opening 10 can be an opening through the support profile 2. With regard to the shape of the opening 10, it can be provided that its extension in the longitudinal direction of the mounting rail 2 is approximately the same size, for example the maximum is twice as large as its extension in the transverse direction. For example, a circular or square-shaped opening can be provided.
  • the mounting rail 2 is suspended, it is advantageously provided for the arrangement of the opening 10 within the mounting rail 2 that the point of application or the points of application for the suspension on the one hand and the opening 10 on the other hand are arranged in different longitudinal regions of the mounting rail 2 . In this way, a negative influence of suspension means of the mounting rail 2 on the light radiation of the lighting element 4 can be minimized.
  • the light source 6 of the lighting element 4 can comprise a light emitting diode and / or a halogen lamp.
  • a light-emitting diode can be designed in a very small space and thus allows an overall small-scale construction of the busbar system. The same applies in principle to a halogen lamp.
  • the optical element 8 of the lighting element 4 can comprise a lens and / or a reflector.
  • the optical element 8 extends in the form of a lens through the opening 10 or fills it.
  • the lighting element 4 has a preferably planar surface area which is oriented in a plane with the edge of the opening 10, that is to say, for example, horizontally.
  • Possible contamination can also be prevented by making the light exit surfaces of the lighting element as steep as possible, for example steeper than 70 ° or 80 °, since dirt cannot deposit on such steep surfaces as easily as on less inclined surfaces.
  • the support profile 2 can in particular have an at least approximately U-shaped cross-section with two U-legs 21, 22 and a connecting leg 23 connecting the U-legs 21, 22, the cross-section being open at the bottom, that is to say the U-legs 21 , 22 protrude downward from the connecting leg 23.
  • the opening 10 is thus arranged on the connecting leg 23, preferably in the center.
  • the busbar system preferably has a light module power supply line 30 which is arranged within the support profile 2.
  • the light module power supply line 30 can be arranged on the inside of one of the two U-legs 21, 22, for example via a holding profile 35 made of plastic, as in FIG Fig. 1 outlined so that the light module power supply line 30 and the holding element 35 are parts of a - arranged parallel to the longitudinal axis of the mounting rail 2 - Form current conducting profile. This arrangement enables a safe tapping of current from the inside of the support profile 2.
  • the busbar system preferably has a lighting element power supply line 31, which is arranged within the support profile 2.
  • the luminous element power supply line 31 can be arranged on the inside of one of the two U-legs 21, 22, for example also via the holding profile 35 made of plastic or the current conducting profile, as in FIG Fig. 1 outlined.
  • a current conducting profile can therefore be provided, which comprises both the light module power supply line 30 and the light element power supply line 31. This arrangement enables a safe tapping of current from the inside of the support profile 2.
  • the lighting module power supply line 30 is advantageously arranged below the lighting element power supply line 31, so that the current taps for the lighting module 3 on the one hand and the lighting element 4 on the other hand interfere with one another as little as possible.
  • the support profile 2 - as in FIG Fig. 3 indicated in perspective - also has further openings 101, 102, which are each designed in accordance with the opening 10 mentioned first, so that in each of the openings 101, 102 a further lighting element can be inserted, which corresponds to the lighting element 4 mentioned first or to the latter is identical.
  • indirect lighting can be generated, which is formed particularly uniformly along the supporting profile 2 on the corresponding ceiling.
  • the distances between the openings 101, 102 are preferably each the same.
  • a lighting element is inserted in each of the openings 101, 102.
  • a contact 40 for example in the form of a plug contact, can be provided for each of the lighting elements, via which current can be tapped from the lighting element power supply line 31 for the relevant lighting element 4 .
  • the assembly of the lighting elements in the mounting rail 2 individual lighting elements are inserted from the inner area of the mounting rail 2 into the openings and contacted accordingly.
  • a connecting power line 33 can be provided, which is arranged within the support profile 2 for carrying current between the lighting elements.
  • This connection power line 33 can in particular - as for example in Fig. 2 outlined - be arranged on the connecting leg 23. It is possible for the lighting elements 4 to be connected to one another in a pre-assembled manner, for example on a cable reel, by the connecting current line 33. For assembly, this pre-assembled unit can then be inserted into the mounting rail 2 from below. In this case, the lighting profile does not have to be in contact with the current conducting profile shown above.
  • a device at an end region of the mounting rail 2 can also be used to supply power to the lighting elements, or a corresponding (additional) device can be used in the mounting rail 2 in a central region, in particular in the case of a comparatively long mounting rail 2.
  • the lighting elements can tap a 230V supply line.
  • the color temperature of the light emitted by the lighting element 4 is designed to be adjustable.
  • Fig. 5 is a variant that is not the subject of the claims outlined. Unless otherwise stated, the above explanations apply mutatis mutandis to this variant.
  • the support profile 2 ' has two side walls 24, 25 which protrude freely in the second direction o or upwards and which - with respect to the second direction o - laterally delimit a space between them in which the lighting element 4' at least partially is arranged.
  • the support profile 2 ' can be made H-shaped overall be so that the two side walls 24, 25 form upward extensions of two legs 21 'and 22', which correspond to the two U-legs of the exemplary embodiments shown above.
  • the corresponding connecting leg 23 'in this case represents the middle bar of the "H".
  • a lighting element power supply line 31 ′ can preferably be provided, which is arranged on one of the two side walls 24, 25.
  • Two corresponding lines of this type can also be provided, each of which is arranged to run on one of the two side walls 24, 25.
  • a further current conducting profile can also be provided, which is arranged in the space between the side walls 24, 25.
  • the light modules arranged on the underside of the support profile can be freely positioned in the longitudinal direction of the support rail, that is to say in particular independently of the arrangement of the light elements. In other words, it must be possible to rule out the possibility of a collision between the light modules and the light elements.
  • the current conducting profile comprises a plurality of current conductors arranged one above the other, whereby only current conductors from a lower area are used to supply power to the lighting modules and only current conductors from a remaining, upper area are used to supply power to the lighting elements.
