Definitions

  • the invention relates to a fastening device for lighting means according to the preamble of claim 1.
  • a support body which has, for example, a U-shaped cross-sectional contour in order to be able to lock a large number of lighting means, in particular LEDs, to it.
  • the lighting means are connected to an electrical energy source by means of electrical lines.
  • the lamps can be switched on or off as required.
  • Such support bodies can be attached directly to ceilings or walls of rooms; it is also possible to hang the support body from the ceiling.
  • support bodies which often have a length extension of several meters, are embedded in floors and closed by a transparent cover plate that can be walked on. Regardless of the installation situation, the light sources emit a large number of light beams, which thus form a beam path and illuminate the neighboring areas.
  • the support body can also serve as a substructure or as a stiffener for a reflector that is mechanically coupled to the respective support body.
  • the reflector usually consists of a metallic material in lightweight construction, for example aluminum.
  • the reflector is U-shaped in cross section and the lighting means are arranged in the interior of the reflector, so that the light waves emitted by the lighting means are guided in the spatial direction through the two side walls of the reflector.
  • a diffuser is also provided, by means of which an illumination of a certain area which is as homogeneous as possible and which influences the brightness is achieved.
  • each individual illuminant has to be connected to the reflector.
  • a further alternative fastening consists in equipping a circuit board with a large number of the illuminants so that the circuit board is to be fixed to the reflector.
  • Such assembly work is extremely time-consuming and the supporting bodies are often already attached to the ceilings or walls and subsequent attachment of the lighting means is difficult due to the confined space situations.
  • this conversion work is difficult and requires specialist knowledge.
  • a beam path is often created on the sides, which blinds the side near the support body, since the light waves radiate into an area outside the desired alignment.
  • the object of the invention to develop a fastening device of the type mentioned at the outset in such a way that a large number of illuminants can be preassembled in order to be able to fasten them to the reflector and the support body in a time-saving and uncomplicated manner.
  • the large number of illuminants should have an aesthetically pleasing luminaire design and enable a given area to be illuminated as homogeneously as possible.
  • an insert element is provided in the respective beam path of the illuminant and that the respective insert element is held centered by the diffuser and as soon as the support body is attached to a ceiling, wall or the like, the respective insert element can be pushed or snapped into the diffuser and becomes aligned at the same time as the diffuser is attached aligned with the longitudinal axis of the support body, so that the beam path is influenced by the respective insert element in such a way that lateral radiation of the light waves, which creates a glare effect, is prevented.
  • a reflector is provided which is attached to the support body and the diffuser.
  • At least one compression spring is formed or provided on each side of the insert elements, which in the unloaded state protrude beyond the free end face of the insert elements. Two adjacent insert elements are therefore coupled to one another in the unloaded state via a contact surface of the compression springs and as soon as a corresponding linear expansion of the insert elements occurs, the pair of adjacent compression springs is loaded and, due to their compensatory movements, the linear expansion of the insert elements can be compensated.
  • the compression springs accordingly bend inwards or outwards and thereby compensate for the linear expansion of the insert elements.
  • the insert elements can have optical properties, because both the reflective properties of the respective surfaces of the insert elements can be designed differently and the existing angular alignment of the side walls of the insert elements is designed in such a way that the light rays are preferably emitted at a maximum, preferably in a total opening angle between 40 ° and 70 ° are.
  • visor bodies are provided between the respective adjacent lighting means, which have a rectangular, elliptical, concave or convex curved outer contour, through which the respective beam path of the light rays of the lighting means is influenced and aligned accordingly.
  • the insert elements are floatingly mounted on the support body and have compression springs on their respective end faces, which rest against one another with their respective contact surfaces both in the loaded and in the unloaded state and consequently compensate for the linear expansion of the insert elements arranged in series if corresponding temperature fluctuations occur .
  • existing lights that have a correspondingly designed support structure in the form of the support body according to the invention can be retrofitted by means of the fastening device according to the invention, because the fastening device has a modular structure, the individual components of which are easily adapted to the specified installation situation or geometries can be adapted from the support body.
  • FIG. 1 a room 10 of a building is shown in perspective and schematically, on the ceiling of which a fastening device 1 is attached.
  • the fastening device 1 comprises a multiplicity of lighting means 2, by means of which the room is to be illuminated in a certain area, without light waves emerging from the side, in order to avoid dazzling effects.
  • the respective lighting means 2 are connected to an electrical energy source 6 by means of electrical lines 5.
  • a switch 7 is provided in the electrical lines 5 between the respective lighting means 2 and the energy source 6, which switch can usually be operated from the outside.
  • Such a switch 7 can be replaced by a radio control or WLAN connections.
  • a support body 3 is provided, the cross-sectional contour of which is U-shaped.
  • the support body 3 can be attached directly to the ceiling of the room 10 or the support body 3 is suspended from the ceiling, for example by means of wires.
  • FIG 2a the structural design of the fastening device 1 can be seen.
  • the bottom of the U-shaped support body 3 faces the ceiling of the room 10 and is attached to it, so that the side of the support body 3 facing the floor of the room 10 is open in order to ensure that the light rays emitted by the illuminants 2 in the direction of the room 10 and therefore have a predetermined beam path 20.
  • a reflector 16 is to be received by the support body 3, the cross section of which is essentially U-shaped or V-shaped.
  • the lighting means 2 or circuit boards 2 ' should be received by the reflector 16.
  • the circuit boards 2 ′ carry a large number of the illuminants 2.
  • the two side walls 18 of the reflector 16 are inclined outward and the beam path 20 of the light waves emitted by the illuminants 2 accordingly runs between the side walls 18 of the reflector 16.
  • an L-shaped leaf spring 21 is provided on each of the side walls 18, which for one is connected to the reflector 16 via a type of hinge 22; and the free end 24 of the leaf spring 21 is inserted into a bore 23 machined into the side wall 18 and relatively supported therein.
  • the leaf spring 21 can be compressed in the direction of the reflector 16 in order to reduce the outer distance.
  • Support strips 30, which interact with the respective leaf spring 21, are provided in the interior of the support body 3.
  • the middle support strip 30 centers the leaf spring 21 in such a way that the reflector 16 is aligned with its longitudinal axis coaxially to the longitudinal axis 4 of the support body 3.
  • the support strip 30 assigned to the open side of the support body 3, on the other hand, is oriented towards the bottom of the support body 3 and the respective leaf spring 21 rests on the free end of this support strip 30 so that the reflector 16 is held on the lowermost support strip 30 by the leaf spring 21 .
  • an insert element 11 is provided or arranged in the beam path 20.
  • the insert elements 11 have two outwardly inclined side walls 31 which enclose an opening angle of 40 to 70 °, between which the beam path 20 is aligned.
  • the insert elements 11 therefore serve to exclude the dazzling effect of the lighting means 2 as far as possible, since the alignment of the beam path 20 is precisely predetermined and consequently the dazzling effect in the lateral area of the support body 3 is avoided.
  • the insert elements 11 are inserted in the reflector 16 and are held in a centered manner, on the one hand, by a diffuser 8 and a plurality of retaining clips 25 attached in sections - as explained in more detail below.
  • the retaining clip 25 has two oppositely aligned support feet 27 which are each assigned to a through opening 26 machined into the side wall 18 of the reflector 16 and which extend through this. As a result, the support feet 27 run partially in the interior of the reflector 16 and act on the diffuser 8, since these are connected to one another in the manner of an undercut.
  • the diffuser 8 Since the diffuser 8 has a cap-like cross section, which generates a pretensioning, and since the respective retaining clips 25 exert an inwardly directed force on the diffuser 8, the diffuser 8 is protected by the retaining clips attached in sections 25 coupled to the reflector 6. In addition, the diffuser 8 holds the circuit board 2 ′ and the insert elements 11 arranged in the beam path 20, since the inner contours of the diffuser 8 are designed in such a way that both the circuit board 2 ′ and the insert elements 11 are fixed by the diffuser 8.
  • two support arms 14 with a predetermined possibility of pivoting movement are provided on the insert elements 11 in pairs on one longitudinal side.
  • the support arms 14 protrude perpendicularly from the side walls 31 of the insert elements 11 and are essentially bent in an L-shape, so that the support arms 14 are not only pivotably attached or mounted on the insert elements 11, but the free ends of the support arms 14 can also move in the direction of the insert element 11 be compressed when a correspondingly large pressing force acts on it through the diffuser 8.
  • the respective insert elements 11 are placed on the bottom of the reflector 16 and the diffuser 8 engages around or encloses the respective insert element 11 in such a way that the diffuser 8 rests on the one hand on the inner wall of the legs of the retaining clip 25 and on the other hand against the support arms 14 of the insert elements 11 and consequently establishes a permanent operative connection between the retaining clips 25 and the insert elements 11, by means of which the insert element 11 is mounted in a floating manner and through which the support arms 14 of the insert element 11 are aligned with the longitudinal axis 4 of the support body 3.
  • the strips 30 of the support body 3 form a stop for the respective leaf spring 21, so that the respective insert element 11 is snapped into place between the strips 30 of the support body 3.
  • the leaf springs 21 are compressed in the direction of the interior of the support body 3, whereby their distance is reduced. As soon as the respective insert element 11 is snapped into the supporting body 3, the leaf springs 21 exert an outwardly directed holding force so that the respective insert element 11 is connected in a position-oriented manner in the supporting body 3 or with the supporting body 3.
  • the diffuser 8 therefore serves, on the one hand, to combine the light beams 20 emitted by the lighting means 2 as homogeneously as possible and to influence them in the direction of the interior of the room 10 in a predetermined radiation direction and, on the other hand, the diffuser 8 fixes the respective insert elements 11 so that they are coaxial are aligned with the longitudinal axis 4 of the support body 3.
  • the support arms 14 protruding perpendicularly from the respective insert elements 11 are thus acted upon by the holding clip 25 and the diffuser 8 with a holding force.
  • the fastening device 1 can consist exclusively of the support body 3, the diffuser 8 and the lighting means 2 or the circuit board 2 ′ with the lighting means 2.
  • the use of a reflector 16 according to Figure 2a is therefore not required.
  • the support body 3 therefore not only locks the electrical components 2, 2 ′ and 5 but also fixes the insert elements 11 and the diffuser 8.
  • the retaining clips 25 are connected to the support body 3 in sections. In the support body 3, passage openings are incorporated at the corresponding positions, through which the support feet 27 of the retaining clip 25 are passed and come into operative contact with the outer sides of the diffuser 8.
  • the support feet 27 are designed in such a way that they form a type of undercut and corresponding webs are provided on the diffuser 8, which are encompassed by the support feet 27 and are consequently fixed on the support body 3 by the retaining clips 25.
  • the insert elements 11 and the lighting means 2 are provided, which are kept centered by the diffuser 8 in the prescribed manner. Furthermore, the diffuser 8 can be followed by a film 9 in the beam path 20 of the lighting means 2, which further influences the homogeneity and the direction of emission of the emitted light waves.
  • FIG 3a the isolated insert element 11 can be seen, which is designed as a U-shaped rail.
  • a plurality of receiving openings 15 are incorporated into the insert element 11, into each of which one of the illuminants 2 can be inserted and can be locked at this.

  • Visor bodies 17 are provided between the receiving opening 15, which protrude from the plane formed by the receiving opening 15 and thus lie in the beam path 20 of the light waves that are emitted by the lighting means 2.
  • the outer contour of the visor body 17 is designed to be elliptical, concave or convexly curved, depending on the desired reflection effect that is to be exerted on the respective light beams of the lighting means 2.
  • the surface property of the insert elements 11 can be designed to be reflective or slightly reflective, for example by means of corresponding paint applications, in order to influence the light intensity and / or the illumination characteristics of the lighting means 2.
