    FIG. 1 illustrates in a perspective view a modular lighting system 1 according toone aspect of the present invention. The modular Iighting system 1 comprisesan electric fitting 3 adapted to be mounted to and suspended from a ceilingbeam system 5. The electric fitting 3 is arranged for fitting of a tubular LED-lamp7. The electric fitting 3 comprises a housing 9 made of sheet blank forming abottom section 13 (lower side) having a grid 15 and two side-walls 17', 17". Thegrid 15 is made integrally in one piece with the bottom section 13 (lower sideopposite an upper side 14) for stiffening the housing 9. A first end body 19 isarranged at a first end 20 of the electric fitting 3 and partly inserted between thetwo side-walls 17, 17". The first end body 19 comprises a base fundament 23and a first 25 and second 27 flange end extending in opposite directions anbeing arranged offset relative each other. A second end body 21 is arranged ata second 22 end of the electric fitting 3 and partly inserted between the twoside-wall 17', 17". The first 19 and second 21 end body comprises a ZED-shaped (bent) sheet material 28 (e.g. metal or plastic). A reflector 29 isdismountable arranged for forming a portion of the upper side 14 of the housing9 between the end bodies 19, 21. The base fundaments 23 of respective endbody 19, 21 serve as upper end covers 31, which together with the reflector 29form a common upper cover UC of the housing 9. Flanges (or grooves) 33 arearranged inside the side walls 17', 17" at the first and second end 20, 22 of thehousing 9 for engaging the respective first 19 and second 21 end body. Anelectrical contact 35 is rigidly mounted to the second flange end 27 of the firstend body 19. Tongues (not shown) are provided to the first end body 19 forengagement with corresponding apertures (not shown) of the side-walls 17', 17"at the first end 20 for locking the first end body 19 in an end position. The endposition is determined so that when the first end body 19 is locked in the endposition, the electrical contact 35 will engage a contact of a contact surface of amounted LED-lamp 7. The electrical contact 35 is adapted to provide contactwith the LED-lamp after fitting. A capsulated LED driver transformer 37 is rigidlyfastened onto the base fundament 23 of the first end body 19. The electricalcontact 35 is coupled to the capsulated LED driver transformer 37 viapermanently sealed electrical cables 38. A first light socket 39' is rigidlymounted to the the second flange end 27 of the first end body 19 and a secondlight socket 39" is rigidly mounted to the second end body 21 to hold the LED- 11 lamp 7 and to allow for its replacement. The space between the first 39' andsecond 39" light socket forms an elongated light source compartment 41. Thelength of the compartment 41 corresponds to the distance between the first 39'and second light socket 39" and essentially to the length of the LED-lamp 7.When the first and second end body 19, 21 are fixed in respective end position,the electric fitting 3 is ready to receive and hold the LED-lamp 7. Thecapsulated LED driver transformer 37 comprises a contact member 45 adaptedto be connectable to a contact element 47 of a general-purpose alternating-current electric power supply (not shown) for electrical transferring of current.The respective first flange 25 of the first and second end body 19, 21 isfoldable. The first flange 25 can be pivoted to be in the same plane as the basefundament 23. This provides a transportation package not being bulky butrather suitable for compact storage and transport. The first and second flange25, 27 comprises an end edge 43, which is formed with a hook 44 for mountingthe electric fitting 3 to the ceiling beam system 5.
    FlGs. 2a to 2d illustrate an example of how to change electronics of the electricfitting 3. FIG. 2a illustrates one aspect of the modular lighting system 1according to the invention. An interchangeable first end coupling fixture body 19comprises a self-contained electrical supply means 37 and an electricalcoupling member 35, which are electrically connected to each other and bothbeing rigidly mounted to the interchangeable first end coupling fixture body 19.The self-contained electrical supply means 37 comprises a contact member 45adapted to be connectable to a contact element 47 of a general-purposealternating-current electric power supply (not shown) for electrical transferring ofcurrent. ln Fig. 2b is shown that in a first step the electric fitting 3 has beentaken down from the ceiling beam by disengaging a hook 44 of theinterchangeable first end coupling fixture body 19 from a beam flange. ln a nextstep the contact member 45 is disconnected from the contact element 47. ln ayet further step a latch 50 is released by a finger of an user (not shown) so thatthe interchangeable first end coupling fixture body 19 can be freely undockedfrom the housing 9 of the electric fitting 3 as can be seen in Fig. 2c. The userreplaces the interchangeable first end coupling fixture body 19 with a newinterchangeable first end coupling fixture body 19' comprising a brand-new self- 12 contained electrical supply means 37', an electrical coupling member 35' and anew contact member 45'. The user mounts and pushes the newinterchangeable first end coupling fixture body 19' until it finds its end positionbeing determined so that the electrical contact 35' will contact a contact of acontact surface of a mounted LED-lamp or other light source when mounted.The end position is determined by a stop member 61 and the latch 50. Thecontact member 45' is plugged into the contact element 47 (see FIG. 2b) andthe electric fitting 3 is hanged into place in the ceiling by hanging the hook 44' ofthe interchangeable first end coupling fixture body 19' to the ceiling beam.

Four electricfittings 3 (and two electric fittings illustrated with dashed lines) are mounted tothe ceiling beams. FIG. 3b illustrates an interchangeable first end couplingfixture body 19 and an elongated box-like support module 3. The elongatedbox-like support module 3 is cost-effective manufactured by forming a U-profileof sheet blank material and making it integral with a grid 15 for simplifying themanufacture and to enhancing the strength of the elongated box-like supportmodule 3. The fulfilled docking of the interchangeable first end coupling fixturebody 19 into the first end 20 of the elongated box-like support module 3 impliesthat the elongated box-like support module 3 further will be stabilized andstrengthened. The interchangeable first end coupling fixture body 19 comprisesa sheet material 28 being bent in Z-shape forming a base fundament 23 and afirst 25 and second 27 flange end. The base fundament 23 exhibits a back sideproviding a support surface for a permanently mounted sealed driver 37 andfurther exhibits an upper side 16, which will form a portion of an upper side 14of the elongated box-like support module 3. A reflector is 29 is detachablemounted to the upper side 14 and rests with its short edges 30 (its oppositeends, just one seen in a direction along the longitudinal axis X) onto the upperside 16 of the interchangeable first end coupling fixture body 19. By using thebase fundament 23 as a part of the upper side 14 material and weight can besaved. 13 FIG. 4 illustrates in cross sectional view a modular lighting system 1 accordingto one aspect of the present invention. The electric fitting 3' is a multi-lampIighting comprising a first and second end body 19", 21 A combined driver andcontact/holder unit 70 is rigidly mounted and sea|ed to the respectively first andsecond end body 19', 21 '_ FIG. 5a illustrates an interchangeabie first end coupling fixture body 19comprising sea|ed electronics (self-contained electrical supply means 37,electrical coupling member 35, contact member 45) rigidly mounted thereon andprepared to be coupled to a general-purpose alternating-current electric powersupply. FIG. 5b illustrates the interchangeabie first end coupling fixture body 19in a flat state (unfolded) before folding up the first flange 25 comprising thesuspension means 46. FIG. 5c shows an example offlat packages suitable fortransport, each package comprising the housing 9, first and second end body19, 21 and reflector 29. The first flanges 25 are unfolded. The first flange 25 isjoined to the base fundament (sheet face of same material as the first flange)via flexible joint or hinge 42 (see FIG. 5b).
    FlGs. 6a to 6b illustrate in cross-section the replacement of a driver unitaccording to one further aspect. FIG. 6a shows demounting of the electric fitting3. The interchangeabie first end coupling fixture body 19 in this embodimentcomprises a U-shaped sheet material 28' and a compact driver 37. ln FIG. 6b isshown removal of the reflector 29 by just lifting it from the housing 9 without anytools. Thereafter the LED-lamp 7 easily can be changed from above. lf there isa need for changing the driver 37, the first end body 19 just being undocked in adirection W and replaced by a new first end body comprising a new driver.
    FIG. 7a shows a further aspect of the present invention. The interchangeabiefirst end coupling fixture body 19 in this embodiment comprises an L-shapedsheet material 28" to be locked in end position. The grid 15 has a prolongationin the longitudinal direction extending between flanges 27' of the respective endbody 19 (only one is shown). The fixture body 19 is tilted and released fromhousing 9 over tilting point T. A suspension means 46' is formed of the sheetmaterial 28" for insertion into a ceiling aperture. FIG. 7b shows yet a further 14 aspect of the present invention. ln this case the interchangeable first endcoupling fixture body 19 comprises a plane sheet material 28"' onto which asealed combined driver and contact/lamp-holder unit 70' is permanentlymounted. A brand-new interchangeable first end coupling fixture body 19comprising a new permanently mounted unit 70' is docked into the housing 9.FIG. 7c shows a further aspect wherein the a driver and contact unit is mounted on a substrate comprising a foldable web.
    FIG. 8 i|ustrates a first end 20 of an elongated box-like support 3 made integralwith a lighting grid 15, both made integral in metal sheet in one piece. Theelongated box-like support 3 is fo|ded as U-profile with guide f|anges 90 forguiding the docking and for fixedly holding of an interchangeable first endcoupling fixture body 19 (see FIG. 9). The lighting grid 15 is produced by metalstamping of the blank metal sheet material into a lower side 13 to put outapertures 91 and form lamella segments 92 each exhibiting a semi-circularopening 93, partly through which a tubular LED-lamp may extend. Thereafterbending/folding of said lamella segments 92 is performed so that they extendorthogonally relatively to the plane of the lower side 13. Bending/folding isperformed simultaneously for forming the side walls 17', 17" merging with thelower side 13. Thereby is achieved a cost-effective method for producing amodular lighting system by stamping and bending/folding of a sheet material ina single stage procedure. At the same time there is achieved a rigid elongatedbox-like support 3 comprising the integral lighting grid 15. Each guide flange 90comprises three locking slots 94 having guidance lugs 96 arranged to receiveand guide corresponding flexible locking tongues 95 of a base fundament 23(see FIG. 9) of the interchangeable first end coupling fixture body 19 for lockingthe latter into an end position in the elongated box-like support 3. The guidef|anges 90 and the guidance lugs 96 and locking slots 94 are preferably alsofo|ded and stamped in the same stamping procedure. By this means no screwsor other fastening members have to be used for assembly of the electric fitting(modular lighting system). Just a set of the guidance lugs 96 and locking slots94 and locking tongues 95 has to be used for assembly. And can be operatedmanually without tools. The number of slots and tongues may vary. ln onepreferred embodiment there are six locking tongues 95 (three at each side meeting respective guide flange Iocking slots 94) of respective end couplingfixture body 19, 21 _ FIG. 9 illustrates in perspective view an end portion of the box-like support 3shown in FIG. 8. An interchangeable first end coupling fixture body 19 is dockedinto and fixedly mounted to the first end 20. A suspension means comprises afirst flange 25 of the body 19 and is formed as a (with two 90 degrees corners) folded hook member 97 in one folding step.
    FIG. 10 illustrates a method of producing the elongated box-like support 3comprising the integral lighting grid 15 according to one aspect of the presentinvention. Step 101 marks the starting of the procedure. A sheet metal is formedby means of metal stamping in performing Step 102 for producing the apertures91 and forming the lamella segments 92 at the same time as the Iocking slots94 are put out for arranging of guidance lugs 96 in the respective Iocking slots94. The method requires a stamping press and die corresponding to the designto be achieved. A steel punch forces the die into the blank sheet material withhigh pressure cutting out the material to be removed. ln Step 103 a foldingprocedure is performed for folding the lamella segments 92 to extendorthogonally from the lower side 13 and in Step 104 the sheet metal is foldedforming side walls 17”, 17” and also forming the guide flanges 90, wherein theside walls 17”, 17” merging with the lower side 13 and extend orthogonallytherefrom. ln Step 105 the elongated box-like support 3 is painted. ln Step 106the method is stopped and the elongated box-like support 3 is finished. Theinterchangeable first end coupling fixture body 19 and the second end couplingfixture body 21 also comprise sheet material subjected to metal stampperformance and bent to identical shapes. An aperture corresponding to aholder projection of a LED-lamp may be provided in the second flange of the second end coupling fixture body 21.
    After the procedure of stamping and folding the bodies 19, 21, mounting of theself-contained electrical supply means 37, the electrical coupling member 35, and the second light source holding element is performed onto the second endcoupling fixture body 21. The interchangeable first end coupling fixture body 19 16 and the second end coupling fixture body 21 can thereby be produced cost-effective in the same stamping/folding procedure. The self-contained electricalsupply means 37 may be permanently riveted to the interchangeable first endcoupling fixture body 19.
    FIG. 11 illustrates a cross-section of an electric fitting according to one aspect.A box module 3 encompasses a grid 15 (integrally made with the box module).A reflector 29 is positioned onto the bottom 13 of the box module 3.
    FIG. 12 illustrates a modular lighting system comprising an elongated box-likesupport module 3 made integral in one piece comprising a lighting grid member15. An interchangeable first end coupling fixture body 19 comprising a self-contained electrical supply means (could be a LED-driver) 37 and an electricalcoupling member 35, which are electrically connected to each other and bothbeing rigidly mounted to the interchangeable first end coupling fixture body 19.The interchangeable first end coupling fixture body 19 is demountable dockedinto the box module 3. The motion of docking is performed in the direction ofarrow D. ln an end position (not shown) is the interchangeable first end couplingfixture body 19 locked in the box module 3. The electrical coupling member 35is arranged for providing electrical contact with a light source 7 when the latteris fitted into the modular lighting system 1. The interchangeable first endcoupling fixture body 19 comprises a foldable suspension means 44 adapted tosuspension mounting. A second end 22 of the box module 3 is also arrangedwith a foldable suspension means 100.
    The present invention is of course not in any way restricted to the preferredembodiments described above, but many possibilities to modifications, orcombinations of the described embodiments, thereof should be apparent to aperson with ordinary skill in the art without departing from the basic idea of theinvention as defined in the appended claims. The elongated box-like supportmodule is made integral in one piece comprising a lighting grid member. Thelighting grid member may be fasten to the elongated box-like support module bymeans of adhesive, rivets, bolts, welding, folding or clamping or combinationsthereof or other suitable fastening means. The elongated box-like support 17 module extends along a central axis. The elongated light source compartmentand the light source (when fitted) and the elongated reflector means extend in adirection parallel with the central axis. The direction of motion of undocking anddocking of the interchangeable first end coupling fixture body (and thereby themotion of the thereto provided electrical contact) from and into the elongatedbox-like support module is preferably parallel with the central axis. Theinterchangeable first end coupling fixture body and the second end couplingfixture body each comprises a suspension means adapted to suspensionmounting, which may comprise a beam assembly system from which theelongated box-like support module suspends with other elongated box-likesupport modules of the same design. The beam assembly system may consistof interlinked beams in a cross-joint application forming a gridiron pattern. Eachelongated box-like support module may be positioned in-between two beamsand suspended therefrom by means of the suspension means of theinterchangeable first end coupling fixture body and of the second end couplingfixture body. The elongated reflector means may rest with its long edges ontothe bottom face of the elongated box-like support module and/or with its outerends onto the upper face of the first and second end coupling fixture bodies.The elongated box-like support module is preferably extending in a longitudinaldirection which is orthogonal to the prolongation of the beams. The sheetmaterial can be of a variety of materials and thicknesses depending uponspecific design requirements and from specific tolerances and applications. Thestamping can be performed in a so called single stage. According to one aspectof the invention the single stage method is highly suitable for producing theelongated box-like support module made integral in one piece comprising thelighting grid member. This implies cost-effective production. Of course, alsocomplex designs according to further aspects can be produced by multipleoperations. The self-contained electrical supply means and the electricalcoupling member may be rigidly mounted to the interchangeable first endcoupling fixture body.
