The housing carries a lighting unit. The luminaire comprises an annular wall and a radially extending flange portion around the annular wall. The annular wall extending in an axial direction from the radially extending flange portion and at least a portion of the radially extending flange may be removable to allow mechanical connection between adjacent luminaires thus creating a lighting system. ## Claims ### Claim 1 A lighting system comprising a first luminaire and a second luminaire, each of the first and second luminaires comprising a housing and a lighting unit insertable into and removable from the housing, wherein the housing comprises a radially extending flange around an annular wall, the annular wall protruding in an axial direction around a central axis from a first main face of the radially extending flange, wherein the housing further comprises a clamping arrangement for clamping the housing to a carrier or substrate, the clamping arrangement being removable from the housing, wherein the first luminaire has a first radially extending flange with a first removable portion and the second luminaire has a second radially extending flange with a second removable portion, wherein after removal of said first removable portion and said second removable portion, said first and second radially extending flanges are connectable matching parts, which in mutually connected position form a shared flange. ### Claim 2 (depends on 1) The lighting system as claimed in claim 1, wherein the housing comprises multiple clamping arrangements, and wherein a first clamping arrangement alongside a face closest to the portion of the radially extending flange that is removable from the housing is removable. ### Claim 3 (depends on 1) The lighting system as claimed in claim 1, wherein the clamping arrangement is provided on a removable portion of the radially extending flange. ### Claim 4 (depends on 1) The lighting system as claimed in claim 1, wherein each of the first and second luminaires has a cross section orthogonal to the central axis, the cross section being one of a circle, ellipse, square, rectangle, triangle, hexagon or any other polygonal shape. ### Claim 5 (depends on 1) The lighting system as claimed in claim 1, wherein the radially extending flange comprises surface features or through-holes to demarcate at least one cutting line. ### Claim 6 (depends on 5) The lighting system as claimed in claim 5, wherein each of the first and second luminaires has a cross section orthogonal to the central axis, the cross section being a polygonal shape, and wherein each side of the polygonal shape has a respective cutting line extending adjacent and parallel to said side and over the full length of the radially extending flange at said respective side. ### Claim 7 (depends on 6) The lighting system as claimed in claim 6, wherein the polygonal shape has n sides, and wherein the radially extending flange is divided into 2*n removable portions by n cutting lines. ### Claim 8 (depends on 1) The lighting system as claimed in claim 1, wherein the annular wall (and/or the radially extending flange comprises a mechanical connector element. ### Claim 9 (depends on 1) The lighting system as claimed in claim 1, wherein the first radially extending flange, the second radially extending flange, and the shared flange have an equal width measured along a respective virtual line through a respective central axis and extending in a respective direction transverse to a respective annular wall. ### Claim 10 (depends on 1) A method of assembling the lighting system as claimed in claim 1, said method comprising the steps of: removing a selected first portion of the first radially extending flange of the first luminaire, removing a selected first clamping arrangement from the first luminaire, removing a selected second portion of the second radially extending flange of the second luminaire, removing a selected clamping arrangement from the second luminaire, connecting the first luminaire and the second luminaire to form a luminaire group suitable for receiving a plurality of lighting units, and inserting a respective lighting unit of a plurality of lighting units in a respective housing of the luminaire group. ### Claim 11 (depends on 10) The method as claimed in claim 10, the method further comprising; removing a selected further portion of a further radially extending flange from a further luminaire, removing a selected further clamping arrangement from the further luminaire, connecting the first luminaire, the second luminaire and the further luminaire to form the luminaire group. ### Claim 12 (depends on 10) The method as claimed in claim 10, the method further comprising: mounting the plurality of luminaires to a substrate or carrier. ### Claim 13 (depends on 10) The method as claimed in claim 10, the method further comprising the additional prior steps of: selecting a first luminaire having a first cross section orthogonal to its central axis, selecting a second luminaire having a second cross section orthogonal to its central axis, said second cross section being either equal or different in shape from the first cross section.
