Each suspension element comprises an upper fixing part and a lower connection part facing downwardly for making electrical and mechanical connection to an upward facing connector on a top face of an end of a linear lighting element. This enables a simple a push fit connection of the lighting elements to the suspension elements, after they have been suspended from a support structure above them. ## Claims ### Claim 1 A lighting system, comprising: a set of linear lighting elements; and a set of suspension elements for suspending the lighting elements from a horizontal support, wherein each suspension element comprises an upper fixing part for fixing to the support and a lower connection part for making electrical and mechanical connection to an end of a linear lighting element, wherein the lower connection part comprises a first electrical and mechanical connector at its bottom end for facing downwardly in use, and the linear lighting elements each comprise a second electrical and mechanical connector at each end for facing upwardly in use, wherein the connection between the first and second connectors is a push fit connection, and wherein at least one suspension element comprises an external electrical connection, and wherein a first one of the suspension elements comprises a lower connection part which comprises: a first suspended support for making electrical and mechanical connection to an end of a first linear lighting element; and a second suspended support for making electrical and mechanical connection to an end of a second linear lighting element, wherein the first and second suspended supports are butted back to back and an electrical connection is provided between the first and second suspended supports of said first one of the suspension elements. ### Claim 2 (depends on 1) A lighting system as claimed in claim 1, wherein a second one of the suspension elements comprises a lower connection part which comprises: a first suspended support for making electrical and mechanical connection to an end of a first linear lighting element; and a second suspended support for making electrical and mechanical connection to an end of a second linear lighting element, wherein the first and second suspended supports are angularly positioned or positionable at 90 degrees to each other about a suspension direction and wherein the upper fixing part provides electrical connection between the first and second suspended supports. ### Claim 3 (depends on 2) A lighting system as claimed in claim 2, wherein the first and second suspended supports of the second one of the suspension elements are rotatable about the suspension direction. ### Claim 4 (depends on 2) A lighting system as claimed in claim 2, wherein the first and second suspended supports of the second one of the suspension elements are spaced apart along the linear lighting element direction. ### Claim 5 (depends on 1) A lighting system as claimed in claim 1, wherein a third one of the suspension elements comprises a lower connection part which comprises: a single suspended support for making electrical and mechanical connection to an end of a first linear lighting element. ### Claim 6 (depends on 1) A lighting system as claimed in claim 1, wherein the upper fixing part of each suspension element comprises a pair of spaced apart grips each for gripping opposite edges of a horizontal strip-shaped support and a pair of spring fingers each on an opposite side of the upper fixing part to a respective grip, for implementing a twist and lock attachment to the horizontal support. ### Claim 7 (depends on 1) A lighting system as claimed in claim 1, further comprising a decorative cover covering the upper fixing part, wherein the decorative cover comprises a recess with a pair of opposing end walls, the upper fixing part comprises a protruding portion which is adapted to rest in the recess and a pair of extending tips frictionally abutting against the end walls for holding decorative cover. ### Claim 8 (depends on 1) A lighting system as claimed in claim 1, wherein the upper fixing part of each suspension element comprises a pair of spaced apart lips each for hooking over opposite edges of the horizontal support, wherein the spacing between the lips is adjustable. ### Claim 9 (depends on 8) A lighting system as claimed in claim 8, wherein the upper fixing part of each suspension element comprises a slider for manually increasing the spacing and a spring arrangement for closing the spacing. ### Claim 10 (depends on 8) A lighting system as claimed in claim 8, wherein the spacing is adjustable to include at least the range 16 mm to 24 mm. ### Claim 11 (depends on 1) A lighting system as claimed in claim 1, wherein each linear lighting element comprises an electrical connection port at each end, comprising the second electrical and mechanical connector, for connection to the lower connection part of a suspension element. ### Claim 12 (depends on 1) A lighting system as claimed in claim 1, wherein each linear lighting element comprises an LED strip or tube. ### Claim 13 (depends on 1) A lighting installation comprising: a grid of strip-shaped horizontal supports; and a lighting system as claimed in claim 1. ### Claim 14 (depends on 13) A ceiling installation comprising: a lighting installation as claimed in claim 13, with the set of linear lighting elements suspended below the grid of strip-shaped horizontal supports; and a set of ceiling tiles fitted in the grid spaces of the grid of strip-shaped horizontal supports. ### Claim 15 (depends on 14) A ceiling installation as claimed in claim 14, wherein the set of linear lighting elements are adapted to project light upwards; and wherein a distance between the linear lighting elements and the ceiling tiles is in a range of 5 cm to 15 cm.
