Description

Luminaire with an improved release mechanism [0001] This present invention relates to a luminaire, in particular, but not exclusively, to a luminaire for installing onto a ceiling or a wall.

BACKGROUND

[0002] Lighting assemblies such as luminaires often have a casing mounted into a ceiling or wall. These casings often house a light fixture which retains a light source. Lighting assemblies attached to the ceiling or wall in this way are designed to project light substantially in an outward direction. To install such a light assembly, the casing typically has one or more retaining clips or torsion springs. These retaining clips or torsion springs are held against the casing before it is mounted to the wall or inserted into a hole or recess in the ceiling. When the retaining clips or torsion springs are released, they urge outwards so as to engage and frictionally retain the casing in the recess or hole. The light fixture is then typically retained in the housing by methods known in the art such as, for example, a threaded screw fixing, a slotted pin and groove connection or the like, thus holding the light fixture in place.

[0003] However, once installed, accessibility to the retaining clips or torsion springs is often limited, sometimes even requiring the removal of adjacent ceiling or wall panels, or parts ceiling or wall. This makes it difficult to install these lighting assemblies, and also difficult to maintain and uninstall them. It is therefore advantageous to provide a luminaire with an improved release mechanism to ease installation, maintenance and repair without the need to remove the entire lighting assembly and without the need to remove neighbouring infrastructure, and which has less parts and is easier to manufacture.

[0004] It is an object of the invention to alleviate or mitigate at least one or more of the aforementioned problems.

BRIEF SUMMARY OF THE DISCLOSURE

[0005] In accordance with the present invention there is provided a luminaire and a kit of components suitable for assembling the luminaire in accordance with the appended claims.

[0006] According to an aspect, there is provided a luminaire comprising a light fixture assembly. The light fixture assembly comprises a first fixture member having a central axis and at least one first contact surface. The first fixture member is operatively couplable to a ceiling or wall. The light fixture assembly also comprises a second fixture member having at least one second contact surface, the second fixture member configured to operably retain a light source. The light fixture member further comprises a magnetic fastener adapted to provide an attracting force between the first fixture member and the second fixture member. The first fixture member is adapted to matingly receive and releasably affix the second fixture member utilising the magnetic fastener.

[0007] In this way, the first fixture member that is operatively couplable to a ceiling or wall and the second fixture member operably retaining a light source are coupled to one another in a releasable manner. Using a magnetic fastener aids the installation and uninstallation of the luminaire, and also benefits the user's maintenance of the luminaire. More specifically, the magnetic fastener provides a non-permanent coupling between the first fixture member and the second fixture member, yet provides a sufficient magnetic force of attraction to secure the second fixture member to the first fixture member.

[0008] Being non-permanent, the user can decouple the first and second fixture members to, for example, remove the second fixture member to replace the light source. For example, the user may apply an external force to the second fixture member or provide a rotational force in order to overcome the magnetic force of attraction and release the second fixture member from the first fixture member.

[0009] Further, the present invention provides an advantage whereby the entire luminaire assembly does not need to be removed to facilitate maintenance and repair after its initial installation, such as in the case with previously known luminaires where access to the release mechanism is inhibited, or is at least indirect.

[0010] In certain embodiments, the light fixture assembly is a recessed light fixture assembly.

[0011] In certain embodiments, the first fixture member is configured to fixedly engage with the ceiling or wall.

[0012] Thus, the light fixture does not protrude from the surface of the ceiling or wall, increasing usable space in the room and improving light coverage by having the light source closer to the wall or ceiling, while retaining the benefit of the magnetic fastener release mechanism.

[0013] Alternatively, the light fixture assembly is a pendant light fixture assembly. A pendant light fixture assembly suspends from the ceiling or wall, providing an advantage of improved access to the light fixture and its release mechanism.

[0014] In certain embodiments, the first contact surface of the first fixture member is arranged so as to face in a direction that is substantially parallel to the central axis of the first fixture member.

[0015] In certain embodiments, the at least one first contact surface of the first fixture member is arranged so as to face in a direction that is substantially perpendicular to the central axis of the first fixture member.

[0016] In certain embodiments, the at least one second contact surface of the second fixture member is arranged so as to operatively face in a mating direction of the first contact surface [0017] In certain embodiments, the magnetic fastener comprises at least one magnetic element and at least one ferromagnetic element. The at least one magnetic element and the at least one ferromagnetic element are cooperatively arranged on the at least one first contact surface and the at least one second contact surface.

[0018] By having at least one magnetic element and at least one ferromagnetic element cooperatively arranged on the at least one first contact surface and the at least one second contact surface, the magnetic and ferromagnetic element(s) attract one another to magnetically couple the first contact surface and the second contact surface.

[0019] In certain embodiments, the at least one magnetic element is provided on the at least one first contact surface of the first fixture member, and the at least one ferromagnetic element is provided on the at least one second contact surface of the second fixture member.

[0020] Alternatively, the at least one magnetic element is provided on the at least one second contact surface of the second fixture member, and the at least one ferromagnetic element is provided on the at least one first contact surface of the first fixture member.

[0021] In certain embodiments, the at least one magnetic element is a single element formed congruent with the first contact surface.

[0022] In certain embodiments, the at least one magnetic element is a single element formed congruent with the second contact surface.

[0023] In certain embodiments, the at least one magnetic element is a single element formed congruent with the first contact surface and the second contact surface.

[0024] By having a single magnetic element formed congruent with the first contact surface and/or the second contact surface, the magnetic element covers the whole contact surface in a continuous manner. In this way, the effective surface area for magnetic interaction between the first contact surface and the second contact surface is maximised so that the first and second fixture members can be coupled together regardless of their rotational orientation relative to each other. That is, there is no required predetermined rotational orientation for the magnetic elements to align and affix the second fixture member to the first fixture member.

[0025] In certain embodiments, the ferromagnetic element is an integral part of the first contact surface.

[0026] In certain embodiments, the ferromagnetic element is an integral part of the second contact surface.

[0027] In certain embodiments, the ferromagnetic element is an integral part of the first contact surface and the second contact surface.

[0028] By having a ferromagnetic element as an integral part with the first and/or second contact surface, the number of parts in the luminaire is reduced, simplifying manufacture and reducing manufacture costs. Also, this feature provides an advantage whereby the magnetic element on the reciprocal surface interacts with the ferromagnetic contact surface, which removes the need to precisely align the magnetic and ferromagnetic elements. Overall, this reduces the complexity of actuating the magnetic fastener mechanism.

[0029] In certain embodiments, the first contact surface is provided on a bezel of the first fixture member.

[0030] In certain embodiments, the second contact surface is provided on a flange portion of the second fixture member.

[0031] In certain embodiments, the luminaire further comprises a stopping member adapted to prevent rotation of the second fixture relative to the first fixture member about the central axis of the first fixture member.

[0032] Thus, the stopping member prevents the second fixture member from rotating relative to the first fixture member, providing a secure but non-permanent magnetic coupling between the first fixture member and the second fixture member. Advantageously, the stopping member also keeps the fixture members, specifically the magnetic and ferromagnetic elements, in alignment.

[0033] In certain embodiments, the stopping member is configured to provide a predetermined orientation of the second fixture member with respect to the first fixture member.

[0034] By having a stopping member configured to provide a predetermined orientation of the second fixture member with respect to the first fixture member, the second fixture member will only affix to the first fixture member in said predetermined orientation. This is particularly advantageous since it allows the luminaire to be installed in a predetermined manner. Also, this feature provides a benefit whereby the user can first position the second fixture member in proximity to the first fixture member in an orientation such that the magnetic elements and the ferromagnetic elements are out of alignment, and then rotate the second fixture member about its central axis such that the magnetic elements and ferromagnetic elements align and affix the second fixture member to the first fixture member.

Still further, the second fixture member can be released by rotating its central axis to place the magnetic and ferromagnetic elements out of alignment.

[0035] In certain embodiments, the light source is a light bulb. [0036] Alternatively, the light source is a light-emitting diode (LED).

[0037] In certain embodiments, the light source is an organic light-emitting diode (OLED).

[0038] According to a further aspect there is provided a kit of components suitable for assembling a luminaire according to the aspects and embodiments of the invention as claimed with the appended claims.

DETAILED DESCRIPTION

[0040] Like reference numerals are used to depict like features throughout [0041] Figure 1A illustrates a sectional view of a luminaire assembly. The luminaire assembly 10 comprises a light fixture assembly for fixing into a ceiling 12. The light fixture assembly comprises a first fixture member 14 that is fitted through an opening of the ceiling 12 such that a longitudinal portion 14a of the first fixture member 14 is retained in the ceiling 12 by retention clips 24. In this embodiment, the first fixture member 14 is coupled to a ceiling by retention clips 24, however it envisaged that the coupling can be enabled by other means such as spring clips or hooks, and it is further envisaged that the first fixture member 14 can be coupled to a wall. A bezel portion 14b and a lip portion 14c of the first fixture member 14 are disposed downward of the ceiling 12. The first fixture member 14 has a central axis 26 in a direction normal to the ceiling 12 surface. The bezel portion 14b of the first fixture member 14 forms a shoulder with the longitudinal portion 14a and extends outward away from the central axis 26 such that the bezel portion 14b is parallel with and in flush contact with the surface of the ceiling 12. Similarly, the lip portion 14c forms a shoulder with the bezel portion 14b. This configuration allows a flange portion 16b of a second fixture member 16 to be matingly received against the bezel 14b and lip portions 14c of the first fixture member 14.

[0042] The second fixture member 16 also has a longitudinal portion 16a parallel with and received in the longitudinal portion 14a of the first fixture member 14. The second fixture member 16 houses a gimbal fixture 30 that is configured to retain light source 18. In the depicted embodiment, the light source is a light-emitting diode (LED). However it should be appreciated that the light-emitting diode can be other suitable light sources in accordance with the present disclosure, such as a light bulb or an organic light-emitting diode (OLED). The longitudinal portion 16a of the second fixture member 16 houses a heat sink 28 that is configured to absorb heat, taking the heat away from the light source 18.

[0043] The light fixture assembly further comprises a magnetic fastener mechanism to provide an attracting force between the first fixture member 14 and the second fixture member 16. More specifically, the bezel portion 14b of the first fixture member 14 and the flange portion 16b of the second fixture member 16 are magnetically coupled to one another in a releasable manner by a magnetic fastener mechanism. The magnetic fastener mechanism involves ferromagnetic elements 22 located on the surface of the bezel portion 14b and magnetic elements 20 located on the upper surface of the flange portion 16b. The ferromagnetic elements 22 and the magnetic elements 20 magnetically attract one another such that the second fixture member 16 is matingly received in and releasably affixed to the first fixture member 14. In this embodiment, ferromagnetic elements 22 are located on the surface of the bezel portion 14b and magnetic elements 20 are located on the surface of the flange portion 16b, however it should be appreciated that ferromagnetic elements 22 can be located on the upper surface of the flange portion 16b and magnetic elements 20 can be arranged on the surface of the bezel portion 14b, and it should further be appreciated that the ferromagnetic elements 22 and magnetic elements 20 can be located inside or integral with the flange 16b and bezel 14b portions. The magnetic fastener elements 20, 22 are arranged in a way as to face in a direction substantially parallel to the central axis 26 of the first fixture member 14.

[0044] Figure 1B illustrates a luminaire assembly with an alternate magnetic fastener configuration to that of Figure 1A. The lip portion 114c of the first fixture member 114 and the flange portion 116b of the second fixture member 16 are magnetically coupled to one another in a releasable manner by a magnetic faster mechanism. The magnetic fastener mechanism involves ferromagnetic elements 122 located on a surface of the lip portion 114c and magnetic elements 120 located on the outer surface of the flange portion 116b. The ferromagnetic elements 122 and the magnetic elements 120 magnetically attract one another such that the second fixture member 116 is matingly received in and releasably affixed to the first fixture member 114. In this embodiment, ferromagnetic elements 122 are located on the surface of the lip portion 114c and magnetic elements 120 are located on the surface of the flange portion 116b, however it should be appreciated that ferromagnetic elements 122 can be located on the outer surface of the flange portion 116b and magnetic elements 120 can be arranged on the surface of the lip portion 114c, and it should further be appreciated that the ferromagnetic elements 122 and magnetic elements 120 can be located inside or integral with the flange 116b and bezel 114b portions. The magnetic fastener elements 120, 122 are arranged in a way as to face in a direction substantially perpendicular to the central axis 126 of the first fixture member 114.

[0045] Figure 2A illustrates a luminaire assembly with a further alternate magnetic fastener configuration to that of Figure 1A and 1B. The longitudinal portion 214a of the first fixture member 214 and the longitudinal portion 216a of the second fixture member 216 are magnetically coupled to one another in a releasable manner by a magnetic fastener mechanism. The magnetic fastener mechanism involves ferromagnetic elements 222 located on the surface of the first fixture longitudinal portion 214a and magnetic elements 220 located on the surface of second fixture longitudinal portion 216a. The ferromagnetic elements 222 and the magnetic elements 220 magnetically attract one another such that the second fixture member 216 is matingly received in and releasably affixed to the first fixture member 214. In this embodiment, ferromagnetic elements 222 are located on the surface of the first fixture longitudinal portion 214a and magnetic elements 220 are located on the second fixture longitudinal portion 216a, however it should be appreciated that ferromagnetic elements 222 can be located on the surface of the second fixture longitudinal portion 216a and magnetic elements 220 can be arranged on the surface of the first fixture longitudinal portion 214a, and it should further be appreciated that the ferromagnetic elements 222 and magnetic elements 220 can be located inside or integral with the longitudinal portions 214a, 216a. The magnetic fastener elements 220, 222 are arranged in a way as to face in a direction substantially perpendicular to the central axis 226 of the first fixture member 214.

[0046] Figure 2B illustrates a luminaire assembly with a yet further alternate magnetic fastener configuration that of Figures 1A, 13 and 2A. The bezel portion 314b and the lip portion 314c of the first fixture member 314 are magnetically coupled to the second fixture member 314 in a releasable manner by a magnetic fastener mechanism. The magnetic fastener mechanism involves firstly, ferromagnetic elements 322 located on the shoulder connecting the bezel portion 314b and the lip portion 314c and secondly, magnetic elements 320 located on an upper outward surface of the flange portion 316b. The ferromagnetic elements 322 and the magnetic elements 320 magnetically attract one another such that the second fixture member 316 is matingly received in and releasably affixed to the first fixture member 314. In this embodiment, ferromagnetic elements 322 are located on the shoulder connecting the bezel portion 314b and the lip portion 314c, and magnetic elements 320 are located on an upper outward surface of the flange portion 316b, however it should be appreciated that ferromagnetic elements 322 can be located on an upper outward surface of the flange portion 316b and magnetic elements 320 can be arranged on the shoulder connecting the bezel portion 314b and the lip portion 314c, and it should further be appreciated that the ferromagnetic elements 322 and magnetic elements 320 can be located inside or integral with the flange portion 316b and inside the shoulder connecting the bezel portion 314b and the lip portion 314. The magnetic fastener elements 320, 322 arranged in this way provide an attracting force in directions both substantially parallel and perpendicular to the central axis 326 of the first fixture member 314.

[0047] Figure 3A illustrates a luminaire assembly with a configuration substantially the same as in Figure 1A. However, rather than the luminaire assembly being recessed in the ceiling as in Figures 1A-2B, the luminaire assembly in Figure 3A is a pendant light assembly 400 suspended from a ceiling 438. A ceiling canopy 436 is mounted to the ceiling. The first fixture member 414 further comprises an end section 414d with an integrated holder 432 configured to connect pendant tubing 434 between the holder 432 and the ceiling canopy 436. The pendant tubing 434 houses electrical wiring (not shown). Similarly, Figures 33, 4A and 4B illustrate a pendant light assembly having a configuration substantially the same as in Figures 1B, 2A and 2B respectively.

[0048] Figure 5A illustrates a plan view of the first fixture member having a configuration substantially the same as in Figure 1A. The first fixture member 14 comprises a longitudinal portion 14a, a bezel portion 14b and a lip portion 14c. Each of the sections 14a, 14b, 14c are concentric with one another and share a common central axis 26, as better seen in the previous Figures, for example in Figure 1A. The longitudinal portion 14a is radially displaced from the central axis and has a relatively thin wall thickness. As previously seen in Figure 1A, the bezel portion 14b forms a shoulder with the longitudinal portion 14a, radially displacing the bezel portion 14b outward from the longitudinal portion 14a. Similarly, the lip portion 14c forms a shoulder with the bezel portion 14b, displacing the lip portion 14c further outward from the central axis 26. A number of ferromagnetic elements 22 are contained in the bezel portion 14b of the first fixture member 14. In this embodiment, four circular ferromagnetic elements 22 are located on a surface of the bezel portion 14b, each ferromagnetic element 22 is equidistant from the central axis 26 and is displaced 90° from the next ferromagnetic element 22. However, it should be appreciated that any number of ferromagnetic elements 22 having non-circular profiles can be located in or on the bezel portion 14b in a number of orientations according to the present disclosure. For example, two ferromagnetic elements 22 having a square profile can be positioned 180° from each other in the bezel portion 14b.

[0049] Figure 5B illustrates a plan view of the first fixture member. A single ferromagnetic element 22 is contained in the bezel portion 14b of the first fixture member 14. The single ferromagnetic element 22 is on the surface of the bezel portion 14b and forms a continuous ring on the bezel portion 14b in this embodiment, however it is envisaged that the ferromagnetic element 22 can be congruent with the bezel portion 14b or it can be contained within the surface of the bezel portion 14b.

The ferromagnetic elements 122 are generally longitudinal and have a profile that follows the curvature of the lip portion 114c. In this embodiment, four ferromagnetic elements 122 are located within the surface of the lip portion 114c, each ferromagnetic element 122 is equidistant from the central axis 126 and is displaced 900 from the next ferromagnetic element 122. However, it should be appreciated that any number of ferromagnetic elements 122 can be located in or on the surface of the lip portion 114c in a number of orientations according to the present disclosure. For example, two ferromagnetic elements 122 having a generally longitudinal profile following the curvature of the lip portion 114c can be positioned 1800 from each other.

[0051] Figure 50 illustrates a plan view of the first fixture member. A single ferromagnetic element 122 is located on the surface of the lip portion 114c. The single ferromagnetic element 122 forms a continuous ring on the lip portion 114c. In this embodiment, the single ferromagnetic element 122 is located on the surface of the lip portion 114c, however it should be appreciated that the ferromagnetic element 122 can be congruent with the lip portion 114c or it can be contained within the surface of the lip portion 114c.

[0052] Figure 6A illustrates a plan view of the second fixture member having a configuration substantially the same as in Figure 1A. The second fixture member 16 comprises a longitudinal portion 16a and a flange portion 16b that are concentric with one another and share a common central axis 26, as better seen in Figure 1A. The longitudinal portion 16a is radially displaced from the central axis, having a relatively thin wall thickness, and is configured to retain a light source 18. The flange portion 16b is radially displaced outward from the longitudinal portion 16a. A number of magnetic elements 20 are contained in the flange portion 16b of the second fixture member 16. In this embodiment, four circular magnetic elements 20 are located on a surface of the flange portion 16b, each magnetic element 20 is equidistant from the central axis 26 and is displaced 90° from the next magnetic element 20. However, it should be appreciated that any number of magnetic elements 20 having non-circular profiles can be located in or on the flange portion 16b in a number of orientations according to the present disclosure. For example, two magnetic elements 20 having a square profile can be positioned 180° from each other in the flange portion 16b.

[0053] Figure 6B illustrates a plan view of the second fixture member. A single magnetic element 20 is contained in the flange portion 16b of the second fixture member 14. The single magnetic element 20 is on the surface of the flange portion 16b and forms a continuous ring on the flange portion 16b in this embodiment, however it is envisaged that the magnetic element 22 can be congruent with the flange portion 16b or it can be contained within the surface of the flange portion 16b.

[0054] Figure 6C illustrates a plan view of an alternate second fixture member having a configuration substantially the same as in Figure 1B. In this embodiment, four magnetic elements 120 are located within a surface of the flange portion 116b, each magnetic element is equidistant from the central axis 126 and is displaced 90° from the next magnetic element 120. The magnetic elements 120 are generally longitudinal and have a profile that follows the curvature of the flange portion 116b. In this embodiment, four magnetic elements 120 are located within the surface of the flange portion 116b, each magnetic element 120 is equidistant from the central axis 126 and is displaced 90° from the next magnetic element 120. However, it should be appreciated that any number of magnetic elements 120 can be located in or on the surface of the flange portion 116b in a number of orientations according to the present disclosure. For example, two magnetic elements 120 having a generally longitudinal profile following the curvature of the flange portion 116b can be positioned 180° from each other.

[0055] Figure 6D illustrates a plan view of the second fixture member. A single magnetic element 120 is located within a surface of the flange portion 116b. The single magnetic element 120 forms a continuous ring in the flange portion 116b. In this embodiment, the single magnetic element 120 is located within the surface of the flange portion 116b, however it should be appreciated that the magnetic element 120 can be congruent with the flange portion 116b or it can be located on the surface of the flange portion 116b.

[0056] Figure 7A illustrates a plan view of a mounting system for a luminaire assembly according to an embodiment of the present invention in the configuration as illustrated in Figure 1B. The mounting system comprises a second fixture member 116 configured to retain a light source 118. Four magnetic elements 120 are located within a surface of the flange portion 116b, each magnetic element 120 is equidistant from the central axis 126 and is displaced 90° from the next magnetic element 120. The magnetic elements 120 are generally longitudinal and have a profile that follows the curvature of the lip portion 114c.The mounting system also comprises a first fixture member 114 having four ferromagnetic elements 122. The four ferromagnetic elements 122 are located within a surface of the lip portion 114c, each ferromagnetic element 122 is equidistant from the central axis 126 and is displaced 90° from the next ferromagnetic element 122. The ferromagnetic elements 122 are generally longitudinal and have a profile that follows the curvature of the lip portion 114c. In this embodiment, the magnetic elements 120 are located on the second fixture member 116 and the ferromagnetic elements are located on the first fixture member 114, however it should be appreciated that the magnetic elements 120 can be located on the first fixture member 114 and the ferromagnetic elements 122 can be located on the second fixture member 116 according to the present disclosure.

[0057] The first fixture member 114 and the second fixture member 116 share a common central axis 126 about which the second fixture member 116 is rotatable. In this embodiment, the second fixture member 116 is rotated about the central axis 126 such that the magnetic elements 120 on the second fixture member 116 and the ferromagnetic elements 122 on the first fixture member 114 are aligned. The alignment of the magnetic elements 120 and the ferromagnetic elements 122 magnetically couple the first fixture member 114 and the second fixture member 116. In this way, the second fixture is affixed to the first fixture member 114 in a releasable manner. By rotating the second fixture member 116 about the central axis to separate the magnetic elements 120 and the ferromagnetic elements 122, the second fixture member 116 can be released from the first fixture member 114. The mounting system for the luminaire assembly in a non-magnetically coupled state is shown in Figure 7B.

[0058] Figure 7C illustrates a plan view of a mounting system for a luminaire assembly according to an embodiment of the present invention having a single ferromagnetic element 122 located on the lip portion 114c and a single magnetic element 120 located within a surface of the flange portion 116b. Having a single continuous ferromagnetic element 122 and a single continuous magnetic element 120 allows the first fixture member 114 and the second fixture member 116 to be magnetically coupled together without the need to align the ferromagnetic elements 122 and the magnetic elements 120. Thus, there is no predetermined orientation by which the fixture members 114, 116 are affixed together. It is further envisaged that the mounting system can further comprise a stopping member that is used to prevent rotation of the second fixture member 116 about the central axis 126 about the first fixture member 114 once the fixture members 114, 116 are magnetically coupled together. This can take the form of a reciprocating flange and recess located on or integral with the fixture members 114, 116 that prevent relative rotation of the fixture members 114, 116. In this embodiment, the single magnetic element 120 is located on the second fixture member 116 and the single ferromagnetic element 122 is located on the first fixture member 114, however it should be appreciated that the single magnetic element 120 can be located on the first fixture member 114 and the single ferromagnetic element 122 can be located on the second fixture member 116 according to the present disclosure.

[0059] Figure 8 illustrates a plan view of a mounting system for a luminaire assembly. The second fixture member houses a gimbal fixture 230 that is configured to retain light source 218 such as a light-emitting diode (LED). The gimbal fixture 230 is configured to tilt, which in turn tilts the light source 218, allowing light from the light source 218 to be directed over a larger range. The tilting of the gimbal fixture 230 is separate from the rotation of the second fixture member 216 about the central axis 226. The orientation of the magnetic elements 220 and ferromagnetic elements 222 are not affected by the tilting of the gimbal fixture 230.

[0060] Figure 9 illustrates a section view of a luminaire assembly having a configuration substantially the same as in Figure 2B. However, the light source 318 and the gimbal fixture 330 retaining the light source 318 are recessed a distance into the longitudinal section 316a of the second fixture member 316.

[0061] The present invention also includes a kit of components suitable for assembling the luminaire according to any of the previously described embodiments. The kit of components may include at least one each of the following: a light fixture assembly, a first fixture member, a second fixture member, and a magnetic fastener. More specifically, the kit of components comprises: a first fixture member having a central axis and at least one first contact surface, said first fixture member is operatively couplable to a ceiling or wall; a second fixture member having at least one second contact surface, configured to operably retain a light source; and a magnetic fastener, adapted to provide an attracting force between said first fixture member and said second fixture member, wherein said first fixture member is further adapted to matingly receive and releasably affix said second fixture member utilising said magnetic fastener.

[0062] Various modifications to the detailed designs are described above are envisaged.

For example, the ferromagnetic elements described in the previous embodiments can be replaced by a ferrous element.

[0063] In certain embodiments, the magnetic and/or the ferromagnetic element(s) may be provided in the form of a flexible tape.
