Description

Technical field

[0001] The present invention is developed in the technical field of interior lighting, and in particular it relates to a recessed lighting appliance, in accordance with the preamble of claim 1.State of the art

[0002] Lighting appliances are known in the art, such as for example spotlights, which can be mounted inside a wall, such as for example a false ceiling. Usually, such appliances are installed in the wall without protruding therefrom (so-called "flush" installation), or protruding by a minimum length.

[0003] In detail, the aforesaid lighting appliances provide in their front part, a support structure, with a concave element and a rotatable support, rotatably mounted to the concave element. The edge of the concave element is usually placed flush with the wall, so that the concavity recesses towards the inside of the wall.

[0004] Behind the concavity, i.e. inside the false ceiling, the rear part of the appliance is placed. For example, such parts of the appliance placed behind the concavity are a lighting assembly with a heatsink, and to them can be connected other components such as electronics and power and / or signal wiring. The lighting assembly comprises a lighting element that is visible through a central hole of the concave element.

[0005] The rear elements, therefore, once the appliance is recessed, are hidden from view while the front part of the appliance is the one visible to the user.

[0006] Lighting appliances are also known in which the lighting assembly is rotatable to change the orientation of the light beam, i.e., so that the light beam is no longer perpendicular to the wall in which it is installed but is actually inclined.

[0007] In this case, the support structure of the spotlight remains fixed to the wall, while the lighting assembly rotates with respect to it.

[0008] An example of a lighting appliance having a rotatable lighting assembly is shown in document JP 6405340 B2.Problem of the prior art

[0009] With the rotation of the lighting assembly, spaces open up between the lighting element and the hole of the concave element. Consequently, components behind the optical assembly, such as the heatsink, cables, terminals, etc., which are usually aesthetically unpleasant, can potentially become visible again.

[0010] In some prior art appliances, to overcome this problem a membrane is fixed between the concave element and the lighting assembly. With the rotation of the lighting assembly, the membrane stretches and keeps the rear parts hidden. However, usually in these solutions the membrane is only suitable for small inclinations of the lighting assembly, and therefore the functionality of the spotlight is limited.

[0011] In other prior art appliances, for example the one shown in document JP 6405340 B2, the entire structure of the lighting appliance is shaped in a way that, by rotating the lighting assembly, the view of the components behind it is prevented or limited. However, these devices involve high manufacturing and design costs, as the entire apparatus must be shaped and specifically designed in advance, also taking into account the recess in which it will be installed. By way of example, the appliance of JP 6405340 B2 requires the provision of a fixed cover element, formed in the support structure, suitable for concealing the environment behind the lighting assembly on a side opposite to that of rotation. Furthermore, this appliance requires the formation of a sliding portion between the heatsink and the support structure, which is provided with specific guides along which a cover panel can slide during the rotation of the lighting assembly. It is therefore evident that the appliance of the aforesaid document needs to provide a priori a panel and respective guides on one side of the lighting assembly, and a cover element on the opposite side.Summary of the invention

[0012] The object of the present invention is to solve the drawbacks mentioned in reference to the prior art, and in particular to provide a tiltable recessed lighting appliance in which the rear parts remain hidden, without limiting the functionality of the spotlight or the freedom of its design.

[0013] This and other objects are achieved by a recessed lighting appliance according to any one of the appended claims.

[0014] The lighting appliance of the invention provides a support structure, and a lighting assembly connected to the support structure and rotatable with respect to it. One or more cover flaps each have two end portions and a panel interposed between them. During the rotation of the lighting assembly with respect to the support structure, the first end portion remains constrained to the support structure, while the second end portion is constrained to move along the lighting assembly towards and away from the support structure. The panel of each flap, in a respective inclination of the lighting assembly, visually occupies a free space between the lighting element and the edge of the hole of the concave element.

[0015] Advantageously, the panel of each cover flap can follow the rotational movements of the lighting assembly, remaining positioned along the lighting assembly so as to effectively cover the rear components, and without flapping freely. Moreover, the cover flaps can be either pre-installed on the spotlight, so as not to require being fixed at the time of installation of the lighting appliance in the wall, or during installation, as needed.

[0016] Further features and advantages of the invention will be recognizable by a person skilled in the art from the following detailed description of exemplary embodiments of the invention.Brief description of the figures

DETAILED DESCRIPTION

[0018] With reference to the accompanying drawings, a recessed lighting appliance according to the present description is indicated as a whole by the number 1.

[0019] The lighting appliance 1 comprises a lighting assembly 2 and a support structure 3, operatively associated with the lighting assembly 2.

[0020] The lighting assembly 2 and the support structure 3 are spaced from each other in a direction of a symmetry or central axis X-X.

[0021] In particular, the lighting assembly 2 and the support structure 3 are mechanically and electrically connected according to known techniques and therefore not described.

[0022] The support structure 3 is configured for recessed mounting in a wall of a building, which can be indifferently a wall of masonry, wood, plasterboard or other materials or in a false ceiling of a wall. The false ceiling can also be of masonry, wood, plasterboard or other materials.

[0023] It is also worth noting that the wall (and therefore also its relative false ceiling) can be the ceiling and / or the perimeter walls of a building.

[0024] The lighting assembly 2 is generally positioned behind the support structure 3, and can be housed in a cavity of the wall (or of the false ceiling) or at least partly behind the wall. The wall (not shown) has a hole, generally circular, quadrangular or of different shapes, for the recess of the lighting appliance 1.

[0025] The lighting assembly 2 comprises a lighting element 23. Preferably, the lighting assembly 2 in a known manner also comprises a heatsink 21.

[0026] The heatsink 21 in turn comprises a plurality of heatsink elements 211, such as dissipating fins or dissipating pins of various shapes.

[0027] The heatsink elements 211 are arranged so as to define among them a plurality of passages for a flow of air, so as to dissipate heat to the air in the passages by convection.

[0028] In the illustrated embodiments, the heatsink elements 211 protrude from a bottom wall 212, along the direction of the central axis X-X, away from the support structure 3.

[0029] A person skilled in the art may however provide for alternative arrangements, such as for example heatsink elements 211 shaped as discs or other shapes transverse to the central axis X-X, and connected by a central stem.

[0030] The heatsink 21 has a side wall, which can be identified in part or entirely by the heatsink elements 211, and therefore can be discontinuous. Preferably, the side wall has a substantially cylindrical shape, around the central axis X-X.

[0031] The lighting assembly 2 may comprise other components of lesser interest for the invention and already known to those skilled in the art, such as for example one or more connectors for the power supply and / or control of the appliance and for a lighting element 23, which in the figures are represented fixed to the bottom wall 212 of the heatsink 21.

[0032] The support structure 3 has a concave element 31, oriented away from the lighting assembly 2 and configured for various purposes, including conveying a light beam generated by the lighting element 23, to contain glare. When the lighting assembly 2 is in a first position or reference / initial position or straight position, the light beam is directed along the central axis X-X, which is usually perpendicular to the wall in which the lighting appliance 1 is recessed.

[0033] The concave element, or concavity, 31 has a bottom with a hole 311, preferably central, for the passage of light from the lighting element 23, which can be at least partially housed in the central hole 311. The hole 311 is delimited by a perimeter or edge.

[0034] The concavity 31 also has an end edge 312 facing away from the lighting assembly 2, i.e. towards the environment to be illuminated. The end edge 312 is spaced from the hole 311 in the direction of the symmetry axis X-X.

[0035] The hole 311 and the end edge 312 extend around the axis X-X. Preferably, the end edge 312 is planar, for example circular (as in figures 2-15) or rectangular / square (as in figure 1).

[0036] The end edge 312 preferably extends in a plane parallel to the wall in which the lighting appliance 1 is recessed, which can be the plane in which a surface of the wall lies, or a more internal or more external plane.

[0037] In addition to the concave element 31, which is generally fixed to the wall, the support structure 3 may comprise a rotatable support 33, which is rotatable with respect to the concave element 31 around the axis X-X.

[0038] The lighting assembly 2 is rotatable with respect to the support structure 3 around an inclination axis Y-Y, transverse, preferably perpendicular, to the axis X-X.

[0039] In the illustrated embodiments, this is obtained by means of complementary arcuate surfaces of the support 3 and of the lighting assembly 2, and other connection members known to those skilled in the art.

[0040] Preferably, the lighting assembly 2 is mounted on the rotatable support 33, in such a way as to be rotatable, together with the rotatable support 33 itself, with respect to the concave element 31, around the axis X-X. This therefore allows the lighting assembly 2 to rotate both around the axis X-X and around the inclination axis Y-Y. Hereinafter, reference will be made to a first and a second side of the support 3 and of the lighting assembly 2. The two sides are spaced from each other in a transverse direction Z-Z with respect to the central axis X-X and the inclination axis Y-Y.

[0041] The rotation of the lighting assembly 2 around the inclination axis Y-Y is comprised between at least two predetermined inclinations, which preferably define a first position, or straight position, and at least a second position, or inclined position.

[0042] In the embodiments illustrated in figures 2-10, the lighting assembly 2 is rotatable only in the aforesaid positions. Therefore, by rotating away from the inclined position, the lighting assembly 2 cannot pass the first position. Therefore, the rotation is not symmetrical with respect to the first position, and also the complementary arcuate surfaces of the lighting assembly 2 and of the support 3 can be asymmetrical on the two sides.

[0043] On the first side, in the second position the end edge 312 of the front concavity 31 is closer to the heatsink 21 than in the straight position. On the second side, the end edge 312 is farther from the heatsink 21 than in the straight position. In other words, with the rotation from the first position to the inclined position, the first side of the lighting assembly 2 approaches the end edge 312, while the second side moves away from it.

[0044] Alternative embodiments may however be contemplated, shown for example in figures 11-15, in which the rotation of the lighting assembly 2 is comprised between three predetermined inclinations, which preferably define a first position, or straight position, a second position, or first inclined position, and a third position, or second inclined position, opposite to the first inclined position. The second and third inclinations are preferably symmetrical with respect to the central axis X-X, and therefore the straight position is halfway between the first and the second inclined position.

[0045] That is to say, in the first inclined position, the end edge 312 is closer to the heatsink 21 than in the straight position and in the second inclined position on the first side, while it is more distant from the heatsink 21 than in the straight position and in the second inclined position on the second side. Conversely, in the second inclined position, the end edge 312 is closer to the heatsink 21 than in the straight position and in the first inclined position on the second side, while it is more distant from the heatsink 21 on the first side than in the other two positions.

[0046] In such embodiments, the complementary arcuate surfaces of the lighting assembly 2 and of the support 3 are symmetrical on both sides. The lighting assembly 2 is therefore rotatable indifferently in the two inclined positions according to requirements.

[0047] It should be noted that embodiments, not illustrated, can also be contemplated, in which the lighting assembly 2 is rotatable in the two inclined positions, which are however asymmetrical with respect to the central axis X-X.

[0048] The central hole 311 is shaped in such a way that the lighting element 23 can emit a light beam through the hole 311 in the predetermined inclinations.

[0049] In particular, in the embodiments of figures 2-10, the perimeter of the hole has a first edge portion which is close to the lighting element 23 in the first inclination and spaced from the lighting element 23 in the second inclination, and a second edge portion which is spaced from the lighting element 23 in the first inclination and close to the lighting element 23 in the second inclination.

[0050] In other words, with the rotation of the lighting assembly 2 from the first to the second inclination, the lighting element 23 moves from the first edge portion towards the second edge portion, and vice versa in the reverse movement. Therefore, in both inclinations, a free space is left between the lighting element 23 and the perimeter of the hole, and in particular a first free space in the first inclination, between the lighting element 23 and the second edge portion, and a second free space in the second inclination, between the lighting element 23 and the first hole portion.

[0051] In the embodiment of figures11-15, the perimeter of the hole has a first edge portion and a second edge portion at least partially spaced from the lighting element 23 in the straight position.

[0052] Preferably, the lighting element 23 in the straight position is spaced substantially by the same amount from the first and second edge portions.

[0053] Alternatively, one of the two edge portions may be closer to the lighting element 23 in the straight position than the other edge portion.

[0054] In the first inclined position, the first edge portion is close to the lighting element 23, while the second edge portion is spaced from it. In the second inclined position, the first edge portion is spaced from the lighting element 23 while the second edge portion is close to it. In other words, with the rotation of the lighting assembly 2 from the straight position, in which the lighting element is at least partially spaced from the first and second edge portions, to the first inclined position, the lighting element 23 moves towards the first edge portion away from the second edge portion, and vice versa in the movement towards the second inclined position. Therefore, in all inclinations, a free space is substantially left between the lighting element 23 and the perimeter of the hole.

[0055] The invention provides that the lighting appliance 1 comprises at least one cover flap 4 to cover rear elements to the lighting assembly 2, in at least one of the predetermined inclinations, in particular at least when the lighting assembly 2 is in an inclined position.

[0056] In all the illustrated embodiments, two cover flaps 4 are represented along the first side and the second side of the lighting assembly 2, in particular of the heatsink 21. The flaps 4, therefore, are spaced from each other in the transverse direction Z-Z. Embodiments with a single flap 4 may however be provided, especially corresponding to the second side, which is the one most visually exposed in the inclined position of the embodiments illustrated in figures 1-10.

[0057] In the following, some features of a cover flap 4 will be described, which are to be understood as applicable to each flap 4.

[0058] The flap 4 has a first end portion 41, a second end portion 42, and a panel 43. In the first position (or reference position), the first and second end portions 41, 42 are spaced at least in the direction of the central axis X-X. The panel 43 extends between the two end portions 41, 42 and is configured to visually occupy a respective free space between the lighting element 23 and the hole edge, in a respective one of the predetermined inclinations.

[0059] Thus, an observer looking at the free space from the side of the concavity of the concave element 31 will see a cover flap behind the free space, and this flap 4 will prevent the view of disordered components at the rear. In each of the inclinations, there will be a different free space visually occupied by a different flap 4, which will be suitably inclined transversely to the line of observation thanks to the base constraints of its ends 41, 42.

[0060] Preferably, the panel 43 is shaped to partially wrap around the respective side of the lighting assembly 2, in particular of the heatsink 21, along its side wall. For this purpose, the panel 43 may have an arcuate shape, with a concavity facing towards the lighting assembly 2, in particular the heatsink 21. It is not necessary, however, for the panel 43 to be in contact with the heatsink 21.

[0061] The first end portion 41 of the flap 4 is constrained to the support structure 3, in particular to the rotatable support 33. In the illustrated embodiments, for this purpose the first end portion 41 of each flap 4 is rotatably connected to the support structure 3 at a respective hinge element 32. In particular, the flap 4 is rotatable around a respective flap rotation axis parallel to the inclination axis Y-Y.

[0062] Each hinge element 32 can be positioned on a bracket of the support structure 3, in particular on the rotatable support 33, on a rear side opposite to the concave element 31.

[0063] In view of the asymmetrical movement of the lighting assembly 2 of the embodiments of figures 2-10, it is preferable that the hinge element 32 of the first flap 4 is closer to the end edge 312 than the hinge element 32 of the second flap 4. Therefore, the relative brackets may also have different shapes, dimensions and / or positions on the first and second side.

[0064] In the embodiment of figures 11-15, instead, the hinge elements 32 of the two flaps 4 are preferably at the same distance from the end edge 312.

[0065] In other, non-illustrated embodiments, the flap 4, instead of being hinged to the support structure 3 in a fixed or mobile manner, pivoted or with a snap-fit (meaning a hinge that may or may not be subject to translations on the support plane), can be constrained to it according to other modalities, to remain in position during the movement of the lighting assembly 2. For example, the first end portion 41 of the flap 4 may have a hole into which a hook of the support structure 3 is inserted, thus creating a coupling that still allows the retention and rotation of the flap 4.

[0066] The second end portion 42 of the flap 4 is constrained to move along the lighting assembly 2, in particular by sliding along the heatsink 21, precisely along its side wall. More in detail, the second end portion 42 moves towards and away from the support structure 3 during the rotation of the lighting assembly 2 with respect to the support structure 3.

[0067] It should be noted that, in the inclined positions, shown for example in figures 5, 9, 13-14, the second end portion 42 of the flap 4 positioned on the side towards which the lighting assembly 2 is inclined is more spaced from the heatsink 21 than the first end portion 41 along the transverse direction Z-Z.

[0068] In other words, the second end portion 42 of the flap positioned on the side of inclination moves away from the heatsink 21 by effect of gravity, while the first end portion 41, being constrained to the support structure 3, rotates integrally with the lighting assembly 2.

[0069] In the inclined positions, between the heatsink 21 and the flap 4 placed on the side of inclination there is an empty space suitable to allow heat dissipation.

[0070] It should also be noted that the flap 4 positioned on the side opposite to the side of inclination, instead, has a predetermined length such that this flap 4 only partially overlaps, or does not overlap at all, with the heatsink 21.

[0071] This advantageously allows obtaining adequate heat dissipation efficiency even in the inclined positions.

[0072] In the embodiments of figures 1-9 and 11-15, to constrain the movement of the second end portion 42, the lighting assembly 2, in particular the heatsink 21, has at least one guide 213 for each flap 4, and the second end portion 42 is slidable along the respective guide 213. In particular, the guide 213 can be formed in a heatsink element 211, preferably between several heatsink elements 211. For example, two heatsink elements 211 on one side of the heatsink 21 can have respective grooves facing each other, so that the second end portion 42 simultaneously engages both grooves.

[0073] More in detail, the second end portion 42 has a slider 421 shaped to be retained in the guide 213. For greater stability, in the illustrated embodiments there are for each flap 4 two guides 213 and two sliders 421.

[0074] In the embodiments of figures 1-9 and 11-15, the slider 421 has a neck and a head. The head is engaged in the guide 213, while the neck connects the head to the panel 43. The neck is shaped to pass through at least part of one of the passages for the air flow delimited by the two heatsink elements 211 that delimit the guide 213.

[0075] It should be noted that the guide 213 is not necessarily rectilinear, but can be shaped in the most suitable way so that, during the rotation of the lighting assembly 2, the flap 4 inclines and remains resting along the heatsink 21.

[0076] For this purpose, in the embodiments illustrated in figures 1-9, for the guide 213 on the first side, a portion of the guide 213 distal from the support structure 3 is curved with a curvilinear shape towards the lateral surface of the heatsink 21.

[0077] It should also be noted that in the embodiments of figures 1-10, the two flaps 4 are not necessarily symmetrical, but the first flap 4, which covers the first side, can extend away from the support structure 3 (for example, in the straight position, along the direction of the central axis X-X) for a greater length than the second flap 4, which covers the second side.

[0078] It should be noted instead that in the embodiments of figures 11-15, the heatsink 21 is substantially symmetrical with respect to the central axis X-X, and therefore has identical guides 213 on the first and second side.

[0079] Furthermore, the two flaps 4 are substantially symmetrical and extend away from the support structure 3 for the same length.

[0080] To better follow the rotation, in some embodiments, such as in figures 8-9, at least one flap 4, in particular the first flap 4, may comprise two covering bodies 44 connected in rotation to each other. In other words, the panel 43 is divided into the two covering bodies 44. The two covering bodies 44 are constrained to each other at a connection point 45 which is located between the first and second end portions 41, 42 of the flap 4.

[0081] In an alternative embodiment, shown in figure 10, the second end portions 42 of the two flaps 4, although constrained to move along the lighting assembly 2, in particular along the heatsink 21, may not be directly constrained to them. Instead, the lighting appliance 1 comprises a connecting member 5 with two end portions rotatably connected to the second end portions 42 of the two flaps 4. Thus, the connecting member 5 connects the flaps 4 to each other and forms with them and with the support structure 3 (in particular with the rotatable support 33) an articulated quadrilateral. The connecting member 5 can be constrained only to the flaps 4, or also to the lighting assembly 2, in particular to the heatsink 21.

[0082] Therefore, with the rotation of the lighting assembly 2, at least one of the flaps 4 and / or the connecting member 5 can be pushed by the lighting assembly 2, in particular by the heatsink 21, to rotate in turn, so that the flaps remain extended along them and the second end portions 42 move along the heatsink 21, without flapping freely away from it.

[0083] Depending on the length of the flaps 4, it can be provided that the connecting member 5 extends through one or more of the air passages identified by the heatsink elements 211, or that the connecting member 5 is located beyond the heatsink 21 and outside of it, at a greater distance from the support structure 3.

[0084] It should be noted that this configuration can be implemented both in the embodiments with asymmetrical rotation of the lighting assembly 2, i.e. in a single direction with respect to the straight position, and in the embodiments with symmetrical rotation of the lighting assembly 2, i.e. in opposite directions with respect to the straight position.

[0085] Obviously, a person skilled in the art may make numerous equivalent modifications to the variants described above, without thereby departing from the scope of protection defined by the appended claims.
