Definitions

  • suspended ceiling which is positioned a certain distance from the actual ceiling of the building. This is for both cosmetic as well as technical reasons. Providing a space between the concrete or wooden ceiling of a building and a suspended ceiling therefrom, allows for hiding the large number of electrical and telecommunication cables common in modern offices. Additionally, suspended ceilings are useful for such aspects as thermal and sound insulation between floors.
  • a suspended ceiling comprising a plurality of ceiling tiles which are suspended on a grid of supports.
  • This grid has a certain pitch, typically square although of course rectangular is also possible, into which the ceiling tiles are located.
  • the crossed supports have a pitch of approximately 600mm in both directions, thus requiring ceiling tiles with a size of approximately 600mm per side.
  • the gap between the actual ceiling and the suspended ceiling is approximately 150mm. This gap allows for sufficient space in fitting the ceiling tiles and the like, as well for housing any other items to be held in the space.
  • Such lighting tiles typically have the same dimensional size as the ceiling tiles, but further incorporate a number of lighting elements.
  • a common design for such lighting tiles incorporates fluorescent tubes within the lighting tile, these fluorescent tubes being held within louvers to improve the spread of light into the room.
  • Typical lighting tiles are formed with an appropriate recess in which to house the louver and fluorescent tube.
  • the louver and fluorescent tube With the new smaller diameter fluorescent tubes, it is not appropriate to simply scale the size of the louver in a vertical dimension in order to lead to a narrower ceiling tile, as the lighting lamellae present in the louver will cease to be efficient after such scaling. Further, it is desirable to develop a simpler lighting tile with an improved method of fabrication, which is particularly suited for the smaller and lighter louvers useful for the narrow fluorescent tubes.
  • the present disclosure provides a light housing in accordance with independent claim 1, and a method for making the same in accordance with independent claim 6. Further preferred embodiments are given in the dependent claims.
  • the claimed invention can be better understood in view of the embodiments of the light housing and lighting lamellae described hereinafter.
  • the described embodiments describe preferred embodiments of the invention.
  • the attentive reader will note, however, that some aspects of the described embodiments extend beyond the scope of the claims.
  • the described embodiments indeed extend beyond the scope of the claims, the described embodiments are to be considered supplementary background information and do not constitute definitions of the invention per se. This also holds for the subsequent "Brief Description of the Drawings" as well as the "Detailed Description of the Preferred Embodiments.”
  • the recessed portion may be structured as a recessed box extending behind the plane of the front surface, with the open side of the box coinciding with the plane of the front surface. This recessed box would then be closed on the remaining five sides.
  • this light housing would be produced from a single sheet of metal, which is punched out to provide a certain outline, and then bent in order to provide the recessed portion with the five closed sides and an overall footprint the same size as the ceiling tile which it will replace.
  • the light housing will have either a square or rectangular shape, wherein the recessed portion extends between two parallel edges of the light housing.
  • This recessed portion will then provide either a square or rectangular shaped recessed box.
  • the metallic sheet is bent to form two steps, one extending behind the plane of the flat front surface, and the second extending back into this front surface plane. In between the two steps is provided a back surface, which is advantageously parallel with the front flat surface.
  • the steps can either be at right angles, or at any other sloped angle, as long as the same metallic sheet is bent and traverses between the first section of front face to the back surface, and then back to the second section of the front face.
  • the side wings with a trapezoidal shape, wherein the short parallel side is defined as being the width of the back surface of the recessed portion.
  • the long side of the trapezoidal shape can further advantageously be the same length as the sideline of the light housing, such that the side wings extend from the recessed portion all the way out to the side portions of the light housing. By extending all the way out, it is possible to attach the flaps, if present, to the entire side of the flat front surface, which will further improve the strength and rigidity of the light housing.
  • the lighting lamellae with outwardly curving side walls formed by the two side sheets which have a lower portion, in which the separation distance between the two side sheets varies in a linear manner when moving from the vertex toward the two upper edges. Furthermore, in this lower portion the separation between the two side sheets does not alter along the length direction of the lighting lamellae.
  • This lower portion may then lead into an intermediate and upper portions, in which the separation width between the two side sheets varies in a non-linear manner, when moving from the top of lower portion to the two upper edges.
  • This non-linear variation preferably proceeds with a constantly varying radius of curvature. Further, within the intermediate portion the separation distance between the two side sheets does not alter along the length direction of the lighting lamellae.
  • the light housing 10 of the present disclosure is completely structured from this single sheet of material, and is in fact formed into the light housing 10 by means of simply bending and folding the material.
  • metallic sheets 14 are advantageous in this aspect, as metal will readily fold without fracturing, and will generally maintain the folded shape after removal of pressure.
  • plastic materials can also be selectively heated to lead to regions which are readily foldable, and thus a single plastic sheet can be structured into the light housing 10.
  • the intermediate step in production of the light housing 10 is the provision of two steps within the central portion of the material sheet. These two steps are generally provided in opposition, the first step leading to the material being positioned behind the flat front surface 11, so as to create the back surface 16. The second opposing step returns the plane of the material sheet back to the same as the front surface 11, to create a generally planar flat front surface 11 of the light housing 10.
  • a recessed portion 12 is defined. This recessed portion 12 is sized and shaped so as to appropriately house the light fittings 4 of the light housing 10.
  • the recessed portion 12 it is generally preferable for the recessed portion 12 to extend from one side of the material sheet to the other side of the material sheet, to create either a square or rectangular recessed portion 12.
  • the light fittings 4 to be used with the light housing 10 will be square or rectangular in nature, thus necessitating the square or rectangular recessed portion 12. Structuring the recessed portion 12 in this way, allows for the provision of side wings 15 in order to complete the recessed portion 12 and create an open recessed box 13.
  • the side wings 15 are originally formed as part of the flat material sheet which is cut or stamped to the appropriate precursor shape. That is, these side wings 15 are also part of the original material sheet, and do not need to be attached to the light housing 10 after bending to form the recessed portion 12.
  • this pre-forming of the side wings 15, leads to a great reduction in the overheads for fabricating the light housings 10, as only the steps of cutting and bending need to be performed. Whilst this is the preferred form, it is also possible to provide the side wings 15 separate from the original material sheet, and attachable thereto.
  • the side wings 15 can be bent round in order to close in the open two sides of the recessed portion 12.
  • the light housing 10 is provided with the recessed box 13, which is of the appropriate size and shape for housing the desired light fittings 4.
  • the recessed box 13 is provided by the back surface 16, the two sidewalls formed by the steps, as well the sidewalls formed by the bent over side wings 15. It is not necessary to provide the steps at exactly 90°, as shown in Figures 2a and 2b , and indeed the steps can in fact be sloped sections between the material making up the flat front surface 11 and the back surface 16. It is desirable only that the back surface 16 and the flat front surfaces 11 be parallel with each other, so as to reduce the overall depth of the light housing 10.
  • the side wings 15 with attachment flaps 17.
  • These attachment flaps 17 can be provided by additional bent sections of the side wings 15, and are thus also provided as integral parts from the original material sheet. After bending of the side wings 15, the flaps 17 will overlap with the rear side of the flat front surface 11. Such flaps 17 can then be used for attachment of the side wing 15 to the flat front surface 11, which will lead to an improvement in the rigidity of the light housing 10.
  • This attachment may be by welding (preferably spot welding), or gluing.
  • This simple mechanism for structuring the light housing 10 improves not only on the manufacturing overheads, but also reduces waste material.
  • the final light housing 10 is rigid enough to be held within the appropriate hole in the suspended ceiling 1.
  • flaps 17 on the central sections of the long side 19 of the rhombus making up the side wings 15. By providing these additional flaps 17, it is possible to readily hold the light fitting 4 within the recessed box 13. This will then mean that the light housing 10 need not be structured such that the light fitting 4 must be fully attached to the light housing 10. The flaps 17 can be used to hold the light fitting 4 removably in place, thus improving the use of the light housing 10.
  • the light housing 10 It is possible to structure the light housing 10 with a generally reduced thickness, primarily as this is intended to be used with the narrow fluorescent tubing.
  • Typical light housings 10 of the art have a thickness in the region of 45 mm.
  • the light housing 10 of the present disclosure may be provided with a thickness of 40 mm. This is primarily as a result of the use of the narrow diameter fluorescent tubes.
  • these fluorescent tubes have a reduced diameter leading to the reduced thickness of the light housing 10, it is possible to utilise a gap between the suspended ceiling 1 and the concrete ceiling 3 which is much narrower than that currently used. At present, it is typical for the suspended ceiling 1 to be approximately 150 mm away from the concrete or wooden ceiling 3.
  • the narrower diameter fluorescent tubes it is possible to reduce the size of this gap to as little as 100 mm. This clearly has advantages in buildings, as it allows for a higher suspended ceiling 1.
  • the light housing 10 is to be used in a suspended ceiling 1 arrangement which is only 100 mm from the concrete ceiling 3, the provision of the rhombus shaped side wings 15 is advantageous. It is clear that the light housing 10 must be positioned within a hole in the suspended ceiling 1. Typically, this is achieved after the suspended ceiling 1 is in place, at when any maintenance needs to be undertaken to the light housing 10, the light housing 10 must be removable from the suspended ceiling 1. Providing the side wings 15 with the rhombus outline, allows the light housing 10 to be slid within the gap in the suspended ceiling 1, with the suspended ceiling 1 being only 100 mm from the concrete ceiling 3. Obviously, the angled side to the side wings 15 will allow the light housing to be angled within the gap in the suspended ceiling 1, without striking the concrete ceiling.
  • the rhombus shaped side wings 15 are particularly useful for allowing the light housing 10 to be fitting within a reduced gap suspended ceiling 1.
  • lighting lamellae 30 are generally provided by curved reflective strips of material, possibly polished metal, mirrored glass or mirrored plastic.
  • Such lighting lamellae 30 are to be positioned within a louver, and are generally positioned near to the fluorescent tube in order to improve the reliability of reflecting the light into the room in the appropriate manner.
  • the lighting lamellae 30 as shown in Figure 3 and 4 is of particular use with the narrow diameter fluorescent tubes intended for use in the light housing 10 described above.
  • the lighting lamellae 30 as to be described below are, of course, not limited to being used with this light housing 10. Indeed, it is possible for the lighting lamellae 30 to be utilised within any appropriate louver or light arrangement.
  • Lighting lamellae 30 are generally known in the art, and are particularly known for use with standard fluorescent tube lighting. With the new narrow diameter fluorescent tubing, it is possible to provide much narrower light fittings 4, as the fluorescent tube is of a much smaller size. Additionally, the diameter of the narrow diameter fluorescent tubing leads to a change in the distribution of the light from the fluorescent tube, when compared with the standard fluorescent tubes common in the art. As such, in producing efficient lighting lamellae 30 for use with such narrow diameter fluorescent tubing, it is not simply appropriate to scale the known lighting lamellae to coincide with the size of the narrow diameter lighting tubes.
  • lighting lamellae 30 for the narrow diameter fluorescent tubing is advantageously reduced in its vertical dimension, so as to also improve the overall depth of the resulting light. In other words, it is advantageous to reduce the thickness of the entire light as well known in the art, and this can be achieved by means of the lighting lamellae 30.
  • FIG 3 shows three perspective views of the lighting lamellae 30 according to the present disclosure.
  • This lighting lamellae 30 is advantageously provided with three distinct regions or portions.
  • the lighting lamellae 30 is structured with a cross-section very similar to a V, each side of the V being provided by side sheets 32 of the lighting lamellae 30. These side sheets 32 meet at a bottom portion 31, which is the lowest longitudinal section providing the vertex 33 of the V-shaped lighting lamellae 30.
  • This vertex 33 extends along the length of the lighting lamellae 30, and provides a linear straight line 34 to the bottom portion 31.
  • the profile of the side sheets 32 is non-linear in both the vertical and longitudinal direction.
  • the side sheets 32 progress from the vertex 33 to the upper edges 35 forming the top points of the V cross-section, the side sheets 32 do not progress in a straight line. Rather, the side sheets 32 are somewhat curved as they move in the upward direction, assuming the bottom portion 31 to be the lowest and down-most point.
  • the side sheets 32 also curve when moving along the longitudinal direction of the lighting lamellae. This is particularly so around the upper edges 35, and indeed the higher section of the lighting lamellae.
  • the lighting lamellae 30 of the present disclosure is therefore specifically characterised by this fully three-dimensional curving of the side sheets 32, which leads to a greatly improved reflection of the light from the narrow diameter fluorescent tubes when compared with a normal lighting lamellae 30, or a normal lighting lamellae 30 which has been simply reduced in size.
  • the lighting lamellae 30 is particularly advantageous. It is possible to provide the side sheets 32 with a varying radius of curvature in the vertical direction, such that the side sheets 32 move away from each other more and more as one progresses in the vertical direction. Additionally, the longitudinal variation in the distance between the two side sheets 32 can vary in a non-linear manner. Further, this non-linear variation can also proceed by means of curves with changing radii of curvature. It is advantageous if the upper edges 35 of the lighting lamellae 30 are not formed parallel with each other, rather the gap there-between varies as one moves in the longitudinal direction.
  • a further particularly advantageous design of the lighting lamellae 30, can be determined from Figures 3 and 4 .
  • the lighting lamellae of these figures is provided with three distinct portions.
  • the lower portion 40 extends from the vertex 33 toward the upper edges 35.
  • An upper portion 42 extends from the upper edges 35 downward towards the vertex 33.
  • These two portions preferably do not meet each other toward in the middle of the lighting lamellae, rather they each join opposing sides of an intermediate portion 41 located there-between.
  • the properties of each of these portions 40, 41, 42 are distinct from each other, and lead to the overall preferable design of the lighting lamellae 30.
  • the side sheets 32 are provided with a linear structure.
  • This linear structure in particular, is manifest in the way the gap between the two side sheets 32 changes as one progresses in the vertical direction from the vertex 33.
  • the lower portion 40 has a gap between the side sheets 32 which increases in a generally linear manner, for a certain percentage of the total height of the lighting lamellae 30.
  • the lower portion 40 may extend between 40% and 60% of the vertical height of the lighting lamellae 30; more preferably it may extend for between 45% and 55% of the lighting lamellae 30; most preferably, the lower portion 40 may extend for about 50% of the vertical height of the lighting lamellae 30.
  • the lower portion 40 is also categorised in that there is no variation in the gap between the side sheets 32, when viewed in the longitudinal direction. That is, the gap between the side sheets 32 for a given vertical height remains constant across the entire length of the lighting lamellae 30, in the longitudinal direction.
  • the lower portion 40 is characterised with side sheets 32 which are in fact planar in nature, and angled such that they are not parallel with each other.
  • the upper portion 42 this is particularly categorised by a variation in the gap between the two side sheets 32 in both the vertical and longitudinal directions. That is, as one progresses through the upper portion 42 in the vertical direction, the variation in gap between the two side sheets 32 increases as one moves vertically upward in the direction from the vertex 33 to the upper edges 35.
  • the gap between the two side sheets 32 also varies in this direction. This is somewhat different from the variation seen in the lower portion 40, wherein the gap stays constant as one moves in the longitudinal direction.
  • the upper portion 42 preferably extends from a point which lies between 60% and 80% of the total height of the lighting lamellae 30, obviously taken in the vertical direction. More preferably, the upper portion 42 extends from a point which is between 65% and 75% of the total height of the lighting lamellae 30, and most preferably the upper portion 42 lies at a point 70% up the vertical height of the lighting lamellae 30.
  • the intermediate portion 41 is specifically defined as lying between the two above defined portions, those of the lower 40 and upper 42 portions. The intermediate portion 41 is defined as having a non-linear change in the width of the gap between the two sheets 32 in the vertical direction, but still has a constant gap between these two sheets 32 when progressing in the longitudinal direction and maintaining a fixed height along the lighting lamellae 30.
  • the gap between the two side sheets 32 does not change along the longitudinal direction.
  • the variation in gap between the two side sheets 32 changes in a non-linear manner.
  • this non-linear manner is characterised by a curve with a changing radius of curvature.
  • Table 1 shows data points characterising the width of the gap between the two side sheets 32 of the lighting lamellae 30.
  • This table expressly links to the data shown in Figure 4 , and shows the gap between the two side sheets 32 at a series of points in the X direction, starting at 0 and running to 26, and also in the Y direction again starting at 0 and running to 18.
  • the value of the gap between the two side sheets 32 is given in millimetres. For example, at a point X 12 and Y 12, the gap between the two side sheets is 2.09 mm.
  • This table clearly shows the variation being described above with regard to the lower 40, intermediate 41 and upper 42 portions.
  • the data shown in table 1 is purely for example, and is included merely to show a possible variation of the gap between the two side sheets 32 in the lighting lamellae 30.
  • the lighting lamellae 30 can have a different overall height and length, and further it may have a different ratio of lower 40 intermediate 41 and upper 42 portions.
  • the size of the gap shown in table 1 is also for example only, and indeed the gap could be greater or smaller depending upon the requirements of the design.
  • the X 0 point is taken at the centre 37 along the longitudinal direction of the lighting lamellae 30.
  • the lighting lamellae 30 is preferably symmetric around this point, and thus the same structure would be observed for the second half of the lighting lamellae 30 extending from the centre point 37 to the left, as viewed in Figure 4 .
  • top surface 38 with a recess or trough design, such that the cross-section of the lighting lamellae 30 is that of an arrowhead. Once again, this will lead to light striking the top surface 38 being reflected at an angle with respect to this incoming light, wherein the angle is not 0°, again leading to improved reflection of the light around the room.
  • the height of the lighting lamellae 30 varies in the longitudinal direction. That is, the height of the lighting lamella 30 is preferably greatest at the two outer sides 36, and this reduces steadily towards the centre 37.
  • a linear change is shown in the figures between the outer sides 36 and the centre 37. This is by way of example only, and indeed the height of the lighting lamella 30 could vary in a curved manner, either concave or convex curved.
  • the provision of this dip in the height of the lighting lamellae 30 towards the centre 37 is advantageous as it allows for the fluorescent tube to be located within this dip and at the centre 37.
  • Providing the lighting lamellae 30 with a surface which goes above the lower point of the fluorescent tube not only improves the light distribution around a room, but allows for a reduced height lighting lamellae 30.
  • both the light housing 10 and lighting lamellae 30, can clearly be combined to generate an appropriately narrow light housing 10.
  • the aspects described with respect to each of the light housing 10 and lighting lamellae 30 are not intended to be specifically limiting. Any implied combination of features for each of these structures is not intended to be a specific limiting combination, and indeed all aspects of each of the light housing 10 and lighting lamellae 30 are to be considered as interchangeable and optional depending upon the desired results.
  • both the light housing 10 and lighting lamellae 30 are advantageously structured and designed to lead to narrower light fittings, and are particularly useful with the narrow diameter fluorescent tubes.
