Definitions

  • This invention relates to a light fitting more particularly but not exclusively to a down-light fitting.
  • a light fitting comprising a tubular body having a cylindrical inner wall, preferably a right circular cylindrical inner wall, with an inner surface having at least one resilient light engaging formation, and a peripheral flexible flange at each end configured to be fitted into a complimentary aperture in a ceiling.
  • the invention further provides for the resilient light engaging formation to be formed into at least one ring, preferably as a series of contiguous rings, further preferably a series of rings each comprising a plurality of equidistantly spaced apart tabs extending radially inward from the inner surface of the inner wall.
  • the invention also provides for the moulded material to be one providing heat resistance and photo luminescence, for the tubular body to be reversible and for the series of rings to be slotted.
  • the body may be made in various colours and can be provided in a range of sizes to accommodate globes of different dimensions.
  • At least one flange to include a semi-circular radial rib.
  • one of the peripheral flexible flanges to have a circular shape and for the other flange to have a square shape, or any other shape.
  • the sides of the square flange to be curved inwardly, preferably to a small degree, most preferably such a small degree that it is imperceptible by the human eye when in use.
  • the light fitting to be reversible, which preferably angles the flange to be directed away from the opposing flange, and further preferably for the edges of the square flange to fold in towards the axis of the tubular body.
  • the interface between the tubular body and the flanges to be notched operatively to at least partly prevent damage to the fitting when the fitting is fitted to a ceiling or reverse inside out.
  • tubular body to have a height ranging from 12mm to about 33mm, and preferably to have a height of about 22mm, and for the distance between the two flanges to be between about 6mm to about 20mm, and preferably to be about 7.5mm to operatively allow the fitting to function with ceiling boards having thicknesses in the range of about 6mm to 25mm, preferably between about 8mm to 12mm.
  • a method of converting a ceiling down-light into a three dimensional light feature by reversing a light fitting as defined above and locating the side with the square flange to be visible, at which stage the other side becomes the part that keeps the fitting inside the ceiling.
  • a further feature of the invention is that it disburses light through its body and flanges in multiple directions in accordance with the different designs and textures that can be accommodated on its outer surfaces, and this has the added benefit of increasing the beam angle of an LED light which is usually restricted to narrow beam angles.

  • FIG. 1 A first embodiment of a down-light light fitting (1 ) according to the invention is shown in Figures 1 to 8.
  • the fitting (1 ) includes a tubular body (2) with a peripheral flange (3, 4) at each end.
  • the flanges (3, 4) extend over the tubular body to define a gap (5) between them.
  • each ring (6) is provided with a four slots (7), which align with the slots (7) in the remainder of the rings (6) to form four equidistantly spaced apart longitudinal passages (8) through the rings (6).
  • the tubular body also includes on its outer surface a plurality of spaced apart protrusions (9).
  • the light fitting is manufactured from a resiliency flexible plastics material providing rubberlike characteristics. Silicon rubber of suitable hardness is the material of preferred choice.
  • the rubber-like material is impregnated or coated with photo luminescent material, at least in respect of the flanges.
  • the flanges (3, 4) project radially at right angles with respect to the longitudinal axis of the body (2).
  • the two flanges (3, 4) define between their inner surfaces (10, 1 1 ) the gap (5) which fits over the edge of a circular aperture (12) in a ceiling (13).
  • the fitting (1 ) is positioned through a normal size aperture (12) in a ceiling board (8) used for fitting a down-light. This is achieved through the flexibility of the flanges (4) and (5).
  • the protrusions (9) on the outer surface of the tubular body (2) assist in gripping the ceiling (13).
  • the internal dimensions and spacing of the rings (6) enable an LED light (14) to be located positioned in various configurations within the fitting.
  • the depth of the light (14) into the fitting and angle of the light (14) within the fitting may be changed at will. This allows a light to be directed to almost any position in the room underneath the ceiling.
  • the depth adjustability also allows the size of the spot that the light presents to be adjusted easily. If the light (14) is located deeper into the fitting (1 ), the size of the spot decreases. If it is located shallower within the fitting (1 ), then the size of the spot increases to what would be the designed maximum spot size as determined by the lighting angle of the light (14).
  • the light (14) is resiliency held flush with the fitting (1 ).
  • the flange (3) on one end of the body (2) is circular in shape and the flange (4) on the opposite end is square in shape.
  • a particular feature of the down-light fitting (1 ) is that is can be reversed inside out, as shown in Figures 7 and 8.
  • the circular flange (3) remains circular when turned inside out, with the only noticeable difference being that the outer surface of the flange is smoothly rounded instead of slightly angled.
  • a very striking visual feature results from the reversing inside-out of the body (2).
  • the flange (4) then becomes angled away from the opposing circular flange (3).
  • the corners (15) of the square flange (4) point outward but the edges (16) fold inward towards the axis of the tubular body (2). This creates a visual appearance resembling a flower (17), as shown in Figures 7 and 8.
  • the flange (4) lights up when a light is turned on. This creates a striking visual effect on the ceiling where the down-light if fitted.
  • the down-light is transformed into a three-dimensional light, in this instance, in the form of flower (17) by reversal of the fitting, or used conventionally refracts light through its sides creating more light than a conventional non transparent light fitting.
  • a second embodiment is shown in Figures 9 to 12.
  • a light fitting (20) that includes a tubular body (21 ) with a peripheral flange (22, 23) at each end.
  • the flanges (22, 23) extend over the tubular body to define a gap (24) between them.
  • the body (21 ) of this embodiment also includes a set of spaced apart circumferential contiguous rings (25).
  • Each ring (25) is provided with a four slots (26), which align with the slots (26) in the remainder of the rings (25) to form four equidistantly spaced apart longitudinal passages (27) through the rings (25).
  • the body (21 ) also includes on its outer surface a plurality of spaced apart protrusions (28).
  • the two flanges (22, 23) in this embodiment (20) are both circular, as shown in Figures 9 to 12.
  • the same lighting effect that is possible with the first embodiment (1 ) by adjusting the depth and angle of the light fitting (29) may also be achieved with this light fitting (20).
  • a third embodiment of a light fitting (40) according to the invention is shown in Figures 13 to 15.
  • the set of spaced apart circumferential contiguous rings (6, 25) that were present in the first (1 ) and second (20) embodiments is replaced by a plurality of spaced apart rings (41 ), each ring formed by eight equidistantly spaced apart tabs (42) that extend axially from the inner surface (43) of the cylindrical body (44).
  • the set of rings (41 ) formed by the tabs (42) grip the outer surface of the body of an LED light to hold it securely in position.
  • the spacing (45) between the tabs (42) provide pathways for the movement that air which operatively aids in the removal of heat from a light fitted in the fitting (40).
  • the light fittings (1 , 20, 40) are manufactured from resiliency flexible plastics material providing rubber-like characteristics. Silicon rubber of suitable hardness is the material of preferred choice.
  • the rubber-like material is impregnated or coated with photo luminescent material, at least in respect of the flanges.
  • the down-light fittings (1 , 20, 40) may be used in a number of applications, which extend beyond the conventional down-light use, and it has a plurality of advantages over conventional down-light fittings. These include:
  • It may be used as an aircraft landing light feature, in which the fittings provide visible light when all lights are switched off intentionally; 3) It may be used as an aircraft emergency light feature, in which the fittings provide visible light when all lights are cut off as result of an emergency;
  • the photo luminescence allows the light fitting to act as a power failure light back up, or an electricity load shedding light back up;
  • the fitting can be used as a comfort light for children (zero electricity required);
  • the fitting allows for electricity savings by absorbing light and emitting it later again in the form of a night light, or garden feature soft light, camping, car or boat accessory
  • the down-light fitting accommodates all down-light sizes, diameter and height;
  • the fitting provides uniquely positioned dust and ventilation slots which also serve as globe dislodgement spaces for ease of globe removal;
  • the fitting When a light housed by the fitting is switched on, the fitting is semi-transparent or translucent and gives off more light rather than just through its aperture; 25) The fitting is softer in nature compared to conventional down-light fittings, which means the damage to the roof during installation or removal is less as opposed to its steel counterparts and therefore easier to work with; and
  • the fitting is made from material that is non-corrosive. It can therefore be washed to clean it from dust accumulation with normal tap water and if desired a cleansing solution.
  • the light fittings (1 , 20, 40) provide for a down-light to be located within in it.
  • the length of the tubular body may vary from 12mm to about 33mm, and the distance between the two flanges ranges between about 6mm to about 20mm.
  • This means that the light fittings (1 , 20, 40) may be used with ceiling boards having thickness in the range of about 6mm to about 20mm.
  • the preferable height of the tubular body is about 22mm and the distance between the two flanges ranges is about 7.5mm.
  • the preferable ceiling board thickness ranges between about 8mm to 12mm.
