专利说明:
[0001] The present invention is in the field of light fittings, in particular in providing a housing for a light emitting source. In particular embodiments, the housing may be a housing for use in a downlight, for example situated in the ceiling of a room of a building. Background
[0002] Different light fittings and housings have been designed and employed for a number of uses. For example, many bulbs are suspended by a cable from a ceiling, and are then surrounded by a thin piece of material, forming a lampshade. Other light emitting means may include lamps, torches and street lights.
[0003] Downlights are employed in a number of locations, for example downlights are employed in the ceilings of buildings, as well as on walls, under cupboards, and on worktops or other raised surfaces. In some cases such lights may be situated on the floor and may be used as uplights, for example to provide emergency lighting or to provide lighting of a particular item or feature.
[0004] Previous downlight housings have been comprised of a body that the light emitting source is held within, and a separate element, that is used for connecting the downlight housing and the ceiling (or other mount surface) together during installation. Such an element may be referred to as an arm or clip. Statement of Invention
[0005] Embodiments of the claimed invention are directed to a housing for a light emitting source comprising a body formed of one or more walls, wherein the one or more walls surround a volume, and wherein the body has a proximal end and a distal end, wherein the distal end is open, and at least one arm attached to the body, wherein the arm is configured to secure the housing to a surface, wherein the body and the at least one arm are formed of unitary construction. The unitary construction of the body and the arm is advantageous because this means that during installation the relative position of the arm and the body is set, and so this reduces the complexity of the installation process, especially when installing the housing in a hard to access area.
[0006] This removes the need to hold the arm and the housing in a fixed position relative to one another during the installation process, hence simplifying the installation process, especially if the light is being installed in a hard to access position.
[0007] Optionally, the housing further comprises a bezel at the distal end of the body. The bezel may provide a further decorative element and enable accurate positioning of the housing during installation. In a particular embodiment, the bezel is also formed of unitary construction with the unitary body and at least one arm. That is, all three parts are formed together, for example in a moulding process, rather than the bezel being formed separately and later coupled to the body and arm.
[0008] Optionally, the housing is for a downlight to be installed a surface of a building, such as a ceiling or a wall. This allows the downlight to light a room, or portion of a room, without suspending the light from the ceiling by a cable.
[0009] Optionally, an inner surface of the one or more walls of the body is reflective to light, preferably the whole inner surface of the walls is reflective. This makes the housing efficient as it reflects rather than absorbs a high percentage of the light emitted by the light emitting source. It will be appreciated that any reference to the "body" in the present application may be replaced with the term "reflector" in embodiments in which the surface of the body is reflective.
[0010] Optionally, the bezel is shaped to flare outwardly from the body to form a rim. Optionally, the bezel is configured, when the housing is installed, to extend parallel to the surface in which the housing is installed. This may be have the effect of the housing blending in with the surface on which it is attached so that the housing is pleasing to the eye of the user.
[0011] Optionally, the housing further comprises a heat sink attached to the body. This may allow the housing to remain at a substantially constant temperature during use, reducing potential fire risks, unwanted expansion of the housing due to heating, and potential damage to the surface in which the housing is installed.
[0012] Optionally, the heat sink is attached to the proximal end of the body. This may allow the heat sink to be hidden from view when the housing is installed.
[0013] Optionally, the heat sink is attached to the body by a snap-fit. This can make the heat sink easy to install.
[0014] Optionally, the heat sink is detachable from the body. Therefore in some applications where a heat ink is not desirable the housing may deployed alone. Moreover the housing and the heat sink may be sold separately and assembled on site to reduce transportation costs.
[0015] Optionally, the heat sink is formed of aluminium. Aluminium will absorb a large amount of heat, and is a good conductor. Aluminium is also relatively low cost relative to other suitable materials such as copper.
[0016] Optionally, the housing is formed by a die casting process. This may make the housing cheaper to manufacture.
[0017] Optionally, the housing further comprises means for transmitting electrical power to a light emitting source. This enables a light emitting source to be powered via the connection in the housing. Optionally, the housing further comprises a light emitting source, for example an LED. The light emitting source may be electrically connected to the means for receiving electrical power.
[0018] Optionally, the light emitting source is positioned within the volume surrounded by the one or more walls of the body. This may enable a large proportion of the light generated by the light emitting source to light a room, or portion of a room.
[0019] Optionally, at least a portion of the body is concave. This may allow the light to spread unobstructed from the housing into a room.
[0020] Optionally, at least a portion of the body is convex. This may allow optical properties of the light to be adjusted, so the light may be further diffused, or focused on a particular location.
[0021] Optionally, the housing is formed by injection moulding. This may lower the cost of production of the housing.
[0022] Optionally, the one or more arms comprises a ceiling spring. This may reduce the risk of the housing becoming disassociated from the surface in which it is installed.
[0023] Optionally, the housing comprises two arms. This may provide enough points of contact for the housing to remain secure, but may also limit the amount of material needed to construct the housing, and so reduce costs of production.
[0024] Optionally, the arms are positioned 180 degrees apart from each other around the housing. This may allow the weight of the housing to be evenly distributed by the two arms.
[0025] Optionally, the arm is attached to the body at the proximal end of the body. This may allow the arms to be out of sight when the housing is installed.
[0026] Optionally, the proximal end of the body is at least partially closed, for example it may have an opening sufficient to permit a light source to establish electrical connections. However, having a covered opening at the proximal end can allow an even greater proportion of the light to be emitted out of the distal end of the housing, and so make the housing more efficient.
[0027] Optionally, the axial cross section of the body is circular or curved. This may allow the light to be distributed evenly as it exits the distal opening.
[0028] Optionally, the axial cross section of the body may be triangular. Optionally, the axial cross section of the body may be in the shape of a polygon, for example a square. This may allow the distribution of the light to be controlled by the shape of the axial cross section. The shape may also be aesthetically pleasing.
[0029] Optionally, the radius of the distal end of the body is greater than the radius of the proximal end of the body. This may allow a great proportion of the light generated by the light emitting source to pass through the distal end of the housing.
[0030] Optionally, the housing is formed from plastic. This may reduce the cost of manufacture.
[0031] According to a further aspect there is provided a method of manufacturing the housing comprising forming a body comprising one or more walls, wherein the one or more walls surround a volume, and wherein the body has a proximal end and a distal end, wherein the distal end is open and forming at least one arm attached to the body, wherein the arm is configured to secure the housing to a surface, wherein the body and the arm are formed of unitary construction.
[0032] Optionally, wherein the method of manufacture comprises injection moulding. According to a further aspect there is provided a method of installing the housing, wherein the method comprises positioning the housing and the arm through an opening in a surface, and securing the arm to the surface, such that the housing is secured to the surface. This may increase the ease with which the housing may be installed. Brief Description of Figures

Figure 13 shows an exploded view of the elements attached to the housing to form a light fitting according to one embodiment. Description of Figures
[0034] Figure 1 shows a housing according to one embodiment. The housing in Figure 1 comprises a body 1 formed of one wall, such that the body encircles or surrounds a volume. The body has a proximal end at the top of the Figure, and a distal end, at the bottom of the Figure. Two arms 3 are attached to the body, and each is configured to secure the housing to a surface. The body 1 and the arms 3 are formed of unitary construction. The housing shown in Figure 1 may be installed in the ceiling, wall or floor of a building, or in any other suitable location.
[0035] Figure 1 shows a bezel 5 attached to the body at the distal end of the body. The bezel 5 flares outwardly from the body to form a rim (this can best be seen in Figures 5 and 6). The bezel 5 shown in Figure 1 appears as a thin line, since the bezel 5 extends at 90 degrees to the vertical axis (the axis between the proximal and distal ends of the body 1, running through the centreline of the body 1). This allows the bezel 5, when the housing is installed, to run parallel to the surface in which the housing is installed.
[0036] The body 1 is shown as being formed of one wall that is continuous and curved around to encircle the volume. The body 1 is also shown as being concave, such that the width of the body at the proximal end is less than the width of the body at the distal end.
[0037] The arms 3 are attached to the body 1 at the proximal end of the body 1. The arms 3 extend radially out away from the body 1, and down toward the distal end of the body 1. The arms 3 may be resiliently deformed in installation so that they can pass through an aperture through which the housing is being installed and rests on the inside surface of the aperture to prevent easy removal of the housing after installation. The clips therefore act to secure the housing within an aperture of the surface. The arms 3 act as ceiling springs.
[0038] Figure 1 shows two such arms 3, these arms 3 are positioned 180 degrees apart from each other, such that they extend on the same axis directly opposite one another. When installed this allows the arms 3 to bear an equal load of the weight of the housing, and so there is no imbalance that may lead to the housing becoming insecure. It is noted that in other embodiments other numbers of arms 3 may be used, for example three, four, five or six arms may be used. In some embodiments only one arm 3 may be used, this may not be as secure as using multiple arms 3, however this may reduce the cost of manufacture and whilst still being secure enough for many applications. It is noted that although in some embodiments arms may be located equidistant to each other, they may in other embodiments be positioned irregularly around the body. For example, arms 3 may be positioned so as not to interfere with other elements of the housing or lighting fixture or other components that are installed in the building surface.
[0039] The proximal end of the body is shown in Figure 1. This comprises a means for attaching the housing to a further object, for example a heat sink (see Figures 7-13). The attachment means 7 may be any suitable form of attachment means, for example screw thread, bayonet fitting, or snap fit (as is shown in Figure 1). The snap fit element allows the housing to quickly and easily be married to another element, increasing ease of installation.
[0040] It is noted that the entire housing of Figure 1 is formed of unitary construction. Therefore both the arms 3 and body 1 are formed of unitary construction. In the embodiment shown the bezel 5 is also formed of unitary construction with the arms 3 and the body 1. Moreover in the embodiment shown the attachment means 7 is also formed of unitary construction with the rest of the housing. It is also noted that the housing of Figure 1 may be formed of plastic, for example by injection moulding.
[0041] Figure 2 shows a view of the housing of Figure 1 from beneath the distal end of the housing. As shown in Figure 2 the axial cross section of the housing is circular. Other cross sectional shapes are envisaged for other embodiments, such as triangular, square, and other polygons. A specific shape may be used for a specific location where it is required to achieve effective installation, or due to design considerations. A circular axial cross section may be preferable so that light is emitted out of the distal end of the housing in a homogeneous and isotropic manner, such that the environment in which the housing is situated is evenly lit.
[0042] Figure 2 shows the body 21 of the housing (specifically the inner wall of the body), and the bezel 25, as well as an opening 29 suitable for holding a light emitting source, and the most radially extending portion of the arms 23 shown in Figure 1. A light emitting source may be any suitable light emitting source such as an LED, a halogen bulb, a wire filament bulb, or any other light source. The opening 29 is situated at the proximal end of the body. The proximal opening 29 has a smaller radius than the distal opening of the body. A light emitting source positioned within the opening 29 may be within the volume encircled by the wall of the body. The housing may comprise means for receiving electrical power (not illustrated), and the light emitting source may be electrically connected to the means for receiving electrical power. It is noted that in other embodiments the proximal end of the housing may be closed.
[0043] Figure 2 shows the arms 23 extending radially further than the bezel 25 of the housing. The bezel 25 is also shown to be formed of two portions, a flared portion extending both radially out, and distally from the body, and the rim. Both these elements are also shown in Figure 1.
[0044] Figure 2 also shows that distal end of the body is open. This allows the light to escape from the housing, to light the environment around it. To aid in increasing the proportion of light that is emitted from the distal end, the inner wall of the body 21 of the housing may be reflective to light. This may be a thin metal covering, or any other suitably reflective covering and may be formed for example by vacuum deposition of the metal onto the housing surface.
[0045] Figure 3 shows a side view of the housing of Figures 1 and 2 perpendicular to the plane on which the arms are situated. Similarly to Figure 1, the bezel 35 is shown, as well as the body 31 and the attachment means 37. Only one arm 35 is shown in figure 3. This is because the other arm 35 is obscured by the body 31 of the housing. The features of Figures 1 and 3 are otherwise the same.
[0046] Figure 4 shows a view from above the proximal end of the housing of Figures 1, 2 and 3. This shows the proximal opening 49, the attachment means 47, the arms 43, the outer wall of the body 41 and the bezel 45. The most radially extending portions of the arms 43 extend further radially out than the bezel 45 from the centre of the housing. The attachment means 47 comprises a snap fit mechanism, although other mechanisms for joining the housing to a secondary element may be employed instead of the snap fit mechanism.
[0047] Figure 5 shows a perspective view from above the housing of Figures 1-4. This shows the proximal opening 59, the attachment mechanism 57, the arms 53, the body 51, and the bezel 55.
[0048] Figure 6 shows a perspective view from below of the housing of Figures 1-5. This shows the distal opening 69, the attachment mechanism 67, the arms, the body 61, and the bezel 65.
[0049] Figure 7 shows a side view of a housing parallel to the axis on which the arms are situated according to one embodiment of the invention. The housing of Figure 7 is attached to a heat sink 70. The housing is substantially the same as the housing shown in Figures 1-6.
[0050] The heat sink 70 in Figure 7 is shown attached to the housing, this attachment is performed by the attachment means 77. The attachment in this embodiment is therefore at the proximal end of the housing. In other embodiments the heat sink 70 may be attached to the housing at a different point on the housing, for example on the outer wall of the body. The heat sink extends around the body of the housing. The heat sink 70 is formed of an element comprising multiple radial panels 72 separated by gaps. The gaps in the radial side panels 72 may allow air to circulate throughout the housing and heat sink, so that air conducts heat away from the housing and heat sink. This may ensure that the housing and heat sink do not exceed a desired temperature in normal use.
[0051] Figure 8 shows a view of the housing of Figure 7 from beneath the distal end of the housing. The radial side panels of the heat sink do not extend radially out as far as the bezel 85, and so the heat sink is not visible from the viewpoint of Figure 8. Therefore Figure 8 is substantially similar to Figure 2.
[0052] Figure 9 shows a side view of the housing of Figures 7 and 8 perpendicular to the axis on which the arms 93 are situated. This shows that at the position where the arms 93 extend form the body the heat sink 90 is adapted to allow said arms 93 therethrough. The heat sink 90 therefore has a gap between the radial side panels 92 that is larger at the point where the arms 93 extend from the body. This allows the arm 93 to be situated within the gap between the radial side panels 92. Moreover, at the proximal end of the radial side panels 92, near the point the arms 93 extend from the body, the radial side panels 92 have a further cut out portion so as to not interfere with the arm 93. In other embodiments the gap between the side panels 92 may be increased so that such a cutout of the radial side panel 92 is not required. The heat sink 90 may be detachable from the body.
[0053] The heat sink may 90 be manufactured out of any suitable material. A suitable material may have a high thermal conductivity, and a high specific heat capacity. Such a material includes most metals for example aluminium or copper. Of these materials Aluminium may be preferable because it is more cost effective.
[0054] Figure 10 shows a view from above the proximal end of the housing of Figures 7, 8 and 9. This shows the structure of the heat sink 100, as well as arms 103 and the bezel 105 of the housing. The heat sink includes elements that allow air to circulate around the housing and heat sink to transfer heat away from the housing. Beneath the sub-branches 104 the heat sink can be seen in a snap fit arrangement with the attachment means of the housing 107.
[0055] Figure 11 shows a perspective view from above the housing of Figures 7-10. This shows the proximal end of the heat sink 110, as well as one arm 113 of the housing, and the bezel 105 of the housing. The arm 113 extends through a gap in the radial side walls 112 of the heat sink. The heat sink is constructed as described above in relation to Figure 10. The heat sink 110 does not extend radially as far out as the bezel 115 from the centre of the housing.
[0056] Figure 12 shows a perspective view from below of the housing of Figures 7-11. This shows the distal opening of the housing 128, as well as the bezel 125 of housing, the body 121 of the housing, and the radial side panels 122 of the heat sink 120. The arm 123 extends through a gap between two radial side walls 122. Other gaps between radial side walls 122 are shown approximately 45 degrees apart.
[0057] Figure 13 shows an exploded view of the elements attached to the housing to form a downlight according to one embodiment.
[0058] A light emitting source 141 is shown in Figure 13. This may be positioned within the proximal opening (not shown in figure 13), or it may be attached to the inner wall of the body 131 within the volume enclosed by the body 131. In the embodiment shown it is positioned in the proximal opening. Above the light emitting source 141 electronics 142 are shown. This may include circuitry to allow the light to be operable remotely. For example, the light emitting source 141 may be an "internet of things" device, and so connected to external devices via a connection such as GSM, 3G, 4G, 5G, Bluetooth or any other such communication means. Alternatively, the light emitting source 141 may be programmed internally such that circuitry comprises a processor and a memory, and the memory stores instructions to come on at a certain time of day, or at a certain brightness, or if movement is detected. Above the circuitry is a cell that may be used to power the light emitting source. In other embodiments the light may be powered by mains electricity, and the housing may be connected to receive electrical power.
[0059] Above the cell 142 is the heat sink 130. The heat sink 130 has the structure described above with the radial side walls 132 separated by gaps.
[0060] The components shown in Figure 13 may be fitted together to form a functioning light, and specifically a functioning downlight. The light may be connected with the circuitry 142 and the cell 143, and positioned within the proximal opening of the body 131. The heat sink 130 may be attached the body via the snap fit attachment means 137, and then the downlight may be installed onto a surface to illuminate an area.
[0061] The housing shown in any of the above Figures may be manufactured using the method described herein. The method may comprise forming a body formed of one or more walls, wherein the one or more walls encircle a volume, and wherein the body has a proximal end and a distal end, and wherein the distal end is open. The method may also comprise forming at least one arm attached to the body, wherein the arm is configured to secure the housing to a surface and wherein the body and the arm are formed of unitary construction. The manufacturing may be performed using injection moulding in order to create the housing out of plastic. An optional step may comprise attaching a layer of reflective material to the inner wall of the housing, for example in a vacuum deposition step.
[0062] The housing shown in any of the above Figures may be installed by inserting the housing through an opening in a surface, and securing the arm to the inner wall of the surface, such that the housing is secured within the opening. Inserting the housing through the opening in the surface causes temporary deformation of the arm or arms of the housing. Once through the opening, the arms spring back to rest on the inner wall of the surface and secure the housing within the opening. The rim and the arms may be used to sandwich a surface such that the rim of the bezel applies a force to the other, outer side of the surface in order to keep the housing secured in position.
[0063] It will be appreciated from the discussion above that the embodiments shown in the Figures are merely exemplary, and include features which may be generalised, removed or replaced as described herein and as set out in the claims. With reference to the drawings in general, it will be appreciated that the functionality need not be divided in the manner shown, and should not be taken to imply any particular structure other than that described and claimed below. The function of one or more of the elements shown in the drawings may be further subdivided, and/or distributed throughout apparatus of the disclosure. In some embodiments the function of one or more elements shown in the drawings may be integrated into a single functional unit.
