Abstract:
Functional yet decorative luminaires intended to create distinctive environments within specific areas of a space in which one or more luminaires are used, the luminaires of the invention visually tie to architectural elements of the space by providing a customizable glow of color surrounding a typically white light that acts to illuminate the space functionally. A downlighting luminaire configured according to the invention as one example is typically configured to utilize two separate reflectors, usually reflectors having concave reflective surfaces and being mounted concentrically within a housing, an inner reflector directing light centrally through an aperture of the luminaire with the light so directed typically being white light useful for illumination intended to facilitate usual activities within the space. An outer reflector is spaced from the inner reflector with a transparent or translucent disc, such as an acrylic plastic disc, being held between the reflectors, the disc having a colored film adhered preferably to lower surfaces thereof to cause portions of the light emanating from lamping disposed above the disc to be colored by passage through the colored film, the disc being readily removable and replaced with a disc having a different color adhered thereto so that a particular luminaire can be customized as to color selection depending on user choice at any given time. An annulus of glowing, colored light exits the periphery of the luminaire aperture outwardly of the inner cone, the reflective surfaces of the outer reflector directing at least portions of the colored light passing through the disc and colored film through an annular aperture of the luminaire, thereby creating a distinctive appearance of a central, white shaft of light emanating from the inner reflector and a glowing annulus of colored light surrounding the white shaft of light. Peripheral edges of the inner reflector can be positioned flushly with the luminaire aperture or can extend to one or more positions outwardly of the luminaire aperture and thus “proud” of a ceiling or the like within which the luminaire is recessed, surface-mounted or pendently mounted inter alia.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates generally to luminaires such as downlighting and/or pendently-mounted luminaires and particularly to such luminaires having multiple reflectors arranged such that light reflected through a luminaire aperture by at least one of the reflectors is colored to produce a dramatic appearance. 
     2. Description of the Prior Art 
     The use of downlighting has expanded in recent years due in part to a flexibility of use of the wide variety of available downlighting luminaires as well as the ability to apply downlighting in a variety of environments requiring either general lighting, task lighting, accent lighting and the like including combinations thereof. The very nature of downlighting permits the luminaires employed to be relatively unobtrusive since downlighting luminaires are typically recessed in a ceiling or the like. However, downlighting luminaires can provide a decorative function in addition to particular lighting functions by virtue of a multitude of options involving design features of the luminaires themselves as well as characteristics of the illumination produced by downlighting luminaires of particular configurations. Downlighting luminaires of the variety characterized at least in part by decorative illuminated produced within an environmental space are known and often involve color imparted to illumination produced by lamping that generates white light but which is colored prior to exiting luminaire apertures by means of colored lenses, diffusers and the like. Such decorative downlighting luminaires are available in the marketplace and have typically been utilized to draw attention to specific areas within an environmental space or to create an environment of distinction within a space as well as to provide a visual tie to architectural elements. In such applications, decorative downlighting luminaires have previously been used to highlight specific areas within an environmental space such as a receptionist or guest services desk, the illumination produced by such decorative downlighting luminaires permitting a viewer to more easily determine a location within a relatively larger space where instructions such as directions and the like can be obtained as well as being able to recognize a feature display area such as in a retail environment, or a snack bar or the like in a lobby or bookstore, as examples. Decorative downlighting luminaires producing distinctive illumination such as colored illumination can advantageously be used to tie or complement a color pallet employed by an architect or interior designer and to create distinctive environments such as in upscale offices, gathering places, corporate lobbies and the like. Such decorative downlighting luminaires must necessarily provide distinctive capabilities when compared with standard downlighting luminaires since decorative downlighting capabilities are typically employed in environments wherein other downlighting luminaires are employed for general lighting, task lighting and the like. Decorative downlighting luminaires must also be functional and efficient and thus be capable of those usual characteristics associated with downlighting luminaires, for example, efficiency, ability to dim, production of usable light, advantageous spacing, etc. Decorative downlighting luminaires must also be easy to assembly, install and wire without the need for uncommon tools and designed such that handling of such luminaries during installation does not result in cuts, abrasions or other injury to installers. Still further, decorative downlighting luminaires must also be easily maintained by relatively inexperienced personnel such that relamping and repair is readily accomplished without the need for particular training. In maintenance situations, maintainable components such as lamping must be readily accessible. 
     Particular decorative downlighting luminaires presently available are configured to produce a decorative function by means of trim employed essentially at the luminaire aperture, such trim typically taking the form of glass or acrylic rings or plates of varying sizes and configurations, such rings and plates usually having integral color and being disposed in the luminaire aperture or suspended below the aperture. Certain available decorative downlighting luminaires include medallions or decorative shapes, typically transparent cones or spheres, suspended at the center of a glass or acrylic ring. Certain other prior decorative downlighting luminaires include non-glass decorative elements such as acrylic elements including metallized finishes such as brushed or natural aluminum, brass, stainless steel or perforated metal as examples. Lamping for prior decorative downlighting luminaires ranges broadly in kind from incandescent, fluorescent, HID, and the like. 
     The variety of decorative downlighting luminaires available in the marketplace has not fully addressed user needs especially as to desired abilities to draw attention to specific areas within a space in a dramatic manner and for tying of illumination to architectural elements of a space. While such prior decorative downlighting luminaires have employed rings of colored glass or acrylic materials as annuli about peripheries of circular luminaire apertures either within the luminaire apertures or suspended therebelow, the illumination produced by such luminaires have appearances such as are associated with light passing through a lens or diffuser. Such illumination so produced lacks a dramatic glow such as would be desired by a user within certain use environments including environments intended to be distinctive. 
     Similar comments can be made relative to luminaires of other description including pendently mounted luminaires whether mountable directly to a ceiling or by mounting from a track or the like. Such luminaires can also be configured according to the teachings of the invention to yield the dramatic appearance disclosed herein. 
     The decorative luminaires of the present invention address needs thus alluded to by providing distinctive illumination characterized by an interior shaft of light directed into a space, such shaft of light typically being white light intended to provide certain typical lighting functions, the shaft of light further being essentially surrounded by an annulus of colored light presenting an exceptionally pleasing “glow” without having the appearance of being filtered through a lens or diffuser such as is commonly disposed within a luminaire aperture. The illumination produced by the present luminaires can be readily customized to provide differing coloration of illumination with minimal modification of present decorative luminaires. The decorative luminaires of the invention provide in this respect and in other respects to be described hereinafter advances in the art not heretofore contemplated. 
     SUMMARY OF THE INVENTION 
     The invention provides in several embodiments decorative luminaires characterized in part by concentric reflectors and one or more sources of light, an inner reflector typically having a light source positioned in surmounting relation to an inner end thereof and through which inner reflector a portion of the light generated by the light source passes either directly or through reflection from reflective surfaces of said inner reflector outwardly of the luminaire into an environmental space that is to be illuminated. In preferred embodiments of the invention, that light source producing illumination passing through the inner reflector produces white light as is useful for general illumination and the like, light thus passing through the inner reflector being directed into an environmental space for the typical uses associated with downlighting and other illumination applications. An outer reflector preferably concentric with the inner reflector is spaced therefrom and is typically mounted within a downlighting luminaire housing, as an example, a planar annulus typically formed of glass or acrylic material being disposed between the inner and outer reflectors at a location spaced from an aperture of the luminaire and preferably near an anterior end of the inner reflector, the annulus being mounted by clips carried by the luminaire housing. The annulus is either integrally colored, coated with a transparent or translucent colored film or covered with a colored film placed on top surfaces of the annulus or adhered to surfaces thereof, preferably lower surfaces of said annulus. When integrally or permanently colored with a particular coloration, the annulus can be removed to customize the luminaire as by substitution of an annulus of one color with an annulus of a differing color as desired. Use of an adherent film, as another example, permits utilization of a single annulus, preferably a clear, colorless annulus with films of differing coloration being employed to impart color to light produced by either the same light source that produces light passing through the inner reflector or a separate light source positioned to pass light only through the outer reflector, light passing through the outer reflector and out of the luminaire aperture having a color dependent upon the characteristics of the integrally colored annulus or of a colored film carried by the annulus. A distinctly pleasing appearance is thus provided in a ceiling or the like by the present downlighting luminaires, the quality of illumination being that of a luminous, colored glow surrounding a shaft of white light. It is to be understood, however, that the present luminaires can be configured such that colored light emanates from an interior reflector with white light emanating from the outer reflector. Still further, both reflectors can pass light of differing colors other than white therethrough with said colors either being the same or different from each other. 
     In a particular embodiment of the invention, the inner reflector is configured with a cylindrical sleeve fitting over a cylindrical innermost portion of said inner reflector, the sleeve having annular corrugations formed on outer surfaces thereof. The corrugations function with an annular O-ring to position the inner reflector at differing locations within the luminaire, outermost edges of the inner reflector being positionable, for example, flushly within the aperture of the luminaire or extending from said luminaire aperture at varying distances to provide an additional decorative function. 
     Lamping utilized in the several embodiments of the invention preferably comprises compact fluorescent lamps with one or more lamps being used depending upon luminaire configuration and size. Typically, compact fluorescent lamps are disposed in a horizontal orientation within the present luminaires in part as an accommodation to minimize luminaire height. In downlighting applications in particular, a luminaire housing mounting compact fluorescent lamping in horizontal orientations is preferably provided with openings for receiving such lamping in a conventional manner. Spring-loaded hinges are provided in preferred embodiments for mounting one or more lamp doors to the luminaire housing to cover openings formed in the luminaire housing, the openings providing clearance for the lamping. It is to be understood that lamping can be oriented vertically within a luminaire housing configured according to the invention without departing from the scope of the invention. Still further, a source of illumination producing white light, for example, can be employed for producing light passing through the inner reflector, light intended essentially only for passage through the outer reflector being produced in certain embodiments of the invention by means of a separate light source or sources such as light emitting diodes or LEDs. Since light emitting diodes are capable of producing colored light, that light directly produced by the light emitting diodes can be passed through a diffusing annulus located interiorly of the luminaire housing between inner and outer reflectors Such an annulus can be coated or provided with a film of a material which is capable of altering the color of light produced by LEDs used as a light source within a luminaire configured according to such an embodiment of the invention. In all embodiments of the invention, the light directed by the present luminaires into an environmental space can be customized as to coloration with a minimum of modification of structural elements of the luminaries. 
     Accordingly, it is an object of the invention to provide decorative luminaires capable of producing illumination of different character from different portions of an aperture of one of said luminaires, a central beam of light emanating from said luminaire typically providing a controlled distribution for usual lighting functions such as general lighting, accent lighting or the like, a second portion of that light emanating from said luminaire being characterized by differing visible properties such as differing coloration from the first-mentioned light, the second portion of the light typically being of a diffuse nature, thereby to provide a luminaire that functions to produce contrasting illumination of decorative appearance. 
     It is another object of the invention to provide decorative downlighting luminaires in particular having at least one reflector capable of assuming differing positions within a luminaire housing such that in at least one position a lower edge of the reflector is positioned flushly with luminaire aperture and in other positions is recessed into the luminaire housing or extends outwardly of the luminaire aperture, the luminaire producing decorative illumination typically characterized by a central beam of white light surrounded by an annulus of colored light providing a distinctive colored glow about a central beam of white light. 
     It is yet another object of the invention to provide decorative luminaires and particularly downlighting luminaires customizable as to coloration of illumination produced thereby and particularly luminaires capable of directing beams of differing coloration from apertures thereof. 
     Further objects and advantages of the invention will become more readily apparent in light of the following detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to the drawings and particularly to  FIG. 1 , portions of a decorative downlight luminaire seen generally at  10  are mounted substantially flushly with a ceiling  11 , the luminaire  10  directing an illuminating beam  12  from central portions thereof, the beam  12  preferably being white light intended to provide illuminating functions such as general lighting, task lighting, accent lighting and the like within an environmental space within which the luminaire  10  is mounted. As noted by the appearance of the illumination provided by the luminaire  10 , the beam  12  is seen to be surrounded by an annulus of light generally seen at  13 , the annulus  13  of light essentially surrounding the beam  12  as shown. The overall appearance and affect of the illumination provided by the luminaire  10  being that of a surreal glow reminiscent of impressionistic art and even art deco in its affect on observers thereof. The beam  12  of preferably white light appears in an actual installation of the luminaire  10  to be surrounded by the annulus  13 , the light emanating from the annulus  13  preferably being of a desired coloration and/or of a characteristic differentiated from the light of the beam  12 . In the installation as shown in  FIG. 1 , the central beam  12  appears to “float” within the colored annulus  13 . 
     Referring now to  FIG. 2  additionally to  FIG. 1 , an inner reflector  14  is seen to be centrally disposed within aperture  15  of the luminaire  10 , the inner reflector  14  having a lower peripheral annular edge  16 . Reflective surfaces  17  of the inner reflector  14  are typically taken to be parabolic in contour although other suitable shapes can be employed. The reflective surfaces  17  are preferably formed from or coated with a highly specular material such as anodized aluminum or the like. The inner reflector  14  is primarily intended to efficiently direct as much light through the luminaire aperture  15  as possible in order to lend efficiencies of operation to the luminaire  10 . Concentric with the inner reflector  14  is an outer reflector  18  only portions of which can be seen in  FIGS. 1 and 2 , the outer reflector  18  having an annular flange  20  disposed along a lower peripheral edge thereof, interior reflective surfaces  21  of the outer reflector  18  typically being formed of reflective white paint or the like. The outer reflector  18  functions primarily to reflect at least a portion of light emanating from lamping  22  (seen inter alia in  FIG. 3 ) that does not pass through the inner reflector  14  or directly out of the luminaire aperture  15  between outer surfaces of the inner reflector  14  and the reflective surfaces  21  of the outer reflector  18 . The outer reflector  18  is mounted to luminaire housing  24  by means of clips  26  as will be described in more detail hereinafter. The annular flange  20  of the outer reflector  18  functions primarily to provide a finished appearance about an opening (not shown) in the ceiling  11 , which opening is normally essentially co-planar with the aperture  15  of the decorative downlighting luminaire  10 . The housing  24  is further seen to be provided with an electrical compartment  28  such as is conventional in certain kinds of downlighting luminaires for housing electrical components and other conventional components such as lamp holders and the like for mounting of base portions of the lamping  22  inter alia. The luminaire  10  is intended to be mounted in a recessed fashion above a ceiling by mounting structure (not shown) of conventional structure, such mounting structure not being explicitly shown for ease of illustration. 
     The appearance of the decorative downlighting luminaire  10  can be caused to vary depending upon the position of the inner reflector  14  as can be seen in  FIGS. 3 through 5 . In  FIG. 3 , the lower edge  16  of the inner reflector  14  is disposed substantially flushly with lower edges of the outer reflector  18  and the annular flange  20  of the housing  24  and further with the plane of a ceiling (not shown in  FIG. 3 ). The position of the inner reflector  14  as seen in  FIG. 3  is that position providing the decorative affect of the luminaire  10  as seen in  FIG. 1 . Referring now to  FIG. 4 , the lower edge  16  of the inner reflector  14  is seen to be extended a certain distance below the aperture  15  of the luminaire  10 , thereby to extend slightly into the environmental space being illuminated by the luminaire  10 . As is seen in  FIG. 5 , the lower edge  16  of the inner reflector  14  is extended still further beyond the aperture  15  of the luminaire  10 , thereby to extend still further below a ceiling (not shown in  FIG. 5 ) and into the environmental space within which the luminaire  10  provides illumination. As can be seen in  FIGS. 3 through 5  inter alia, the location of the inner reflector  14  in the relative positions therein illustrated is caused to occur through a positioning of an O-ring  30  preferably formed of an elastomeric material, the O-ring  30  being manually displaceable to different locations best referred to as annular indentations  32  disposed between a series of spaced annular corrugations  34 . The O-ring  30  rests against an upper surface of an annulus element  36 , essentially a planar ring, the annulus element  36  having a central opening  38  formed therein through which upper portions of the inner reflector  14  extend, said upper portions of the reflector  14  carrying a substantially cylindrical sleeve  40  having an outer surface on which the annular indentations  32  and the spaced annular corrugations  34  are formed. In altering the location of the inner reflector  14  within the luminaire  10 , the resilient O-ring  30  is manually “rolled” over the cylindrical sleeve  40  and into that indentation  32  intended to locate the inner reflector  14  at a desired position as seen in  FIGS. 3 through 5 . 
     As is additionally seen in  FIGS. 7 and 8 , the inner reflector  14  is essentially formed of a reflector portion  42  and a surmounting cylindrical portion  44 , the cylindrical sleeve  40  essentially being mounted to the cylindrical portion  44  of the inner reflector  14 . As can be seen in the detail of  FIG. 8 , peripheral portions of the cylindrical portion  44  flare outwardly at outer peripheral edges thereof and essentially friction fit to upper inner surfaces of the cylindrical sleeve  40 , thereby to mount the cylindrical sleeve  40  to the inner reflector  14 . The inner reflector  14  can be configured to include the structure of the sleeve  40  integrally therewith without departing from the scope of the invention. 
     Referring now also to  FIGS. 11 and 12  in addition to  FIGS. 3 through 5  inter alia, the annulus element  36  is seen in greater detail and further in a perspective view in  FIG. 10 , the annulus element  36  essentially comprising a transparent or translucent element formed of glass or plastic, such as acrylic plastic or the like, the function of the annulus element  36  in addition to supporting the O-ring  30  and thus the inner reflector  14  in place within the luminaire  10  being to alter light from the lamping  22  that exits the aperture  15  of the luminaire  10  in the vicinity of the annulus of light at  13 . That light existing at  13  essentially passes between outer surfaces of the inner reflector  14  and the reflective surfaces  21  of the outer reflector  18 , this light so passing having been altered as to color and/or other characteristics by means of the annulus element  36  either by virtue of integral color provided in the annulus  36  such as by pigmentation of the glass or plastic material forming the annulus element  36  or by a provision of a coating or film such as the film  46  disposed either on upper or lower surfaces of the annulus element  36 . It is preferred according to the invention to use a translucent film such as the PVC film produced by Oracal USA, a division of LIG International, Inc., of Jacksonville, Fla., and such as is marketed under the trade name Series 8500 inter alia, transparent films also being usable. The films so identified are colored in a variety of colorations and provided with silk-matte surface finishes which inhibit undesired reflection. Further, film such as the film  46  can be provided with adhesive such as polyacrylate adhesives on one side thereof to permit easy attachment to a surface, preferably an under surface, of the annulus element  36 . The luminaire  10  can be readily customized as to coloration of the light emitted at the annulus  13  by simple removal of one of the annulus elements  36  having a film of one color and substitution of another annulus element having a film of another color. Particularly effective illumination is provided through the use of films having rich blue colorations which produce a blue annulus of light about a white shaft of light represented by the beam  12  as best seen in  FIG. 1 . However, it is to be understood that any desired color can be used. It is to be understood that the use of the film  46  as indicated above is preferable. However, coloration can be imparted to the annulus of light at  13  other than by the use of a film such as the film  46 . As is seen in  FIG. 10 , the annulus element  36  is seen to be spaced from the film  46 , the film  46  essentially being formed in an identical configuration such that the annulus element  36  and the film  46  can be mounted together to form a light-altering assembly  48 . It is further to be understood that either the annulus element  36  or the light-altering assembly  48  can be chosen to alter the wavelength of light passing therethrough in order to provide a desired characteristic of the light passing out of the luminaire  10  in the annulus at  13 , such materials capable of altering wavelength being known in the art. 
     As can best be seen in  FIGS. 3 through 5 , as well as in the exploded view of  FIG. 6  and further in the side elevations of  FIGS. 11 and 12 , lamping  22  can be seen to take the form of compact fluorescent lamps such as Triple Tube lamps as are available commercially. Such lamps are manufactured by General Electric and Sylvania inter alia. Luminaires configured according to the invention are typically provided with from one to three lamps, the embodiment shown in the drawings thus far referred to having two lamps  50 , both lamps typically being of the same wattage with usual wattages being between 18 and 57 watts. When a single lamp  50  is utilized, that lamp can be chosen to be a 57 watt lamp inter alia. In embodiments using three lamps (not shown), lamp wattages are selected between 18 watts and 42 watts in typical luminaires. As is seen in the drawings, the lamps  50  are seen to be horizontally mounted, horizontal orientations being preferred due to restrictions on the height of luminaires such as luminaire  10 . It is to be understood that vertically oriented lamping can be provided as is described hereinafter relative to a further embodiment of the invention. In preferred embodiments, light produced by a single tamping group such as the lamping  22  yields the light passing through both the inner reflector  14  and the outer reflector  18 . It is to be understood, however, that two separate light sources can be provided to accomplish these respective functions. It is further to be noted that a highly specular reflector (not shown) can be provided in upper portions of the housing  24  in order to direct a greater proportion of generated light through the aperture  15  of the luminaire  10 . However, introduction of a specular reflector in that region may generate lamp images of a character that would need to be accommodated in order to provide the best possible appearance of that light passing through the inner reflector  14 . Disposition of a lens or diffuser (not shown) at lower portions of the inner reflector  14  or even at innermost portions of the inner reflector  14  can be employed to obviate the visual effects of lamp images. However, use of diffusing lenses in this manner reduces lighting efficiency. 
     Referring now to  FIG. 9  as well as to  FIG. 6 , the outer reflector  18  is seen to be comprised of a body portion  52  to which the annular flange  20  is formed about lower perimetric edges thereof, inner surfaces of the body portion  52  essentially constituting the reflective surfaces  21  mentioned hereinabove. As is seen particularly in  FIGS. 11 and 12  with reference to  FIG. 6 , the clips  26  function to mount the outer reflector  18  to the housing  24 . An annular flange  54  formed about lower peripheral edges of a lower cylindrical body portion  56  of the housing  24  has spaced apertures (not shown) formed therein for receipt of portions of the clips  26 , free portions of the clips  26  contacting outer surfaces of the outer reflector  18  to hold said reflector  18  within the housing  24 . Clips  60  fixed to the housing  24  at one end by rivets  62  are disposed in spaced relation about inner surfaces of the housing  24  at upper portions of the cylindrical body portion  56  and extend upwardly and inwardly of interior cylindrical body portion  64  of the housing  24 , the body portion  64  having spaced elongated openings  66  formed therein in juxtaposed relation to the clip  60  such that free ends of the clips  60  can be biased outwardly through manual manipulation so as to release the annulus element  36  for replacement of the element  36  or for substitution of a film  46  of a differing color for a film previously mounted by the annulus element  36 , thereby to customize the luminaire  10  as to color of that light passing through the annulus at  13 . It is to be seen that the clips  60  each have a supporting ledge  68  against which the annulus element  36  rests. The clips  60  are formed of a spring steel or other resilient material so that the clips  60  bias inwardly to maintain the annulus element  36  in place but which can be bent outwardly as aforesaid to release the annulus element  36 . The housing  24  further comprises a body portion  70  having the shape of a spherical section, the body portion  70  being surmounted by a cylindrical end portion  72  into which the lamping  22  extends through a radially directed aperture  74  formed over outer surfaces of the end portion  72 . As also seen in  FIG. 13 , apertures  76  and  78 , respectively covered by lamp doors  80  and  82 , allow clearance for the lamping  22 , the lamp doors  80  and  82  being respectively mounted by spring-loaded hinges  84  and  86 . The mounting of the hinges  84  and  86  to permit operation of the lamp doors  80 ,  82  respectively is shown in  FIG. 13 . The lamp doors  80 ,  82  also function to close off the apertures  76  and  78  to prevent light leakage through said apertures  78 ,  79  and  80 . It is to be noted that inner surfaces of the housing  24  are preferably coated with a reflective white paint or the like, and especially inner surfaces of the body portion  70 , so that light incident on such surfaces is more efficiently reflected through either the inner reflector  14  or the outer reflector  18 . 
     Referring now to  FIG. 14 , a luminaire  88  configured according to another embodiment of the invention is provided with a vertically oriented incandescent light source  90 , the light source  90  providing white light that exits luminaire  88  through inner reflector  92 , the inner reflector  92  essentially being identical in conformation to the inner reflector  14  described hereinabove. The luminaire  88  is further configured to include an outer reflector  94  essentially identical to the outer reflector  18  described hereinabove. Between the reflectors  92 ,  94 , an annulus element  96  is disposed and mounted such as according to the description given above relative to the mounting of the annulus element  36 . The annulus element  96  can have a film  98  formed on a lower surface thereof which is identical to those films described as being suitable for use as the film  46  referred to hereinabove, for example. An array  100  of light emitting diodes  101  is provided in surmounting relationship to the annulus element  96  with the individual light emitting diodes  101  being preferably mounted in spaced relation just above the annulus element  96 . The LEDs  101  can be configured to produce light of differing color, it being possible to select light emitting diodes that emit green, blue and other colors so as to produce a colored annulus of light emanating from the luminaire  10  between the inner reflector  92  and the outer reflector  94 . In order to provide the richest quality of light from the LEDs  101 , it is typically desirable to close off upper portions of the inner reflector  92  such as with a header cap  99  and to dispose the light source  90  within the confines of the inner reflector  92  and mounted by socket  97 , When the LEDs  101  are chosen to be blue LEDs as is described in U.S. Pat. No. 5,640,792, it is possible to form the annulus element  96  and/or the film  98  of a material as is described in the aforesaid patent in order to alter the wavelength of light emitted by such light emitting diodes, thereby to produce an annulus of light of a wavelength altered from that light originally produced by the LEDs  101 . U.S. Pat. No. 5,640,792 is therefore incorporated hereinto by reference. It is also possible in the embodiment of  FIG. 14  to provide an annulus element  96  that diffuses the colored light produced by the LEDs  01 , no color being therefore imparted to light emanating from the luminaire  88  from any pigmentation contained in the annulus element  96 . 
     Referring now to  FIG. 15 , a luminaire  120  is seen to be similar to the luminaire  88  of  FIG. 14  with a primary exception being that an array of light emitting diodes  122  are mounted by an annular plate  124  between an inner reflector  126  and an outer reflector  128 . The annulus of colored light emanating from between the reflectors  126 ,  128  at  130  will exhibit a scalloped pattern on outer surfaces of the inner reflector  126  and on inner surfaces of the outer reflector  128 , an unusual affect that is decorative in nature additionally to the annulus of colored light that is apparent to a viewer at  130 . The annular plate  124  can be mounted within the interior of the luminaire  120  as is described herein relative to the mounting of the annulus element  36  of the embodiment shown in  FIGS. 1 through 13 . 
     The light emitting diodes chosen for use in the embodiments of  FIGS. 14 and 15  can be of a single color or can be of different colors depending upon the affect intended by a user of the luminaires  88  and  120 . 
     Referring now to  FIG. 16 , a luminaire  102  configured according to the invention is seen to be similar to the luminaire  10  with the exception of the provision of a disc  104  disposed in proximity to uppermost edges of an inner reflector  106 , the disc  104  acting to alter light produced by lamping  108  either by means of pigmentation provided in the disc  104  or by the disposition of a film  110  thereon, the film  110  being essentially identical to the film  46  described hereinabove. In the embodiment of  FIG. 16 , the luminaire  102  thus provides a colored light emanating from the inner reflector  106  and white light emanating from an annulus at  112  located between the inner reflector  106  and an outer reflector  114 . In most other respects, the luminaire  102  is otherwise identical to the luminaire  10 . In order to mount the inner reflector  106  within the luminaire  102 , an annular plate  116  is used in cooperation with an O-ring  118  essentially as is described herein relative to the cooperation of the annulus element  36  with the O-ring  30  relative to the embodiment shown in  FIGS. 1 through 13 . 
     As can be seen in  FIG. 17 , a luminaire is at  140  to be configured in a manner essentially identical to the embodiment shown in  FIGS. 1 through 13 . Inner reflector  142 , however, is formed with a layer  144  or coating of a colored anodized or similar material which yields a distinctive hue, such as a wheat coloration, thereby causing the beam of light exiting the inner reflector  142  to have a decorative appearance that is pleasing to the eye of an observer. The layer  144  could be formed of a colored, reflective paint or similar material. In other respects, an annulus of light emanating at  146  between the inner reflector  142  and an outer reflector  148  is colored and/or altered by means of annulus element  150  configured as has been described in detail herein relative to the annulus element  36 . An O-ring  152  can similarly be used in association with the annulus element  150  for mounting of said annulus element  150  within the luminaire  140  as has been described relative to corresponding structure described herein relative to the embodiment of the invention shown in  FIGS. 1 through 13 . 
     Referring now to  FIG. 18 , a luminaire is seen at  160  to be configured in a manner essentially identical to the embodiment of the invention shown in  FIGS. 1 through 13 . Outer reflector  162 , however, has inner surfaces thereof coated with a layer  164  of a colored, reflective anodized material or a reflective, colored paint or similar material, thereby causing coloration of an annulus of light emanating from between the outer reflector  162  and an inner reflector  166  at  168  to be caused by said layer  164 . The luminaire  160  has an annular plate  170  disposed between the outer reflector  162  and the inner reflector  166 , the plate  170  functioning in association with an O-ring  172  as noted herein to mount the inner reflector  166  within the luminaire  160 . However, the annular plate  170  is not provided as intended in the luminaire  160  to contribute to coloring of the annulus of light passing from the luminaire  160  at  168 . As an alternative, however, the plate  170  could take the form of the annulus plate  36  and associated film  46  as described herein relative to the embodiment of the invention shown in  FIGS. 1 through 13 . In such an alternative embodiment, both the layer  164  and an annulus element such as the annulus element  36 /film  46  would contribute to coloring of the light passing from the luminaire  160  at  168 . 
     As can now be seen with reference to  FIG. 19 , a luminaire is seen at  180  to be formed of an inner reflector  182  and an outer reflector  184 , outer surfaces of the inner reflector  182  and inner surfaces of the outer reflector  184  respectively having layers  186  and  188  formed thereon, the layers  186  and  188  being reflective, colored paint or a colored anodized material. Coloring of that light exiting from the luminaire  180  at  190  occurs due to the layers  186  and  188  rather than due to the function of structures such as the annulus element  36 /film  46  described herein relative to the embodiment of the invention shown in  FIGS. 1 through 13 . An annular plate  192  is seen to function in association with an O-ring  194  to mount the inner reflector  182  within the luminaire  180  as described relative to similar structure shown in  FIG. 18  inter alia. 
     Referring now to  FIG. 20 , a luminaire is seen at  200  to have an inner reflector  202  which takes the form of a fluted, prismatic reflective structure manufactured of a light-transmissive material such as glass or a “plastic” such as acrylic or polycarbonate or the like. An outer reflector  204  has a layer  206  of a reflective, colored paint or a colored anodized material formed on inner surfaces thereof, colored light thus produced within that space between the inner reflector  202  and the outer reflector  204  “bleeding” through the inner reflector  202  to colorize and thus alter the coloration of that light exiting the inner reflector  202  at  208 . That light exiting the luminaire at  210  is colored due to the function of the layer  206  as has been noted herein. Coloration of the light between the inner reflector  202  and the outer reflector  204  can alternatively or additionally be accomplished through use of an annulus element such as the annulus element  36 /film  46  referred to herein. However, annular plate  212  can be configured so as not to contribute to coloring of the light at  210  but can merely function in association with O-ring  214  to mount the inner reflector  202  within the luminaire  200  as has been described relative to corresponding structure described herein. 
     As can be seen in  FIGS. 21 and 22 , luminaires seen respectively at  220  and  240  can be configured according to the invention as pendent-mounted luminaires suspended from rigid tubular elements or flexible wires as is conventional in the art. The luminaire  220  has an inner reflector  222  mounted within an outer reflector  224 , the outer reflector  224  also conveniently serving as a housing for the luminaire  220 . An annulus of colored light exits the luminaire  220  at  226  as described herein relative to other embodiments of the invention, internal structure disposed within the outer reflector  224  being essentially identical to that described herein relative to downlighting embodiments of the invention. In the luminaire  220 , a central beam of white light preferably exits the inner reflector  222  and “floats” in an annular beam of colored light at  226 . In the luminaire  240  of FIG.  22 , an inner reflector  242  is carried by an outer reflector  244  that also serves as a housing, the outer reflector  244  taking the form of a prismatic reflector formed of a light-transmissive material such as glass or a “plastic” such as an acrylic or a polycarbonate as examples. In the luminaire  240 , a central beam of preferably white light exits the inner reflector  242  at  246  while a colored annulus of light is intended to exit the luminaire  240  between the inner reflector  242  and the outer reflector  244  at  240 . However, a decorative “glow” through the outer reflector  244  is also visible to an observer and creates an additional decorative affect. 
     It is to be understood that the scope of the present invention extends other than to the explicit descriptions of the specific embodiments of the invention, modifications and variations being apparent in light of the foregoing disclosure to those of ordinary skill in the art. As can be seen through reference to the embodiments of the invention that are explicitly described, it can be appreciated that the concepts of the invention can be embodied in varying kinds of luminaires including downlighting luminaires and pendent-mounted luminaires, as well as similar track-mounted luminaires and the like. Further, the various embodiments shown and described can be employed in such other kinds of luminaires. Accordingly, the scope of the invention is defined according to the recitations of the appended claims.
