- the motion-sensing monitor can deactivate the first set of illumination devices 18 when it activates the second set of illumination devices 58 , and vice versa.
- the second set of illumination devices can be activated and the first set of illumination devices 18 can be deactivated when the space is generally unoccupied by a user and the space generally lacks other illumination.
- the second set of illumination devices 58 can be deactivated and the first set of illumination devices 18 can be activated when the space is generally occupied by the user.
- the second set of illumination devices 58 can comprise other methods of operation.
- the second set of illumination devices 58 can emit a dynamic illumination event.
- the second set of illumination devices 58 upon triggering of the dynamic illumination event, generally can receive gradually increasing amounts of current, via the electrical connections, so that the intensity of the illumination emitted by the second set of illumination devices 58 can generally increase at approximately the same rate as the increase in current.
- the increase in illumination intensity can occur over a broad range of intensities and increments so that the space into which the system 10 is installed can gradually go from a general lack of illumination through gradually increasing intensities of illumination until the second set of illumination devices 58 emit a maximum amount of illumination.
- a microprocessor (not shown) can control the gradual increase in current to the second set of illumination devices 58 .

More specifically, in some embodiments, after activation, the general increase in current can increase at a generally lesser rate at a point more temporally proximal to activation than a point more temporally distal from activation. For example, relatively soon after activation, the rate of increase can comprise a generally lesser rate of current increase relative to a point closer to the pre-programmed maximum. After reaching the preprogrammed maximum, the amount of current can comprise a generally constant current.
- deactivation of the dynamic illumination event can comprise a generally immediate loss of current to the second set of illumination devices 58 .
- deactivation can comprise a relatively immediate withdrawal of current provided to the second set of illumination devices 58 .
- deactivation can comprise a gradual decrease in current to the second set of illumination devices 58 so that the intensity of the second set of illumination devices generally correspondingly decreases until substantially less illumination radiates from the second set of illumination devices 58 .
- the illumination emitted by the second set of illumination devices 58 during the dynamic illumination event can comprise a range of colored illumination.
- the color can be any color, include blue, green, purple, amber, or any other color.
- the range of colored illumination can include variations in hues of the same color. For example, if the colored illumination is blue, then color emitted by the second set of illumination devices 58 upon initial activation of the dynamic illumination event can be generally a darker hue of blue, and as the current increases, the color can become a generally lighter hue of blue.
- the system 10 can include the capability to emit more than one color.
- the user can select which color he or she prefers for the dynamic illumination event from any color that the system 10 can display.
- the system 10 can include four colors from which the user can chose, although in other embodiments, the system can include any number of colors that the manufacturer or user desires.

- the second set of illumination devices 58 can provide illumination both when the user is and/or is not in the space to be illuminated.
- the second set of illumination devices 58 can emit a generally low-level intensity of illumination so that the system 10 can function as a night light, similar to some of the previously mentioned embodiments. In some embodiments, this can be mediated, at least partially by the motion sensing monitor (e.g. the system 10 can function as a night light when there is little to no movement in the space).
- the second set of illumination devices 56 can be controlled by a timer to determine when the low-intensity illumination should be emitted.

Additionally, in some embodiments, the one or more snap-fit features can be supplemented or largely replaced by any variety of couplings, such as screws, grille springs, bolts, rivets, pins, clamps, glue or other adhesive, and any other similar coupling. In some embodiments, themain housing 12 and thegrille 32 can be further secured through other coupling practices such as welding, soldering, brazing, adhesive or cohesive bonding material, any combination of the foregoing, or any other similar coupling practice. - Referring to
FIGS. 1-3 , in some embodiments, themain housing 12 can include one or more lips, flared edges, flanges, or other features to which thegrille 32 can be coupled. In some embodiments, themain housing 12 can include a first set ofperipheral flanges 34 to which thegrille 32 can be coupled. In other embodiments, thegrille 32 can be shaped and dimensioned to be received within themain housing 12 and thegrille 32 can be coupled to themain housing 12 using any of the above described methods. In some embodiments, thegrille 32 and themain housing 12 can include apertures through which fasteners can be passed to couple thegrille 32 and themain housing 12. Any of the previously described couplings can be used to couple thegrille 32 and themain housing 12. - In some embodiments of the invention, the
grille 32 can include theapertures 20. In some embodiments, theapertures 20 can extend across aninlet 36, which can be defined by themain housing 12. Theapertures 20 can be used for receiving a flow of air. The plurality ofapertures 20 can be located anywhere on thegrille 32. In some embodiments, the location of theapertures 20 can be at least partially determined by airflow path(s) which can be available from theapertures 20, through theinlet 36, and into the ventilatingassembly 14. In some embodiments, theapertures 20 can be located substantially around a perimeter of aregion 38 of thegrille 32. In some embodiments, the location of theapertures 20 can be selected substantially based on aesthetics, functionality, and other considerations that can be important to a user and/or a manufacturer. - As best seen in
FIGS. 2 and 3 , in some embodiments, theapertures 20 can guide air into thesystem 10. Air can include moisture, steam, exhaust, smoke, effluent, or anything similar. In some embodiments, after passing through theapertures 20 and entering theinlet 36 of themain housing 12, the air can enter the ventilatingassembly 14, which can be included in themain housing 12, as discussed below. In some embodiments, the ventilatingassembly 14 can be operable to discharge the airflow to another location, such as an attic, outside of the structure in which thesystem 10 can be secured, and/or to a duct network. Further, the airflow can be discharged from theventilation outlet 22 of themain housing 12, in some embodiments. - As shown in
FIGS. 10A and 10B , in some embodiments, thegrille 32 can comprise different configurations. In some embodiments, thegrille 32 can comprise asupport frame 81 and at least onesupport flange 84. In some embodiments, thegrille 32 can comprise a plurality ofsupport flanges 84. In some embodiments, at least a portion of thesupport flanges 84 can be coupled to thesupport frame 81 using any of the previously mentioned coupling techniques. In some embodiments, at least a portion of thesupport flanges 84 can be substantially integral with thesupport frame 81. For example, in some embodiments, thegrille 32 can comprise a single sheet of metal and thesupport frame 81 andsupport flanges 84 can be stamped so that thegrille 32 comprises a desired configuration. Moreover, in some embodiments, thegrille 32 can be formed in a mold so thatsupport frame 81 and at least some of thesupport flanges 84 are generally integrally formed. - As previously mentioned, the
grille 32 can be coupled to themain housing 12 in a number of different ways. For example, in some embodiments, thesupport frame 81 can comprise at least oneclip 86, as shown inFIG. 10A . In some embodiments, thesupport frame 81 can comprise a plurality ofclips 86 that can be positioned around an outer perimeter of thegrille 32. By way of example only, in some embodiments, thegrille 32 can comprise a substantially square shape and theclips 86 can be positioned on two of the four sides of thegrille 32. Although, in other embodiments, thegrille 32 can comprise other shapes, such as, but not limited to square, rectangular, regular or irregular polygonal, any shape generally corresponding to themain housing 12, etc. In some embodiments, theclips 86 can be configured and arranged to engage elements of the main housing 12 (not shown) to couple thegrille 32 to a portion of themain housing 12. In some embodiments, theclips 86 can also support thegrille 32. - In some embodiments, the
support frame 81 can comprise a plurality ofwalls 88, anupper flange 90, and alower flange 92. Referring toFIGS. 10A and 10B , in some embodiments, thewalls 88 can define a perimeter of thegrille 32 and theupper flange 90 can be coupled to thewalls 88 in any of the previously mentioned coupling manners. In some embodiments, theupper flange 90 can be substantially integral with the walls 88 (e.g., theflange 90 and thewalls 88 are formed as a substantially integral element). In some embodiments,upper flange 90 can laterally extend from a portion of thewalls 88 and, during assembly, can engage a portion of themain housing 12 to at least partially provide support for thegrille 32. - In some embodiments, the
lower flange 92 can extend from a portion of thewalls 88 substantially opposite theupper flange 90. Moreover, in some embodiments, thelower flange 92 can at least partially define theaperture 20. For example, as shown inFIGS. 10A and 10B , in some embodiments, thelower flange 92 can extend in a lateral direction substantially opposite from theupper flange 90 and theaperture 20 can be disposed between portions of thelower flange 92. - Moreover, in some embodiments, the
support flanges 84 can at least partially extend into a portion of theaperture 20 from thelower flange 92. In some embodiments, thesupport flanges 84 can extend from thelower flange 92 in multiple locations. As shown inFIGS. 10A and 10B , for example, in some embodiments, thelower flange 92 can comprise a substantially square configuration and thesupport flanges 84 can extend from each of the sides of the square. Although, in other embodiments, thelower flange 92 can comprise other shapes, and, thesupport flanges 84 can extend in different manners to at least partially correspond to the shape of thelower flange 92. - In some embodiments, at least a portion of the
support flanges 84 can comprise different sections. For example, in some embodiments, thesupport flanges 84 can comprise different planes. As shown inFIGS. 10A and 10B , in some embodiments, afirst region 94 of at least portion of at least some of thesupport flanges 84 can linearly extend from thelower flange 92 so that thesupport flange 84 and thelower flange 92 are in substantially the same plane. In some embodiments, as thesupport flanges 84 extend toward a center of thegrille 32, thesupport flanges 84 can extend to a different plane. For example, as shown inFIGS. 10A and 10B , in some embodiments, thesupport flanges 84 can comprise asecond region 96 that is oriented substantially parallel to at least a portion of thewalls 88. In some embodiments, thesecond region 96 can extend away (e.g. up, down, and/or angled) from thefirst region 94. Moreover, in some embodiments, at least some of thesecond regions 96 can be at least partially angled and need not be substantially linear. In some embodiments, at least some of thesupport flanges 84 can comprise athird region 98 extending from thesecond region 96. In some embodiments, thethird region 98 can lie in different plane relative to thefirst region 94, but, in some embodiments, thethird region 98 can be substantially parallel to thefirst region 94. As shown inFIGS. 10A and 10B , in some embodiments, thethird region 98 can lie in a plane substantially above the first region, however, in some embodiments, thethird region 98 can lie in plane substantially below or substantially congruent to the plane of thefirst region 94. - Referring to
FIGS. 2 and 3 , in some embodiments, portions of thegrille 32 adjacent to theregion 38, which can define the plurality ofapertures 20, can include a substantially curved area. Substantially curved can include arched, arced, angled, bent, bowed, curled, rounded, warped, or any other deviation from substantially planar. In other embodiments, the portions of thegrille 32 which can define the plurality ofapertures 20 can be substantially planar. - According to some embodiments, the
region 38 can be located in a generally central area of thegrille 32. In other embodiments, theregion 38 can be located generally anywhere on thegrille 32. In yet other embodiments, theregion 38 can includemultiple regions 38 located in either generally central areas of thegrille 32 or anywhere on thegrille 32. In some embodiments, theregion 38 can take a generally annular shape. In other embodiments, theregion 38 can take other shapes, including square, rectangular, polygonal, spherical, elliptical, or any other shape. - In some embodiments of the invention, the
region 38 can include a horizontal plane and thegrille 32 can include a horizontal plane. In some embodiments, the horizontal plane of theregion 38 can be substantially parallel to the horizontal plane of thegrille 32, but the two horizontal planes need not be congruent. More specifically, in some embodiments, theregion 38 can be generally elevated with respect to thegrille 32. In other embodiments, theregion 38 can be generally recessed with respect to thegrille 32. In other embodiments, the horizontal planes of both thegrille 32 and theregion 38 can be substantially congruent so that theentire grille 32 can be generally planar. - As shown in
FIG. 2 , in some embodiments, the portions of thegrille 32 which can include the substantially curved area can be curved in a direction so that thegrille 32 and theregion 38 can contact each other. In some embodiments where theregion 38 can be elevated with respect to thegrille 32, the substantially curved area can curve in a generally upward direction so that theregion 38 and thegrille 32 can contact each other. More specifically, theregion 38 can reside as a plateau connected to thegrille 32, but on a different horizontal plane with the substantially curved area included between the two elements. In some embodiments where theregion 38 can be recessed with respect to thegrille 32, the substantially curved area can curve in a generally downward direction so that theregion 38 and thegrille 32 can contact each other. In other embodiments, the substantially curved area can be substantially planar so that thegrille 32 and the region can be generally positioned in one horizontal plane. In some embodiments, thegrille 32 and theregion 38 can both be formed in one unit so that thegrille 32 and theregion 32 are integral. In some embodiments, thegrille 32 and theregion 32 can be formed from at least two different subunits and coupled together. Thegrille 32 and theregion 32 can be coupled using any of the methods described above. - Referring to
FIG. 3 , in some embodiments of the invention, theregion 38 can include alamp aperture 40. Thelamp aperture 40 can be defined in a generally central location within theregion 38, in some embodiments. In other embodiments, thelamp aperture 40 can be defined anywhere within theregion 38 or thegrille 32. In some embodiments, thelamp aperture 40 can be generally annular, however thelamp aperture 40 also can be generally square, rectangular, polygonal, spherical, elliptical, or any other shape. In some embodiments the shape of thelamp aperture 40 can be selected based on the shape of thelamp housing 16. - In some embodiments, the
lamp housing 16 can be shaped and dimensioned to be received by thelamp aperture 40. In some embodiments, thelamp housing 16 can include a heat-resistant material, heat shielding, and/or a reflective surface to inhibit heat from contacting various components of thesystem 10. In some embodiments, the reflective surface can generally direct light out thesystem 10. In some embodiments, thelamp aperture 40 can generally support, hold, or sustain thelamp housing 16. In some embodiments, thelamp aperture 40 can include a mountingflange 42 which can be used to support thelamp housing 16. The mountingflange 42 can be located substantially entirely around the inner diameter of thelamp aperture 40 and can be integral with thelamp aperture 40. In other embodiments, the mountingflange 42 can be a plurality of mounting flanges located around the inner diameter of thelamp aperture 40. - As shown in
FIGS. 3-4 , in some embodiments, thelamp housing 16 can be secured to the mountingflange 42 by one or more snap-fit features on thelamp housing 16 and/or the mountingflange 42. Additionally, in some embodiments, the one or more snap-fit features can be supplemented or largely replaced by any variety of coupling, such as screws, bolts, rivets, pins, clamps, glue or other adhesive, and any other similar fastener. In some embodiments, thelamp housing 16 and the mountingflange 42 can be further secured through other coupling practices such as welding, soldering, brazing, adhesive or cohesive bonding material, any combination of the foregoing, or any other similar coupling practice. - Referring to
FIG. 3 , in some embodiments, thelamp housing 16 can include one or more lips, flared edges, flanges, or other features to which the mountingflange 42 can be coupled. In some embodiments, thelamp housing 16 can include a second set ofperipheral flanges 44 to which the mountingflange 42 can be attached. In some embodiments, the mountingflange 42 can include a set ofpins 46 which can be received by a set of apertures included on the second set ofperipheral flanges 44. In some embodiments, the connection between thepins 46 and the apertures of theflanges 44 can be further secured using any of the previously mentioned coupling methods. Further, in some embodiments, the mountingflange 42 and thelamp housing 16 can include apertures through which any of the above-discussed fasteners I couplers can be passed to secure the mountingflange 42 to thelamp housing 16. In some embodiments, thelamp housing 16 can be directly coupled to theregion 38 and/or thegrille 32 in any suitable manner. Further, in some embodiments, thelamp housing 16 can be directly coupled to themain housing 12 in any suitable manner. - In some embodiments, the
lamp housing 16 can include theelectrical sockets 30 and the first set ofillumination devices 18, although some embodiments can include only oneelectrical socket 30 and oneillumination device 18. In some embodiments, theelectrical sockets 30 can be connected to the electrical components. Theillumination devices 18 can contact theelectric sockets 30, and, in some embodiments, when activated by the user, theillumination devices 18 can provide illumination to the room, area, or space. In some embodiments, theillumination devices 18 can include incandescent, fluorescent, compact fluorescent, halogen, and other lights and lamps. Further, these lights can be flood lights, globe lights, light-emitting diodes (LEDs), or other similar lighting apparatuses, including a combination of any of the above. - Referring to
FIGS. 2-3 , in some embodiments, theillumination devices 18 can be configured to operate separately from one another. In some embodiments, a first set ofillumination devices 18 can be configured to emit either a brighter or duller light than the remainder of the first set ofillumination devices 18. Also, in some embodiments, theillumination devices 18 can be configured in any conventional manner to have one or more dimmed settings or can be controllable in a range of brightness. - In some embodiments, the
region 38 can include a set ofstep members 48. In some embodiments, the set ofstep members 48 can be onestep member 48, however, m some embodiments the set ofstep members 48 can be more than onestep member 48, such as fourstep members 48. In some embodiments, thestep members 48 can outwardly extend from theregion 38. In some embodiments, thestep members 48 can outwardly extend directly from thegrille 32. Thestep members 48 can take a generally rectangular form in some embodiments, although in some embodiments, thestep members 48 can take other forms, including square, oval, polygonal, elliptical, or any other shape. In some embodiments, thestep members 48 can be integral with theregion 38 or thegrille 32. In some embodiments, thestep members 48 can be separate subunits of thesystem 10 and can be coupled to theregion 38 or thegrille 32 in any suitable manner. - As illustrated in
FIGS. 3 and 4 , in some embodiments, thestep members 48 can include asupport flange 50, although not all stepmembers 48 included in thesystem 10 need to include asupport flange 50. In some embodiments, thesupport flange 50 can be positioned on eachstep member 48 at an end which generally can be the most radially distal relative to theregion 38. In some embodiments, thesupport flange 50 can be positioned anywhere along the length of thestep members 48. In some embodiments, thesupport flange 50 can be integral with thestep members 48, however, in other embodiments, thesupport flange 50 can be coupled to thestep members 48 in any suitable manner, which can include using any of the coupling techniques described above. - Referring now to
FIG. 4 , in some embodiments, each of thestep members 48 can include asupport slot 52. Thesupport slot 52 can be defined by an area along a surface of thestep members 48 near thesupport flange 50. In some embodiments, thesupport slot 52 can be sized to support aplate 54, as described in further detail below. Thesupport slot 52 and thesupport flange 50 together can, at least partially, enable installation of theplate 54 onto thesystem 10. In some embodiments, thesupport slot 52 can be any size which can be coordinated with any functionality the user and/or manufacturer desires. In other embodiments, theplate 54 can be installed by any other suitable methods and thesupport slots 52 can be absent. - Referring to
FIG. 4 , in some embodiments, an area of each of thestep members 48 adjacent to thesupport slots 52 can include anillumination aperture 56. In some embodiments, theillumination apertures 56 can be located relatively centrally with respect to thesupport slots 52, however, in other embodiments, theillumination apertures 56 can be located anywhere within thesupport slots 52. In other embodiments, theillumination apertures 56 can be located anywhere along thestep members 48. In some embodiments, there can be any number ofillumination apertures 56 on thesystem 10, including one perstep member 48, two perstep member 48, three perstep member 48, and so forth. Further, in some embodiments, some or all of thestep members 48 can lackillumination apertures 56. - In some embodiments, the
illumination apertures 56 can contain electrical connections which can be used to provide power to a second set ofillumination devices 58. The electrical connections can be positioned substantially within thestep members 48. More specifically, in some embodiments, thestep members 48 can be at least partially hollow or thestep members 48 can contain a recess within them. In some embodiments, the electrical connections can be positioned within the hollow area of thestep members 48. In some embodiments, the electrical connections can be part of a larger network of electrical components which can be connected to a user interface which the user can use to control thesystem 10. In some embodiments, thestep members 48 can be substantially solid (i.e., substantially lacking any hollow areas) and the electrical connections can be positioned elsewhere on thesystem 10. - In some embodiments, the
illumination apertures 56 can include the second set ofillumination devices 58. The second set ofillumination devices 58 can by of any type suitable to illuminate a room, area, space, or can be used to illuminate theplate 54. In some embodiments, the second set ofillumination devices 58 can comprise LEDs, although, in some embodiments, the second set ofillumination devices 58 can include incandescent, fluorescent, compact fluorescent, halogen, or any other type of illuminating apparatuses, including a combination of any of the above. In some embodiments, the number ofillumination apertures 56 and the number of the second set ofillumination devices 58 can be substantially the same (i.e., four illumination apertures and four illumination devices). In other embodiments, the number ofillumination apertures 56 and the number of the second set ofillumination devices 58 can be different, although in some embodiments, more than oneillumination device 58 can be installed within oneillumination aperture 56. Further, one or more of the second set ofillumination devices 58 can be configured in any conventional manner to have one or more dimmed settings or to be controllable in a range of brightness. - Referring to
FIG. 8 , in some embodiments, the second set ofillumination devices 58 can comprise a lighting strip orribbon 82. In some embodiments, thestep members 48, or anannular structure 78 that can be generally positioned on or in thegrille 32 orregion 38, can support theribbon 82 to provide more even lighting about the periphery of a portion of theregion 38 or thegrille 32. In some embodiments, theribbon 82 can comprise incandescent, fluorescent, compact fluorescent, halogen, and other lights and lamps. Further, theribbon 82 can comprise flood lights, globe lights, LEDs, or other similar lighting apparatuses, including a combination of any of the above. In some embodiments, electrical connections can be coupled to theribbon 82 so that theribbon 82 can receive power. In some embodiments, the electrical connections can be part of a larger network of electrical components that can be connected to a user interface which the user can use to control thesystem 10. - In some embodiments of the invention, the second set of
illumination devices 58 can be configured to operate independently of the first set ofillumination devices 18. In some embodiments, the second set ofillumination devices 58 can be configured to substantially automatically emit illumination when the area around thesystem 10 substantially lacks illumination (e.g., operate as a “night light”). In some embodiments, the second set ofillumination devices 58 can be configured to emit illumination at the command of the user. The command of the user can include the user manually activating the second set ofillumination devices 58, the user pre-programming automatic activation of the second set ofillumination devices 58, the user pre-selecting times of the day for activation of the second set ofillumination devices 58, or any other user-based commands. In some embodiments, both thefirst set 18 and the second set ofillumination devices 58 can be configured to illuminate substantially the same space at substantially the same time. - Referring to
FIG. 2 , in some embodiments, the second set ofillumination devices 58 can be configured to operate in cooperation with the first set ofillumination devices 18. In some embodiments, thefirst set 18 and the second set ofillumination devices 58 can be configured to be, at least partially, controlled by a motion-sensing monitor. In some embodiments, the motion sensing monitor can activate the first set ofillumination devices 18 when it detects any general movement and the monitor can activate the second set ofillumination devices 58 after no movement is detected for any chosen duration. In some embodiments, the motion-sensing monitor can deactivate the first set ofillumination devices 18 when it activates the second set ofillumination devices 58, and vice versa. Further, in some embodiments, the second set of illumination devices can be activated and the first set ofillumination devices 18 can be deactivated when the space is generally unoccupied by a user and the space generally lacks other illumination. Conversely, the second set ofillumination devices 58 can be deactivated and the first set ofillumination devices 18 can be activated when the space is generally occupied by the user. - In some embodiments, the second set of
illumination devices 58 can comprise other methods of operation. For example, in some embodiments, the second set ofillumination devices 58 can emit a dynamic illumination event. In some embodiments, upon triggering of the dynamic illumination event, the second set ofillumination devices 58 generally can receive gradually increasing amounts of current, via the electrical connections, so that the intensity of the illumination emitted by the second set ofillumination devices 58 can generally increase at approximately the same rate as the increase in current. The increase in illumination intensity can occur over a broad range of intensities and increments so that the space into which thesystem 10 is installed can gradually go from a general lack of illumination through gradually increasing intensities of illumination until the second set ofillumination devices 58 emit a maximum amount of illumination. In some embodiments, a microprocessor (not shown) can control the gradual increase in current to the second set ofillumination devices 58. Further, in some embodiments of the invention, the gradual increase can be provided by different power modulation techniques, including pulse-width modulation. - Additionally, in some embodiments, the rate of gradual increase in the amount of current to the second set of
illumination devices 58 can comprise a generally constant ramp slope. For example, after activation, the gradual increase in current provided to the second set ofillumination devices 58 can comprise a generally constant increase until the amount of current can reach the pre-programmed maximum and then the amount of current can comprise a generally constant current. - In some embodiments, the general increase in the amount of current can comprise a generally gradual onset ramp slope. More specifically, in some embodiments, after activation, the general increase in current can increase at a generally lesser rate at a point more temporally proximal to activation than a point more temporally distal from activation. For example, relatively soon after activation, the rate of increase can comprise a generally lesser rate of current increase relative to a point closer to the pre-programmed maximum. After reaching the preprogrammed maximum, the amount of current can comprise a generally constant current.
- In some embodiments, deactivation of the dynamic illumination event can comprise a generally immediate loss of current to the second set of
illumination devices 58. For example, deactivation can comprise a relatively immediate withdrawal of current provided to the second set ofillumination devices 58. In some embodiments, deactivation can comprise a gradual decrease in current to the second set ofillumination devices 58 so that the intensity of the second set of illumination devices generally correspondingly decreases until substantially less illumination radiates from the second set ofillumination devices 58. - In some embodiments of the invention, the illumination emitted by the second set of
illumination devices 58 during the dynamic illumination event can comprise a range of colored illumination. The color can be any color, include blue, green, purple, amber, or any other color. Further, in some embodiments, the range of colored illumination can include variations in hues of the same color. For example, if the colored illumination is blue, then color emitted by the second set ofillumination devices 58 upon initial activation of the dynamic illumination event can be generally a darker hue of blue, and as the current increases, the color can become a generally lighter hue of blue. - Additionally, in some embodiments, the
system 10 can include the capability to emit more than one color. In some embodiments, the user can select which color he or she prefers for the dynamic illumination event from any color that thesystem 10 can display. In some embodiments, thesystem 10 can include four colors from which the user can chose, although in other embodiments, the system can include any number of colors that the manufacturer or user desires. - In some embodiments, the user can use a selection actuator (not shown) to select the color of the dynamic illumination event. In some embodiments, the selection actuator can be a dip switch, but in other embodiments, the selection actuator can be a rotary switch, or any other suitable device. In some embodiments, the selection actuator can be positioned substantially within the
lamp housing 16, themain housing 12, thegrille 32, or generally anywhere in or on thesystem 10, but in other embodiments, the selection actuator can be installed in a remote location. - In some embodiments, the second set of
illumination devices 58 can provide illumination both when the user is and/or is not in the space to be illuminated. For example, in some embodiments, when the user is not present in the space to be illuminated, the second set ofillumination devices 58 can emit a generally low-level intensity of illumination so that thesystem 10 can function as a night light, similar to some of the previously mentioned embodiments. In some embodiments, this can be mediated, at least partially by the motion sensing monitor (e.g. thesystem 10 can function as a night light when there is little to no movement in the space). Additionally, in some embodiments, the second set ofillumination devices 56 can be controlled by a timer to determine when the low-intensity illumination should be emitted. In some embodiments, upon detecting the presence of the user (e.g., via the motion sensing monitor, a user-actuated switch, and/or a timer), the second set ofillumination devices 58 can emit the dynamic illumination event or can substantially immediately begin emitting a greater intensity illumination so that at least a portion of the room is substantially illuminated (e.g., thesystem 10 can provide both quiescent and/or task illumination). - In some embodiments, the system can include the
plate 54. In some embodiments, theplate 54 can be formed from glass, acrylic, injection-molded polymers, or any other similar material. In some embodiments, the plate can be formed such that it is substantially transparent. In other embodiments, the plate can be formed such that it can be substantially translucent, opaque, or any other light-transmissive state within the range of any of the above. Further, in some embodiments, theplate 54 can include different regions which can include different light-transmissive properties. - In some embodiments, the
plate 54 can be generally colorless (i.e., lacking all tint). In other embodiments, theplate 54 can include a tint. Further, in some embodiments the tint color can include green, blue, red, orange, violet, yellow, or any other color or combination of colors (not shown). - In some embodiments, the
plate 54 can be formed so that it can take a generally annular shape. In other embodiments, however, theplate 54 can take any shape, including, but not limited to a square, rectangle, polygon, ellipse, oval, or any other shape. Also, in some embodiments, theplate 54 can have a substantially irregular shape. - In some embodiments, the
plate 54 can be of a size substantially similar to thegrille 32. In some embodiments, however, theplate 54 and thegrille 32 can be of generally different sizes. Theplate 54 can be either a larger size or a smaller size than thegrille 32. - In some embodiments, the
plate 54 can include a substantially non-textured or smooth surface. In other embodiments, theplate 54 can include a non-homogenous surface so that the surface of theplate 54 can be, at least partially, textured. In some embodiments, theplate 54 can be manufactured as a single unit. In some embodiments, theplate 54 can be manufactured as multiple units and those multiple units can be coupled using any one or combination of the coupling techniques discussed above. - Referring to
FIGS. 3 and 6 , according to some embodiments of the invention, theplate 54 can include aplate aperture 60. In some embodiments, theplate aperture 60 can be located substantially centrally on theplate 54. In other embodiments, theplate aperture 60 can be located anywhere along theplate 54. In some embodiments, theplate aperture 60 can take a generally annular shape so that, with inclusion of theplate aperture 60 in a generally annular-shapedplate 54, theplate 54 can take a generally ring-shaped appearance. In other embodiments, theplate aperture 60 can take any other regular or irregular shape. - In some embodiments, walls of the
plate aperture 60 can include a generally smooth, non-textured surface. As seen inFIG. 6 , in other embodiments, the walls of theplate aperture 60 can include a generally texturedsurface 62. In some embodiments, thetextured surface 62 can include a generally saw-toothed texture, as can be seen inFIG. 6 . In some embodiments, thetextured surface 62 can substantially extend around the entire circumference of theplate aperture 60. In some embodiments, thetextured surface 62 can be localized only to some regions of the walls of theplate aperture 60, as shown inFIG. 2 . The textured surface can help to diffuse light and provide a more even illumination pattern in some embodiments of the invention. - In some embodiments, the walls of the
plate aperture 60 can include a set of mountingnotches 64. In some embodiments, the set of mountingnotches 64 can be of a generally semicircular shape, although in other embodiments the set of mountingnotches 64 can be a shape that is generally square, rectangular, elliptical, oval, or any other regular or irregular shape. In some embodiments, the set of mountingnotches 64 can be substantially equidistantly spaced around the circumference of theplate aperture 60, although in other embodiments, the set of mountingnotches 64 can be spaced in any manner desired. In some embodiments, the number of the set of mountingnotches 64 can be the same as the number ofstep members 48. In other embodiments, the numbers of mountingnotches 64 andstep members 48 can be different. - Referring to
FIG. 2 , in some embodiments, the set of mountingnotches 64 can be used to couple theplate 54 to thegrille 32. In some embodiments, theplate 54 can be positioned so that each of thesupport flanges 50 substantially align with an area generally adjacent to each of the mountingnotches 64. In some embodiments, once aligned, theplate 54 can be moved so that theplate 54 moves with respect to thesupport flanges 50. In some embodiments, once the mountingnotches 64 are moved away from thesupport flanges 50, theplate 54 can now be largely supported by thesupport flanges 50 and thesupport slots 52. In some embodiments, the movement of theplate 54 can be a rotation, twist, revolving, or other similar movement. - In some embodiments, the
plate 54 can be coupled to thegrille 32 in other manners. As shown inFIGS. 11A and 11B , in some embodiments, theplate 54 can be coupled to thesupport flanges 84. In some embodiments, at least some of thesupport flanges 84 comprise aplate coupling aperture 100 disposed through portions of thesecond region 96 and thethird region 98, as shown inFIGS. 10A and 10B . In some embodiments, thecoupling apertures 100 can function to couple theplate 54 to the grille 32 (e.g., the support flanges 84). For example, in some embodiments, at least some clips (not shown), which can be integral or coupled to theplate 54, can be used to couple theplate 54 to thecoupling apertures 100. In other embodiments, theplate 54 can be coupled to thegrille 32 in any of the previously mentioned coupling manners. Moreover, in some embodiments, at least a portion of theplate 54 can be in a plane that is substantially congruent with a plane of theupper flange 90, as shown inFIGS. 9 , 11A and 11B. - In some embodiments, after coupling an air path can be defined between the

plate 54 can comprise other configurations. As shown inFIGS. 11A-12 , in some embodiments, theplate 54 can comprise arecess 102 around at least a portion of an inner perimeter of theplate 54. For example, as shown inFIG. 12 , in some embodiments, therecess 102 can be positioned substantially adjacent to an outer perimeter of the plate 54 (e.g., therecess 102 is almost at an edge of the plate 54). Although, in other embodiments, therecess 102 can be positioned in other locations on and/or through theplate 54. - In some embodiments, the
recess 102 can comprise a shape substantially similar to the plate's 54 shape. For example, as shown inFIG. 12 , in some embodiments, theplate 54 can comprise a substantially square shape and, accordingly, therecess 102 can comprise a substantially square shape. Moreover, as previously mentioned, in some embodiments, theplate 54 can comprise any number of shapes, and accordingly, therecess 102 can comprise any number of shapes. Furthermore, in some embodiments, therecess 102 need not comprise a shape similar to theplate 54. For example, theplate 54 can comprise a substantially square shape, and therecess 102 can comprise any other shape (e.g. annular). - In some embodiments, the
recess 102 can comprise a groove, a notch, a depression, an indentation, etc. In some embodiments, at least a portion of therecess 102 can extend through an entire thickness of theplate 54. In some embodiments, theplate 54 can be formed with therecess 102, and in other embodiments, therecess 102 can be machined or otherwise disposed within theplate 54. Additionally, in some embodiments, at least a portion of an interior surface of therecess 102 can comprise thetextured surface 62. - In some embodiments, at least a portion of the second set of
illumination devices 58 can be coupled to theplate 54. In some embodiments, the second set ofillumination devices 58 can be coupled to theplate 54 using any of the previously mentioned coupling techniques, including disposing thedevices 58 within at least a portion of therecess 102. For example, as shown inFIG. 13 , in some embodiments, theribbon 82 can be at least partially positioned within therecess 102. In some embodiments, theribbon 82 can comprise any of the previously mentioned lighting configurations. In some embodiments, electrical connections can be coupled to theribbon 82 so that theribbon 82 can receive power.

plate 54, the second set ofillumination devices 58, and therecess 102 can be configured and arranged to direct illumination in multiple directions. In some embodiments, the second set ofilluminations 58 can be disposed in therecess 102 so that that illumination is centrally directed, with respect to theplate 54. For example, in some embodiments, the second set ofillumination devices 58 can be positioned so that their illumination is directed inward and diffuses through theplate 54, which can produce a generally illuminatedplate 54. In some embodiments, the second set ofillumination devices 58 can be disposed in therecess 102 in other manners so that their illumination is directed in substantially any direction desired by the manufacturer and/or end user. - In some embodiments, a
panel 104 can be coupled to theplate 54. In some embodiments, thepanel 104 can comprise a substantially similar size and shape as the outer perimeter of theplate 54. For example, as shown inFIGS. 14 and 15 , in some embodiments, thepanel 104 can comprise a substantially square or rectangular shape to correspond to the similar shape of the outer perimeter of theplate 54. In some embodiments, thepanel 104 can comprise a substantially single element, and in other embodiments, thepanel 104 can comprise multiple elements coupled together to form thepanel 104. Moreover, in some embodiments, thepanel 104 need not comprise a size and shape substantially similar to theplate 54. - In some embodiments, the
panel 104 can be coupled to theplate 54 via therecess 102. In some embodiments, thepanel 104 can comprise apanel flange 106 that is configured and arranged to engage therecess 102. For example, in some embodiments, after positioning the second set ofillumination devices 58 within therecess 102, at least a portion of thepanel flange 106 can be positioned within therecess 102 to couple thepanel 104 to theplate 54. In some embodiments, thepanel 104 can be snap fit, interference fit, or coupled to theplate 54 via any other previously mentioned coupling techniques. In some embodiments, thepanel 104 can be coupled to and surround the entire outer perimeter of theplate 54, however, in other embodiments, thepanel 104 can be positioned around any lesser proportion of theplate 54. - In some embodiments, at least a portion of the
panel flange 106 can be substantially immediately adjacent to the second set ofillumination devices 58 within therecess 102. In some embodiments, a surface of thepanel flange 106 immediately adjacent to the second set ofillumination devices 58 can comprise a substantially reflective surface. As a result, in some embodiments, at least a portion of the illumination provided by the second set ofillumination devices 58 can be centrally reflected by the reflective surface to improve illumination of theplate 54. - In some embodiments, as shown in
FIGS. 3 , 6, and 7, theplate 54 can include a set ofillumination notches 66. In some embodiments, theillumination notches 66 can be of a generally semi-circular shape, although in other embodiments theillumination notches 66 can be a shape that is generally square, rectangular, elliptical, oval, or any other regular or irregular shape. In some embodiments, theillumination notches 66 can be substantially equidistantly spaced around the circumference of theplate aperture 60, although in other embodiments, theillumination notches 66 can be spaced in any manner desired. In some embodiments, the number of theillumination notches 66 can be the same as the number ofstep members 48. In other embodiments, the numbers ofillumination notches 66 andstep members 48 can be different. In some embodiments, some or all of theillumination notches 66 can include thetextured surface 62, independently of whether the remainder of the walls of theplate aperture 60 includes thetextured surface 62. - In some embodiments, after the
plate 54 has been coupled to thegrille 32, theillumination notches 66 can substantially align with theillumination apertures 56 and the second set ofillumination devices 58. In some embodiments, when the second set ofillumination devices 58 are activated, theillumination notches 66 can aid in dispersing illumination to the remainder of theplate 54 and to the local environment as well. In some embodiments, thetextured surface 62, whether included in theillumination notches 66 or not, can further enhance illumination distribution to theplate 54 and the local environment relative to embodiments which can substantially lack thetextured surface 62. Additionally, in some embodiments, the second set ofillumination devices 58 can be positioned adjacent to a reflective surface so that after activation of the second set ofillumination devices 58, thesecond set 58 can radiate illumination generally toward the reflective surface which can reflect a substantial amount of the illumination toward theplate 54. - In some embodiments, the
plate 54 can include light pipes 68. In some embodiments, the light pipes 68 can be substantially internalized within theplate 54. In other embodiments, the light pipes 68 can be coupled to a surface of theplate 54. In some embodiments, the light pipes 68 can extend from an area adjacent to each of theillumination notches 66 to an area generally adjacent to an outer perimeter of theplate 54. In some embodiments, the light pipes 68 can extend any distance from the area adjacent to each of theillumination notches 66. Thelight pipes 60 can aid in conducting any illumination from the second set ofillumination devices 58 to the outer perimeter of theplate 54 and to the local environment. - Referring to
FIG. 3 , in some embodiments, thegrille 32 can include apilot light 70. Thepilot light 70 can be any of the above-discussed illumination devices. In some embodiments, thepilot light 70 can be configured to radiate illumination when the ventilatingassembly 14 is in a substantially operative state. In some embodiments, the ventilatingassembly 14 can produce so little noise that it can be difficult to substantially audibly perceive it is in the operative state. In some embodiments, when thepilot light 70 is illuminated, an additional signal that the ventilating assembly is operating can be perceived by the user. Thepilot light 70 can aid in potentially preventing unintended overuse of the ventilatingassembly 14. Additionally, in some embodiments, thepilot light 70 can provide substantially green illumination, but in other embodiments, thepilot light 70 can provide any other color of illumination that would be desirable by the user and/or manufacturer. - In some embodiments, at least one of the plate's 54 light pipes 68 can be substantially aligned with the
pilot light 70 so that when thegrille 32 is coupled to theplate 54, the light pipe 68 is substantially adjacent to thepilot light 70. In some embodiments, this light pipe 68 can aid in conducting the pilot light's 70 illumination from thegrille 32 through theplate 54 which can lead to easier visualization by the user. - As illustrated in
FIGS. 1 and 3 , in some embodiments of the invention, thelens 26 can be coupled to thesystem 10. Thelens 26 can aid in diffusing illumination emitted by either thefirst set 18 or thesecond set 58 of illumination devices. In some embodiments, thelens 26 can be coupled to thegrille 32 and/or theplate 54 by any of a number of the above-discussed coupling techniques, including snap-fitting, fasteners, or adhesives. Alternatively, thelens 26 can be integrally formed with either thegrille 32 and/or theplate 54. - Referring to
FIGS. 5 and 7 , in some embodiments of the invention, the ventilatingassembly 14 can include a centrifugal fan orfan wheel 72 connected to amotor plate 74 or other structure within themain housing 12. In some embodiments, any other type of fan other than a centrifugal orfan wheel 72 can be employed, including propeller-type fans. - In some embodiments, the
system 10 can include themotor 28 connected to themotor plate 74 by abracket 76. Themotor 28 can include a motor shaft, which can extend through thebracket 76 and/or themotor plate 74 to produce ventilating airflow. In some embodiments, the ventilatingassembly 14 can be removeably connected within themain housing 14 as a single integral unit. - In some embodiments, when the ventilating
assembly 14 is installed within themain housing 12, thefan 72 can be supported adjacent to an arcuate,upstanding wall 80. Together with a bottom wall of themain housing 12 and themotor plate 74, theupstanding wall 80 can define a scroll housing for generating airflow. In some embodiments, thefan wheel 72 can be positioned relative to theupstanding wall 80 to form a scroll inlet to receive air through theapertures 20, and a scroll outlet to discharge air out of the ventilatingoutlet 22. For example, in some embodiments, a flow of air can flow around theplate 54 and enter themain housing 12 through theaperture 20 defined by thelower flange 92. - In some embodiments, one or more power consuming devices, including, but not limited to the
motor 28, the first and second set ofillumination devices pilot light 70 can be powered by an internal electrical circuit of a building. In some embodiments, one common line from one side of themain housing 12 can provide an inlet for one or more lines of power to enter themain housing 12 and power one or more of the power-consuming devices. - In some embodiments, one or more switches, such as wall switches can be used to activate or deactivate any of the power-consuming devices. In some embodiments, three separate switches can be used to control the ventilating
assembly 14, the first set ofillumination devices 18, and the second set ofillumination devices 58. In some embodiments, one switch can be used to control all three. Further, in some embodiments, as discussed above, the motion-sensing monitor can be used to control any of the ventilatingassembly 14, the first set ofillumination devices 18, and the second set ofillumination devices 58. - Each of these non-limiting examples can stand on its own, or can be combined in any permutation or combination with any one or more of the other examples.
