     TECHNICAL FIELD 
     Embodiments of the present disclosure generally relate to a light fixture configuration module, and in particular to a fixture configuration module that controls a light fixture to produce light within a particular range. 
     BACKGROUND 
     In recent years, a movement has gained traction to replace incandescent light bulbs with light fixtures that employ more efficient lighting technologies as well as to replace relatively efficient fluorescent light fixtures with lighting technologies that produce a more pleasing, natural light. One such technology that shows tremendous promise employs light emitting diodes (LEDs). Compared with incandescent bulbs, LED-based light fixtures are much more efficient at converting electrical energy into light, are longer lasting, and are also capable of producing light that is very natural. Compared with fluorescent lighting, LED-based fixtures are also very efficient, but are capable of producing light that is much more natural and more capable of accurately rendering colors. As a result, light fixtures that employ LED technologies are expected to replace incandescent and fluorescent bulbs in residential, commercial, and industrial applications. 
     Unlike incandescent bulbs that operate by subjecting a filament to a desired current, LED-based light fixtures require electronics to drive one or more LEDs. The electronics generally include a power supply and a special control circuitry to provide uniquely configured signals that are required to drive the one or more LEDs in a desired fashion. The presence of the control circuitry adds a potentially significant level of intelligence to the light fixtures that can be leveraged to employ various types of lighting control.

     Relative terms such as “below” or “above” or “upper” or “lower” or “horizontal” or “vertical” may be used herein to describe a relationship of one element, layer, or region to another element, layer, or region as illustrated in the Figures. It will be understood that these terms and those discussed above are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. 
     The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “includes,” and/or “including” when used herein specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms used herein should be interpreted as having a meaning that is consistent with their meaning in the context of this specification and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
     For clarity in understanding the disclosure below, to the extent that “one of” a conjunctive list of items (e.g., “one of A and B”) is discussed, the present disclosure refers to one (but not both) of the items in the list (e.g., an A or a B, but not both A and B). Such a phrase does not refer to one of each of the list items (e.g., one A and one B), nor does such a phrase refer to only one of a single item in the list (e.g., only one A, or only one B). Similarly, to the extent that “at least one of” a conjunctive list of items is discussed (and similarly for “one or more of” such a list), the present disclosure refers to any item in the list or any combination of the items in the list (e.g., an A only, a B only, or both an A and a B). Such a phrase does not refer to at least one of each of the items in the list (e.g., at least one of A and at least one of B). 
     As will be described in detail below, particular aspects of the present disclosure may be implemented entirely as hardware, entirely as software (including firmware, resident software, micro-code, etc.), or as a combination of hardware and software. For example, embodiments of the present disclosure may take the form of a non-transitory computer readable medium storing software instructions in the form of a computer program that, when executed on a programmable device, configures the programmable device to execute the various methods described below. 
     As will be discussed in greater detail below, various embodiments of the present disclosure are directed to a light fixture, electronics that control the light fixture, a computer readable medium configured with software instructions that (when executed) control the light fixture, and/or methods of controlling the light fixture. Particular embodiments are directed to a fixture configuration module that controls the light fixture to produce light in accordance with particular lighting parameters. Such a fixture configuration module may be removably coupled to the light fixture or may be integrated with the electronics of the light fixture, according to particular embodiments.  FIG. 1  illustrates an example of such a light fixture  10 , according to one or more embodiments of the present disclosure. 
     While the disclosed light fixture  10  illustrated in  FIG. 1  employs an indirect lighting configuration wherein light is initially emitted upward from a light source and then reflected downward, direct lighting configurations may also take advantage of the concepts of the present disclosure. In addition to troffer-type light fixtures, the concepts of the present disclosure may also be employed in recessed lighting configurations, wall mount lighting configurations, outdoor lighting configurations, and the like. In particular, the functionality and control techniques described below may be used to control different types of light fixtures, as well as different groups of the same or different types of light fixtures at the same time. 
     In general, troffer-type light fixtures, such as the light fixture  10 , are designed to mount in a ceiling. In most applications, the troffer-type light fixtures are mounted into a drop ceiling (not shown) of a commercial, educational, or governmental facility. As illustrated in  FIGS. 1-3 , the light fixture  10  includes a square or rectangular outer frame  12 . In the central portion of the light fixture  10  are two rectangular lenses  14 , which are generally transparent, translucent, or opaque. Reflectors  16  extend from the outer frame  12  to the outer edges of the lenses  14 . The lenses  14  effectively extend between the innermost portions of the reflectors  16  to an elongated heatsink  18 , which functions to join the two inside edges of the lenses  14 . 
     Turning now to  FIGS. 2 and 3  in particular, the back side of the heatsink  18  provides a mounting structure for an LED array  20 , which includes one or more rows of individual LEDs mounted on an appropriate substrate. The LEDs are oriented to primarily emit light upwards toward a concave cover  22 . The volume bounded by the cover  22 , the lenses  14 , and the back of the heatsink  18  provides a mixing chamber  24 . As such, light will emanate upwards from the LEDs of the LED array  20  toward the cover  22  and will be reflected downward through the respective lenses  14 , as illustrated in  FIG. 3 . Notably, not all light rays emitted from the LEDs will reflect directly off of the bottom of the cover  22  and back through a particular lens  14  with a single reflection. Many of the light rays will bounce around within the mixing chamber  24  and effectively mix with other light rays, such that a desirably uniform light is emitted through the respective lenses  14 . 
     The type of lenses  14 , the type of LEDs, the shape of the cover  22 , and any coating on the bottom side of the cover  22 , among many other variables, will affect the quantity and quality of light emitted by the light fixture  10 . As will be discussed in greater detail below, the LED array  20  may include LEDs of different colors or color temperatures, wherein the light emitted from the various LEDs mixes together to form a white light having a desired color temperature and quality based on the design parameters for the particular embodiment. 
     As used herein, the term LED may comprise packaged LED chip(s) or unpackaged LED chip(s). LED elements or modules of the same or different types and/or configurations. The LEDs can comprise single or multiple phosphor-converted white and/or color LEDs, and/or bare LED chip(s) mounted separately or together on a single substrate or package that comprises, for example, at least one phosphor-coated LED chip either alone or in combination with at least one color LED chip, such as a green LED, a yellow LED, a red LED, etc. The LED module can comprise phosphor-converted white or color LED chips and/or bare LED chips of the same or different colors mounted directly on a printed circuit board (e.g., chip on board) and/or packaged phosphor-converted white or color LEDs mounted on the printed circuit board, such as a metal core printed circuit board or FR4 board. In some embodiments, the LEDs can be mounted directly to the heat sink or another type of board or substrate. Depending on the embodiment, the lighting device can employ LED arrangements or lighting arrangements using remote phosphor technology as would be understood by one of ordinary skill in the art, and examples of remote phosphor technology are described in U.S. Pat. No. 7,614,759, assigned to the assignee of the present invention and hereby incorporated by reference. 
     In those cases where a soft white illumination with improved color rendering is to be produced, each LED element or module or a plurality of such elements or modules may include one or more blue shifted yellow LEDs and one or more red or red/orange LEDs as described in U.S. Pat. No. 7,213,940, assigned to the assignee of the present invention and hereby incorporated by reference. In some embodiments, each LED element or module or a plurality of such elements or modules may include one or more blue LEDs with a yellow or green phosphor and one or more blue LEDs with a red phosphor. The LEDs may be disposed in different configurations and/or layouts as desired, for example utilizing single or multiple strings of LEDs where each string of LEDs comprise LED chips in series and/or parallel. Different color temperatures and appearances could be produced using other LED combinations of single and/or multiple LED chips packaged into discrete packages and/or directly mounted to a printed circuit board as a chip-on board arrangement. In one embodiment, the light source comprises any LED, for example, an XP-Q LED incorporating TrueWhite® LED technology or as disclosed in U.S. patent application Ser. No. 13/649,067, filed Oct. 10, 2012, entitled “LED Package with Multiple Element Light Source and Encapsulant Having Planar Surfaces” by Lowes et al., the disclosure of which is hereby incorporated by reference herein, as developed and manufactured by Cree, Inc., the assignee of the present application. If desirable, other LED arrangements are possible. In some embodiments, a string, a group of LEDs or individual LEDs can comprise different lighting characteristics and by independently controlling a string, a group of LEDs or individual LEDs, characteristics of the overall light out output of the device can be controlled. 
     In some embodiments, each LED element or module may comprise one or more LEDs disposed within a coupling cavity with an air gap being disposed between the LED element or module and a light input surface. In any of the embodiments disclosed herein each of the LED element(s) or module(s) can have different or the same light distribution, although each may have a directional emission distribution (e.g., a side emitting distribution), as necessary or desirable. More generally, any Lambertian, symmetric, wide angle, preferential-sided or asymmetric beam pattern LED element(s) or module(s) may be used as the light source. For example, the LEDs in the fixtures may include LED components having multiple color temperatures. 
     By providing a lighting fixture that includes a string, a group of LEDs or individual LEDs can comprise different lighting characteristics and by independently controlling a string, a group of LEDs or individual LEDs, characteristics of the overall light out output of the device can be controlled. Traditionally, a single fixture may include multiple stock keeping unit (SKU) identifiers. For example, a particular fixture style may come in a 4000 lumen output model or 5000 lumen output model. For each of those lumen outputs, the fixture may come in a 3000 k correlated color temperature (CCT), 3500 k CCT, 4000 k CCT, or 5000 k CCT. Each of those configurations would have a its own SKU. By using an LED configuration as described above, a single LED fixture having a single SKU can be stocked, and the fixture configuration module described below allows for selecting any of the above listed lumen and/or CCT configurations. 
     As is apparent from  FIGS. 2 and 3 , the elongated fins of the heatsink  18  may be visible from the bottom of the light fixture  10 . Placing the LEDs of the LED array  20  in thermal contact along the upper side of the heatsink  18  allows heat generated by the LEDs to be effectively transferred to the elongated fins on the bottom side of the heatsink  18  for dissipation within the room in which the light fixture  10  is mounted. Again, the particular configuration of the light fixture  10  illustrated in  FIGS. 1-3  is merely one of the virtually limitless configurations for light fixtures  10  in which the concepts of the present disclosure are applicable. 
     With continued reference to  FIGS. 2 and 3 , an electronics housing  26  is shown mounted at one end of the light fixture  10 , and is used to house all or a portion of the electronics used to power and control the LED array  20 . These electronics are coupled to the LED array  20  through appropriate cabling  28 . With reference to  FIG. 4 , the electronics provided in the electronics housing  26  may be divided into a driver module  30  and a fixture configuration module  32 . 
     The driver module  30  is coupled to the LED array  20  through the cabling  28  and directly drives the LEDs of the LED array  20  based on control signaling provided by the fixture configuration module  32 . The driver module  30  may be provided on a single, integrated module, may be divided into two or more sub-modules, and/or may be integrated with the fixture configuration module  32 , according to various embodiments. 
     The fixture configuration module  32 , in some embodiments, is a communications module that acts as an intelligent communication interface facilitating communications between the driver module  30  and other light fixtures  10 , a remote control system (not shown), and/or a portable handheld commissioning tool  36 , which may also be configured to communicate with a remote control system in a wired or wireless fashion. The fixture configuration module  32  may additionally or alternatively be a control module that acts as a manual configuration interface facilitating local control of the driver module  30  by a manual user and/or the portable handheld commissioning tool  36  within a limited range. 
     According to particular embodiments, the fixture configuration module  32  may enforce operating limits on the light fixture  10 . That is, the light fixture  10  may support a particular range of values with respect to a given lighting parameter (such as color temperature or brightness), and the fixture configuration module  32  may control the light fixture  10  to produce light in accordance with a range that is a subset of those supported values. For example, the fixture configuration module  32  may limit the light fixture  32  to producing light at color temperatures between 3000K and 4200K, even though the light fixture  10  supports producing light at color temperatures anywhere between 2700K and 5500K. Additionally or alternatively, the fixture configuration module  32  may limit the light fixture  32  to producing light at a lumen level between 2800 lumens and 3100 lumens, even though the light fixture  10  supports producing light at lumen levels anywhere between 1000 lumens and 5000 lumens. One or more of these ranges and/or lighting parameter values may be preprogrammed, field programmable, user-configurable, and/or remotely controllable according to various embodiments, as will be described in greater detail below. 
     In the embodiment of  FIG. 4 , the fixture configuration module  32  is implemented on a separate printed circuit board (PCB) than the driver module  30 . The respective PCBs of the driver module  30  and the fixture configuration module  32  may be configured to allow the connector of the fixture configuration module  32  to plug into the connector of the driver module  30 , wherein the fixture configuration module  32  is mechanically mounted, or affixed, to the driver module  30  once the connector of the fixture configuration module  32  is plugged into the mating connector of the driver module  30 . 
     Other embodiments include arrangements in which the fixture configuration module  32 , driver module  30 , and/or other electronics of the light fixture  10  are integrated. For example, the fixture configuration module  32  and driver module  30  may be implemented on the same PCB and/or use shared components. In particular, the fixture configuration module  32  and driver module  30  may share one or more microprocessors (not shown in  FIG. 4 ) in order to perform aspects of their respective functions. 
     In other embodiments, a cable may be used to connect the respective connectors of the driver module  30  and the fixture configuration module  32 , other attachment mechanisms may be used to physically couple the fixture configuration module  32  to the driver module  30 , or the driver module  30  and the fixture configuration module  32  may be separately affixed to the inside of the electronics housing  26 . In such embodiments, the interior of the electronics housing  26  is sized appropriately to accommodate both the driver module  30  and the fixture configuration module  32 . In many instances, the electronics housing  26  provides a plenum rated enclosure for both the driver module  30  and the fixture configuration module  32 . 
     With the embodiment of  FIG. 4 , adding or replacing the fixture configuration module  32  requires gaining access to the interior of the electronics housing  26 . If this is undesirable, the driver module  30  may be provided alone in the electronics housing  26 . The fixture configuration module  32  may be mounted outside of the electronics housing  26  in an exposed fashion or within a supplemental housing  34 , which may be directly or indirectly coupled to the outside of the electronics housing  26 , as shown in  FIG. 5 . The supplemental housing  34  may be bolted to the electronics housing  26 . The supplemental housing  34  may alternatively be connected to the electronics housing using snap-fit or hook-and-snap mechanisms. The supplemental housing  34 , alone or when coupled to the exterior surface of the electronics housing  26 , may provide a plenum rated enclosure. 
     In embodiments where the electronics housing  26  and the supplemental housing  34  will be mounted within a plenum rated enclosure, the supplemental housing  34  may not need to be plenum rated. Further, the fixture configuration module  32  may be directly mounted to the exterior of the electronics housing  26  without any need for a supplemental housing  34 , depending on the nature of the electronics provided in the fixture configuration module  32 , how and where the light fixture  10  will be mounted, and the like. The latter embodiment wherein the fixture configuration module  32  is mounted outside of the electronics housing  26  may prove beneficial when the fixture configuration module  32  facilitates wireless communications with the other light fixtures  10 , the remote control system, or other network or auxiliary device. In essence, the driver module  30  may be provided in the plenum rated electronics housing  26 , which may not be conducive to wireless communications. The fixture configuration module  32  may be mounted outside of the electronics housing  26  by itself or within the supplemental housing  34  that is more conducive to wireless communications. A cable may be provided between the driver module  30  and the fixture configuration module  32  according to a defined communication interface. As an alternative, which is described in detail further below, the driver module  30  may be equipped with a first connector that is accessible through the wall of the electronics housing  26 . The fixture configuration module  32  may have a second connector, which mates with the first connector to facilitate communications between the driver module  30  and the fixture configuration module  32 . 
     The embodiments that employ mounting the fixture configuration module  32  outside of the electronics housing  26  may be somewhat less cost effective, but provide significant flexibility in allowing the fixture configuration module  32  or other auxiliary devices to be added to the light fixture  10 , serviced, or replaced. The supplemental housing  34  for the fixture configuration module  32  may be made of a plenum rated plastic or metal, and may be configured to readily mount to the electronics housing  26  through snaps, screws, bolts, or the like, as well as receive the fixture configuration module  32 . The fixture configuration module  32  may be mounted to the inside of the supplemental housing  34  through snap-fits, screws, twistlocks, and the like. The cabling and connectors used for connecting the fixture configuration module  32  to the driver module  30  may take any available form, such as with standard category 5 (cat 5) cable having RJ45 connectors, edge card connectors, blind mate connector pairs, terminal blocks and individual wires, and the like. Having an externally mounted fixture configuration module  32  relative to the electronics housing  26  that includes the driver module  30  allows for easy field installation of different types of fixture configuration modules  32 , communications modules, or modules with other functionality for a given driver module  30 . 
     As illustrated in  FIG. 5 , the fixture configuration module  32  is mounted within the supplemental housing  34 . In this particular example, the supplemental housing  34  is attached to the electronics housing  26  with bolts. As such, the fixture configuration module  32  is readily attached and removed via the illustrated bolts. In such embodiments, a screwdriver, ratchet, or wrench, depending on the type of head for the bolts, may be required to detach or remove the fixture configuration module  32  via the supplemental housing  34 . 
     As an alternative, the fixture configuration module  32  may be configured as illustrated in  FIGS. 6A and 6B . In this configuration, the fixture configuration module  32  may be attached to the electronics housing  26  of the light fixture  10  in a secure fashion and may subsequently be released from the electronics housing  26  without the need for bolts. In particular, the fixture configuration module  32  may have a two-part module housing  38 , which is formed from a front housing section  40  and a rear housing section  42 . As will be described further below, the electronics for the fixture configuration module  32  are housed within the module housing  38 . 
     The rear of the module housing  38  illustrated in the example of  FIG. 6B  includes two snap-lock connectors  44  that are biased to opposing sides of the module housing  38 . Each snap-lock connector  44  includes a fixture locking member  46 , a spring member  48 , a button member  50 , and two housing locking members  52 . Each of the fixture locking member  46 , the spring member  48 , the button member  50 , and the housing locking members  52  essentially extend from a central body portion  54  in the illustrated embodiment. 
     The rear housing section  42  is provided with two pairs of elongated channel guides  56 . Each pair of the channel guides  56  are biased toward the outside of the rear housing section  42 , and form a channel, which will receive the snap-lock connector  44 . Once the snap-lock connectors  44  are extended far enough into the channel formed by the pair of channel guides  56 , barbs on the housing locking members  52  will engage the inside surfaces of the channel guides  56  and effectively lock the snap-lock connectors  44  in place in the channel formed by the channel guides  56 . 
     Also located on the outside surface of the rear housing section  42  is a flame barrier  58 , which is configured to surround an opening  580  that extends into the module housing  38 . A connector  60 , which provides an electrical interface to the electronics of the fixture configuration module  32 , extends into or through the opening  580 . In the illustrated embodiment, the flame barrier  58  is a continuous wall that surrounds the opening  580  and extends from the exterior surface of the rear housing section  42 . The flame barrier  58  is square, but may form a perimeter of any desired shape. The flame barrier  58  is configured to mate flush against the electronics housing  26  of the light fixture  10  or a mating component provided thereon. The channel guides  56  may extend to and form part of a connector rim  62 , which effectively provides an aesthetically pleasing recess in which the button member  50  of the snap-lock connector  44  may reside. 
     As shown in  FIG. 7 , the fixture configuration module  32  may further comprise one or more mechanical switches  90 , each of which may be positioned to one of a plurality of switch positions. Positioning a mechanical switch  90  to one of the switch positions may designate one of a plurality of ranges to which a corresponding lighting parameter of the light fixture  10  will be limited by the fixture configuration module  32 . 
     In the particular example illustrated in  FIG. 7 , the fixture configuration module comprises mechanical switches  90  in the form of rotary dials, each of which may be rotated through a plurality of different positions, each position corresponding to a different range. Other embodiments may additionally or alternatively include one or more other types of mechanical switches  90 , including (but not limited to) pushbutton switches, rocker switches, tactile switches, dipswitches, proximity switches, slide switches, toggle switches, and/or snap switches. 
     The particular mechanical switches  90  illustrated in  FIG. 7  are configured to designate ranges for different respective lighting parameters of the light fixture  10 , namely, CCT level and lumen level. Other embodiments of the fixture configuration module  32  include mechanical switches  90  used for other purposes. For example, according to embodiments, a mechanical switch  90  may be used to locally set a value of a lighting parameter of the light fixture  10 . In some embodiments, the locally set value may be a maximum or minimum value for the light fixture  10  (e.g., a maximum color temperature of 5000K, a minimum brightness of 1000 lumens). In other embodiments, the locally set value may be a value at which the fixture configuration module  32  controls the light fixture  10  to produce light (e.g., an actual color temperature of light desired from the light fixture  10 ). 
     The lighting parameter to which each switch corresponds may be formed and/or printed on the front housing section  40 , as shown in  FIG. 7 . Each of the mechanical switches  90  in the example of  FIG. 7  is set to a position corresponding to a range programmed via near-field communication (NFC), as depicted by the NFC label on the exposed face of each dial. In some other embodiments, the fixture configuration module  32  interprets the setting of any of the mechanical switches  90  to the NFC position as an instruction to use whatever NFC programmed ranges have been stored for each of the lighting parameters associated with the mechanical switches  90 . For example, in response to a first mechanical switch being set to the NFC position, and a second mechanical switch being set to a non-NFC position, the fixture configuration module  32  may be configured to apply NFC programmed ranges to the lighting parameters associated with both of the mechanical switches  90 . Alternatively, in some embodiments, only one of a plurality of mechanical switches  90  has an NFC position, and the fixture configuration module  32  is configured to apply whichever programmed ranges as the fixture configuration module  32  may have stored in association with the NFC setting in response to the NFC position being used. 
     Other embodiments of the fixture configuration module  32  additionally or alternatively include a mechanical reset button accessed through a hole  92  in the front section housing  40 . The hole  92  may be sized such that actuation of the mechanical reset button may require insertion of a thin tool (e.g., paperclip, thumbtack, toothpick) as a safety measure against accidentally resetting the fixture configuration module  32 . In particular, the mechanical reset button may be configured to produce a reset signal upon actuation. This reset signal may cause the fixture configuration module  32  to override one or more of the ranges used by the fixture configuration module  32  to limit operation of the light fixture  10 , as will be discussed further below. Other embodiments may include a reset button that is mounted to the front housing section  40  such that a user may actuate the reset button without the use of a tool. 
     Other embodiments may have additional or alternative input mechanisms, any or all of which may be mechanical and/or electronic in nature. Further details concerning the mechanical inputs and electronics of the fixture configuration module  32  according to various embodiments will be discussed in greater detail below. 
     Turning now to  FIGS. 8A and 8B , front and back exploded perspective views of an exemplary snap-lock connector  44  are shown. As illustrated, the front housing section  40  and the rear housing section  42  mate together to enclose a printed circuit board (PCB)  64 , which includes the requisite electronics of the fixture configuration module  32 . On the side of the PCB  64  where most of the electronic components are mounted, the aforementioned reset button  66  may be mounted. On the opposite side of the PCB  64 , the connector  60  is mounted in a location that allows it to extend into and partially through the opening  580 . 
     The front housing section  40  and the rear housing section  42  may be formed from a variety of materials, such as fiberglass, thermoplastics, metal, and the like. In this instance, the front housing section  40  is formed from a thermoplastic. As illustrated in  FIG. 8A , a logo may be formed or printed on the exterior surface of the front housing section  40 . 
     Also illustrated in  FIGS. 8A and 8B  are the snap-lock connectors  44  prior to being inserted into the respective channels formed by the channel guides  56 . As each snap-lock connector  44  is inserted into the channel formed by the pair of channel guides  56 , barbs of the housing locking members  52  contact the opening of the channel and are deflected inward toward one another. Each snap-lock connector  44  is pushed into and through the corresponding channel until the rear of the barbs pass the back of the channel guides  56 . Once the rear of the barbs pass the rear of the channel guides  56 , the housing locking members  52  will spring outward toward their normal resting state, thus locking the snap-lock connector  44  in place against the back of the rear housing section  42 . To remove the snap-lock connector  44 , the housing locking members  52  need to be deflected inward, while the snap-lock connector  44  is pulled back out through the channel formed by the channel guides  56 . 
     When the snap-lock connectors  44  are in place, the free end of the spring member  48  rests against a proximate side of the flame barrier  58 . When the snap-lock connector  44  is in place, the spring member  48  may be slightly compressed or not compressed at all. As such, the spring member  48  effectively biases the snap-lock connector  44  in an outward direction through the channels formed by the respective pairs of channel guides  56 . In essence, pressing and releasing the button member  50  of the snap-lock connector  44  moves the fixture locking member  46  inward and then outward. If a user applies pressure inward on the button member  50  and thus presses the snap-lock connector  44  inward, the spring member  48  will further compress. When the pressure is released, the spring member  48  will push the snap-lock connector  44  back into its normal resting position. As will be described below, pressing both of the snap-lock connectors  44  inward via the button members  50  will effectively disengage the communications module  32  from the electronics housing  26  of the light fixture  10 . 
       FIG. 9A  illustrates the fixture configuration module  32  prior to being attached to or just after being released from the electronics housing  26  of the light fixture  10 . As illustrated, one surface of the electronics housing  26  of the light fixture  10  includes two locking interfaces  72 , which are essentially openings into the electronics housing  26  of the light fixture  10 . The openings for the locking interfaces  72  correspond in size and location to the fixture locking members  46 . Further, a connector  70  that leads to or is coupled to a PCB of the electronics for the driver module  30  is provided between the openings of the locking interfaces  72 . In this example, the connector  60  of the fixture configuration module  32  is a male connector that is configured to be received by the female connector  70 , which is mounted on the electronics housing  26  of the light fixture  10 . 
     As the fixture configuration module  32  is snapped into place on the electronics housing  26  of the light fixture  10 , as illustrated in  FIG. 9B , the male connector  60  of the fixture configuration module  32  will engage the female connector  70  of the driver module  30  as the fixture locking members  46  engage the respective openings of the locking interfaces  72 . In particular, when the barbs of the fixture locking members  46  engage the respective openings of the locking interfaces  72 , the fixture locking members  46  will deflect inward until the rear portion of the barbs pass the rear surface of the wall for the electronics housing  26 . At this point, the fixture locking members  46  will move outward, such that the rear portions of the barbs engage the rear surface of the wall of the electronics housing  26 . At this point, the fixture configuration module  32  is snapped into place to the electronics housing  26  of the lighting fixture  10 , and the connectors  60  and  70  of the fixture configuration module  32  and the driver module  30  are fully engaged. 
     The fixture configuration module  32  may be readily released from the electronics housing  26  by pressing both of the snap-lock connectors  44  inward via the button members  50  and then pulling the fixture configuration module  32  away from the electronics housing  26  of the light fixture  10 . Pressing the snap-lock connectors  44  inward effectively moves the barbs inward and into the respective openings of the locking interfaces  72 , such that they can readily slide out of the respective openings of the locking interfaces  72 . Thus, the fixture configuration module  32  may be readily attached and removed from the electronics housing  26  in a fluid and ergonomic fashion, without the need for additional tools. In the illustrated embodiment, the flame barrier  58  rests securely against the exterior surface of the electronics housing  26  of the lighting fixture  10  and acts to seal off the connector interface for the connectors  60  and  70 . Thus, the flame barrier  58  may provide a plenum flame barrier for the connector interface and the electronics housed within the fixture configuration module  32 . 
     According to various embodiments, modules of any type of capability may be configured in the same manner as one or more embodiments of the fixture configuration module  32  described herein. Thus, any number of modules that provide one or more special functions may be housed in a similar housing and connected to the driver module  30 . According to such embodiments, the functionality provided by the electronics within the housing  34  may vary in order to provide the desired functionality. For example, such modules may be used to provide one or more functions, such as wireless communications, occupancy sensing, ambient light sensing, temperature sensing, emergency lighting operation, and the like. 
       FIG. 10  illustrates example electronics  100  of the fixture configuration module  32 . The electronics  100  comprises processing circuitry  110  and interface circuitry  130 . The processing circuitry  110  is communicatively coupled to the interface circuitry  130 , e.g., via one or more buses. The processing circuitry  110  may comprise one or more microprocessors, microcontrollers, hardware circuits, discrete logic circuits, hardware registers, digital signal processors (DSPs), field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), or a combination thereof. For example, the processing circuitry  110  may be programmable hardware capable of executing software instructions  160  stored, e.g., as a machine-readable computer program in memory circuitry  120  of the processing circuitry  110 . Such memory circuitry  120  may comprise any non-transitory machine-readable media known in the art or that may be developed, whether volatile or non-volatile, including but not limited to solid state media (e.g., SRAM, DRAM, DDRAM, ROM, PROM, EPROM, flash memory, solid state drive, etc.), removable storage devices (e.g., Secure Digital (SD) card, miniSD card, microSD card, memory stick, thumb-drive, USB flash drive, ROM cartridge, Universal Media Disc), fixed drive (e.g., magnetic hard disk drive), or the like, wholly or in any combination. 
     The interface circuitry  130  may be a controller hub configured to control the input and output (I/O) data paths of the electronics  100 . Such I/O data paths may include data paths for wirelessly exchanging signals with local devices and/or over a communications network. Such I/O data paths may additionally or alternatively include one or more buses (e.g., an I2C bus) for exchanging signaling with a light fixture  10 . Such data paths may additionally or alternatively include data paths for exchanging signals with mechanical switches  90  and/or buttons for receiving input from a user. 
     In particular, the interface circuitry  130  may comprise one or more transceivers, each of which may be configured to send and receive communication signals over a particular radio access technology. For example, the interface circuitry may comprise a far-field radio transceiver for communicating with one or more devices on a wireless local area network (WLAN) and/or an NFC transceiver for communicating with a nearby device (e.g., the commissioning tool  36 ) via NFC signaling. Other embodiments additionally or alternatively include one or more other forms of transceivers configured to send and receive communication signals over one or more of a wireless medium, wired medium, electrical medium, electromagnetic medium, and/or optical medium. Examples of such transceivers include (but are not limited to) BLUETOOTH, ZIGBEE, optical, and/or acoustic transceivers. 
     The interface circuitry  130  may also comprise one or more mechanical switches  90 , buttons, graphics adapters, display ports, video buses, touchscreens, graphical processing units (GPUs), Liquid Crystal Displays (LCDs), and/or LED displays, for presenting visual information to a user. The interface circuitry  130  may also comprise one or more pointing devices (e.g., a mouse, stylus, touchpad, trackball, pointing stick, joystick), touchscreens, microphones for speech input, optical sensors for optical recognition of gestures, and/or keyboards for text entry. 
     The interface circuitry  130  may be implemented as a unitary physical component, or as a plurality of physical components that are contiguously or separately arranged, any of which may be communicatively coupled to any other, may communicate with any other via the processing circuitry  110 , or may be independently coupled to the processing circuitry  110  without the ability to communicate with one or more other components, according to particular embodiments. For example, the interface circuitry  130  may comprise output circuitry  140  (e.g., an I2C bus configured to exchange signals with the light fixture  10 ) and input circuitry  150  (e.g., receiver circuitry configured to receive communication signals over WLAN and/or NFC signaling). Similarly, the output circuitry  540  may comprise a WLAN transmitter, whereas the input circuitry  550  may comprise one or more mechanical switches  90 . Other examples, permutations, and arrangements of the above and their equivalents are included according to various aspects of the present disclosure. 
     Other embodiments of the electronics  100  of the fixture configuration module  32  may be configured according to the example illustrated in  FIG. 11 . As shown, the electronics  100  are configured to exchange signaling with a light fixture  10 , and may additionally send and/or receive signaling from a commissioning tool  36 , one or more users  295 , and/or a remote device  295 , as will be discussed in further detail below. 
     The electronics  100  in the example of  FIG. 11  comprise range control circuitry  210  and fixture control circuitry  220  communicatively coupled to the range control circuitry  210 . The range control circuitry  210  is configured to store a range of a lighting parameter. The range identifies at least a subset of values of the lighting parameter supported by a light fixture  10  to produce light. The fixture control circuitry  220  is configured to control the light fixture  10  to produce the light in accordance with the range stored by the range control circuitry  210 . 
     In some embodiments, the range control circuitry  210  comprises a mechanical switch  90  configured to designate such a range from a plurality of different ranges by positioning the mechanical switch  90  to one of a plurality of respective switch positions. For example, the lighting parameter to which the range pertains may be color temperature, and a user  295  may position the mechanical switch  90  to a first position to designate a “cool white” range of, e.g., 3100K to 4500K, whereas positioning the mechanical switch  90  to a second position may designate a “warm white” range of, e.g., 2000K to 3000K. Other ranges, including ranges that may overlap, may be designated according to other embodiments and may be based on the particular lighting parameter to be limited using the range control circuitry  210 . Other embodiments may further comprise a further mechanical switch  90  configured to designate another range for a different lighting parameter of the light fixture, such as brightness, as mentioned above. 
     In some embodiments, the range may be programmed in the range control circuitry  210  by the commissioning tool  36 . In particular, the range control circuitry  210  may include a transceiver with which to exchange signaling with the commissioning tool  36  in order to receive the range. In the particular example illustrated in  FIG. 7 , the range control circuitry  210  comprises NFC circuitry  230  configured to program the range control circuitry  210  with a range received via NFC signaling. In some embodiments, to program the range control circuitry  210  with the range received via the NFC signaling, the NFC circuitry  230  is communicatively coupled to non-volatile memory  240 , and is further configured to store the range received via the NFC signaling in the non-volatile memory  240 . In particular, the NFC circuitry  230  may store the range received via the NFC signaling in the non-volatile memory  240  while powered by magnetic induction produced by the NFC signaling. In at least some embodiments, this permits the range to be programmed in the range control circuitry  210  regardless of whether the fixture configuration module  32  is coupled to or decoupled from the light fixture  10 . Indeed, the ability to program the fixture configuration module  32  while decoupled from the light fixture  10  may be advantageous for customizing the fixture configuration module  32  during the manufacturing, packaging, and/or shipping process. For example, according to some such embodiments, the fixture configuration may be wirelessly programmed via NFC signaling before being shipped to a customer site where the light fixture  10  to be controlled is already installed. 
     According to particular embodiments, the fixture control circuitry  220  may be configured to transfer a range from the range control circuitry  210  to the light fixture  10 , such that the light fixture  10  may enforce the range with respect to a particular lighting parameter regardless of whether or not the fixture configuration module  32  is subsequently decoupled from the light fixture  10 . This may, for example, enable a user  295  to briefly couple the same fixture configuration module  32  to each of a plurality of light fixtures  10  in order to limit the range of operation of each. According to other embodiments, the fixture control module may refrain from transferring the range to the light fixture  10 , such that the light fixture  10  is no longer limited to a range stored by the range control circuitry  210  once the fixture configuration module  32  is decoupled. 
     In at least some embodiments in which the range control circuitry  210  comprises a mechanical switch  90 , the range received via NFC signaling may be designated by positioning the mechanical switch  90  to a given position. Further, in some such embodiments, positioning the mechanical switch  90  in one or more other positions may designate other respective ranges not programmed by the NFC circuitry  230 . Thus, a user  295  may, e.g., use the mechanical switch  90  to set the range to the range programmed via NFC signaling or to a predefined range (e.g., programmed in a read only memory (ROM) or other form of non-volatile memory  240 ), as desired. 
     As discussed above, the electronics  100  may, in some embodiments, comprise a connector  60  communicatively coupled to the fixture control circuitry and configured to removably couple with a corresponding connector  70  of the light fixture  10 . In some embodiments, the connector  60  of the fixture configuration module  32  transfers electrical power from the light fixture  10  to the fixture control circuitry  220  while they are coupled via the connector  60 . The connector  60  may additionally or alternatively transfer control signaling between the fixture control circuitry  220  and the light fixture  10 . 
     In some embodiments, the electronics  100  further comprise user interface circuitry  270  that is communicatively coupled to the fixture control circuitry  220 , independently of the range control circuitry  210 . For example, the range control circuitry  210  and user interface circuitry may comprise respective communication circuitry (e.g., NFC circuitry  210  and radio circuitry  280 ), each of which is separately and distinctly connected to the fixture control circuitry  220  (e.g., via separate respective buses). 
     According to embodiments, the user interface circuitry  270  is configured to receive one or more values of the lighting parameter (e.g., via one or more of the input mechanisms described above). In particular, the user interface circuitry  270  may comprise radio circuitry  280 , e.g., to permit remote management of the light fixture  10  by a remote device  290  (such as a workstation, laptop, or server connected by direct wireless connection or via a network to the fixture configuration module  32 ). In such embodiments, the fixture control circuitry  220  may be configured to control the light fixture to produce the light at such values of the lighting parameter received by the user interface circuitry  270  that are within the range stored by the range control circuitry  210  (e.g., and reject or ignore such values of the lighting parameter received by the user interface circuitry  270  that are not within such range, according to some embodiments). 
     In some embodiments, the remote management features discussed above may require a separate software license in order to be enabled in the user interface circuitry  270 . For example, the radio circuitry  280  may be configured to receive a software license from the remote device  290 , and in response, enable a command interface through which the values of the lighting parameter may be received. According to some such embodiments, the absence, expiration, invalidation, and/or cancellation of the software license may disable the remote management features. Nonetheless, the range control circuitry  210  and fixture control circuitry  220  may continue to operate as previously described. 
     In some embodiments, the electronics  100  may further comprise a mechanical reset button  250  that is communicatively coupled to the range control circuitry  210  and is configured to produce a reset signal. In such embodiments, the range control circuitry  210  may be configured to override the range of the lighting parameter stored by the range control circuitry  210  with a default range (e.g., a factory default range) responsive to receiving the reset signal. 
     It should be noted that any or all of the electronics  100  described above may, in particular embodiments, be electronically integrated with each other and/or may be electronically integrated with some or all further electronics of the light fixture, e.g., on one or more PCBs. According to particular embodiments circuitry of the driver module  30  and the fixture control circuitry  220  are electronically integrated. 
     In view of the above, particular embodiments of the present disclosure include various methods of controlling a light fixture  10  implemented by a fixture configuration module  32 . An example of such a method  400  is illustrated in  FIG. 12 . The method  400  comprises storing a range of a lighting parameter (block  410 ). The range identifies at least a subset of values of the lighting parameter supported by the light fixture  10  to produce light. The method  400  further comprises controlling the light fixture  10  to produce the light in accordance with the stored range (block  420 ). 
     Another example of a method  300  implemented by a fixture configuration module  32  and consistent with various embodiments described herein is illustrated in  FIG. 13 . The method  300  begins (block  305 ), according to this example, with the fixture configuration module  32  not yet coupled to the light fixture  10 . The method  300  comprises programming the fixture configuration module  32  with a range received via near-field communication (NFC) signaling (block  310 ). The range identifies at least a subset of values of a lighting parameter supported by the light fixture  10  to produce light. 
     The fixture configuration module  32  is not coupled to the light fixture  10 , and thus not receiving electrical power from the light fixture  10  via its connector  60 . Nonetheless, the fixture configuration module  32  stores the range received via the NFC signaling in a non-volatile memory  240  of the fixture configuration module  32  while powered by magnetic induction produced by the NFC signaling (block  315 ). 
     In this example, the fixture configuration module  32  has a mechanical switch  90  (e.g., a rotary dial) corresponding to the lighting parameter, and may be positioned to one of a plurality of switch positions. One of said switch positions corresponds to the range programmed into the fixture configuration module  32  and received via the NFC signaling. Another of said switch positions corresponds to a different range that is preprogrammed in non-volatile memory  240  and is not received by the NFC circuitry. For example, this different range may be programmed during manufacturing using an EEPROM programming device (or other device). According to this example, the preprogrammed range and the range received via NFC signaling are stored in respective locations of the non-volatile memory  240 , and the mechanical switch  90  designates which location in that non-volatile memory  240  (and correspondingly, which range) is to be used for limiting operation of the light fixture  10  (block  320 ). In particular, the fixture configuration module  32  designates one of these ranges from the plurality of different ranges responsive to a user  295  positioning the mechanical switch  90  to one of the switch positions. 
     In this example, the fixture configuration module  32  has a further mechanical switch  90  corresponding to a different lighting parameter. Accordingly, the fixture configuration module  32  designates a range of the different lighting parameter using this further mechanical switch  90  (block  325 ). In particular, the mechanical switch and the further mechanical switch  90  may designate a color temperature range of the light fixture  10  and a brightness range of the light fixture  10 , respectively. 
     The fixture configuration module  32  is then removably coupled, via a connector  60  of the fixture configuration module  32 , with a corresponding connector  70  of the light fixture  10 , and receives electrical power from the light fixture  10  in response (block  330 ). Under the electrical power of the light fixture  10 , the fixture configuration module  32  receives a software license (e.g., wirelessly from a remote device  290 ) and enables remote management of the light fixture  10  in response (block  335 ). 
     Having enabled remote management, the fixture configuration module  32  receives one or more values of the lighting parameter (e.g., through radio communication with the remote device  290 ) (block  340 ). The fixture configuration module  32  controls the light fixture  10  to produce light at such values of the lighting parameter that are received and are within the corresponding designated range (block  345 ). 
     The fixture configuration module  32  also has a mechanical reset button  250 . If the reset button  250  is pressed (block  350 , yes), the fixture configuration module  32  overrides the range of the lighting parameter received via NFC signaling and stored in the non-volatile memory  240  with a default range in response (block  355 ). Otherwise (block  350 , no), the range received via NFC is not overridden. 
     If the fixture configuration module  32  is not decoupled from the light fixture  10  (block  360 , no), the fixture configuration module  32  will continue to receive further lighting parameter values (block  340 ) and controlling the light fixture according to the designated ranges (block  345 ), until the fixture configuration module  32  is either reset (block  350 , yes) and/or decoupled (block  360 , yes). Once the fixture configuration module  32  is decoupled (block  360 , yes), the method  300  ends.
