Title: Light redirecting flange in luminaires

Description:
TECHNICAL FIELD 
     Embodiments of the present disclosure relate generally to luminaires, and more particularly a light redirecting flange in luminaires. 
     BACKGROUND 
     Luminaires often have a lens to diffuse light coming out of the luminaires. For aesthetics reasons, the lens is typically illuminated evenly across the surface of the luminaires. However, in some instances, there are features in a housing and/or a door assembly positioned behind the lens of a luminaire that create dark portions or other unpleasing aesthetics in the lens of the luminaire. In order to reduce or remove the dark portions behind the lens of the luminaire, light needs to be redirected to create a more even illumination across the lens surface. 
     SUMMARY 
     In one aspect, the present disclosure can relate to a door frame assembly of a luminaire. The door frame assembly includes a first side rail and a second side rail that is opposite to the first side rail. Each of the first side rail and the second side rail includes a first lateral edge, a second lateral edge opposite to the first lateral edge, and longitudinal edges that extend between the first lateral edge and the second lateral edge. Further, the door frame assembly includes an end plate. The end plate includes a bottom edge that extends from the first side rail to the second side rail, and a top edge that is opposite to the bottom edge. The end plate extends from the bottom edge to the top edge. Furthermore, the door frame assembly includes a light redirecting flange comprising a portion of the end plate that diverges away from a remainder portion of the end plate at an angle to the remainder portion of the end plate. 
     In another aspect, the present disclosure can generally relate to luminaire that includes a housing, at least one circuit board coupled to the housing that includes at least one light emitting diode (LED) disposed thereon, and a door frame assembly coupled to the housing. The door frame assembly includes a first side rail and a second side rail that is opposite to the first side rail. Further, the door frame assembly includes an end plate extending from a portion of the first side rail to a corresponding portion of the second side rail and having a top edge and a bottom edge opposite to the top edge. Furthermore, the door frame assembly includes a light redirecting flange that is coupled to the end plate adjacent a notch in the end plate. The light redirecting flange may diverge away from the end plate at an angle to the end plate such that light from the at least one LED that exits the luminaire through the notch is redirected towards the lens of the luminaire. 
     In yet another aspect, the present disclosure can generally relate to a light redirecting flange. The light redirecting flange includes an inward facing surface, an outward facing surface that is opposite to the inward facing surface, a first edge and a second edge that is opposite to the first edge, and a first side edge and a second side edge opposite to the first side edge. The first side edge and the second side edge may extend between the first edge and the second edge. One of the first edge and the second edge of the light redirecting flange may be coupled to an end plate of a luminaire&#39;s door frame assembly adjacent a notch in the end plate. Further, the light redirecting flange may be positioned at an angle to the end plate to redirect light from an LED that exits the notch towards a lens of a luminaire. 
     These and other aspects, objects, features, and embodiments will be apparent from the following description and the appended claims.

Additionally, certain dimensions may be exaggerated to help visually convey such principles. 
     DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS 
     Disclosed are example embodiments of a light redirecting flange in luminaires. Before discussing the embodiments of the light redirecting flange, it may assist the reader to understand one or more terms used herein by way of a general description of the terms in the following paragraphs. 
     The term ‘redirecting,’ as used herein may generally refer to any appropriate change in direction of light. In some embodiments, redirection may include any appropriate deflection and/or reflection of light. The redirection of light can be achieved in many different ways, some of which may include, but are not limited to, using a reflective coating on a surface to redirect light, using appropriate metal that causes redirection of light, using any appropriate paints of various color, and so on. Further, the characteristics of the surface, such as size and shape of a surface that redirects light, and/or the characteristics of the coating on the surface, such as color, etc., may affect the redirection characteristics of the surface. For example, a surface coated with black paint may redirect light differently than a surface coated with white paint. 
     In the following paragraphs, the present disclosure will be described in further detail by way of examples with reference to the attached drawings. In the description, well known components, methods, and/or processing techniques are omitted or briefly described so as not to obscure the disclosure. As used herein, the “present disclosure” refers to any one of the embodiments of the disclosure described herein and any equivalents. Furthermore, reference to various feature(s) of the “present disclosure” is not to suggest that all embodiments must include the referenced feature(s). 
     The present disclosure provides an example light redirecting flange that is integral with or coupled to an end plate of a luminaire&#39;s door frame assembly. In particular, the light redirecting flange may be configured to redirect light exiting through a notch in the end plate towards a lens of the luminaire. The notch in the end plate may be formed to accommodate a portion of a light emitting diode (LED) circuit board that extends beyond the end plate of the luminaire when the LED circuit board is installed in the luminaire. However, the notch may create a dark spot in the luminaire. The dark spot created by the notch may be reduced or eliminated by the light redirecting flange through a redirection of light exiting the notch—consequently achieving a more even distribution of light across the lens of the luminaire. 
     In particular, the light redirecting flange may be a portion of the end plate that diverges away from a remaining portion of the end plate at an angle to the remaining portion of the end plate. For example, the light redirecting flange may be formed by cutting a portion of the end plate to create the notch and pushing the portion, which forms the light directing flange, into a different plane that is at an angle with a plane in which a remainder portion of the end plate resides. Alternatively, the light redirecting flange may be a separate component that is coupled to the end plate. Specifically, the light redirecting flange may be coupled to the end plate at one of the edges of the end plate that defines the notch and may be inclined at an angle to the end plate such that light exiting the notch may be redirected towards the lens of the luminaire. 
     The present technology can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the technology to those having ordinary skill in the art. Furthermore, all “examples” or “exemplary embodiments” given herein are intended to be non-limiting and among others supported by representations of the present technology. 
     Turning to  FIGS. 1A-2 , these figures illustrate different perspective and exploded views of example luminaires having the light redirecting flange, in accordance with example embodiments of the present disclosure. In particular,  FIG. 1A  illustrates a perspective view of an example luminaire comprising the light redirecting flange; and  FIG. 1B  illustrates a perspective view of the example luminaire of  FIG. 1A  in which a lens of the luminaire is removed to display the light redirecting flange and an arrangement of LEDs in the example luminaire, in accordance with example embodiments of the present disclosure. Further,  FIG. 2  illustrates an exploded view of another example luminaire, in accordance with example embodiments of the present disclosure. 
     Although  FIGS. 1A-2  illustrate recessed troffer luminaires in particular, one of ordinary skill in the art can understand and appreciate that other types of luminaires can be use a light redirecting flange without departing from a broader scope of the present disclosure. Further, even though two different example luminaires as illustrated in  FIGS. 1A-2 , the description of both the luminaires ( 100   a ,  100   b ) are collectively provided below for sake of brevity and so as not to obscure the disclosure. Accordingly, luminaire  100   a  and  100   b  will be referred to as luminaire  100  in the following description. 
     Referring to  FIGS. 1A-2 , a luminaire  100  may include a housing  104  that is coupled to a door frame assembly  102  (herein referred to as ‘door frame’). In certain example embodiments, the housing  104  in unison with the door frame  102  may securely retain, inter alia, one or more light emitting diode (LED) circuit boards (herein ‘circuit boards’)  114  having one or more LEDs  116  disposed thereon, a lens  108  disposed over the LEDs  116 , and one or more reflectors  110  adjacent the lens  108 . Even though the present disclosure describes LEDs  116 , one of ordinary skill in the art can understand and appreciate that any other appropriate light source may be substituted, for example, a fluorescent lamp may be substituted, without departing from a broader scope of the present disclosure. 
     In particular, as illustrated in  FIG. 2 , the door frame  102  may include a first end plate  202 , a second end plate  204 , a first side rail  252 , and a second side rail  254 . Each side rail ( 252 ,  254 ) may include a first lateral edge  292 , a second lateral edge  294 , and longitudinal edges that extend from the first lateral edge  292  to the second lateral edge  294 . Further, each of the first end plate  202  and the second end plate  204  may include an interior surface  240  and an exterior surface  242 . The interior surface  240  and the exterior surface  242  of each end plate ( 202 ,  204 ) may be bound by a bottom edge  206 , a top edge  208 , a first side edge  210  extending from one end of the bottom edge  206  to a corresponding end of the top edge  208 , and a second side edge  212  extending from another end of the bottom edge  206  to a corresponding other end of the top edge  208 . In particular, the bottom edge  206  of the first end plate  202  may extend from a first lateral edge  292  of the first side rail  252  to the first lateral edge  292  of the second side rail  254 . Similarly, the bottom edge  206  of the second end plate  204  may extend from a second lateral edge  294  of the first side rail  252  to the second lateral edge  294  of the second side rail  254 . Alternatively, the bottom edge  206  of each end plate ( 202 ,  204 ) may extend from any appropriate portion of the first side rail  252  to a corresponding portion of the second side rail  254  and may be substantially perpendicular to both the first and the second side rails ( 252 ,  254 ). 
     In certain example embodiments, the first and second side edges  210 ,  212  of each end plate ( 202 ,  204 ) may extend substantially orthogonally away from the bottom edge  206  and expand towards the top edge  208  giving the end plate a trapezoidal shape. However, in other example embodiments, the end plates ( 202 ,  204 ) can have any other appropriate geometric or non-geometric shape without departing from a broader scope of the present disclosure. For example, the end plates ( 202 ,  204 ) may be rectangular shaped where the side edges  210 ,  212  of the each of the first and second end plates ( 202 ,  204 ) do not taper from the bottom edge  206  to the top edge  208 . In another example, the side edges  210 ,  212  of the end plates ( 202 ,  204 ) may taper from a bottom edge  206  to the top edge  208 . 
     In certain example embodiments, each end plate ( 202 ,  204 ) of the door frame  102  may be fabricated from plastic, which is injection molded according to some exemplary embodiments. However, other suitable materials, such as aluminum, other metals, metal alloys, or other polymer types, may be used to fabricate the end plates ( 202 ,  204 ) in other example embodiments. Regardless of the material chosen to fabricate the end plates ( 202 ,  204 ), at least a portion of the interior surface  240  of the each end plate ( 202 ,  204 ) may be adapted to redirect light. For example, at least a portion of the interior surface  240  may be made reflective by polishing, painting with a reflective material, such as a white paint, or made to be reflective using any other methods known to people having ordinary skill in the art. Alternatively, according to some example embodiments, the interior surface  240  of the end plates ( 202 ,  204 ) may be non-reflective. 
     As illustrated in  FIG. 2 , each end plate ( 202 ,  204 ) further includes an embossment  160  formed within the interior surface  240  to receive and retain an edge of the lens  108 . That is, the embossment  160  facilitates positioning of the lens  104  within the door frame  102  and also provides support to the lens  108  once positioned within the door frame  102 . However, in some example embodiments, the lens  108  may be retained and supported within the door frame  102  using any other appropriate mechanism in addition to or instead of the embossment  160  without departing from a broader scope of the present disclosure. 
     Furthermore, each end plate ( 202 ,  204 ) may include a light redirecting flange  112 , where the light redirecting flange  112  may be a portion of the respective end plate ( 202 ,  204 ) that diverges away from a remainder portion the respective end plate ( 202 ,  204 ) at an angle to the remainder portion of the respective end plate ( 202 ,  204 ) as illustrated in  FIG. 2 . For example, the light redirecting flange  112  of the first end plate  202  may be a portion of the first end plate  202  that diverges away from a remainder portion of the first end plate  202  at an angle to the remainder portion of the first end plate  202 . Alternatively, the light redirecting flange  112  may not be a part of the end plate  202 . That is, the light redirecting flange  112  may be a separate independent component that may be coupled to the end plate  202  as desired. 
     The term “remainder portion of the end plate,” as used herein may generally refer to any appropriate portion of the end plate other than the portion that diverges away from the end plate. That is, the term “remainder portion of the end plate,” as used herein may generally refer to any appropriate portion of the end plate other than the light redirecting flange  112 . Herein, the light redirecting flange  112  may be interchangeably referred to as light flange  112 . Although, the present disclosure describes that each end plate ( 202 ,  204 ) includes the light redirecting flange  112 , one of ordinary skill in the art can understand and appreciate that in some embodiments, only one of the end plates may include the light redirecting flange  112  without departing from a broader scope of the present disclosure. 
     As illustrated in  FIG. 2 , the light flange  112  may include a first edge  272 , a second edge  274  opposite to the first edge  272 , a first side edge  276 , and a second side edge  278 . In particular, the first side edge  276  of the light flange  112  extends from one end of the first edge  272  to a corresponding end of the second edge  274 , and the second side edge  278  of the light flange  112  extends from another end of the first edge  272  to a corresponding other end of the second edge  274 . As illustrated in  FIG. 2 , in one example embodiment, the light flange  112  may taper from the first edge  272  to the second edge  274 . However, one of ordinary skill in the art can understand and appreciate that the light flange  272  illustrated in the figures of the present disclosure is an example and does not limit the size and shape of the light flange  112 . That is, the light flange  112  may have any appropriate geometric or non-geometric shape without departing from a broader scope of the present disclosure. The light flange  112  will be described in greater detail below in association with  FIG. 3 . However, before turning to  FIG. 3 , the housing  104  of the luminaire  100  may be described in greater detail below. 
     As illustrated in  FIG. 2 , the housing  104  of the luminaire  100  may include, inter alia, a first housing end plate  222 , a second housing end plate  224  that is opposite to the first housing end plate  224 , and a top portion  106  extending from a top edge (not shown in Figures) of the first housing end plate  222  to a top edge (not shown in Figures) of the second housing end plate  224 . The top portion  106  of the housing  104  may include an exterior major surface (not shown in the Figures) and an interior major surface  118 . Similarly, each of the first housing end plate  222  and the second housing end plate  224  may include an interior surface  226  and an exterior surface  228 . Other components of the housing are omitted from the description so as not to obscure the disclosure. 
     In certain example embodiments, the housing  104  may be coupled to the door frame  102  such that the housing end plates  222  and  224  of the housing  104  fit over and overlap the respective end plates  202  and  204  of the door frame  102 . That is, when the housing  104  is coupled to the door frame  102 , the interior surface  226  of each housing end plate  222 ,  224  is positioned adjacent to and faces the exterior surface  242  of the respective end plates ( 202 ,  204 ) of the door frame  102 . Further, in certain example embodiments, the circuit boards  114  are coupled to the interior major surface  118  of the top portion  106  of the housing  104  using fasteners  214 , as illustrated in  FIG. 2 . However, in other example embodiments, any other appropriate coupling mechanisms may be used to couple the circuit boards  114  to the housing  104 . Further, although a specific configuration of different components, such as the door frame  102 , the housing  104 , the circuit board  114 , the lens  108 , the reflectors  110 , etc., of the luminaire  100  is described herein, one of ordinary skill in the art can understand that a different configuration than that illustrated in the example figures of the present disclosure may be substituted without departing from a broader scope of the present disclosure. 
     Now turning to  FIGS. 3A-3D , these figures illustrate different views of the door frame assembly of the luminaire, in accordance with example embodiments of the present disclosure. In particular,  FIG. 3A  illustrates a top view of the door frame  102  along with the circuit boards;  FIG. 3B  illustrates a perspective view of the door frame  102  along with the circuit boards;  FIG. 3C  illustrates a cross-sectional side view of the door frame along with the circuit boards; and  FIG. 3D  illustrates a close up view of one of the end plates of the door frame along with the circuit boards, in accordance with example embodiments of the present disclosure. 
     Although the door frame  102  includes two end plates ( 202 ,  204 ), hereinafter, the description of both end plates ( 202 ,  204 ) is collectively provided below for the sake of brevity and so as not to obscure the disclosure. Similarly, although the door frame  102  includes two side rails  252 ,  254 , hereinafter, the description of both side rails  252 ,  254  is collectively provided below for the sake of brevity and so as not to obscure the disclosure. Accordingly, end plates  202  and  204  will be referred to as end plate  202 , and side rails  252  and  254  will be referred to as side rail  252  in the following description. 
     Referring to  FIGS. 3A-3D , the end plate  202  includes a notch  312  that is formed to allow placement of the one or more circuit boards  114  that extend into an area that the door frame  102  encloses when the door frame  102  is coupled to the housing  104 . As illustrated in the example embodiment of  FIG. 3A , the longitudinal length  306  of a circuit board  114  (referred to as length d 2 ) may be greater than the longitudinal distance  304  between the two opposite end plates  202  and  204  (referred to as length d 1 ). Accordingly, the notch  312  may be formed in the end plates ( 202 ,  204 ) to accommodate the ends  302  of the circuit board  114  that extend beyond the longitudinal distance d 1  between the two opposite end plates  202  and  204  of the door frame  102 . 
     In particular, the circuit boards  114  are positioned such that they are adjacent to and extend over the top edges  208  of the end plates ( 202 ,  204 ). Accordingly, the notch  312  is formed at the top edge  208  of end plates ( 202 ,  204 ). In certain example embodiments, as illustrated in  FIG. 3D , the notch  312  may include a base edge  374 , where the base edge  374  may be offset above the bottom edge  206  of the end plate  202 . That is, the base edge  374  of the notch  312  may be positioned on the end plate  202  at a distance ‘d’ above the bottom edge  206  and/or the slot  160  of the edge plate  202 . The distance d may be determined based on the desired depth and/or shape of the notch  312  and/or the shape of the light flange  112 . Further, the notch  312  may include two side edges  376  that extend towards and through a portion of the top edge  208  of the end plate  202  from either ends of the base edge  374 . In other words, the notch  312  extends from a portion of the top edge  208  of the end plate  202  through the base edge  374  on the end plate  202 . In an example embodiments, the side edges  376  and the base edge  374  of the end plate  202  define the notch  312 . 
     In some embodiments, the side edges  376  of the notch  312  may extend towards the top edge  208  of the end plate  202  at an angle with respect to the base edge  374  as illustrated in  FIGS. 1B, 2, 3B, and 4B , i.e., the notch  302  can taper or expand from the base edge  374  towards the top edge  208  of the end plate  202 . However, in other example embodiments, the side edges  376  of the notch  312  may extend substantially perpendicular to the base edge  374 . 
     Although the present disclosure illustrates and describes the notch  312  as being formed at a top edge  208  of the end plate  202  to accommodate LED circuit boards  114 , one of ordinary skill in the art can understand and appreciate that the notch can be formed at any other appropriate portion of the end plate  202  to accommodate any other appropriate component of the luminaire without departing from a broader scope of the present disclosure. Further, even though the present disclosure illustrates and describes the notch  312  as being open on one side and enclosed on the other sides by the base edge and the side edges, one of ordinary skill in the art can understand and appreciate that in some embodiments, the notch may be fully enclosed, may have any number of edges, and/or may have any appropriate shape without departing from a broader scope of the present disclosure. For example, the notch  312  may be a V-shaped notch that does not include a base edge  374 . 
     In certain example embodiments, the notch  312  in the end plate  202  may create a dark spot in the luminaire  100  as some of the light from the LEDs  116  on the circuit board  114  exits through the notch  312  rather than the lens  108  disposed over the LEDs  116 . The dark spot may create uneven illumination of the luminaire  100  across the lens  108  of the luminaire  100 . Further, the notch  312  may also compromise a light output, a light distribution efficacy, and an aesthetic look of the luminaire  100 . 
     To address the above-mentioned issues resulting from the notch  312 , as illustrated in  FIGS. 3A-3D , the end plate  202  may include a light flange  112  that is either integral with or coupled to the end plate  202 . In particular, the light flange  112  may be positioned adjacent to the notch  312  of the end plate  202  and positioned at an angle to the end plate  202  to redirect the light exiting through notch  312  towards the lens  108  of the luminaire  100 , as illustrated using example light rays  310  in  FIG. 3C . This redirected light may reduce or eliminate the dark spot resulting from the notch  312 , provide even distribution of light across the lens  108  of the luminaire  100 , increase the light distribution efficacy, and improve aesthetic looks of the luminaire  100 . 
     In certain example embodiments, the light flange  112  may be formed by cutting a portion of the end plate  202  to form the notch  312  beginning at the top edge  208  of the end plate  202  and extending to the base edge  374  of the notch  312  on the end plate  202 . Further, the portion of the end plate  202  that is cut to form the notch  302  is pushed to diverge away from a remainder portion of the end plate  202  and rest at an angle with respect to the remainder portion of the end plate  202  as illustrated in  FIGS. 3C and 3D . The portion that is cut and pushed to diverge away from the remainder portion of the end plate  202  forms the light flange  112 . Alternatively, the portion may be cut out and separated from the end plate  202  to form the notch  312 . Further, the cut out and separated portion may be coupled to the end plate  202  as the light flange  112 . Accordingly, the shape of the light flange  112  may substantially match a shape of the notch  312 , in some embodiments. However, in other example embodiments, the shape of the light flange  112  may be different from the shape of the notch  312 . 
     In some example embodiments, if the light flange  112  is pushed back into the plane in which the remainder portion of the end plate  202  resides, there may be a gap between the side edges  276  and  278  of the light flange  112  and the respective side edges  376  of the notch  312 . However, in other example embodiments, there may be no gaps between the side edges  276  and  278  of the light flange  112  and the respective side edges  376  of the notch  312  when the light flange  112  is pushed back into the plane in which the remainder portion of the end plate  202  resides. 
     In the example embodiment where the light flange  112  is formed by cutting a portion of the end plate  202  to form the notch  312  and pushing the portion to diverge away from a remainder portion of the end plate  202 , the light flange  112  may be integral with the end plate  202  at a base edge  374  of the notch  312  in the end plate  202 . Accordingly, the light flange  112  may be inclined upwardly away from the top edge  208  of the end plate  202 . For example, the first edge  272  and the side edges  276 ,  278  of the light flange  112  may extend away from the top edge  208  of the end plate  202  while the second edge  274  of the light flange  112  remains integral with the base edge  374  of the notch  312  in the end plate  202 . 
     In an alternative example embodiment, the light flange  112  may be a separate single-part or multi-part component that is coupled at an angle to the end plate  202  adjacent to the notch  312  of the end plate  212  to redirect light exiting through the notch  312  of the end plate  202  towards the lens  108  of the luminaire  100 . In one example, as described above, the second edge  274  of the light flange  112  may be coupled to the base edge  374  of the notch  312  while the first edge  272  of the light flange  112  extends away from the top edge  208  of the end plate  202 . In other words, the light flange  112  is coupled to the end plate  202  such that the light flange  112  diverges away from the end plate  202  and is inclined in an upward direction forming an angle with the end plate  202 . One of ordinary skill in the art can understand and appreciate that any appropriate coupling mechanism, such as by welding, by using fasteners, etc. may be used to couple the light flange  112  to the end plate  202 . 
     Irrespective of whether the light flange  112  is integral with or coupled to the end plate  202 , the angle that the light flange  112  forms with the end plate  202  may depend on, but is not limited to, the notch  312 , the light flange  112  itself, a placement, position, and/or configuration of the circuit boards  114  and the LEDs  116 , a position and configuration of the lens  108  of the luminaire  100 , and a desired redirection of light from the LEDs. Further, in certain example embodiments, the light flange  112  may be inclined outwardly, i.e., towards the end plates  222  and  224  of the housing. Alternatively, in other example embodiments, the light flange  112  may be inclined inwardly, i.e., towards the lens  108  of the luminaire  100  and away from the respective end plate  222  or  224  of the housing  104 . Furthermore, although the present disclosure describes the light flange  112  as being inclined in an upward direction, one of ordinary skill in the art can understand and appreciate that in some embodiments, the light flange  112  may be inclined in any other appropriate direction without departing from a broader scope of the present disclosure. For example, the light flange  112  may be inclined in a downward direction, i.e., towards the bottom edge  206  of the end plate  202 . In said example, the notch  312  may extend from the base edge  374  toward the bottom edge  206  of the end plate  202  rather than the top edge  208  of the end plate  202 . Additionally, even though the present disclosure describes the light flange  112  as being coupled to or integral with the base edge  374  of the notch  312  in the end plate  202 , one of ordinary skill in the art can understand and appreciate that in some embodiments, any other appropriate edge of the light flange  112  may be coupled to or integral with any other appropriate edge of the notch  312  without departing from a broader scope of the present disclosure. For example, the side edge  276  of the light flange  112  may be coupled to the side edge  376  of the notch  312  instead of or in addition to coupling the second edge  374  of the light flange  112  to the base edge  374  of the notch  312 . 
     Referring to  FIG. 3B , the light flange  112  may include a first major surface  307  and a second major surface  309 , where one major surface faces an inwardly towards the circuit board  114  and the other major surface faces outwardly towards the housing  104 . The major surface facing the inward direction may be interchangeably referred to as inward facing surface of the light flange  112 , e.g., the first major surface  307 , and the major surface facing the outward direction may be interchangeably referred to as the outward facing surface of the light flange  112 , e.g., the second major surface  309 . In one example, the outward facing surface may face the end plate  222  of the housing  104  and the inward facing surface may face a direction away from the end plate  222 , i.e., towards the LEDs  116 . 
     In certain example embodiments, the light flange  112  may be fabricated using the same material as that of the end plates ( 202 ,  204 ). However, in other example embodiments, the light flange  112  may be fabricated using any appropriate material that is different from that of the end plates ( 202 ,  204 ). For example, the light flange  112  may be fabricated from plastic, which is injection molded according to some example embodiments. However, other suitable materials, such as aluminum, other metals, metal alloys, or other polymer types, may be used to fabricate the light flange  112 , in other example embodiments. Regardless of the material chosen to fabricate the light flange  112 , at least a portion of the inward facing surface  307  of the light flange  112  may be adapted to redirect light. For example, at least a portion of the inward facing surface  307  is made to be reflective by polishing, painting with a reflective material, such as a white paint, or made to be reflective using any other methods known to people having ordinary skill in the art. Alternatively, according to some example embodiments, the inward facing surface  307  of the light flange  112  may be non-reflective. 
     Further, the light flange  112  may include one or more apertures  308  that extend from the first major surface  307  through the second major surface  309 . That is the aperture  308  may be a through hole. However, in some example embodiments, the aperture  308  may be a blind hole. In particular, the one or more apertures  308  may be formed adjacent each end of the first edge  272  of the light flange  112 , as illustrated in  FIG. 3C . However, in other example embodiments, the one or more apertures  308  may be formed at any other portion of the light flange  112 . Furthermore, the one or more apertures  308  may be adapted to engage and securely retain wiring support members  402  (shown in  FIG. 5 ). For example, the aperture  308  maybe larger of smaller, and the aperture  308  may have any appropriate geometric or non-geometric shape to engage a wiring support member  402  or any appropriate component of the luminaire  100 . 
     Turning to  FIGS. 4 and 5 , these figures illustrate different views of the door frame with the wiring support members. In particular,  FIG. 4  illustrates the door frame with the wiring support members coupled to the door frame; and  FIG. 5  illustrates an example wiring support member, in accordance with example embodiments of the present disclosure. Referring to  FIGS. 4B and 5 , the wiring support members  402  may be coupled to the light flange  112  and/or the end plate  202  to securely retain and channel the electrical wires associated with the luminaire in a concealed manner. In particular, the wiring support members  402  may be coupled to the light flange  112  and the end plate  202  via the aperture  308  of the light flange  112  and via an aperture  404  of the end plate  202 , respectively, as illustrated in  FIG. 4B . 
     In particular, the example wiring support member  402  illustrated in  FIG. 5  may include a first portion  502  which includes an opening  504 . Further, the wiring support member  402  may include a second portion  506  that passes through the aperture  404  of the end plate  202  or the aperture  308  of the light flange  112  to couple to the end plate  202  or the light flange  112 , respectively. One of ordinary skill in the art can understand and appreciate any other appropriate wiring support member can be substituted without departing from a broader scope of the present disclosure. Further, even though the present disclosure describes coupling the wiring support member to the end plate and/or the light flange by engaging the second portion of the wiring support member with the aperture of the end plate and/or the light flange, one of ordinary skill in the art can understand and appreciate that in some embodiments, the light flange  112  and/or the end plates  202  may not include the apertures and any other coupling mechanisms, such as, but not limited to adhesives, welding, fasteners, etc., may be used without departing from a broader scope of the present disclosure.
