For example, one or more of the vertical rails  46   a,    46   b,  the horizontal racks  44 , and may include a metal (e.g., steel or stainless steel), a metal with a ceramic overlay, and/or a chrome plated steel or a stainless steel (for use with ovens that include pure steam functionality). 
     Referring again to  FIGS.  1 - 3   , a convection fan  56  may be concealed behind a baffle cover  58  extending from the back wall  18  into the cooking cavity  14 . During operation of the convection fan  56 , movement of cavity air within the cooking cavity  14  generates a high pressure space  60  between the baffle cover  58  and the back surface of the cooking cavity  14 . To assist in forming this high pressure space  60 , the baffle cover  58  defines a plurality of vent apertures  62  that cooperate with the convection fan  56  to generate the high pressure space  60  that directs the cavity air from the cooking cavity  14 . 
     As exemplarily illustrated in  FIGS.  1 - 3   , a lighting assembly  28  is coupled to the back wall  18  adjacent the upper portion  20  and is configured to project light into the cooking cavity  14 . Although the lighting assembly  28  is shown disposed adjacent the upper portion  20 , it should be appreciated that the lighting assembly  28  can, additionally or alternatively, be coupled to the upper portion  20 . The lighting assembly  28  may be disposed above the ladder rack assembly  42  and have a substantially elongated shape, as illustrated. The lighting assembly  28  may extend between a first end  66 , disposed adjacent the first side wall  30 , and a second end  68 , disposed adjacent the second side wall  32 . According to various aspects of the disclosure, the lighting assembly  28  may be disposed horizontally and have a length L substantially equal to a width of the baffle cover  58 . Although the lighting assembly  28  is illustrated spaced from the top wall  22 , it should be appreciated that the lighting assembly  28  may coincide with a first intersection  70  between the top wall  22  and the back wall  18  and/or a second intersection  72  between the bottom wall  26  and the back wall  18 . Further, the first end  66  of the lighting assembly  28  may be disposed in or near a first corner  74  formed by the top wall  22 , the back wall  18 , and the first side wall  30 , and the second end  68  of the lighting assembly  28  may be disposed in or near a second corner  76  formed by the top wall  22 , the back wall  18 , and the second side wall  32 . Additionally or alternatively, the lighting assembly  28  may be disposed in or near a third corner  78  formed by the bottom wall  26 , the back wall  18 , and the first side wall  30 , and the second end  68  of the lighting assembly  28  may be disposed in or near a fourth corner  80  formed by the bottom wall  26 , the back wall  18 , and the second side wall  32 . Additionally, or alternatively, the lighting assembly  28  may mount to the fillet  50  at an acute angle relative to the back wall  18 , the top wall  22 , the bottom wall  26 , and/or the first and second side walls  30 ,  32 . 
     The lighting assembly  28  may include a cover  82  made from a suitable heat resistant material (e.g., borosilicate glass, an opalescent material, etc.). The cover  82  may be optically translucent according to various aspects of the present disclosure. It should be appreciated that the cover  82  may be heat-treated to withstand high temperatures of the cooking cavity  14 . The cover  82  may serve as a light guide to diffuse or otherwise affect light provided by the lighting assembly  28 . Stated differently, the cover  82  may serve as a lens for the lighting assembly  28 . The cover  82  may be removable for ease of cleaning the cover  82 . 
     The cover  82  may include a light projection surface S configured to collimate light toward the central portion of the cooking cavity  14 . The light projection surface S includes a planar extent  82   a  that extends at an acute angle relative to the back wall  18 . The planar extent  82   a  may extend at least partially along the length L of the lighting assembly  28 . Top and bottom side extents  82   b,    82   c  may extend from the planar extent  82   a  toward the back wall  18  to connect the cover  82  with the back wall  18 . The top and bottom side extents  82   b,    82   c  may also be configured to direct light toward the central portion. Additionally or alternatively, the cover  82  may be curved between the top and bottom side extents  82   b,    82   c.  A first end extent and a second end extent may extend between the top extent  82   b  and the bottom extent  82   c  and correspond with the first end  66  and the second end  68  of the lighting assembly  28 , respectively. The lighting assembly  28  may include one or more light sources  84 , such as light-emitting diodes (LEDs). The one or more LEDs may include an LED strip disposed within the elongated lighting assembly  28 . A controller  85  may be configured to operate the LEDs to have one or more predetermined behaviors (e.g., blinking, changing colors, and changing brightness). The controller  85  may be in communication with, or may be the same as, the cooking appliance controller, and may be operable via an human-machine interface (HMI)  86  external to the cooking cavity  14 . According to some aspects of the disclosure, the light source  84  may be in a traditional tube form (similar to fluorescent bulbs), such as an LED tube, having sockets disposed at the first end  66  and the second end  68  of the lighting assembly  28 . The light source  84  may extend from adjacent the first side wall  30  to adjacent the second side wall  32 . Additionally, or alternatively, the lighting assembly  28  may incorporate a light source  84  including strip-type LED strands. 
     According to an exemplary aspect of the disclosure shown in  FIG.  2   , the lighting assembly  28  may include a first light source  84   a  and a second light source  84   b.  The first light  84   a  source can be disposed adjacent an intersection of the back wall  18 , the top wall  22 , and the first side wall  30  of the cabinet (i.e., the first corner  74 ), and the second light source  84   b  can be disposed adjacent an intersection of the back wall  18 , the top wall  22 , and the second side wall  32  of the cabinet  12  (i.e., the second corner  76 ). According to some aspects of the present disclosure, a plurality of light sources  84  may be distributed along a width of the back wall  18  between the first side wall  30  and the second side wall  32 . For example, the length L of the lighting assembly  28  may extend in a width-wise direction along the back wall  18 . The back wall  18  may generally be planar in shape. 
     Referring now to  FIGS.  4 - 7   , the lighting assembly  28  is configured to project light, illustrated by arrow  88 , at a projection angle Θ that is an acute angle relative to the back wall  18 . The light may be directed toward the central portion of the cooking cavity  14 . As previously discussed, the central portion may correspond to a location of the horizontal racks  44 . For example, the lighting assembly  28  may be configured to project the light from the upper portion  20  of the back wall  18  toward the bottom wall  26  at an acute angle relative to the back wall  18  and onto the horizontal racks  44 . The light may have a high-intensity range of light  90  and a low-intensity range of light  92 , with the high-intensity range of light  90  focused on the central portion and the low-intensity range  92  dispersed throughout the cooking cavity  14 . The lighting assembly  28  can thereby be configured to minimize glare and/or dazing light distributed at the opening  16 . 
     A support surface  94  can be disposed on the back wall  18  and extend at an acute angle relative to the back wall  18  of the cabinet  12 . The support surface  94  may be recessed or protruding from a back surface of the back wall  18 . The back surface may be the generally planar surface that is generally the rear-most portion of the cabinet  12 . The lighting assembly  28  may be coupled to the support surface  94  and configured to project light normal to the support surface  94 . As exemplarily illustrated in  FIG.  4   , the support surface  94  may be formed on a protrusion  96  extending from the back wall  18  into the cooking cavity  14 . According to aspects of the disclosure, the cover  82  of the lighting assembly  28  may be flush with the support surface  94  and the light source  84  (and/or the first and second light sources  84   a,    84   b ) may be disposed in a recess  98 , or indentation, defined by and/or extending into the back wall  18  adjacent the support surface  94 , as generally shown in  FIG.  6   . As illustrated in  FIG.  5   , the cover  82  of the lighting assembly  28  may also be housed within the recess  98 . It should be appreciated that the acute angle at which the support surface  94  extends may complementarily relate to the projection angle Θ. For example, if the support surface  94  extends at an angle of 30 degrees relative to the back wall  18 , then the projection angle Θ may be configured to project at an angle of 60 degrees relative to the back wall  18 . More particularly, continuing with the non-limiting example, the high-intensity range of light  90  may have a center ray of light  100  projecting at an angle of 60 degrees relative to the back wall  18 . 
     Referring more specifically to  FIG.  7   , the cover  82  may extend at an acute angle relative to the back wall  18  to direct the light from the light source  84  toward the central portion of the cooking cavity  14 . More specifically, the light projection surface S may extend at an acute angle relative to the back wall  18 . According to some aspects of the present disclosure, the center ray of light  100  may be configured to project generally perpendicular to the back wall  18  over a distance D 1  from the light source  84  to the cover  82 . Further, the light source  84  (and/or the first and second light sources  84   a,    84   b ) may be spaced from the cover and operable to direct the central ray of light  100  at an acute angle relative to the planar extent  82   a.  It is generally contemplated that one or both of the top and bottom side extents  82   b,    82   c  may extend generally perpendicular to the back wall  18  and be at least partially disposed within the recess  98 . The cover  82  may be operable to collimate the light about a focus angle β relative to the back wall  18 . In this way, the projection angle Θ formed between the support surface  94  and the center ray of light  100  may be in the range of between 0 degrees (i.e. parallel) and 90 degrees relative to the back wall  18  while still providing focused light into/onto the central portion of the cooking cavity  14 . Further, according to some aspects of the disclosure, the support surface  94  may be generally parallel to the back wall  18 , or, alternatively, the acute angle formed by support surface  94  may be a different angle than the acute angle the cover  82  forms with the back wall  18 . It is generally contemplated that the distance D 1  may influence the breadth of the high-intensity range of light  90  (e.g., a greater distance D 1  may reduce the breadth of the high-intensity range of light  90 ). The distance D 1 may be optimized to provide the desired breadth of the high-intensity range of light  90 , such as in the range of between 45 and 90 degrees. 
     It will be contemplated from the present disclosure that, additionally or alternatively, the lighting assembly  28  can be configured to project light toward one or both of the side walls  30 ,  32  or the top wall  22 . Stated differently, the lighting assembly  28  may be disposed on the lower portion  24  and be configured to project light at an acute angle upwardly toward the top wall  22 , or the lighting assembly  28  may be generally vertically disposed adjacent one or both of the side walls  30 ,  32  and be configured to project light toward the opposing side wall. In these configurations, the high-intensity range of light  90  may be restrained from being directed toward the opening to reduce glare according to an observer outside of the cooking cavity  14  looking into the cooking cavity  14 . 
     According to one aspect of the present disclosure, a cooking appliance includes a cabinet defining a cooking cavity and an opening to allow access to the cooking cavity.
