     BACKGROUND 
     In general, recessed lighting allows a lighting device to be mounted within a recessed housing that is recessed within a mounting surface such as a ceiling or wall. A retrofit trim lighting device may be mounted within a recessed housing such that an aesthetic trim is generally flush with the mounting surface. If the trim is generally round, the orientation of the trim with respect to the recessed housing is generally unimportant. However, for various trim shapes (e.g., square, oval, triangular, and/or the like), the orientation of the trim with respect to the recessed housing and/or with respect to the trim of other nearby recessed lighting devices may be important. 
     Thus, there is a need in the art for improved retrofit trim lighting devices and methods of mounting retrofit trim lighting devices that allow the trim orientation to be easily adjusted. 
     BRIEF SUMMARY 
     Example embodiments of the present invention provide a rotatable retrofit trim lighting device. In particular, various embodiments of the present invention provide a retrofit trim lighting device configured to be mounted within a recessed lighting housing by, for example, torsion spring(s). In example embodiments, the orientation of the retrofit trim lighting device may be adjusted and/or rotated with respect to the recessed housing after installment of the retrofit trim lighting device within the recessed housing. 
     According to an aspect of the present invention, a retrofit trim lighting device is provided. In an example embodiment, the retrofit trim lighting device comprises a bracket comprising an opening; at least one torsion spring secured to the bracket and configured to mount the retrofit trim lighting device within a recessed housing; a retrofit housing comprising at least one light engine; and an engagement element. The engagement element is secured to the retrofit housing through the opening of the bracket such that, when so secured, the retrofit housing and the bracket are rotatable relative to one another. 
     According to another aspect of the present invention, a retrofit trim lighting device is provided. In an example embodiment, the retrofit trim lighting device comprises a bracket for mounting the retrofit trim lighting device. The bracket comprises an opening and a planar portion. The planar portion defines a bracket plane. The opening defines a rotation axis that passes through the center of the opening and that is normal to the bracket plane. The retrofit trim lighting device may further comprise a retrofit housing comprising at least one light engine; and an engagement element. The engagement element is secured to the retrofit housing through the opening of the bracket such that, when so secured, the retrofit housing and the bracket are rotatable relative to one another, with the rotation being about the rotation axis. 
     According to yet another aspect of the present invention, a lighting kit for a retrofit trim lighting device is provided. In example embodiments, the lighting kit comprises a retrofit housing comprising at least one light engine and having a frame affixed thereto; a bracket comprising an opening; and an engagement element.

     I. EXEMPLARY EMBODIMENT OF A RETROFIT TRIM LIGHTING DEVICE 
       FIGS. 2, 3, 4, 5, 6, and 7A  illustrate various views of example embodiments of a retrofit trim lighting device  300 . In various embodiments, the retrofit trim lighting device  300  may comprise a trim  305 , a retrofit housing  330 , a bracket  340 , and an engagement element  360 . In example embodiments, the retrofit trim lighting device  300  may comprise one or more torsion springs  350 . For example, the one or more torsion springs  350  may be affixed and/or secured to the bracket  340 . In example embodiments, the engagement element  360  may be affixed and/or secured to the retrofit housing  330  such that at least a portion of the bracket  340  is sandwiched between the retrofit housing  330  and the engagement element  360 . Moreover, in example embodiments, the engagement element  360  is affixed and/or secured to the retrofit housing  330  such that the bracket  340  is secured between the engagement element  360  and the retrofit housing  330  and the retrofit housing  330  and the engagement element  360  may rotate with respect to the bracket  340 . Various aspects of the retrofit trim lighting device  300  will now be described in more detail. 
     Exemplary Trim 
     In various embodiments, the trim  305  may be configured to provide the retrofit trim lighting device  300  with a particular aesthetic appearance when the lighting device is installed within the recessed housing  205 . In various embodiments, the trim  305  may be shaped and/or styled to have an identifiable or discernible orientation. For example, the trim  305  may be generally square-shaped, triangularly-shaped, oval-shaped, be decorated by a design that in shape or color provides an identifiable or discernible orientation, and/or the like. The trim  305  may be secured to one end of the retrofit housing  330 . For example, the trim  305  may be secured to the retrofit housing  330  (e.g., by fasteners  371 ) such that the orientation of the trim  305  to the retrofit housing  330  is fixed and/or not changeable. 
     In example embodiments, the trim  305  may comprise one or more optical components (e.g., a lens, secondary optics, and/or the like). In some example embodiments, the retrofit trim lighting device  300  may further comprise optical element  320 . For example, the optical element  320  may be a lens, secondary optics, or other optical component configured to condition the light emitted by the one or more light emitting diode (LED) chips, LED packages, LED modules, and/or other light emitting element of the light engine  310 . In example embodiments, the trim  305  may comprise the optical element  320 . In some embodiments, the optical element  320  may be a distinct element of the retrofit trim lighting device  300 . 
     Exemplary Retrofit Housing 
     In various embodiments, the retrofit housing  330  may be generally cylindrical, conical, prismatic, and/or a combination thereof. In various embodiments, with reference in particular to  FIG. 3 , the trim  305  may define a plane and the retrofit housing  330  may define a first axis that is generally perpendicular to the plane defined by the trim  305 . For example, in some embodiments, the first axis is normal to the center point of the trim  305 . In example embodiments, the recessed housing  205  may be generally cylindrical and may define a second axis along the length thereof. When the retrofit trim lighting device  300  is mounted within the recessed housing  205 , the first axis may be generally parallel to the second axis. 
     In various embodiments, the retrofit housing  330  may be configured to house a light engine  310 , secondary optics  320 , a power source, and/or the like. For example, in example embodiments, the retrofit housing  330  may house a light engine  310  comprising one or more light emitting diode (LED) chips, LED packages, LED modules, and/or the like. In some embodiments, the retrofit housing  330  may house a light engine  310  comprising and/or configured for receiving and/or operating a halogen, fluorescent, compact fluorescent, incandescent, or other lamp or light bulb. In various embodiments, when the retrofit trim lighting device  300  is mounted within a recessed housing  205 , the light engine  310  may be configured to emit light through the secondary optics  320  and into a room or other space at least partially defined by the mounting surface  200 . In example embodiments, the secondary optics  320  may comprise a lens; decorative, translucent, and/or transparent light engine cover; light envelope; diffractive element; and/or the like. In some embodiments, the power source may comprise means for connecting the electrical components of the retrofit trim lighting device  300  (e.g., light engine, driver circuitry, and/or the like) to line voltage through the recessed housing  205 . For example, the power source may comprise electrical connecting wires configured to be connected to line voltage wires of the recessed housing  205  by wire nuts, quick connect connectors, and/or the like. In another example, the power source may comprise electrical connecting wires attached to a lamp base (e.g., an A19 base) configured to be screwed, inserted, rotated, and/or the like into a traditional lamp socket of the recessed housing  205 . In various embodiments, the electrical connecting wires may have one end within the interior of the retrofit housing  330  and in electrical communication with the light engine  310  (e.g., through driver circuitry and/or the like) and another end on the exterior of the retrofit housing  330  that is configured to connect to line voltage. In some example embodiments, the power source may be one or more batteries, a battery pack, and/or the like. 
     In example embodiments, the retrofit housing  330  is configured to be affixed and/or secured to the engagement element  360 . For example, the retrofit housing  330  may comprise one or more elements configured to permit fasteners  372  to affix and/or secure the retrofit housing  330  to the engagement element  360 . For example, the retrofit housing  330  may comprise one or more engagement holes  332  for affixing and/or securing the engagement element  360  to the retrofit housing  330 . In example embodiments, the engagement element  360  may be affixed and/or secured to the retrofit housing  330  such that the engagement element  360  and the retrofit housing  330  cannot rotate with respect to one another. For example, the engagement element  360  may be fixedly secured to the retrofit housing  330 . The bracket  340  may be sandwiched between the engagement element  360  and retrofit housing  330  such that the retrofit housing  330  and the engagement element  360  may rotate with respect to the bracket  340 . However, the bracket  340  may be secured between the engagement element  360  and the retrofit housing  330  such that the bracket cannot be moved translationally with respect to the engagement element  360  and the retrofit housing  330 . For example, the bracket  340  may be secured to the engagement element  360  and retrofit housing  330  while allowing for engagement element  360  and the retrofit housing  330  to rotate with respect to the bracket  340 . 
     In example embodiments, retrofit housing  330  may comprise a planar back surface  334 . For example, the planar back surface  334  may define a plane that is parallel to a bracket plane defined by a planar portion  341  of the bracket  340 . In general, the planar back surface  334  may be configured to abut and/or be positioned adjacent the bracket  340  (e.g., the planar portion  341 ) and allow the retrofit housing  330  to rotate freely with respect to the bracket  340 . For example, in example embodiments, the planar back surface  334  does not comprise any bumps or other elements the extend outward from the planar back surface  334  that would prevent the retrofit housing  330  from rotating with respect to the bracket  340  while abutting or positioned adjacent to the planar portion  341  of the bracket  340 . 
     Exemplary Bracket 
     As also evident in  FIG. 3 , the bracket  340  comprises a planar portion  341  and one or more spring attachment portions  342 . For example, the bracket  340  may comprise two spring attachment portions  342 , each spring attachment portion  342  configured for securing a torsion spring  350  thereto. The planar portion  341  may comprise an opening  345  configured to securing the retrofit housing  330  to the engagement element  360  therethrough. In example embodiments, the planar portion  341  may define a bracket plane. In example embodiments, when the retrofit trim lighting device  300  is mounted and/or installed within a recessed housing  205 , the bracket plane is generally parallel to a plane defined by the mounting surface  200 . In some embodiments, the bracket plane is generally parallel to a plane defined by the frame  305 . In example embodiments, the planar portion  341  may further define a bracket axis  343  that is in and/or parallel to the bracket plane. In example embodiments, the bracket  340  is made of aluminum, some other metal, or other appropriate material. 
     In example embodiments, the bracket  340  comprises one or more spring attachment portions  342 . In example embodiments, the one or more spring attachment portions  342  are generally transverse with respect to the planar portion  341 . For example, in example embodiments, the one or more spring attachment portions  342  extend outwardly from the bracket plane. In example embodiments, the spring attachment portions  342  may extend generally outwardly from the bracket plane. In an example embodiment, the spring attachment portions  342  extend perpendicularly out of the bracket plane. In an example embodiment, if the bracket  340  comprises two or more spring attachment portions  342 , the two or more spring attachment portions  342  extend outwardly in generally the same direction and/or in directions that are mirror reflections of each other with respect to a reflection plane that is perpendicular to the bracket plane and perpendicular to the bracket axis  343 . In example embodiments, the spring attachment portions  342  may extend outwardly from the planar portion  341  in the general direction of the engagement element  360 . In example embodiments, a first spring attachment portion  342  may be disposed at a first end of the planar portion  341  and a second spring attachment portion  342  may be disposed at a second end of the planar portion  341 , wherein the second end of the planar portion  341  is opposite the first end of the planar portion  341 . For example, a first spring attachment portion  342  may be disposed at a first end of the planar portion  341 . A second spring attachment portion may be disposed at a second end of the planar portion  341 , wherein the first end and the second end of the planar portion  341  are separated by a length of the planar portion  341  along the bracket axis  343 . Each spring attachment portion  342  may be configured to have a torsion spring  350  affixed and/or secured thereto by a fastener  370 .  FIG. 7B  illustrates another example embodiment of a bracket  340 ′ having three attachment portions  342  and in which the attachment portions  342  are directed in a direction from the planar portion  341  generally toward the retrofit housing  330 . 
     The planar portion  341  may comprise an opening  345  configured for mediating the securement of the retrofit housing  330  directly to the engagement element  360  and indirectly to the bracket  340 . In particular, the fasteners  372  configured to directly and fixedly secure the retrofit housing  330  to the engagement element  360  may be at least partially passed through the opening  345 . For example, the fasteners  372  may be partially disposed in the opening  345  when in a position to secure the retrofit housing  330  to the engagement element  360 . For example, the engagement element  360  may comprise a pass through portion  365  configured to extend at least partially through the opening  345  and receive the fasteners  372  therein. In example embodiments, the opening  345  defines a rotation axis  347  that is perpendicular to the bracket plane. For example, the rotation axis  347  is normal to the bracket plane and intersects the bracket plane at the central point of the opening  345 . When the retrofit housing  330  and the engagement element  360  rotate with respect to the bracket  340 , the retrofit housing  330  and the engagement element  360  may rotate about the rotation axis  347  while the bracket  340  does not rotate. In example embodiments, the opening  345  is circular. In example embodiments, the pass through portion  365  may also be generally circular in cross-section. The diameter of the opening  345  and the diameter of the pass through portion  365  may be configured such that a peripheral surface  346  of the opening engages an outer surface  366  of the pass through portion  365  such that friction between the peripheral surface  346  and the outer surface  366  causes the retrofit housing  330  to maintain a particular orientation with respect to the bracket  340  unless acted upon by an external torque (e.g., a user and/or installer rotating the trim  305  and/or the like). 
     Exemplary Engagement Element 
     In example embodiments, the engagement element  360  may comprise a planar surface  367 , a pass through portion  365 , and one or more securing portions  362 , as may be understood with reference to at least  FIG. 3 . The engagement element  360  may be configured to be affixed and/or secured to the retrofit housing  330  such that the bracket  340  is sandwiched between the retrofit housing  330  and the engagement element  360 , effectively securing the bracket  340  to the retrofit housing  330  and the engagement element  360 , while allowing the retrofit housing  330  and the engagement element  360  to rotate with respect to the bracket  340 . 
     In example embodiments, the planar surface  367  may define a plane that is parallel to the bracket plane, as may be understood with reference to—in combination— FIGS. 3 and 4 . In general, the planar surface  367  may be configured to abut and/or be positioned adjacent the bracket  340  and allow the engagement portion  360  to rotate freely with respect to the bracket  340 . For example, in example embodiments, the planar surface  367  does not comprise any bumps or other elements the extend outward from the planar surface  367  that would prevent the engagement element  360  from rotating with respect to the bracket  340  while abutting or positioned adjacent to the planar portion  341  of the bracket  340 . The dimensions of the planar surface  367  may be such that, when the engagement element  360  is positioned such that the pass through portion  365  is at least partially disposed within the opening  340 , the engagement element  360  does not engage and/or come into contact with the one or more spring attachment portions  342 , even when the engagement element  360  is rotated with respect to the bracket  340 . Moreover, the size of the engagement element  360  and/or the planar surface  367  may prevent the planar surface  367  from passing through the opening  345 . 
     The pass through portion  365  may be configured to be positioned at least partially within the opening  345  of the bracket  340 . For example, the pass through portion  365  may extend outwardly from the planar surface  367 . The pass through portion  365  may have a size and shape that allows at least a portion of the pass through portion  365  to be disposed within the opening  345 . For example, the opening  345  may be round and the pass through portion  365  may also be round. The diameter of the opening  345  and the diameter of the pass through portion  365  may be configured such that a peripheral surface  346  of the opening  345  and an outer surface  366  of the pass through portion  365  engage each other such that friction between the peripheral surface  346  and the outer surface  366  generally prevents the rotation of the pass through portion  365  with respect to the opening  345  unless an external torque is applied (e.g., the user and/or installer rotates the frame  305 , and/or the like). For example, the engagement of the peripheral surface  346  by the outer surface  366  allows the retrofit housing to be selectively rotated with respect to the housing. 
     In example embodiments, the pass through portion  365  and/or a portion of the engagement element bounded by the pass through portion  365  may comprise one or more securing portions  362 . For example, the securing portion  362  may be configured to receive, retain, and secure a portion of a fastener  372  therein such that the fasteners  372  fixedly secure the engagement portion  360  to the retrofit housing  330 . The one or more securing portions  362  may be disposed within and/or on a portion of the engagement element  360  bounded by the pass through portion  365  such that the fasteners  372  pass through and/or are accessible through the opening  345 . In particular, the securing portions  362  may receive, secure, and/or retain a portion of the fasteners  372  therein such that the fasteners pass through the opening  345  and secure the retrofit housing  330  to the engagement element  360  such that the retrofit housing  330  and the engagement element  360  sandwich the bracket  340 , thereby effectively securing the bracket  340  the retrofit housing  330  and the engagement element  360 . Moreover, the securing portions  362  may receive, secure, and/or retain a portion of the fasteners  372  therein such that the fasteners pass through the opening  345  and secure the retrofit housing  330  to the engagement element  360  such that the retrofit housing  330  and the engagement element  360  are rotatable about the rotation axis  347  with respect to the bracket  340 . While the pass through portion  365  is described herein as a portion of the engagement element  360  that extends outwardly from the planar surface  367 , in some embodiments, the pass through portion  365  may be a portion of the retrofit housing  330  and extend outwardly from the planar back portion  334 . 
     Exemplary Torsion Springs 
     In example embodiments, the retrofit trim lighting device  300  may comprise one or more torsion springs  350  each secured to the bracket  340  by a fastener  370  (see  FIGS. 3 and 5  in particular). In example embodiments, one, two, three, or four torsion springs  350  may be mounted to the bracket  340 . For example, a torsion spring  350  may be secured to a spring attachment portion  342  of the bracket  340 . The one or more torsion springs  350  may be configured to mechanically mount, secure, and/or hold the retrofit trim lighting device  300  within a recessed housing  205 . In particular, a torsion spring  350  may be configured to mount a bracket  340  within the recessed housing  205  such that rotating the trim  305  and the retrofit housing  330  with respect to the bracket  340  causes the trim  305  and the retrofit housing  330  to be rotated with respect to the recessed housing  205 . For example, the one or more torsion springs  350  may be configured to mount a bracket  340  within the recessed housing  205  such that the orientation of the trim  305  may be rotated with respect to the recessed housing  205 . 
     In example embodiments, each torsion spring  350  comprises a spring loop  357  and two spring arms  355 .

In various embodiments, a slide  130  may be configured to secure a torsion spring  125  to the retrofit housing  110 . 
     Exemplary Torsion Springs 
     In example embodiments, the retrofit trim lighting device  100  may comprise one or more torsion springs  125  slidably secured to the retrofit housing  110  by one or more slides  130 . The one or more torsion springs  125  may be configured to mechanically mount, secure, and/or hold the retrofit trim lighting device  100  within a recessed lighting device receptacle (referred to as recessed housing  205  herein). In particular, a slide  130  may be configured to secure a torsion spring  125  to the retrofit housing  110  such that the position of the torsion spring about the retrofit housing  110  may be modified by sliding the slide  130  along the slot  120 . For example, if the slots  120  are arcs, the retrofit housing  110  (and trim  105 ) may be rotated with respect to the torsion springs  125  by sliding the slides  130  along the slots  120 . An example embodiment comprises two slots  120 , two slides  130 , and two torsion springs  125 , wherein each torsion spring  125  corresponds to one slide  130  and one slot  120 . 
     In example embodiments, each torsion spring  125  comprises a spring loop  127  and two spring arms  123 . In various embodiments, the spring loop  127  and spring arms  123  may act together as a helical torsion spring. In various embodiments, the spring arms  123  may be configured to engage interior walls of a recessed housing  205  to generally hold and/or retain the retrofit trim lighting device within the recessed housing  205 . For example, the torsion springs  125  may be configured to hold and/or retain the retrofit housing  110  within the recessed housing  205  and to hold and/or retain a surface of the trim  105  approximately or generally flush to the mounting surface  200 . In example embodiments, the torsion spring  125  may be secured to the clip  130  by a slide clip  136 . For example, the slide clip  136  may engage the spring loop  127  to secure the torsion spring  125  to the slide  130 . 
     Exemplary Slide 
     In example embodiments, the slide  130  comprises a slide clip  136 , an exterior portion  132 , and an interior portion  134 . In various embodiments, the slide clip  136 , exterior portion  132 , and the interior portion  134  may be secured together by one or more fasteners  138 , adhesive, and/or the like. In various embodiments, the interior portion  134  may be positioned adjacent an interior surface  112  of the retrofit housing  110  and the exterior portion  132  may be positioned adjacent an exterior surface  114  of the retrofit housing  110 . The exterior portion  132  and the interior portion  134  of the slide  130  may be secured to each other through the slot  120 . In example embodiments, the exterior portion  132  is configured such that the exterior portion  132  generally cannot pass through the slot  120 . In example embodiments, the interior portion  134  is configured such that generally the interior portion  134  cannot as a whole pass through the slot  120 . 
     In example embodiments, the interior portion, in example embodiments, comprises a spine  135  configured to at least partially pass through the slot  120 . For example, when the slide  130  is secured to the retrofit housing  110 , a portion of the spine  135  may be within the interior of the retrofit housing  110 , a portion of the spine  135  may be within the slot  120 , and a portion of the spine  135  may be exterior to the retrofit housing  110 . In example embodiments, the exterior portion  132  is secured to the interior portion  134  through the spine  135 . In example embodiments, the spine  135  may have a generally rectangular cross-section, though other cross-sections are possible. In example embodiments, the spine  135  may have a width configured to allow the slide to easily slide along the length of the slot  120  when an installer is setting the orientation of the trim  105 , but to generally not slide along the slot  120  without the application of an intentional torque thereto. 
     In example embodiments, the exterior portion  132  comprises a channel  133  configured to receive the spine  135  therein. In various embodiments, a cross-section of the channel  133  may approximately match the corresponding cross-section of the spine  135 . It should be understood that the exterior portion  132  may comprise a spine  135  and/or the interior portion  134  may comprise a channel  133 , in various embodiments. 
     In example embodiments, when the retrofit trim lighting device  100  is mounted within the recessed housing  205 , the pressure of the torsion spring arms  123  on the walls of the recessed housing  205  may prevent the torsion springs  125  from rotating easily within the recessed housing  205 . However, the slides  130  are generally configured to slide within the slots  120 . As the slides  130  are fixedly secured to the torsion springs  125  (e.g., via spring clip  136 ), the retrofit housing  110  and the trim  105  secured thereto may be rotated with respect to the torsion springs  125  and the recessed housing  205 . For example, the retrofit housing  110  and trim  105  may be rotated with respect to the torsion springs  125  and the recessed housing  205  to place the trim  105  in a particular orientation and/or a particular orientation with respect to the trim(s)  105  of one or more other recessed lighting devices or retrofit trim lighting devices  100 . 
     III. EXEMPLARY METHOD OF INSTALLING A RETROFIT TRIM LIGHTING DEVICE 
       FIG. 17  provides a flowchart of various procedures that may be completed to install a retrofit trim lighting device  300 ,  100  within a recessed housing  205 . Starting at step  402 , an electrical connection between the retrofit trim lighting device  300 ,  100  and line voltage is established. For example, a connection between electrical connecting wires of the retrofit trim lighting device  300 ,  100  and the line voltage wires may be established. In another example, a base similar to a traditional lamp or light bulb base (e.g., an A19 base or the like) connected to electrical connecting wires of the retrofit trim lighting device  300 ,  100  may be screwed, inserted, rotated, and/or the like into a socket of the recessed housing  205  to establish a connection between the electrical components of the retrofit trim lighting device  300 ,  100  and line voltage (or an appropriate voltage source for operating the retrofit trim lighting device  300 ,  100 ). In some embodiments, the retrofit trim lighting device  300 ,  100  may be battery operated, for example, and no connection with line voltage may be established. 
     At step  404 , the spring arms  355 ,  123  of the torsion springs  350 ,  125  may be squeezed together. At step  406 , the torsion springs  350 ,  125  may be at least partially positioned within the recessed housing  205  and released. The spring arms  355 ,  123  of the torsion springs  350 ,  125  may engage the sidewalls of the recessed housing  205  to maintain the retrofit trim lighting device  300 ,  100  generally within the recessed housing  205 . 
     At step  408 , the trim  305 ,  105  and the retrofit housing  330 ,  110  may be rotated with respect to the recessed housing  205  to position the trim  305 ,  105  in a preferred or desired orientation. For example, the trim  305  and the retrofit housing  330  may be rotated with respect to the bracket  340  to position the trim  305  in a preferred or desired orientation. In another example, the trim  105  and the retrofit housing  110  may be rotated with respect to the torsion springs  125  to position the trim  105  in a preferred or desired orientation. For example, an installer may hold the trim  305 ,  105  and rotate the trim  305 ,  105  with respect to the recessed housing  205  (and the bracket  340  and/or the torsion springs  350 ,  125 ) to position the trim  305 ,  105  in a preferred and/or desired orientation. At step  410 , the retrofit trim lighting device  300 ,  100  is pushed into the recessed housing  205  until a surface of the trim  305 ,  105  adjacent the retrofit housing  330 ,  110  is approximately and/or generally flush against the mounting surface  200 . In some embodiments, step  410  may be completed before step  408 .
