Description
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.

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, the spring loop 357 and spring arms 355 may act together as a helical torsion spring. In various embodiments, the spring arms 355 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 350 may be configured to hold and/or retain the retrofit housing 330 within the recessed housing 205 and to hold and/or retain a surface of the trim 305 approximately or generally flush to the mounting surface 200. In example embodiments, the torsion spring 350 may be secured to the bracket 340 by a fastener 370. For example, the fastener 370 may pass at least partially through the spring loop 357 to affix and/or secure the torsion spring 350 to the bracket 340. In other examples embodiments, the torsion springs may be other spring loaded clips 350′, as shown in FIG. 7A, and/or the like as appropriate for the application.


Exemplary Fasteners

In example embodiments, the retrofit trim lighting device 300 comprises one or more fasteners (e.g., 370, 371, 372). For example, the trim 305 may be affixed and/or secured to the retrofit housing 330 by one or more fasteners 371. In another example, each torsion spring 350 may be affixed and/or secured to the bracket 340 by a fastener 370. In yet another example, the engagement element 360 may be affixed and/or secured to the retrofit housing 330 by one or more fasteners 372. In example embodiments, the one or more of the fasteners 370, 371, 372 may be screws, bolts, rivets, adhesive, and/or other mechanical fasteners appropriate for the application, and/or a combination thereof.

FIGS. 8A, 8B, 9, 10, 11A, 11B, 12A, 12B, 13, 14, 15, and 16 illustrate various views of example embodiments of a retrofit trim lighting device 100 in accordance with the present invention. In various embodiments, the retrofit trim lighting device 100 may comprise a trim 105 and a retrofit housing 110. In example embodiments, the retrofit trim lighting device 100 may further comprise one or more torsion springs 125. Each torsion spring may be slidably secured to the retrofit housing 110 by a slide 130. Various aspects of the retrofit trim lighting device 100 will now be described in more detail.


Exemplary Trim

In various embodiments, the trim 105 may be configured to provide the retrofit trim lighting device 100 with a particular aesthetic appearance when the lighting device is installed within the recessed housing 205. In various embodiments, the trim 105 may be shaped and/or styled to have an identifiable or discernible orientation. For example, the trim 105 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 105 may be secured to one end of the retrofit housing 110. For example, the trim 105 may be secured to the retrofit housing 110 such that the orientation of the trim 105 to the retrofit housing 110 is fixed and/or not changeable.


Exemplary Retrofit Housing

In various embodiments, the retrofit housing 110 may be generally cylindrical, conical, and/or a combination thereof. In various embodiments, the trim 105 may define a plane and the retrofit housing 110 may define a first axis that is generally perpendicular to the plane defined by the trim 105. For example, in some embodiments, the first axis is normal to the center point of the trim 105. 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 100 is mounted within the recessed housing 205, the first axis may be generally parallel to the second axis.


In various embodiments, the retrofit housing 110 may be configured to house a light engine 145, secondary optics 140, a power source, and/or the like. For example, in example embodiments, the retrofit housing 110 may house a light engine 145 comprising one or more light emitting diode (LED) chips, LED packages, LED modules, and/or the like. In some embodiments, the retrofit housing 110 may house a light engine 145 comprising and/or configured for receiving and/or operating a halogen, fluorescent, compact fluorescent, incandescent, or other lamp or light bulb.

In some embodiments, the one or more slots 120 are disposed in the transition or hip portion 115 of the retrofit housing 110.


In various embodiments, the one or more slots 120 are configured for securing therethrough one or more slides 130 to the retrofit housing 110. For example, each slot 120 may have a slide 130 secured therethrough such that the slide 130 is slidably secured to the retrofit housing 110. For example, the slide 130 may be configured to slide along the length, or at least a portion of the length, of the corresponding slot 120. 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

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.
