Title: Lamp retention and shielding

Description:
TECHNICAL FIELD 
     The present disclosure relates generally to lighting fixtures, and more particularly to retention of a lamp of a light fixture with an adjustable lighting structure and visual shielding of an area behind the lamp. 
     BACKGROUND 
     Some light fixtures, such as recessed light fixtures, may include an adjustable trim. An adjustable trim may allow rotation as well as tilting of a lamp (e.g., a PAR lamp) of the light fixture. To illustrate, rotation and/or tilting of the lamp of a recessed light fixture may be performed by pushing on the lamp from below the light fixture. For example, a lamp may be tilted in a particular direction by pushing upward, from below the light fixture, on a bottom surface of the lamp on one side of a pivot axis of the adjustable trim. However, exerting a force on the lamp to rotate or tilt the lamp may result in the lamp detaching from a lamp retention structure of the adjustable trim or otherwise cause the lamp to move to an undesired position relative to the adjustable trim. Removal of at least a portion of the trim may be required to reattach and/or to reposition the lamp to a desired position. Further, some adjustable trims that are tiltable (e.g., some non-spherical recessed gimbal trims) may allow people to view the inside of the recessed light fixture housing from below a ceiling when the adjustable trim is tilted. 
     Thus, a lighting structure such as an adjustable structure that reduces the chance of a lamp detaching from the lighting structure or moving to an undesirable position relative to the lighting structure may be desirable. 
     SUMMARY 
     The present disclosure relates generally to retention of a lamp of a light fixture with an adjustable lighting structure and visual shielding of an area behind the lamp. In an example embodiment, a lighting structure for a light fixture includes a trim ring, a spin ring positioned within the trim ring, and a tilt ring positioned within the spin ring and attached to the spin ring by a fastener. The tilt ring is tiltable relative to the spin ring. A first tab and a second tab extend inwardly from a wall of the tilt ring. The first tab and the second tab are positioned across from the fastener. The lighting structure further includes a lamp spring attached to the tilt ring across from the first tab and the second tab. The lamp spring is positioned to push a lamp toward the first tab and the second tab. 
     In another example embodiment, a light fixture includes a housing and a lighting structure positioned in the housing. The lighting structure includes a spin ring and a tilt ring. The tilt ring is positioned within the spin ring and attached to the spin ring by a fastener. The tilt ring is tiltable relative to the spin ring. A first tab and a second tab extend inwardly from a wall of the tilt ring. The first tab and the second tab are positioned across from the fastener. The lighting structure further includes a lamp spring attached to the tilt ring across from the first tab and the second tab. The light fixture also includes a lamp extending through the tilt ring. The lamp spring is positioned to push the lamp toward the first tab and the second tab. 
     In another example embodiment, a lighting structure for a light fixture includes a trim ring, a spin ring positioned within the trim ring, and a tilt ring positioned within the spin ring and attached to the spin ring by a fastener. The tilt ring is tiltable relative to the spin ring. The lighting structure further includes a tape attached to an inner surface of the tilt ring across from the fastener. The lighting structure also includes a lamp spring attached to the tilt ring across from the tape. The lamp spring is positioned to push a lamp toward the tape. 
     In another example embodiment, a lighting structure includes a trim ring and a spin ring positioned within the trim ring. The lighting structure further includes a tilt ring positioned within the spin ring and attached to the spin ring by a first fastener and a second fastener. The first fastener and the second fastener are across from each other. The tilt ring has a first elevated section and a second elevated section that are between the first fastener and the second fastener and across from each other. The tilt ring includes lower sections between the first elevated section and the second elevated section. The first elevated section and the second elevated section extend higher than the lower sections. The first elevated section and the second elevated section each comprise an inwardly curved section. 
     These and other aspects, objects, features, and embodiments will be apparent from the following description and the claims.

     DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS 
     In the following paragraphs, particular embodiments will be described in further detail by way of example with reference to the figures. In the description, well known components, methods, and/or processing techniques are omitted or briefly described. Furthermore, reference to various feature(s) of the embodiments is not to suggest that all embodiments must include the referenced feature(s). 
     Turning now to the drawings,  FIGS. 1A and 1B  illustrate side perspective views of a lighting structure  100  for a light fixture according to an example embodiment. As illustrated in  FIGS. 1A and 1B , the lighting structure  100  may include a trim ring  102 , a spin ring  104 , and a tilt ring  106 . The lighting structure  100  may also include a lamp spring  108 . The tilt ring  106  may be attached to the spin ring  104 , and the lamp spring  108  may be attached to the tilt ring  106 . In some example embodiments, the lighting structure  100  may include torsion springs  120 ,  122  that are attached to the trim ring  102 . 
     In some example embodiments, the spin ring  104  is positioned within the trim ring  102  and may be rotatable with respect to the trim ring  102 . To illustrate, the spin ring  104  may rest on a ledge portion of the trim ring  102 . For example, the spin ring  104  may be rotatable 360 degrees relative to the trim ring  102 . Alternatively, the spin ring  104  may be rotatable slightly less than 360 degrees relative to the trim ring  102 . For example, the spin ring  104  may be rotatable approximately 359 degrees. In some alternative embodiments, the spin ring  104  may be rotatable significantly less than 360 degrees relative to the trim ring  102 . 
     In some example embodiments, the tilt ring  106  may be positioned with the spin ring  104 . The tilt ring  106  may be attached to the spin ring  104  by a fastener  118 . The tilt ring  106  may also be attached to the spin ring by another fastener  124  (more clearly shown in  FIG. 1B ) that is across from the fastener  118 . To illustrate, the tilt ring  106  may be attached to the spin ring  104  such that the tilt ring  106  is rotatable along with the spin ring  104 . The fasteners  118 ,  124  form a pivot axis  130  such that sections of the tilt ring  106  that are on opposite sides of the pivot axis  130  move in opposite directions when the tilt ring  106  is being tilted. The fasteners  118 ,  124  may each be rivets or other types of fasteners that allow the tilt ring  106  to tilt relative to the spin ring  104  as may be contemplated by those of ordinary skill in the art without departing from the scope of this disclosure. 
     In some example embodiments, the lamp spring  108  is positioned within the tilt ring  106 . The lamp spring  108  may be attached to the tilt ring  106  by the fastener  124  as shown in  FIG. 1B . Alternatively, the lamp spring  108  may be attached to the tilt ring  106  by another fastener. 
     In some example embodiments, the lamp spring  108  may include arms  126 ,  128 . For example, the arms  126 ,  128  may extend away from the fastener  124 . The arms  126 ,  128  may be spaced from each other such that the arms  126 ,  128  can hold a lamp in the space between them. Relative to the fastener  124 , the arms  126 ,  128  may initially extent away from each other and curve toward the opposite side of the tilt ring  106 . To illustrate, the arms  126 ,  128  may form a U-shaped spring. The arms  126 ,  128  may be elastic such that each arm  126 ,  128  exerts a counteracting force when pushed outwardly. 
     In some example embodiments, the lamp spring  108  includes an attachment tab  132  that extends downward from the arms  126 ,  128 . For example, the fastener  124  may extend through the attachment tab  132  to attach the lamp spring  108  to the tilt ring  106 . Alternatively, the attachment tab  132  may be omitted. For example, the fastener  124  may extend through the spring at a different location to attach the lamp spring  108  to the tilt ring  106 . 
     In some example embodiments, the lighting structure  100  may include retention tabs  114 ,  116  (more clearly shown in  FIG. 1A ) that extend inwardly from a wall of the tilt ring  106 . The retention tabs  114 ,  116  may be positioned on the tilt ring  106  generally across from the fastener  124 . To illustrate, the lamp spring  108  may be positioned across from the retention tabs  114 ,  116  such that the lamp spring  108  pushes a lamp that is attached to the lamp spring  108  toward the retention tabs  114 ,  116 . 
     To illustrate, the retention tabs  114 ,  116  may be positioned to resist an upward movement of a lamp (e.g., a PAR lamp) when the lamp comes in contact with the retention tabs  114 ,  116  during an upward movement of the lamp. For example, an upward movement of a lamp that is held by the lamp spring  108  may be caused by a person pushing upward on the lamp to change the tilt angle of the lamp. During an upward movement of a lamp (e.g., a PAR lamp), the lamp may stretch out the arms  126 ,  128  of the lamp spring  108  such that the lamp spring  108  resist movement of the lamp away from the retention tabs  114 ,  116 . For example, the arms  126 ,  128  may push the lamp toward the retention tabs  114 ,  116  as the lamp moves upward. Depending on a tilt angle of the lamp and tilt ring  106 , one or both retention tabs  114 ,  116  may come in contact with the lamp and prevent further upward movement of the lamp, preventing the detachment of the lamp from the lamp spring  108 . The arms  126 ,  128  of the lamp spring  108  also serve to retain the lamp in position relative to the tilt ring  106 . 
     In some example embodiments, the retention tabs  114 ,  116  may be formed from sections of the wall of the tilt ring  106 . For example, the retention tabs  114 ,  116  may be bent inward after cutting through the wall of tilt ring  106  such that the retention tabs  114 ,  116  remain attached to the wall on one side of the retention tabs  114 ,  116 . In some alternative embodiments, the retention tabs  114 ,  116  may be welded onto the wall of the tilt ring  106 . 
     Although two retention tabs  114 ,  116  are shown in  FIG. 1A , in some alternative embodiments, the lighting structure  100  may include a single retention tab. For example, a single retention tab that horizontally extends between the positions of the retention tabs  114 ,  116  may be used. In some alternative embodiments, the retention tabs  114 ,  116  may each have a broad surface that is facing downward. In some alternative embodiments, the retention tabs  114 ,  116  may each be curved at the end distal from the wall of the tilt ring  106 . Although the retention tabs  114 ,  116  are shown as having a rectangular shape, in alternative embodiments, the retention tabs  114 ,  116  may have other shapes without departing from the scope of this disclosure. 
     In some example embodiments, the trim ring  102  includes a wall section  110  that extends generally upward. For example, the wall section may include torsion spring attachment structures for attaching the torsion springs  120 ,  122  to the trim ring  102 . The torsion springs  120 ,  122  may be used to attach the lighting structure  100  to a light fixture housing. 
     The trim ring  102 , the spin ring  104 , and the tilt ring  106 , and the lamp spring  108  may each be made from a suitable material that may be contemplated by those of ordinary skill in the art with the benefit of this disclosure. For example, the trim ring  102  may be made from plastic or another suitable material. The trim ring  102  may be made using a method such as stamping. The trim ring  102  may also be made from a die cast material. The spin ring  104 , the tilt ring  106 , and the lamp spring  108  may also be made from similar materials using one or more methods such as stamping, injection molding and die casting. In general, the spin ring  104 , the tilt ring  106 , and the lamp spring  108  may be made, for example, from die casted metal or sheet metal. 
     Because the retention tabs  114 ,  116  working in conjunction with the lamp spring  108  prevent a lamp such as a PAR lamp held by the lamp spring  108  from move upward after coming in contact with one or both of the retention tabs  114 ,  116 , the lamp remains securely retained to the lighting structure  100 . Further, because the lamp spring  108  is attached to the tilt ring  106  by the fastener  124  forming a pivot point of the pivot axis  130  and because the retention tabs  114 ,  116  are positioned close to the pivot axis  130 , the lamp spring  108  and the retention tabs  114 ,  116  are generally hidden from view from below the lighting structure  100 . 
       FIG. 2  illustrates an exploded view of a lighting structure  200  including a lamp  202  and the lighting structure  100  of  FIGS. 1A and 1B  according to an example embodiment.  FIG. 3  illustrates another exploded view of the lighting structure  200  of  FIG. 2  according to an example embodiment. As illustrated in  FIGS. 2 and 3 , the lighting structure  200  includes the lamp  202 . For example, the lamp  202  may be a PAR lamp. In some example embodiments, the lamp  202  may include a lip  204  that extends around the lamp proximal to a bottom end of the lamp  202 . Alternatively, the lip  204  may be omitted from the lamp  202 . 
     In some example embodiments, the tilt ring  106  includes a hole  206  for attaching the lamp spring  108  to the tilt ring  106  using a fastener such as the fastener  124  shown in  FIG. 1B . The hole  206  may also be used to attach the tilt ring  106  to the spin ring  104  using the fastener  124 . The tilt ring  106  may also include a corresponding hole extending through the wall of the tilt ring  106  across from the hole  206 . 
     In some example embodiments, the tilt ring  106  may include elevated sections  222 ,  224  that are between the hole  206  and the corresponding hole. The tilt ring  106  may also include a lower section  230  and a corresponding lower section  302  across from the lower section  230  that are between the elevated sections  222 ,  224 . For example, the elevated sections  222 ,  224  may each include an extended blocking section such that the elevated sections  222 ,  224  extend higher than the lower sections  230 ,  302  when the tilt ring  106  is in an untilted position shown in  FIGS. 2 and 3 . 
     In some example embodiments, the elevated sections  222 ,  224  may gradually increase in height. For example, the elevated sections  222 ,  224  may have the largest height distal from the both the hole  206  and the corresponding hole across from the hole  206 . Alternatively, the elevated sections  222 ,  224  may each have shapes other than shown in  FIGS. 2 and 3 . For example, each of the elevated sections  222 ,  224  may have a rectangular shape extending higher than the lower sections  230 ,  302 . 
     In some example embodiments, the elevated sections  222 ,  224  may be curved inward proximal to the top edge of the elevated sections  222 ,  224 . For example, the extended blocking section of the elevated sections  222 ,  224  may be curved inward. The inward curving of the elevated sections  222 ,  224  proximal to the top edge of the elevated sections  222 ,  224  allows the tilt ring  106  to have the elevated sections  222 ,  224  that extend higher than the lower sections  230 ,  302  while still being able to tilt relative to the spin ring  104 . Alternatively, the extended blocking section of the elevated sections  222 ,  224  directed inward (e.g., bent or angled inward toward the center of the tilt ring  106 ) instead of being curved inward. In some example embodiments, the tilt ring  106  may be able to tilt up to approximately 40 degrees on both sides of the pivot axis  130  shown in  FIG. 1A . 
     As illustrated in  FIGS. 2 and 3 , the lamp spring  108  includes the arms  126 ,  128 . The lamp spring  108  may also include a hole  208  formed through the attachment tab  132 . The hole  208  may be used to attach the lamp spring  108  to the tilt ring  106  using the fastener  124  or another similar fastener. In some example embodiments, the fastener  124  may securely attach the lamp spring  108  to the tilt ring  106  through the hole  208  such that the lamp spring  108  is tiltable along with the tilt ring  106 . 
     In some example embodiments, the spin ring  104  includes a hole  214  and a corresponding hole across from the hole  214 . The hole  214  and the corresponding hole may be used to attach the tilt ring  106  to the spin ring  104  using fasteners such as the fasteners  118 ,  124 . In some example embodiments, the holes  206 ,  208 ,  214  may be aligned such that the fastener  124  may be used to attach the lamp spring  108 , the tilt ring  106 , and the spin ring  104  together. 
     In some example embodiments, the spin ring  104  includes tall sections  226 ,  228 . For example, when the lighting structure  200  is assembled (for example, as shown in  FIG. 4A ), the tall section  226  of the spin ring  104  may be adjacent to the elevated section  222  of the tilt ring  106 , and the tall section  228  of the spin ring  104  may be adjacent to the elevated section  224  of the tilt ring  106 . The spin ring  104  may also include short sections  232 ,  304 . The tall sections  226 ,  228  may extend higher than short sections  232 ,  304 . 
     In some example embodiments, the tall sections  226 ,  228  may gradually increase in height. For example, the tall sections  226 ,  228  may have the largest height distal from the both the hole  214  and the corresponding hole through the spin ring  104  across from the hole  214 . Alternatively, the tall sections  226 ,  228  may each have shapes other than shown in  FIGS. 2 and 3 . For example, each of the tall sections  226 ,  228  may have a rectangular shape extending higher than the short sections  232 ,  304 . In some example embodiments, the short sections  232 ,  304  may be omitted, and the entire spin ring  104  may have the height of the tall sections  226 ,  228 . 
     In some example embodiments, the trim ring  102  may have the wall section  110 , a flange section  210 , and a ledge section that is between the wall section  110  and the flange section  210 . The trim ring  102  may include torsion spring attachment tabs such as the tab  220  for attaching torsions springs  120 ,  122  shown in  FIG. 1A . The spin ring  104  may include a bottom section  216  that is shaped to rest on the ledge portion of the trim ring  102  within the trim ring  102 . Upward movement of the spin ring  104  relative to the trim ring  102  may be limited by one or more means as may be contemplated by those of ordinary skill in the art with the benefit of this disclosure. For example, one or more tabs of the tilt ring  106  may be bent over an upper edge of the bottom section  216  to limit the upward movement of the spin ring  104 . 
       FIG. 4A  illustrates a side view of the lighting structure  200   FIG. 2  in an untilted position according to an example embodiment.  FIG. 4B  illustrates a top perspective view of the lighting structure  200  of  FIG. 4A  in a tilted position according to an example embodiment. As illustrated in  FIGS. 4A and 4B , the spin ring  104  is positioned within the trim ring  102 , and the tilt ring  106  is positioned within the spin ring  104 . The tilt ring  106  along with the lamp  202  may be tilted to the right and left of the position of the tilt ring  106  and the lamp  202  shown in  FIG. 4A . For example, in  FIG. 4B , the tilt ring  106  is shown tilted relative to the spin ring  104 . The lamp  202  which is retained by the lamp spring  108  is tilted along with the tilt ring  106 . To illustrate, the tilt ring  106  and the lamp  202  may be tilted to the position shown in  FIG. 4B  or to another position by push upward on the lamp  202  from below the lighting structure  200  to rotate the tilt ring  106  and lamp along the pivot axis  130  shown in  FIG. 1A . 
     As shown in  FIG. 4B , the lamp spring  108  holds the lamp  202 . The retention tab  116  is positioned to resist an upward movement of the lamp  202  once the lamp  202  comes in contact with the retention tab  116 . By resisting further upward movement of the lamp  202 , the retention tab  116  may prevent the lamp  202  from popping upward through the lamp spring  108 . Thus, by preventing the lamp  202  from detaching from lamp spring  108  upward, removal of the trim ring  102  from a ceiling to reattach the lamp to the lamp spring  108  may be avoided. In some example embodiments, the tilt ring  106  along with the lamp  202  may be tilted up to approximately 40 degrees on both sides of the pivot axis  130  shown in  FIG. 1A . 
       FIG. 5  illustrates a cross-sectional view of the lighting structure  200  of  FIG. 4A  according to an example embodiment. As illustrated in  FIG. 5 , the lamp  202  rests on a rim  502  of the tilt ring  106 . The arms of the lamp spring  108  are position around the lamp  202 . The elevated section  222  of the tilt ring  106  is adjacent to the tall section  226  of the spin ring  104 , and the elevated section  224  of the tilt ring  106  is adjacent to the tall section  228  of the spin ring  104 . The elevated section  222  is curved inward at the top edge of the elevated section  222 , and the elevated section  224  is curved inward at the top edge of the elevated section  224 . 
     In some example embodiments, the spin ring  104  is positioned on the ledge section  218  of the trim ring  102  that is between the wall section  110  and the flange section  210  of the trim ring  102 . For example, the bottom section  216  of the spin ring  104  may be positioned on the ledge section  218  such that the spin ring  104  can rotate relative to the trim ring  102 . The flange section  210  of the trim ring  102  is designed to be positioned below a ceiling when the lighting structure  200  is recessed behind the ceiling. When the lamp  202  is pushed upward from below the lighting structure  200 , the arms of the lamp spring  108  are pushed outward by the lamp, resulting in a counteracting force. When the lamp  202  moves upward such that the lamp  202  comes in contact with one or both retention tabs  114 ,  116  shown in  FIG. 1A , one or both of the retentions tabs  2  in conjunction with the lamp spring  108  may prevent the lamp  202  from detaching upward from the lamp spring  108  and the tilt ring  106 . 
       FIG. 6  illustrates a cross-sectional view of the lighting structure of  FIG. 4A  with the lamp  202  in a tilted position according to an example embodiment. As illustrated in  FIG. 6 , the bottom edge  604  of the tilt ring  106  remains below a top edge  606  of the tall section  226  when the tilt ring  106  and the lamp  202  are fully tilted in a first direction, eliminating a gap that normally exists between spin rings and trim rings of typical lighting structures when the tilt rings are tilted beyond certain angles that are less than the maximum tilt angles of the tilt rings. The relative positions of the bottom edge  602  of the tilt ring  106  and the top edge  606  of the tall section  226  of the spin ring  104  limits the view into the back of the lighting structure  200  from under the lighting structure  200 . 
     In some example embodiments, the top edge  608  of the elevated section  224  of the tilt ring  106  is generally aligned with a bottom end of the bottom section  218  of the spin ring  104 , which leaves a small gap  602  between the top edge  608  and the spin ring  104 . Because the elevated section  224  and the tall section  228  extend higher than corresponding sections of tilt rings and spin rings that are used in typical lighting structures, the view into the back of the lighting structure  200  through the gap  602  from under the lighting structure  200  is limited. Because the elevated section  224  is curved inward proximal to the top edge  608 , the tilt ring  106  may be tilted up to typical tilt angles such as 40 degrees. When the tilt ring  106  and the lamp  202  are tilted in the opposite direction, the tilt ring and the spin ring  104  function in a similar manner as described with respect to  FIG. 6  to limit view into the back side of the lighting structure  200 , such as into the recessed housing of a light fixture that includes the lighting structure  200 . 
       FIG. 7  illustrates a side perspective view of a lighting structure  700  for a light fixture according to another example embodiment. The lighting structure  700  is substantially the same as the lighting structure  100 . As illustrated in  FIG. 7 , the lighting structure  700  includes a tape  702  instead of the retention tabs  114 ,  116  shown in  FIG. 1A . In general, the tape  702  is positioned to resist an upward movement of a lamp, such as the lamp  202  shown in  FIG. 2 , during adjustment of the tilt ring  106  and the lamp to adjust the tilt angle of the lamp. 
     As illustrated in  FIG. 7 , the lighting structure  700  includes the trim ring  102 , the spin ring  104 , and the tilt ring  106  positioned within the spin ring  104 . The lamp spring  108  is attached to the tilt ring  106  as describe above across from the tape  702 . The tape  702  may be a silicon tape. Alternatively, the tape  702  may be made from foam that is attached to the inner surface of the tilt ring  106 . For example, the tape  702  may be attached to the tilt ring  106  using a heat resistant adhesive or other means as may be contemplated by those of ordinary skill in the art with the benefit of this disclosure. 
     To illustrate, when a lamp that is attached to the lamp spring  108  is pushed upward from below the lighting structure  700  to adjust the tilt angle of the lamp, the tape  702  in conjunction with the lamp spring  108  resist the upward detachment of the lamp from the lamp spring  108 . To illustrate, once a portion of the lamp (e.g., the lip  204  shown in  FIG. 2 ) comes in contact with the tape  702 , the tape  702  may resist further movement through friction between the tape  702  and the portion of the lamp, which may prevent upward detachment of lamp and avoid removal of the trim ring  102  from a ceiling after the lighting structure  700  is installed. 
       FIG. 8  illustrates a cross-sectional view of a lighting fixture  800  including the lighting structure  200 ,  700  according to an example embodiment. As illustrated in  FIG. 8 , the lighting fixture  800  includes a housing  806  and a junction box  804 . The junction box  804  may be used to make wiring connections and/or store electrical components used to provide power to the lamp  202 . 
     The lighting structure  200 ,  700  is positioned in a cavity  806  of the housing  802 . A portion of the trim ring  102  (i.e., the flange section  210  shown in  FIG. 2 ) may be positioned below the housing  802  such that the portion of the trim ring  102  is below a ceiling when the housing  802  is recessed in the ceiling. 
     In some example embodiments, a socket assembly  808  or another structure may come in contact with the housing  802  to limit tiling of the lamp  202  and the tilt ring  106  beyond a desired maximum tilt angle (e.g., 40 degrees). As can be seen in  FIG. 8 , the spin ring  104  and the tilt ring  106  limit views into the cavity  806  of the housing  802  from below the lighting fixture  800  when the lamp  202  and the tilt ring  106  are fully tilted as shown in  FIG. 8 . Further, because the retentions tabs  114 ,  116  shown in  FIG. 1A  and the tape  702  shown in  FIG. 7  operate in conjunction with the lamp spring  108  to resist detachment of the lamp  202  from the lamp spring  108  when the lamp  202  is pushed from below the change the tilt angle of the lamp  202 .
