RELATED PATENT APPLICATIONS 
     This patent application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application No. 61/295,044, titled “Features for Improving Installation and Light Output for LED Lighting Fixtures” and filed Jan. 14, 2010, the complete disclosure of which is hereby fully incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     Embodiments of the invention relate generally to lighting fixtures, and more particularly to features that improve the installation of lighting modules or trims with recessed light fixture housings. 
     BACKGROUND 
     Recessed lights, such as downlights, are light systems or light fixtures that are installed in a hollow opening within a ceiling, wall, or other structure. The recessed light generally includes a housing mounted in the ceiling and a lighting module removably attachable to the housing. The lighting module generally includes a light source, such as one or more light emitting diodes (“LEDs”), compact fluorescent lamps (“CFLs”), high-intensity discharge (“HID”) lamps, or incandescent lamps. When installed in the housing and powered on, the light source provides inconspicuous light that appears to shine from a hole in the ceiling or other structure where the recessed light is installed. 
     Housings for recessed lights typically include a lamp holder for holding the lighting module in place. Some conventional lamp holders employ torsion spring retainers that accept torsion springs attached to the light source. When in place in the torsion spring retainers, the torsion springs hold the lighting module in place in the housing. The torsion springs also interact with the torsion spring retainers to pull the lighting module into the housing during installation. However, the installation of lighting modules using conventional torsion springs can be clumsy and difficult for users. The design of conventional torsion spring retainers also makes the torsion springs more susceptible to slipping from the torsion spring retainers. 
     Lighting modules for recessed lights typically include an electrical connector that attaches to an electrical connector of the housing to receive power for the light source. This electrical connector of conventional lighting modules is often mounted in a vertical orientation on top of or above the lighting module&#39;s heat sink, adding height to the lighting module. The added height increases the required installation space for the recessed light. In addition, the vertical orientation of the electrical connector causes flexible conduits or cables connected to the electrical connector to extend higher above the lighting module before turning in a horizontal direction due to the required bend radius of the flexible conduit or cable. The position and vertical orientation of electrical connectors for conventional lighting modules also make it more difficult to connect the lighting module&#39;s electrical connector to the housing&#39;s electrical connector. 
     SUMMARY 
     The present invention provides improved features for installing lighting modules with recessed light fixture housings. The housing can include one or more torsion spring receivers for accepting and holding in place torsion springs coupled to the lighting module. The torsion spring receivers can include a backstop and torsion spring brackets having edges angled with respect to backstop. The angled edges can each guide a portion of a torsion spring into position in a respective hook slot formed by a retaining tab. The retaining tab can be curved to follow the profile of the lighting module&#39;s heat sink providing space for the heat sink during installation and removal of the lighting module. 
     The lighting module can include a flexible conduit connector for receiving a flexible conduit. The flexible conduit connector can include an aperture for routing electrical conductors between the outside of the lighting module and the inner portion of the lighting module. The flexible conduit connector can be disposed on an angled surface of the lighting module above the lighting module&#39;s light source and opposite the light source&#39;s direction of illumination. The surface can be angled in one or more directions to allow the flexible conduit to lay flatter when the lighting module is installed in the housing and reduce the required installation space for the housing. 
     For one aspect of the present invention, a lighting module can include a first surface having a first side and an opposing second side. A light source can be disposed along the first side. A heat sink can be disposed on the second side and opposite a direction of illumination for the light source. A flexible conduit connector can be disposed at an acute angle along at least one axis and disposed along the first surface. The flexible conduit connector can provide an aperture through the first surface for receiving electrical wiring for the light source. 
     For another aspect of the invention, a light fixture can include a housing for receiving and holding a lighting module having a light source. The light fixture also can include a torsion spring receiver coupled to the housing. The torsion spring receiver can include a backstop having a substantially straight edge, a first torsion spring bracket disposed on a first side of the backstop, and a second torsion spring bracket disposed on the first side of the backstop. The first torsion spring bracket can receive a first portion of a torsion spring. The first torsion spring bracket can include a first inner edge extending out orthogonally from the straight edge and curving to extend further from the straight edge at a first acute angle with respect to the straight edge. The first torsion spring bracket also can include a first retaining tab having a first curved edge that extends from the end of the first inner edge opposite the straight edge to form a first area for receiving the first portion. The second torsion spring bracket can receive a second portion of the torsion spring. The second torsion spring bracket can include a second inner edge extending out orthogonally from the straight edge and curving to extend further from the straight edge at a second acute angle with respect to the straight edge. The second torsion spring bracket also can include a second retaining tab having a second curved edge that extends from the end of the second inner edge opposite the straight edge to form a second area for receiving the second portion. 
     For yet another aspect of the present invention, a downlight luminaire can include a housing for receiving and holding a lighting module having a light source. The downlight luminaire also can include at least one torsion spring receiver coupled to the housing. Each torsion spring receiver can include, a backstop having a substantially straight edge, a first torsion spring receiver portion disposed on a first side of the backstop and a second torsion spring receiver portion disposed on the first side. The first torsion spring portion can include a first edge that extends at a first acute angle from the straight edge to a first inner hook-shaped edge. The first torsion spring receiver portion can receive a first portion of a torsion spring of the lighting module. The second torsion spring receiver portion can include a second edge that extends at a second acute angle from the straight edge to second inner hook-shaped edge. The second torsion spring receiver portion can receive a second portion of the torsion spring. 
     For yet another aspect of the present invention, a light fixture can include a housing for receiving and holding a lighting module having a light source. At least one torsion spring receiver can be coupled to the housing. Each torsion spring receiver can include a backstop having a substantially straight edge. A first torsion spring receiver portion can be disposed on a first side of the backstop and include a first edge that extends from the straight edge to a first inner hook-shaped edge. The first torsion spring receiver portion can receive a first portion of a torsion spring of the lighting module. A second torsion spring receiver portion can be disposed on the first side and include a second edge that extends from the straight edge to second inner hook-shaped edge. The second torsion spring receiver portion can receive a second portion of the torsion spring. The first hook-shaped edge can be positioned at a greater distance orthogonally from the substantially straight edge than the second hook-shaped edge. 
     These and other aspects, features, and embodiments of the invention will become apparent to a person of ordinary skill in the art upon consideration of the following detailed description of illustrated embodiments exemplifying the best mode for carrying out the invention as presently perceived.

     DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
     Embodiments of the invention are directed to improved installation features for recessed lights, such as downlights. For example, in some embodiments of the invention, the recessed light may include a housing that can be installed in a hollow space of a ceiling, wall, or other structure, and a lighting module having a light source and being removably attachable to the housing. The housing may include one or more improved torsion spring receivers each for accepting and holding a torsion spring coupled to the lighting module. In another embodiment of the present invention, the lighting module may include an improved flexible conduit configuration that allows a flexible conduit connected to the flexible conduit connector to lay flatter in the housing and thereby reduce the amount of plenum space required for the housing installation. In one embodiment, the improved flexible conduit connector is mounted on a surface that is angled in the direction of the flexible conduit. 
     The following description of exemplary embodiments refers to the attached drawings. Any spatial references herein such as, for example, “upper,” “lower,” “above,” “below,” “rear,” “between,” “vertical,” “angular,” “beneath,” etc., are for the purpose of illustration only and do not limit the specific orientation or location of the described structure. 
     Referring now to the figures, in which like numerals represent like (but not necessarily identical) elements throughout the figures, exemplary embodiments of the present invention are described in detail.  FIGS. 1-3  depict portions of an exemplary recessed light  100  having improved installation features, in accordance with certain exemplary embodiments. In particular,  FIG. 1  is a partial perspective view of the recessed light  100 ;  FIG. 2  is a top view of a portion of the recessed light  100 ; and  FIG. 3  is a partial perspective view of the recessed light  100 . 
     Referring now to  FIG. 1 , the exemplary recessed light  100  includes a housing  110  and a lighting module  150  removably attachable to the housing  110 . The housing  110  includes a lamp holder  112  that forms an aperture for receiving the lighting module  150 . The housing  110  also includes mounting brackets  130  attached to either side of the lamp holder  112 . Each mounting brackets  130  is also attached to a frame  115  that can be attached to a support structure (not shown) to hold the housing  110  in place. For example, the housing  110  can be installed in a hollow space within a ceiling by attaching the frames  115  to a ceiling joist support structure. Each mounting bracket  130  also includes at least one torsion spring receiver  140  discussed in further detail in connection with  FIGS. 2 and 3 . In one exemplary embodiment, the housing  110  includes two torsion spring receivers  140  positioned substantially on opposite sides of the lamp holder  112 . 
     The lighting module  150  houses a light source (not shown) and includes at least one reflector  155  that directs or controls light output by the light source. The light source includes one or more lamps, such as one or more light emitting diodes (“LEDs”), compact fluorescent lamps (“CFLs”), incandescent lamps, or high-intensity discharge (“HID”) lamps, or any other light source known to one or ordinary skill in the art. The reflector  155  includes an opening (not shown) at one end and disposed in the direction of illumination. The lighting module  150  also includes an upper surface  157  above the reflector  155  and opposite the direction of illumination. In certain exemplary embodiments, the upper surface  157  is substantially planar. In certain exemplary embodiments, one or more LED&#39;s, LED die packages, or LED chip on board light sources are coupled directly to or directly adjacent to the bottom side of the upper surface  157 . 
     The lighting module  150  also includes a conduit connector  161  and a heat sink  171  disposed on or above the upper surface  157 . In one exemplary embodiment, each of the conduit connector  161  and the heat sink  171  are coupled to the top side of the upper surface  157 . The heat sink  171  dissipates heat generated by the light source. The heat sink  171  is configured and sized accordingly to allow for the conduit connector  161  and for receiving a flexible conduit  165  at a desired angle while keeping the light source at its rated or preferred operating temperature. The heat sink  171  also is sized based on dispersing sufficient amount of heat based on the light source. The heat sink  171  is capable of being fabricated from aluminum or any other suitable material known to one of ordinary skill in the art. In the illustrated embodiment, the heat sink  171  includes a multitude of heat sink fins  172  extending radially from a central core extending up from the upper surface  157 . Other configurations of heat sinks are also feasible without departing from the scope and spirit of the present invention. 
     The conduit connector  161  is disposed between two of the heat sink fins  172  and includes at least one aperture that extends from its top side  162  through to its bottom side inside the lighting module  150 . This aperture provides a pathway for electrical connections from outside the lighting module  150  to access the inner portion of the lighting module  150 . The flexible conduit  165  is removably attachable to the conduit connector  161  and is used to route electrical wires or cables between the lighting module  150  and another device, such as a power source. For example, in an LED light source embodiment, a power cable is routed between one or more LEDs, LED die packages, or LED chip on board modules disposed in the lighting module  150  and an LED driver  199  disposed on or within the housing  110  via the flexible conduit  165 . 
     The conduit connector  161  is mounted on an angled surface  159  that is disposed at an angle with respect to the upper surface  157 . In one embodiment, the angled surface  159  slopes downward in a lateral direction with respect to the upper surface  157 . In one embodiment, the angled surface  159  slopes downward along a tangent to the perimeter of the upper surface  157 . In certain exemplary embodiments, the angled surface  159  also is disposed at an angle with respect to a radial line extending from the center of the upper surface  157  to the perimeter of the upper surface  157 . This angle with respect to the radial line helps route the flexible conduit  165  over the area of the torsion spring  185  and bracket  130 . In one embodiment, the angled surface  159  slopes downward at a 15° angle in the lateral direction and is offset with respect to the radial line at a 13° angle. In certain exemplary embodiments, the angled surface  159  slopes downward at an acute angle (with respect to the upper surface  157 ) in the lateral direction and is offset with respect to the radial line at an acute angle. 
     In certain exemplary embodiments, the angled surface  159  slopes downward in two directions or with respect to two axes. In one example, the angled surface  159  slopes downward from the center of the upper surface  157  towards the perimeter or outer edge of the upper surface  157  and also slopes downward in a lateral direction with respect to the upper surface  157 . In certain exemplary embodiments, the angled surface  159  slopes downward in one or both directions between 3-85 degrees with respect to the upper surface  157 . In certain exemplary embodiments, the angled surface  159  slopes downward in one or both directions at an acute angle with respect to the upper surface  157 . In certain exemplary embodiments, the angled surface  159  slopes downward in one or both directions at an obtuse angle with respect to the upper surface  157 . 
     Although a portion of the angled surface  159  is illustrated as being recessed in the upper surface  157 , other configurations are also feasible. In certain exemplary embodiments, a portion or substantially the entirety of the angled surface  159  is disposed above the upper surface  157 . In one example, the angled surface  159  is disposed on a raised surface, such as a pad, disposed on or above the upper surface  157 . Such a pad may include a substantially cube-shaped component with a surface having the desired angle(s) mounted thereon. 
     In another example, one end of the angled surface  159  extends above the upper surface  157  while an opposite end extends below the upper surface  157 . To extend an end of the angled surface  159  above the upper surface  157 , a wall may extend up from the upper surface  157  to support that end. To extend an end of the angled surface  159  below the upper surface  157 , a wall may extend down from the upper surface  157  into the lighting module  150  to support that end. In one example, one lateral end of the angled surface  159  closer to one heat sink fin  172  extends above the upper surface  157  while an opposite end closer to a second heat sink fin  172  extends below the upper surface  157 . For embodiments in which the angled surface  159  is angled downward in a lateral direction and also angled downward in a radial direction, the end of the angled surface  159  closer to the center of the upper surface  157  extends above the upper surface  157  while the end of the angled surface  159  closer to the perimeter of the upper surface  157  extends below the upper surface  159 . 
     Several advantages are realized by disposing the conduit connector  161  on an angled surface  159  and thereby angling the conduit connector  161 . First, by angling the conduit connector  161  in the direction that the flexible conduit  165  originates or approaches the conduit connector  161 , the flexible conduit  165  can lay flatter than with a vertical conduit connector orientation. As the bend radius of flexible conduit  165  is typically limited, a vertical conduit connector would require the flexible conduit to extend higher above the upper surface  157  than an angled conduit connector  161  allows. For example, some flexible conduits have a bend radius of approximately 1.75 inches or 2.00 inches or larger. The flatter cable lie reduces the plenum space required for installing the recessed light  100 . In addition, the flatter cable lie coupled with the conduit connector  162  being installed on the upper surface  157  rather than above the heat sink  171  allows for the recessed light  100  to be more compact for the recessed light  100  to be installed in shallower areas. This configuration also allows for the flexible conduit  165  to enter the area of the heat sink  171  laterally and below the upper edge of the heat sink  171 . Thus, extra space is not required in the installation area for the flexible conduit  165  to run above the heat sink  171 . 
     Another advantage of the angled conduit connector  161  is that the lighting module  150  is installed and removed with ease as the angle of the conduit connector  161  lends itself to direct the flexible conduit  165  to its ultimate destination when the lighting module  150  is pressed into the housing  110 . As the lighting module  150  is installed in the housing  110 , the angled conduit connector  161  guides the flexible conduit  165  into a lateral orientation without twisting or bending the flexible conduit in an unwanted direction. 
     Turning now to  FIGS. 2-4 , each torsion spring receiver  140  is the attachment point between the housing  110  and a respective torsion spring  180  of the lighting module  150 . Each torsion springs  180  is attached to the reflector  155  or other exterior portion of the lighting module  150  by way of a torsion spring bracket  181 . The exemplary torsion springs  180  include several coils  182 , a first shaft  183  extending from the coils  182  and having a first end  184 , and a second shaft  185  extending from the coils  182  and having a second end  186 . In general, a user can install the lighting module  150  in the housing  110  by squeezing the two ends  184 ,  186  of each torsion spring  180  together and inserting the ends  184 ,  186  into an open area  149  of the respective torsion spring receiver  140 . By squeezing the two ends  184 ,  186  together, the coils  182  are twisted tighter resulting in a force that attempts to cause the ends  184 ,  186  to retract. With the shafts  183 ,  185  inserted into the open area  149 , the user can push the lighting module  150  into the housing  110  and release the ends  184 ,  186 . The force of the coils  182  causes the shafts  183 ,  185  to retract and thus, causes the shafts  183 ,  185  to engage hook-shaped slots  138 ,  148 , respectively, of the torsion spring receiver  140 . The torsion spring receivers  140  and the torsion springs  180  are configured so that the torsion springs  180  pulls the lighting module  150  into the housing  110  as discussed in further detail below. 
     The exemplary torsion spring receivers  140  include several features that improve the installation and removal of the lighting module  150  from the housing  110 . As best seen in  FIG. 2 , the torsion spring receiver  140  includes a backstop  131  and two torsion spring receiver portions  133 ,  143 . In certain exemplary embodiments, the backstop  131  and torsion spring receiver portions  133 ,  143  are fabricated as a single, integrated unit. In certain alternative embodiments, the torsion spring receiver  140  includes a first bracket having the first torsion spring receiver portion  133  and a second bracket having the second torsion spring receiver portion  143 . In such an embodiment, the two brackets are coupled to the backstop  131  at opposite lateral sides. 
     The open area  149  is defined by an inner surface of the backstop  131  and inner edges of the torsion spring receiver portions  133 ,  143 . In particular, the backstop  131  includes a substantially planar surface that provides a substantially straight edge  132  for the open area  149 . The first torsion spring receiver portion  133  includes an edge  134  that extends from the edge  132  to a semicircle-shaped edge  135 . The first torsion spring receiver portion  133  also includes a retaining tab  137  having a substantially straight edge  136  extending from the semicircle-shaped edge  135  opposite the edge  134 . The edges  133 - 136  form the hook-shaped slot  138  for receiving and holding in place a portion of the torsion spring  180 . 
     The edge  134  extends out orthogonally from the edge  132  and then curves to extend at an acute angle with respect to the edge  132 . This angled configuration enables the edge  134  to guide the shaft  183  into the hook-shaped slot  138  during installation of the lighting module  150  with the housing  110 . That is, when the shaft  183  is inserted into the open area  149  and the ends  184 ,  186  are released, the tension of the coils  182  causes the shaft  183  to press against the edge  134 . As the shaft  183  presses against the edge  134 , the edge  134  guides the shaft  183  into the hook-shaped slot  138 . In certain exemplary embodiments, rather than extending out orthogonally, the edge  134  extends at the angle directly from the edge  132 . 
     The second torsion spring receiver portion  143  includes an edge  144  that extends from the straight edge  132  to a semicircle-shaped edge  146 . The second torsion spring receiver portion  143  also includes a retaining tab  147  having a substantially straight edge  146  extending from the semicircle-shaped edge  145  opposite the edge  144 . The edges  143 - 146  form the hook-shaped slot  148  for receiving and holding in place a portion of the torsion spring  180 . 
     The edge  144  extends out orthogonally from the edge  132  and then curves to extend at an acute angle with respect to the edge  132 . This angled configuration enables the edge  144  to guide the shaft  185  into the hook-shaped slot  148  during installation of the lighting module  150  with the housing  110 . That is, when the shaft  185  is inserted into the open area  149  and the ends  184 ,  186  are released, the tension of the coils  182  causes the shaft  185  to press against the edge  144 . As the shaft  185  presses against the edge  144 , the edge  144  guides the shaft  185  into the hook-shaped slot  148 . In certain exemplary embodiments, rather than extending out orthogonally, the edge  144  extends at the angle directly from the edge  132 . By having the edges  134 ,  144  angled with respect to the edge  132  as illustrated, the size of the open area  149  is increased. This larger open area  149  makes it easier for a user to insert the ends  184 ,  186  into the open area  149 . 
     The retaining tabs  137 ,  147  and the edges  136 ,  146  also are positioned at an angle with respect to the straight edge  132  of the backstop  131 . In particular, the retaining tabs  137 ,  147  are configured to point in towards the open area  149 . In this configuration, the edges  136 ,  146  help prevent the force exerted on the shafts  183 ,  185  by the coils  182  from causing the torsion spring  180  to slip from the torsion spring receiver  140 . If the retaining tabs  137 ,  147  extended in a direction substantially in parallel with the straight edge  132 , the force exerted on the shafts  183 ,  185  by the coils  182  could more easily cause the torsion spring  180  to slip from the torsion spring receiver  140  as parallel edges would provide less resistance to this force. In certain exemplary embodiments, the retaining tabs  137 ,  147  and the edges  136 ,  146  are angled at an acute angle with respect to the edge  132 . 
     In certain exemplary embodiments, the retaining tabs  137 ,  147  are configured to match or resemble the profile of the heat sink  171 . That is, in certain exemplary embodiments, the retaining tabs  137 ,  147  are tangential to the circumference or perimeter of the heat sink  171 . This configuration helps prevent the heat sink  171  from contacting or hitting the torsion spring receiver  140  during installation of the lighting module  150  with the housing  110 . This configuration also supports a more compact design of the housing  110 . 
     In certain exemplary embodiments, the torsion spring receiver  140  does not include the straight edge  132 . Rather, an end of the edge  134  opposite the semicircle-shaped edge  135  contacts an end of the edge  144  opposite the semicircle-shaped edge  145  to form a v-shape. 
     In certain exemplary embodiments, the torsion spring receiver  140  is configured to facilitate the offset of the torsion spring  180 . As best seen in  FIG. 4 , the shafts  183 ,  185  of the torsion spring  180  have an offset caused by the coils  182 . In one exemplary embodiment, the offset between inner edges of the shafts  183 ,  185  is approximately 0.07 inches and the offset between outer edges of the shafts  183 ,  185  is approximately 0.19 inches. The offset of the torsion spring  180  can vary based on the number of coils  182 , the diameter of the coils  182 , and the thickness of the rod or wire used to form the torsion spring  180 . One way of facilitating this offset includes widening the opening of one or both hook-shaped slots  138 ,  148 . Another way to facilitate the offset includes offsetting the hook-shaped slots  138 ,  148  to match the offset of the torsion spring  180 . In certain exemplary embodiments, one of the hook-shaped slots  136 ,  146  is disposed at a greater orthogonal distance from the backstop  131  than the other hook-shaped slot  138 ,  148  to compensate for the offset. For example, one of the edges  134 ,  144  can extend further from the straight edge  132  or at a different angle than the other edge  134 ,  144  to position the respective hook-shaped slot  138 ,  148  at a greater orthogonal distance from the straight edge  132  than the other hook-shaped slot  138 ,  148 . 
       FIG. 5  is a side view of the lighting module  150  detached from the housing  110  and  FIG. 6  is a side view of the lighting module  150  installed in the housing  110 . Referring to  FIGS. 1-6 , a user can install the lighting module  150  in the housing  110  by holding the lighting module  150  proximal to the housing  110  and making the appropriate electrical connections. For example, the user may connect power supply wires (routed via the conduit  165 ) from a driver  199  to the light source. The user may route the wires through the aperture in the conduit connector  161  and make the appropriate connection to the light source. The user may attach the conduit  165  to the conduit connector  161 . 
     With the electrical connections made, the user squeezes the ends  184 ,  186  of the torsion springs  180  together and inserts the ends  184 ,  186  into the open area  149  of the respective torsion spring receiver  180 . The user can push the lighting module  150  into the housing  110  and release the ends  184 ,  186  into the respective torsion spring receiver  140 . After being released, the tension in the coil  182  of each torsion spring  140  causes the respective shaft  183  to press against the respective edge  134  and the edge  134  guides the shaft  183  into the hook-shaped slot  138 . Similarly, the respective shaft  185  presses against the respective edge  144  and the edge  144  routes the shaft  185  into the hook slot  148 . The retaining tabs  137 ,  147  prevent the respective shafts  183 ,  185  from slipping from the respective hook-shaped slots  136 ,  146 . 
     While the torsion spring shafts  183 ,  185  are routed into position in the torsion spring receiver  140 , the span of the torsion spring  180  pulls the lighting module  150  into the proper position in the housing  110 . That is, as the shafts  183 ,  185  retract and press against the edges  134 ,  144 , the torsion spring  180  pulls the lighting module  150  upwards (for a downlight) into the housing  110 . The size of the opening  149  and thus, the distance between hook-shaped slots  136 ,  146 , is configured along with the torsion spring  140  such that the torsion spring  140  pulls the lighting module  150  into the proper position within the housing  110  without releasing the torsion spring  180  from the torsion spring receiver  140 .
