Description




TECHNICAL FIELD




This invention relates to recessed lighting fixtures.




BACKGROUND




A typical recessed lighting fixture includes a frame, a reflector, a junction box and structure for attaching the frame to the ceiling. The frame includes an opening through which the reflector is inserted to direct light to an area below the lighting fixture. The reflector may be, for example, a wall-wash reflector or a down-wash reflector.




The wall-wash reflector directs the light down at an angle away from the lighting fixture. The down-wash reflector directs the light down from the lighting fixture. Different mechanisms can be used to retain the reflector in the frame. For example, the reflector may have an opening with a circumference that is larger than the opening in the frame. In such a configuration, the reflector sits on the top surface of the frame and surrounds the opening.




The junction box is an enclosure mounted on the frame that functions as a receptacle for joining the wires from an electrical power source and a lamp socket in the reflector. The junction box has walls with pry-out plates to receive the wires. The frame may be mounted to the ceiling using known techniques. For example, the frame may include a barbed insert that can be nailed into a wooden beam in the ceiling.




SUMMARY




In one general aspect, a recessed lighting fixture includes a frame and a reflector. The frame includes an aperture and at least one mount. The reflector includes at least one torsion spring configured to be received in the mount when the reflector is mounted to the frame.




The recessed lighting fixture may include one or more of the following features. For example, the recessed lighting fixture may include a metal band having a first end mounted to the reflector and a second end mounted to the torsion spring. The torsion spring may have a pair of opposing arms, the mount may include a slotted channel, and mounting the reflector to the frame may include inserting the opposing arms into the slotted channel.




The frame may include two mounts and the reflector may include two torsion springs. The two mounts may be separated around a circumference of the aperture in a first direction that differs from a distance in a second direction (i.e., by an angle of other than 180°). The two torsion springs may be separated in the same way. The first distance may define an angle of approximately 140° to 160° or, more particularly, the first distance may define an angle of approximately 150°.




The aperture may have a noncircular opening. The aperture may include one or more (e.g., four) lobes. The aperture may be further configured to receive an ellipsoidal reflector or a round reflector.




The recessed lighting fixture may include a lip that protrudes perpendicularly below the aperture and encircles the circumference of the aperture. The frame of the recessed lighting fixture may further include a pair of hanger bar mounts and a pair of hanger bar brackets slidably attached to the hanger bar mounts. Each hanger bar mount may include a slot and each hanger bar bracket may include at least one tab configured to slide in the slot. Each hanger bar bracket may further include a threaded channel. Attaching the hanger bar bracket to the hanger bar mount may include passing a threaded screw through the slot and threading the screw in the threaded channel.




Each hanger bar mount may include at least one tab configured to limit vertical movement of the attached hanger bar bracket. The hanger bar brackets may have a round wall configured to be flush with a round mounting conduit and a horizontal wall configured to be flush with an L-shaped hanger bar. The hanger bar mount may include a first series of openings on a first side of the slot and a second series of openings on a second side of the slot. The first series of openings may be vertically offset from the second series of openings.




The recessed lighting fixture may further include a junction box that includes a plate having at least one edge having a slot cut into the edge. The junction box may also include a retaining spring mounted on the plate and having a retaining portion and an outer edge. The retaining portion may extend into the slot such that the outer edge is substantially flush with the edge of the plate. The retaining portion may be a bend of the retaining spring that extends through the slot in the plate.




In another general aspect, a recessed lighting fixture includes a frame and a reflector. The frame includes an aperture and a pair of mounts separated around a circumference of the aperture in a first direction that differs from a distance in a second direction (i.e., by an angle of other than 180°). The reflector includes a pair of torsion springs separated around a circumference of the reflector in the same way. The reflector is configured to be received in the mount when the reflector is mounted to the frame. The aperture may be a noncircular opening.




In another general aspect, a lighting fixture is installed by providing a frame including an aperture and at least one mount, providing a reflector including at least one torsion spring configured to be received in the mount when the reflector is mounted to the frame, and mounting the reflector to the frame.




Embodiments may include one or more of the following features. For example, the torsion spring may include a pair of opposing arms, the mount may include a slotted channel, and mounting the reflector to the frame may include inserting the opposing arms into the slotted channel. The frame may include two mounts that are separated around a circumference of the aperture in a first direction that differs from a distance in a second direction, and the torsion springs may be separated in the same way.




The frame may be mounted to a hanger bar. In particular, the frame may include a pair of hanger bar mounts and a pair of hanger bar brackets slidably attached to the hanger bar mounts to define a mounting volume configured to receive the hanger bar when the frame is mounted to the hanger bar. Each hanger bar mount may include a slot and each hanger bar bracket may include at least one tab configured to slide in the slot. Attaching the hanger bar brackets to the hanger bar mounts may include inserting the tabs in the slots. Each hanger bar bracket may further include a threaded channel, and attaching the hanger bar bracket to the hanger bar mount may further include passing a threaded screw through the slot and threading the screw into the threaded channel.




In another general aspect, a junction box includes a retaining spring and a plate having at least one edge having a slot cut into the edge. The retaining spring is mounted on the plate and includes a retaining portion and an outer edge. The retaining portion extends into the slot and the outer edge is substantially flush with the edge of the plate.




The recessed lighting fixture provides numerous advantages. For example, the same frame can be used for at least three lamps types: incandescent, metal halide, and fluorescent. The noncircular aperture in the frame will accept existing or new finishing sections. Torsion springs mounted on the reflector eliminate cumbersome fasteners and provide for easy installation of the reflector in the frame. The torsion springs and their mounts on the frame are keyed at the same angle, such as 150°, to ensure against mis-installation of the reflector in the frame. A junction box spring is recessed over the junction box, rather than protruding beyond the junction box, so that the junction box spring can accommodate a variety of ballasts and transformers mounted to the junction box.




The recessed lighting fixture also includes a mounting system that provides numerous benefits to the installer. For example, the hanger bar brackets are attached to the hanger bar mounts such that they are self-aligning and self-centering. Each hanger bar mount includes a stop in a predetermined position so that a hanger bar bracket can be assembled at the factory with the bracket against the stop. With the bracket against the stop, a hanger bar or mounting conduit can be installed in the recessed lighting fixture without adjusting the mounting position of the hanger bar bracket. If the vertical position of the frame must be adjusted, the hanger bar bracket can be vertically adjusted while viewing its position through openings in the hanger bar mounts. In this manner, the position of the frame relative to both hanger bar brackets can be set so that they are at the same height. The openings may be configured such that two columns of openings are vertically offset to permit finer control of the positioning. The shape of the hanger bar brackets allows use of round mounting conduits and mounting bars, as well as L-shaped bars.











Other features and advantages will be apparent from the following description, including the drawings, and from the claims.

DETAILED DESCRIPTION




Referring to

FIGS. 1-3

, a recessed lighting fixture


100


includes a universal frame


105


that has a junction box


107


with a junction box spring


108


. The fixture


100


also includes a pair of hanger bar mounts


110


to which a pair of hanger bar brackets


115


are slidably attached by screws


116


passing through slots


117


in the mounts


110


. An L-shaped hanger bar


118


is slidably installed between each hanger bar mount


110


and the corresponding hanger bar bracket


115


.




The position of the hanger bar mounts


110


relative to the hanger bar brackets


115


can be adjusted to adjust the height of the recessed lighting fixture in the ceiling. A series of holes


119


on opposite sides of the slots


117


are used to provide a scale for ensuring that the hanger bar brackets


115


are at the same relative position on the hanger bar mounts. The spacing between holes


119


on opposite sides of the slots


117


can be made such that opposite holes


119


are at the same height or are offset at slightly different heights. For example, opposite holes can be offset by one hole diameter. Using such a hole spacing provides more exact positioning of opposite brackets


115


by permitting the position of each bracket to be adjusted to within a hole diameter.




A reflector


120


is installed in the frame


105


through an aperture


125


, which has a lip


127


that protrudes perpendicularly below the aperture and encircles the circumference of the aperture


125


. The reflector


120


includes a socket


130


, a trim body


135


, and an upper ring


140


. The upper ring


140


includes a pair of rivets


145


that attach a pair of metal bands


150


to the upper ring


140


. Each metal band


150


includes a torsion spring


155


having opposing arms


160


.




The reflector


120


is retained in the frame


105


by the interaction of the torsion spring arms


160


with a pair of mounting ears


165


, each of which has a slotted channel


170


. First, the reflector


120


is inserted into the aperture


125


such that the trim body


135


rests against the lip


127


. The opposing arms


160


then are inserted into the slotted channel


170


by pulling the arms together and releasing them when they are in the slotted channel. The opposing arms


160


are kept together in the slotted channel


170


, although the torsion spring


150


resists placing the arms in such proximity. The resistance to being kept together, which tends to cause the arms


160


to move apart, pulls the reflector


120


into the aperture until the trim body


135


rests against the lip


127


. Retaining the reflector in this manner causes the trim body


135


to be flush with the ceiling in which the recessed lighting fixture is installed. The mounting ears


165


and the torsion springs


155


are keyed apart at the same angle, such as 150°, to eliminate mis-installation of the trim body


135


.




Referring also to

FIGS. 4-6

, the aperture


125


has four or more lobes


172


that cause the aperture to be noncircular. Each lobe


172


is separated from the adjacent lobe


172


by a portion


173


that protrudes into the aperture


125


. The noncircular aperture


125


and the frame


105


simulate existing die cast frames with the indented details on those frames. The aperture


125


accepts existing or new finishing sections. For example, the aperture can accept round or elliptical reflectors.




Referring to

FIG. 7

, the socket


130


includes a pair of vertically slotted channels


175


, each of which opens to a pair of offset, horizontally slotted channels


180


. During installation, the socket


130


is placed around the upper ring


140


, the vertical slotted channels


175


are passed over the rivets


145


, and the socket is turned clockwise to entrap the rivets


145


in the horizontally slotted channels


180


. The horizontally slotted channels


180


are offset so that the socket height can be adjusted relative to the reflector


120


, for example, to accommodate different types of lighting, such as incandescent, fluorescent, and metal halide bulbs. A conduit


185


contains wires that supply electrical power to the socket


130


and the bulb (not shown).




Referring to

FIGS. 8-10

, the hanger bar mounts


110


and the hanger bar brackets


115


are used to mount the recessed lighting fixture


100


to the hanger bars


118


or to a mounting conduit (not shown) recessed in a ceiling. Each hanger bar bracket


115


includes an upper vertical plate


200


that includes a threaded channel


205


through which the screw


116


(

FIG. 1

) is threadably attached to hold the bracket


115


to the hanger bar mount


110


. When the bracket


115


is mounted to the hanger bar mount


110


, the upper plate


200


is parallel to and flush with the hanger bar mount


110


.




Each bracket


115


also includes an upper horizontal plate


210


and a parallel, lower horizontal plate


215


. Two L-shaped tabs


220


extend from the upper horizontal plate


210


and two L-shaped tabs


225


extend from the lower horizontal plate


215


. Each pair of tabs


220


,


225


forms an opening


230


that is partly enclosed on two sides by the L-shaped tabs. An alignment tab


235


extends from a lower vertical plate


240


and is inserted into slot


117


of the hanger bar mount


110


when the bracket


115


is mounted on the hanger bar mount. Like upper vertical plate


200


, the lower vertical plate


240


is parallel to and flush with the hanger bar mount


110


when the bracket is mounted to the mount.




To mount a hanger bar


115


bracket to a mount


110


, the bracket is passed over the mount


110


through the opening


230


in the bracket, such that the tabs


220


,


225


are on one side of the mount and the vertical plates


200


,


240


are on the other side of the mount. The interaction between the alignment tabs


235


and the slots


117


, and between the tabs


220


and


225


and the mounts keeps the brackets aligned and self-centered with the mount, and prevents the bracket from moving away from the mount.




Referring also to

FIGS. 11-15

, each hanger bar bracket


115


also includes a shaped wall


245


that is shaped to permit the use of different configurations of hanging bars and mounting conduits within the bracket


115


when it is mounted to the mount


110


. For example, the shaped wall


245


includes a rounded section


250


that permits the recessed lighting fixture


100


to be mounted in the ceiling using a round conduit


255


(FIGS.


11


and


12


). The relatively longer length of upper horizontal plate


210


, compared to the length of lower horizontal plate


215


, is such that the L-shaped hanger bar


118


fits securely within the bracket


115


without excessive play (FIGS.


13


-


15


). A pair of tabs


257


extend from each hanger bar mount


110


and limit upward movement of the hanger bar bracket


115


by acting as a stop for the upper vertical plate


200


. When the hanger bar brackets are mounted to the mounts during manufacturing, the brackets can be set in position against the stops. With this positioning, the frame can be mounted in the ceiling without the installer needing to adjust the brackets.




The hanger bar


118


includes mounting holes


260


passing through a vertical section


265


, a pair of indentions


270


, and a horizontal edge


275


. The hanger bar


118


can be bent at the indentions


270


to provide a more secure mounting to a T-bar (not shown).




Referring to

FIGS. 16 and 17

, the junction box spring


108


is recessed over the junction box rather than extending beyond the junction box. This permits the junction box


107


to accommodate a variety of ballasts and transformers. For example,

FIG. 16

illustrates a ballast


280


for fluorescent lighting that is mounted on a plate


285


by threadably attaching tabs


290


to the plate using screws


295


.




The junction box spring


108


retains the plate


285


on the junction box


107


by clipping a bend


296


of the junction box spring over the edge of the plate. The bend


296


extends downward through a slot


297


in the top of the junction box. Two protrusions


298


on the frame


105


limit the outward movement of the bottom of the plate


285


. One or more similar protrusions on the other side of the plate


285


limit the inward movement of the bottom of the plate. The combination of the protrusions


298


and the bend


296


retain the plate


285


against the junction box. Pry-out plates


300


are removable to insert wiring into the junction box to provide power to the ballast.





FIG. 17

illustrates a ballast


305


for high intensity discharge lighting mounted on a plate


285


by flexibly attaching tabs


310


to the plate using a screw


315


. The plate


285


is retained on the junction box


107


by clipping it under the junction box spring


108


. A transformer also can be mounted on the plate


285


and power can be provided through the transformer to step down the voltage from, for example, 277 volts to 120 volts.




Referring to

FIGS. 18 and 19

, the recessed light fixture


100


includes a reflector


400


mounted through the noncircular aperture


125


and the ballast


305


mounted on the junction box


107


. The reflector


400


includes an opening


405


configured to receive a horizontal socket housing


410


. The horizontal socket housing


410


includes an upper wall


415


, a pair of side walls


420


, a rear wall


425


, a bottom wall


430


, and an opening


435


. The opening


435


mates with the reflector's opening


405


when the horizontal socket housing


410


is mounted on the reflector


400


. To mount the socket housing


410


on the reflector


400


, the socket housing opening


435


is placed adjacent to the opening


405


, such that a pair of wall extensions, each having a tab


440


, are securely positioned adjacent to a pair of vertical walls


445


defining opposite sides of the opening


405


. A spring tongue


450


, which is mounted on the socket housing


410


by a rivet


455


, fits within a rectangular groove


460


on the top of the reflector


400


. A positive spring retention system assembly also can be used to mount the socket housing on the reflector. The socket housing


410


includes an opening


465


through which wires


470


pass to provide electrical power to a lamp socket (not shown) that is positioned within the socket housing


410


. The socket housing also includes openings


475


through the upper wall


415


to provide a vent for heat generated by an energized lamp in the lamp socket.





FIGS. 20-22

illustrate the installation of an L-shaped plate


485


in the socket housing


410


. The electrical wires


470


pass through an opening


490


in a first segment


495


of the L-shaped plate


485


, and out of the socket housing


410


through the opening


465


. The L-shaped plate


485


is rotated such that the first segment


495


is placed adjacent to the side wall


420


, which includes opening


465


, with the opening


490


positioned adjacent to the opening


465


. A bracket tab


500


, extending from a second segment


505


of the L-shaped plate


485


, then is inserted into a slot


510


to keep the plate securely positioned within the housing


410


. A cable connector


515


is inserted through the openings


465


and


490


, and clips into place, to keep the plate positioned within and mounted to the housing. The connector also may be twisted or screwed into place, or may be keyed with slots in the openings


465


and


490


.




Referring to

FIGS. 23-25

, the L-shaped plate


485


includes a socket


520


into which a lamp may be inserted. One, two or three sockets


520


may be mounted on the L-shaped plate


485


. The L-shaped plate


485


includes five upper pairs of holes


525


and five lower pairs of holes


530


. The upper pairs of holes


525


are horizontally offset from the lower pairs of holes


530


and vertically separated by the slots


535


. When one or more sockets


520


are mounted on the plate


485


, the wires


470


pass through the slots


535


.




To mount one socket on the plate


485


(FIG.


23


), pins (not shown) extending from the back of the socket


520


are inserted into the middle pair of holes


525


,


530


. The pins may be retained in the holes


525


,


530


by an interference fit, press fit or other mechanism. To mount two sockets


520


on the plate


485


(FIG.


24


), pins extending from the back of the sockets are inserted into pairs of holes


525


,


530


adjacent to the pair of middle holes


525


,


530


. To mount three sockets


520


to the plate


485


(FIG.


25


), pins extending from the back of one socket


520


are inserted into the middle pair of holes


525


,


530


, and pins extending from the two adjacent sockets


520


are inserted into the pairs of holes


525


,


530


on the ends. The holes into which the pins are inserted when two sockets


520


are used are left unused when three sockets


520


are used. The pairs of holes


525


,


530


can be modified to be single holes or more than two holes, depending on the configuration of the socket. When lamps (not shown) are inserted into the sockets


520


, and the socket housing


410


is mounted to the reflector


400


, the lamps extend horizontally from the socket housing into the reflector.

FIGS. 26-29

, the reflector system


600


, similarly to the reflector


120


of

FIG. 1

, may include metal bands


150


to which torsion spring arms


160


are attached. The reflector


600


may be mounted on the frame


105


with the torsion spring arms


160


mounted on the mounting ears


165


.




Referring to

FIGS. 30-32

, a down-wash reflector system


700


may be used with the recessed lighting fixture


100


. The down-wash reflector system


700


includes an upper elliptical parabolic reflector


705


and a lower non-imaging parabolic reflector


710


. A lens


712


is kept captive in the upper reflector


705


. The upper reflector


705


includes an opening


715


into which the socket spring


630


is inserted. The opening


715


includes a circular portion


720


and a pair of slotted portions


725


. To mount the socket spring


630


, the arms


640


are pressed inward and the lamp


660


is inserted into the circular portion


720


of the opening


715


while at the same time the arms


640


are inserted into the slotted portions


725


of the opening


715


. When the bends


650


are adjacent to the edges


730


of the slotted portions


725


, the arms


640


are released such that the bends


650


press outwardly against the edges


730


. The outward force of the arms


640


against the edges retains the socket spring


630


in the upper reflector


705


. Like the wall-wash reflector system


600


, the down-wash reflector system


700


can be mounted to the frame


105


with the metal bands


150


attached to the reflector system


700


and the attached torsion spring arms


160


mounted to the mounting ears


165


.




The socket spring


630


can be modified to include additional pairs of bends to make the spring more universally applicable. For example, to use a longer lamp, the arms


640


may be longer and may include at least one pair of bends positioned beyond bends


650


so that the base


635


is further away from the reflector. The arms also may include bends spaced at relatively short intervals along their length so that the spring


630


can accommodate various bulbs and reflector systems.




The wall-wash reflector system


600


and the down-wash reflector system


700


can be mounted on the same frame


800


and can be enclosed by the same housing


805


. The frame


800


may have many of the features of the recessed lighting fixture


100


described above. For example, to mount the frame in the ceiling, the frame


800


may include the hanger bar mounts and hanger bar brackets described above. The reflector system


700


or


800


may be mounted to the frame


800


using the torsion spring system described above. The frame


800


also may have the noncircular aperture described above.




Other embodiments are within the scope of the following claims.
