The invention relates to lighting fixtures, and in particular, recessed lighting fixtures for inclined ceilings.
Recessed light fixtures are known for “sloped ceilings” such as cathedral ceilings having an inclined, or sloped ceiling or inclined wall. Typically, the angle of the inclined wall can be indicated as a degree of incline or a pitch. The pitch is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally. For example, a wall that rises 6 inches for every 12 inches of horizontal run has a 6-in-12 pitch (also 6/12 pitch). The sloped wall fixture is designed to work in walls within a range of pitches, for example from 3/12 pitch (14 degrees) to 12/12 (45 degrees).
It is often desirable to install recessed lighting fixtures in inclined ceilings, however known lighting fixtures suitable for inclined ceilings are often not suitable for, or have degraded optical performance, or installation difficulties for a desired range of inclined ceilings.
What is desired then is a recessed light fixture which is suitable for a range of inclined ceilings and which provide improved optical qualities and ease of installation.
What is desired then is a recessed light fixture which is suitable for a range of inclined ceilings and which provide improved optical qualities and ease of installation.
In an embodiment, the light fixture includes an enclosure having a bottom wall with an aperture, a lighting assembly disposed within the enclosure and including a lighting element pivotal relative to the enclosure about a pivot axis which is horizontal when the enclosure is mounted to the support structure. The lighting assembly is pivotal relative to the enclosure about the pivot axis through a first range of relative angles of at least 15 degrees, from a first relative angle to a second relative angle greater than the first relative angle such that the optical axis can be aligned vertically for a first range of inclinations of the inclined ceiling panel comprising the first range of relative angles.
The light fixture includes first and second trim element adapted for use with first and second ranges of inclinations which are configured to mount in the aperture from a room-facing side of the enclosure.
The light fixture includes an angle indicator visible through the aperture from the room-facing side of the enclosure and adapted to indicate a proper relative angle of the lighting assembly relative to the enclosure for vertical alignment of an optical axis of the lighting assembly for a plurality of inclinations of the enclosure in the first range of inclinations.
The light fixture includes a trim indicator visible through the aperture to indicate whether the first or second trim element is suitable for use in a particular inclination.
The lighting assembly includes a bubble level fixed thereto and visible through the aperture, and the bubble level is adapted to indicate when the optical axis is aligned in a predetermined orientation.

The recessed light fixture 10 has an enclosure 12 with an aperture 14 and has a lighting element 16 disposed within the enclosure, such as an LED lighting element, which is operable to emit light through the aperture 14 and into the room. The light fixture 10 is adapted to be mounted within the ceiling or wall structure that is above a ceiling or wall panel 18, adjacent to an interior surface 20 of the ceiling/wall panel 18 and is adapted to be secured and fixed relative to support structure, such as joists (not shown), within the ceiling/wall construction. The aperture 14 is aligned with an opening 22 in the ceiling/wall panel 18. Typically, the enclosure 12 is mounted to support structure prior to installation of the ceiling/wall panel 18, or from above the ceiling/wall panel (i.e., from a side opposite the room-facing side of the ceiling/wall), if installed after the ceiling/wall is constructed.
The lighting element 16 can be fixed to a lighting assembly 24 including a heat sink 28 thermally coupled to the lighting element 16. The lighting assembly 24 can also include a reflector 26 fixed thereto and disposed around the lighting element 16 such that it is configured to reflect light emitted by the lighting element 16 through the aperture 14 and into the room. The reflector 26 can include an open bottom 30 through which light exits the lighting assembly, where the bottom 30 is defined by a circumferential peripheral edge or flange 31 which can lie on a plane, and that plane can be perpendicular to an optical axis 32 of the light assembly 24. Preferably, the reflector 26 and/or bottom 30 thereof are symmetrical about the optical axis 32 and the optical axis 32 passes through a center of the bottom of the reflector.
The enclosure 12 preferably includes a substantially planar bottom wall 34 which, when the light fixture 10 is installed, is closely adjacent to and substantially parallel to the interior surface 20 of the ceiling/wall panel 18. A collar 36 extends downwardly from the bottom wall 34 of the enclosure 12, preferably perpendicularly to the bottom wall 34, and surrounds the aperture 14. When the light fixture 10 is installed, the collar 36 preferably extends into the opening 22 of the ceiling/wall 18 and is sized and shaped complementary to the opening 22 such that the collar 34 follows the contours of the opening 22 and such that a small gap 38 (e.g., ¼-½ inch) exists between an interior of the opening 22 and an exterior of the collar 36. Further, preferably the cut forming the opening 22 in the ceiling/wall 18 is made perpendicular to the plane of the ceiling/wall panel 18 to correspond to the configuration of the collar 36 and so that the opening 22 closely circumscribes the collar 36 (leaving a small gap there between). The opening 22 in the ceiling/wall 18 can be any shape. Typical shapes for the opening are round and square, but other shapes are possible. Thus, the shape of the collar 36 can be round or square, or other shapes.
In a sloped ceiling/wall 18, the support structure (e.g., joists) to which such recessed light fixtures are typically connected are themselves inclined at the same angle as the ceiling/wall panel 18 and the light fixture 10 is mounted with the bottom wall 34 of the enclosure 12 closely adjacent and parallel to the ceiling/wall panel 18 (e.g., closely adjacent and parallel to the interior surface 20 of the ceiling/wall panel 18). Thus, when installed, the recessed light fixture 10 is inclined at the same or similar angle as the ceiling/wall. However, it is often desirable to adjust the angle of the optical axis 32 of the light assembly 24 such that the optical axis 32 is vertical, or at another desired orientation/angle different than that of the ceiling/wall 18 and/or light fixture 10.
The light fixture 10 has mutually orthogonal X, Y and Z axes (See
To compensate for the angled orientation of the installed light fixture 10, the light assembly 24 is operable to pivot relative to the housing or enclosure 12 about the Z axis (e.g., pivot 90). Preferably the light assembly 24 can pivot relative to the enclosure 12, about the Z axis, within a range of angles, from a minimum angle of, for example, 14 degrees (See
The bottom wall 34 of the enclosure 12 can include an uphill end 54 and a downhill end 56 along the longitudinal X axis, where the uphill end 54 is vertically higher than the downhill end 56 when the light fixture 10 is installed. The light assembly 24 is preferably disposed primarily above an uphill half of the aperture 14 (i.e., a half closest to the uphill end 54 of the bottom wall 34 of the enclosure 12). The Z axis preferably passes through the reflector 26 of the light assembly 24, and the Z axis preferably displaced longitudinally (parallel to the X axis) from the optical axis 32 toward the uphill end 54.
A selectively engagable locking mechanism 35 (e.g., a locking lever) is operable to lock the light assembly 24 in a vertical (or other desired) orientation relative to enclosure 12. The locking mechanism 35 is accessible through the aperture 14, from within the room. Thus, when the recessed light fixture 10 is installed in the inclined ceiling/wall 18, the light assembly 24 can be aligned vertically or substantially vertically (or at another angle), and locked in place, such that the optical axis 32 of the light assembly 24 is vertical and light emitted from the light fixture 10 shines straight down.
The light fixture 10 includes trim elements having various configurations adapted for different ranges of incline of the enclosure 12 when installed. For example, the light fixture 10 can include a low-incline trim element 40 (See
Each trim element 40, 140 is adapted to selectively, removably mount to the collar 36 and/or the bottom wall 34 of the enclosure 12 (or other structure of the enclosure 12) such that the trim element is fixed relative to the enclosure 12 when mounted. The trim element 40, 140 is adapted to provide a light pathway for light to travel from the lighting element 14 to the room and to provide a finished appearance to the light fixture installation. When mounted, each trim element 40, 140 preferably extends from an interior (i.e., room-facing side) of the ceiling/wall panel 18, through the opening 22 and the aperture 14 and into an interior of the enclosure 12. The trim element 40, 140 can have an relatively large open bottom 42, 142 surrounded by a radially-outwardly extending, preferably opaque peripheral flange 44, 144 which is parallel to, and contacts an exterior surface 46 of the ceiling/wall panel 18 (i.e., the room-facing surface) and which extends over and covers the gap 38 between the opening 22 in the ceiling/wall and the collar 36 of the light fixture.
The trim element 40, 140 can have an upper portion 46, 146 with a relatively smaller opening covered by a light-transmitting optical element 48, 148 fixed thereto such as a lens and/or diffuser (e.g., a solite lens). The optical element 48, 148, and/or a top surface 50, 150 thereof, is preferably substantially planar and is preferably spaced from, and aligned at an acute angle relative to, a plane defined by the peripheral flange 44, 144 of the trim element 40, 140 (and relative to the ceiling/wall panel 18 when installed). A preferably opaque peripheral wall 52, 152 connects the bottom 42, 142 of the trim element to the upper portion 46, 146 thereof. When the trim element 40, 140 is installed, the optical element 48, 148 is disposed adjacent a bottom portion of the lighting assembly 24, such as the bottom 30 of a reflector 26. The optical element 48, 148 preferably has a sized and shape substantially the same as and/or corresponding to the size and shape of the bottom 30 of the reflector 26 of the light assembly 24 such that the optical element 48, 148 is sized and shaped to allow passage of all or substantially all of the light emitted from the light assembly 24. The light fixture can be configured for various sizes and shapes of ceiling/wall openings, and the trim element is sized and shaped for such openings.
The bottom 42, 142 and peripheral flange 44, 144 portions of both of the low-incline and high-incline trim elements 40, 140 can have the same shape and configuration (for the trim elements configured for a given opening size and shape). However, the upper portions 46, 146 of the low- and high-incline trim elements 40, 140 are configured differently as described herein, and the optical elements 48, 148 of the low- and high-incline trim elements 40, 140 are preferably aligned at different angles relative to the plane of the peripheral flange 44, 144 of the trim element. In particular, the relative angle (θ1,
The optical axis 32 of the light assembly 24 will be perpendicular to the optical element 48, 148 when the lighting assembly 24 is pivoted relative to the enclosure 12 at an angle equal to the relative angle (θ1, θ2) of optical element 48, 148 the low- and high-incline trim elements 40, 140.
In addition, the optical element 48, 148 of each type of trim element 40, 140 can have a first end 58, 158 disposed between the optical axis 32, and the uphill end 54 of the bottom wall 34 of the enclosure when installed in the enclosure 12, and can have a second end 60, 160 disposed on the opposite side of the optical axis 32 when installed, that is, between the downhill end 56 of the bottom wall 34 of the enclosure and the optical axis 32. The first end 58, 158 of the optical element 48, 148 is closer to the plane of the peripheral flange 44, 144 than the second end 60, 160. Further, in the low-incline trim 40, a distance between the first end 58 of the optical element 48 and the plane of the peripheral flange 44 can be greater than a corresponding distance of the high-incline trim, specifically a distance between the first end 158 of the optical element 148 and the plane of the peripheral flange 144 of the high-incline trim. And, in the low-incline trim 40, a distance between the second end 60 of the optical element 48 and the plane of the peripheral flange 44 can be less than a corresponding distance of the high-incline trim, specifically a distance between the second end 160 of the optical element 148 and the plane of the peripheral flange 144 of the high-incline trim.
A purpose of the different configurations of the low- and high-incline trims, and in particular the different position and angle of the optical elements 48, 148 thereof, is to maintain a close (and minimal) but non-interfering distance between the optical element 48, 148 and the bottom portion of the (vertically-aligned) lighting assembly 24 (for example, as between the optical element 48, 148 and the bottom 30 of the reflector 26) throughout the range of ceiling inclines designated for the particular trim element.

The angle indicator 64 also includes a pointer 72 preferably fixed relative to the lighting assembly 24 which is adapted to align with the markings 66 at a particular inclination, such as the line markings 68 and/or the associated numerical markings 70. The pointer 72 can comprise an edge 74 of the lighting assembly 24 which aligns with the line markings 68, and such edge 74 can include a recess 76 on a portion thereof, aligned with and adapted to permit viewing of the associated numerical markings 70. The relative positions of the markings 66 and pointer 72 can be reversed such that the markings 66 are fixed relative to the lighting assembly 24 and the pointer 72 is fixed relative to the housing 12.
The markings 66 of the angle indicator 64 also preferably include a trim indicator 78 which is operable to indicate which trim element, among the low-incline and high-incline trim elements 40, 140, should be used for a range of inclination angles. For example, as shown in
The lighting fixture 10 described herein can be provided in a kit including the enclosure 12 with all of the components thereof described herein along with the low-incline trim element 40 and the high-incline trim element 140, and optionally mounting hardware for the light fixture.
A method of installing the lighting fixture 10 can include one or more of the steps (in any appropriate order) of providing the enclosure 12 with all of the components described herein, installing the enclosure 12 in an inclined ceiling/wall adjacent a ceiling/wall panel 18 in the manner and position described herein, adjusting an angle of the lighting assembly 24 relative to the enclosure 12 to a desired relative angle, such as a relative angle in which the optical axis 32 is vertical, optionally viewing the angle indicator 64 and/or bubble level 62 through the aperture 14 to attain the desired relative angle and/or vertical alignment of the optical axis 32, locking the lighting assembly 24 in the desired relative angle, optionally viewing the trim indicator 78 of the angle indicator 24 through the aperture 14 to determine the recommended trim element among the low-incline trim and the high-incline trim, selecting the appropriate trim element among the low-incline trim element and high-incline trim element, and mounting the selected trim element in the aperture 14.
As can be appreciated, the light fixture 10 can include three or more configurations of trim elements, which, for example, could comprise low-incline, mid-incline and high-incline trim elements adapted to for use within three adjacent ranges of relative inclination of the lighting assembly and enclosure, in the manner described herein.
