DETAILED DESCRIPTION

Before any embodiments are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. Use of “including” and “comprising” and variations thereof as used herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Use of “consisting of” and variations thereof as used herein is meant to encompass only the items listed thereafter and equivalents thereof. Unless specified or limited otherwise, the terms “mounted,” “connected,” “supported,” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings.

The present disclosure relates to a recessed light fixture including two or more planar optics, such as LED edge-lit panels, that are inclined relative to a housing. In the illustrated embodiment, the planar optics are positioned on either side of the housing and separate by an intermediate portion.

As shown in FIGS. 1 and 2, a light fixture 10 includes a frame or housing 14 and light emitting surfaces 18. In the illustrated embodiment, the housing 14 has a rectangular or square shape and is supported in a recessed position relative to a ceiling 4 (FIG. 1) such that a terminal surface 22 of the housing 14 is substantially flush with the ceiling. The light emitting surfaces 18 direct light output through a light emission opening 24. In the illustrated embodiment, the light emission opening 24 is positioned adjacent the terminal surface 22 and is bound by the perimeter of the housing 14. In some embodiments, the housing 14 may be sized to fit within a 2 ft. by 2 ft. square recess; in other embodiments, the housing 14 may have different dimensions (e.g., 1 ft. by 2 ft.; 1 ft. by 4 ft.; 2 ft. by 4 ft.; etc.).

Referring to FIG. 2, the housing 14 includes a pair of sides 26, a pair of ends 30 (first end 30a and second end 30b), and an intermediate portion 34 positioned between and parallel to the sides 26. In the illustrated embodiment, a longitudinal axis 38 of the housing 14 extends between the first end 30a and the second end 30b, and the intermediate portion 34 is centrally aligned with the longitudinal axis 38. Also, in the illustrated embodiment, the sides 26 and the intermediate portion 34 are formed by one or more extrusion processes.

Each light emitting surface 18 is formed as an edge-lit planar panel 18 that is supported in the housing 14. In the illustrated embodiment, the light fixture 10 includes two panels 18 positioned on opposite sides of the intermediate portion 34. As best shown in FIG. 7, each of the panels 18 is mounted in an inclined orientation relative to the light emission opening 24 (that is, relative to a plane formed by the terminal surface 22 of the housing 14), and one edge of each panel 18 is positioned closer to the terminal surface 22 than an opposite edge of the panel. In some embodiments, each panel 18 is oriented at an inclined angle, and the inclined angle between approximately zero degrees and approximately fifteen degrees. In some embodiments, the inclined angle is between approximately zero degrees and approximately ten degrees. In some embodiments, the inclined angle is between approximately zero degrees and approximately five degrees.

In the illustrated embodiment, the panels 18 are inclined between the sides 26 of the housing 14 and the intermediate portion 34. The inner edges 40 of the panel 18 that are adjacent the intermediate portion 34 are positioned closer to the terminal surface 22 than outer edges 42 of the panels 18 that are positioned adjacent respective sides 26 of the housing 14. Stated another way, when the housing 14 is supported within a substantially horizontal ceiling, the inner edges 40 are positioned lower than the outer edges 42. In addition, the inner edges 40 are spaced apart from the terminal surface 22. In other embodiments, the panels 18 may be inclined in a different manner.

As shown in FIGS. 3 and 5, in the illustrated embodiment each panel 18 includes a diffuser 62, a light guide 66, and a reflector 70. The diffuser 62, the light guide 66, and the reflector 70 are layered with respect to one another. The diffuser 62 is positioned proximate the terminal surface 22 of the fixture 10, and the light guide 66 is positioned between the diffuser 62 and the reflector 70. In other embodiments, each panel 18 may include only a reflector and a light guide, or may simply include a light guide.

In addition, as shown in FIGS. 3 and 6, light sources or light emitters 82 are positioned along at least one edge of each panel 18, and the light from the light emitters 82 is directed from the panel 18 through the light emission opening 24. The light emitters 82 include light boards supporting a plurality of light emitting diodes (LEDs). The LEDs are generally aligned with one another in a linear manner along the associated edge of the panel 18. In some embodiments, a cover 86 is positioned over the light emitters 82. In the illustrated embodiment, the light emitters 82a, 82b are supported on the sides 26 of the housing 14, with a first set of light emitters 82a positioned adjacent an outer edge 42 of one panel 18 and a second set of light emitters 82b positioned adjacent an outer edge 42 of the other panel 18. In other embodiments, light emitters 82 can be supported on the intermediate portion 34 and positioned adjacent the inner edges 40 of the panels 18.

The ends 30 of the housing 14 includes internal end walls 46 that are positioned adjacent the edges of panels 18, and the sides 26 include internal side walls 50 that are positioned adjacent the outer sides of the panels 18. As best shown in FIGS. 4 and 6, the internal side walls 50 are inclined inwardly from the terminal surface 22 toward the longitudinal axis 38 and toward a surface of the associated panel 18. Similarly, as best shown in FIG. 8, the internal end walls 46 are inclined inwardly from the terminal surface 22 toward the panels 18. Due to the inclined orientation of the panels 18, the internal end walls 46 have a depth that varies along the width of the fixture 10 (i.e., in a direction transverse to the center longitudinal axis 38).

Referring now to FIG. 6, the fixture 10 further includes associated electrical components, such as drivers, controllers, etc. for operating the light emitters 82 in the illustrated embodiment, an enclosure 90 is positioned above the intermediate portion 34 and extend substantially along a length of the intermediate portion 34. In addition, as shown in FIGS. 3 and 4, the fixture 10 includes a support 98 and a sensor 102 supported by the support 98. In the illustrated embodiment, the support 98 is positioned between one of the ends 30 and an end of the intermediate portion 34. The sensor support 98 includes a sensor housing 106, and a bracket 110 coupled to the sensor housing 106. The sensor housing 106 engages the end of the intermediate portion 34 (e.g., by a hook or tab received within a slot on the intermediate portion 34). In other embodiments, the support 98 may support an emergency battery test switch, either in addition to or instead of the sensor 102.

In other embodiments, as shown in FIG. 10, the fixture 210 may be constructed without a sensor support. In the embodiment shown in FIG. 10, an intermediate portion 234 extends between a first end 230a and a second end 230b of a housing 214. For clarity, features of fixture 210 that are similar to features of fixture 10 are identified with similar reference numbers, plus 200.

Although various aspects have been described in detail with reference to certain embodiments, variations and modifications exist within the scope and spirit of one or more independent aspects as described. Various features and advantages are set forth in the following claims.
