[0018] FIGS, 1-5 illustrate a light fixture or luminaire 10 including a housing 14, clips or brackets 18, and an enclosure 22. As shown in FIG, 3, the housing 14 supports one or more light-emitting elements or light sources (e.g., light-emitting diodes or LEDs - not shown) and a lens or optic 26 for providing a desired light output. In the illustrated embodiment, the housing 14 is formed as a thin, disc-like structure having a first side 30 and a second side 34, and the optic 26 is formed on the second side 34. In other embodiments, the housing 14 may have a different shape. The brackets 18 are coupled to the housing 14 and extend from the housing 14 in opposite directions. The brackets 18 may be coupled to a support structure (e.g., a stud or beam - not shown) to support the luminaire 10 relative to a wall or ceiling. In the illustrated embodiment, the brackets 18 have a U-shape; in other embodiments, the brackets may have a different shape.

[0019] Referring to FIGS. 1, 4, and 5, the enclosure 22 houses and/supports one or more drivers for driving electric current to the light sources. One or more wires or conduits 42 provide electrical communication between the drivers in the enclosure 22 and the light source(s) in the housing 14, The enclosure 22 is removably coupled to the housing 14 (e.g., by fasteners 46). In the illustrated embodiment, the enclosure 22 may engage or be coupled to the first side 30 of the housing 14, opposite the optic 26. As shown in FIG. 6, the fasteners 46 may be removed from one or more mounting features 50 to uncouple the enclosure 22. Referring to FIG. 7, the enclosure 22 may therefore be separated from the housing 14 while still electrically connected to the light source via the conduit 42. As a result, the enclosure 22 may be secured to a separate portion of the support structure.

[0020] In some circumstances, the presence of studs or beams located behind a finished surface (e.g., drywail) may interfere with installing an electrical box and/or fixture in a desired position, and may limit the types of electrical boxes/fixtures that may be installed in that position. This problem may be further complicated if fixture is a recessed fixture. The enclosure 22 of the luminaire 10 can be directly coupled to the housing 14, or the enclosure 22 can be separated from the housing 14 and supported remote from the housing 14. The removable coupling provides better versatility for mounting the luminaire 10.

[0021] During installation, an operator may first try to attach or mount (e.g., on a wail or ceiling) the luminaire 10 with the enclosure 22 directly coupled to the housing 14. However, the operator may encounter a stud or support member in the desired mounting position for the luminaire 10. The operator can uncouple the enclosure 22 from the housing 14 while the driver(s) in the enclosure 22 remain in electrical communication with the light source(s) in the housing 14. The operator may then mount the housing 14 in the desired position, and mount the enclosure in a different location offset from the housing 14, for example, on the support member.

[0022] In the illustrated embodiment, the mounting features 50 are coupled to the enclosure 22; in other embodiments, the enclosure 22 may be removably coupled to the housing 14 in a different manner. In another exemplary embodiment, illustrated in FIGS. 8-10, biased retention springs 54 engage mounting features 50 to removably couple the enclosure 22 to the housing 14. In the illustrated embodiment, the springs 54 are positioned on the housing 14 and the mounting features 50 are positioned on the enclosure 22; in other embodiments, springs may be positioned on the enclosure 22 and the mounting features may be positioned on the housing 14. As shown in FIG. 9, the biased retention springs 54 may be uncoupled from the mounting features 50 (e.g., by depressing a biasing member) to uncouple the enclosure 22 from the housing 14. The enclosure 22 may be separated from the housing 14 while still electrically connected to the light source via conduit 42. [0023] In some circumstances, the presence of studs or beams located behind a finished surface (e.g. drywall) may interfere with installing an electrical box and/or fixture in a desired position, particularly with regard to maintaining electrical connection throughout the installation process. In some embodiments, the conduit 42 includes a first portion 58 operably coupled to the light source, and a second portion 62 operably connected to the enclosure 22. The first portion 58 and the second portion 62 are operably connected together by an intermediate connector 66. The intermediate connector 66 includes a first connector 70 coupled to the first portion 58 of the conduit 42, and a second connector 74 coupled to the second portion 62 of the conduit 42. The first connector 70 is engageable with the second connector 74 to enable electrical communication between the enclosure 22 and the light source, and disengageable to facilitate luminaire 10 installation.

[0024] During installation, an operator may first try to attach or mount (e.g., on a wail or ceiling) the luminaire 10 with the enclosure 22 in electrical communication with the light source. The operator may encounter a stud or support member however, that makes installing the luminaire 10 with the enclosure 22 in electrical communication with the light source difficult. In another situation, the operator may have trouble securing the enclosure 22 to a separate portion of the support structure or a different support structure while the enclosure 22 is in electrical communication with the light source. The operator can disengage the first connector 70 of the intermediate connector 66 from the first connector 74 to proceed with the installation, and the first connector 70 can be re-connected to the second connector 74 to re-enable electrical communication between the enclosure 22 and the light source when convenient to do so.

[0025] In another situation referring to the embodiment illustrated in FIG. 8 and FIG. 9, an operator may first try to attach or mount (e.g., on a wall or ceiling) the luminaire 10 while the first connector 70 is not engaged with the second connector 74 so that the enclosure 22 is not in electrical communication with the light source. The first connector 70 can be subseqneutly connected to the second connector 74 to enable electrical communication between the enclosure 22 and the light source when convenient to do so.

[0026] The embodiment(s) described above and illustrated in the figures are presented by^¬ way of example only and are not intended as a limitation upon the concepts and principles presented herein. As such, it will he appreciated that variations and modifications exist within the scope and spirit of one or more independent aspects as described.
