V. DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

(12) While illustrative embodiments are described herein with illustrative embodiments for particular implementations, it should be understood that the invention is not limited thereto. Those skilled in the art with access to the teachings provided herein will recognize additional modifications, applications, and embodiments within the scope thereof, and additional fields in which the lighting systems described herein would be of significant utility.

(13) The following detailed description is merely exemplary in nature and is not intended to limit the applications and uses disclosed herein. Further, there is no intention to be bound by any theory presented in the preceding background or summary or the following detailed description.

(14) FIG. 1 is an illustration 100 of an exemplary downlight luminaire 102 configured for installation in a carveout area 104 of a substantially flat member, such as a ceiling 106. As noted above, the ceiling 106 may be associated with an office, a retail location, or similar environment. The luminaire 102 includes an exemplary mounting mechanism 108 constructed in accordance with an embodiment of the present invention.

(15) The mounting mechanism 108, discussed in greater detail below, assists the installation process and improves ease of installation of the luminaire 102 into the ceiling 106. The exemplary mechanism 108 simplifies the installation process and reduces the risk of injury while installing recessed fixtures through the ceiling carveout 104. This approach facilitates faster and more efficient installation of recessed lighting fixtures.

(16) In the exemplary embodiment of FIG. 1, the luminaire 102 can be easily inserted into the ceiling carveout 104 with a single forward motion occurring in only one direction. The installer is not required to push the luminaire in one direction for insertion through a carveout, then pull it in another direction to lock the luminaire into place, as required, using conventional approaches.

(17) The mounting mechanism 108 also simplifies the installation process by eliminating the need for holding springs, or mounting clamps, under tension while inserting the luminaire through the carveout 104. In this manner, the risk of injury to an installer is substantially reduced.

(18) FIG. 2 is a more detailed illustration 200 of the luminaire system 102 and the mounting mechanism 108 depicted in FIG. 1. By way of background, the luminaire system 102 includes a bezel 202, along with a housing 204 enclosing electronics, such as an infusion module and optics (not shown).

(19) A passive heat sink 206 provides cooling for the infusion module, the optics, and other embedded electronics associated with the luminaire system 102. Standard fasteners, such as rivets or screws, can be inserted through an opening 208 to fasten the mounting mechanism 108 to the housing 204.

(20) FIG. 3A is a detailed angular view of the mounting mechanism 108, shown in FIGS. 1 and 2. In FIG. 3A, the mounting mechanism 108 includes a bracket (e.g., base) 300, and an elongated clamp lock 302 slidably fastened within a pathway 301 of the bracket 300. For example, the clamp lock 302 is configured for slidable (i.e., up and down) movement in a lengthwise direction (L) within the pathway 301. A lip portion 303 of the clamp lock 302 is provided for locking the luminaire system 102 tightly within the ceiling carveout 104 during installation.

(21) A spring arm 304A of a spring clamp 304 is positioned in substantially parallel alignment with the clamp lock 302. The spring clamp 304 also includes a spring coil 304B attached atop an upper surface of the clamp lock 302 and fastened to the bracket 300 about a pin 306, axially disposed through the spring coil 304B. The embodiments of the present invention are not limited to the spring clamp 304 depicted in FIGS. 2-3. Other suitable spring clamp configurations are available, as understood by those of skill in the art, and would be within the spirit and scope of the present invention.

(22) The pin 306 is attached to sides of the bracket 300 through openings 307 in a widthwise direction (W). Prior to installation of the luminaire system 102, as illustrated more fully below, the spring arm 304A is locked into the substantially parallel arrangement (i.e., vertical position) with the clamp lock 302 via a clamp lock top portion 302B.

(23) FIG. 3B provides an exploded view of the mounting mechanism 108 of FIG. 3A, along with more detailed views of the bracket 300, the clamp lock 302, the clamp lock top portion 302B, the lip 303, the spring clamp 304, the spring arm 304A, and the spring coil 304B.

(24) FIG. 4A is an illustration of the mounting mechanism 108, attached to the housing 204, prior to installation of the luminaire 102 through the ceiling carveout 104. Before installation, the spring arm 304A is in locked substantially vertical alignment with the clamp lock top portion 302B, as shown. A distance 400 separates the lip portion 303 from a bottom surface 402 of the ceiling 106.

(25) FIG. 4B is a more detailed illustration of the mounting mechanism 108, shown in of FIG. 4A, prior to installation. In FIG. 4B, the locked vertical alignment between the spring arm 304A and the clamp lock top portion 302B is more clearly visible. As noted above, the mounting mechanism 108 provides a more stable installation of the luminaire system 102 within the carveout area 104. To facilitate installation, and installer need only position the luminaire system 102 within the carveout area 104 and gently apply pressure to the luminaire 102 in a vertical direction (V) to facilitate its secure positioning.

(26) FIG. 5A is an illustration of the mounting mechanism 108, after installation of the luminaire system 102 in the ceiling carveout 104, in accordance with the illustrious embodiments. After the installer applies pressure in the vertical direction (V), as discussed above, the entire mounting mechanism 108 moves vertically until the distance 400 decreases to 0. The gap 400 disappears when the lip 303 contacts (i.e., hooks onto) the bottom surface 402 of the ceiling 106.

(27) When contact is established between the lip 303 and the bottom surface 402, as the luminaire moves in the vertical direction (V), the bracket 300 and the spring arm 304A continue to move vertically. During this vertical movement, the clamp lock 302 remains in the vertically locked position.

(28) As the bracket 300 and the spring arm 304 continue moving vertically, a tip of the spring arm 304A eventually rises above the clamp lock top portion 302B, releasing the locked position of the spring arm 304A. Tension within the spring coil 304B releases the locked vertical alignment, forcing the spring arm 304A to press against a top surface 501 of the ceiling 106. This process is illustrated with reference character 502 of FIG. 5A.

(29) As discussed above, the lip portion 303 can be released, or pushed by use of an installer's finger. Such a release could become necessary, for example, if one or more surfaces of the ceiling 106 is deformed or otherwise irregular, or if the edge of the ceiling 106 is not sharp enough to activate the mounting mechanism 108.

(30) FIG. 5B is a more detailed illustration of the spring arm 304 released to press against the top surface 501 of the ceiling 106 to secure the installation of the luminaire 102.

(31) FIG. 6A is an illustration of the mounting mechanism 108, attached to the housing 204, during an exemplary locking step 601. Prior to installation, an installer may lock the mounting mechanism 108, in preparation for installation, by rotating the clamp spring 304 up to vertical position beyond clamp lock 302, in step 601. Step 601 prepares the luminaire 102 for insertion through the ceiling carveout 104.

(32) FIG. 6B is an illustration of exemplary stages occurring during installation of the luminaire 102 (attached to the housing 204) through the carveout 104. For example, in positioning stages 602 and 604, after the luminaire 102 is inserted through the carveout 104, an installer need only push the luminaire 102 in a vertical direction (V), as indicated by the arrow. As the installer continues to push the luminaire 102, positioning it forward in the vertical direction (V), the clamp lock 302 prevents the spring arm 304A from being released during positioning. More particularly, as depicted in stage 604, the spring arm 304A is prevented from being released until the lip 303 contacts the bottom surface 402 of ceiling 106.

(33) When the vertical movement of the luminaire 102 causes the spring arm 304A to extend vertically beyond a height of the clamp lock top portion 302B, as depicted at stage 606, the spring arm 304A is released. Upon release, the spring arm 304A rotates in a direction towards the top surface 501, as depicted in stage 606. The release of the spring arm 304A occurs as a result of tension created moment within the spring coil 304B. Thus, when the spring arm 304A is released, spring tension is applied to the top surface 501 of the ceiling 106 to complete positioning of the luminaire 102, as depicted at stage 608. This tension continues to pull the entire luminaire system 102, in the vertical direction (V), securing it into a stable position.
