Description

FIELD OF THE DISCLOSURE

The present disclosure relates to acoustic panels.

BACKGROUND

Lighting and acoustics are two principal features in the design of a room space. Typically, however, acoustics and lighting are considered separately, and satisfied by light fixtures and acoustic panels of different configurations of shape, texture, thickness, placement, orientation and the like.

It may thus be desirable to provide novel approaches for lighting and/or acoustics, or at least to provide the public with one or more useful alternatives.

Referring to FIGS. 1 and 2, there is provided an elongate acoustic panel 10 for installation in an interior space. The panel 10 has at least one, in this case a pair of acoustic surfaces 12, 14 and an adjacent elongate edge region 16, along with a distribution of light emitting elements 18, such as, but not limited to, LED's, OLED's and/or other light emitting elements (LEE's) and any devices herein after created and/or devised to provide the same or similar function and/or effect, along the edge region 16. Thus, the LED's described in exemplary embodiments below may be replaced by other LEE's as needs and features may require, or be of improved value in some cases.

The acoustic surfaces 12, 14 include respective boundary regions 12a, 14a. As can be seen in the exemplary embodiment of FIGS. 1 and 2, the edge region 16 is positioned adjacent the boundary regions 12a, 14a, thus placing the edge region 16 between them. The acoustic surfaces 12, 14 are provided on respective outer acoustic panel portions 22, 24, which may be part of an extruded structure 26 or the like with an outer layer of acoustic material thereon. End caps 27 may then be provided on each end to close the structure.

In some exemplary embodiments, one or both of the boundary regions 12a, 14a may be configured in a first mode in which the boundary regions 12a, 14a are aligned with the edge region 16, as shown in FIGS. 1 and 2. In this instance, the boundary regions 12a, 14a and edge regions 16 may follow one or more linear paths as shown at 28 which may be joined by transition regions 30. The transition regions may be smooth curved and thus present a sinusoidal-like profile, at least in part, as shown in FIG. 1. Alternatively, the transition regions may provide more linear profiles, as shown schematically by line 32 in FIG. 3. Alternatively, as shown in FIGS. 7 and 8, the path 28a may be planar along most or all of its length linear without a transition region (of the type shown at 30 and 32), or may for example have one or more such transition regions provided symmetrically or asymmetrically along its length. (FIG. 20, for example, illustrates a number of panel assemblies 34 which have varying dimensions, symmetries and the like.) The LED's 18 may then be located along the linear paths, the transition regions, or both, depending on a desired lighting effect. The shape and/or configuration of the edge region 16 may, in some exemplary embodiments, be patterned to provide, when installed, transition regions to direct lighting to designated regions of the inner space. In some exemplary embodiments, the paths may be linear in repeating or non-repeating sections, which may be joined by angled or curved sections 44a, 44b to form acoustic panels that can follow a corner or other transition in an interior space, such as shown in FIGS. 6a and 6b, Further, the panel itself may be curved along a radius as shown in FIG. 6c.

In some exemplary embodiments, such as shown in FIGS. 7 to 9, one or both of the boundary regions 12a, 14a may be configured in a second mode in which one or both of the boundary regions 12a, 14a extend beyond, so as to overlap or be offset relative to, the edge region 16. Thus, the one or more transition regions 30 may thus transition the boundary regions 12a, 14a between a zone corresponding to the first mode and a zone corresponding to the second mode. Further, in some exemplary embodiments, as shown in FIGS. 8 and 9, the first mode of one of the boundary regions, as shown for boundary region 12a, may align with the second mode of the opposed boundary region 14a.

Referring to FIG. 10, each of the boundary regions 12a, 14a may be provided with peripheries 12b, 14b providing a border in the plane of the edge region 16. An optic lens 33 may be positioned between the peripheries 12b, 14b to cover the distribution of LED's 18, as shown, or the LEDs may alternatively be exposed in another configuration, either with no lens 33 or by a mesh or screen structure or the like, not shown. Thus, in the first mode for both the linear paths 28 and the transitions zones 30, the lens 33 may be flush with the peripheries 12b, 14b, while in the second mode, the lens 33 may be overlapped by the outer panels in a number of different configurations from a relatively shallow overlap, to a deep overlap as shown in FIG. 11. FIG. 11 further illustrates a variation for the optics of the lens 33. Other lens configurations may be deployed if desired. The overlap, shallow or deep therebetween, may be provided by just one of the outer panel portions, or by both opposed outer panel portions. In the latter instance, the overlap of the opposed outer panel portions may an aligned overlap as shown in FIG. 7 or an offset or misaligned overlap as shown in FIGS. 8 and 9. In the latter case, the offset overlap may be regular to form a repeating pattern of overlap or may be a random overlap.

Thus, the configurations of the exemplary one or more acoustic panel outer surfaces 12, 14 and the edge region 16 provide a number of variables which may be combined to present a wide range of edge profiles of the acoustic panel 10 to present a variety of visual and/or acoustic effects in an interior space, for example when suspended or fastened to a ceiling structure, such as a T-bar ceiling structure, or another ceiling structure, as shown for example in FIG. 19, or a wall structure, and among other possible shapes and configurations. In this case, the acoustic panels may be assembled, end -to-end, to form an assembly 34, as shown in FIGS. 17 to 19 in one example, to provide an overall length corresponding to designated design parameters for the space.

Referring to FIGS. 12 and 12a, in some exemplary embodiments, the outer panel portions 22, 24 may be provided on either side of at least one inner panel portion 20, and formed of sound absorbing material or of various combinations of sound absorbing materials presently known, or hereinafter discovered, which may include, by way of illustration but not limitation, porous natural or polymeric fibers, foams, particulate matrices and the like. Alternatively, the outer panel portions 22, 24 may be provided with an acoustic outer cover layer, once again by way of illustration but not limitation, such as felt or other fibrous or porous material. The outer panel portions 22, 24 may be planar as shown in FIGS. 12 and 12a, or be provided with other non-planar configurations as shown schematically by line 36 in FIG. 5, in conjunction with other panels as may be placed in an acoustic configuration in the ceiling structure. Still further, the inner and outer panel portions may bonded together to form a composite panel, or be portions of a unitary structure formed from a single blank of acoustic material, or a blank of material wrapped in an acoustic material, or the like. The LED's 18 may be located in a recess, as shown at 36, or instead located along the edge region 16 with or without a lens 33.

In some exemplary embodiments as shown in FIGS. 7 to 9, 11, 13, 15 and 16, the panel 10 may be formed as a box-like, at least partially hollow (such as shown in FIG. 15), or extending wall baffling enclosure 40, with an opening 40a to an interior space 42 in which one or more lighting elements may be located, either as the distribution of LED's 18 as above described, or as one or more discrete light emitting units as shown schematically at 44. In some exemplary embodiments, hollow structure, or extending walls may provide further disruption of sound wave propagation, which may occur as a result of interfering with the propagation of the sound waves that encounter the irregular structures which also prevent, scatter, or at least reduce sound wave reflection.

Thus, in some exemplary embodiments, acoustic panels may provide for improved acoustic effect in an interior space while also providing improved lighting by way of LED's 18, when suspended either alone or in end-to-end assemblies 34, in one or more designated repeating curved, rectangular, linear, circular or other patterns, at least in part as shown, in the interior space, so that the upright acoustic surfaces 12, 14 may be operable for a desired acoustic effect, while the distribution of LED's 18, or light emitting units 44, along respective longitudinal edge regions may provide effective interior lighting. In the exemplary embodiments of FIGS. 6a and 6b, an acoustic panel assembly 34 has a pair of acoustic panels 10 jointed by a joining sections 46a, 46b which may be angular, as shown in FIG. 6a, curved as shown in FIG. 6b, or another configuration and which may or may include not one or more acoustic features and LEE's 18 of the acoustic panels 10, as shown in FIG. 6b. In this case, the LED's or light emitting units may be provided either on a lower longitudinal edge region to provide direct lighting, an upper longitudinal edge region to provide indirect lighting, or both. FIG. 6c shows a panel 10 which is curved about a radius.

The acoustic panels may be mounted in a pendant fashion, as shown in FIG. 19, or in a non-pendant fashion, either on the ceiling, or a wall surface. The acoustic panels as shown herein may also be used in an inverted configuration so that the boundary regions 12a, 14a and the edge region 16 face upward toward the ceiling structure or wall structure, as the case may be.

In some exemplary embodiments, the panel may be prepared to perform as a baffle, with outer acoustic outer panel portions which may incorporate soundproofing materials to diffuse standing waves and reflections, such as open cell foams, fiberglass, porous or diffuse materials, among other possible materials, with different surface shapes and configurations to provide variations in absorption ratings for a particular interior space. For example such panels may have a thickness and density suitable for a designated Noise Reduction Coefficient (“NRC”). For instance, an acoustic product with a 0.95 NRC rating means that 95% of sound in the space is absorbed, while the other 5% is reflected. Thus, some exemplary embodiments may provide at least one sound absorbing surface with an NRC rating ranging from about 0.50 to about 0.99, or more particularly from about 0.75 to about 0.95.

In some exemplary embodiments, the acoustic panels may have one or more cross sectional widths X ranging from about 1.5 inches to about 6 inches, in some cases from about 2.5 inches to about 4.5 inches, while other dimensions may also be applicable in some cases.

In some exemplary embodiments, the acoustic panels may have one or more cross sectional depths Y1, Y2 ranging from about 2.5 inches to about 15 inches, in some cases from about 4 inches to about 10 inches, in some cases, in some cases from about x inches to x inches.

While the present disclosure describes various exemplary embodiments, the disclosure is not so limited. To the contrary, the disclosure is intended to cover various modifications and equivalent arrangements, as will be readily appreciated by the person of ordinary skill in the art.
