Light fixtures come in many different varieties and styles. Some light fixtures are relatively simple, and provide little more than a housing for a light bulb. Other light fixtures are ornate, with multi-faceted designs. Some light fixtures are designed for commercial settings, while others are designed for residential use. Coverings for light fixtures are often made of plastic, metal or glass. Glass light fixtures tend to irradiate most of the light generated by the light source, while other fixtures made of metal or plastic may diffuse or direct the light in specific directions. Light fixtures are used in nearly every room in a building and, as a result, many different configurations of styles and materials are available.
Many rooms, especially in commercial settings, are quite large and require many different light fixtures to provide sufficient light to the room. These large rooms also bring other challenges including reverberation. Indeed, conference rooms and other large gathering rooms may suffer from high levels of sound reverberation, which causes voices and other sounds to appear muddled and unclear. This reverberation, even in small amounts, can cause listeners to tune out presenters, speakers or performers, as the lack of tonal clarity makes listening more labor intensive for the audience.

As shown in
The panels 101 may be constructed using one or more materials that are designed to dampen sound. For instance, in one embodiment, felted polyethylene terephthalate (PET) fibers may be used. PET fibers may be manufactured and felted using a variety of known felting processes. The resulting felted PET fibers can be press-formed or heat-formed into rigid structures, such as the panels shown in the sound-dampening light fixture of
The panels may be shaped in a specified manner that dampens sound. For instance, as shown in
In some cases, for example, the shape and size of the panels may be based on the size and shape of the room into which the panels (and the corresponding light fixture) are to be placed. Some sizes and shapes of panels may be more conducive to reducing echoes and reverberations in larger or smaller rooms, crowded or empty rooms, rooms with large amounts of glass or other highly reflective materials, etc. Accordingly, each sound-dampening light fixture may be specifically designed for a specific room or environment. The shape, size and thickness of each panel may be changed to accommodate different room types.
The sound-dampening light fixture 100 may be hung by itself, or may be connected to other sound-dampening light fixtures (as described further below with regard to
As shown in
As shown in
In embodiments where linking members 201 and panels 101 are all interchangeable, a user may be able to design a large collective fixture (e.g. 200A) made up of many different smaller fixtures (e.g. 100A-100E) that is tailored to the acoustics of a given room. The collective feature may include different lengths and sizes of linking members, as well as different shapes and sizes of panels, forming many variations in overall structure. Thus, regardless of how large or small the room, smaller light fixtures may be combined into larger collective fixtures that provide both sound-dampening and lighting functionality.
In such cases where large collective sound-dampening light fixtures are used, each light source (e.g. 109A of
In some embodiments, both the interconnecting members that connect the sound-dampening light fixtures together, as well as the panels on each of the fixtures, are constructed using the same sound-dampening material (e.g. felted PET). In other cases, the interconnecting members and the panels are constructed using different sound-dampening materials, or using different thicknesses or designs of sound-dampening materials to alter the acoustics in a given area. Moreover, some panels may have angular, protruding portions that are further designed to reduce reverberations in a room.
As with the embodiments described above, the structural center portion of sound-dampening light fixture 300 may be substantially cylindrical in shape. In other embodiments, the structural center portion may be rectangular, square, triangular, or may be an oblong or hand-formed shape. In such cases, the interconnecting rings may be correspondingly rectangular, square or triangle-shaped, or may be shaped to contour the oblong or hand-formed design. In this manner, it will be understood that although the interconnecting ring references a circular ring shape, it will be understood that the interconnecting ring may take a variety of different forms. Regardless of shape, the interconnecting ring allows panels to be connected to the structural center portion, whether removably or permanently.
In some cases, implementations of the invention as claimed, when actually used in rooms, have been empirically shown to reduce the in-room acoustic coefficient (i.e. the noise reduction coefficient or NRC) to nearly 1.0. On a scale where 0 is a perfect sound reflector (e.g. glass), and where 1.0 is a perfect sound absorber (e.g. an anechoic chamber), the sound-dampening light fixtures described herein can bring the NRC in a room to nearly 1.0, meaning that sounds do not echo or reverberate off of the sound-dampening light fixture. This high level of NRC is achieved despite the felted PET fibers having a substantially lower rating when tested alone (NRC was 0.65). The design of the panels, the fixture, and the combined collective fixture can have a great influence over how well sound is dampened in a given room.
In one specific embodiment, a sound-dampening light fixture (e.g. 100 of
Each room into which the sound-dampening light fixture 100 is to be installed is unique. Depending on whether the flooring has carpet or wood, or whether the walls have windows or doors, or other factors may dictate how conducive a room is to reverberations. The panels and the light fixture itself may be manufactured in a shape and design that is configured to dampen sound waves that come into contact with the light fixture. Rooms that are prone to reverberation (such as rooms with wood floors and multiple windows) may need a more aggressive design that dampens more sound, while other rooms (such as rooms with carpeted flooring and few windows) may not need as much sound dampening. In large rooms, a given sound-dampening light fixture may be connected to other sound-dampening light fixtures via interconnecting members that connect to connection points of the interconnecting rings. Each sound-dampening light fixture is modular, and can be connected to any number of other sound-dampening light fixtures.
Both the panels and the interconnecting member that connects the sound-dampening light fixture and the other sound-dampening light fixture(s) may be constructed using a sound-dampening material such as felted polyethylene terephthalate (PET) fibers. Each panel 101 connects to the center structural portion 102 either directly or via an interconnecting ring or set of rings. These interconnecting rings may be placed at the top, bottom, middle or other part of the structural center portions. The structural center portion itself may be constructed from a translucent material that allows light to be emitted. Thus, when a light source 109 is placed within the structural center portion, light can travel through the center portion. Different thicknesses and levels of opacity may be used to subdue the light and provide a customized ambience for the room.
For example, if an interior designer was designing the lighting and acoustics of a given room, the interior designer could select a specific type of material for the structural center portion. The designer could also link one or more sound-dampening light fixtures together in a formation that itself is designed to reduce sound vibrations, specifically for that room. Still further, the interior designer could use the controllers 111 in the light fixtures to specify where light is to be shone, at which intensity, and at which times. The interior designer (or operator of the room) may use an application to program the controllers, and the controllers may store the program in memory (e.g. in electronically erasable programmable memory (EEPROM)). Different programs may be stored and initialized by a user for different settings or functions. Using the light controller, a user can control many different properties of the light source, in real-time or in a pre-specified program.
Each manufactured sound-dampening light fixture is modular and may be combined with other sound-dampening light fixtures using interconnecting panels. A combined structure may be manufactured that includes multiple modular sound-dampening light fixtures linked together via these interconnecting sound-dampening panels. Each sound-dampening light fixture may be attached to a ceiling mount via a support line. In such cases, a first end of the support line is attached to the ceiling mount and a second end of the support line is attached to a mount on the structural center portion 102. The panels (including the interconnecting panels) may be attached to connection points of the interconnecting rings. These connection points may include snap-fit connections or magnetic connections where magnets embedded in the panels align with magnets embedded in the interconnecting rings.
In another specific example, a sound-dampening lighting apparatus is provided which includes the following: an interior frame (e.g. 102) that provides structural support for one or more external panels 101, a hanging apparatus connected to the interior frame, and an interconnecting ring 103 that includes various connection points 104 for connecting the external panels to the interior frame. The panels extend laterally away from the interior frame, as shown in fixture 300 of
Each of the panels in the light fixture is interchangeable, allowing users to switch panels of different sizes and shapes to dampen sound in a specified manner. Indeed, as noted above, the lighting apparatus may be designed for a specified room according to specific room characteristics. As such, a user may be able to specify a minimum amount of light that is to be provided by the lighting apparatus and a minimum amount of sound dampening is provided for the room. Each fixture in a collective fixture may be individually controlled to provide lighting in a specific direction or intensity. Specific sizes and shapes of panels may also be used to tune the acoustics in a room. The sound-dampening baffle and lighting apparatus may be designed, for example, to dampen sounds between approximately 250 and 4,000 Hz, which is the frequency range typically used by human voices. This ensures that as people speak to each other within the room, their voices do not reverberate or echo, reducing the likelihood that any given person will be hard to listen to or understand.
Accordingly, sound-dampening light fixtures are described herein. The fixture's panels may be sized and shaped in a manner that reduces echoes and reverberations within a room, giving the room optimal acoustic properties for communication. Similarly, the arrangement and number of panels per fixture can be changed or adapted to reduce echoes and reverberations within a room. Still further, the number of fixtures in and the shape of an interconnected array of light fixtures can be varied accordingly to tune the acoustics of the room. Substantially any shape or size of array may be installed in a room, from a single fixture, to a plurality of interconnected fixtures that cover the entire ceiling and/or walls. The sound-dampening light fixtures provide the ability to cover the ceiling and/or walls with light sources that are aesthetically pleasing and acoustically functional, and still provide open access to the ceiling/wall and associated hardware such as sprinklers, smoke detectors, or other mechanical features.
The concepts and features described herein may be embodied in other specific forms without departing from their spirit or descriptive characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the disclosure is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
This application claims the benefit of and priority to U.S. Provisional Patent Application Ser. No. 62/508,529, filed on May 19, 2017, entitled “FELT ARRAY” which application is incorporated herein by reference in its entirety.
