The present invention generally relates to lighting systems and more particularly to lighting systems that can be configured in a space.
Architectural lighting systems provide both a lighting function and an aesthetic function in the space to be illuminated. The challenge to the lighting designer is to deliver light where desired in the space while making the physical lighting fixtures used to deliver the light aesthetically pleasing. These challenges are commonly presented in office environments, including open offices, which have overhead grid ceilings. Lighting fixtures used in such architectural environments include recessed lighting and ceiling suspended lighting. Recessed lighting is relatively limited in how the light is delivered to the space and offers little in the way of aesthetic appeal. Conventional ceiling suspended lighting systems, such as linear fluorescent lighting, is generally more flexible in its light delivery capabilities and can be configured to create aesthetically pleasing architectural elements within a space. Nonetheless, existing ceiling suspended lighting systems still have limitations that limit the lighting designer's ability to create a configurable lighting system that delivers light within the space where it is most needed. Existing ceiling suspended lighting systems also tend to be limited to physical forms where the hardware, such as fixture housings, of the lighting system tend to dominate instead of the light emitting elements themselves.
The present invention is directed to a configurable lighting system that overcomes limitations presented by prior art lighting fixtures and systems and that expands the tools available to a lighting designer to create ceiling suspended lighting systems that are both aesthetically pleasing and capable of delivering light to precise locations within a space. The invention is particularly adapted for use in spaces having grid ceilings with defined spacings between suspension points within the grid framework of the ceiling, and can be adapted to present lighting elements to a space where the visual appearance of the lighting system is dominated by a pattern lights produced by the light emitting surfaces of the lighting elements.
The present invention involves a two dimensional lighting system having neural hubs that can be interconnected with or without additional straight elements in a manner that allows a lighting system to be configured in a pattern that can propagate out in a two dimensional plane from a single neural hub. A plurality of lighting elements can be connected to the neural hubs of the lighting system, as well as to any additional straight elements used to configure the lighting system, to form a neural pattern of lighting elements. Preferably, the lighting elements are planar form lighting elements such as OLED panels, which present a pattern of visually dominating light emitting surfaces to the observer of the lighting system. The propagated neural hub based lighting system produces both an aesthetically pleasing lighting environment and a two-dimensional lighting system that provides enhanced light placement capabilities. The system provides a wide range of design options for distributing light to different areas within a space and for achieving improved lighting application efficiencies.
The invention is uniquely be adapted for mounting below a grid ceiling system in a wide variety of configurations, including configurations involving the use of multiple neural hubs that propagate the system out in an extended pattern of lighting. In one aspect of the invention suspension, points for the system are provided at the neural hubs, which are located at the intersections of a hex pattern lighting system. With the neural hub suspensions, suspension point placements can be established that correspond to required suspension locations on a square or rectangular T-bar grid of a grid ceiling.
In another aspect of the invention, each neural hub can have a center section and three neural arms that radiate out from the center section. Each neural arm of the neural hub radiates from the hub's center section at an angle that preferably is 120 degrees from its adjacent arms. With this angular relationship between neural arms, an angular relationship of 120 degrees or multiples of 120 degrees can be maintained between the neural arms of multiple interconnected neural hubs and between any straight elements that may be connected to any neural arm of any neural hub. With the neural hubs in accordance with the invention, lighting patterns can be propagated out from a single neural hub in a neural hex pattern.
Each of the neural hubs can have lighting element connector rails to which the lighting elements of the system are connected and which provide wireways for wiring the light elements. The neural hubs can be joined together or to additional straight elements through these connector rails.
The neural hub preferably has three connector rails, each of which can have a curved mid-section and two straight terminal sections. The three connector rails preferably are substantially identical, with the curved mid-section of each rail having an arc of 120 degrees such that the straight terminal sections of each connector rail extend out 120 degrees relative to each other. A hanger bracket supports the three connector rails in a plane and holds the connector rails such that adjacent terminal sections of the rails extend radially outwardly from the center section of the hub in a spaced apart parallel relationship. These adjacent terminal sections form the backbone of the arms of the neural hub.
In addition to the neural hubs, the lighting system can include straight elements to expand the possible lighting configurations that can be created by a lighting designer. The straight elements can have parallel connector rails, which have a spacing that corresponds to the spacing of the adjacent straight terminal sections of the rails of the neural hubs that form the backbone of the neural arms of the hubs. This will allow the connector elements to be joined directly to the neural arms of the neural hubs.
The connector rails of the neural hubs and straight elements are preferably adapted to allow the lighting elements to be connected anywhere along the connector rails. The neural hex pattern formed by the rails of the hubs and straight elements can be populated with lighting elements that are evenly spaced along the rails or unevenly spaced or clustered on the rails to achieved desired light distributions. The light placement capabilities of the lighting system can be extended in multiple directions within a two dimensional plane by simply adding neural hubs and/or straight sections to the neural configuration of the lighting system.
Referring to the drawings,
The neural hex pattern of the lighting system has a further significant advantage where the lighting system is suspended under a conventional grid ceiling having two-by-two foot or two-by-four foot T-bar grids. As hereinafter described, the suspension points for the lighting system can be provided at the center of each neural hub of the lighting system. By placing the suspension points at the neural hub centers, it has been found that the neural hex pattern will allow the suspension point at each hub to be located on-center beneath desired suspension points on the grid ceiling, even with an extended hex pattern comprised of many neural hubs and straight elements.
With further reference to
The hanger bracket supports the three connector rails in a plane. Specifically, the spokes of the hanger bracket connect to and hold the connector rails at the mid-point of each of the rail's curved mid-section 25 such that the rails' terminal sections 27 extend radially outwardly from the center of the hub, and such that the terminal section of one rail extends in a close parallel relationship to the terminal section of the adjacent rail. Each of the paired terminal sections of the three rails provide the backbone for one the radiating neural arms of the neural hub, and can be structurally strengthened and maintained in parallel relation by suitable cross-bracing structures, such as by bridge brackets 30. It is seen that the connector ends 28 of the adjacent pairs of terminal sections of the connector rails form the connector ends of the neural arms of the neural hub.
The connector end of each to the hub's neural arms 19 is suitably provided with means for connecting the end of any one of the neural arms of the neural hub to the end of any one of the neural arms of another neural hub or to an end of a straight element 15. This end-to-end connection capability can be provided by any suitable means, such as by providing alternating male and female end configurations to the connector ends 28 of the hub's three connector rails 23 wherein connector ends of the paired rails of a neural arm of one neural hub of can slide into the connector ends of the paired rails of a neural arm of another neural hub and be secured in place, such as by set screws (not shown).
Each of the hub's three connector rails provides wireways (denoted by the numeral 26 in
Reference is now to
It can be seen that the connector rails 23 of the hub provide a continuous unbroken path from one neural arm of the hub to the hub's next neural arm. The curved mid-section of the rails causes this continuous path to sweep through the hub's center section 17. As mentioned above, lighting elements, such as OLED panels 29, can be operatively connected to any one of the rails of the hub, and anywhere along the path of any rail. Thus, the neural hubs of the lighting system can be populated with lighting elements in any desired distribution. They can be evenly spaced as illustrated in the drawings or they can be unevenly spaced or clustered in groups of elements anywhere on the rails. If connected to the rails with a relatively close spacing between the OLED panels as shown in the drawings, that planar light emitting surfaces 32 of the OLED panels 29 will dominate the visual appearance of the lighting system and substantially hide the underlying structural elements of the hub. Indeed, when illuminated, substantially the only thing visible to the observer will be the pattern of illuminated OLED panels.
The connector ends 28a of the connector rails of the straight element 15 can be adapted to connect to the connector ends 28 of the connector rails of the neural hub in the same fashion that the connector end of a neural arm of one neural hub is connected to the arm of another neural hub as above described. Suitably, all connections between all parts of the system are made in the same manner throughout the system.
The lighting system described and illustrated herein can be configured around the neural hubs or a combination of neural hubs and straight elements to span, in a neural hex pattern, as much of a ceiling as necessary to meet a lighting designer's lighting application needs. The lighting application will determine the spacing between the lighting elements along the rails. For example, at locations where more light is required, the lighting elements can be closely spaced to increase the amount of light at that location; at locations where less light is required, the lighting elements can be spaced further apart or eliminated altogether. Preferably, the lighting elements can be connected to the rails anywhere in the hex pattern above the space, including on the neural hubs. The confluence of the connector rails at the neural hubs provides an opportunity to bring a concentrated amount of light to the space beneath the neural hub locations. The ability to strategically place the neural hubs can increase the options of the lighting designer for meeting his or her lighting application needs.
Also, as above-indicated, when the planar lighting elements such as OLEDs are used, the lighting elements will dominate the visual appearance of the lighting system. This is particular true when the lights are turned on. When turned on, what the observer will see is an aesthetically attractive pattern of seemingly floating light emitting surfaces below the ceiling.
Any or all of the individual partial hexagons of the above-described neural hex pattern row could be stretched in length by adding a straight element, such as straight element 15 described above, between the arms of the neural hubs extending in the direction of the row, such as between connection 19b-19c and 19d-19e. Any or all of the neural hubs in each row can be selected as suspension points for the hex patterned rows of neural hubs. The extended hex patterns shown in
It is contemplated that installable sections of a configurable lighting system in accordance with the invention can be preassembled off-site, such as by the manufacturer, in accordance with a lighting configuration created for a particular space by a lighting designer. The preassembled sections could then be shipped to the project site and assembled and suspended by suspension cables dropped from the ceiling, such as a grid ceiling, at the predetermined suspension points, which would correspond to neural hubs hub locations. Power cords can be dropped from the ceiling at selected suspension points with the wires from the power cord being run through the center hanger bracket 21 of the correspondingly sited neural hub. Wires from the power cord can then connected to the wires (or conductors) in the wireways of the neural hub's connector rails 23. The ends of the wires emerging from hanger brackets and joinable ends of the connector rails of the system can suitably by provided with quick connectors (such illustrated by element 42 in
While the present in invention has been described in some detail in the foregoing specification and the accompanying drawings, it is not intended that the invention be limited to such detail unless otherwise indicated herein. It will be appreciated that variations of the illustrated embodiments would be readily apparent to persons skilled in the art. For example, the neural arms and center section of the above-described neural hubs could separate parts where the neural arms are attachable to the center section. And the neural arms of a neural hub could be of different lengths or shorter or longer than shown. Still further each of the connector rails 23 of the neural hub and/or the connector rails 23a of the straight element could be an unitary rail of a rail made up of joinable sections of shorter rail segments.
