20100236154
The present description is directed to lighting and shade components for building exteriors, and more specifically, to an exterior panel with lights for a building.
Commercial buildings such as office buildings or apartments are expensive to build, maintain, and repair. The exterior of buildings can be damaged by weather or people. Other costs associated with buildings include temperature control. It is further desired to light buildings for safety and aesthetic reasons.
An aspect of the present disclosure is a building component that protects an adjacent location, such as a building, from sunlight or other hazards and provides an exterior lighting system. The component can be a panel that includes a body having a height and a width, a plurality of apertures in the body, and a series of undulations in the body, at least one of the undulations including a peak extending in a width direction. In an example, each of the undulations includes a peak extending in the width dimension and the undulations creating a repeating peak and valley pattern in the vertical direction. In an example, the plurality of apertures is parallelograms that include a corner at a respective one of the peaks of the undulations. In a further example, the plurality of apertures includes a corner at respective valley of the undulation. In a further example, the plurality of apertures defines an open area in the body in the range of about 40% to about 70%. In an example, the series of undulations include at least ten undulations in a height direction. In an example, the series of undulations form an angle from a peak to a valley up to an adjacent peak in a range of about 150 degrees to 170 degrees. In an example, the series of undulations form an angle from a peak to a valley up to an adjacent peak of about 160 degrees. In an example, the body includes a solid outer perimeter free of apertures. In an example, the body has a parallelogram shape and connection points at at least one of the corners. The lighting system is used to light the panel or a plurality of panels.
In a further aspect of the present disclosure, any of the above examples can be part of a building system or a building that include a wall, an exterior connection system fixed to the wall, and a panel system connected to the exterior connection system. The panel may include any of the above examples or other details recited herein.

The body 105 is defined by a continuous peripheral band 107 and an interior portion 109. The band 107 is a continuous strip of material, such as a metal. The band has a width of about 4 inches in an example. The width of the band 107 can be in a range of about 1 inch to about 6 inches. At various locations in the band 107, attachment points 113 are provided. These attachment points 113 can be through holes for receiving fasteners, such as bolts, screws, and rivets. In other examples, the attachment points 113 are adapted to receive other fasteners types, such as clamps, adhesives, etc.
The interior portion 109 includes a plurality of apertures 110 extending through the body 105. The plurality of apertures 109 are aligned in rows and columns. In an example, the number of rows equals the number of columns. In the
The panel 100 further includes an undulating pattern in the body 105. The undulation patter creates peaks 121 and valleys 122 in the body 105. At least one peak is aligned at one of the corners of the apertures 110 or at the intersection of the strips 115. The peaks 121 and valleys 122 alternate in an example. The peaks 121 and valleys 122 alternate along the entire height of the panel 100. The apertures 110 extend on two adjacent webs such that the aperture extends onto both an upslope and a downslope of a peak.
The lighting system 150 includes a light 151 comprising a base 152 on which is mounted a light source 154. Electrical circuit 155 is within the base 152 and is electrically connected to light source 154. An electrical conductive wire 156 connects the electrical circuit 155 to a remote controller or other electrical circuits (not shown in
The lighting system 150 illuminates the panel 100 and interacts with the undulating pattern of the panel to create a lighting effect. Across the entire panel system, many panels can attach to one another or be adjacent to on another, the angle 125 of such panels can be unique to create various images and interact with light from both the sun and other sources. The angle 125 can be unique to the path of the sun for a given location (latitude & longitude) of the building to optimize energy usage and visual appeal. In this example all elements of panel 100 may be designed specific to the sun path over the course of a year to achieve the functional and aesthetic design intent. Moreover, the number and size of the apertures 110 in a panel and the angle 125 create a certain lighting effect. In one example, adjacent panels can have different angles 125 or different apertures 110 to create differing lighting effects on the outside of a building.
The panel 100 for ease of construction, durability, and strength is free from glass or polymers in the apertures and in the remaining body 105. The apertures are therefore through holes that allow light to pass through the panel 100. The angle 125 also assists in defining how much light is reflected. The angle 125 also defines wherein the light is reflected. The interior web of the panel body 105 and the peripheral band 107 block some of the light and reflect it away from the back side of the panel. When the panel 100 is mounted in front of a building wall only a portion of the available sunlight directly impinges on the building itself. In an example, the apertures 110 create a panel 100 that has an open area of about 43%. In an example, the open area of a panel is in the range of about 40-70%. In an example, the open area of a panel is in the range of about 45-60%. The amount of panel open area depends on the application of the panel. For example, in a warm climate, e.g. tropics or subtropics, such as Saudi Arabia, where it is desirable to keep buildings cooler during the daylight, a lower open area may be used to block more sunlight from impinging on a building. Examples of such an open area are 45% or less. In other applications of the present panel 100, it may be desirable to have more open area as the panel is adapted to protect the building from catastrophic events, such as severe weather, e.g., hurricane, typhoon, tornado, tsunami, etc. or human caused damage, e.g., riot, military action, etc. These applications may have an open area of 70% or less. In cooler climates, i.e., 45 degrees or greater north or south of the equator, there is a tradeoff in the amount of sunlight that is designed in the summer versus the winter. The undulations may assist in allowing sunlight from lower elevations (winter sunlight) into the building while blocking light at higher elevations (summer sunlight). The webs in the panel 100 act to cover a portion of the aperture at higher inclinations and thus may block greater sunlight in summer than in winter.
To fabricate the panel 100, a continuous sheet of material, such as a metal as described herein, is cut into individual panels 100. The apertures 110 are cut or punched into the interior body portion 109. The outside edge is left whole to form the band 105. If needed, the attachment points are also punched or cut in the area of the band 105. Various methods of cutting can be used, such as water jet, plasma, laser, etc. Thereafter, the panel 100 is placed in a press to form the undulation pattern, e.g., the peaks and valleys, in the entire body 105, i.e., the band 105 and interior body portion 109. In another embodiment, the panel 100 is roll formed after the apertures 110 are punched to form the undulation pattern.
In an example, after the panel 100 is formed the base 152 is fixed to the panel 100. The base 152 is then an integrated part of the panel 100. As such the base 152 is installed at the building site at the same time the panel 100 is installed. This can insure that the base 152 and panel 100 are positioned correctly for illumination of the panel.
Each light source of the lighting system 150 is fixed to the panel 100 or the support system 405. In an example, the same fasteners 413 that fix the panel 100 to support system 405 can be used to fix the light source to the panel. The light source can be positioned at the bottom of each panel and positioned to direct light upwardly onto the respective panel. The light source can further selectively direct light to any of panels connected to the connection point. That is, the light source can illuminate up to four panels that are fixed at the connection point. Moreover, the light source can direct different light to different panels. Accordingly, any individual panel can be illuminated from any direction and with a color that can be the same as from other directions or can be a different color. Each panel can be illuminated with a color different than its neighboring panel(s).
The walkway 410 includes one deck section 421 extending between and fixed to two adjacent braces 407. An end of the deck section 421 extends onto half or less of the top surface of the brace 407 to allow adjacent deck sections to be fixed to the same brace 407. The deck section 421 has a web interior with apertures therethrough to allow moisture, air, and light to pass through the deck section. Various patterns can be used for the web interior of the deck section. Any pattern with apertures therein to allow moisture to travel through the deck section 421 can be used. In another example, a solid deck section is used. The deck sections 421 can further include electrical wiring conduits 460B in which wiring from a power source or a lighting controller to the light sources. In an example, the conduits align with conduits in brackets that extend from the building to the walkway or outwardly to the panel.
In an example, the panel 100 can include an electrical conduit that houses electrical wiring for the lighting system 150. In this example, the lighting system 150 can be integral with the panels 100 such that the lights 151 and required wiring can be installed with the panels and need not rely on special support systems to provide electrical communication with the lighting system.
In the illustrated example, the light 151, which is part of a lighting system 150, includes a base 152 connected to the brace 407. While shown in only one location in
The panel system 400 is shown on only one side of the building, nonetheless, it will be recognized that the panel system can extend around the entire building 501, e.g., all sides. It is desired that the panel system face at least the southern direction to reflect light from the exterior of the building. In another example, the panel system may face the direction that severe weather may impact the building 501. The panel system 400 can extend from the ground to the top of the building 501 in one example. In another example, the panel system 400 does not cover each floor, e.g., the first floor or lower floors may not be covered. Due to the modular nature of the panels 100 in the panel system 400, some panels can be left off and others can be partial panels, here, triangle shaped panels so as not to cover entire floors where it is desired to receive full sunlight. The panels 100 are aligned with windows on the building 501 as well as solid walls to assist in blocking sunlight and keeping the building cool. In an example, the panels 100 can be removed from the support and reversed and reattached. This may extend the life of any coating on the panels 100. In a further example, different coatings can be applied to the two sides of the panel. The panels can be reversed as desired to change the exterior look of the building or the look of the panel system from inside the building.
The lighting system 150 includes a plurality of lights 151, that are set into rows designated by 151A, 151B, 151C, 151D, 151E, 151F, 151G, etc. A first plurality of lights 151 is positioned at the level of the brackets 405. A second plurality of lights 151 are positioned intermediate the brackets 405. A plurality of light columns 521, 522, 523, 524, 525, etc. are provided. As the lights 151 are arranged in rows and columns allows they are individually addressable by a controller (not shown in
The panels systems 400 and 600 are fixed in place, that is, the panels remain in place once installed. The individual panels 100 in the systems 400, 600 are not slidable to control the amount of protection provided by the panel system. Accordingly, the amount of protection and strength of panel is calculated before installation and the panels are manufactured accordingly with a certain gauge of metal, size and shape of apertures, number of apertures, and the pitch of the undulations. The panel system 400 or 600 acts to block some sunlight from the building to assist in reducing cooling costs, while at the same time allowing some sunlight through to enhance the environment for the people working in the building and not require the building to be completely lit by artificial lighting. A light system 150 is provided with lights 151 at the bars 607 or plates 613. In an example, the lights are fixed to the plate 613. While only showed at some plates, it will be understood that each plate 613 can have a light 151 mounted thereto.
As shown in
In a further example, the panels 100 of a system (e.g., 400 or 600) installed on a building are of different dimensions to create different effects and protections to the building. The lighting system 150 can provide different lighting effects that can be controllable. In an example, a plurality of panels 100 has a plurality of heights and widths. In an example, the open areas of different panels (percentage of aperture area as compared to the area of the whole of the panel) are different, e.g., a first group of panels can be solid, and i.e., no open area and other groups of panels can have open areas as described herein. Accordingly, it can be said that a first group of panels has a first property and a second group of panels has a second property. The first property is different from the second property. The differing properties can be finishes as well as size of the panels or size of the apertures.
The light unit 851 can include Light Emitting Diodes (LEDs) to provide illumination of a single panel or a group of panels. LEDs produce light of relatively narrow spectra as a result the bandgap of the semiconductor material used to fabricate the LED. Each light emitter 866, 867, 868 respectively can be red, green, and blue (RGB) LEDs to produce mixed (e.g., white or other colored) light. Slight differences in the relative amounts of each color of the RGB LEDs used in the light unit 851 can emit a color shift in the light by controlling output of each RGB LED. In an example, careful control of spectral content, feedback control mechanisms can be used to ameliorate differences between LEDs in different light units. Such differences may be due to the aging of the LEDs, variations in temperature, or shifts in drive currents, which can occur over the distance from the controller to each light unit positioned adjacent the panels on a building exterior. Moreover, LEDs manufactured by nominally identical processes can have slight variations compared to other LEDs. One example of controlling LEDs can be found in U.S. Pat. No. 7,348,949, which is hereby incorporated by reference for any purpose.
The controller 901 can further include a clock or other timing signal source that can indicate to the controller that the lighting system should be turned on or off. In an example, the controller turns on the lighting system at dusk or shortly after dusk. The memory in the controller can store the time of dusk for each day of the year at the specific latitude whereat the building is positioned. The controller can further load different images based on the day of the week, time of day, time of year, or holidays, etc. This information can be stored in memory. In an example, this information can be updated or downloaded over network 930 from a remote server 940.
Data communication as described in
In an example embodiment, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine may be a server computer, a client computer, a personal computer (PC), a tablet PC, a set-top box (STB), a Personal Digital Assistant (PDA), a cellular telephone, a web appliance, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein.
The example computer system 1100 includes a processor 1102 (e.g., a central processing unit (CPU) a graphics processing unit (GPU) or both), a main memory 1104 and a static memory 1106, which communicate with each other via a bus 1110. The computer system 1100 may further include a video display unit 1110 (e.g., a liquid crystal display (LCD), plasma display, or a cathode ray tube (CRT)). The computer system 1100 also includes an alphanumeric input device 1112 (e.g., a keyboard), a cursor control device 1114 (e.g., a mouse), a drive unit 1116, a signal generation device 1118 (e.g., a speaker) and a network interface device 1120.
The drive unit 1116 includes a machine-readable medium 1122 on which is stored one or more sets of instructions (e.g., software 1124) embodying any one or more of the methodologies or functions described herein. The software 1124 may also reside, completely or at least partially, within the main memory 1104 and/or within the processor 1102 during execution thereof by the computer system 1100, the main memory 1104 and the processor 1102 constituting machine-readable media.
The software 1124 may further be transmitted or received over a network 1126 via the network interface device 1120. While the machine-readable medium 1122 is shown in an example embodiment to be a single medium, the term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” shall also be taken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies shown in the various embodiments of the present invention. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories and optical and magnetic media, and physical carrier constructs.
The covers for the lights 151 are shown as flat plates. It is within the scope of the present invention for the cover to have different shapes. In an example, the cover is a pyramid shape or frusto-conical shape that essentially encloses the light with a window that allows the light to escape the cover to illuminate the panel. Accordingly, the cover directs the light to each specific panel and prevents the light from splashing over on to the adjacent panel.
In a further example, the light 151 is positioned at each corner of each panel. Such a light can illuminate any of the adjacent panels. In the examples herein, the light would illuminate up to four panels. Each direction that the light 151 can illuminate can include its own light source, for example, incandescent bulb or LED or LED system.
The panel and light systems as described herein may also be installed inside buildings or around the exterior of the building to divide the interior space for flow control or security. The lighting system can further be used to communicate information such as directional cues for movement of people in the interior space. Moreover, the use of the presently described panels can be used to emphasize sunlight in some regions of a building such as an atrium or the entryway. This may be useful in region that lack sunlight whereby the amount of sunlight in a particular interior volume of the building can be increased by reflecting the light in a certain direction utilizing the pattern in the panels.
The panel system as described herein can provide an effective shading coefficient of at least 50% and about 54%. By implementing the panel system, an average, annual solar heat gain reduction of greater than 70% can be provided. In some examples, heat gain reduction can be above 80% and has been predicted to be at least 86%. Additional reductions in solar heat gains can be achieved with proper positioning of the walkway which will further shade the remaining sunlight passing through the panels. In some examples, direct sunlight can be prevented from impinging on the building while allowing indirect light to enter the building to provide ambient light. The panel system without the walkway can provide a cooling energy reduction of at least 9% and in a specific example of 9.8%. When the walkway is used, the cooling energy reduction can be at least 10%. In an example with the walkway at floor level the cooling energy reduction is at least about 10.5%. In an example with the walkway at window level the cooling energy reduction is at least about 11.8%. The above numbers are believed to be accurate for a climate that receives significant sunlight, such as a Middle Eastern location, northern Africa location, and other tropical locations between the Tropic of Cancer and the Tropic of Capricorn or subtropical regions that experience a significant amount of direct sunlight. Accordingly, the use of the panel and lighting systems as described herein provide a significant energy reduction and can result in an annual reduction in electricity usage in a range of 4% to 7%. Obviously, the use of such a system is an environmentally beneficial technology.
The above description is intended to be illustrative, and not restrictive. For example, the above-described examples (or one or more aspects thereof) may be used in combination with each other. Other embodiments can be used, such as by one of ordinary skill in the art upon reviewing the above description. The Abstract is provided to comply with 37 C.F.R. §1.72(b), to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. Also, in the above Detailed Description, various features may be grouped together to streamline the disclosure. This should not be interpreted as intending that an unclaimed disclosed feature is essential to any claim. Rather, inventive subject matter may lie in less than all features of a particular disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate embodiment. The scope of the invention should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
