## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation-in-part of application Ser. No. 11/077,186, filed Mar. 10, 2005 (now abandoned), which claimed the benefit of the filing date of U.S. Provisional Application No. 60/551,942, filed Mar. 10, 2004, the entire contents of which are incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to a computer-implemented system for designing luminaires, and more particularly to an environment for designing and submitting orders for luminaires.
BACKGROUND OF THE INVENTION
Customarily, a luminaire is constructed from a number of separate parts, e.g., a base, a pole, and a lamp. Sometimes, the lamp is attached to the pole by one or more arms. A customer can select from a number of choices for each part of the luminaire. Traditionally, a customer selects the parts for the luminaire from a catalog. The customer does not see the actual luminaire until it is assembled.
Luminaires have become increasingly complex, and customer demands have required that a variety of options be made available for customizing the luminaire. In addition to allowing customers to select the basic components of a luminaire such as a base, arm, and shaft, manufacturers may also allow a customer to customize the luminaire by selecting a specific receptacle, cover, arm, banner eyebolt, banner arm, basket holder, street sign, ladder rest, flag holder, internal louver, prismatic glass reflector, finial, material, type of lighting, ballast, shield, voltage, color, fuse, mount, and other options. Height, placement, and orientation of each option may also be customized.
Offering custom luminaires presents several problems. Since a customer does not see the actual luminaire until it has been assembled, the customer may receive an item that he or she did not expect. Further, it may be difficult for a customer to decide what options he or she prefers without seeing the luminaire in the context of the environment in which it will be placed. Further, if a customer places an order over the phone or by fax, mailing, or email, there is an increased likelihood of errors resulting from data entry or miscommunication as well as additional costs associated with manually processing the order.
Therefore, there is a need for a system which can assist a customer in evaluating and customizing the design of a luminaire before submitting an order and that can assist a customer in submitting the order with a decreased likelihood of error.
SUMMARY OF THE INVENTION
In an exemplary embodiment of the present invention, the invention includes a computer implemented system for assisting an operator in designing and customizing a virtual luminaire by selecting options. As the operator selects options, the system may display a sample of that option or a sample of the final luminaire. The system may adjust the options that the operator may select to prevent the operator from selecting incompatible or undesirable combinations of options. The system may also make recommendations for placement of an option or additional options. Additional information such as pricing or inventory data may also be provided. Multiple luminaires may be displayed and customized side by side.
In another exemplary embodiment of the present invention, the invention includes a computer implemented system for assisting an operator in previewing a virtual luminaire in the context of a picture or graphical representation of its surroundings. This may be achieved by displaying a picture or graphical representation with the virtual luminaire placed in it. The virtual luminaire and the background graphic or picture may also be adjusted by the operator for location, size, color, and picture settings.
In yet another exemplary embodiment of the present invention, the invention includes a computer implemented system for assisting an operator in submitting a list of part numbers and options for a luminaire to a manufacturer. This may be achieved by printing an order summary page that lists the selected part numbers, descriptions, and quantities. The order summary page may also be transmitted to a manufacturer or third party by electronic communication such as email or otherwise through a computer network. The operator may provide purchase information or additional information to accompany the order information.
In one aspect of the invention, an apparatus allows designing luminaires from sets of interchangeable parts such that one part from each set fits with one part from each of the other sets to form a complete luminaire: the apparatus includes a display device having a screen, a memory for storing images of the parts, a microprocessor programmed to display the stored images, and an input device for selecting one part from each set required to form a complete luminaire. The microprocessor is programmed to assemble on the screen the complete luminaire from the selected parts.
In another aspect of the invention, a system allows designing and ordering luminaires: the system includes a user interface including a display for selecting parts of a luminaire from different designs and for displaying a luminaire composed of the selected parts and a copy buffer capable of storing copies of the luminaire, usable for incorporating the luminaire into a document or file that can be printed or submitted electronically.
In yet another aspect of the invention, a method allows designing luminaires from sets of interchangeable parts such that one part from each set fits with one part from each of the other sets to form a complete luminaire: the method includes receiving input via an interface, the input representing a selection of interchangeable parts, displaying the complete luminaire or a partially complete luminaire composed of the selection of interchangeable parts, and storing the complete luminaire or the partially complete luminaire for the purpose of incorporating the complete luminaire or the partially complete luminaire into a document or a file that can be printed or submitted electronically.
In yet another aspect of the invention, a computer program product recorded on a computer readable medium allows designing luminaires from sets of interchangeable parts such that one part from each set fits with one part from each of the other sets to form a complete luminaire: the computer program product includes computer readable program code with a software interface for receiving input, the input representing a selection of interchangeable parts, computer readable program code for displaying the complete luminaire or a partially complete luminaire composed of the selection of interchangeable parts, and computer readable program code for storing the complete luminaire or the partially complete luminaire for the purpose of incorporating the complete luminaire or the partially complete luminaire into a document or a file that can be printed or submitted electronically.

DETAILED DESCRIPTION
FIG. 1 depicts the opening screen displayed when the system disk is installed in the drive of a computer that is running the program described below. In the opening screen, the user can select where to start the process of designing a virtual luminaire.
FIGS. 2 to 14 illustrate the flow in operating the system. FIGS. 15 to 46 depict the on-screen displays generated by the system disk. The on-screen displays of FIGS. 15 to 45 all have certain common features. The individual available parts are displayed in a large field 1500 on the left side of the screen and the selected parts are displayed in a large field 1502 on the right side of the screen.
Referring to FIG. 2, the customer provides input to the lighting post luminaire section of the system by selecting the desired components and options. As part of the lighting post section, the customer may select a base, shaft, arms, and luminaire. The options and components may be presented to the operator in a variety of formats or displays. In the exemplary embodiment shown in FIG. 2, a series of menus, including icons representing the components is shown to the customer. In addition to selecting icons, a customer may enter data manually, such as a shaft height. As the customer selects the components and options, a virtual luminaire is displayed on the screen. A novice operator of the system may build a virtual luminaire with ease by following the on screen instructions. An advanced operator may jump through the program to provide greater flexibility. For example, an operator may, at any time, print the current screen, display order information, save information, toggle the background, open instructions for saving the document, exit the program, modify the colors, modify the background, transform the image, or manually enter specifications.
FIGS. 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 14 show how a customer may select other features of a luminaire in a similar way as FIG. 2 shows the selection of the lighting post.

Referring back to FIG. 4, the flow diagram shows steps for selecting a pier mount luminaire. As a first step the pier mount portion of the pier mount luminaire is selected and displayed as shown by the “chose pier mount” display step 402. A possible set of designs for the pier mount portion and an according user interface and display are shown in FIG. 30. Then, similarly to the lighting post luminaire flow diagram of FIG. 2, FIG. 4 shows the steps of choosing arms 404, including an “execute arms” subsection 406 referring to the flow diagram of FIG. 6 already described above in the context of selecting arms for the lighting post luminaire. Finally, the luminaire portion of the pier mount luminaire is chosen, as indicated by the “choose a luminaire” display 408. A possible selection of luminaire portions including an according interface and display is shown in FIG. 31. Again, selection of a luminaire portion includes selection of luminaire options as indicated in the step “user selects luminaire options” 410 of the flow diagram in FIG. 4. A possible selection of options including an according interface and display is shown in FIG. 32.
Once the complete pier mount luminaire is selected, the embodiment of FIG. 4 allows for selection of a number of global options including display of order information 412. One such possible display is shown in FIG. 33.
Referring back to FIG. 8, the flow diagram shows steps for selection a wall mount luminaire. First, a wall bracket is selected, as indicated by the “choose wall bracket” display 802. A possible set of designs of wall brackets and an according interface and display are shown in FIG. 34. Then, the luminaire portion of the wall mount luminaire is selected, beginning at the “choose luminaire” display step 804. As before, such selection includes selection of luminaire options 806. A possible set of options and an according user interface and display is shown in FIG. 35.
Once the complete wall mount luminaire is selected, the embodiment of FIG. 8 allows for selection of a number of global options including display of order information 808. One such possible display is shown in FIG. 36.
Referring back to FIG. 9, the flow diagram shows steps for selecting a bollard luminaire. In this particular embodiment, selecting the bollard 902 is the main step of the process. A possible set of designs and an according interface and display are shown in FIG. 37. Choosing a bollard is followed by selecting bollard options 904. A possible set of options and an according interface and display is shown in FIG. 38.
Once the complete bollard luminaire is selected, the embodiment of FIG. 9 allows for selection of a number of global options including display of order information 906. One such possible display is shown in FIG. 40.
This particular embodiment of the invention also allows for accelerated selection via entry of part numbers rather than visual selection. This feature is called “manual build.” FIG. 39 shows a “manually built” bollard via entry of its part number “blcl-hcap” 3902. FIG. 7 shows a flow diagram outlining the steps of the “manual build” feature. FIG. 10 and FIG. 11 show the steps of the “manual build” feature when selecting a wall mount or ceiling mount, respectively.
After one or more luminaires are selected, their parts may be changed or moved, i.e. transformed, further luminaires may be added, or selected luminaires may be deleted. FIGS. 41, 42, 43 and 44 show possible interfaces and displays for transforming parts, assigning them to selected luminaires, and adding and deleting luminaires.
FIG. 41 shows controls for selecting sites within which luminaires may be displayed 4102, 4104. The operator can choose between using his or her own images of sites 4102 or selecting from a stock of photographs provided by the system 4104. FIG. 42 and FIG. 43 show controls for adding and removing items 4202, 4302, selecting luminaire units, 4304, positioning 4206, 4306 and scaling 4208, 4308 them and other controls. FIG. 44 shows controls for selecting colors for individual parts. A flow diagram outlining the process of color selection is shown in FIG. 14.
Once one or more luminaires have been selected, possibly transformed and scaled and optionally put into the context of a site, the system allows for storing the information usable for printing and/or electronic submission.
FIG. 45 shows instructions 4502 for saving in a Microsoft Word document order information 4504 for the design of a selected luminaire and transmitting the selected design to a luminaire seller or manufacturer. Also shown aside of order information 4504 are a background image 4506 and a set of selected luminaries 4508 projected into background image 4506. The background image including the selected luminaries could be a perspective view of a site selected for installation of luminaries 4508, as shown, or a plan view. Background image 4506 is created, for example, by taking a photograph of the selected site or by using a preexisting representation of the selected site from a brochure or the like. This photograph or preexisting brochure is scanned, formatted, and loaded into a memory 14 for use in creating an on-screen display. Memory 14 is described further below in connection with FIG. 46.
FIG. 46 shows a computer for implementing the described operations and on-screen displays. An input device 10 such as a mouse or keyboard is connected to a microprocessor 12. Microprocessor 12 exchanges data with a memory 14 in which electronic files are stored. For example, the files could comprise a collection of different bases, a collection of different poles, a collection of different arms, a collection of different lamps, and accessories for the luminaries. The files are preferably images of the various parts adapted to fit together to form a virtual luminaire. Microprocessor 12 is programmed to carry out the steps described in FIGS. 2 to 14 and present the on-screen displays shown in FIGS. 15 to 44.
Specifically, the customer is led through the selection process by icons and text boxes on the screen of display 16. Other files could represent this data. At each step, the customer uses input device 10 to select one of the images representing parts shown on the screen. Microprocessor 12 could be programmed to limit the parts from one file that can be combined with parts from another file. For example, a pole may have a smaller or larger diameter than the base socket into which the pole fits. In such case, microprocessor 12 will not permit this combination of parts. A customer can select options to design and display a virtual luminaire. In this way the customer can easily create and change the design without having to build the luminaire.
Microprocessor 12 is programmed to superimpose the selected virtual luminaire on the selected background and change the size of the image to fit the background. A click and drag maneuver could be used to superimpose the virtual luminaire at the desired position on the background. A number of copies of the virtual luminaire could be superimposed on the background. If a perspective view is desired the sizes of successive copies are gradually reduced in sequence to give a three dimensional appearance to the image. Further, a color palette could be represented on the screen. To select a desired color for the virtual luminaire the customer simply clicks on the desired color swatch of the palette and the virtual luminaire assumes this color.
The microprocessor is also programmed to generate a purchase order (PO) from the customer selection. The PO is represented on the screen for editing, making a hard copy on a printer 18, and transmission to the manufacturer.
The relationship between the flow diagrams of FIGS. 1 to 14 and the on-screen displays is as follows:
