Apparatus and related methods relate to lighting devices with built-in status displays. In an illustrative example, a multi-mode programmable indicator light (MPIL) may include at least one embedded programmable scrolling display (EPSD) at one or more light emitting portions (LEPs) of the MPIL. The LEP may, for example, emit a light marker in a first plane orthogonal to a longitudinal axis of the MPIL. The EPSD may, for example, display a predetermined scrolling message at a physical peripheral boundary of the MPIL.

[0018] Various embodiments generally relate to configurable visual indicators.

[0019] background

[0020] For decades, single-color and multi-color indicators have been used to indicate machine status or process status. Typically, the color of an indicator can convey a predetermined meaning (e.g., machine status or process status) to alert workers, machine operators, and / or supervisors. For example, a typical stack light can be used with a standard for the meaning of each color. For example, according to the standard, a red light may mean an emergency, an amber light may mean an abnormal observation, a green light may represent normal operation, and a blue light may mean that enforcement action is required.

[0021] As technology advances, more colors can be used as indicators. In some examples, flashing lights can be used to indicate machine or process status. To communicate the meaning of these new colors and / or patterns, a legend plate can be used to display the meaning directly next to each indicator light to give the operator guidance on the meaning of the indicator light (illumination).

[0022] Overview

[0023] Apparatus and related methods relate to lighting devices with built-in status displays. In an illustrative example, a multi-mode programmable indicator light (MPIL) may include at least one embedded programmable scrolling display (EPSD) at one or more light emitting portions (LEPs) of the MPIL. The LEPs may, for example, emit a light marker in a first plane orthogonal to the longitudinal axis of the MPIL. The EPSD may, for example, display a predetermined scrolling message at the physical peripheral boundary of the MPIL. The scrolling message may, for example, represent a corresponding predetermined interpretation of the light marker. For example, the scrolling message may be displayed in a second plane substantially parallel to the first plane. Various embodiments may advantageously display the interpretation of the light marker from substantially 360° around the longitudinal axis of the MPIL.

[0024] Various embodiments may achieve one or more advantages. For example, some embodiments may display multiple messages in different parts of the MPIL to advantageously provide multiple messages simultaneously. For example, some embodiments may provide a 360° viewing angle without multiple legends around the MPIL. For example, some embodiments may include a user interface to advantageously provide an MPIL that is easy to program / reprogram. For example, some embodiments may advantageously provide multiple combinations of background color, text color, character height and / or brightness of the EPSD to enhance color adaptation for color blind people. For example, some embodiments may include a packaging shell to advantageously protect the MPIL from (potentially) harsh operating environments. For example, some embodiments may be flexible to advantageously provide a peripheral optical boundary.

[0025] The details of various embodiments are set forth in the drawings and the description that follows. Other features and advantages will be apparent from the description and drawings, and from the claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0035] Figure 1 An exemplary multi-mode programmable indicator light (MPIL 100) employed in an illustrative use case scenario is depicted. In the depicted example, a factory 105 includes a plurality of MPILs 100. For example, the MPILs 100 may be attached to machines 115 in the factory 105. For example, the lighting indicators may include a single-color indicator or a multi-color indicator (e.g., a factory tower light) for indicating a machine state or a process state. For example, a worker in the factory 105 may read a status signal transmitted by the MPIL 100 and interpret the state of the machine 115 (e.g., the machine is in good working order, the machine requires maintenance, the machine has a safety issue). In some examples, each of the colors of the lighting indicators may be generally assigned a meaning for conveying and / or alerting a machine operator or floor supervisor.

[0036] like Figure 1 As shown in the close-up view in FIG. 1 , the MPIL 100 may include one or more light emitting portions (LEP 110a, LEP 110b, LEP 110c). For example, each of LEP 110a-LEP 110c may be a segment of a stacked tower light. For example, the top LEP 110a may be configured to display red light. For example, the middle LEP 110b may be configured to display amber light. For example, the bottom LEP 110c may be configured to display green light. As shown, the MPIL 100 extends along a longitudinal axis y. In some embodiments, LEP 110a-LEP 110c may display light 360° around the longitudinal axis y in a first plane p1.

[0037] In some embodiments, LEP 110a-LEP 110c may be a reconfigurable light emitting diode (LED) circuit. For example, the reconfigurable LED circuit may be reconfigured in size and color so that LEP 110a-LEP 110c may be selectively varied in height and color. In some examples, MPIL 100 may be configured to a specific configuration controlled by a control signal connected to MPIL 100. For example, LEP 110a may be configured to flash red when MPIL 100 receives a corresponding control signal.

[0038] In this example, LEP 110a includes an embedded programmable scrolling display (EPSD 120). In some implementations, EPSD 120 can be configured to display text indicating the meaning (of the color) of the corresponding LEP (eg, LEP 110a).

[0039] As shown, the EPSD 120 is configured to display a message indicating that the LEP 110a (e.g., a red illuminated indicator) means "DANGER". For example, the message may surround the perimeter of the LEP 110a. In some embodiments, more than one message may be displayed at any one of the LEPs 110a-LEP 110c. For example, the message may be a repeating pattern distributed around an axis (e.g., the y-axis). For example, the LEP 110a may include one message at the bottom and another message at the top to advantageously provide multiple messages for each segment of the MPIL 100. In the depicted example, the message may scroll around the longitudinal axis y in a second plane p2. In some embodiments, the plane p1 and the plane p2 are coplanar. Thus, for example, the MPIL 100 may advantageously provide a 360° viewing angle without multiple legends surrounding the multi-color MPIL 100.

[0040] In the depicted example, MPIL 100 includes MPIL controller 125. In some implementations, MPIL 100 can include one or more RGB LEDs on a control circuit (e.g., a vertical printed circuit board (PCB)). For example, the RGB LEDs can be configured to display a variety of color combinations controlled by a controller running control software. In some implementations, by programming MPIL controller 125, the LEP can be configured to selectively display a status message corresponding to the color of the LEP.

[0041] In this example, a user may use a computing device 155 to configure MPIL 100. For example, computing device 155 may be a desktop computer. For example, computing device 155 may be a mobile computing device. In some examples, computing device 155 may be a server accessed by a user device via a network (Internet). In this example, computing device 155 includes a tower light programming module (TLPM 130). For example, TLPM 130 may be executed by computing device 155 to program MPIL 100. In this example, TLPM 130 may display a user interface 135 for a user to selectively input configurations to MPIL 100.

[0042] In some embodiments, EPSD 120 can be programmed to display a message representing the interpretation of the corresponding LEP 110a-LEP 110c. As shown, user interface 135 can be used to program the first portion (of red light) of MPIL 100. The user can select a predetermined message associated with the first portion (red light) from a drop-down menu 140. For example, the predetermined message can be associated with the meaning of the LEP. In some examples, the predetermined message can be built into TLPM 130. In some examples, new messages can be selectively added by the user via user interface 135. In some embodiments, various parameters associated with the meaning can be selected. For example, the message can be programmable through user interface 135. As shown, the user can use selection box 145 to select the text size. In some embodiments, the user can use TLPM 130 to configure the background color, text color, character height and / or brightness of EPSD 120. For example, the message can be static or scroll at a user-selectable speed. For example, messages in multiple languages ​​can be displayed. Thus, the TLPM 130 may advantageously provide an easy programming / reprogramming interface and enhance color adaptation for color blind persons.

[0043] In some embodiments, the TLPM 130 can generate a configuration data structure (CDS 150). In some embodiments, the CDS 150 can include a configuration schema that can be read by the MPIL controller 125. For example, the configuration schema can include, for example, a mapping between a message and one or more of the LEPs. For example, the configuration schema can include a mapping between an input signal and a color and / or operating characteristic (e.g., animation, brightness) of one or more of the LEPs.

[0044] In the depicted example, the CDS 150 may be transmitted to the MPIL 100 to configure display messages at one or more of the LEPs 110a-110c based on user input. For example, the CDS 150 may be flashed into a memory device (e.g., an onboard data register) of the MPIL 100. In some examples, the CDS 150 may be transmitted to the MPIL 100 via a network communication module (NCM) that is operably coupled to the MPIL controller 125 via a communication network. As an illustrative example, the NCM may be configured to interact with a Modbus network. In some examples, the NCM may be configured to interact with a Banner bus network (e.g., specified by Banner Engineering Corp., Plymouth, MN). In some examples, the NCM may be configured to interact with an IOLink network.

[0045] In various embodiments, the MPIL 100 may extend along the y-axis and define a physical peripheral boundary path in a first plane p1 orthogonal to the y-axis. For example, the MPIL 100 may emit a light mark (e.g., a static light) corresponding to a predetermined interpretation in p1. For example, the EPSD 120 may be substantially arranged along the physical peripheral boundary path of the MPIL 100. For example, when the MPIL 100 emits the light mark, the EPSD 120 may display at least one predetermined text message in a second plane p2 parallel to p1. For example, the at least one predetermined text message represents a corresponding predetermined interpretation of the light mark, so that the at least one visual mark is visible in p2 from substantially 360° around the y-axis.

[0046] Figure 2 is a block diagram depicting an exemplary MPIL controller 125. In the depicted example, the MPIL controller 125 includes a processor 205. The processor 205 may, for example, include one or more processing units. The processor 205 is operably coupled to a communication module 210. The communication module 210 may, for example, include wired communication. The communication module 210 may, for example, include wireless communication. The communication module 210 may, for example, include MODBUS communication. In the depicted example, the communication module 210 is operably coupled to a computing device 155 and a central controller 215. For example, the computing device 155 may be configured to receive a CDS 150 transmitted to the communication module 210. For example, the central controller may transmit a control signal corresponding to a state change in the plant 105 to the MPIL 100. For example, when an emergency is detected, the central controller 215 may transmit a control signal to display an emergency light at the MPIL 100.

[0047] The processor 205 is operably coupled to a memory module 220. The memory module 220 may, for example, include one or more memory modules (e.g., random access memory (RAM)). The processor 205 includes a storage module 225. The storage module 225 may, for example, include one or more storage modules (e.g., non-volatile memory). In the depicted example, the storage module 225 includes a device programming engine (DPE 230) and a device operation engine (DOE 235).

[0048] For example, DPE 230 may process CDS 150 received from computing device 155. In some implementations, DPE 230 may identify a mapping between LEPs (e.g., LEPs 110a-110c) and corresponding visual indicia (e.g., textual interpretations) based on CDS 150. For example, DPE 230 may retrieve the mapping and display the visual indicia with the corresponding LEPs. In some examples, DPE 230 may operate based on control signals received from central controller 215.

[0049] The processor 205 is also operatively coupled to a data store 245. As shown, the data store 245 includes a predetermined association database 250, predetermined display profiles 255, and a predetermined visual marker database 260. In some embodiments, the predetermined association database 250 may store predetermined associations between the respective LEPs 110a-110c and the corresponding interpretation displays (e.g., text). For example, after receiving the mapping, the DPE 230 may store the associations indicated in the mapping in the predetermined association database 250.

[0050] In some embodiments, the predetermined display profile 255 may include display parameters of the visual indicia at the LEP 110a-LEP 110c. For example, the display parameters may include a font size of a text message. For example, the display parameters may include a color of a text message. In some embodiments, the display parameters may indicate a display mode of the visual indicia. For example, the display profile may include a stealth mode and an operating mode for the visual indication. For example, in the stealth mode, the visual indicia may be configured to be a solid color that is substantially the same as the color of the corresponding portion of the MPIL 100. For example, in the operating mode, the visual indicia may include a background that is different from the corresponding portion of the MPIL 100 and a scrolling text message.

[0051] For example, the predetermined visual indicia database 260 may include various visual indicia corresponding to the LEP. For example, in operation, the DOE 235 may retrieve a visual indicia corresponding to the LEP from the predetermined visual indicia database 260. For example, the DOE 235 may display the retrieved visual indicia based on display parameters indicated in the predetermined display profile 255 associated with the visual indicia.

[0052] Figure 3A and Figure 3B An exemplary embodiment of a MPHIL is depicted. Figure 3A An MPIL 300 with an EPSD 305 in a multi-color stacked light application is shown. As shown, the EPSD 305 includes built-in images. In some embodiments, the built-in images can be pre-installed in the MPIL 300. In some embodiments, the built-in images can be user programmable. For example, the MPIL 300 can include a message at the bottom or top of multiple messages (one for each segment).

[0053] As shown, the MPIL 300 can extend along the y-axis and define a first peripheral boundary path 310 orthogonal to the y-axis. In this example, the MPIL 300 emits a static light marker (e.g., a red light) in the top LEP 315 of 300. The EPSD 305 can display a text message 325 substantially along a second peripheral boundary path 330 of the MPIL 300. For example, the EPSD 305 can display the text message 325 in the second peripheral boundary path 330 that is parallel to the first peripheral boundary path 310. For example, the text message 325 can be visible from substantially 360° around the y-axis along the second peripheral boundary path 330. For example, the text message 325 can be a repeating pattern distributed around an axis (e.g., the y-axis).

[0054] Figure 3B The MPIL 350 in a single indicator application with the EPSD 355 is shown. For example, the background color and foreground color of the MPIL 350 can be electrically changed by using an RGB LED. In this example, the EPSD 355 includes a built-in image wrap function around the perimeters 370a, 370b of the MPIL 350. As shown, the perimeters 370a and 370b can be parallel. For example, the perimeters 370a, 370b can be orthogonal to the y-axis. For example, the built-in image displayed at the EPSD 355 can be scrolling. For example, the built-in image can be static.

[0055] In various embodiments, the EPSD 305, EPSD 355 can be fully configurable by software (e.g., TLPM 130), including background color, text color, character height, and brightness. In some examples, the EPSD 305, EPSD 355 can scroll at a user-selectable speed. In some embodiments, multiple images can be stored and linked to various inputs at the segments of the MPIL 300.

[0056] like Figure 3B As shown, EPSD 355 can be located inside housing 360, for example, together with the illuminated indicator of MPIL 350. For example, EPSD 355 can be advantageously protected from the external environment (which can be harsh to EPSD 355). In some examples, Figure 3A The MPIL 300 may also include a single housing that encapsulates both the EPSD 305 and the RGB LEDs of the multi-color stack lamp.

[0057] As shown, the housing 360 can be coupled to the base housing 365. For example, the base housing 365 can include electrical connections and communication connections for the MPIL 350. As shown, the housing 360 extends substantially parallel to the physical peripheral boundary path of the EPSD 355. In some embodiments, the housing 360 can be at least partially optically transparent. For example, a built-in image displayed at the EPSD 355 can be visible through the housing 360. In some embodiments, the housing 360 can be configured to apply a predetermined optical effect to the indicator light and / or the built-in image within the MPIL 350.

[0058] Figure 3C Describes (such as in Figure 3B 395 (e.g., a wire, bus, cable). For example, the control circuit 385 can provide control signals and / or power to the individual light emitters 380 via the leads 395 and the EPSD 355.

[0059] As depicted, EPSD 355 and control circuit 385 are coupled (e.g., mounted) to base element 390. Base element 390 can, for example, provide a structure. In some embodiments, base element 390 can, for example, be a printed circuit board. For example, control circuit 385 can be formed directly on base element 390.

[0060] In the depicted example, the EPSD 355 is disposed around the perimeter of the base element 390 such that the EPSD 355 is disposed around the perimeter boundary of the EPSD 355. In some embodiments, by way of example and not limitation, the EPSD 355 can, for example, be rigidly formed into the shape of the perimeter. In some embodiments, by way of example and not limitation, the EPSD 355 can, for example, be joined (e.g., multi-segmented) such that the EPSD 355 can be disposed around the perimeter. In some examples, the EPSD 355 can be flexible (e.g., a flexible circuit having at least one flexible substrate such that it can be manually manipulated into a series of desired curved shapes). Thus, the EPSD 355 can advantageously provide a peripheral optical boundary. For example, the EPSD 355 can be at least partially opaque.

[0061] In the depicted example, housing 360 is disposed around the exterior of EPSD 355. Housing 360 can, for example, be optically transparent. In some implementations, housing 360 can apply one or more optical effects (eg, increased refraction and / or reflection, frequency filtering).

[0062] In some embodiments, one or more lighting modules (e.g., light bulbs, LEDs) can be disposed above the EPSD 355 relative to the longitudinal axis. In some embodiments, one or more lighting modules can be disposed within the EPSD 355, but configured such that light is emitted above and / or below the EPSD 355 relative to the longitudinal axis. In some such embodiments, the EPSD 355 can provide, for example, a dynamic interpretation of light displayed longitudinally adjacent to the EPSD 355.

[0063] Figure 4 4 is a flow chart illustrating an exemplary indicator light programming method 400. For example, the DPE 230 may execute the method 400 to associate various predetermined visual indicia with corresponding LEPs of the MPIL. The method 400 begins at step 405 when a data object configuring one or more portions of the MPIL is received from a user device. For example, the MPIL controller 125 may receive the CDS 150 from the computing device 155. Next, in step 410, parameters (e.g., text, scroll speed, text color) including the visual indicia and the configuration of at least one associated LEP are determined from the data object. In step 415, an association between the LEP and the visual indicia is generated. After the association is generated, in step 420, the generated association is stored in a first data repository (e.g., the predetermined association database 250). In step 425, the parameters associated with the visual indicia are stored in a second data repository (e.g., the predetermined display profile).

[0064] At decision point 430, it is determined whether the visual marker is newly defined. For example, the visual marker may be a new meaning of the LEP defined by the user. If it is determined that the visual marker is not newly defined, the method 400 ends. If it is determined that the visual marker is newly defined, then in step 435, the new visual marker is stored to a third data repository (e.g., a predetermined visual marker database), and the method 400 ends.

[0065] Figure 5is a flow chart illustrating an exemplary indicator light operation method 500. For example, the DOE 235 may use the method 500 to control the MPIL 100 in operation. The method 500 begins when an input signal to operate the MPIL is received in step 505. For example, the control signal is received from the central controller 215. At decision point 510, it is determined whether the input signal corresponds to any stored predetermined associations. For example, the predetermined association database 250 may include a mapping between the input signal and the corresponding display of the MPIL 100. If the input signal does not correspond to any stored predetermined association, the method 500 ends.

[0066] If the input signal corresponds to a stored predetermined association, then in step 515, a light indicia (e.g., LEP) and at least one predetermined visual indicia (e.g., scrolling text) are retrieved from a data repository based on the input signal. In step 520, the MPIL is operated to display the light indicia. For example, the DOE 235 may retrieve a color associated with the input signal from the predetermined display profile 255. In step 525, the MPIL is operated to display the visual indicia, and the method 500 ends. For example, the DOE 235 may retrieve a corresponding text message associated with the light indicia to be displayed from the predetermined visual indicia database.

[0067] Although various embodiments have been described with reference to the drawings, other embodiments are possible.

[0068] Although referenced Figure 1 An exemplary system is described, but other embodiments may be deployed in other industrial, scientific, medical, commercial, and / or residential applications.

[0069] In various embodiments, some bypass circuit implementations may be controlled in response to signals from analog or digital components, which may be discrete, integrated, or a combination of each thereof. Some embodiments may include a programmed device, a programmable device, or some combination thereof (e.g., a PLA, a PLD, an ASIC, a microcontroller, a microprocessor), and may include one or more data storage devices (e.g., cells, registers, blocks, pages) that provide single-level or multi-level digital data storage capabilities and may be volatile, non-volatile, or some combination thereof. Some control functions may be implemented in hardware, software, firmware, or any combination thereof.

[0070] A computer program product may include a set of instructions that, when executed by a processor device, causes the processor to perform specified functions. These functions may be performed in conjunction with a controlled device in operable communication with the processor. A computer program product, which may include software, may be stored in a data storage device tangibly embedded on a storage medium, such as an electronic, magnetic, or rotating storage device, and may be fixed or removable (e.g., hard disk, floppy disk, thumb drive, CD, DVD).

[0071] Some systems may be implemented as computer systems that may be used in various embodiments. For example, various embodiments may include digital circuits, analog circuits, computer hardware, firmware, software, or a combination thereof. The apparatus may be implemented in a computer program product that is tangibly embodied in an information carrier, such as a machine-readable storage device, for execution by a programmable processor; and the method may be executed by a programmable processor executing an instruction program to perform the functions of the various embodiments by operating on input data and generating output. Various embodiments may advantageously be implemented in one or more computer programs that may be executed in a programmable system that includes at least one programmable processor coupled to receive data and instructions from and transmit data and instructions to a data storage system, at least one input device, and / or at least one output device. A computer program is a set of instructions that may be used directly or indirectly in a computer to perform a specific activity or produce a specific result. The computer program may be written in any form of programming language, including compiled or interpreted languages, and the computer program may be deployed in any form, including as a stand-alone program or as a module, component, subroutine or other unit suitable for use in a computing environment.

[0072] As an example, suitable processors for executing instruction programs include both general-purpose microprocessors and special-purpose microprocessors, which may include a single processor or one of multiple processors of any type of computer. Typically, the processor receives instructions and data from a read-only memory or a random access memory or both. The key elements of a computer are a processor for executing instructions and one or more memories for storing instructions and data. Typically, a computer will also include one or more mass storage devices for storing data files, or be operably coupled to the one or more mass storage devices to communicate with them; such devices include disks, such as internal hard disks and removable disks; magneto-optical disks; and optical disks. Storage devices suitable for tangibly embodying computer program instructions and data include all forms of non-volatile memory, including, as an example, semiconductor memory devices, such as EPROM, EEPROM, and flash memory devices; disks, such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.

The components of the system can exchange information through analog or digital data communication of any form or medium, including packet-based messages on a communication network. Examples of communication networks include, for example, a LAN (local area network), a WAN (wide area network), a MAN (metropolitan area network), a wireless network and / or an optical network, computers and networks forming the Internet, or some combination thereof. Other embodiments can transmit messages by broadcasting to all or substantially all devices connected together by a communication network, such as by using omnidirectional radio frequency (RF) signals. Still other embodiments can transmit messages characterized by high directivity, such as RF signals transmitted using directional (i.e., narrow beam) antennas or infrared signals that can optionally be used with focusing optics. Other implementations are possible using appropriate interfaces and protocols, such as, by way of example but not limitation, USB 2.0, Firewire, ATA / IDE, RS-232, RS-422, RS-485, 802.11a / b / g, Wi-Fi, Ethernet, IrDA, FDDI (Fiber Distributed Data Interface), Token Ring, multiplexing techniques based on frequency division, time division or code division, or some combination thereof.
