Description

[Technical Field]

[0001] The present invention relates to a multi-channel lighting power supply device that can be connected to a plurality of illuminators and can supply power to each illuminator in an individual manner. [Background technology]

[0002] For example, an inspection lighting system used for visual inspection of products includes multiple illuminators and a multi-channel lighting power supply device that can supply power to each illuminator in an individual manner so that the multiple illuminators can emit light at different times and cycles (see Patent Document 1).

[0003] Some such lighting power supplies not only have multiple channels to which multiple illuminators are respectively connected, but also have multiple input connectors through which command signals such as trigger signals are input from the outside to any of the illuminators, and multiple output connectors that output the command signals input from the input connectors to the outside. For example, a trigger signal output from an output connector is used to synchronize the light emission timing of the illuminators with the shutter timing of a camera.

[0004] Although numbers are assigned to each input connector, channel, and output connector to identify them, the connection relationships between them are not fixed even if the same numbers are assigned, and the combinations can be set arbitrarily. For example, by changing the settings, it is possible to output a trigger signal input to input connector 1 from channel 2 or 3 instead of channel 1.

[0005] In this way, the combination of the correspondence between input connectors, channels, and output connectors can be freely changed, so restrictions on wiring, for example, can be reduced, making it easier to update the lighting equipment.

[0006] However, because the correspondence between the signals can be freely set, it can be difficult for the user to understand the trigger signal assignment settings, such as which channel the trigger signal input to the input connector will be input to, which connected illuminator, and which camera's shutter will be released via the output connector. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 6806372 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a lighting power supply that can freely assign to which of a plurality of connected lighting devices a command signal input to an input connector is to be output, and that allows the user to easily grasp the correspondence between these signals. [Means for solving the problem]

[0009] That is, the lighting power supply device according to the present invention is a multi-channel lighting power supply device, comprising: a setting management screen display unit that displays a setting management screen configured to be switchable between a setting mode and a confirmation mode, the setting management screen including a plurality of channels to which a plurality of illuminators are respectively connected individually; a plurality of input connectors to which a command signal for controlling at least one of the plurality of illuminators is input from outside; a plurality of illuminator icons respectively representing the plurality of illuminators; and a plurality of input connector icons respectively representing the plurality of input connectors, the setting management screen display unit comprising: an assignment setting receiving unit that receives a user's selection of one of the plurality of input connector icons on the setting management screen in the setting mode and a combination of one or more selected illuminator icons as an assignment setting that assigns a command signal to be input to the input connector corresponding to the selected input connector icon to be used to control the illuminator corresponding to the selected illuminator icon; an assignment memory unit that stores the accepted assignment setting; and a correspondence display unit that, when a user selects one of the plurality of input connector icons on the setting management screen in the confirmation mode, changes a display mode of the illuminator icon associated with the selected input connector icon on the setting management screen based on the stored assignment setting.

[0010] With this configuration, the user can easily assign a command signal input to any input connector to the control of any illuminator simply by selecting an input connector icon or an illuminator icon on the setting management screen in the setting mode. Also, when the user selects an input connector icon on the setting management screen in the confirmation mode, the correspondence display unit changes the display mode of the illuminator icon corresponding to the illuminator to which the command signal will be assigned based on the assignment setting, so that the user can easily understand the assignment setting between multiple input connectors and multiple illuminators.

[0011] In order to make it easier for a user to understand not only the assignment settings between a plurality of input connectors and a plurality of illuminators but also the assignment settings when a command signal input to an input connector is assigned to a device other than the illuminators, the system may further comprise a plurality of output connectors for outputting a command signal input to any of the plurality of input connectors to devices other than the plurality of illuminators, and the setting management screen display unit is configured to display on the setting management screen a plurality of output connector icons each indicating the plurality of output connectors, and the assignment setting receiving unit is configured to receive a user's selection of one of the plurality of input connector icons on the setting management screen in the setting mode and a display of one or more of the plurality of illuminator icons or the plurality of output connector icons. The correspondence display unit may be configured to accept a combination of selected numbers as the assignment setting that assigns a command signal to be input to an input connector corresponding to a selected input connector icon to be used to control an illuminator corresponding to a selected illuminator icon, or to be output from an output connector corresponding to a selected output connector icon, and when a user selects one of the plurality of input connector icons on the setting management screen in the confirmation mode, change the display mode of the illuminator icon or the associated output connector icon on the setting management screen based on the stored assignment setting.

[0012] To make it easier for the user to understand the correspondence with all devices related to the allocation setting, the correspondence display unit may be configured to change the display mode of the selected input connector icon on the setting management screen.

[0013] A specific example of a configuration that makes it easy for a user to understand which illuminator or output connector is being linked to an input connector when the user performs assignment settings is one in which the setting management screen display unit is configured to change the display mode of the input connector icon, illuminator icon, or output connector icon selected by the user on the setting management screen in the setting mode.

[0014] A specific example of the command signal is one in which the command signal input to the input connector is a trigger signal.

[0015] In order to obtain the same effects as the lighting power supply device of the present invention by updating a program in an existing lighting power supply device, a program for use in a multi-channel lighting power supply device having a plurality of channels to which a plurality of illuminators are individually connected and a plurality of input connectors to which a command signal for controlling at least one of the plurality of illuminators is input from outside is provided, the program including a setting management screen display unit that displays a setting management screen that includes a plurality of illuminator icons respectively representing the plurality of illuminators and a plurality of input connector icons respectively representing the plurality of input connectors, and is configured to be switchable between a setting mode and a confirmation mode; and a setting management screen display unit that displays a setting management screen that includes a plurality of illuminator icons respectively representing the plurality of illuminators and a plurality of input connector icons respectively representing the plurality of input connectors, the setting management screen being switchable between a setting mode and a confirmation mode. It is sufficient to use a lighting power supply program that causes a computer to function as an assignment setting receiving unit that receives one or a combination of selected illuminator icons as an assignment setting that assigns a command signal input to an input connector corresponding to a selected input connector icon to be used to control the illuminator corresponding to the selected illuminator icon; an assignment memory unit that stores the received assignment setting; and a correspondence display unit that, when a user selects one of the plurality of input connector icons on the setting management screen in the confirmation mode, changes the display mode of the illuminator icon associated with the selected input connector icon on the setting management screen based on the stored assignment setting.

[0016] The lighting power supply device program may be distributed electronically or may be recorded on a program recording medium such as a CD, DVD, or flash memory. [Effects of the Invention]

[0017] As described above, the lighting power supply device according to the present invention allows for easy setting of which illuminator a command signal input to an input connector is to be assigned to, and the correspondence display unit changes the display mode of the illuminator icon associated with the selected input icon on the setting management screen, allowing the user to easily grasp the correspondence between the linked input connectors and the illuminators. This allows for increased flexibility in assignment settings as a lighting power supply, while improving usability. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] A lighting power supply device 100 according to one embodiment of the present invention and a lighting system 200 using the same will be described with reference to the accompanying drawings.

[0020] The lighting system 200 of this embodiment is an inspection system used, for example, for visual inspection of workpieces W, and is configured to irradiate light onto one workpiece W from four directions in different ways, and capture an image of the workpiece W using reflected or scattered light from the workpiece W with a camera C installed directly above the workpiece W.

[0021] That is, the lighting system 200 of this embodiment includes four inspection illuminators L1, L2, L3, and L4, and a multi-channel inspection lighting power supply device 100 in which the four illuminators L1, L2, L3, and L4 are each connected to an individual channel and can be powered in an individual manner.

[0022] The illuminators L1, L2, L3, and L4 are equipped with, for example, LEDs, and their brightness, light-emitting duration, and light-emitting timing are controlled by the power supplied from the lighting power supply device 100. In this embodiment, the illuminators L1, L2, L3, and L4 are all of the same type, but the illuminators L1, L2, L3, and L4 may be of different types. Furthermore, the number of illuminators L1, L2, L3, and L4 is not limited to four, and two or more illuminators may be connected to the lighting power supply device 100.

[0023] The lighting power supply device 100 comprises a power supply main unit MB to which each illuminator L1, L2, L3, L4 is connected to each channel CH1, CH2, CH3, CH4 by a power supply cord, and a computer COM connected to the power supply main unit MB and used to perform various settings.

[0024] The power supply main body MB includes at least a power supply unit PS that has multiple channels CH1, CH2, CH3, and CH4 and that outputs power from each channel CH1, CH2, CH3, and CH4 individually according to the parameters of each control item set for each channel CH1, CH2, CH3, and CH4, and a signal control unit SC that controls the power output from each channel CH1, CH2, CH3, and CH4 of the power supply unit PS based on a command signal input from outside. In this embodiment, the command signal is a trigger signal that controls the emission start timing of any of the illuminators L1, L2, L3, and L4.

[0025] The signal control unit SC includes a plurality of input connectors N1, N2, N3, and N4 to which trigger signals are input, a signal output unit SC1 that outputs the trigger signals input to the input connectors N1, N2, N3, and N4 to the power supply unit PS as signals for controlling illuminators L1, L2, L3, and L4 connected to any of channels CH1, CH2, CH3, and CH4 of the power supply unit PS, and a plurality of output connectors N6, N7, N8, and N9 that output the trigger signals input to the input connectors N1, N2, N3, and N4 to the outside so as to supply them in parallel to devices other than the power supply unit PS.

[0026] Here, each input connector N1, N2, N3, and N4 and each output connector N6, N7, N8, and N9 is assigned a connector number for identification. In this embodiment, connector numbers 1 to 4 indicate the input connectors N1, N2, N3, and N4, and connector numbers 6 to 9 indicate the output connectors N6, N7, N8, and N9. Also, by default, trigger signals input to input connectors N1, N2, N3, and N4 with connector numbers 1 to 4 are output from the signal controller SC to the power supply unit PS as trigger signals for controlling illuminators L1, L2, L3, and L4 connected to channels CH1, CH2, CH3, and CH4 with the same channel numbers. Furthermore, by default, trigger signals input to input connectors N1, N2, N3, and N4 with connector numbers 1 to 4 are output as trigger signals to the outside from output connectors N6, N7, N8, and N9 with connector numbers equal to the connector numbers of the input connectors N1, N2, N3, and N4 plus 5.

[0027] Incidentally, trigger signals input to input connectors N1, N2, N3, and N4 of the signal control unit SC can be changed so that they are output from the signal output unit SC to channels CH1, CH2, CH3, and CH4 with channel numbers different from the connector numbers, or so that trigger signals are output from output channels N6, N7, N8, and N9 different from the default. In other words, the signal control unit SC is configured so that the user can freely change the correspondence between the trigger signals and the illuminators connected to the input connectors N1, N2, N3, and N4, the output connectors N6, N7, N8, and N9, and the channels CH1, CH2, CH3, and CH4. User operations for changing these correspondences will be described later.

[0028] The power supply unit PS includes, for example, an AC / DC converter that converts commercial voltage into DC voltage for supplying to the LED illuminators L1, L2, L3, and L4. The power supply unit PS supplies power from each channel CH1, CH2, CH3, and CH4 in a preset manner based on a trigger signal input from the signal control unit SC to each channel CH1, CH2, CH3, and CH4, and controls the light emission modes of the illuminators L1, L2, L3, and L4. For example, when a trigger signal is input from the signal control unit SC to a certain channel, a predetermined number of pulses of voltage are supplied to the illuminators for a predetermined period of time after the trigger signal is input.

[0029] The computer COM is equipped with various input / output means IF such as a mouse and keyboard, memory, a CPU, a display DP, an A / D converter, a D / A converter, etc., and is configured to perform at least the functions of a trigger signal generator P1, a setting management screen display unit P2, an allocation setting reception unit P3, an allocation memory unit P4, and a correspondence relationship display unit P5 by executing a lighting power supply program stored in the memory and by various devices working together.

[0030] The trigger signal generator P1 outputs a trigger signal that pulses at a predetermined timing, for example, according to user settings. For example, if it is desired to periodically emit light from one of the illuminators, a trigger signal that pulses at predetermined intervals is output. In this example, the trigger signal generator P1 is implemented using the functions of the computer COM. However, the trigger signal generator P1's functions may also be implemented using, for example, a function generator. In this embodiment, the trigger signal output from the trigger signal generator P1 is configured to be input to an input connector with connector number 1. By default, the trigger signal output from the trigger signal generator P1 is used to control the illuminator L1 connected to channel N1 with channel number 1, and is also output in parallel to the input connector N6 with connector number 6 as a trigger signal for synchronizing the shutter control of camera C, for example. In the following description, to more clearly explain the features of this embodiment, it is assumed that the user has configured the trigger signal input to the input connector N1 with connector number 1 to control the illuminator L3 connected to channel CH3 with channel number 3, and that the same trigger signal as that input to the input connector N1 is output to the output connector N7 with connector number 7.

[0031] 3 to 8, the setting management screen display unit P2 displays a setting management screen PG on the display DP, which is used by the user to freely set the relationships between the input connectors N1, N2, N3, and N4, the illuminators L1, L2, L3, and L4, and the output connectors N6, N7, N8, and N9 related to trigger signals, and to check the set correspondence relationships. This setting management screen PG is configured to be switchable between at least two modes: a setting mode and a check mode.

[0032] In the setting mode, the user can assign which of the channels CH1, CH2, CH3, CH4 the trigger signal input to a certain input connector N1, N2, N3, N4 will be used to control the illuminators L1, L2, L3, L4 connected to, or which of the output connectors N6, N7, N8, N9 the trigger signal will be output to in parallel to the outside.

[0033] In the confirmation mode, the user can check the currently set assignment settings for trigger signals between the input connectors N1, N2, N3, N4, the illuminators L1, L2, L3, L4 connected to channels CH1, CH2, CH3, CH4, and the output connectors N6, N7, N8, N9.

[0034] 3 includes at least a plurality of input connector icons IN corresponding to the plurality of input connectors N1, N2, N3, and N4, an illuminator icon LT corresponding to the plurality of illuminators L1, L2, L3, and L4, an output connector icon OUT corresponding to the plurality of output connectors N6, N7, N8, and N9, a mode switching area MD provided with radio buttons for the user to switch between the setting mode and the confirmation mode, and a notification area NT notifying the user that the setting mode has been set. The user can assign trigger signals or check the assignment settings by clicking on various parts of the setting management screen PG with, for example, a mouse, which is an input / output means IF.

[0035] The assignment setting reception unit P3 receives a predetermined input from the user on the setting management screen PG in the setting mode as an assignment setting. Here, the assignment setting is used to assign to which channel or which output connector the signal control unit SC will output a trigger signal input to an input connector. Specifically, to perform the assignment setting, the user selects one of the input connector icons IN and at least one of the illuminator icon LT or output connector icon OUT as shown in FIG. 4 while the setting mode is selected as shown in FIG. 3. The assignment setting reception unit P3 receives a combination of the icons selected by the user as an assignment setting. For example, if the user wants to use a trigger signal input to input connector N1 to control illuminator L3 connected to channel CH3 and output the signal in parallel from output connector N7, the user selects the input connector icon IN, which has the corresponding connector number 1 assigned to it, the illuminator icon LT, which has the illuminator number L3 assigned to it, and the output connector icon OUT, which has the connector number 7 assigned to it, with the mouse, as shown in FIG. 4. Note that the order in which the icons are selected during the assignment setting operation is not particularly limited.

[0036] As shown in FIG. 5, the setting management screen display unit P2 changes the display mode of a selected icon immediately upon selection, indicating to the user which icon is currently selected. Furthermore, only one input connector icon IN can be selected; if another input connector icon IN is selected, only the last selected icon remains selected. On the other hand, multiple illuminator icons LT and output connector icons OUT can be selected simultaneously. That is, a trigger signal input to one input connector N1 can be used to simultaneously control multiple illuminators L1, L2, L3, and L4, or the same trigger signal can be simultaneously output externally from multiple output connectors N6, N7, N8, and N9. As shown in FIG. 5, clicking the notification area NT after selecting each icon confirms the assignment settings based on the combination of selected icons.

[0037] The assignment settings accepted and confirmed by the assignment setting acceptance unit P3 are stored in the assignment memory unit P4. In correspondence with the assignment settings stored in the assignment memory unit P4, the signal control unit SC outputs trigger signals input to the input connectors N1, N2, N3, N4 to the channels CH1, CH2, CH3, CH4 to which the illuminators L1, L2, L3, L4 are connected or to the output connectors N6, N7, N8, N9.

[0038] 6 to 8, when the setting management screen PG is in the confirmation mode and a user selects one of the multiple input connector icons IN, the correspondence display unit P5 changes, based on the assignment settings stored in the assignment memory unit P4, the display mode of the illuminator icon LT corresponding to the illuminator L3 controlled by a trigger signal input to the input connector N1 corresponding to the selected input connector icon IN, or the display mode of the output connector icon OUT corresponding to the output connector N7 from which the trigger signal is output to the outside, on the setting management screen PG. That is, the correspondence display unit P5 treats the stored assignment settings as data in which one or more illuminator icons LT or output connector icons OUT are associated with one input connector icon. The correspondence display unit P5 is configured to change the display mode of the illuminator icon LT or output connector icon OUT associated with the input connector icon IN selected on the confirmation screen PG by the user.

[0039] In this way, with the lighting power supply device 100 of this embodiment, it is possible to easily and freely set which of the illuminators L1, L2, L3, and L4 the trigger signals input to each input connector N1, N2, N3, and N4 will be used to control, and which of the output connectors N6, N7, N8, and N9 will output the trigger signals externally in parallel.

[0040] Furthermore, on the confirmation mode setting management screen PG, the user can simply click on one of the input connector icons IN, and the display mode of the icon corresponding to the illuminator L1, L2, L3, L4 or output connector N6, N7, N8, N9 to which the trigger signal is assigned will change, making it easy to understand the correspondence between them.

[0041] Therefore, even if the user has made complex assignment settings or repeatedly changed various assignment settings, it is possible to check how the trigger signals will be used without actually turning on the illuminators L1, L2, L3, and L4, making it easier for the user to make lighting settings suitable for inspection.

[0042] Other embodiments will be described.

[0043] In the lighting power supply device of the above embodiment, the trigger signal, which is a command signal input to an input connector, can be assigned to both an illuminator and an output connector, but it may also be possible to set only which of a plurality of illuminators a command signal input to one of a plurality of input connectors is to be assigned to be used for controlling. In such a case, the output connector icon itself may be omitted from the setting management screen.

[0044] Command signals input from different input connectors may be superimposed and assigned to the same illuminator or output connector. For example, if the command signal is a trigger signal and it is desired to consolidate illuminators that would emit light at different timings in a conventional setting into a single illuminator, the conventional trigger signal can be used as is if such a setting is permitted. Conversely, if controlling illuminators by simply superimposing command signals causes malfunctions or the like, the assignment setting receiving unit may be configured so that an illuminator icon or output icon to which an assignment setting for a trigger signal input from one input connector has already been made cannot be selected while an assignment setting for a trigger signal input from another input connector is being made.

[0045] Although a trigger signal is given as an example of a command signal, it is not limited to this and may be a command signal that includes not only a switch between on and off, but also a target dimming value, current value, etc.

[0046] Although the use of the command signal output from the output connector has been given as an example of a synchronization signal for synchronizing the opening and closing of the camera shutter with the timing of light emission, the use is not limited to this. The command signal may be output to an external device other than a camera that needs to be linked to the operation of the illuminator, or may simply be output to an external device as a monitoring signal for checking operation.

[0047] The change in the display mode of each icon on the setting management screen by the correspondence relationship display unit is not limited to that shown in the figure, and may be various. That is, it is sufficient if each set of icons to which an assignment setting has been made is displayed differently from other icons. Furthermore, the correspondence relationship display unit is not limited to changing the display mode of each icon based on the assignment setting when an input icon is selected. For example, the correspondence relationship display unit may be configured to change the display mode of an input connector icon to which an assignment setting has been made when an illuminator icon or an output connector icon is selected.

[0048] The number of channels, input connectors, and output connectors of the lighting power supply are not limited to four each, but may be any number greater than one, and some or all of the numbers may be different.

[0049] In addition, various modifications of the embodiments and combinations of parts of the embodiments may be made as long as they do not go against the spirit of the present invention. [Explanation of symbols]
