TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lighting device that illuminates a subject having a property of being sensitive to ultraviolet light.
[0002]
[Prior art]
In recent years, paints, pigments, paints, dyes, etc. that develop color or reflect ultraviolet light in response to ultraviolet light when they are irradiated with ultraviolet light have been developed, and paintings, prints, posters, Various murals, advertisements, booklets, etc. have been created. Such a product, under irradiation of white light by an incandescent lamp or the like, develops the color originally possessed by the pigment or the like, whereas when irradiated with ultraviolet rays, the coloration of a color different from the color possessed by the pigment or the like is converted to the ultraviolet ray. Wake up in response. For this reason, it is possible to present a situation where there is no coloring based on ultraviolet rays and a situation where there is coloring based on ultraviolet rays, which gives surprise and ease to viewers and viewers of paintings and advertisements. .
[0003]
In an illumination device that illuminates a painting or the like as a subject, the state of irradiation of the subject with ultraviolet rays may be changed. For this reason, for example,Hei 11-339975There has been proposed an illumination device in which an ultraviolet lamp that emits ultraviolet light and a white light are used in combination, and the ultraviolet light that contributes to the color development of the subject is adjusted by offsetting the white light with white light, thereby changing the coloration state.
[0004]
[Problems to be solved by the invention]
The conventional lighting device can temporally change from a pattern of a daytime atmosphere to a pattern of a nighttime atmosphere by changing the color development state. However, since the state of the pattern transition required by a viewer or a viewer is various, there is room for diversification and improvement of illumination of a subject having a property of being sensitive to ultraviolet rays.
[0005]
The present invention has been made in order to solve the above problems, and has an object to diversify the illumination when illuminating a subject having the property of being sensitive to ultraviolet light, and to provide various improvements such as giving a stronger impression. I do.
[0006]
[Means for Solving the Problems and Their Functions and Effects]
To solve at least some of these issues,Light of the lightThe lighting device
An illumination device for illuminating a subject having a property of being sensitive to ultraviolet light,
An ultraviolet lamp installed so that the object can be irradiated with ultraviolet light,
A visible light lamp installed to be able to irradiate the subject with white light or visible light in a predetermined wavelength range,
First control means for periodically turning on and off the ultraviolet lamp so that the amount of ultraviolet light periodically increases and decreases;
The amount of visible light is the lighting cycle of the ultraviolet lamp.While increasing and decreasing at the same cycle as above, the amount of visible light isSecond control means for controlling lighting of the visible light lamp so as to periodically increase and decrease with a phase difference;
Cycle changing means for changing and setting the lighting control cycle of the first and second control means;
Phase difference changing means for changing and setting the phase difference.
It is characterized by the following.
[0007]
The present invention having the above configurationLight of the lightIn the bright device, the irradiation of the object with ultraviolet light and the irradiation of white light or visible light in a predetermined wavelength range (hereinafter, this irradiation is referred to as visible light irradiation) is explained. It is assumed that the amount of visible light periodically increases and decreases with a phase difference from the ultraviolet irradiation cycle. As a result, the state of the object being sensitive to ultraviolet light is such that the ultraviolet light irradiation is offset by visible light irradiation out of phase with the ultraviolet light irradiation. Then, in the first lighting device, since the ultraviolet irradiation cycle and the visible light irradiation cycle are changed, the state (situation) of the ultraviolet light sensitivity of the subject changes according to the changed cycle. As a result, it is possible to cause the subject to respond to ultraviolet rays, specifically, the transition of the pattern in a painting or the like in a short time, or to cause the transition of the pattern slowly, and it is possible to variously adjust such a transition state. Therefore,Light of the lightAccording to the illumination device, it is possible to diversify illumination when illuminating a subject having a property of being sensitive to ultraviolet light.
[0008]
The term "white light" as used herein refers to light whose spectral distribution spreads over substantially the entire visible range and looks white to the naked eye, and includes light emitted by incandescent lamps, white fluorescent lamps, halogen lamps, and the like. In addition, the waveforms of the increase and decrease of the light amount of the ultraviolet lamp and the increase and decrease of the light amount of the white light include waveforms such as a sine wave, and also a waveform that monotonically increases and then becomes constant at the maximum value and then monotonically increases and becomes constant at the minimum value. Including.
[0009]
The visible light in the predetermined wavelength range may be light having a color (wavelength) capable of canceling out ultraviolet light emitted by an ultraviolet lamp, and may be light yellow, light orange, or the like. That is, in the case of using such visible light, an appropriate selection may be made according to the situation of the subject's sensitivity to ultraviolet light, the subject motif when the subject does not cause ultraviolet sensitivity, and the like.
[0010]
the aboveOf the present inventionSince the illumination device changes and sets the phase difference between the ultraviolet irradiation cycle and the visible light irradiation cycle, the sensitivity difference can be changed each time the phase difference is changed. If the phase difference is changed regularly or irregularly and the degree of change is adjusted variously, the sensitivity difference can be expressed in various modes, and the illumination of the subject can be further diversified.
[0012]
The present invention having the above configurationClearThe lighting device can adopt the following modes.
That is, the cycle changing means includes:
Having a selection unit for selecting the lighting control cycle from a plurality of preset lighting control cyclesTossCan be
This makes it possible to easily change various states of the ultraviolet light sensitivity of the subject based on the change in the ultraviolet irradiation cycle and the visible light irradiation cycle. For example, if three lighting control cycles of a long cycle, a middle cycle, and a short cycle are prepared in advance, and one cycle is selected from the three lighting control cycles by using a switch, a dial, or the like, these switches can be used. Thus, the lighting control cycle can be easily selected by such operations as described above, and the ultraviolet light sensitivity state of the subject can be easily changed based on the selected cycle. In other words, you can easily change the transition of a pattern in a painting or the like from a short time to a long time, or from a long time to a short time or a middle time. it can.
[0013]
Further, the cycle changing means includes:
The lighting control cycle may include a variable setting unit that variably sets the lighting control cycle such that the lighting control cycle is different for each predetermined period.
This makes it possible to automatically change the transition of the ultraviolet light responsive state of the subject at predetermined time intervals, so that it is possible to further diversify the illumination. For example, the transition of a pattern in a painting or the like can be automatically changed at predetermined time intervals, such as a transition from a long time to a short time, a transition to a medium time, and a short time again.
In this case, if the lighting control cycle is variably set to a fluctuation cycle, it is possible to give a comforter based on the fluctuation control to a viewer or an observer of the subject causing the transition of the ultraviolet light-sensitive state. Moreover, it is possible to make it difficult for these viewers to feel tired and monotonous. In the case of a pattern in a painting or the like, a feeling (for example, a feeling of appreciation) held by the viewer or the like changes in a fluctuation cycle based on the pattern transition. Therefore, the fluctuation in the appreciation may be referred to as a sense of security, a sense of satisfaction, and a feeling of ease. You can give comfort.
[0014]
In addition, the first control unit controls the lighting of the ultraviolet lamp to adjust at least one of the maximum value and the minimum value of the amount of ultraviolet light to be irradiated,
The second control means having at least one of both light quantity adjustment means of visible light quantity adjustment means for controlling at least one of the maximum value and the minimum value of the quantity of visible light emitted by controlling the lighting of the visible light lamp; can do.
This makes it possible to make the sensitivity sensitivity difference of the subject to the ultraviolet light more prominent and to make the sensitivity difference small, so that the illumination of the subject can be diversified. That is, in addition to the above-described adjustment of the phase difference, the illumination of the subject can be diversified by the light amount control.
[0015]
Further, the first control means controls lighting of the ultraviolet lamp so that the amount of ultraviolet light does not become zero,
The second control means may control lighting of the visible light lamp so that the amount of visible light does not become zero.
In this case, the control of the ultraviolet lamp or the visible light lamp does not require switching via zero light amount, so that the life of these lamps can be extended. Particularly, in the case of an ultraviolet lamp, since a discharge lamp is frequently used, it is useful for improving the durability life.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of a lighting device according to the present invention will be described based on examples. FIG. 1 is an explanatory view for explaining an illuminated picture frame 10 when the illuminating device of the present invention is applied to picture frame illumination, FIG. 2 is an explanatory view for explaining the picture frame 10 viewed from a lateral direction, and FIG. It is a block diagram for explaining a control system configuration.
[0025]
As shown in the drawing, the frame 10 has an illumination device 20 at the upper end of a frame portion 12 for storing a design subject P such as a painting or a poster.
[0026]
The picture frame portion 12 is provided with glass on its front face, and accommodates a design subject P in an internal recess. The design subject P can be replaced from the back face of the picture frame.
[0027]
As shown in FIG. 1A, the design subject P depicts a scene in which a wavy lake surface Ls and a lush sky Sb in the background thereof are viewed from the lake shore, and a tree Ja that has grown to the lake shore is on the left of the lake surface. On the right side of the lake surface, a waterfall Fa flowing down to the shore of the lake, a tree Jb behind the waterfall Fa, and a tree Jc in the foreground are drawn. To create these patterns, paints that are colored in response to the ultraviolet rays when they are irradiated with the ultraviolet rays are used. Under the irradiation of sunlight or white light such as a white fluorescent lamp or an incandescent lamp, the paint develops the color inherent to the paint (for example, red, blue, yellow, pink, green, etc.) and emits ultraviolet light. Upon irradiation, a color different from the color of the paint (for example, navy blue, indigo, purple, red, orange, etc.) is generated in response to ultraviolet rays. In addition, when the amount of received ultraviolet light increases, the intensity of the sensitive color can be changed. Utilizing this property, the design subject P is drawn with the above-described motif in the creation of the design, with the aim of expressing the design in a state of being irradiated with ultraviolet rays. That is, as shown in FIG. 1B, the entire design of the symbol subject P is buried in deep darkness under the irradiation of ultraviolet rays. Specifically, almost all of the lake surface Ls and almost the sky Sb are formed. Trees Ja, trees Jb, and trees Jc around the lake surface become dark blue, and many stars St, aurora Oa and moon Ms appear in the sky Sb in various colors, and the lake surface Ls is lit by moonlight. The undulating lake surface portion Lr appears to reflect the moonlight, and the waterfall Fa also appears to be lit by the moonlight. That is, the design subject P is created so that the daytime scene of FIG. 1A and the nighttime scene of FIG.
[0028]
Here, the base used for the above-mentioned symbol subject P will be described. In the present embodiment, it is assumed that the substrate itself develops color in response to ultraviolet irradiation on a substrate such as a paper or a cloth when the design subject P is a printed matter such as a painting or screen printing, or a wall substrate when the mural is a mural. . For example, the drawing cloth is assumed to emit fluorescent light in white or light color in response to ultraviolet rays, and a pattern is drawn on the drawing cloth with the special paint described above, assuming a daytime scene and a nighttime scene as described above.
[0029]
Since the base is configured in this manner, when ultraviolet irradiation is performed as described below, not only the appreciation effect due to the color development of the paint, but also the exposed part of the base or the thin part of the paint applied to the base is thin. It also produces the UV color effect of the substrate. For this reason, compared to the case of using a substrate that does not cause ultraviolet coloring, the effect of producing and appreciating night scenes as a whole symbol can be enhanced, and the pattern transition effect between daytime scene and night scene can also be improved. Can stand out.
[0030]
The lighting device 20 includes a device main body 22 on the upper back surface of the frame 10, and the lighting unit 24 is held by two arms 23 from the device main body 22. The lighting unit 24 is rotatable at the base of the arm 23 on the apparatus main body side, and is rotatable between a lighting position illustrated and a position above the frame. The lighting unit 24 is turned to the lighting position, thereby turning on a lighting main switch (not shown).
[0031]
The illumination unit 24 includes a straight tube cylindrical ultraviolet fluorescent lamp (hereinafter abbreviated as BL) 25 substantially horizontally inside a cap 24a having an open lower end, and is arranged in the BL and an incandescent lamp (hereinafter abbreviated as WL). 26) are provided in a dotted manner. As shown in FIG. 3, BL25 and WL26 are connected to inverters 27 and 28, respectively, and are turned on by the inverters. In this case, the BL 25 and the WL 26 illuminate the symbol subject P over the entire area in a state where the illumination unit 24 is located at the illumination position. Each of the inverters is configured to supply a current to the BL25 or WL26 in a waveform such that the light amount increases or decreases in accordance with a control signal from an electronic control device 31 described later, and to perform lighting control while increasing or decreasing the light amount of the BL25 or WL26. . The BL 25 is configured to emit ultraviolet light in a wavelength range (about 340 to 400 nm) harmless to the human body. All of the WLs 26 are turned on at the same timing.
[0032]
Next, a control system of the illumination device 20 will be described. As shown in FIG. 3, the picture frame 10 has a control device 30. The control device 30 is built in the device main body 22 at the upper edge of the frame. In addition to the inverters 27 and 28, an electronic control device 31, a remote control light receiving unit 32, a setting switch group 33 having various switches, It has a human body detection sensor 34 and an automatic ON / OFF switch 35. The remote control light receiving unit 32 is provided on the front surface of the device main body 22, receives the transmission light of the remote controller (remote controller) RM, and inputs a control signal according to the light receiving state to the electronic control device 31. The setting switch group 33 outputs a control signal corresponding to the operation state of the switch to the electronic control device 31, and is used when setting the lighting condition of the lighting device 20 instead of the remote controller RM. That is, in this embodiment, various lighting conditions can be set by either the remote controller RM or the setting switch group 33. The human body detection sensor 34 is configured by a light reflection type optical sensor, and is provided on the front surface of the apparatus main body 22. When the viewer approaches the front of the frame 10, the human body detection sensor 34 outputs a control signal to that effect to the electronic control device 31. The auto ON / OFF switch 35 is used to variously change the lighting state presented by the lighting device 20 or to perform lighting only when a human body approaches. When the switch is ON, the lighting state is changed. A control signal to the effect is output to the electronic control unit 31. If the switch is OFF, a control signal for performing illumination in a situation where the human body approaches the main frame is output to the electronic control device 31. The setting switch group 33 and the automatic ON / OFF switch 35 are provided at appropriate locations on the apparatus main body 22.
[0033]
The electronic control unit 31 receives signals from the above-described sensors and switches, and performs overall control of lighting of the entire lighting device 20. The electronic control unit 31 includes a CPU that performs a logical operation, a ROM that stores a program described later in advance, a RAM that temporarily stores data, a backup RAM that retains data even after power is turned off, a timer that displays elapsed time, It is configured as a logical operation circuit having a clock for specifying time or date, and these are mutually connected via a common bus. The above-mentioned sensors and the like are connected to an input / output port (not shown).
[0034]
Next, illumination control (routine) performed by the illumination device 20 of the present embodiment having the above-described configuration will be described. FIG. 4 is a flowchart showing the processing contents of the lighting routine, FIG. 5 is a flowchart showing the processing contents of the human body detection lighting included in the lighting routine, and FIG. 6 is an explanatory diagram for explaining the processing contents executed in the lighting routine. is there.
[0035]
As shown in FIG. 4, this lighting routine is repeatedly executed at predetermined time intervals after an initial process executed only when the power is turned on, that is, after clearing an internal register of the CPU. When the lighting routine is executed, first, the operation status of the auto ON / OFF switch 35 is scanned to determine whether the switch is ON or OFF (step S100). If the switch is OFF, the process proceeds to a human body detection illumination process (step S200) described later. If the switch is ON, the illumination mode is set to a predetermined value in the RAM in order to illuminate the design subject P after changing the illumination status. Read from the address (step S105). The illumination mode is specified by a pattern of increase / decrease of the amount of ultraviolet light involved in the sensitivity of the design subject P to ultraviolet light. In this embodiment, as shown in FIG. There are prepared a mode M in which the speed changes at a medium speed and a mode F in which the amount of light changes at a high speed. These illumination modes are set through operation of a predetermined button on the remote control RM. That is, the remote controller RM converts the mode change signal into an optical signal and outputs it each time the button is operated, and the electronic control unit 31 switches the lighting mode to the mode S, the mode M, or the mode every time the optical signal is input. The order is changed in the order of F, and the changed lighting mode is updated and written in a predetermined address of the RAM. By operating a predetermined switch of the setting switch group 33, the illumination mode is updated in this manner. At the time of the first execution of the main lighting routine after the power is turned on, the mode S is written in the RAM as the initial lighting mode by the initial processing, so that the mode S is initially read in step S105. In this case, if the changed lighting mode is stored in the backup RAM, the lighting mode when the power is turned off is read after the next power-on.
[0036]
Here, the illumination mode will be described in detail.
As shown in FIG. 6A, the lighting pattern of the BL 25 in the mode S is such that the light amount has a long cycle Ts in a predetermined range from zero light amount (extinguish) to the maximum irradiation amount (max) of the fluorescent lamp. Increase or decrease as shown by the solid line. The lighting pattern of the WL 26 has a long period Ts in a predetermined range (for example, a range of 20 to 90%) from the light amount of zero (extinguished) to the maximum irradiation amount (max) of the white lamp, and is indicated by a dotted line in the drawing. Increase or decrease as shown. At this time, the lighting pattern of BL25 and the lighting pattern of WL26 are set to have a phase difference ΔTs (a phase difference for a half cycle) at which the light amount increase / decrease waveform is inverted. Therefore, a phenomenon of reducing the amount of white light occurs in the process of increasing the amount of ultraviolet light. In this process, the amount of ultraviolet light involved in color development based on the sensitivity of the design subject P to ultraviolet light gradually increases as the offset by white light weakens. The amount of ultraviolet light involved in color formation is maintained at the largest upper limit when the amount of ultraviolet light is constant at the upper limit and the amount of white light is constant at the lower limit, and is gradually reduced in the subsequent process of reducing the amount of ultraviolet light and increasing the amount of white light. I do. In the process in which the amount of ultraviolet light is constant at the lower limit and the amount of white light is constant at the upper limit, the state in which the color-related ultraviolet rays are all offset by the white light is maintained. For this reason, in the process of increasing the amount of ultraviolet light, the design subject P increases and expresses the degree of color development based on the gradual increase in the amount of ultraviolet light involved in color development. In the process where the amount of ultraviolet light is constant at the upper limit, the degree of color development is maintained and developed to a maximum. In the process of reducing the amount of ultraviolet light, the degree of color formation is reduced and expressed based on the gradual decrease in the amount of ultraviolet light involved in color formation, and in the subsequent process where the amount of ultraviolet light is constant at the lower limit, no ultraviolet response occurs and no color formation based on this occurs. .
[0037]
In the mode M shown in FIG. 6B, the lighting pattern of the BL 25 and the lighting pattern of the WL 26 shifted by a half-cycle phase difference from the lighting pattern of the BL 25 change from zero light (light off) to white light as shown by the solid and dotted lines in the figure. In a predetermined range (for example, in the range of 20 to 90%) up to the maximum irradiation light amount (max) of (1), the light amount increases and decreases in the middle cycle Tm. Even in this mode M, the amount of the color-related UV light gradually increases, maintains the upper limit, gradually decreases, and maintains the lower limit in each process as in the case of the mode S described above. In a cycle (middle cycle Tm) shorter than (long cycle Ts), the increase in the degree of color development, the maximum maintenance, the decrease and the non-color development are repeated. Similarly, in mode F of FIG. 6C, both lighting patterns are repeated in a short cycle Tf with a phase difference of a half cycle, so that in this mode F, the cycle (short) is shorter than the cycle in mode M (middle cycle Tm). In the cycle Tf), the color development degree is repeatedly increased, maintained at the maximum, reduced, and non-colored.
[0038]
In each of the illumination modes described above, the lower limit of the light amount of the lighting pattern was set to about 20% of the maximum irradiation light amount (max) of each lamp. Therefore, it is not necessary to control the energization of the BL 25 and the WL 26 from the extinguishing state to the illuminating state, and it does not cause flickering. In particular, in the case of the BL 25 that is lit by using the discharge phenomenon, the lower limit of the light amount is set to about 20% of the maximum irradiation light amount (max) of the lamp, so that the discharge phenomenon does not inadvertently disappear. . Therefore, it is preferable because the BL 25 does not lose its light.
[0039]
In the present embodiment, not only the design subject P alternately expresses the daytime scene and the nighttime scene, but also the maintenance of the daytime scene and the maintenance of the nighttime scene are taken into consideration. To maintain maximum and non-coloring. However, if it is a design subject for which it is sufficient to express a scene and another scene alternately, as shown in FIG. 7, the lighting pattern of BL25 and the lighting pattern of WL26 are increased or decreased like a sine waveform. The waveform may be a long cycle, a middle cycle, or a short cycle.
[0040]
Returning to FIG. 4 and explaining the lighting routine, following step S105, both lighting patterns of the BL25 and WL26 in the read lighting mode are specified (step S110). For example, if the read illumination mode is mode S, the lighting pattern in FIG. Thereafter, it is determined whether or not the phase difference between the two lighting patterns has been changed and set based on the operation status of the remote controller RM or the setting switch group 33 (step S115). If a negative determination is made here, the process proceeds to step S125 described later, and if an affirmative determination is made, the phase difference is the one after the setting change (step S120). FIG. 8 is an explanatory diagram for explaining how the phase difference between the lighting patterns of BL25 and WL26 is changed.
[0041]
In the initial state, the phase difference is set to the half cycle described above, but can be variously changed by the remote controller RM or a predetermined switch of the setting switch group 33. Therefore, for example, the phase difference ΔTm (half cycle = cycle / 2) between the lighting patterns of BL25 and WL26 in the mode M is set to the phase difference ΔTm * (for example, cycle / 3) after the change setting as shown in FIG.
[0042]
Subsequent to step S120, or following the negative determination in step S115, it is determined whether the upper and lower limit values of both lighting patterns have been changed and set based on the operation status of the remote controller RM or the setting switch group 33 (step S120). S125). Here, if a negative determination is made, the process proceeds to step S135 described later, and if an affirmative determination is made, the upper and lower limit values of the corresponding lighting pattern are set after the setting change (step S130). FIG. 9 is an explanatory diagram for explaining how the upper and lower limits of the lighting patterns of BL25 and WL26 are changed, and FIG. 10 is another explanatory diagram for changing the upper and lower limits of the lighting patterns of BL25 and WL26. FIG.
[0043]
In the initial state, the upper and lower limit values of the lighting pattern are set to 20% and 90% of the maximum irradiation light amount (max) as described above, but can be variously changed by the remote controller RM or predetermined switches of the setting switch group 33. It is. Therefore, for example, the upper and lower limits of the lighting patterns of BL25 and WL26 in mode M are set to 30% and 70% of the maximum irradiation light amount (max), as shown in FIG. Note that FIG. 9 also shows a case where the upper and lower limit values of the lighting patterns of BL25 and WL26 are changed and set, but as shown in FIG. 10, only the upper and lower limit values of one of the lighting patterns of BL25 are changed. You may make it set. Further, only the lighting pattern of the WL 26 may be set to change the upper or lower limit value or one of them.
[0044]
Subsequent to step S130 or following the negative determination in step S125, the signals of the lighting patterns of both BL25 and WL26 are output to the inverters 27 and 28 according to the illumination mode read in step S105 (step S135) At this time, the set phase difference and the upper and lower limit values are reflected. As a result, the lighting of the BL 25 and the WL 26 is controlled with a phase difference, and the pattern subject P is increased in the degree of color development, maintained at a maximum, and reduced in the period of the reading illumination mode (long period Ts in the case of the mode S). And non-coloring are repeated, in this order, the transition from the night scene gradually to the day scene, the maintenance of the day scene, the transition from the day scene to the night scene, and the maintenance of the night scene are caused, and these pattern transitions are presented to the viewer. I do.
[0045]
Subsequent to step S135, it is determined whether any of the illumination mode, the phase difference, and the upper and lower limit values have been changed based on the operation status of the remote controller RM and the setting switch group 33 (step S140). Then, the signal output of both lighting patterns BL25 and WL26 determined in step S135 is continued. On the other hand, if any one of the illumination mode, the phase difference, and the upper / lower limit value is changed, the process proceeds to step S100 to execute the processing described above in order to output a signal of the lighting pattern after the change setting. I do. That is, when the auto ON / OFF switch 35 is ON, the BL 25 and the WL 26 continue in a lighting pattern having a phase difference according to the illumination mode set to one of the modes S, M, and F. At this time, the setting of changing the phase difference between the two lighting patterns and the setting of changing the upper and lower limits of the lighting patterns are performed, and then the lighting of both lamps is controlled.
[0046]
For this reason, by the processing of steps S100 to S140, the state (situation) of the UV sensitivity of the design subject P in accordance with the respective cycles (long cycle Ts, middle cycle Tm, short cycle Tf) determined by the modes S, M, and F is determined. Can be transitioned. As a result, the symbol presented by the symbol subject P can be changed from the daytime scene to the nighttime scene slowly, relatively quickly, or in a short time. Therefore, since the situation of the scene transition can be variously adjusted, the illumination of the symbol subject P having a property of being sensitive to ultraviolet rays can be diversified, and the effect of appreciating the symbol subject P can be enhanced.
[0047]
In setting the lighting pattern cycle that determines the situation of the scene transition in this manner, in this embodiment, any one of the modes S, M, and F is selectively set only by operating the remote control RM or the setting switch group 33. The lighting pattern cycle can be set based on each mode. Therefore, the ultraviolet light sensitivity of the design subject P based on the change of the lighting pattern cycle can be easily changed in various ways by a simple operation such as a switch operation, so that the viewing effect of the design subject P can be easily enhanced.
[0048]
In setting the lighting pattern cycle, the following can be performed. In other words, each time a predetermined switch provided on the remote controller RM or the like is operated, the cycle of the lighting pattern is made longer or shorter stepwise. In this way, the lighting pattern cycle of BL25 and WL26 can be set to an arbitrary one through the switch operation. Therefore, when presenting the design subject P to the viewer, the transition situation between the night scene and the daytime scene presented by the subject can be easily adjusted and changed according to the viewer's preference and the intention of the subject presenter. And enhance the display effect.
[0049]
Further, since the phase difference between the lighting patterns of the BL 25 and the WL 26 can be changed and set, the degree of the cancellation of the ultraviolet light from the BL 25 with the white light of the WL 26 can be changed. Therefore, it is possible to further diversify the manner of the ultraviolet ray response based on the offset, thereby achieving further diversification of the illumination of the symbol subject P, and make the transition between the daytime scene and the nighttime scene various. Explaining with the drawing, in the initial process (time t1 to t2) in which the irradiation light amount increases in the lighting pattern of BL25 indicated by the solid line in FIG. , BL25, and the pattern subject P gradually shifts from the daytime scene to the nighttime scene. However, after the time t2 when the white light quantity of the WL 26 starts to increase, the sensitivity of the ultraviolet light sensitivity becomes constant because the white light and the ultraviolet light similarly increase the light quantity. Maintain the scene.
[0050]
By the way, after the time t2, although the sensitivity to the ultraviolet ray is constant, the sensitivity of the ultraviolet ray by the white light is small because the phase difference is smaller than the case where the phase difference is a half cycle. That is, although the symbol subject P expresses a night scene, the degree of color development is suppressed as compared with the case where the phase difference is a half cycle.
[0051]
Then, between the times t3 and t4, the light quantity of the WL 26 increases while the light quantity of the BL 25 remains constant at the upper limit, so that the sensitivity decreases in accordance with the increase of the white light quantity, and the sensitivity becomes the lowest when the white light quantity reaches the upper limit. It becomes. Therefore, between the times t3 and t4, the symbol subject P changes from the night scene to the day scene only during this short time interval, and maintains the day scene after the white light amount reaches the upper limit. Also, during the period from time t4 to the start time t5 of the next cycle, although the amount of light of BL25 and WL26 is reduced, all the ultraviolet rays are still canceled by the white light. , The design subject P maintains the daytime scene. In other words, by changing the phase difference, the transition state of the scene can be changed even when the cycle of the lighting pattern is the same, and diversification of illumination can be achieved.
[0052]
Further, in the present embodiment, as shown in FIGS. 9 and 10, the upper and lower limits of the amount of light in the lighting pattern of BL25 or WL26 are variably set, so that the sensitivity of the ultraviolet rays can be made more apparent by the sensitivity difference. , The difference in sensitivity can be small. Therefore, also from this point, it is possible to diversify the illumination of the symbol subject P. When the setting is changed as shown in FIG. 10, in a night scene in which the white light pattern indicated by the dotted line in the figure is the lower limit and the ultraviolet light is the upper limit, the degree of coloring by the ultraviolet light is suppressed by the small ultraviolet light upper limit value. In other words, it is possible to present a scene with a rather modest color development state even though it is a night scene. Conversely, if the upper limit of white light is reduced, a night scene with a high degree of color development can be presented.
[0053]
Next, a description will be given of a state of illumination in a situation where the auto ON / OFF switch 35 is turned off in step S100 of FIG. In this case, when the viewer (human body) approaches the frame 10, the process proceeds to the human body detection lighting process (step S200) so that the viewer can more effectively present the design subject P. In step S200, as shown in detail in FIG. 5, first, the human body detection sensor 34 is scanned to detect whether or not a human body as a viewer approaches the front of the frame 10 (step S210). Here, if a negative determination is made, a control signal for steadily lighting the BL25 and WL26 at a predetermined light amount (for example, a signal for presenting a daytime scene, that is, a control signal of the lower limit light amount in BL25, and a control signal of the upper limit light amount in WL26). Control progress) is output (step S220), and the routine goes to step S100 in FIG. While the human body is not detected by the human body detection sensor 34, the signal output in step S220 is continued, so that the daytime scene is continuously presented.
[0054]
On the other hand, following the affirmative determination in step S210, it is determined whether the situation of the human body detection has continued for a predetermined time (for example, 5 seconds) (step S230), and if a negative determination is made, the process proceeds to step S220. Transition. In other words, even if the human body approaches the frame 10, if the human body is detected for less than 5 seconds, the person simply walks in a short run without stopping, and in such a case, the scene transition of the design subject P occurs. Is unnecessary, and the lighting condition (daytime scene) is continued as it is. By doing so, a situation in which the control state of the lighting is changed every time a human body approaches the frame 10 does not occur, so that the control load is reduced, which is preferable.
[0055]
When an affirmative determination is made in step S230, it is expected that the viewer stops in front of the frame 10 and pays attention to the symbol subject P. Therefore, in this case, a control signal (for example, a daytime scene is presented) for lighting BL25 and WL26 in accordance with a standard lighting pattern (for example, a lighting pattern of mode S) that causes an increase or decrease in the amount of light in order to further alert. (Step S240), and the process proceeds to step S100 in Fig. 4. If the human viewer has stopped in front of the frame 10 for a certain period of time, the previous step S220 is performed. , The design subject P can be presented to the viewer so that the daytime scene and the nighttime scene alternately change, so that the viewing effect and the staging effect of the design subject P can be enhanced. Therefore, there is an advantage that the interest of the viewer can be increased.
[0056]
Next, a modified example will be described. FIG. 11 is a flowchart showing the content of the enhanced lighting process in the first modification. This series of processing of the emphasized illumination processing replaces the human body detection illumination processing (step S200) shown in FIG.
[0057]
As shown in the drawing, in this enhanced lighting process, similarly to steps S210 to S220 in step S200, the determination of the human body detection by the human body detection sensor 34 (step S310), and the continuous lighting control of the lamp with a constant light amount according to the determination result ( (Step S320), the continuation status determination of the human body detection time is performed (Step S330). Then, in a situation where it is expected that the viewer stops in front of the frame 10 and pays attention to the symbol subject P through the affirmative determination in step S330, first, the lighting pattern according to the lighting mode of the mode F is set to BL25. And a control signal for controlling the lighting of the WL 26 (step S340), and the signal output is continued for a predetermined time S1 (for example, about 5 minutes) (step S345). After that, the lighting mode is changed from mode F to mode M, and a control signal for controlling the lighting of BL25 and WL26 in a lighting pattern according to the mode M is output (step S350), and the signal output is output for a predetermined time S2. (For example, 5 to 10 minutes) (step S355). Next, the lighting mode is changed from the mode M to the mode S, and a control signal for controlling the lighting of the BL 25 and the WL 26 in a lighting pattern corresponding to the mode S is output (step S360). Is continued while detecting the human body (step S365).
[0058]
In the modification in which the lighting of the lamp is controlled in this manner, when the viewer is expected to stop in front of the picture frame 10 and pay attention to the design subject P, the periodic lighting pattern of the lamp is initially used. Are controlled in a mode F in which BL25 and WL26 are repeated in a short cycle. For this reason, the viewer approaching the design subject P stops the transition of the ultraviolet sensitive state of the design subject P (that is, the transition between the daytime scene and the nighttime scene) at the time when the viewer stops with interest or interest in the subject. It is possible to sense or appreciate in a cycle (short time), and then switch the lighting mode between mode M and mode S, so that the transition can be slowly and slowly appreciated. For this reason, it is possible to more strongly impress the transition (scene transition) of the UV-sensitive state presented by the subject to the human body (viewer, viewer, or the like) approaching the design subject P, and further increase the interest of these viewers or the like. In addition, there is an advantage that it can be reliably increased.
[0059]
Next, another modified example will be described. FIG. 12 is an explanatory diagram for explaining the state of illumination in the second modification.
[0060]
As shown in the drawing, this modified example is characterized in that the lighting mode is switched and changed in the following manner every time a predetermined lighting period Th elapses: mode F → mode M → mode S → mode F. That is, when a predetermined switch of the remote controller RM or the setting switch group 33 is operated, the electronic control device 31 transmits a control signal for lighting the BL25 and the WL26 in the lighting pattern in the mode F in the first lighting period Th. In the subsequent lighting period Th, a control signal for lighting the BL25 and WL26 in the lighting pattern of the mode S is output in the mode M in the next lighting period Th, and such a signal output is executed for each lighting period Th. I do.
[0061]
This makes it possible to automatically change the transition of the ultraviolet light-sensitive state presented by the symbol subject P (that is, the transition between the night scene and the daytime scene) for each lighting period Th, so that it is possible to further diversify the lighting. This modification changes the transition of the daytime scene and the nighttime scene from a transition in a short time to a transition in a shorter time, and further, periodically changes to a transition in a shorter time, and Interest, staging effects and appreciation effects can be enhanced. It should be noted that the transition may be reversed, in which case, after a long transition, the transition is short, and thereafter, the transition is at an intermediate time interval.
[0062]
FIG. 13 is an explanatory diagram for explaining an illumination state in another modification.
[0063]
As shown in the drawing, this modification is characterized in that the illumination mode is irregularly changed to any one of the mode F, the mode M and the mode S every time the predetermined illumination period Th elapses. . That is, when a predetermined switch (for example, an irregular lighting switch) of the remote controller RM or the setting switch group 33 is operated, the electronic control device 31 causes the lighting pattern in the mode M to be BL25 and WL26 in the first lighting period Th. A control signal for lighting the BL25 and WL26 in the lighting pattern in the mode S in the subsequent lighting period Th and in the mode M in the next lighting period Th is output. The output is executed for each lighting period Th.
[0064]
Here, an example of a method of irregularly setting the illumination mode to one of modes S, M, and F will be described. The electronic control unit 31 has a random number generation program in the ROM. Then, at the time of lighting under the condition that the irregular lighting switch is operated, the random number generation program is loaded every lighting period Th to generate a random number. On the other hand, as shown in FIG. 14, the electronic control device 31 stores a mode table in which random numbers are associated with modes. Therefore, the generated random numbers are collated with the mode table to determine the illumination mode for each illumination period Th, and the illumination mode is set irregularly.
[0065]
While the lighting mode is set irregularly in this way, as shown in FIG. 13, the lighting mode is, for example, mode M → mode S → mode M → mode F → mode S → mode S → mode M It changes in a fixed lighting period Th like. Accordingly, with this mode transition, the transition of the ultraviolet light-sensitive state presented by the symbol subject P (that is, the transition between the night scene and the daytime scene) can be automatically and irregularly changed for each lighting period Th. Lighting can be diversified.
[0066]
When the illumination mode is changed and set for each illumination period Th in this manner, the illumination period Th is determined by a fluctuation frequency (1 / f) determined by a fluctuation frequency that presents comfort to the five senses of a human or reduces a monotonous feeling to a stimulus. Can also be set to In this way, the transition of the ultraviolet light-sensitive state presented by the symbol subject P (that is, the transition between the night scene and the daytime scene) is expressed by the fluctuation control, and the viewer or the viewer who sees this transition is notified based on the scene transition. Since the feeling (e.g., the sense of appreciation) held by the appreciator is changed and changed in the fluctuation cycle, the fluctuation of the appreciation can provide comfort such as security, satisfaction, and comfort. In addition, it is possible to make it difficult for these viewers to feel tired and monotonous.
[0082]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described examples and embodiments, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. is there.
[0083]
For example, in the above-described embodiment and its modifications, a plurality of WLs 26 are provided on the shade 24a of the lighting unit 24, and all the WLs 26 are turned on with the same lighting pattern and timing. You can also. That is, for a certain WL 26, the lighting control for increasing or decreasing the light amount is performed in the above-described lighting pattern, and for the other WL 26, the lighting control is performed with the constant light amount at the upper limit level. Then, the lighting control in the lighting pattern described above is switched to the lighting control with the constant light amount, and the WL26 that has been the lighting control with the constant light amount is switched to the lighting control in the lighting pattern. Such control switching is sequentially performed at predetermined time intervals. This has the following advantages.
[0084]
The WL 26 to be controlled in the lighting pattern for increasing / decreasing the light amount is sequentially switched from the left WL 26 in FIG. 3 to the next one. Then, only the WL 26 that is controlled to be turned on in the lighting pattern is periodically involved in the UV offset of the BL 25, and the other WL 26 almost completely cancels the ultraviolet ray during the interval because of the upper limit.
[0085]
Therefore, in the partial area of the design subject P that can be irradiated only by the WL 26 in which the lighting control is performed in the lighting pattern, the ultraviolet light in the lighting pattern of the BL 25 is offset by the white light in the lighting pattern of the WL 26 as described above. As a result, a scene based on ultraviolet coloring (for example, a night scene) and a scene not based on ultraviolet coloring (for example, a daytime scene) change remarkably. However, in the region where the remaining WL 26, which is controlled to be constant at the upper limit, can irradiate, the scene that is not based on the ultraviolet coloring is maintained due to almost complete cancellation of the ultraviolet. Then, since the WL 26 that is the target of the lighting control in the lighting pattern is sequentially switched, the region where the scene based on the ultraviolet coloring and the scene not based on the ultraviolet coloring change remarkably shifts in the design subject P. For this reason, if the symbol presented by the symbol subject P is made to correspond to the shift of the scene transition, it is possible to appeal to the viewer even to the situation where the scene transition is shifted, and it is possible to enhance the viewing effect and the staging effect.
[0086]
Such lighting control can be easily applied to a lighting device configured to draw a pattern over a large area such as a mural and irradiate each area of the pattern with a spot.
[0087]
Further, in the above-described embodiment and its modified examples, the frame for illuminating the design subject P such as a painting has been described as an example, but the present invention is not limited to this. In other words, the present invention can be applied to various lighting devices that irradiate a flat or three-dimensional subject immersed in water, as well as a subject using pigments or paints having UV-sensitive characteristics for surface decoration of a three-dimensional exhibit. it can. Further, the present invention can be applied to a lighting device such as a showcase for displaying a card or a postcard having a design drawn with the pigment or the paint.
[0088]
Further, the configuration may be such that the illumination state at each time is maintained during the execution of the illumination control shown in FIG. 4, FIG. 5, or FIG. That is, a pause button is provided on the remote controller RM, and when the button is operated, a predetermined interrupt signal is input to the electronic control unit 31. When receiving the interrupt signal, the electronic control unit 31 interrupts the lighting control that has been performed up to that point, and controls the lighting of the BL 25 continuously while maintaining the light amount of the BL 25 at the time of the interruption, and the control signal of the WL 26 at the time of the interruption. A control signal for continuously lighting the WL 26 while maintaining the light amount is output. Thus, after the pause button operation, the scene at that time can be continuously presented. When the pause button is operated again, lighting control according to the lighting patterns of both lamps is restarted based on the new interrupt signal.
