Reference numeral 801 denotes a mat, and 802 denotes a back plate, which sandwiches an exhibit (photograph) 800 therebetween. Mat 801
Is a deep blue sheet formed by opening an area corresponding to the inner area of the frame pattern 104 to expose the sandwiched exhibit 800, and having an outer peripheral edge formed in the same size as the inside of the outer frame pattern 103. . The back plate 802 is a backing plate formed in the same size as the outer peripheral edge of the mat 801, and the four corners of the mat 801 are decorated with decorative fasteners 804 to 807.
Is attached to the rear surface 102 of the transparent plate 100 so as to sandwich it.
The upper two decorative fasteners 804 and 805

In the display panel apparatus thus constructed, the display object 800 is attached to the back surface 102 of the transparent plate 100 with the display object 800 interposed between the mat 801 and the back plate 802, and is erected on a desk with the frame 700 as a leg. Or hanging metal fittings 808, 809
The power supply to the control device 600 is started by connecting the AC adapter 900 to an outlet of a commercial AC power supply and connecting the output terminal 902 to the input terminal 902.

When the control device 600 is supplied with power,
The CPU 610 executes the blink control of the LED group 500 according to the light emission control program stored in the memory 620. When the transparent plate 100 at this time is viewed from the front 101 side, the display object 800 and the mat 801 are illuminated by room light and appear to have the original color, but the rear surface 102 of the transparent plate 100 surrounds the display object 800. Double-printed frame-shaped patterns 103 and 104 printed on the transparent plate 10
The small holes 200 and the fluorescent optical fibers 300 scattered so as to penetrate 0 are illuminated by the light emission of the LED group 500 and change in color. In this embodiment, control device 600 first turns on only red LED 501 to generate red illumination light, and then turns on blue LED 502 while gradually turning off red LED 501 over time, thereby turning on red light. And blue light are mixed to generate purple illumination light, and then only the blue LED 502 is turned on to generate blue illumination light. Thereafter, the red LED 501 is turned on while the blue LED 502 is gradually turned off with time, and the red LED is turned on. After the generation of the violet illumination light in which the light and the blue light are mixed, the light emission control that returns to the red illumination light by turning on only the red LED 501 is repeatedly executed.

The light emitted from the LED group 500 is transmitted to the transparent plate 1
The light enters the transparent plate 100 from the inner surfaces of the light receiving chambers 111 to 115 formed at 00, and the patterns 103 and 104 and the small holes 200 are formed.
These are colored by illuminating them against the fluorescent optical fiber 300.

First, the red LED 50 of each LED group 500
When 1 is turned on, the appearance (view) of the transparent plate 100 viewed from the front 101 side is the pattern 103, 10 printed in milky white.
4 is colored in a reddish pink color, which is a mixture of red and white, and all the small holes 200 and the fluorescent optical fibers 300 are colored in a reddish color.

Next, when the blue LED 502 is gently turned on while the red LED 501 is gently turned off, the light emission of the two LEDs 501 and 502 is mixed in the process of turning off the red LED 501 and turning on the blue LED 502, so that the pattern 103 , 104 gradually change from pink to purple, the small holes 200 gradually change from red to blue, and the fluorescent optical fiber 300 gradually changes from red to the unique fluorescent color of each fluorescent optical fiber 300. Change.

When the red LED 501 is completely turned off and the blue LED 502 is completely turned on, the transparent plate 10
The appearance of the front surface 101 side of 0 changes completely from the initial state.
The patterns 103 and 104 change from red to sky blue in which blue and white are mixed, and the single-color fluorescent optical fibers 300 of red, yellow, green, blue, etc.
It changes to the original fluorescent color of 0. Also, the small holes 200 to which the fluorescent optical fibers 300 are not fitted change from red to blue. This is because, due to the difference in the emission wavelength of the LED group 500 (light source), all of the illumination by the red LED 501 is colored red, and the illumination by the blue LED 502 is colored to the color unique to each member.

Next, when the red LED 501 is slowly turned on while the blue LED 502 is slowly turned off, the pattern 1
Numerals 03 and 104 gradually change from milky white to red, all fluorescent optical fibers 300 gradually change from a unique color to red, and small holes 200 where the fluorescent optical fibers 300 are not fitted change from blue to red. Changes slowly.

Accordingly, the photograph or the picture, which is the exhibit 800, changes color gradually with time by changing the emission color of the LED group 500 with time, as described above.
The brightness of the heavy frame-shaped patterns 103 and 104 and this pattern 1
In the area between 03 and 104, the small hole 200 which is scattered with the deep blue color which is the ground color of the mat 701 as a background and gradually discolors with time as described above, and the sensation surrounded by the brightness of the fluorescent optical fiber 300. It will be displayed in the center of the exhibition space. In addition, depending on the contents of the exhibit 800, the viewer can be provided with comfort.

In this embodiment, the red LED 501 and the blue LED 502 are used as illumination light sources.
It is also possible to use LEDs that emit light of other colors instead or in combination. Further, the blinking time of each LED can be arbitrarily changed.

The frame-shaped patterns 103 and 104 can be formed by printing in an arbitrary shape and color, or by attaching a colored tape.

Further, a small hole 200 formed in the transparent plate 100 is formed.
Need not penetrate the transparent plate 100,
0 may be formed from the back surface 102 side so that the front surface 101 side is slightly left. Further, the fluorescent optical fiber 300 fitted in the small hole 200 can be changed to a phosphor having another similar property.

Further, the illumination light for the transparent plate 100 may be changed so as to enter from the upper end or the lateral end of the transparent plate 100.

[0028]

According to the present invention, it is possible to easily illuminate an exhibit such as a photograph or a painting without depending on the installation position of the display panel device, and to change the installation position of the display panel device. Illumination that does not require the accompanying position change or adjustment can be realized. In addition, since the color of the illumination changes over time, impressive illumination can be performed on the exhibit.
