Description

  The present invention relates to an internally-illuminated display board, and more particularly to a novel technique improved so as to be suitable for changing a color tone or blinking by remote control.

FIG. 5 is a schematic diagram illustrating an example in which a display board is provided.
Reference numeral 1 denotes a corridor, 2 denotes a wall, and a plurality of office doors 3 are arranged.
The department display board 4 is hung near each door.
This example is a general company's office, and the department display board 4 is written with a drawing room and design. In the present invention, for convenience of explanation, a hand-washing display and an emergency exit display are also referred to as a department display board.
Although FIG. 5 shows an example of a general company indoor, there are many similar examples in other indoors.
For example, in a hospital, the department display board is written with a surgical room, a medical examination room, an X-ray room, and the like. If it is a school, it is written as a science laboratory, a library, or a professor's room.

The department display board requires various functions.
First, a light-emitting display board is desirable for easy viewing, but it is more preferable if color-coded display is possible.
As a light-emitting display, a structure in which a fluorescent lamp is arranged on the back side of ground glass has been known for a long time. Furthermore, recently, a number of devices using light emitting diodes (LEDs) are being put into practical use.

It is designed to emit different color tones,
Further, the control LSI (7b) is characterized in that it emits a "red color tone meaning emergency" when it receives an alarm signal or an evacuation command.

According to the invention device of claim 3 described above,
In normal times, each of the large number of discolored internally illuminated display boards emits their own normal colors (colors other than “red” meaning emergency, such as green and yellow). In addition, it is possible to represent the general characteristics of each display board (for example, a restricted area for outsiders or quietly).
Once an emergency situation occurs, all of the discolored internally illuminated display boards change color to an emergency display color (for example, red) all at once and appeal to the eye that they are “very”. Thereby, even if it is a hearing impaired person, an emergency can be immediately felt.
Further, as an application example of the present claim, the discoloration can be induced by blinking the discolored internally illuminated display board along the escape route.

According to the invention of claim 6 described above, the present invention device used for emergency information transmission and evacuation guidance can be used dynamically in daily work. That is, for example, a receptionist who responds to a visitor operates the switch to cause the visitor to be guided without leaving the receptionist's seat by blinking or changing the color of the display board of the department where the visitor should be guided. Can do.
Such an effect does not only reduce the labor of the receptionist. For example, if a receptionist guides a visiting department with a visitor, the receptionist will be absent for a while. During the absence, there is no guarantee that there will be no very important visitors, and there is a possibility that undesired visitors (such as gang members and general assembly stores) will pass by. The potential effect of claim 5 for preventing such misdelivery is enormous.

The configuration of the invention device according to claim 7 is that a large number of discolored internally illuminated display boards according to claim 1 or 2 are arranged,
A touch panel depicting the layout of the large number of discolored internally illuminated display boards is provided, and touching a desired location depicted on the touch panel discolors the corresponding discolored internally illuminated display board, And / or flashing,
Alternatively, the discoloration internally illuminated display board along the path from the touch panel to a desired location is discolored or blinks.

According to the invention device of claim 7 described above, the device of the present invention, which is originally responsible for emergency notification and guidance, is used in normal times, and “to the desired location” by “guided person's own operation”. Can be guided.
Since this guidance is performed without sound at all, it is very effective in quiet facilities (for example, museums and concert halls), and is excellent as a guidance and guidance mechanism for hearing impaired persons.

According to the first aspect of the present invention, the luminous flux emitted from the LED and incident on the end face of the light guide plate is reflected by the reflection sheet and emits light on the entire surface of the light guide plate. Therefore, the required number of LEDs is less than the light emitting area. Few.
In addition, since the reflection sheet is sandwiched between the two light guide plates, both the front and back surfaces emit light.
In addition, since a full-color chip is used, the color tone can be arbitrarily changed by control by the control LSI, and it is easy to blink.
Furthermore, since the color tone and blinking are controlled by the control LSI, it is suitable for remote operation, can be operated by an automatic device such as a smoke sensor, and can be manually operated based on the will of the administrator.

  According to the invention of claim 2, both sides of the display board can emit light with the same color tone, and the color tone can be changed at the same time.

According to the invention device of claim 3,
In normal times, each of the large number of discolored internally illuminated display boards emits their own normal colors (colors other than “red” meaning emergency, such as green and yellow). In addition, it is possible to represent the general characteristics of each display board (for example, a restricted area for outsiders or quietly).
Once an emergency situation occurs, all of the discolored internally illuminated display boards change color to an emergency display color (for example, red) all at once and appeal to the eye that they are “very”. Thereby, even if it is a hearing impaired person, an emergency can be immediately felt.
Further, as an application example of claim 2, blame can be induced by blinking the discolored internally illuminated display board along the escape route.

According to the fourth aspect of the invention, when a large number of discolored internally illuminated display boards are arranged, no electrical wiring is required, so that the operation can be performed quickly and easily. In particular, when the discolored internally illuminated display board has to be moved by changing the pattern or the like, the practical value of the effect (wiring is not required) peculiar to claim 3 is felt.
Further, since the control LSI includes a wireless receiver, the discolored internally illuminated display board can be easily incorporated into the wireless LAN, and can be adapted to the IT era.

According to the invention of claim 5, since it is not necessary to wire commercial power as a power source, the installation work is easy, and in particular, the relocation can be performed quickly and easily.
Regarding the configuration and operation of claim 4, it should not be misunderstood that “power supply by solar cells is only a known technique”. The effect of the present claim that the power wiring is not required is combined with the effect of the claim 3 that the signal wiring is not required, to produce an excellent practical effect.

According to the sixth aspect of the present invention, the apparatus of the present invention used for emergency information transmission and evacuation guidance can be used dynamically in daily work. That is, for example, a receptionist who responds to a visitor operates the switch to cause the visitor to be guided without leaving the receptionist's seat by blinking or changing the color of the display board of the department where the visitor should be guided. Can do.
Such an effect does not only reduce the labor of the receptionist. For example, if a receptionist guides a visiting department with a visitor, the receptionist will be absent for a while. During the absence, there is no guarantee that there will be no very important visitors, and there is a possibility that undesired visitors (such as gang members and general assembly stores) will pass by. The potential effect of claim 5 for preventing such misdelivery is enormous.

According to the invention device of claim 7, it is possible to guide to a desired location by “operation by the guided person himself” by using the device of the present invention, which is originally responsible for emergency notification and guidance, it can.
Since this guidance is performed without sound at all, it is very effective in quiet facilities (for example, museums and concert halls), and is excellent as a guidance and guidance mechanism for hearing impaired persons.

FIG. 1 is an explanatory diagram in which an automatic detection system diagram is added to an exploded perspective view schematically illustrating an embodiment of a discoloration internally illuminated display board according to the present invention.
A reflection sheet 6 is sandwiched between the two light guide plates 5A and 5B, and LED substrates 7 are mounted on both end faces of the light guide plate.
The LED board 7 has a large number of full-color chips (commonly known as R, G, B.LED) 7a arranged therein, and is fed and controlled via a control LSI 7b. Thereby, the color tone of the full-color chip 7a can be changed or blinked.
The light beam emitted from the LED substrate 7 passes through the light guide plate and is reflected by the reflection sheet 6 to cause the light guide plate to emit light.

The light guide plate and its accessory members are housed in a transparent acrylic case 8, and letters or symbols are drawn on the acrylic case. In this example, four characters of “development manager” are drawn, but what kind of characters are drawn is arbitrary, and may be an arrow indicating an evacuation direction, for example.
In this way, the light guide plate can function as a discolored internally illuminated display plate. Further, since the two light guide plates 5A and 5B have a structure in which the reflection sheet 6 is sandwiched, both sides of this internally illuminated display plate have a display function.
When the display on only one side is sufficient, it is possible to provide only one light guide plate 5A and omit the other light guide plate 5B as an application example of FIG.

The control LSI 7 b is connected to the smoke sensor 9 via the controller 10. If comprised in this way, when the smoke sensor 9 detects a fire (smoke), the light emission color tone of a light-guide plate will be changed automatically and evacuation can be promoted.
Although not shown, the following example is also recommended as another embodiment.
Three letters “emergency exit” are drawn on the acrylic case 8 and placed near the emergency exit, and light is emitted in green during normal times. If the smoke sensor 9 detects a fire, the light emission is blinked to call attention. It is also possible to change the color within the range allowed by the relevant laws and regulations with the flashing.
Since the discoloration internally illuminated display board of the present invention further exhibits various functions, it will be described in detail below with reference to FIGS.

FIG. 2 is an example in which the present invention is applied to a department display board arranged in a corridor of a management building provided in a factory of a machine manufacturer.
A department display board showing department names such as purchasing, finance, design, technology, and patents is placed near the doorway of each section. These department display boards are comprised of the discolored internally illuminated display boards according to the present invention.
Like the Purchasing Department and the Finance Department, "Internal lighting display board, Evergreen 11, which emits green light during normal times" is placed on the door of the room where "visitors checked at the reception" may enter. And
As in the design section, engineering section, patent section, etc., the “indoor lighting display board that always emits yellow light” "Yellow 12" is listed.

As described above, the discoloration internally illuminated display panel of the present invention has a structure in which a full-color chip is controlled by a control LSI, and therefore can emit light in any color tone such as green and yellow, and change the color tone. It is also easy.
In general companies and the like, there are many cases in which the “outpatient entry prohibited area” is changed in accordance with various events, and therefore, the practical value of easily changing the color tone of the department display board is great.
Although the above is normal, when the smoke sensor 9 transmits a detection signal, all the discolored internally illuminated display boards are automatically changed to a danger display color (for example, red).

Also, for example, when a “close fire alarm” is entered from the fire department to the security guard room 18, all the department display boards (discolored internal lighting display boards) are displayed in danger display colors (red) by the switch operation of the security guards. Can be changed.
Other applications include a wide range of operations such as blinking the department display board (discolored internal lighting display board) by the switch operation of the manager 19 when the "visitor leaving request time" is reached 5 minutes before the end of business. There are uses. Although not shown, the blinking operation of the visitor leaving request can be automatically performed in conjunction with a clock by applying a known technique.

FIG. 3 is a schematic perspective view schematically showing an example in which the embodiment shown in FIG. 2 is improved.
The control LSI 7b provided on each department display board (discolored internally illuminated display board) includes a wireless receiver 12 and a solar cell 13.
Correspondingly, the controller 10 provided in the management command room 16 includes a wireless transmitter 15.
According to this example:
a. Each department display board (discolored internally illuminated display board) does not require signal wiring, and
b. Each department display board (discolored internal illumination display board) does not require power supply wiring.
For this reason, the department display board can be moved quickly and easily.

FIG. 4 is a schematic diagram showing an embodiment further different from the above, in which the discolored internally illuminated display board according to the present invention is applied to a hospital.
In the vicinity of a door where a patient can enter, such as internal medicine and pediatrics, a department display board consisting of an internal lighting display board and evergreen 11 is placed.
In the vicinity of the doors of rooms that are not suitable for patients such as operating rooms, dispensing rooms, instrument rooms, etc.
The department display board which consists of an internal lighting display board and ever yellow 12 is hung up.
On the other hand, a touch panel 17 is arranged at the reception and information center. On this touch panel, a schematic diagram of a hospital room layout is drawn, and an internal medicine, pediatrics, operating room, dispensing room, instrument room, etc. are shown.

For example, when a guidance staff tells a visitor the directions to pediatrics, touching the pediatrics on the touch panel 17 causes the pediatric display board to flash.
So, the guidance clerk should point to the path to pediatrics and tell them, “Please come to the place where the sign is shining or disappearing”.
The usage of the touch panel 17 is extensive. For example, in a nursing home where a resident including a hearing impaired person is present, this touch panel may be installed in a break room or a corridor, and the resident himself / herself may touch it. If used in this way, it is possible to provide guidance to a hearing impaired person without requiring sign language. In addition, rather than simply teaching and guiding the elderly with hearing impairments, it encourages spontaneous behavior of touching the touch panel and searching for a path on its own, so it has an excellent secondary effect of being effective in preventing dementia.
