Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] Illuminated mosaic panels, which are mainly used as display panels for power distribution panels and control panels, are known. In this illuminated mosaic panel, as shown in Fig. 12, illuminated lamp units 3 for making necessary displays are fitted into the squares 2 of a panel frame 1 formed into a grid pattern, and the other squares are A panel surface is constructed by attaching blind tiles 4.

The illumination lamp unit 3 has a light emitting body such as a light emitting diode inside thereof. The present invention relates to a mechanism that can easily supply power to these illumination lamp units.

[Conventional technology]

As shown in FIG. 13, a conventional illuminated lamp unit has a desired shape B formed on the surface of a tile A that is attached and detached from the front surface of a panel frame 1, and a light-transmitting illuminating plate made of acrylic resin or the like is inserted into the surface of the tile A. At the same time, a lamp unit E provided with a light emitting body such as a light emitting diode D is attached to and detached from the panel frame 1 from the rear of the panel frame 1. The lamp unit E is wired with a cable E and connected with a connector G.

In addition, the present inventors proposed the idea of using a lamp unit installed in tile A [Utility Application No. 57-89684].
No. 1938-01] was also devised. This allows the entire illumination lamp unit to be pulled out in front of the panel frame.

[Problem to be solved by the invention]

In the conventional illumination lamp unit shown in FIG. 13, installation and removal operations must be performed from both the front and rear sides of the panel frame 1.

On the other hand, when the lamp unit is mounted inside the tile, the entire lamp unit can be pulled out to the front of the panel frame, making the work easier.

However, in any case, since the conventional illumination lamp unit is wired using cable F, connection work is required for each connection. This means that many wires are mixed in the back of the panel frame 1, which may cause wiring errors, and it is not easy to change the display position. For example, depending on the position to which the illumination lamp unit is moved, the cable may not be able to reach the destination. Additionally, when adding a new illumination lamp unit, new wiring is required.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and does not require troublesome wiring or connection work, and can easily be brought into a power supply state by simply mounting the illuminating lamp unit on the panel frame. This invention has invented a power supply mechanism for an illuminated mosaic panel in which the frame can be freely moved to a desired position, increased or decreased, and there is no risk of wiring errors.

Another object of the present invention is to provide a power supply mechanism that is convenient for controlling complex panel displays such as turning on, turning off, and changing the lighting of a large number of illumination lamp units.

[Means to solve the problem]

A signal bus 5 and a common line bus 6 are installed on the back of the panel frame 1 in which a checkerboard is formed by vertical and horizontal walls in a direction along the wall of the panel frame at a fixed distance from the back. Place. The signal bus 5 is connected to one electrode of the power supply circuit, and the common line bus 6 is connected to the other electrode of the power supply circuit.

On the other hand, at least a portion of the illumination lamp unit 3 fitted into the channel of the panel frame 1 protrudes from the back surface of the panel frame 1. A contact 16, which is one terminal forming an illumination lamp circuit and comes into contact with the signal bus 5, is provided on a part of the protrusion;
A contact point 17, which is the other terminal forming the illumination lamp circuit and comes into contact with the common line bus 6, is provided.

Signal bus 5 is a convenient mechanism for complex control.
and a common line bus 6 are arranged in the intersecting direction, and each bus is provided with a control means for controlling energization.

[Effect]

An illumination lamp unit 3 with an acrylic plate with a necessary display attached to the front is inserted into a desired hole 2 of a panel frame 1 from the front of the panel frame.

When the illuminated lamp unit is installed, its contact 1
6 contacts the signal bus 5, and the contact 17 contacts the common line bus 6. Therefore, an energizing circuit is formed by the signal bus, the illumination lamp unit, and the common line bus. In this way, the illumination lamp unit 3 becomes operational immediately after being attached to the cell wall at any position, without requiring any connection work with a cable.

By arranging the signal bus 5 and the common line bus 6 in the intersecting direction and providing a control means for controlling the energization of each bus, complicated control can be achieved by combining the energization of the vertical and horizontal buses. becomes possible.

〔Example〕

Embodiments of the power supply mechanism in the illuminated mosaic panel of the present invention will be described below with reference to the accompanying drawings.

As shown in Fig. 1, each square 2 of the panel frame 1, which is formed into a grid pattern by vertical and horizontal walls, is equipped with illuminated lamp units 3, 3 and blind tiles 4, 4 for providing the necessary display. Insert to form the panel surface.

The back of panel frame 1 has a certain dimension x ₁ from the back.
A signal bus 5 is disposed at a distance from the signal bus 5, and another signal bus 5' is disposed at a constant distance _X2 in the vertical direction in the drawing. Also, a certain dimension from the signal bus 5'
A common line bus 6 is arranged horizontally in the drawing across _X3 .

Assuming that the grid of the panel frame 1 has n rows and m columns, the signal buses 5 and 5' are connected to a total of m buses for each wall interval in the column direction forming the panel frame, and the common line bus 6 By arranging a total of n buses for each wall pitch in the row direction that forms the cross-section, it is possible to combine signal buses and common line buses for all the cross-sections. . However, in the illustrated embodiment, the signal buses 5, 5' and the common line bus 6
In this example, two buses are stacked one on top of the other with a thin insulating material 7 interposed between each bus. One of the two superimposed buses has a contact part that contacts the contact of the illumination lamp unit 3 on either the left or right side edge, and the other bus of the two superimposed buses has a contact part that contacts the contact of the illumination lamp unit 3. A contact portion that comes into contact with is formed on the other side edge of either the left or right side. Such a bus is designated as signal bus 5,
5' and a common line bus 6, and are arranged every two pitches between the walls forming the cell wall 2 of the panel frame 1. This simplifies the bus arrangement in half.

The signal bus 5 and the common line bus 6 have a constant dimension X ₁ between the back of the panel frame 1 and the back of the panel frame 1, and a dimension X ₂ between the buses.
It is necessary that X ₃ is always held constant. As long as these dimensions X ₁ to _{X 3} can be kept constant, each bus can be separated from the panel frame 1 by
For example, it may be fixed to another frame. However, it is preferable that the bus and panel frame are fixed integrally.

FIG. 5 shows an example of the fixing structure between the panel frame and the bus.

A cylindrical boss 1a is integrally molded at the intersection of the vertical wall and the horizontal wall of the panel frame 1.
A through hole 8 is bored in this boss 1a. Therefore, using this through hole 8, a plurality of buses are fixed with one bolt 9. That is, when one bolt 9 is passed through and fixed to a plurality of buses on the back side of the panel frame, a cylindrical spacer 10 of length X ₁ is inserted between the panel frame 1 and the first signal bus 5.
Furthermore, a cylindrical spacer 11 having a length of X ₂ is interposed between the first signal bus 5 and the second signal bus 5'. Further, a spacer 12 having a length of X ₃ is interposed between the second signal bus 5' and the common line bus 6, and a bush 13 is interposed between the common line bus 7 and the bolt head. . In this way, at the back of the panel frame 1, a certain dimension X ₁
The signal buses 5, 5' and the common line bus 6 are fixed while maintaining the signals _.about.X3 . At this time, spacers 1 are used to maintain the insulation state between each bus.
0, 11, 12 and the bush 13 are made of insulating material, and the bolts 9 are passed through so as not to come into contact with the bus. In the illustrated embodiment, all of the signal buses 5, 5' and the common line bus 6 are coated with an insulating material except for the contact portions 5a, 5a', 6a.

FIG. 6 shows the two signal buses 5, 5' mentioned above.
This shows an example of an illumination lamp unit 3 applied to a panel frame having one common line bus 6. The casing of this illumination lamp unit has a fitting part 3b inserted into the hole 2 of the panel frame at the back of the main body part 3a located in front of the panel frame 1.
A protrusion 3c is formed that protrudes from the back surface of the panel frame. The width of the fitting portion 3b is approximately equal to the inscribed dimension of the cell passage, the top and bottom widths are narrower than the width, and a leg piece 14 for locking is provided here. An acrylic plate 15 for displaying necessary information is detachably attached to the front surface of the main body portion 3b.

On one of the left and right side surfaces of the protruding portion 3c, a contact 16 that contacts the contact portion 5a of the first signal bus 5 when fitted into the panel frame, and a contact portion of the second signal bus 5' are provided. The contact point 16' that contacts 5a' has the dimensions
Protruding across the X ₂ . In addition, the contact 16,
Contacts 17 are provided on the upper and lower two side surfaces adjacent to the side surface on which 16' is provided, at positions that contact the contact portions 6a of the common line bus 6, that is, at positions spaced apart from the contact 15' by a distance of X ₃ . It is being

Therefore, the illumination lamp unit shown in FIG. 6 can be installed in any position of the panel frame by turning the whole unit up and down and half a turn to connect the first signal bus 5 and the second signal bus 5. Electrical connection with the common line bus 5' and the common line bus 6 becomes possible. However, if the display surface has directionality and cannot be reversed, it is preferable to have contacts 16 and 16' projecting from both left and right sides, respectively, as shown in FIG.

The illumination lamp unit 3 includes a built-in illumination lamp circuit using light emitting diodes, which includes two circuits. That is, the first circuit is formed by the contact 16 that contacts the first signal bus 5 and the contact 17 that contacts the common line bus 6, and the contact 1 that contacts the second signal bus 5'.
6' and the contact 17 of the common line bus. For example, if the first circuit includes a red light emitting diode and the second circuit includes a green light emitting diode, then 1
The display by the two illumination lamp units can be changed to red or green.

FIG. 11 is a circuit diagram showing an example of controlling an illumination lamp unit having the above two circuits.

In the figure, the display section indicates the control section, and the display section includes signal buses ₅₁ , ₅₁ ' to 5n, 5n', common line buses ₆₁ to 6m, and illumination lamp unit _31-1.
~3 nm included. On the other hand, the control unit includes control means 18 1 , 18 ₁ ′ to 18n, which control energization to each of the signal buses 5 ₁ , ₅ 1 ′ to 5n, _5n ′.
18n′, and control means 19 ₁ to 19 for controlling energization to each of the common line buses 6 ₁ to 6m.
m is included. Each illumination lamp unit 3 _1-1 to 3n-m includes red light emitting diode circuits 20 _1-1 to 20n-m and green light emitting diode circuits 21 _1-1 to 21n-m, respectively.

Thus, the control means 18 ₁ , 18 ₁ ′ to 18n,
By combining 18n' and the control means ₁₉₁ to 19m, it becomes possible to arbitrarily operate the desired illumination lamp unit 3 and to perform complex control to freely perform red display and green display.

The control section R may be a current limiting resistor and may be included in each illumination lamp unit.

In the above description, the distinction between the signal buses 5 ₁ to 5n and 5 ₁ ' to 5n' means switching between the first signal and the second signal, and one does not necessarily have to be red and the other green. . For example, the first signal may display a mixture of red and green, and the second signal may display a mixture of red and green in other combinations. It is also possible to use other color combinations or display formats using the same color, for example, by changing the brightness.

Even if there are two signal buses 5 and 5' for the illumination lamp unit 3 in one cellway, it is conceivable to operate it only by the signal from one of the signal buses. . In this case, the internal diode circuit may be connected in this way, but it is also possible to provide the illumination lamp unit 3 itself with a contact that contacts only one of the signal buses 5 and 5'. The illumination lamp unit 3 of the embodiment shown in FIG. 8 has a contact 16 that contacts the signal bus 5 on one side of the protrusion 3c, and a contact 1 that can contact the signal bus 5' on the other adjacent side.
6', and contacts 17 that can come into contact with the common line bus 6 are provided on the four sides of the protrusion 3c. In this way, by changing the direction of the illumination lamp unit by 90 degrees, it can be used for the first signal and the second signal.

Of course, both the signal bus 5 and the common line bus 6 may be in the vertical direction, and the common line bus and the signal bus may be in the same direction. As shown in FIG. 9, the illumination lamp unit in this case has contacts 16 and 16' that contact the signal buses 5 and 5' and a contact 17 that contacts the common line bus 6 on the same side of the protrusion 3c. That will happen.

However, when the signal bus and the common line bus are in the same direction, control will probably be provided on either the signal bus or the common line bus. That is, by providing the signal bus 5 and the common line bus 6 in a direction that intersects with the signal bus 5, complex display changes can be made by combining control of the signal bus and control of the common line bus.

The signal bus 5 has two stages as shown in the figure, and the first
In addition to being controlled by the signal and the second signal, the control may be performed in one stage or in three stages. An illuminated lamp unit operated by a three-stage signal bus, that is, three types of signals, has three contacts 16, 16', and 1 on one side of the protrusion, as shown in FIG.
6″ is provided.

The signal bus and common line bus according to the present invention described above may be provided over the entire surface at the back of the panel frame, but the portion that may be used as an illuminated display surface may be It can be used effectively by providing it only in the area.

In addition, the panel frame is called a cut-free type,
Some panel frames are constructed by combining small rectangular frames. Of course, the present invention can also be applied to mosaic panels of such panel frames.

〔Effect of the invention〕

According to the power supply mechanism in the illuminated mosaic panel of the present invention as set forth in claim 1, there is no need to conduct wiring for each illuminating lamp unit, and electrical connection can be established simply by mounting the illuminating lamp unit on the panel frame. .

This eliminates complicated wiring on the back of the panel in illuminated mosaic panels and eliminates wiring errors, as well as the inability to move the illuminated lamp unit to the desired position on the panel frame due to insufficient cable length. There is no need to worry.

According to the second aspect of the invention, the number of buses disposed on the back of the panel frame can be reduced in appearance, and the bus arrangement can be prevented from becoming complicated. It also has the practical benefit of increasing the strength of the bus structurally.

According to the third aspect of the invention, power can be supplied to the illumination lamp unit at any position by a combination of vertical and horizontal buses. By fixing the signal bus and the common line bus to the panel frame while keeping them in an insulated state at a two-dimensional intersection, the mechanical strength of the entire bus is increased, and the bus is free from wobbling and positioning. Eliminate the possibility of misalignment.

According to the fourth aspect of the invention, complicated displays such as turning on, turning off, and changing colors can be performed using a plurality of signals.

According to the invention set forth in claim 5, complex control of the illumination lamp unit can be performed efficiently.
