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. As shown in Fig. 12, this illuminated mosaic panel has illuminated lamp units (3) that provide necessary display fitted into the squares (2) of a panel frame (1) formed into a grid pattern.
Blind tiles (4) are attached to the other channels to form panel surfaces.

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]

The conventional illumination lamp unit, as shown in Fig. 13,
A desired shape B is bored on the surface of the tile A to be attached and detached from the front side of the panel frame (1), and a light-transmitting light plate C such as acrylic resin is fitted therein, and the panel frame +1
Lamp units equipped with light-emitting bodies such as light-emitting diodes D may be mixed up from the rear of the display unit 1, and wiring errors may occur, and it is not easy to change the display position. For example, depending on the movement position of the illumination lamp unit, the cable may not reach all the way. 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.
There is no need for complicated wiring or connection work, and power can be easily supplied by simply attaching the illumination lamp unit to the panel frame, and the panel frame can be freely moved to the desired position or increased or decreased, eliminating the possibility of wiring errors. We have invented a power supply mechanism for illuminated mosaic panels that is safe.

Another object of the present invention is to obtain 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]

On the back of a panel frame (11) in which a checkerboard pattern was formed by vertical and horizontal walls, slots E were attached to and detached from the panel frame (1) at a certain distance from the back. then wire it with cable F and connect it to connector G.
Connected with

The present inventors have also devised the idea of using a lamp unit mounted inside the tile A [Utility Application No. 5789684, Utility Model Application No. 58-193801]. 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 fil.

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 conventional illuminated lamp units are wired using cable F, -
connection work is required.

This means that many wiring lines are placed on the back of the panel frame (1), and a signal bus (5) and a common line bus (6) are arranged along the wall of the panel frame. The signal bus and the common line bus are each connected to a power supply circuit.

On the other hand, the illumination lamp unit (3) fitted into the channel of the panel frame (1) is at least partially
) shall protrude from the back of the Some of the protrusions include
A contact 06) that contacts the signal bus (5) and a contact 07) that contacts the common line bus (6) are provided.

As a convenient mechanism for complex control, a signal bus (5) and a common line bus (6) are arranged in a direction that intersects with each other, and each bus is provided with a control means for controlling energization.

[For production]

An illuminated lamp unit (with an acrylic board or the like with the necessary display attached to the front of the panel frame (1) at the desired channel (2))
3) Insert and attach from the front of the panel frame.

When the illumination lamp unit 7 is installed, its contact 06) contacts the signal bus (5), and its contact αη 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 barrier at any position without requiring any connection work with a cable.

If the signal bus (5) and the common line bus (6) are arranged in the intersecting direction and a control means for controlling the energization of each bus is provided, the combination of energization of the vertical and horizontal buses will cause complications. control is 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. (
41, (41 is fitted to form the panel surface.

Therefore, the bus arrangement is simplified in half.

The signal bus (5) and the common line bus (6) have a constant dimension X between the back of the panel frame and the back of the panel frame (1), and dimensions X2 and X3 between the buses. must be kept constant at all times. If these dimensions X1 to x3 can be kept constant,
Each bus may be fixed to, for example, another frame separately from the panel frame (11). However, it is preferable that the bus and the 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), and a through hole (8) is bored in this boss (1a). has been done. Therefore, a plurality of buses are fixed with one bolt (9) using this through hole (8). In other words, when fixing one bolt (9) through a plurality of buses on the back side of the panel frame, the panel frame (1) and the first signal bus (5)
On the back of the cylindrical panel frame (1) with a length X between them, there is a signal bus (5) separated by a certain dimension 5) ゛ is arranged vertically in the drawing. In addition, the signal bus (5)
A common line bus (6) is disposed in the horizontal direction in the drawing at a distance of a certain distance χ3 from the common line bus (6).

If the grid of the panel frame fit is 5 rows and m columns, there will be one signal bus (5) and (5) for each m column of outlet ports on the panel frame, and a common line bus (6) will be in the n row. On the other hand, by arranging one bus for each, it becomes possible to combine different 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) are integrated through a thin insulating material (7) to the extent that they can come into contact with the same contact point. The contact portions of one bus project to the right in the longitudinal direction, and the contact portions of the other bus project to the left, and the buses are arranged along every other wall of the panel frame. In other words, the signal bus (5,) and (5,
□) is on the same plane as the common line bus (61) and (6□)
are on the same plane. This spacer QO
I, and a cylindrical spacer 0υ of length x 2 is interposed between the first signal bus (5) and the second signal bus (5)''. A spacer (b) of length x3 is interposed between the bus (5)' and the common line bus (6), and a bushing α is interposed between the common line bus (7) and the bolt head. These spacers 00), 00.02) and bushings 03) are made of insulating material, and the individual buses are insulated, but the entire bus is insulated except for the contact parts (5a) and (6a). Preferably, the whole is coated with an insulating material.

FIG. 6 shows an example of the illumination lamp unit (3) applied to a panel frame having the two signal buses (51, (51) and one common line bus (6) described above. The casing of this illuminated lamp unit has a panel frame (
A fitting part (3b) to be inserted into the hole (2) of the panel frame and a protrusion part (3c) protruding from the back side of the panel frame are formed on the back of the main body part (3a) located in the front of 1). It's there.

The width of the insertion part (3b) is equal to the inscribed dimension of the hole passage, and the upper and lower parts 1j are made narrower than the width, and a locking leg piece 04) is provided there. On the front of the main body part (3b),
The acrylic plates θ that display the necessary information are removable.

On one of the left and right sides of the protrusion (3c), there is a contact portion (
5a) and the second signal bus (5a).
A contact point 06)' which contacts the contact part (5a)' of )' protrudes across the dimension X2. In addition, the above contact ae
, αe゛ are provided on the two upper and lower side surfaces adjacent to the side surfaces, there are contacts at positions that contact the contact portions (6a) of the common line bus (6), that is, at positions spaced apart from the contact points a by a distance of dimension X3. θ'6 are provided respectively.

Therefore, the illumination lamp unit shown in FIG. 6 can be installed in any position of the panel frame by turning the entire unit up and down and half a turn, thereby allowing the first signal bus (5) and the second signal bus to be connected. Electrical connection with the bus (5)° and the common line bus (6) is possible. However, if the display surface has directionality and cannot be reversed, as shown in Figure 7, the ■ on both the left and right sides are marked with signal buses (51), (51)' to (
5n), (5n)' control means (181), (181)' to (18n),
(18n)', and common line buses (6I) to (6
control means (19) for controlling energization to each of m);
1) to (19m) are included. Each illumination lamp unit (31-,) to (3n-m) has red light emitting diode circuits (20,-,) to (20n-m), respectively.
m) and green light emitting diode circuit (21+-+)~
(2In-m) is included.

Therefore, the control means (1B, ), (181)' to (18
n), (18n)' and control means (19+) ~(
19m), it becomes possible to arbitrarily operate a desired illumination lamp unit (3) and perform complex control to freely perform red display and green display.

R in the control section (2) is a current limiting resistor, which can also be included in each illumination lamp unit.

In the above explanation, the distinction between signal buses (5□) to (5n) and (5,)' to (5n)' means switching between the first signal and the second signal, and does not necessarily mean that there is a contact point for each. It is preferable to make θe and 060'' protrude.

The illumination lamp unit (3) has a built-in illumination lamp circuit using light emitting diodes, which includes two circuits. That is, the first signal bus (5)
The first circuit is formed by the contact θe that contacts the common line bus (6) and the contact 07) that contacts the common line bus (6), and the contact 061'' that contacts the second signal bus (5)'' and the common line bus. contact 07). For example, the first circuit includes a red light emitting diode,
Assuming that the second circuit includes a green light emitting diode, the display by one illumination lamp unit can be changed to red display and green display.

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

In the figure, ■ indicates the display section, ■ indicates the control section, and the display section I includes signal buses (5,), (5+)' to (5n), (5n).
', common line buses (61) to (6m), and illumination lamp units (31-1) to (3n-m). It is not necessary that one control part 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.

For each illumination lamp unit (3) in one cellway, two
Even if there are two signal buses (5) and (5)', it is conceivable to operate 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). can. The illuminating lamp unit (3) of the embodiment shown in FIG. )", and contact points OD that can contact the common line bus (6) are provided on the four sides of the protrusion (3C). By doing this, by changing the direction of the illumination lamp UniSoto by 90 degrees,
It can be used for the first signal and for 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 a signal bus +51 on the same side of the protrusion (3C). Contact 06 touching +51'
), α6)゛ and the contact point (
I'll will be placed.

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 the control of the signal bus and the control of the common line bus.

The signal bus (5) has two stages as shown in the diagram, and is controlled by the first signal and the second signal, as well as one stage or three stages.
It may be a step. It is operated by a three-stage signal bus, that is, three types of signals.This eliminates complicated wiring on the back of the panel in illuminated mosaic panels, eliminates wiring errors, and also eliminates wiring errors due to the lack of cable length. There is no need to worry about not being able to move the panel frame to a desired position on the panel frame.

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 prevented from wobbling or misaligning. According to the invention as set forth in claim 4, which is characterized in that the illumination lamp unit receives a plurality of signals, three contacts aFA and αr1Q61'' are provided on one side of the protrusion as shown in FIG. .

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 It can be used effectively by providing it only in the area.

There is also a type of panel frame called a force/throat-free type, which is constructed by combining small rectangular frames.

Of course, the present invention can also be applied to mosaic panels of such panel frames.

[Effects of the Invention] According to the power feeding mechanism in the illuminated mosaic panel of the present invention as set forth in claim 1, there is no need to wire the illuminating lamp units, and the illuminating lamp unit can be simply mounted on the panel frame. electrically connected.

Therefore, complex displays such as lighting, turning off, and changing colors can be performed.

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