Description

[Detailed description of the invention] [Field of industrial application] This invention displays the binary state of one signal in correspondence with the blinking of a signal lamp, and displays many states by arranging multiple signal lamps. It is to be displayed. Signal lamps typically use light emitting diodes or incandescent bulbs.

[Conventional technology] Conventionally, multiple signal lamps were placed on a panel,
The events indicated by the blinking of each signal lamp are confirmed by markings engraved near these signal lamps.

However, with such signal indicators, if you move away from the panel or the surrounding area becomes dark, the markings become difficult to see, and in the case of small devices, if the position is turned over, it becomes difficult to see the markings with just the lit lamp. Since it is not possible to distinguish between the top and bottom or the left and right, there is a problem in that it becomes difficult to tell which signal is which.

Next, the configuration of the signal indicator was changed to the third one using the conventional technology.
This will be explained using figures. 3 are signal lamps, and in FIG. 3, signal lamps 1 to 3 of the same color are arranged at equal intervals. FIG. 3a shows the normal placement, and FIG. 3b shows the inversion of FIG. 3a.

Under conditions where the engraving is difficult to see, if the two lights on the right are lit, it will indicate whether "READY" is lit as shown in Figure 3a or "HALT" as shown in Figure 3b.
It may be difficult to tell whether the light is on or not.

[Problems to be solved by the invention] This invention provides a reference lamp that lights up or blinks in relation to the signal lamp for information display, and arranges the signal lamp asymmetrically with respect to this reference lamp, so that the signal lamp is arranged asymmetrically with respect to the reference lamp. To provide a signal indicator that can identify the type of signal lamp even under conditions where the markings are difficult to see due to the relationship.

[Means for Solving the Problems] In order to achieve this object, in this invention, one or more reference lamps are turned on or flashed, and the signal lamps are arranged asymmetrically with respect to the reference lamps.

[Function] Next, the structure of the signal indicator according to this invention will be explained as follows.
This will be explained using figures. 1 in Figure 1 is a reference lamp, 2
and 3 are signal lamps, 11 is a display panel, and 12 is a controller.

The reference lamp 1 and the signal lamps 2 and 3 are connected to the controller 12.
The light turns on and off according to the command. The reference lamp 1 is always lit or blinks. In the case of blinking, it is easier to identify if the reference lamp 1 is blinked periodically. Further, the colors of the reference lamp 1 and the signal lamps 2 and 3 may be changed.

In Fig. 1, signal lamps 2 and 3 are arranged asymmetrically with respect to a reference lamp 1. In Fig. 1, each lamp is marked as shown in Fig. 3 to indicate the state of a corresponding device such as a CPU.

"HALT" indicates a stopped state, and signal lamp 2
When lit, the corresponding device is stopped; when off, it is operating.

"READY" indicates an operable state; when the signal lamp 3 is lit, the corresponding device is operable; when it is off, it is inoperable.

"COLCK" indicates that power is being supplied and is normally lit, so it is used as reference lamp 1.

In Fig. 1, if you remember the positional relationship between the signal lamps 2 and 3, you can distinguish them from any angle even though they are stamped and cannot be seen. The operating status of the compatible device can be known from the blinking of the lamps 2 and 3.

Next, the structure of another signal indicator according to this invention will be explained with reference to FIG. In FIG. 2, 4 and 5 are signal lamps, 13 is a display panel, and the rest is the same as in FIG. 1. In other words, Figure 1 shows a case where there are two signal lamps, and Figure 2 shows a case where there are four signal lamps.
There are two cases.

The signal lamps 2 to 5 in FIG. 2 are arranged at asymmetrical positions with respect to the reference lamp 1, respectively. “NMI” in Figure 2 represents interrupt input, and “RESET”
indicates a reset state.

By arranging the lamps as shown in Figure 2 and using the diameter of each lamp as a guide to the distance, you can know what the lit signal lamps indicate. Therefore,
If you remember the positional relationship, you can check the operation of the corresponding equipment by the lit signal lamp, even if the markings are not clearly visible.

In Figures 1 and 2, one reference lamp is used, but if the number of signal lamps increases or multiple rows of signal lamps are arranged, multiple reference lamps 1 may be arranged. .

[Effects of the invention] According to this invention, one or more reference lamps are lit or blinking, and a plurality of signal lamps are arranged asymmetrically with respect to the reference lamps, so that lighting is controlled based on the relationship between the lit signal lamps and the reference lamps. You can know the status of the signal lamp. Therefore, if you remember the positional relationship of the signal lamps, you can know the operating status of the corresponding equipment even when the markings are difficult to see.
