Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention bends characters into an arbitrary shape for use in illumination or the like.
The present invention relates to a flexible linear light emitting body using a light emitting diode that performs light emitting display of a figure or a pattern.

[0002]

2. Description of the Related Art In recent years, flexible linear light emitting bodies using light emitting diodes instead of neon signs or the like have been widely used as illumination materials. As shown in FIG. 12, the conventional flexible linear light-emitting body has one pair of light-emitting diodes D connected in parallel between a pair of power supply lines 1 and 2 arranged in a spiral shape, and is shown in FIG. As described above, the pair of power supply lines 1 and 2 to which these light emitting diodes D are connected are inserted into the transparent silicone tube 7 and the transparent silicone resin 8 is filled in the silicone tube 7. is there.

The flexible linear light-emitting body 20 thus constructed has a silicone tube 7 and a silicone resin 8.
Since it can be bent into any shape due to its flexibility, and moreover, since the pair of power supply lines 1 and 2 are spirally arranged,
The flexibility of this bending also increases. Then, as shown in FIG. 14, by energizing through a pair of power supply lines 1 and 2 drawn out from the ends, they are arranged at equal intervals in a flexible linear light-emitting body 20 bent into an arbitrary shape. Each light emitting diode D can emit light. Further, since the flexible linear light-emitting body 20 has a repetitive structure in which one light-emitting diode D is connected in parallel between the pair of power supply lines 1 and 2, any light-emitting diode having a desired length can be obtained. It can be cut between D and used.

In the flexible linear luminous body, as shown in FIG. 15, a pair of power supply lines 1 and 2 may be arranged in an intersecting shape, and in this case as well, the degree of freedom of bending is increased by the intersecting portion. Can be made.

[0005]

However, in the above-mentioned conventional flexible linear light-emitting body, as shown in FIG. 16, since the individual light-emitting diodes D are connected in parallel to the power source 4, this The voltage of the power supply 4 is changed to the light emitting diode D.
However, since it is necessary to prepare a power supply circuit with a special low voltage of about 2 to 3 V, the usability is deteriorated. Further, in such a circuit configuration in which the individual light emitting diodes D are connected in parallel as described above, the current flowing through each light emitting diode D changes according to the variation in the element characteristics, so that there is also a problem that the light emission luminance becomes uneven. .

In view of the above-mentioned circumstances, the present invention is to connect a plurality of light emitting diodes and a series circuit of a current limiting resistor between a pair of power supply lines. It is an object of the present invention to provide a flexible linear luminous body which is arranged and can be cut at an arbitrary length.

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 is arranged in a spiral shape or a cross shape.

An insulating tube covers the portion where the electrode is locked. Then, it is necessary to cover the portion of the last light emitting diode in each series circuit where the second electrode is locked with the insulating tube.

Since it is filled with, it is possible to easily and uniformly cover the periphery of these power supply lines with the soft synthetic resin.

According to the third aspect of the present invention, since the conductive layer is formed on the peripheral surface of the insulating tube, the electrodes of each light emitting diode are simply connected to the conductive layer of the insulating tube so that the electrodes are electrically connected. It can be connected by members. However, this conductive layer must be formed separately between electrodes that should not be connected, or the insulating tube itself must be separated.

Therefore, the flexible linear light-emitting body 20 of the present embodiment has the flexibility of the silicone tube 7 and the silicone resin 8 and the pair of power supply lines 1 and 2 spirally arranged as in the conventional case.
It becomes possible to freely bend it into an arbitrary shape. Further, since this flexible linear light-emitting body 20 has a repetitive structure in which a plurality of series circuits 3 are connected in parallel between a pair of power supply lines 1 and 2, it is possible to freely set between the light-emitting diodes D as in the conventional case. Although it is somewhat limited as compared with the case where it can be cut, it can be used by cutting it between arbitrary series circuits 3.

The flexible linear luminous body 20 having the above structure
As shown in FIG. 5, it is preferable that the feeders 1 and 2 are drawn to the outside from the vicinity of both ends to provide the connector 9. When such a flexible linear light-emitting body 20 is used, a terminal treatment is performed by fitting a tubular cap 10 having one end closed at the end. When the two flexible linear light-emitting bodies 20, 20 are connected and used, both flexible linear light-emitting bodies are provided on both sides of the connecting pipe 11 provided with a stopper at the central portion of the tubular inner diameter, if necessary. Body 2
The ends 0 and 20 are inserted, and the connectors 9 and 9 of the power supply lines 1 and 2 drawn from the vicinity of these ends are fitted and connected. Then, the connectors 9 of the power supply lines 1 and 2 drawn out from the vicinity of one of the terminal ends are fitted and connected to a connector from a power source (not shown), so that each series circuit 3 is connected via the pair of power supply lines 1 and 2. The four light emitting diodes D1 to D4 of
Let ~ D4 emit light. Alternatively, each connector 9
Plug in the connector from the power supply (not shown),
It goes without saying that blinking control may be performed individually.

As a practical size of the flexible linear light-emitting body 20 in this case, one length is 50 cm to
150 cm, the outer diameter is 10 mm to 20 mm,
It is appropriate that the light emitting diodes D are arranged at intervals of about 10 mm to 50 mm.

As described above, the flexible linear light-emitting body 20 of the present embodiment can freely bend a long shape as in the conventional case, and the flexible linear light-emitting bodies 20 are arranged at equal intervals inside. By making the light emitting diode D emit light,
It is possible to perform light emission display of characters, figures, patterns, etc. according to the bent shape. In addition, this flexible linear luminous body 2

Moreover, the series circuit 3 of the four light emitting diodes D1 to D4 and the current limiting resistor R is provided between the pair of power supply lines 1 and 2.
It is possible to make the power supply voltage to be a sufficiently high arbitrary voltage and to make the light emission luminance of each light emitting diode D uniform by connecting a large number of these in parallel.

In the above embodiment, only the case where the power supply lines 1 and 2 are arranged in a spiral shape has been described.
As shown in FIG. 5, the power supply lines 1 and 2 can be arranged in a cross shape. Further, in the above-described embodiment, as shown in FIG. 1, when the power supply lines 1 and 2 are arranged in a spiral shape, the light emitting diodes D are oriented in the same direction, but as shown in FIG. It is also possible to arrange the light emitting diode D together with the power supply lines 1 and 2 so as to be sequentially twisted.

Further, in the above-described embodiment, the case where the cathode electrode Ec and the anode electrode Ea of the two light emitting diodes D, D locked to the respective insulating tubes 5 are connected via the conducting wire 6 has been described. As shown in FIG. 8, if the insulating tube 5 covering the power supply lines 1 and 2 has the conductive layer 12 formed on the outer periphery, the use of such a conductive wire 6 can be omitted. In other words, insulation tube 5

The soldering work in the manufacturing process of 0 can be simplified.

Further, in the above embodiment, the flexible linear light-emitting body 20 using the pair of positive and negative power supply lines 1 and 2 is used.
However, as shown in FIG. 11, one may be added to the negative side to provide two power supply lines 2a and 2b. In this case, the series circuit 3a is connected in parallel between the pair of positive and negative power feed lines 1 and 2a, and the series circuit 3b is connected in parallel between the pair of positive and negative power feed lines 1 and 2b. Then, these two negative power supply lines 2 a and 2 b are connected to the negative electrode of the power supply 4 via the switching circuit 13. Therefore, while the switching circuit 13 is connected to the power supply line 2a side, the series circuit 3
Since only a is turned on and only the series circuit 3b is turned on while it is connected to the power supply line 2b side, the switching circuit 13 can perform blinking control. Although not shown in the figure, for example, one of the power supply lines 2 a is drawn out from the middle of the flexible linear light-emitting body 20 to the outside,
It is also possible to control a independently and perform blinking control.
Here, the case where one power supply line is added to the negative side has been shown, but it is also possible to provide two or more positive or negative power supply lines. These three or more feeder lines are, for example, 3
It may be arranged in a quadruple or other spiral shape.

Further, in the above embodiment, the electrodes Ec and Ea are used.
Although the terminals T1 and T2 and the terminals T1 and T2 are locked and electrically connected by soldering, caulking or another method may be used. Further, the polarity of each light emitting diode D is not limited to the orientation of the above embodiment.

Further, in the above embodiment, the silicone tube 7 has a circular cross section, but the silicone tube 7 may have an elliptical or polygonal cross section. Instead of using such a silicone tube 7, a soft synthetic resin such as a translucent silicone resin 8 may be directly covered.

Can be set to an arbitrary voltage, so that it is not necessary to prepare a special low-voltage power source, which improves usability. Further, since the current flowing through the light emitting diode is adjusted by the current limiting resistance, each light emitting diode of the flexible linear light emitting body can be made to uniformly emit light.

Moreover, each light emitting diode connected in series is
Since each one is arranged in a ladder shape between the pair of power supply lines, each light emitting diode can be arranged at equal intervals in the length direction in the flexible linear light emitting body as in the conventional case. Also,
