らないという問題点がある。(Problems to be Solved by the Invention) However, the lighting tube disclosed in Japanese Utility Model Publication No. 54-4386 has a large arc when it is made of a hard material capable of maintaining the shape of the tube even if it has flexibility. Although it is possible to draw and bend, it is not possible to bend at any part, so there is no freedom to arrange it at the corner or step of the structure according to its shape, There was an inconvenience. In addition, there is a problem in that a large number of tubes of various lengths must be prepared in advance in order to eliminate a portion that cannot be dimensionally attached during construction.

配設した照明管の特徴となる管体の透光感、立体感等の
照明管としての装飾感に欠けるものがある。Even if the lead wire is a strip-shaped illuminating body, even if it can be bent at the strip portion, the small light bulb is exposed, so that it does not become a single, neat tube, and thus has a light-transmitting property. There are lamps lacking a decorative feeling as a lighting tube, such as a translucent feeling and a three-dimensional effect, which are characteristic of a lighting tube in which a small light bulb is disposed in a tube.

In a lighting tube containing a body, the tube is formed of hard plastic, and the luminous body is formed by electrically connecting in parallel between a pair of conductive wires wired in the tube, and cut at an arbitrary position. A configuration in which a translucent heat-shrinkable tube is applied to both cut portions of the above-mentioned tubular body, the cut two tubular bodies are connected in series, and both the tubular bodies are bent at the heat-shrinkable tube. Characterized in that it has a corner-folded illumination tube.

A guide cover 7 for fitting the receptacle 3 is fixedly integrated with the outside of the plug 5 so as to surround the pin 6. The receptacle 3 includes a fitting portion 3a fitted to the tube 2,
A connecting portion 3c having a hole 3b protruding from an end of the tube 2 and having a pin 6 of a plug inserted therein, and a locking arm 3d protruding outside thereof are integrally provided. The plug 5 integrally has a fitting portion 5a fitted to the tube 2 and a body portion 5b to which the guide cover 7 is fixed, and is embedded so that pins 6 protrude from both ends.

後でよい。Thus, when it is necessary to take a bent form at a desired location when mounting the lighting tube 1, as shown in FIGS. Only a portion is appropriately cut with a cutter or the like, and then a heat-resistant and transparent soft heat-shrinkable tube 10 made of, for example, fluororesin (for example, trade name Teflon) is cut from one end of the tube 2.
And the tube 10 is attached so as to straddle the tube portions on both sides of the cut portion 2a. Then, the cut portion 2a of the tube 2 is set at a predetermined angle (FIG. Then 90
゜), and the outside of the tube 10 is slightly stretched by being pulled. The heat-shrinkable tube 10 may have a diameter of 11 to 12 mm and a length of about 5 to 6 cm when the tube 2 has the above dimensions.

次いで又は同時に、熱風を吹付けて該チューブ10を熱
収縮させつつ管体２に密着させる。Then or simultaneously, the tube 10 is brought into close contact with the tubular body 2 while being thermally contracted by blowing hot air.

っ張られ状態を防止する上で好ましい。In this way, it is possible to obtain a lighting tube that is bent at a desired angle at an arbitrary position, without losing the transparency, while using a single lighting tube. In addition, the inner conductor 8 and the small light bulb 9 are reliably insulated and coated even in the corner bent portion. Note that it is preferable to set the length of the conductor 8 in advance so that the conductor 8 has some allowance in order to prevent the conductor from being pulled in the above-described corner bending.

とがなく、昼夜連続点灯しても異常を生じさせない。In addition, the illumination tube 1 according to the present invention is configured such that the heat-shrinkable tube 10 is placed over the corner-folded portion of the tube body 2 and heat-shrinks,
It protects the conducting wire 8 to the small light bulb 9 at the corner bent portion, connects and integrates the separated tube parts, and at the same time, heat-shrinks the tube 10.
Due to the heat resistance of the lamp, even if the temperature inside the illumination tube rises to about 150 ° C. at the time of lighting due to the heat generated by the small light bulb 9, it does not melt and does not cause any abnormality even if it is lit continuously day and night.

代えてピンなしのプラグ５を使用してもよい。FIG. 3 shows that the tube 2 of the illumination tube 1 is cut at a desired location, the conductor 8 is cut so as to slightly protrude from the cut tube end, and the receptacle 3 is fitted to the tube end, and at the same time, the conductor end is cut. If it is located in the receptacle 3, both the conductors do not short-circuit, the receptacle 3 closes the pipe end, and the pipe end processing is performed as it is. Alternatively, the end of the conductor is insulated, for example, a thin tube body (not shown) made of the same material as the heat-shrinkable tube 10 is applied to the end and heat-shrinked and adhered to insulate, and folded into the tube end. Alternatively, the receptacle 3 may be fitted to this tube end. Note that a plug 5 without a pin may be used instead of the receptacle 3.

The outside of the receptacle 3 where the hole 3b is not formed has the same mechanical shape. The connecting member 12 is fitted to the end of the tube, and the plug 5 of the illumination tube 1 connected to the connecting member 12 is fitted. In addition, the plug 5 without a pin may be used in the same way.
