  For this reason, if one of the light emitting diodes 110 is cut off while being used as illumination, all of the four light emitting diodes 110 of the unit light emitting diode group 110A where the broken light emitting diode 110 is located do not emit light. For this reason, the length of the unit light emitting diode group 110A is a portion that does not emit light, which makes the appearance worse, and may cause a problem for continued use as a decoration.

The severable lighting device 1 is an illumination device that is arranged so as to lie mainly on the outer surface of a building, a plant, or the like, lights up a plurality of light emitters 11, and performs decoration by light emission of the light emitters. The attached insulating tube 80 can be freely bent and decorated in a free shape. The illuminating device 1 that can be cut leaves a unit of a necessary length and can be used by cutting unnecessary units. When a plurality of light emitters are cut off, the unit with the light emitters can be used. Can be cut and removed.

  As shown in FIG. 1, the lighting device 1 is provided with an insertion plug 73 for insertion into an outlet or the like at one end thereof. A rectifier 72 is provided on the power line 77 extending from the plug 73. The rectifier 72 is a power conversion device that converts (rectifies) AC power into DC power, and converts AC power supplied via an outlet into DC power for driving the light emitter.

  A DC power line 78 extending from the rectifier 72 is connected to an insulating tube 80 with a skin via an adapter 71. The DC power line 78 includes two power wires, that is, a power wire 20A and a power wire 20B, one being a positive wire and the other being a ground wire. The DC power lines 78 are connected to the two power supply wires of the unit 50, respectively, and power is supplied to each of the units 50A to 50F, and the plurality of internal light emitters 11 emit light and light up. If necessary, it is possible to control the lighting time by providing a multivibrator circuit or the like to blink the light emitter 11 or by providing a timer circuit or the like.

  Next, the configuration of the unit 50 will be described. FIG. 2 is an explanatory diagram showing the configuration of the unit of the illuminating device that can be cut in the present invention. The configuration of the plurality of units 50A to 50F of the severable lighting device 1 is the same. The unit 50 is connected to the two power wires 20A and 20B, respectively, so that the unit 50 and the adjacent unit 50 can be disconnected. An LED or a light bulb can be used as the light emitter 11, and it is sufficient that at least four light emitters 11 are provided in one unit 50, but the number of light emitters 11 may be increased as necessary. .

  The unit 50 includes a plurality of light emitter groups 60A to 60H in which a plurality of light emitters 11 are connected in parallel. In this embodiment, two light emitters 11 are connected in parallel to form a light emitter group. However, three or more light emitters 11 may be connected in parallel to form a light emitter group 60. . By connecting two or more light emitters 11 in parallel, even if one of the light emitters connected in parallel is cut off and no longer emits light, the other light emitters 11 can emit light, The current flows to the adjacent light emitter groups via the other light emitters, and the light emitters of the other light emitter groups can emit light.

  The luminous body group 60A is connected in series to the luminous body group 60B, and similarly, the luminous body group 60 is connected in series. The light emitter group 60A located at the end connected in series is connected to one of the two power supply wires (power supply wire 20A in FIG. 2), and the light emitter group 60H located at the other end connected in series. Is connected to the other of the two power wires (power wire 20B in FIG. 2). Moreover, in order to adjust the electric current value which flows into each unit, the resistor 30 can be connected in series with the light emitter group of the unit. In FIG. 2, the resistor 30A is connected between the light emitter group 60A located at the end connected in series and the power supply wire 20A. The amount of current is controlled by the resistor 30A, and the adjusted amount of current is supplied to the light emitter groups 60A to 60H connected in series.

Yes. The light emitter group 60B also has a connection point in which a plurality of light emitters 11C and 11D are connected in parallel, and this connection point is a connection in which the light emitter group 60A and the light emitter group 60B are connected in series. The connection point 12A is the same as the point. That is, at the connection point 12A, the four light emitters of the light emitter 11A, the light emitter 11B, the light emitter 11C, and the light emitter 11D can be connected at one place, and the terminals or connecting wires of the four light emitters are soldered. By connecting by attaching or the like, the connection can be made in one operation, and the connection strength can be increased. As a result, when connecting the light emitters, if the light emitters are connected in parallel (the parallel connection operation is performed twice) and then connected in series, the connection operation is required three times at a time. The connection work can be easily performed by connecting the terminals of the two light emitters at one place. Furthermore, since the number of connection points can be reduced, it is possible to reduce locations where contact failure is likely to occur, and to make contact failure difficult.

  Further, when three or more light emitters 11 are connected in parallel, the connection work can be further improved by connecting all the light emitters of two adjacent light emitter groups at one connection point. It is simple and can reduce the number of places where contact failure is likely to occur, making it difficult to cause contact failure.

The other connection points 12B to 12G are similarly connected, and in the example shown in FIG. 2, the light emitter group 60A to the light emitter group 60H are set as one unit. The number of light emitter groups 60 in the unit can be two or more.
The severable portion (indicated by the severable line 76B) is one of the two power wires of the light emitter group 60J located at the end of the adjacent unit 50C connected in series (power wire 20A in FIG. 2). ) And the other of the two power wires of the light emitter group 60H located at the other end connected in series of the unit 50A adjacent to the unit 50C (the power wire 20B in FIG. 2). Between the connection point 62B. As a result, each unit is connected to two power supply wires, so that even if other units are disconnected, power is supplied without being affected by the other units, and the light emitter can emit light. it can.

  Next, the manufacturing method of the illuminating device 1 which can be cut | disconnected is demonstrated. 3 to 5 are explanatory views showing a method for manufacturing a severable lighting device according to the present invention.

  The manufacturing process includes steps (1) to (4). FIG. 3 shows an explanatory diagram (a) in step (1) and an explanatory diagram (b) in step (2), and FIG. An explanatory view (a) in the step (3) and an explanatory view (b) in the step (4) are shown. Moreover, in FIG. 5, the modification in process (2) is shown as explanatory drawing (a), (b). 3 to 5, the left side of the drawing schematically shows a side view of the insulating tube 90 manufactured in each step when viewed from the side in the longitudinal direction, and the right side of the drawing shows the insulating tube 90 manufactured in each step. The circular sectional view which showed typically the case where it cut | disconnects by cutting line AA to FF of this is shown.

(1) As shown in FIG. 3 (a) in the step (1), first, an insulating tube 90 serving as a core is manufactured. The insulating tube 90 is a foldable solid tubular tube, is formed of a material such as paraffin or polyvinyl chloride (PVC), which is a thermoplastic resin, and has an appropriate melting temperature, for example, 45 to 90. It is made of a soft material so that it can be bent when it is melted at 0 ° C. and solidified below the melting temperature. In the tubular mold for forming the insulating tube 90, two power supply wires 20 </ b> A and 20 </ b> B are arranged in parallel at equal intervals, and the PVC is melted and flowed around at an appropriate melting temperature. Create In addition, in the side view of FIGS. 3-5, although the electric wires 20A and 20B for power supply are typically arrange | positioned up and down, as shown to sectional drawing, electric power wires 20A and 20B are arranged in parallel. To place. The arrangement position of the power supply wires 20A and 20B is to be connected to the power supply wires 20A and 20B by stripping the resin of the insulating tube 90 partially when connecting to the connection line of the light emitter later. In order to facilitate the stripping operation, it is desirable to arrange the insulating tube 90 at a portion near the outer peripheral edge or a portion near the wiring groove. Moreover, when actually arrange | positioning, as long as each of the electric wires 20A and 20B for power supply is covered and insulated with the insulation tube, it does not need to be located in parallel. Thereby, each of the electric wires 20A and 20B for power supplies can be insulated easily.
By this step, the insulating tube 90 in which the power supply wires 20A and 20B are arranged is formed. The length of the insulating tube 90 can be appropriately set according to a predetermined number of units. For example, when the length of one unit is 1 meter, when the lighting device 1 capable of cutting 100 units is formed, the unit is formed with a length of 100 meters.

  (2) Next, the hole 10 for light emitters for putting the light emitter 11 is opened at a predetermined interval in the insulating tube 90 manufactured in the step (1). As shown in FIG. 3B, the light emitter hole 10 may be a through hole that penetrates the outer periphery of the insulating tube 90 or a hole that has a bottom so as not to penetrate. The hole 10 for light emitters is formed in a columnar shape, a prismatic shape, or the like according to the shape of the LED or the like of the light emitter 11 to be inserted. By making the hole a little smaller than the size of the light emitter, when the light emitter 11 is mounted in the internal light emitter hole 10, the hole is held so as not to move due to the elasticity of the insulating tube 90. Can do.

  Further, as shown in FIG. 3B, wiring grooves 40 and 41 for connecting the light emitter 11 are formed by carving the outer periphery of the insulating tube 90 along the longitudinal direction of the outer periphery of the insulating tube 90. To do. Two wiring grooves are formed at different positions on the outer periphery of the insulating tube 90. In FIG. 3B, since the insulating tube is viewed from the side, the wiring grooves 40 and 41 are shown in overlapping positions, but as shown in the cross-sectional view, both the left and right sides in the drawing of the insulating tube. It is arranged at each position. As will be described later, the wiring grooves 40 and 41 are two grooves for mounting a part of the connection line in which every other light emitter 11 arranged in the longitudinal direction of the insulating tube 90 is connected. Yes, from the outer periphery of the insulating tube 90, it is formed into a columnar shape, a prismatic shape, or the like according to the thickness of the connecting line to be inserted. By making the groove a little smaller than the diameter of the connecting wire, it is possible to hold the wiring so as not to move due to the elasticity of the insulating tube 90 when the connecting wire is attached to the wiring grooves 40, 41. it can. Alternatively, one through hole may be provided so as to penetrate the wiring groove 40 and the wiring groove 41, and the connection lines may be attached respectively from the left and right sides of the insulating tube in the drawing. Further, the wiring groove 40 and the wiring groove 41 may be provided at different positions, and may not necessarily be provided at symmetrical positions.

In addition, the light emitter hole and the wiring groove may have various configurations. However, the light emitter and the connection line can be arranged and dimensioned so that the light emitter and the connection line can be easily mounted and held.
For example, as shown in FIGS. 5A and 5B, wiring grooves 43 for connecting the light emitters 11 are formed by cutting the insulating tube 90 along the longitudinal direction of the outer periphery of the insulating tube 90. . The wiring groove 43 has a narrow dimension so that the outer periphery of the insulating tube 90 is normally closed at the outer periphery of the insulating tube 90, and the connecting wire is expanded while manually extending the wiring inserting port when inserting the connecting wire. After the insertion, the wiring insertion port can be closed. The wiring groove 43 is formed in a tubular shape along the longitudinal direction of the insulating tube 90. Further, the light emitting hole 10B is formed at a predetermined interval so as to communicate with a part of the wiring groove 43. The hole 10B for light emitters is formed in a shape that allows the light emitters 11 to be disposed sideways. The light emitter 11 can be inserted from the wiring insertion opening of the wiring groove 43.

  Further, as shown in FIG. 5B, wiring grooves 44 for connecting the light emitters 11 are formed by cutting the insulating tube 90 into a tubular shape along the longitudinal direction of the outer periphery of the insulating tube 90. May be. The wiring insertion opening of the wiring groove 44 can be the same as that shown in FIG. Further, the light emitter holes 10 </ b> C are formed at predetermined intervals so as to communicate with a part of the wiring groove 44. The hole 10C for light emitter is formed in a shape that allows the light emitter 11 to be arranged vertically. The light emitter hole 10 </ b> C may be a through hole, or may be formed as a closed hole in the upper portion of the insulating tube in the drawing, and the light emitter may be inserted from the wiring insertion port of the wiring groove 44. Good.

  In this manner, a plurality of light emitter holes 10 and wiring grooves are formed in the insulating tube 90.
