In the lighting devices shown in these figures, the plurality of light emitting diodes 1 connected to the power supply device 3 are energized from the power supply device 3 to the light emitting diodes 1 to emit light.

In the power supply device 3 of the lighting device of FIG. 1, connecting portions 5 for connecting the pair of leads 2 are arranged on both sides of the insulating portion 4. The connection section 5 includes an elastic holding section 6 that can pass through and hold the lead 2 of the light emitting diode 1. The elastic holding portion 6 includes a conductive portion 7 that is electrically connected to the lead 2 that is passed through. In this lighting device, the leads 2 of the plurality of light emitting diodes 1 pass through the elastic holding portion 6 of the connection portion 5 along the insulating portion 4 and are connected to the power supply device 3, and the light emitting device to which the power supply device 3 is connected is connected. Lights when diode 1 is energized.

[0045] The insulating part 4 is provided between the pair of leads 2 to prevent the lead 2 of the light emitting diode 1 from short-circuiting. The insulating part 4 shown in the figure is an insulating wall 4A. The insulating wall 4A is formed by molding an insulating material such as plastic into a plate shape. In the lighting device shown in the figure, a conductive wire 8 is fixed to both sides of an insulating wall 4A, and a conductive tape 9 having a predetermined width is fixed to the surface of the conductive wire 8 so as to be in contact with the conductive wire 8. A pair of conductive wires 8 fixed to both sides of the insulating wall 4A are connected to a DC or AC power supply, and are connected to a conductive portion 7 of the elastic holding portion 6 via a conductive tape 9. The lighting device that connects the conductor 8 to the DC power supply turns on the light emitting diode 1 continuously. The lighting device that connects the conductor 8 to the AC power source turns on the light-emitting diode 1 in half an AC cycle.

The elastic holding portion 6 is made of a synthetic resin foam or a rubber-like elastic body so as to pass through and hold the lead 2 of the light emitting diode 1 here.

The elastic holding part 6 in the figure has a conductive layer 19 as the conductive part 7 provided inside. In this structure, since the conductive portion 7 does not appear on the surface of the elastic holding portion 6 that passes through the lead 2, short-circuiting does not occur even when the conductor comes into contact with the surface.

[0048] The conductive portion of the synthetic resin foam or rubber-like elastic body may be provided by applying a conductive paint. The conductive paint is a paint obtained by adding a conductive powder to a binder and curing the binder to realize conductivity. The conductive powder added to the conductive paint is a metal powder or a carbon powder. The metal powder is a powder of nickel, aluminum, copper, Shinchu or the like. The conductive paint can reduce the electric resistance in the cured state by increasing the amount of metal powder or carbon powder added. The binder of the conductive paint is liquid or paste in an uncured state. A conductive powder is added to a liquid or paste-like binder and applied to the surface of a synthetic resin foam or rubber-like elastic body. The binder solidifies upon curing and has a low electrical resistance due to the added conductive powder. The conductive portion provided by applying the conductive paint can reduce the electric resistance by increasing the number of times the conductive paint is applied. Further, the electric resistance in the cured state can be reduced by increasing the amount of the conductive powder contained in the conductive paint.

In the above embodiment, the insulating portion 4 is used as the insulating wall 4A. The power supply device 3 has a feature that the pair of leads 2 can be reliably insulated by the insulating wall 4A. However, the insulating part does not necessarily need to be an insulating wall. Although not shown, the insulating portion may be an insulating groove or a non-conductive portion provided between the conductive portions electrically connected to the pair of leads. For example, the power supply device may be configured such that a conductive layer provided inside the elastic holding portion is divided by an intermediate groove to form an insulating groove, or a plurality of rows of conductive portions are provided inside the elastic holding portion to provide an insulating groove. The non-conductive part, which is the part, can be an insulating part.

The elastic holding portion 10 holds the light emitting diode 1 by elastically holding the lead 2 passing therethrough. Further, the elastic holding portion 10 It has a conductive portion 7 electrically connected to the lead 2 of the light emitting diode 1 through which it passes.

It is arranged. The insulating wall 4A is provided with a conductive wire 8 and a conductive tape 9 on both sides, similarly to the insulating wall 4A of FIG. The side wall 11 is a surface of an insulating plate made of plastic or the like, and the conductor 8 and the conductive tape 9 are fixed to the surface facing the insulating wall 4A. In the power supply device 3, a conductive tape 9 fixed to the surface of the insulating wall 4A and the side wall 11 is used as a conductive portion 7 connected to the lead 2.

The groove member 12 is manufactured by molding a hard material such as plastic that can be elastically deformed, or is formed by drawing a metal or the like or by press molding to form a groove. The groove member 12 is provided with an intermediate ridge 12B that is in contact with the surface of the side wall 11 and presses the side wall 11 by integrally molding the opposing surface of the continuous groove 12A. Further, in the groove member 12 shown in the figure, a holding ridge 12C for holding the light emitting diode 1 is integrally formed at the opening of the continuous groove 12A in order to sandwich the light emitting diode 1 from both sides and hold it. Set it up. The side wall 11 is fixed to the intermediate ridge 12B, and the insulating wall 4A is fixed to the bottom of the continuous groove 12A.

In the lighting device having this structure, as shown in the figure, the lead 2 of the light emitting diode 1 is inserted into the elastic holding portion 10 such that the lead 2 of the light emitting diode 1 straddles both sides of the insulating wall 4A. In this way, the plurality of light emitting diodes 1 are connected along the insulating wall 4A. In the light emitting diode 1 to be connected, the lead 2 is inserted into the elastic holding portion 10 of the connection portion 5. In this state, the light emitting diode 1 connected to the power supply device 3 is sandwiched between the conductive portions 7 made of the conductive tape 9 provided on the opposing surfaces of the insulating wall 4A and the side wall 11, and is supplied with electricity through the conductive portion 7.

The conducting wires 8 connected to the conductive tape 9 provided on the opposing surfaces of the insulating wall 4A and the side wall 11 are electrically connected to each other and connected to a power supply. Therefore, the light emitting diode 1 held by the elastic holding portion 10 is lit by bringing the lead 2 into contact with the conductive tapes 9 provided on both sides of the insulating wall 4A and supplying electricity through the lead 2.

The groove 12 shown in FIG. 2 has a shape extending linearly, so that a plurality of light emitting diodes 1 can be mounted continuously in the direction in which the groove 12 extends. However, the groove member may be formed by cutting the groove member 12 shown in FIG. This groove material, for example, One light emitting diode is held by one groove material. The groove material with the shortened overall length is easy to elastically deform the side surface, so when mounting a light-emitting diode, it has the advantage that the elastic clamping portion is widely opened and the lead can be easily inserted. Further, since the groove members individually hold the light emitting diodes, they have a feature that when the light emitting diodes are mounted, they can be mounted without affecting the sandwiching state of the adjacent light emitting diodes. For this reason, a plurality of light emitting diodes can be efficiently mounted. The groove members for individually mounting the light emitting diodes, for example, can be connected to a linearly extending guide member to integrally connect the plurality of light emitting diodes. The guide member can be connected by, for example, providing a linear elastic holding portion and fitting the elastic holding portion into a connection groove provided in the groove material. This structure has the feature that the connection position between the groove member and the guide member can be freely changed. However, the groove member and the guide member can be connected by another fitting structure or locking structure, or by bonding and screwing. Further, by forming the guide member into a desired shape, a plurality of light emitting diodes can be arranged in a desired shape. Also, by changing the direction in which the groove member is connected to the guide member in various ways, it is possible to freely adjust the irradiation direction of the light emitting diode. However, two or more light emitting diodes can be installed in one groove.

Electricity is applied to the holding layer 17.

In the power supply device 3 of FIG. 12, a metal wire 24 is sewn and fixed to the surface of the front side elastic holding layer 16 and the back side elastic holding layer 17. The structure in which the metal wire 24 is sewn can be fixed very easily by sewing with a sewing machine, for example, using the lower thread as the metal wire 24 and the upper thread as the insulating thread material 25. In particular, as shown in the figure, the tension of the metal wire 24 as the lower thread is made stronger than the thread material 25 as the upper thread, so that the metal wire 24 can be ideally wired without breaking. However, the structure in which the metal wire is sewn may be such that the lower thread is an insulating thread material and the upper thread is a metal wire, or both the lower thread and the upper thread are metal wires. For example, natural fiber, plastic fiber, or the like can be used for the insulating thread material 25. As described above, the structure in which the metal wires 24 are sewn has a feature that the metal wires 24 can be extremely easily fixed at predetermined positions of the front side elastic holding layer 16 and the back side elastic holding layer 17. However, the metal wire can be adhered and fixed to the surfaces of the front side elastic holding layer and the back side elastic holding layer, or can be fixed with a connector.

I do. This is to prevent the leads 2 of the light emitting diode 1 passing through the front side elastic holding layer 16 and the back side elastic holding layer 17 from simultaneously contacting the metal wires 24 located on both sides of the insulating layer 18. . For example, when the metal wires located on both sides of the insulating layer are located at positions facing each other, the power supply is short-circuited when the leads of the light emitting diode that passes through to the back side elastic holding layer simultaneously contact the two metal wires. Further, if the distance between the metal wires located on both sides of the insulating layer is small, the light emitting diode may be in a state where the pair of leads of the light emitting diode passing through the front side elastic holding layer and the back side elastic holding layer are both in contact with the metal wire. When the power is supplied to the LED, the LED may break down. In order to prevent these adverse effects, the distance (D) between the metal wire 24 provided on the front-side elastic holding layer 16 and the metal wire 24 provided on the back-side elastic holding layer 17 must be equal to that of the light emitting diode 1. It should be larger than the distance (d) between the pair of leads 2.

The interval (D) between the metal wires 24 is an interval in a projection view from the insertion direction of the light emitting diode 1 as shown in FIG. 14, and as shown in FIG. The distance between the metal wire 24 disposed and the metal wire 24 disposed on the back side elastic holding layer 17 is the closest to each other. In FIG. 14, metal lines 24 provided on the front side elastic holding layer 16 are indicated by chain lines, and metal lines 24 provided on the back side elastic holding layer 17 are indicated by dashed lines. In a state where the interval (D) between the metal wires 24 is larger than the interval (d) between the leads 2, as shown in FIG. Also, the pair of leads 2 of the light-emitting diode 1 passing through the front side elastic holding layer 16 and the back side elastic holding layer 17 do not come into contact with the metal wire 24 at the same time. ,. Therefore, power can be safely supplied while protecting the power supply and the light emitting diode 1. The distance (D) between the metal wires 24 disposed on both sides of the insulating layer 18 is appropriately determined by the distance (d) between the leads 2. When the distance (d) is 1.2 times or more, preferably 1.5 times or more, and more preferably 2 times or more, the above-mentioned adverse effects can be effectively prevented.

Further, the power supply device 3 shown in FIG. 15 has a frame 26 disposed on the peripheral edge. Frame 26 Are disposed in a state where the front side elastic holding layer 16 and the back side elastic holding layer 17 stacked on both sides of the stacked insulating layer 18 are insulated. The frame 26 shown in the figure is disposed so as to cover the peripheral edge of only the outer peripheral surfaces of the front side elastic holding layer 16 and the back side elastic holding layer 17. In this manner, the power supply device 3 whose peripheral portion is covered by the frame 26 is, as shown in the figure, arranged on the metal wire 24 provided on the front side elastic holding layer 16 and the back side elastic holding layer 17. And the metal wires 24 can be arranged at positions facing each other. Since the lead 2 of the light emitting diode 1 cannot pass through the portion of the frame 26, the lead 2 of the light emitting diode 1 passed through the backside elastic holding layer 17 is provided on both sides of the insulating layer 18. This is because the line 24 is not touched at the same time. In addition, the power supply device having the frame body 26 at the periphery has a feature that, when the metal wire 24 is sewn, the appearance of the thread material 25 as the upper thread can be prevented, so that the appearance can be improved.

Further, as shown in FIGS. 16 and 17, the power supply device 3 connects the auxiliary electrode 27, and supplies the power from the auxiliary electrode 27 to the front-side elastic holding layer 16 and the back-side elastic holding layer 17. Can supply power S. As shown in FIG. 17, the auxiliary electrode 27 can be inserted from the back surface side and can be arranged with good appearance without being exposed on the front surface side. However, the auxiliary electrode can be inserted and arranged from the front side. The power supply device 3 including the auxiliary electrode 27 can supply power from the auxiliary electrode 27 to the light emitting diode 1 mounted near the auxiliary electrode 27, so that the current flowing through the light emitting diode 1 is increased, There is a feature that can be brightly lit. In particular, the lighting device may have a partial difference in brightness depending on the number and arrangement of the mounted light emitting diodes. At this time, by connecting the auxiliary electrode to a part that is lit darkly, this part can be lit effectively and brightly.

The auxiliary electrode 27 shown in the figure has a pair of electrodes. This electrode is a conductive rod or plate and is connected to a power supply via a lead 28. The pair of electrodes are electrically connected to the front side elastic holding layer 16 and the back side elastic holding layer 17, respectively. One electrode of the auxiliary electrode 27 penetrating through the backside elastic holding layer 17 and passing through and connected to the frontside elastic holding layer 16 is an insulating electrode 27A. The insulating electrode 27A insulates a penetrating portion of the back side elastic holding layer 17 as an insulating portion 27a, and does not insulate a tip end penetrating the front side elastic holding layer 16. This insulating electrode 27A covers the surface of the electrode with an insulator such as plastic, Alternatively, an insulating material is applied to the surface of the electrode, or an insulating tube is inserted through the electrode to provide the insulating portion 27a. The distal end of the insulating electrode 27A can be electrically connected to the front side elastic holding layer 16 while being insulated from the back side elastic holding layer 17 by the insulating portion 27a. The insulating electrode 27A that penetrates the back side elastic holding layer 17 and enters the front side elastic holding layer 16 is electrically connected to the front side elastic holding layer 16 and is inserted into the back side elastic holding layer 17. The electrode 27B is electrically connected to the back side elastic holding layer 17. The auxiliary electrode 27 energizes the front side elastic holding layer 16 and the back side elastic holding layer 17 to energize the light emitting diode 1 mounted thereon.

However, the auxiliary electrode does not necessarily need to be a conductive rod or plate, as shown in FIGS. 18 and 19, by exposing the conductive portion of the electric wire 29 whose surface is insulated and covered. Can be substituted for the electrode. A wiring cable is suitable for the electric wire 29. For the distribution cable, for example, a two-core cable or a coaxial cable can be used. As shown in FIG. 18, the two-core cape-notch has one core wire 29A penetrated through the back side elastic holding layer 17 in an insulated state and is electrically connected to the front side elastic holding layer 16, and the other core wire 29B is connected to the back side. Connected to elastic holding layer 17. The core wire 29A connected to the front-side elastic holding layer 16 is insulated from the back-side elastic holding layer 17 by the covering portion 29a so as not to be electrically connected to the back-side elastic holding layer 17. As shown in FIG. 19, the coaxial cable is electrically connected by inserting the center core wire 29C into the front-side elastic holding layer 17 to expose the outer conductor 29D on the outside and electrically connecting to the rear-side elastic holding layer 17. I do. The center core wire 29C is insulated from the backside elastic holding layer 17 by the inner covering portion 29c so as not to be electrically connected to the backside elastic holding layer. As described above, the electric wire having the core wire insulatingly coated can ideally be electrically connected to the front side elastic holding layer and the back side elastic holding layer by adjusting the lengths of the exposed portion and the insulating portion. . However, as the electric wire for providing the auxiliary electrode, a wiring cable other than a two-core cable or a coaxial cable can be used, or an electric wire other than the wiring cable can be used.

Further, as shown in the plan view of FIG. 20, the power supply device 3 can be divided into a plurality of regions, and the auxiliary electrodes 27 can be connected to these regions. An auxiliary electrode 27 is connected to each region via a lead wire 28 to supply power. The auxiliary electrode 27 provided in each region may have the above-described structure. Further, the power supply device 3 shown in FIG. The power supply to the auxiliary electrode 27 connected to each area is controlled by the control circuit 30 so that the lighting of the light emitting diode mounted in each area can be controlled. The power supply device 3 shown in the figure is divided into a plurality of areas (six areas in the figure), and the control circuit 30 controls the power supplied to each area. In the power supply device 3 having this structure, the control circuit 30 controls the energization of the auxiliary electrodes 27 connected to the respective regions, so that the light emitting diodes mounted in the desired regions can be brightly lit. Therefore, the power supply device 3 can turn on the light-emitting diodes mounted in each area on a region basis and display different information on a region basis. Further, the power supply device 3 can also control the blinking of the light emitting diode for each area, and display in a different lighting state for each area. Further, the power supply device can display moving images by increasing the number of areas to be divided and controlling the blinking of the light emitting diodes arranged in each area.

[0085] As described above, the power supply device 3 including the auxiliary electrode 27 partially supplies light from the auxiliary electrode 27 in accordance with the number and arrangement of the light emitting diodes to be mounted, so that the difference between light and dark is partially obtained. Can be effectively prevented, and the whole can be uniformly lit. In addition, by intentionally supplying power locally to the portion where the auxiliary electrode 27 is provided, a light emitting diode near the auxiliary electrode 27 is provided. Can be turned on brighter than the surroundings to bring it to various display states.

[0086] The insulating layer 18 prevents the front side elastic holding layer 16 and the back side elastic holding layer 17 from being short-circuited. The insulating layer 18 needs to penetrate one lead 2 of the light emitting diode 1. Therefore, the insulating layer 18 is made of a synthetic resin foam or a rubber-like elastic body so that the lead 2 can be inserted.

The surface-side elastic holding layer 16 in FIG. 6 has a penetrating portion 20 through which one lead 2 of the light emitting diode 1 can be inserted. The penetrating portion 20 can be a point-shaped through hole or a band-shaped slit hole. The through-holes, which are through-holes, are opened at predetermined intervals so that a plurality of light-emitting diodes can be ideally connected. The penetrating portion, which is a slit hole, can freely determine the connection position in the vertical direction of the light emitting diode. The front-side elastic holding layer 16 allows the one lead 2 of the light emitting diode 1 to pass through the through portion 20, and passes through the back-side elastic holding layer 17 without contacting the front-side elastic holding layer 16. The penetration 20 preferably insulates the inner surface. The penetration portion 20 can be insulated by passing an insulating cylinder through the inner surface or applying an insulating material to the inner surface. this The front side elastic holding layer 16 is not energized even when the lead 2 inserted into the through portion 20 contacts the inner surface. The other lead 2 of the light emitting diode 1 is inserted into the front side elastic holding layer 16 so that the front side elastic holding layer 16 and the back side elastic holding layer 17 conduct light to the light emitting diode 1 to emit light. I have.

The power supply device 3 shown in FIG. 7 insulates one lead 2 of the light emitting diode 1 without providing a through portion in the surface-side elastic holding layer 16. In the light emitting diode 1, one lead 2 penetrating through the front side elastic holding layer 16 and passing through and connected to the back side elastic holding layer 17 is an insulating lead 2A. The insulating lead 2A insulates the penetrating portion of the front-side elastic holding layer 16 and does not insulate the tip end passed through the back-side elastic holding layer 17. The insulating lead 2A can be provided with an insulating portion on the surface of the lead 2 by passing an insulating tube through the lead 2 or applying an insulating material to the surface. The insulating tube passing through the lead 2 can be, for example, a heat-shrinkable plastic tube. In the light emitting diode 1, an insulating tube is inserted into one of the leads 2, and the insulating tube is heated by a drier or the like to be thermally shrunk, thereby forming an insulated lead having an insulated surface. In the light emitting diode 1, the insulating lead 2A can be inserted into the front side elastic holding layer 16 in an insulated state, and the front end can be connected to the back side elastic holding layer 17. The power supply device 3 connecting the light emitting diodes 1 does not need to provide a through portion in the front side elastic holding layer 16. This is because it is not necessary to insulate the insulating lead 2A at the penetrating part. However, a light emitting diode having one lead as an insulating lead may be inserted into the through portion of the front side elastic holding layer and connected to the back side elastic holding layer.

6 to 10, FIG. 12, FIG. 13, FIG. 15, and FIG. 17 to FIG. 19, the power supply device 3 includes a surface layer 21 on the surface of the front side elastic holding layer 16 and the back side elastic holding layer 17. Laminate them. The surface layer 21 is an insulating layer, and insulates the surfaces of the front side elastic holding layer 16 and the back side elastic holding layer 17. The power supply device 3 having the surface layer 21 can be used safely and conveniently because its surface is insulated. However, the lighting device of the present invention does not necessarily require a surface layer, and the surface layer can be omitted. In the power supply device 3 shown in FIG. 6, the through-hole 20 is opened on one surface layer 21 laminated on the surface of the front-side elastic holding layer 16 in accordance with the position of the through-hole 20 provided on the front-side elastic holding layer 16. are doing.

The surface layer 21 provided on the surface of the surface-side elastic holding layer 16 is Since the lead 2 is inserted, the lead 2 is made of, for example, a synthetic resin foam or a rubber-like elastic body so that the lead 2 can be inserted. The surface layer 21 provided on the surface of the back-side elastic holding layer 17 does not need to be inserted with the lead 2 of the light emitting diode 1, so it should be a synthetic resin plate or a rubber-like elastic plate through which the lead 2 cannot be inserted. Can be. However, both surface layers laminated on the surface of the front surface side elastic holding layer and the back surface side elastic holding layer may be configured to be able to pass through the leads of the light emitting diode. This power supply can connect the light emitting diodes on both sides.

[0091] Further, the surface layer 21 can be made of silicone rubber. Silicon rubber has excellent properties of waterproofness, heat resistance and cold resistance. Therefore, the structure in which the surface layer 21 is made of silicon rubber has a feature that it can be used safely for a long time even when the lighting device is used in a severe environment. The surface layer 21 made of silicone rubber can be provided by applying liquid rubber or silicone rubber to the surface of the front side elastic holding layer 16 or the back side elastic holding layer 17. The method of applying liquid or gell-like silicone rubber is based on synthetic resin foaming that forms the front-side elastic holding layer 16 and the back-side elastic holding layer 17 and has good compatibility with the surface of the rubber-like elastic body. The surface layer 21 can be provided so as not to adhere. In particular, the entire thickness can be reduced by forming the surface layer 21 thinly on the surface of a synthetic resin foam or a rubber-like elastic body. Furthermore, since the surface layer 21 of silicon rubber can be attached while covering the entire surface of the front side elastic holding layer 16 and the back side elastic holding layer 17, there is a feature that excellent waterproofness can be realized. However, the surface layer made of silicone rubber can be provided by bonding sheet-like silicone rubber.

[0092] Further, the surface layer 21 made of silicon rubber has a feature that the lead 2 of the light emitting diode 1 can be smoothly inserted into the surface layer 21 so that the force can be removed. Silicon rubber has a small coefficient of friction with respect to the lead 2 penetrated therethrough, so that the frictional force with the lead 2 penetrated can be reduced. Therefore, the leads 2 of the light emitting diode 1 can be smoothly passed. In particular, the feeling when penetrating the surface layer 21 and passing the lead 2 can be comfortable. Furthermore, since the silicone rubber is soft and has excellent elasticity, it can be stably held so as not to come out of the inserted lead 2. Therefore, while the lead 2 of the light emitting diode 1 is smoothly passed, the lead 2 that is passed through is effectively prevented from coming off, and the light emitting diode 1 is stably held. it can. As described above, the power supply device 3 that holds the inserted lead 2 of the light emitting diode 1 by the surface layer 21 has a feature that an excellent holding force can be realized while making the whole thin.

[0093] The surface layer made of silicone rubber can be provided on both the surface of the front side elastic holding layer and the back side elastic holding layer, or can be provided only on the surface of the front side elastic holding layer. Further, the surface layer of the silicon rubber may be provided on both surfaces of the front side elastic holding layer and the back side elastic holding layer. In this power supply device, the insulating layer can be formed by the surface layers provided on the opposing surfaces of the front side elastic holding layer and the back side elastic holding layer. The power supply device 3 shown in FIG. 21 has a surface layer 21 on both surfaces of a front side elastic holding layer 16 and a back side elastic holding layer 17 and an insulating material 31 interposed between the surface layers 21 facing each other. Then, the insulating layer 18 is formed. As the insulating material 31, for example, paper, a plastic film, a nonwoven fabric, or the like can be used. The insulating layer 18 has a three-layer structure including a surface layer 21 and an insulating material 31, and has a feature that the overall thickness can be reduced while achieving excellent insulating properties. However, this insulating material can be omitted, and the surface layers of the front-side elastic holding layer and the back-side elastic holding layer are provided only on one of the opposing surfaces.

Further, since the power supply device 3 of FIG. 21 forms the insulating layer 18 with silicon rubber, the power supply device 3 can hold firmly while smoothly inserting the lead 2 penetrating the insulating layer 18. That is, the power supply device 3 having this structure not only elastically holds the lead 2 of the light-emitting diode 1 to be inserted by the front-side elastic holding layer 16 and the back-side elastic holding layer 17, but also Since the surface layer 21 on both sides of the holding layer 16 and the surface layer 21 on the inner surface side of the back side elastic holding layer 17 are also held, they can be firmly held so as not to come off. In particular, it is possible to effectively prevent the light emitting diode 1 from coming off while making the entire power supply device 3 thin.

[0095] The front side elastic holding layer 16 and the back side elastic holding layer 17 are connected to a power supply. This lighting device is lit by connecting one lead 2 of the light emitting diode 1 to the front side elastic holding layer 16 and connecting the other lead 2 to the back side elastic holding layer 17. The light-emitting diode 1 has a lead 2 passing through the back side elastic holding layer 17 so that one side can pass through the front side elastic holding layer 16 and the other can pass through the back side elastic holding layer 17. Make it longer than lead 2 that goes through. In other words, the lead 2 of the light emitting diode 1 is passed through the power supply device 3 until the one lead 2 is connected to the front side elastic holding layer 16, and the other lead 2 is connected to the back side. The length of the pair of leads 2 is specified so as to be inserted into the elastic holding layer 17. The light emitting diode 1 is in a state where the other lead 2 is inserted into and connected to the back side elastic holding layer 17, and one lead 2 is connected to the front side elastic holding layer 16 which cannot reach the back side elastic holding layer 17. Inserted and connected.

As shown in FIG. 6 and FIG. 21, the power supply device 3 having the surface-side elastic holding layer 16 and the back-side elastic holding layer 17 stacked thereon allows the light-emitting diode 1 to be positioned at any position in the vertical and horizontal directions. Since the LEDs can be arranged and lit, the LEDs 1 can be fixed and lit at the optimal position for the application.
