An example of a substrate for mounting an LED is described in Patent Document 1 below. The substrate has a strip shape for a positive electrode and a negative electrode made of a conductive metal, and a resin portion that is injection-molded and integrally holds both the strip plates in an insulated state. A plurality of light emitting diodes (LEDs) are mounted on one surface of the belt-like substrate so as to be separated from each other in the extending direction, thereby forming LED illumination.

JP 2011-146187 A

  The above LED illumination can be wound and wound in a reel-wound shape by winding a belt-like substrate, so that it can be pulled out from the reel and cut into a free length. However, if a very long LED lighting is energized with a single DC power source (for example, a battery), a large battery is required, and the entire long LED lighting will not light up unless the battery is activated due to a failure or the like. become. Therefore, a configuration in which a plurality of strip-shaped LED lights are connected and a battery and a switch are provided for each LED light has been studied. In this way, by disposing the batteries in a distributed manner, each battery can be reduced in size and reduced in cost and can be reduced in size, and even if one of the batteries does not operate, the other batteries can operate and the LED illumination Can be lit.

  However, as described above, when a battery and a switch are provided for each of the plurality of LED lights, it is necessary to control the switch of each LED light, and wiring for this purpose is required. If such a wiring is arranged along the substrate, a space for providing the wiring is required and the aesthetic appearance is impaired. Moreover, since a separate process for providing wiring is required, it takes time and effort.

  The technical problem to be solved by the present invention is that, when a plurality of LED lights are connected and used, the wiring for controlling each LED light is compact, does not impair the aesthetics, and requires a separate process. There is to provide without.

  The striped substrate for LED lighting according to the present invention made to solve the above problems is formed by injection molding in which both strips for positive and negative electrodes made of conductive metal are inserted, A resin part that integrally holds the band plate in an insulated state, a plurality of LED mounting parts that are arranged apart from each other in the direction in which the band plate extends, and for connecting the LEDs to both the band plates so as to be energized; It is inserted into the resin part together with the plate, and is provided with both strips and an insulated bypass line. The strip substrate for LED lighting can be manufactured by inserting both strip plates and bypass wires and injection molding the resin portion.

  If several LED is attached to the LED attachment part of said strip | belt-shaped board | substrate, it can be used as LED illumination. Further, if a plurality of LED illuminations are connected and a control unit for controlling a plurality of LED illuminations is provided via a bypass line and a positive electrode strip or a negative electrode strip, the LED illumination device can be used.

  As described above, by inserting a bypass line for controlling each LED illumination into the resin part of the belt-like substrate, the bypass line is provided inside the resin part, so that the bypass wire is provided around the belt-like substrate. Space is not required and the aesthetic appearance is not impaired because the bypass line is not exposed. Further, since the bypass line can be inserted into the resin portion together with the positive and negative electrode strips, a separate process for providing the bypass line is not required.

  Specifically, for example, for each LED illumination, a DC power source capable of supplying power to the LED via both strips, and a switch disposed between the DC power source and the positive strip or negative strip And the control unit can be configured to be connected to a plurality of LED lighting switches via a bypass line and a positive electrode strip or a negative electrode strip. In this case, a signal from the control unit can be transmitted to each switch via the bypass line, and the switch can be turned on / off. In this LED lighting device, if the strips for the positive electrodes of the plurality of LED illuminations and the strips for the negative electrodes are connected so that they can be energized, even if one of the DC power supplies does not operate, All LED lights can be turned on by the power source.

  If a detection unit that detects the occurrence of disturbance is connected to the control unit, the control unit that receives the detection signal of the detection unit switches on the switch to automatically turn on the LED and use it as emergency lighting. It becomes possible. As the detection unit, for example, any one of a vibration sensor, a temperature sensor, and a human sensor can be used. If it is a vibration sensor, an earthquake occurs, a temperature sensor detects a fire, and a human sensor detects the approach of a pedestrian, and recognizes that an emergency has been reached.

  As described above, according to the present invention, each LED illumination is controlled even when a plurality of LED illuminations are connected and used by inserting a bypass wire into the resin portion together with the positive and negative strips. The wiring to be performed can be provided in a compact manner without impairing the aesthetics and without requiring a separate process.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, an LED lighting device 1 according to an embodiment of the present invention includes a plurality of LED illuminations 1 a including a strip-shaped substrate 2 and a plurality of LEDs 3 that are spaced apart in the extending direction of the strip-shaped substrate 2. And a plurality of power supply units 4 connected to each LED illumination 1a and supplying power to the LEDs 3. In the present embodiment, a plurality of LED lights 1 a are connected via a connector 11, and the power supply unit 4 is built in the connector 11.

  As shown in FIGS. 2 to 4, the belt-like substrate 2 has two belt plates 21 and 22 and a bypass belt plate 30 as a bypass line arranged in parallel, and these are integrally held by a resin portion 24. It has a strip shape. The three strips 21, 22, and 30 are all conductive metals (eg, copper plate, aluminum plate, stainless steel plate, etc.) having a thickness of about 0.01 mm to 3 mm (for example, 0.1 mm) and having high flexibility. It is formed. In the illustrated example, three strip plates 21, 22, 30 are arranged on the same plane. Terminals 23 for connection to the power supply unit 4 are formed at the ends of the strips 21, 22, 30. In the illustrated example, terminals 23 are formed at both ends of the strips 21, 22, 30. A conductive metal film can be formed on the surfaces of the strips 21, 22, and 30 by tin plating or the like, if necessary.

  Since the bypass strip 30 is provided to transmit a signal from the switch controller 43 described later, the energization amount may be smaller than that of the positive and negative strips 21 and 22. Accordingly, the bypass strip 30 may have a smaller cross-sectional area than the positive and negative strips 21 and 22. For example, in the case where strips having the same thickness are used, the bypass strip 30 may have a smaller width than the strips 21 and 22 for the positive electrode and the negative electrode. The bypass line is not necessarily formed of a strip, and may be formed of, for example, a conducting wire having a circular cross section (for example, copper wire).

  The resin part 24 covers both sides of the strips 21, 22, and 30 excluding the terminal 23 over the entire longitudinal direction, and satisfies the gap between the strips 21 and 22 and the gap between the strips 22 and 30. . As will be described later, the resin portion 24 is formed by inserting the band plates 21, 22, and 30 and performing injection molding. The resin material can be arbitrarily selected according to the use conditions of the lighting device 1, and for example, LCP, PPS, POM, PEEK, or the like can be used.

  A plurality of window portions 26 as LED mounting portions are formed in the resin portion 24 at an appropriate pitch (equal pitch or unequal pitch) along the direction in which the strips 21 and 22 extend. As shown in FIG. 4, the window portion 26 is one surface of the belt-like substrate 2 between the two strips 21 and 22 (the surface on the LED 3 mounting side; hereinafter referred to as “surface”) and the other. (Referred to as “rear surface” hereinafter). The inner edge portions of the two band plates 21 and 22 protrude into the window portion 26, and the inner surface of the window portion 26 can accommodate the LEDs 3 on the surface side of the inner edge portions of the protruding band plates 21 and 22. It has become. The inner edge portions of the band plates 21 and 22 protruding into the window portion 26 function as the terminals 27, and it is possible to supply power to the LEDs 3 by bringing them into contact with the terminals 32 (described later) of the LEDs 3. A plurality of mounting holes 28 penetrating the front and back surfaces are formed at appropriate intervals in the region between the two strips 21 and 22 in the resin portion 24 (see FIG. 2).

  On the surface of the resin part 24, the periphery of the window part 26 and the mounting hole 28 is raised more than the other parts (see FIGS. 3 and 4). Except for the raised portions 26a and 28a, the resin portion 24 has a uniform thickness T1. As indicated by an arrow W in FIG. 3, the thickness of each part of the resin part 24 is made as thin as possible in order to allow the belt-like substrate 2 to be bent with its surface side convex. Specifically, the thickness T1 of the resin portion 24 is about 0.3 mm to 1.5 mm (for example, 1 mm), and the thickness Tmax of the raised portions 26a and 28a having the maximum thickness is about 1.5 mm to 4 mm (for example, 2 mm). The back surface of the resin part 24 is a flat surface without unevenness.

  As the LED 3, a so-called surface mount type (or chip type) as shown in FIG. 5 is used. The configuration and form of the LED 3 are arbitrary, and FIG. 5 illustrates the LED 3 that is a multichip having a plurality of (three in the illustrated example) light emitting elements 31 and is packaged in a thin rectangular parallelepiped shape. In addition to the multichip, a single chip can also be used. The LED 3 has a pair or a plurality of pairs of terminals 32 corresponding to the number of the light emitting elements 31. The terminal 32 has an L-shaped cross section, and protrudes from the vicinity of the central portion in the height direction of the side surface of the LED 3 to extend along the side surface and the bottom surface. The emission color of the LED 3 is arbitrary, and for example, white can be used. Note that the LED 3 is not limited to the surface mount type but may be a so-called bullet type.

  As shown in FIG. 3, the LEDs 3 are attached to the belt-like substrate 2 by being fitted one by one into the window portion 26 of the resin portion 24. At this time, by bringing the terminal 32 of the LED 3 into contact with the terminal 27 of the band plates 21 and 22 protruding into the window portion 26, electrical conductivity between the band plates 21 and 22 and the terminal 32 of the LED 3 is ensured. . The terminals 27 and 32 of the belt plates 21 and 22 are processed into a shape that can be elastically deformed by pressing or the like, and further provided with a retaining structure that engages with the LED 3 on the side of the belt-shaped substrate 2, so that the terminals 27 and 32 are pressed against each other. It is possible to stabilize the energized state. In the retaining structure, for example, the inner surface of the window portion 26 of the resin portion 24 is provided with an allowance for the exterior surface of the LED 3 or the upper surfaces 32a of the terminals 32 of the LED 3 by pressing the band plates 21 and 22 (FIGS. It is possible to configure by forming an engaging portion that engages with (see). After the LED 3 is mounted, it is preferable that the upper surface level of the LED 3 is the same level as the upper surface of the raised portion 26a of the resin portion 24 (see FIG. 4) or lower than the upper surface of the raised portion 26a. Thereby, even if it is a case where the LED lighting apparatus 1 is attached to the place where a person steps on, since LED3 is not stepped on directly, the load added to LED3 can be reduced and damage can be prevented. Note that the method of mounting the LED 3 on the belt-like substrate 2 is not limited to the above. For example, the terminal 32 of the LED 3 and the belt plates 21 and 22 of the belt-like substrate 2 may be fixed by soldering.

  In FIG. 2, the LEDs 3 are not fitted into some of the window portions 26, but this is for clarifying the configuration of the belt-like substrate 2 by clearly showing the terminals 27 on the drawing. LED 3 is fitted in (see FIG. 1). Depending on the required illuminance, it is not necessary to fit the LEDs 3 in all the window portions 26, but the LED 3 may be attached only to some of the window portions 26, and the attachment of the LEDs to other window portions 26 may be omitted. .

  The connector 11 mechanically and electrically connects the plurality of LED lights 1a. Each of the opposing surfaces of the connector 11 is provided with positive and negative female terminals 12 that are compatible with the three male terminals 23 of the belt-like substrate 2 (see FIG. 1). By inserting the male terminals 23 of the two adjacent boards 2 into the female terminals 12 of the connector 11, the strips 21 on the positive side, the strips 22 on the negative side, and the strips 30 for bypassing each other. Can be connected to be energized. In this case, as shown in FIG. 2, it is desirable to form terminals 23 at both ends of the belt-like substrate 2.

  Thus, after connecting the plurality of strip-like substrates 2 via the connector 11, a mechanical retaining structure is provided between the connector 11 and each substrate 2 so that the strip-like substrate 2 does not fall off the connector 11. preferable.

  Further, when the strip substrate 2 is connected using the connector 11 as described above, the battery 41, the switch 42, the switch control unit 43, and the detection unit 44 constituting the power supply unit 4 are connected as shown in FIG. The connector 11 is preferably held. The connector 11 can be easily manufactured by performing predetermined wiring between the components of the power supply unit 4, inserting them into the mold together with the female terminals 12, and performing injection molding with resin.

  FIG. 6 shows a circuit diagram of the illumination device 1 according to the present invention. As shown, the circuit includes a power supply unit 4 and a main body unit 5. The power supply unit 4 includes a battery 41 as a DC power supply, a switch 42, a switch control unit 43 that controls opening and closing of the switch 42, and a detection unit 44 connected to the input side of the switch control unit 43. As the battery 41, either a primary battery or a secondary battery can be used. When a secondary battery is used, the battery 41 is connected to a commercial power supply or a solar battery so that it can be charged. The detection unit 44 detects the presence or absence of disturbance, and a sensor can be used as a representative example. The type of sensor can be arbitrarily selected according to the type of disturbance to be detected. For example, any one of a vibration sensor, a temperature sensor, and a human sensor can be used. Note that the DC power supply is not limited to a battery, and includes, for example, an AC current converted into a DC current via a converter and supplied.

  The main body 5 includes two strips 21 and 22 and a bypass strip 30 and an LED 3 connected in parallel between the strips 21 and 22. The positive side of the battery 41 is connected to the terminal 23 of one strip 21, and the negative side of the battery 41 is connected to the terminal 23 of the other strip 22 via the switch 42. The switch 42 can also be disposed on the positive electrode side of the battery 41. From the above configuration, one of the strips 21 serves as the positive-side wiring 51 of the main body 5, the other strip 22 serves as the negative-side wiring 52 of the main body 5, and the bypass strip 30 serves as the bypass wiring 53. By connecting the LEDs 3 in parallel, the LEDs 3 attached to the window portions 26 can be turned on even when the LED 3 is not attached to some of the window portions 26 as described above. In addition, LED3 can also be connected in series by changing the shape of the strips 21 and 22, changing a circuit, and mounting LED3 to all the window parts 26. FIG. The power supply unit 4 is provided with a current limiting resistor (not shown), for example, between the battery 41 and the strip 21 on the positive side, between the battery 41 and the switch 42, or between the switch 42 and the strip on the negative side. 22 is arranged.

  The lighting device 1 described above can be manufactured by the following procedure.

  First, as shown in FIG. 7, three strips 21, 22, 30 guided in parallel at intervals are intermittently fed into the injection molding machine 7 at a predetermined pitch, and the resin is injected into the mold. Resin portion 24 is formed. Thereby, the strip | belt-shaped board | substrate 2 which hold | maintained the three strips 21, 22, and 30 integrally by the resin part 24 and insulated between the three strips 21, 22, and 30 by the resin part 24 is obtained. The strips 21 and 22 can be punched or plastically deformed by press working, and in this case, these processings are performed before feeding into the injection molding machine 7 or in the injection molding machine 7.

  Next, the LED 3 is mounted on the window portion 26 of the substrate 2 carried out from the injection molding machine 7. The board | substrate 2 with which LED3 mounting | wearing was mounted | wound is wound up one by one in order, and is transferred to a post-process. In the post-processing step, the substrate 2 is pulled out of the roll and cut to a predetermined size, and one end of the resin portion 24 is removed to expose the terminal 23, thereby forming the LED illumination 1a (see FIG. 2). In addition, the formation method of the terminal 23 is not limited to this. For example, when the use length is determined in advance, the resin portion 24 is injection-molded with the end portions of the strips 21, 22, and 30 exposed, This exposed portion may be the terminal 23. Thereafter, the plurality of LED illuminations 1a are connected via the connector 11, and the power supply unit 4 is connected to the terminal 23 of the substrate 2 of each LED illumination 1a, whereby the illumination device 1 is completed. Note that the end user can also connect the power supply unit 4 to the substrate 2 and attach / remove the LEDs 3 to / from the belt-like substrate 2.

  In FIG. 7, the configuration in which the three strips 21, 22, 30 in a separated state are supplied to the injection molding machine 7 is illustrated, but one strip is fed forward and cut immediately before the injection molding machine 7. In addition, after dividing the strip into three, these can be supplied to the injection molding machine 7.

  When the lighting device 1 of the present invention is attached to the structure 8, for example, as shown in FIG. 8, a groove 81 is formed on the surface of the structure 8, and the lighting device 1 is accommodated in the groove 81. Next, a screw member such as a tapping screw is screwed into the attachment hole 28, and the lighting device 1 is attached to the bottom surface 82 (surface to be attached) of the groove 81. After the attachment, the entire flat back surface (attachment surface 29) of the resin portion 24 is in close contact with the bottom surface 82 of the groove 81. Then, the installation of the illuminating device 1 is completed by installing the power supply part 4 connected to the terminal 23 in an appropriate place. As shown by a two-dot chain line in the figure, if the lighting device 1 is attached to the groove 81 and then the cover 83 made of a transparent resin or the like is attached to the groove 81 to seal the lighting device 1, the aesthetic appearance is improved. In addition, it is possible to prevent the strips 21 and 22 from being short-circuited by water droplets or foreign matters.

  As the structure 8 to which the lighting device 1 is attached, a corridor in a house (a building or a residence), a stepping surface, a kicking surface, a handrail, a wall surface, or the like of a staircase can be considered. In addition, the lighting device 1 can be mounted on the wall surface of an outdoor structure such as a curb or a guardrail. The lighting device 1 can be attached by screws as described above, or by attaching the attachment surface 29 of the resin portion 24 to the attachment surface with a double-sided tape or the like. If there is no particular problem, the lighting device 1 may be directly attached to the surface (attached surface) of the structure without forming the groove 81.

  In this illumination device 1, as shown in FIG. 6, all the switches 42 are normally held in an open state (switch-off) by the switch control unit 43. In this state, no current flows through the power supply unit 4 and the main body unit 5, and each LED 3 is in a light-off state. On the other hand, when the detection unit 44 detects the transition to an emergency due to the occurrence of a disturbance, the signal is input to the switch control unit 43, and the switch control unit 43 receives the signal from the bypass wiring 53 and the negative electrode strip 22 (or alternatively). A signal is transmitted to the switch 42 of each power supply unit 4 through a circuit through the positive side strip 21), and all the switches 42 are closed (switch-on). Thereby, the current from the battery 41 flows through the power supply unit 4 and the main body unit 5, and each LED 3 is lit. Therefore, it is possible to ensure illumination even when a power failure occurs. If a vibration sensor is used for the detection unit 44, it can be used as the lighting device 1 when an earthquake occurs, and if a temperature sensor is used, it can be used as the lighting device 1 when a fire occurs. Moreover, if a human sensor is used for the detection part 44, it can be used as the illuminating device 1 which lights only when a pedestrian approaches.

  As described above, by connecting the plurality of strip-shaped LED lights 1 a with the connector 11, the length of the strip-shaped substrate 2 can be extended, and the long lighting device 1 can be provided. In addition, by distributing the power supply units 4 (batteries 41), each power supply unit 4 can be made smaller, thereby reducing costs and making it compact, and even if any power supply unit 4 does not operate, Since the power supply unit 4 can be operated and the LED illumination 1a can be turned on, safety is ensured even when used as an emergency illumination.

  As shown in FIG. 6, when two or more connectors 11 are used to connect three or more belt-like substrates 2, one switch control unit 43 and one detection unit 44 are sufficient for the entire lighting device 1. Therefore, when the switch control unit 43 and the detection unit 44 are provided in any one of the connectors 11, these can be omitted in the other connectors 11. In this case, the other connector 11 is provided with a battery 41 and a switch 42. A control signal is transmitted from the switch control unit 43 to each switch 42 via the bypass wiring 53 and the negative strip 22 (or the positive strip 21).

  Moreover, according to said illuminating device 1, since the strip | belt-shaped board | substrate 2 itself is thin, the thickness of the illuminating device 1 whole can be made thin (about several mm). Therefore, even when covered with the cover 83, the thickness can be reduced, and even when attached to the structure 8, the aesthetic appearance of the structure 8 is not impaired, and the original function of the installation surface of the structure 8 (for example, the passage) As a function). In particular, since the bypass line (bypass band plate 30) is inserted into the resin portion 24 of the belt-like substrate 2, a space for providing the bypass line is unnecessary and the bypass line is not exposed, so that the structure 8 is beautiful. There is no loss of functionality. Existing emergency lights are generally large, and their mounting positions are limited to the corners of the ceiling and hallway so as not to obstruct walking. It can be installed in places where existing products cannot be installed. Therefore, the degree of freedom of the mounting position is improved, and a new usage pattern of the lighting device 1 can be realized.

  In addition, as described above, the strips 21 and 22 for the positive electrode and the negative electrode and the bypass wire are inserted and the resin portion 24 is injection-molded, so that a separate process for providing the bypass wire on the belt-like substrate 2 is not necessary. It becomes. In particular, by using the strip 30 as the bypass line, the strips 21, 22, and 30 can be formed from a single strip-shaped metal plate.

  In addition, since the belt plate 21 on the positive electrode side and the belt plate 22 on the negative electrode side are covered with the resin portion 24 and are in an insulating state, it is possible to reliably prevent a short circuit between the belt plates 21 and 22 due to water and foreign matter. Therefore, it is possible to install the LED 3 on the substrate 8 as it is simply by mounting the LED 3 on the substrate 2. Further, if the battery 41 and the switch 42, or the battery 41, the switch 42, the switch control unit 43, and the detection unit 44 are wired to complete the power supply unit 4 (connector 11) in advance, the terminal 23 of the belt-like substrate 2 is connected. The lighting device 1 can be operated simply by connecting to the terminal 12 of the connector 11, and complicated wiring work is not required. Therefore, the attachment work of the illuminating device 1 can be simplified, and it can also be attached to the structure by the end user. Even if a short circuit occurs between the strips 21, 22, 30, etc., the voltage applied between the terminals 32 of the LED 3 is a low voltage of about several volts, so that no particular problem arises in terms of safety.

  Further, each of the positive side and negative side strips 21, 22, and 30 covers the one side surface (front surface) and the other side surface (back surface) with the resin portion 24, and covers the other side surface. If the attachment surface 29 for attaching to the structural body 8 is provided in the resin portion 24, a short circuit between the strip plates 21, 22, and 30 via the structural body 8 is possible even when the strip-like substrate 2 is attached to the structural body 8. Can be prevented.

  If the LEDs 3 are connected in parallel as in the present embodiment, disconnection does not occur even if the substrate 2 is cut at an appropriate position in the length direction after the substrate 2 is manufactured, and each LED can be turned on. Therefore, it is also possible to adopt a sales mode in which the substrate 2 is sold and sold at a retail store.

  Hereinafter, other embodiments of the present invention will be described.

  A plurality of bypass lines may be provided on the belt-like substrate 2. For example, as shown in FIG. 9, two bypass belt plates 30 may be provided. In the illustrated example, one bypass strip 30 is provided on each side of the positive and negative strips 21 and 22, and as a whole has a line-symmetric shape with respect to the center in the width direction. By providing a plurality of bypass strips 30 in this way, variations in the control of the LED illumination 1a are expanded. For example, as shown in FIG. 10, if two bypass wirings 53 extending from the switch control unit 43 are alternately connected to the switches 42 of the plurality of power supply units 4, they are connected to one bypass wiring 53 (A). The power supply unit 4 (A) and the power supply unit 4 (B) connected to the other bypass wiring 53 (B) can be controlled separately. For example, a group of main body parts 5 (that is, LED lighting 1a) (A) connected to one bypass wiring 53 (A) and a group of main body parts 5 (B) connected to the other bypass wiring 53 (B). And can be blinked alternately. In this case, the plurality of LED illuminations 1a are mechanically coupled via the connector 11, and the bypass strips 30 of the LED illuminations 1a are connected to be energized, but the positive electrode strips of the LED illuminations 1a. 21 and the strips 22 for negative electrodes are not connected.

  Moreover, it is not always necessary to provide the LED lighting 1a and the power supply unit 4 one-on-one. For example, a unit may be configured by connecting a plurality of LED lights 1a so that energization is possible, and a power supply unit may be provided for each unit.

  The embodiment shown in FIG. 11 is a lighting device 1 with an enhanced short circuit prevention function, and is particularly suitable for outdoor use. In the embodiment shown in FIGS. 1 to 8, the outer edge portions of the strip plates 21 and 30 and the back surface located in the window portion 26 of the strip plates 21 and 22 are covered with the resin portion 24 as apparent from FIG. 4 and the like. It is exposed. On the other hand, in the embodiment shown in FIG. 11, the outer edge portions of the band plates 21 and 30 are covered with the resin portion 24, and the opening on the back side of the window portion 26 is also closed with the resin portion 24. The exposed portions of the plates 21, 22, 30 are eliminated. Further, the gap between the periphery of the LED 3 and the window portion 26 is covered with the sealing material 10. As the sealant, it is preferable to use one having excellent adhesion to a resin, metal, etc. For example, an acrylic adhesive, an epoxy adhesive, a UV curable adhesive, or the like can be used. With the above configuration, it is possible to more reliably prevent a short circuit between the strips 21, 22, and 30 due to rainwater and foreign matter. In addition, the structure which coat | covers the outer edge part of the strips 21 and 30 with the resin part 24, the structure which covers the opening part of the back surface side in the window part 26 of the strips 21 and 30 with the resin part 24, and the circumference | surroundings of LED3 Of the configurations in which the gap between the window portions 26 is covered with the sealing material 10, any one or two configurations can be applied.

  The configuration, usage mode, and function of the lighting device 1 according to the present invention described above are merely examples. For example, in the above description, the case where the belt-like substrate 2 is attached to the planar attachment surface has been described, but the shape of the attachment surface is arbitrary, and the belt-like substrate 2 can be attached to the curved attachment surface.
