Description

  The present invention relates to a lighting fixture in which a plurality of LED modules are connected.

  Conventionally, as this luminaire, there has been a plurality of LED lamps connected in a tape shape, but since the lead wires connecting the LED lamps are not loose, LED lamps are installed one by one at the installation site. It was necessary to fix with one screw etc., and the work took time. Thus, a lighting fixture was invented in which an LED lamp was previously attached to a holding member having holding power. For example, it has been described in Patent Document 1 and Patent Document 2. FIG. 8 shows a conventional luminaire described in Patent Document 1, and FIG. 9 shows a light-emitting unit of the conventional luminaire described in Patent Document 2.

  In FIG. 8, the flexible tube 62 is a flexible rod-like body, the light emitting device 63 is provided on the surface of the flexible tube 62, and the lead wire 64 electrically connects the light emitting devices 63 to each other. This is for supplying electric power to the light emitting device 63 located at the end of the flexible tube 62. Thereby, the illuminating device 61 can maintain the state which irradiated the light suitably emitted from the light-emitting device 3 to the target object, bending the flexible tube 62 so that it may match shapes, such as a shelf.

  Further, the light emitting unit 7 of the LED lighting apparatus shown in FIG. 9 is such that individual LEDs 71 are independently mounted on a long belt-like flexible board 72, 73 with a space therebetween, and these LED lights are flexible. It was attached to a flexible attachment frame to form an LED lighting device.

JP 2014-41752 A JP2013-118169A

  However, in the configuration described in Patent Document 1 of the above-described conventional example, the flexible tube 62 is a wave-like shape in which a plurality of ring bodies are connected, a braided stainless steel wire, or a flexible tube. Since a certain material is made into a rod shape, the degree of freedom in the extending direction is small even if it can be bent in all directions intersecting the extending direction, so it is necessary to slightly adjust the longitudinal direction at the installation site of the luminaire. When it occurred, there was a problem that the flexible tube had to be cut or added.

  Further, even in the configuration described in Patent Document 2 of the above-described conventional example, since the LED mounting portion 74 is fixed to the flexible substrates 72 and 73 on which the power supply pattern having no stretchability is formed, it cannot be extended in the longitudinal direction. There was a problem similar to that of Patent Document 1 at the installation site of the LED lighting apparatus.

  The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide an LED lighting apparatus that can freely correspond to a mounting shape and a size thereof in a lighting construction site.

  An LED lighting apparatus according to the present invention that solves the above-described conventional problems is an LED module in which an LED element is attached to a substrate and connected by a lead wire for energization at predetermined intervals. It is attached to a sheet of linear fixing members, and a joint portion in which a plurality of slits are provided in the width direction is formed between the LED modules of the fixing members.

  As a result, the joint portion is flexible and extensible, and the joint portion can be bent, twisted, and extended, so that it can be attached to a surface having a complicated shape.

  Further, the fixing member at the portion where the plurality of LED modules are attached is removed, and the LED module is coupled to the extension portion of the joint portion.

  Thereby, the LED lighting apparatus can be reduced in weight.

  Moreover, the LED lighting fixture which concerns on this invention consists of the meandering path | route whose joint part is 1 or 2 or more.

  This makes it possible to widen the LED module mounting interval by extending the meandering path.

  The fixing member of the LED lighting apparatus according to the present invention is a laminated composite plate of metal and resin, and the metal is any one of aluminum, titanium, stainless steel, aluminum / zinc alloy, steel, and copper.

  As a result, the weight of the fixing member is reduced, the workability is improved, and the heat dissipating capability of the metal thin plate is also increased. Therefore, the burden of mounting work at the site is reduced, the processing work is easy, and the heat dissipation of the LED module Is possible.

  In the LED lighting apparatus according to the present invention, the length of the lead wire for electrically connecting the LED modules is longer than the distance between adjacent LED modules and shorter than the total length of the meandering path of the joint portion.

  Thereby, even if the meandering path of the joint portion is extended, there is no restriction due to the length of the lead wire, and the LED module mounting interval can be extended to the maximum.

  According to the present invention, it is possible to easily and efficiently attach the LED lighting apparatus to a complicatedly shaped surface, and it is possible to freely cope with the mounting shape and size at the construction site.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is an external view of an LED lighting apparatus according to Embodiment 1 of the present invention.

  In FIG. 1, an LED module 11 is obtained by covering a LED element in which an LED element is resin-sealed with a wide-angle lens 111 and providing electrodes 112 a, 112 b, 113 a, and 113 b for connecting lead wires 13. The opposite surface has a flat shape. The electrodes 112a, 112b, 113a, 113b have a structure that can be easily attached and detached without soldering the lead wires 13. The LED module 11 has polarity, the electrodes 112a and 113a are positive electrodes, the electrodes 112b and 113b are negative electrodes, the electrodes 112a and 112b are input sides, and the electrodes 113a and 113b are output sides. The attachment hole 114 is a hole for attaching the LED module to the construction surface with screws or the like. In addition, the weight of the LED module of this Embodiment is about 13 grams.

  The aluminum composite plate 12 has a three-layer structure in which a resin core material such as polyethylene having a thickness of 2.7 millimeters is sandwiched from both sides by an aluminum plate having a thickness of 0.15 millimeters. The width is about 35 millimeters and the length is about 90 millimeters. It is a centimeter linear plate material, and includes an attachment portion 122 to which the LED module 11 is attached, and a joint portion 121 that connects the LED modules arranged at equal intervals. The mounting portion 122 has a hole for passing a screw from the mounting hole 114 of the LED module 11. The LED lighting fixture 1 according to the present embodiment uses ten LED modules 11 arranged side by side. As described above, since the aluminum composite plate 12 has a structure in which both sides of the resin core are sandwiched between the aluminum plates, the aluminum composite plate 12 is light in weight and high in rigidity.

  A flat surface that is not on the wide-angle lens 111 side of the LED module 11 is attached to the attachment portion 122 of the aluminum composite plate 12 with an adhesive, a double-sided tape, or a screw. In order to enhance the effect of radiating heat generated in the LED module with the aluminum composite plate, it is preferable to attach the adhesive with an adhesive having high thermal conductivity.

  As shown in FIG. 1, the joint portion 121 has one meandering path 15 formed by three slits 16 in the width direction. By providing the meandering path 15 in this way, bending and twisting at the joint portion 121 are performed. Enables torsion and extension.

  FIG. 2 is a diagram illustrating a state in which the joint portion 121 of the LED lighting apparatus of the present embodiment is deformed.

  FIG. 2A shows the LED lighting apparatus 1 along a curved shape by opening a bent portion (hereinafter referred to as a joint) 121a of the meandering path 15 of the joint 121, and FIG. 2B shows the joint 121b. The direction of opening is opposite to (a). (C) is an extension of the length of the joint portion 121 by opening all the joints 121a and 121b, whereby the mounting pitch of the LED module 11 can be changed. (D) shows the joints 121a and 121b twisted in the width direction.

  As shown in FIG. 2, the joint portion serves as a fulcrum when the joint portion 121 is bent or twisted, so that all bending and twisting are performed at the joint portion. Therefore, FIG. 2A has two joints 121a serving as fulcrums, whereas FIG. 2B has only one joint 121b serving as a fulcrum, so that the curvature at the curved portion is as shown in FIG. ) Is smaller than in the case of.

  Moreover, although all the joints are opened in FIG. 2 (c), it is not preferable to open the joints until they are completely straight because the resin core material of the aluminum composite plate 12 is damaged. Furthermore, by extending the joint portion 121, the rigidity of the joint portion 121 is reduced and bending occurs. Therefore, in the aluminum composite plate used in the present embodiment, the resin core material of the joints 121a and 121b is damaged. It is preferable to be up to 30 degrees in the horizontal direction that can be opened without any trouble.

  Moreover, in this Embodiment, the slit width of the joint part 121 is 4 millimeters, and the width of the meandering path 15 is also 4 millimeters. That is, the width of the meandering path 15 is substantially the same as the thickness of 3 mm of the aluminum composite plate. Thereby, when the joint part 121 is twisted, the stress acts almost evenly, so that the meandering path 15 is not easily damaged.

  It is possible to increase the width of the meandering path 15 to 6 millimeters, which is twice the thickness of the aluminum composite plate, to increase the rigidity. However, increasing the thickness further affects the tensile strength of the resin core material. This makes bending and twisting at the joint difficult, and stressed parts concentrate and are susceptible to damage. Further, if the width of the meandering path 15 is made thinner than the thickness of 3 mm of the aluminum composite plate, the rigidity at the joint portion 121 is weakened and bending is increased, which is not preferable. Therefore, when the joint portion is formed by one meandering path 15, the width of the meandering path 15 is preferably in the range of the same as the aluminum composite plate thickness of 3 millimeters up to twice.

  The rigidity of the joint portion 121 varies depending on the relationship between the aluminum plate thickness of the aluminum composite plate and the thickness of the resin core material, but when the aluminum composite plate thickness is approximately 17% or more of the resin core material, the width of the meandering path 15 Even if the thickness is substantially the same as the aluminum composite plate thickness, the rigidity of the joint portion 121 can be sufficiently maintained.

  Further, the twist angle when twisting the meandering path 15 is also within 30 degrees in order to prevent damage to the resin core material of the joints 121a and 121b in the aluminum composite plate used in the present embodiment. It is preferable to do.

  In FIG. 1, a lead wire 13 is for electrically connecting the electrodes 112a and 112b of the LED module 11 and the electrodes 113a and 113b of the adjacent LED module 11, respectively. The electrodes are connected in series with a lead wire 13. The plus electrode 113a and the minus electrode 113b of the terminal LED module 11b are short-circuited.

  In addition, the length of the lead wire is not the distance to the electrode of the adjacent LED module 11 before the joint portion 121 extends, but the length of the meandering path 15 in consideration of the distance that the joint portion 121 extends. preferable. Thereby, even if it is time when the joint part 121 carries out what kind of deformation | transformation, it will not receive a restriction | limiting by this lead wire.

  The connector 14 attached to the lead wire 13 of the LED module 11a at the start end is connected to a lead wire for supplying a direct current to the LED lighting device 1 from a constant current power source (not shown).

  About the LED lighting fixture 1 comprised as mentioned above, the operation effect by using the LED lighting fixture concerning the handling in the construction site of an LED lighting fixture and this invention is demonstrated below.

  FIG. 4 is a view when the LED lighting apparatus 1 according to the present invention is installed on the ceiling of the show window 4 having a curved surface.

  In FIG. 4, when installing the LED lighting fixture 1 in the curved parts 41 and 42 in front of a show window, the joint part 121 of the LED lighting fixture 1 is shown on a plane as shown to FIG. 2 (a), (b). Bend into a curved shape. Then, since the LED lighting fixture maintains its bent shape due to the rigidity of the aluminum composite plate, the mounting portion 122 of the aluminum composite plate 12 is provided with the mounting hole 114 of the LED module 11 every other LED module or every two LED modules. What is necessary is just to fix to the attachment surface of the ceiling 43 of a show window with the screw | thread etc. which let it pass.

  As described above, by using the LED lighting apparatus 1 of the present embodiment, the screwing work is reduced, so that the mounting work of the LED lighting apparatus can be reduced to half or one third. Further, the specific gravity of the aluminum composite plate is about one-fourth that of the aluminum plate and is lightweight, so that there is an advantage that it is easy to install and there is no need to apply special reinforcement to the mounting surface.

  Moreover, since the joint part 121 between the LED modules of the LED lighting device 1 can be extended, adjustments such that a portion where the illuminance is desired to be set high are narrow between the LED modules and a portion where the illuminance is low are widened between the LED modules. Easy to do. Alternatively, it is also possible to adjust the extension degree of the joint portion 121 while measuring the illuminance of the entire show window on site, so that it is not necessary to arrange the LED modules 11 more than necessary, which contributes to cost reduction. To do.

  Furthermore, since the LED lighting apparatus 1 according to the present invention uses an aluminum composite plate, its workability is high, and when the LED lighting apparatus 1 is too long with respect to the installation location, it is cut and adjusted at the joint portion 121. Can be easily done. In that case, it is possible to easily change the electrical line by short-circuiting the output-side terminals of the LED modules 11b that terminate at the lead wires 13.

  FIG. 5 is a diagram showing a state in which the LED lighting apparatus 1 according to the present invention is constructed when a building pillar is illuminated from below.

  In FIG. 5, the LED lighting fixture 1 which concerns on this invention is installed so that the pillar 5 shown with a broken line may be surrounded. Since the joint part 121 of the LED lighting device 1 can be twisted in the width direction as shown in FIG. 2 (d), the outer periphery of the column 5 is surrounded roundly and at the same time from the LED module 11 toward the column 5. It is easy to deform the joint 121 to direct the irradiation. In addition, since the state is maintained by the rigidity of the aluminum composite plate, it is possible to attach the LED lighting fixture 1 with the metal fitting 6 without preparing a conventional LED module mounting base. Both costs are greatly reduced.

  2C shows the extension of the joint part 121 so that the LED module 11 at the terminal end is removed and the attachment part 122 is bonded to the LED module attachment part 122 at the start end also when making a round of the column 5. Therefore, it is easy to illuminate the column 5 uniformly. At that time, it is necessary to short-circuit the output side terminals of the newly terminated LED module 11b with lead wires in order to form an electric circuit.

  In the present embodiment, the shape of the joint portion 121 is the single meandering path 15, but the shape is not limited to this, and the aluminum composite plate can be used for various shapes of joint portions 121 by taking advantage of good workability. Can be formed. FIG. 3 is a view showing another example of the joint 121.

  3, (a) increases the number of joints of the joint part 121 by one as compared with the joint part 121 shown in FIG. 1, and accordingly, the positions of the start point 12b and the end point 12d of the meandering path 15 are different from those of the aluminum composite plate. It is provided on the side. Thereby, while the extension distance of the joint part 121 increases, the twisting operation | work becomes easy and the twist angle with the adjacent LED module 11 can be increased. Further, since the number of joints is an even number, the same degree of bending can be formed in both the clockwise direction and the counterclockwise direction when bending on a plane. (B) is obtained by increasing the number of joints from (a), so that the extension distance of the joint portion 121 can be further increased, and the degree of curvature on the plane can be further increased. FIG. 3C shows two meandering paths 15, which reduces the extension distance of the joint 121 compared to FIG. 3B, but increases the holding force when the joint 121 is deformed. Since it can be increased, it is suitable for using a slightly larger LED module.

  In this embodiment, the thickness of the aluminum composite plate is 2.7 mm. However, the thickness is not limited to this, and the thickness of the aluminum plate or the resin core is changed according to the weight of the LED module to be used. It is also possible to increase the rigidity.

  In this embodiment, an aluminum composite plate is used. However, the present invention is not limited to this, and the metal plate member may be a metal composite plate using titanium, stainless steel, aluminum / zinc alloy, steel, or copper. When stainless steel, aluminum / zinc alloy or steel is used for the metal plate, the rigidity is increased but the weight is increased compared to the aluminum composite plate, and the heat conductivity is lowered and the heat dissipation effect of the LED module is reduced. It is preferable to use an LED module with a margin when more rigidity is required.

  Further, when titanium is used for the metal plate, it is not as rigid as the stainless steel composite plate, but is more rigid than aluminum, and heavier than the aluminum composite plate, but lighter than the stainless steel composite plate. However, since the thermal conductivity is lower than that of stainless steel, it is not suitable for use in an LED module having a large capacity.

  Furthermore, when copper is used for the metal plate, the thermal conductivity is higher than that of aluminum, so that it is suitable for use in a large capacity LED module. Thus, since each metal composite board has the characteristic, it is good to select according to an LED module and the environment to install.

  Moreover, in this Embodiment, although the constant current drive thing was used for the LED module 11, not only this but a constant voltage drive thing can also be used. In this case, it is not necessary to use a constant voltage power source as a power source and short-circuit the output side terminals of the terminal LED module 11b. For this reason, in order to adjust the length of the LED lighting apparatus 1 in the longitudinal direction, there is an advantage that it is only necessary to cut the joint portion 121 and remove the terminal lead wire.

  Furthermore, in the present embodiment, the LED module 11 has a structure in which the LED element having the LED element resin-sealed on the substrate is covered with the wide-angle lens 111. However, the present invention is not limited thereto, and there is no structure or lens that covers the narrow-angle lens. A structure with a cover is also possible.

  As described above, in the present embodiment, the LED lighting apparatus 1 is a linear aluminum composite in a state where the LED module 11 having the LED elements attached to the substrate is connected by the lead wires 13 for energization at predetermined intervals. It is formed in the joint portion 121 by being provided with a joint portion 121 that is attached to the plate 12 and provided with a plurality of slits in the width direction in the portion of the aluminum composite plate 12 between the LED modules 11 to form the meandering path 15. Since the joint of the meandering path 15 is flexible and extensible, the LED lighting apparatus can be easily and efficiently operated on a complicated surface by bending, twisting, or extending the joint 121. Can be attached.

  Further, in this embodiment, the joint portion 121 is one meandering path 15, but by using two meandering paths 15 and increasing the number of joints of the meandering path 15, the joint portion 121 can be adapted to the use situation and installation environment. It is also possible to design a balance between rigidity, flexibility and extensibility.

(Embodiment 2)
FIG. 6 is an external view of the LED lighting apparatus according to Embodiment 2 of the present invention.

  In FIG. 6, differences from the first embodiment will be described below.

  In the LED lighting device 1 of the present embodiment, the aluminum composite plate 12 is not attached to the entire back surface of the LED module 11, and the LED module 11 is coupled to the extension 123 of the joint portion 121. As shown in FIG. 6, the joint 121 has a shape extending to the mounting hole 114 of the LED module 11, and includes a mounting portion 124 in which a hole 115 for mounting on the construction surface is formed.

  Thus, since the LED lighting fixture of this Embodiment 2 couple | bonds LED modules 11 with the rigid coupling part 121, it can maintain fixed rigidity as a whole.

  FIG. 7 is a diagram showing a mounting shape of the LED lighting apparatus according to Embodiment 2 of the present invention.

  As shown in FIG. 7, the LED lighting apparatus 1 according to the present embodiment also bends, stretches, and twists the joint of the joint portion 121 in the same manner as the first embodiment shown in FIG. It is possible.

  Thereby, the LED lighting fixture 1 in this Embodiment 2 can also be constructed | assembled on various curved surfaces and planes similarly to the construction example shown in FIG.4 and FIG.5.

  Moreover, since the LED lighting fixture of this Embodiment 2 is the shape which removed the attachment part with the LED module 11 in the aluminum composite board, it can be reduced in weight compared with the thing of Embodiment 1 to that extent.

  Furthermore, when it is desired to shorten the entire length of the LED lighting apparatus, it is possible to remove the joint portion 121 without cutting the aluminum composite plate 12, and the work is reduced.

  However, since the heat dissipation effect by the aluminum composite plate is lost, it is not suitable for a large-capacity LED module with a large amount of heat dissipation.

  INDUSTRIAL APPLICABILITY The present invention is useful for an LED lighting apparatus, and is suitable for freely responding to the mounting shape and the size of the mounting surface at a construction site.
