Description

  The present invention relates to a light emitting element module, a light emitting device, and a method for installing a light emitting element module.

In recent years, linear light-emitting devices in which a plurality of light-emitting element modules each having a light-emitting element such as an LED element as a light source are connected by wiring have been used. Such a light emitting device is used for, for example, a display board, a guide board, or an advertisement signboard installed indoors or outdoors.
Some signboards have the shape of characters and symbols. In such a signboard, a light-emitting device in which the light-emitting element modules as described above are connected in a line shape follows the shape of the characters and symbols. It is attached. Normally, the length of the wiring between the light emitting element modules of the light emitting device is set to be longer than the required distance between the modules, and therefore the wiring length depends on the shape of the letter or symbol and the light emitting element spacing. The length dimension may be adjusted short. In this case, the length of the wiring can be adjusted to be short by bending the wiring, but the bent wiring does not look good. Further, in a signboard provided with a surface plate at a position facing the light emitting direction of the light emitting element, if the wiring is bent toward the surface plate side, there is a problem that the wiring is reflected on the surface plate surface of the signboard. Furthermore, in the case of a signboard that does not have a surface plate at a position opposite to the light emitting direction of the light emitting element, the bent wiring partially blocks the light emitted from the light emitting element, thereby causing partial variations in illuminance. And shadows may appear on the light. In such a case, for example, if the wiring bent by adjusting the length dimension is fixed to the signboard case with pins or the like, the reflection is eliminated. Because it is necessary to install and install the signboard, it takes a lot of time and work.

Therefore, measures have been proposed to try to solve these problems.
For example, Patent Literature 1 describes a lighting device including a plurality of light emitting element holders that accommodate light emitting elements and a wiring cord connected to the light emitting element holder. In the illuminating tool of Patent Document 1, the light emitting element holder is disposed in the accommodating space formed by the frame and the cap material, and the wiring cord is used for the light emitting element by turning the light emitting element holder around the axis. The length of the wiring cord that is partially housed along the holder and extends from the frame is adjusted to be short. For this reason, the wiring cord does not bend toward the display side, and reflection and complexity of construction can be reduced.

Utility Model Registration No. 3150493

In the illuminator of Patent Document 1, a wiring cord is connected in a vertical direction from the outer periphery of the light emitting element holder that is substantially circular in plan view, and the wiring cord extends from a slit in the side wall portion of the light emitting element holder. As described above, when the light emitting element holder is turned around the axis to adjust the length dimension of the wiring cord, the wiring cord is forcibly bent in the circumferential direction of the side wall near the portion extended from the slit. It is done. The wiring cord is a wire harness covered with a silicone-based resin, and extends vertically from the outer periphery of the holder. Therefore, the wiring cord swells at the folded portion and cannot be wound along the circumferential direction of the side wall portion. For this reason, the wiring cord cannot be accommodated in the limited space within the accommodation space formed by the frame body and the cap material, and the length of the wiring cord cannot be easily adjusted. Problems may arise. Therefore, it is necessary to make the frame body and the cap material large in consideration of the swelling of the wiring. Further, a load caused by the bending of the wiring cord is increased, and the wiring cord may be disconnected.
Furthermore, in the said lighting fixture, three members, a holder, a frame, and a cap material, are required, and not only it is necessary to prepare many members at the time of installation construction, but also after adjusting the length of the wiring cord at the time of construction. Three members must be assembled, and when many light emitting elements are used, it takes time to assemble one by one, which may require a lot of work time.

  The object of the present invention is to easily adjust the length of the wiring while preventing the reflection due to the bulging of the wiring, partial variations in illuminance, and shadows, reducing the number of members, and simplifying the installation work. It is to provide a light emitting device module, a light emitting device, and a method for installing the light emitting device module.

And wiring is connected to the board | substrate or the light emitting element, and is taken out from the outer periphery of the wall board through the extraction port.
Therefore, when a plurality of light emitting element modules are connected by wiring and the interval between the light emitting element modules is adjusted, the wiring can be wound in a direction along the outer periphery of the wall plate. Thus, the wiring cord can be prevented from being bent and swollen. In addition, it is not necessary to assemble three members of the holder, the frame body, and the cap material as in the prior art, and the number of members can be reduced.
Therefore, according to the light emitting element module of the present invention, it is possible to easily adjust the length of the wiring while preventing reflection due to the swelling of the wiring, partial illuminance variation, generation of shadows, and the like. Further, the reduction in the number of members can simplify the installation work of the light emitting element module, and can also realize cost reduction. Furthermore, according to the light emitting element module of the present invention, it is possible to reduce the possibility that the wiring is disconnected.
In the present invention, surrounding a light emitting element with a wall plate includes a case where the entire periphery of the light emitting element is surrounded or a case where the light emitting element is partially or intermittently surrounded. The wiring may be connected to the substrate and electrically connected to the light emitting element by a lead wire or the like on the substrate, or may be directly electrically connected to the light emitting element.

  And in the light emitting element module of the present invention, if the wiring fixing means for fixing the wiring wound along the outer periphery of the wall plate is provided, the wiring is surely wound around the outer periphery of the wall plate. The accommodation is improved, and reflection due to the swelling of the wiring, partial variations in illuminance, generation of shadows, and the like can be more reliably prevented. In the present invention, the fixing of the wiring by the wiring fixing means means that the wiring board is completely fixed to the outer periphery of the wall plate, or that the distance between the light emitting element modules is adjustable after being temporarily fixed. Including cases.

Since the light-emitting device of the present invention is configured by connecting a plurality of the light-emitting element modules of the present invention, the light-emitting element can be mounted at a desired interval without bending the wiring with respect to a mounting body such as a character signboard to which the light-emitting device is attached Can be installed. Therefore, according to the light emitting device of the present invention, it becomes easy to adjust the interval and the number of arrangement of the light emitting element modules, and can flexibly cope with required brightness, cost, and the like. Of course, as described above, it is possible to prevent reflection due to the swelling of the wiring, partial variations in illuminance, generation of shadows, and the like.
Further, according to the light emitting device, even when the mounting body has a shape such as a character or a symbol, the wiring can be arranged without forcibly bending it in the direction in which the load is applied, and disconnection of the wiring can be prevented.

[First embodiment]
(Light emitting element module and light emitting device)
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Examples thereof include a synthetic resin plate, a glass plate, a wood plate, a paperboard, and a cardboard base paper. be able to. The members may be used not only independently, but may be used in combination as a multi-layer laminate. In that case, if the surface on which the electrical wiring portion is provided is insulative, the other layers are non-metallic plates and the like. It may be insulating.
Examples of the material of the synthetic resin plate include acrylic resin, polycarbonate resin, polyethylene resin, polypropylene resin, polyvinyl chloride resin, acrylonitrile / butadiene / styrene resin, polyester resin, polyimide resin, epoxy resin, polyurethane resin, and the like. May be used alone or in combination.

Although the shape of the board | substrate 21 is not specifically limited, In this embodiment, it is a plate-shaped member formed in the substantially circular shape.
The thickness dimension of the substrate 21 is preferably 50 μm or more and 30 mm or less, and more preferably 300 μm or more and 20 mm or less. If the thickness dimension is less than 50 μm, the substrate 21 is thin, so that the strength for supporting the LED element 30 and the like may be insufficient. Furthermore, if the substrate 21 is thin, depending on the material, the substrate 21 may be torn or bent, and the electrical wiring portion may be short-circuited or disconnected, causing a problem in power supply to the LED element 30. When the thickness dimension exceeds 30 mm, the substrate 21 becomes thick, the weight of the LED module 10 as a whole increases and the workability decreases, or the thickness dimension of the light emitting device 1 increases, Thinning may be difficult.
On the back surface of the substrate 21, that is, the surface opposite to the surface on which the LED elements 30 are installed, a fixing member for fixing the light emitting device 1 to an installation target (signboard or the like) is provided. Is preferred. As the fixing member, a double-sided adhesive tape, an adhesive, or the like can be exemplified, but if a screw, a nail, a thumbtack or the like is used, the position of the LED element 30 is determined and then the holder is rotated to adjust the length of the wiring 40 You can also

The maximum height to the upper end of the wall plate 22 (the width of the wall plate) is not particularly limited as long as the wiring 40 can be wound around the outer periphery, but is preferably 2 mm or more and 30 mm or less, preferably 3 mm. It is more preferably 20 mm or less and particularly preferably 5 mm or more and 15 mm or less. If the width dimension of the wall plate is less than 2 mm, the wiring 40 is protruded from the wall plate if it is meandered even slightly when winding because the width is narrow, or if the width is narrower than the wiring 40, the wiring 40 May be difficult to fit around the periphery and wind well. When the width dimension of the wall plate exceeds 30 mm, the height of the LED module increases, the thickness of the signboard increases, and the signboard may be increased in size.
The member constituting the wall plate 22 can be appropriately selected from the same materials as those of the substrate 21 exemplified above. The thickness of the wall plate 22 is preferably 50 μm to 15 mm, more preferably 500 μm to 10 mm, and particularly preferably 1 mm to 5 mm. If the thickness dimension of the wall plate 22 is less than 50 μm, the wiring 40 is bent when the wiring 40 is wound because it is thin and has no stiffness, and the wiring may not be wound neatly. If the thickness of the wall plate 22 exceeds 15 mm, the weight and size of the LED module increase, which may lead to an increase in the size of the signboard.

In the present embodiment, the wiring extraction portions 23 are provided at two locations on the outer periphery of the wall plate 22 and are located at positions facing each other. The wiring extraction portion 23 is formed to bulge outward from the outer periphery of the wall plate 22, and the outer periphery of the wiring extraction portion 23 is curved.
The wiring outlet 23 is formed with an outlet 231 that opens in a direction along the outer periphery of the wall plate 22 so that the wiring 40 can be inserted through the outlet 231 from the internal space surrounded by the substrate 21 and the wall plate 22. It has become. Therefore, the wiring 40 is taken out from the outer periphery of the wall plate 22 through the outlet 231, and extends along the outer periphery of the wall plate 22.
As a member constituting the wiring extraction portion 23, it can be appropriately selected from the same materials as those of the substrate 21 and the wall plate 22 exemplified above.

The wiring 40 includes a positive electrode line 41 and a negative electrode line 42. In the present embodiment, as shown in FIG. 1, the wiring 40 is taken out from the outlet 231 of the wiring extraction portion 23 in a state where the positive electrode line 41 and the negative electrode line 42 are arranged in the vertical direction. In FIG. 1, the negative electrode wire 42 is arranged on the lower side and the positive electrode wire 41 is arranged on the upper side, but the arrangement may be reversed. Moreover, the positive electrode line 41 and the negative electrode line 42 may be arrange | positioned in the horizontal direction. Therefore, it is preferable that the outlet 231 of the wiring extraction portion 23 is formed in a shape that matches the arrangement state of the positive electrode line 41 and the negative electrode line 42.
One end of the positive electrode line 41 and the negative electrode line 42 is connected to the substrate 21 of the LED module 10, and the other end of the positive electrode line 41 and the negative electrode line 42 is connected to the substrate 21 of another LED module 10. 10 are connected.

As the positive electrode line 41 and the negative electrode line 42, wiring used for normal electric wiring can be used, and gold wire, silver wire, copper wire, aluminum wire, nickel wire and the like are exemplified. The diameters of the positive electrode wire 41 and the negative electrode wire 42 are preferably 100 μm or more and 10 mm or less, and more preferably 500 μm or more and 5 mm or less.
Furthermore, as the positive electrode wire 41 and the negative electrode wire 42, it is preferable to use a coated wire whose periphery is covered with an insulating material. In this embodiment, a coated copper wire is used. Moreover, in order to make it easy to wind the positive electrode wire 41 and the negative electrode wire 42 along the outer periphery of the wall plate 22, or to make it easy to extend in various directions, the positive electrode wire 41 and the negative electrode wire 42 are flexible. It is preferable to form with a material. Moreover, you may use the double covering wiring which coat | covered the coated positive electrode wire 41 and the negative electrode wire 42 further collectively.

In the present embodiment, two LED elements 30 are provided on the substrate 21. However, the number and arrangement interval of the LED elements 30 are appropriately designed according to the luminance, irradiation area, cost, and the like required for the LED module 10 and the light emitting device 1.
The LED element 30 is electrically connected to an electrical wiring portion provided on the substrate 21. Electric power for causing the LED element 30 to emit light is supplied from an external power source to the substrate terminal portion of the substrate 21 through the wiring 40, and is supplied to the LED element 30 through the electric wiring portion.
It is preferable that an LED sealing material is disposed on the surface of the substrate 21 on which the LED elements 30 are disposed. This LED sealing material also plays a role of waterproofing treatment, improving and stabilizing the connection strength between the LED element 30 and the electric wiring part, and further protecting and reinforcing against external impact on the LED element 30. Yes.
As LED sealing material, sealing resin currently used for sealing of light emitting elements, such as an LED element, can be used, for example. Sealing resins include silicone resins (alkyl-modified silicone resins, epoxy-modified silicone resins, alkyd-modified silicone resins, acrylic-modified silicone resins, polyester-modified silicone resins, phenylsilicone resins, dimethylsilicone resins, etc.), epoxy resins, acrylic resins, Examples include methacrylic resins and urethane resins.
Moreover, as LED sealing material, in order to radiate | emit the light radiate | emitted from the LED element 30 to the exterior, it is comprised with the transparent material. In this case, the LED sealing material may be colorless and transparent, or may be colored within a range that does not impair the light transmissivity, thereby providing a light texture effect. Moreover, as long as the emitted light from the LED element 30 is not blocked too much, it may be partially transparent, and other portions may be colored to limit light transmission.

  In the present embodiment, the structural unit of one LED module 10 includes a holder 20 (substrate 21, wall plate 22, and wiring extraction portion 23), an LED element 30 provided on the substrate 21 inside the holder 20, and a substrate. 21 is a wiring 40 connected to 21. The other end of the wiring 40 (positive line 41 and negative line 42) of this one LED module 10 is connected to the substrate 21 of the other LED module 10 through the outlet 231 of the wiring extraction part 23 of the other LED module 10. Connected. In this way, the light emitting device 1 is configured by connecting the plurality of LED modules 10 by wiring.

(Installation method of LED module)
A method for installing the LED module 10 will be described.
As shown in FIG. 1, the LED module 10 before installation is in a state in which the wiring 40 is extended from the outlet 231 of the wiring extraction portion 23. When installing the LED module 10 in such a state on the installation target, the holder 20 of the LED module 10 is rotated in the in-plane direction of the substrate 21 and the wiring 40 is wound along the outer periphery of the wall plate 22.
In the present embodiment, when the holder 20 is rotated in the clockwise direction, the wiring 40 is wound along the outer periphery of the wall plate 22. Further, since the side surface of the wiring extraction portion 23 is curved as described above, the wiring 40 is wound around the outer periphery of the wiring extraction portion 23 in the same manner as the wall plate 22.
Thus, the length dimension of the wiring 40 which connects LED modules 10 is adjusted, and the several LED module 10 is installed in an installation target object. In addition, the winding dimension of the wiring 40 can be appropriately set according to the size of the installation object and the arrangement interval of the LED elements 30.

On the other hand, a case where a wiring cord is connected in the vertical direction from the outer periphery of the light-emitting element holder as in the prior art described in Patent Document 1 will be described.
In the case of such a conventional technique, the wiring cord 400 is connected in the vertical direction from the outer periphery of the light emitting element holder 200 as shown in FIG. The light emitting element holder 200 includes a substrate 210, a side wall portion 220 which is provided on the outer peripheral portion of the substrate 210 and is erected from the surface of the substrate 210, and an LED element 300 provided on the substrate 210. The wiring cord 400 extends in the vertical direction from the side wall portion 220 of the light emitting element holder 200. The extending direction of the wiring cord 400 is not perpendicular to the substrate 210 surface but perpendicular to the side wall 220 surface. In other words, the wiring cord 400 is connected in a direction perpendicular to the tangent to the curved side wall 220.
6B, when the length of the wiring cord 400 is adjusted by rotating the light emitting element holder 200, the wiring cord 400 is lifted from the side wall portion 220, and the gap space Z Produce. When the light emitting element holder 200 is further rotated to further wind the wiring cord 400 around the side wall portion 220, the wiring cord 400 is further wound on the wiring cord 400 in a state of being floated by the gap space Z. Not only becomes large, but also because the gap space Z is a convex portion, it cannot be wound neatly. Therefore, when the light emitting element holder 200 is accommodated in the accommodating space formed by the frame body and the cap material, the wiring cord 400 cannot be accommodated in the limited space in the accommodating space, and the length dimension is adjusted. It cannot be done easily. Therefore, it is necessary to form a large frame in consideration of the swelling of the wiring cord 400. In addition, the bent portion of the wiring cord 400 may increase a load caused by the bending, and the wiring cord 400 may be disconnected.

(Usage of light emitting device)
Next, a usage form of the light emitting device 1 will be described.
In the present embodiment, a case where the light emitting device 1 is installed on an L-shaped character signboard 50 as shown in FIG. 2 and used as a light source of the character-shaped light emitting signboard will be described as an example.
First, each LED module 10 which comprises the light-emitting device 1 is arrange | positioned along the L-shape of the character signboard 50. FIG. In the present embodiment, five holders 20 of the LED module 10 are arranged in the vertical direction L1 of the character sign 50. If five holders 20 are arranged with respect to the dimension in the vertical direction L1 with the wiring 40 as shown in FIG. 1 extended, if the wiring 40 is longer than the interval between the LED modules 10, the wiring 40 is bent. It will be in the state. In such a case, like the above-described method for installing the LED module 10, the holder 20 of the LED module 10 is rotated in the in-plane direction of the substrate 21, and the wiring 40 is wound along the outer periphery of the wall plate 22. Thus, as shown in FIG. 2, the holder 20 portion of the LED module 10 can be installed so as not to protrude in the longitudinal direction L1. Furthermore, in order to arrange four in the horizontal direction L2 of the character signboard 50, the LED module is directed from the holder 20 installed at the lowermost side in the vertical direction L1 toward the horizontal direction L2 (right direction) in FIG. 10 is installed. In this case, similarly, the wiring 40 can be installed so as not to bend by winding the wiring 40 along the outer periphery of the wall plate 22. In this way, the light emitting device 1 is installed on the L-shaped character signboard 50, and the character signboard 50 is used by being attached to the outer wall or the like of the store.
In addition, the wiring 40 of the LED module 10 installed in one end among the several LED modules 10 which comprise the light-emitting device 1 is connected with a power supply. Power is supplied from the power source, and power is supplied to the LED elements 30 of the LED modules 10 through the wiring 40. In addition, among the plurality of LED modules 10 constituting the light emitting device 1, the wiring 40 of the LED module 10 installed at the other end is wound along the outer periphery of the wall plate 22. The treatment may not be performed, or it may be sealed with a resin or the like. Further, the wiring 40 may be removed from the substrate 21 of the holder 20.

(Effects of the first embodiment)
According to the LED module 10 and the installation method of the LED module 10 of the present embodiment, the following effects are obtained.
In the LED module 10, a wiring extraction portion 23 is provided on the outer periphery of the wall plate 22 of the holder 20, and the wiring extraction portion 23 has an extraction opening 231 that opens in a direction along the outer periphery of the wall plate 22. The wiring 40 is taken out from the outer periphery of the wall plate 22 through the outlet 231.
Therefore, when the light emitting device 1 is configured by connecting a plurality of LED modules 10 with the wiring 40 and the interval between the LED modules 10 is adjusted, the wiring 40 can be wound in a direction along the outer periphery of the wall plate 22. It is possible to prevent the wiring cord 400 from being bent as shown in FIG. 6 (B) to form the gap space Z and swell.
Therefore, according to the LED module 10, the length dimension of the wiring 40 can be easily adjusted while preventing the reflection due to the swelling of the wiring 40, partial illuminance variation, generation of shadows, and the like.
Moreover, the LED module 10 can wind the wiring 40 around the holder 20 composed of the substrate 21, the wall plate 22, and the wiring extraction portion 23, and the holder, the frame, the cap material, and the like as in the prior art. It is not necessary to assemble these three individual members, and the number of members can be reduced.
Therefore, according to the LED module 10, the installation work can be simplified by reducing the number of members.
Furthermore, according to the LED module 10, the possibility that the wiring 40 is disconnected can be reduced.

In the LED module 10, the outer periphery of the wiring extraction portion 23 is curved. Therefore, the wiring 40 can be wound along the curved outer periphery of the wiring extraction portion 23 in the same manner as the wall plate 22.
Therefore, according to the LED module 10, even when the winding dimension of the wiring 40 is increased, the wiring 40 is prevented from being bent and swollen, and the length dimension can be easily adjusted. Disconnection can be prevented.

Further, according to the light emitting device 1 in which a plurality of LED modules 10 are connected, the holder 20 can be installed at a desired interval with respect to the character signboard 50 without bending the wiring 40. Therefore, it becomes easy to adjust the interval and the number of arrangement of the LED modules 10, and can flexibly cope with required brightness, cost, and the like.
In addition, the L shape shown in FIG. 2 has a portion bent in the vertical direction L1 and the horizontal direction L2, but according to the light emitting device 1, the wiring 40 can be arranged without forcibly bending it in the direction in which the load is applied, Disconnection of the wiring 40 can be prevented.

  The installation form of the light emitting element module and the light emitting device is not limited to a flat arrangement. For example, it may be disposed along a curved surface or a spherical surface, or may be disposed along a polyhedral surface such as a rectangular parallelepiped or a triangular pyramid.

The configuration of the light emitting element module is not limited to that described in the first embodiment.
For example, as shown in FIGS. 5A and 5B, the LED modules 13 and the LED modules 14 may be connected by a connector 43.
In the LED module 13 shown in FIG. 5A, a male connector 43 </ b> A is attached to the end of the wiring 40 extending from the outlet 231 of one wiring extraction portion 23 of the holder 20. Further, a male connector 43A and a female connector 43B that can be attached to and detached from the outlet 231 of the other wiring extraction portion 23 are attached. When a plurality of LED modules 13 are connected, both the LED modules 13 are electrically connected by connecting the male connector 43A of the LED module 13 to the female connector 43B of another LED module 13.
Further, in the LED module 14 shown in FIG. 5B, the male connector 43 </ b> A is attached to the end portion of the wiring 40 extending from the outlet port 231 of the one wiring outlet portion 23 of the holder 20.

When a plurality of LED modules 14 are connected, both the LED modules 14 are electrically connected by connecting the male connector 43A of the LED module 14 to the female connector 43B of another LED module 14.
In addition, you may connect the LED module 13 and the LED module 14 with the connector 43. FIG.

As the male connector and the female connector, it is preferable to use waterproof removable connectors. Examples of the detachable connector include a connector that fits a male connector and a female connector as described above and electrically connects them. Furthermore, if it is set as the structure which hold | maintains a fitting state by engagement with the latching piece provided in the housing of the male connector, and the latching hole provided in the housing of the female connector, with respect to the latching hole of a latching piece, By releasing the engagement, the male connector and the female connector can be easily detached. And if a male connector and a female connector are fitted and a terminal part is covered with a housing and it is set as a watertight structure, waterproofness can also be provided. That is, attachment / detachment and waterproofing can be easily performed. In addition, although it does not specifically limit as a connector which has waterproofness and is detachable and can be attached or detached easily, For example, the waterproof connector (CB01A5-02) made from a Sumitech Co., Ltd. can be used.
Therefore, by using a light emitting element module with a connector as described above, a plurality of light emitting element modules can be detachably connected, and the number of light emitting element modules constituting the light emitting device can be freely adjusted.

Further, the shape of the substrate is not limited to the shape described in the above embodiment. For example, in a plan view of the light emitting element module, the substrate may have an elliptical shape or a rounded quadrangular shape. Thus, by providing the wall plate on the outer peripheral portion of the rounded substrate, the outer periphery of the wall plate can be curved, and the wiring can be wound in a direction along the outer periphery of the curved wall plate. In the first embodiment described above, an example in which a wall plate is provided on the outer peripheral portion of the substrate has been described as an example. It is good also as an aspect surrounding an element.
In addition, a rectangular shape such as a square or a rectangle, a polygonal shape such as a triangle, pentagon, or hexagon, a circular shape, an elliptical shape, an indefinite shape, or the like may be selected in various ways.
Further, the substrate is not limited to a flat plate, and may be a substrate on which irregularities are formed. In the said embodiment, seeing with sectional drawing of an LED module, although the LED element was provided in the flat board | substrate and demonstrated and demonstrated the example arrange | positioned at the lower end part side of the up-down direction of a wall board, It is not limited to an aspect.
For example, it is good also as an aspect which arrange | positions the light emitting element in the upper end part side of the up-down direction of a wall board by forming the part raised on the board | substrate and providing an LED element (light emitting element) in this part.

In addition, since the substrate reflects or absorbs light from the light-emitting element, brightness adjustment and hue can be changed according to the color of the surface of the substrate, and a light texture can be produced. Specifically, if the color of the surface of the substrate is white, the brightness increases, and if it is black, a dark impression can be given. Also, if the color is red, a warm effect is possible, and if the color is blue, a cool and cool effect is possible.
Examples of the method for coloring the substrate include a method in which dyes and pigments are blended with the raw materials of these members, a method in which ink of a desired color is printed on the surface of each member, and a paint is applied. It is done. The sealing material and the top plate can be colored in the same manner to produce a texture.

The substrate can have a single layer structure made of the above members or a stacked structure formed by laminating a plurality of members.
When the substrate has a stacked structure, for example, a structure in which a synthetic resin plate, an adhesive layer, and a metal plate are stacked in order from the surface side on which the light emitting element is mounted can be employed.
As the synthetic resin plate, it is preferable to use a resin plate formed of the materials exemplified above. For example, a resin plate made of polyethylene terephthalate resin, which is a kind of polyester resin, is preferable.
The adhesive layer is not necessarily required as long as the material can directly bond the synthetic resin plate and the metal plate by a heat laminating process or the like. However, it is preferable to provide an adhesive layer in order to adhere the members to be laminated and maintain the laminated state when the substrate is laminated. The material of the adhesive layer is not particularly limited as long as it is a material capable of maintaining the laminated state between the laminated members, and is appropriately selected according to the combination of the laminated members. Examples of the adhesive for the adhesive layer include adhesives mainly composed of acrylic, silicone, rubber, polyester, polyethylene, and polyurethane resins. Among these, acrylic adhesives are preferable because they are excellent in terms of a balance between adhesive strength and durability. A double-sided tape may be used as the adhesive layer. As the adhesive resin component of the double-sided tape, those exemplified as the material of the adhesive layer can be used. The thickness dimension of the adhesive layer is preferably 1 μm or more and 1 mm or less, and more preferably 5 μm or more and 500 μm or less. If the thickness dimension is less than 1 μm, the adhesiveness may be insufficient, and if it exceeds 1 mm, the adhesive may protrude from the side surface, which is not preferable from the viewpoint of reducing the weight of the substrate.
The metal plate is laminated to the insulating synthetic resin plate via an adhesive layer, and plays a role of improving the strength of the resin plate and radiating heat accompanying light emission of the light emitting element mounted on the resin plate side. Fulfill. Examples of the material of the metal plate include gold, silver, copper, nickel, aluminum, platinum (platinum), and stainless steel. If an aluminum plate is used as a metal plate, even if a laminated substrate is used, it is possible to improve heat dissipation and reduce the weight of the light emitting element module.

  The top plate provided facing the substrate of the holder may be provided on the holder 20 of the LED module 10 of the first embodiment in order to protect the LED element from impact, humidity, and the like.

Further, in the third embodiment, the wiring fixing means has been described by taking an example in which both the substrate protruding portion 25A and the top plate protruding portion 26A are provided, but the present invention is not limited to this. Either one of the protrusions may be formed.
Further, in the aspect such as the first embodiment and the second embodiment in which the top plate 24 is not attached, the substrate overhanging portion 25 and the substrate protruding portion 25A are formed only on the substrates 21 and 21A to form the wiring fixing means. The wiring 40 may be accommodated and fixed.
Moreover, even if it is an aspect which provides both the board | substrate protrusion part 25A and the top-plate protrusion part 26A, the board | substrate protrusion part 25A and the top-plate protrusion part 26A do not necessarily need to be opposingly arranged, and are arrange | positioned alternately. An aspect may be sufficient.

Further, in the second embodiment and the third embodiment, as the wiring fixing means, the groove shape has been described as an example. However, the wiring fixing means is not limited to this aspect, and is particularly limited as long as the wound wiring can be fixed. Not.
For example, a clip-shaped wiring fixture may be used. A wiring fixture is temporarily fixed in the middle of the wiring, and the wound wiring is held and fixed together with the wall plate by the wiring fixture. For this reason, the wound wiring can be easily wound around and fixed to the outer periphery of the wall plate without forming the board overhanging portion, wall plate overhanging portion, top plate overhanging portion, substrate protruding portion, top plate protruding portion, etc. Therefore, it is possible to more reliably prevent the reflection of wiring, the partial variation in illuminance, the generation of shadows, and the like. In addition, as a wiring fixing tool, it is not limited to the fixing tool of the shape and mechanism like a clip.

The substrate and the wall plate may be formed integrally or may be formed separately. When it is formed separately, it may be detachable.
Also, when the top plate is provided, the substrate, wall plate and top plate may be integrally formed. However, the manufacturing process of the holder, the light emitting element is accommodated in the internal space, and the wiring is connected to the substrate. In consideration of the process to be performed, it is preferable that it is formed separately. In the case of being formed separately, the substrate and the wall plate may be integrally formed, and the top plate may be attached after the light emitting element is accommodated or the wiring is connected. On the other hand, after the light emitting element is accommodated and the wiring is connected to the substrate on the flat plate, the integrally formed wall plate and top plate may be attached so as to cover the light emitting element on the substrate. Furthermore, it is good also as an aspect which forms a holder by forming a wall board in a board | substrate and a top plate, respectively, and connecting the edge part of the wall board of the said board | substrate and the said top plate mutually.
The substrate overhanging portion, wall plate overhanging portion, top plate overhanging portion, substrate protruding portion and top plate protruding portion may be detachably formed separately, but from the viewpoint of workability and handleability, Each of them is preferably formed integrally with the substrate, the wall plate, and the top plate.

  The light-emitting element module of the present invention can be used for lighting such as a ceiling, a wall, and a floor, and a surface light source such as a backlight such as a signboard, a vending machine, and a display shelf.
