Description

  The present invention relates to a light emitting device and a lighting device including the same.

  2. Description of the Related Art In recent years, lighting devices (LED lighting) using LEDs (Light Emitting Diodes) are rapidly spreading from the viewpoint of energy saving. Conventionally, as this kind of LED illumination, a long illuminating device including a long casing and an LED module arranged in the casing is known (for example, Patent Document 1). The LED module mounted on the long illuminating device includes, for example, a long substrate and a plurality of LED elements mounted linearly on the substrate along the longitudinal direction of the substrate.

JP 2012-84367 A

  For LED lighting, a power supply built-in illumination device that incorporates a power supply circuit composed of a plurality of circuit elements has been proposed. In the power supply built-in lighting device, the LED module is turned on by converting AC power supplied from an external AC power source into DC power by a power supply circuit.

  Furthermore, in a power supply built-in lighting device, an LED module in which an LED element and a circuit element constituting a power supply circuit are mounted on a single substrate has been studied in order to make a long casing thin.

  Such power supply to the LED module is performed using connection terminals (connectors) provided on a substrate on which the LED elements and circuit elements are mounted. The connection terminal is provided at an end portion of the substrate and is electrically connected to the circuit element and the LED element by a pattern wiring formed on the substrate.

  The connection terminal of the substrate and the external AC power source are electrically connected via an electric wire such as a lead wire. Specifically, one end of the electric wire is electrically and mechanically connected to the connection terminal, and the other end of the electric wire is an end attached to the longitudinal end of the elongated casing. It is pulled out of the illumination device from the through hole of the cap and is electrically connected to an external AC power source. As a result, AC power from the external AC power supply is input to the connection terminal via the electric wire and supplied to the power supply circuit (circuit element).

  In addition, the end of the long substrate in the LED module often extends to the vicinity of the end of the long casing so as not to cause a dead space in the casing. However, in this case, the connection terminal provided at the end of the substrate exists near the end of the housing (that is, near the end cap). As a result, the connection terminal and the end of the housing come close to each other, and the electric wire connected to the connection terminal may be bent.

  When the electric wire bends, a force for peeling the connection terminal from the substrate is generated, and there is a problem that a connection failure between the connection terminal and the substrate occurs. In addition, when the electric wire is bent, the light emitted from the LED element is shaded by the bent electric wire, and the light distribution characteristic of the lighting device may be deteriorated.

  On the other hand, if the electric wire is shortened in order to suppress the bending of the electric wire, when assembling the lighting device, it becomes difficult to connect the other end of the electric wire in a state where one end is connected, and the assembly work efficiency is reduced. . For this reason, it is necessary to give a certain amount of redundancy (surplus) to the electric wires in consideration of assembly work efficiency.

  The present invention has been made to solve such a problem, and provides a light emitting device and a lighting device that can suppress bending of an electric wire connected to a connection terminal without lowering the assembly work efficiency of the lighting device. The purpose is to do.

  In order to achieve the above object, one embodiment of a light-emitting device according to the present invention includes a long substrate, a plurality of light-emitting elements arranged linearly on the substrate along the longitudinal direction of the substrate, Are arranged on one side of the element row that is a row of the plurality of light emitting elements, and are arranged on the substrate along the element row, and the substrate. And a power line for sending AC power supplied to the first connection terminal to the second connection terminal, and power for causing the light emitting element to emit light by the AC power supplied to the first connection terminal. And a plurality of circuit elements constituting a circuit for generating the first connection terminal, and a distance between the first connection terminal and the second connection terminal is shorter than a length of the element row.

  One embodiment of a lighting device according to the present invention includes the above light-emitting device, and an electric wire is connected to the connection terminal of the light-emitting device.

  The bending of the electric wire connected to the connection terminal can be suppressed without reducing the assembly work efficiency of the lighting device.

As shown in FIG. 4A, the first connection terminal 131 and the second connection terminal 132 are arranged on the substrate 110. The first connection terminal 131 and the second connection terminal 132 are fixed to the first surface 110 a of the substrate 110.

  The first connection terminal 131 is disposed at one end in the longitudinal direction of the substrate 110, and the second connection terminal 132 is disposed at the other end in the longitudinal direction of the substrate 110. In addition, each of the first connection terminal 131 and the second connection terminal 132 is arranged on one side (circuit element 140 side) of an element row that is a row of the plurality of light emitting elements 120. Specifically, both the first connection terminal 131 and the second connection terminal 132 are on the long side (the shorter long side) where the notch 111 is provided, with respect to the element row of the light emitting element 120. Has been placed.

  Further, the first connection terminal 131 and the second connection terminal 132 are arranged at a predetermined interval along the longitudinal direction of the substrate 110. Specifically, the first connection terminal 131 and the second connection terminal 132 are arranged so as to sandwich a plurality of circuit elements 140 arranged in the longitudinal direction of the substrate 110. That is, the first connection terminal 131 and the second connection terminal 132 are arranged apart from each other with a space for arranging the plurality of circuit elements 140 constituting the power supply circuit 140a.

  In the present embodiment, the distance between the first connection terminal 131 and the second connection terminal 132 is shorter than the length of the element row of the light emitting elements 120. Specifically, the first connection terminal 131 is located closer to the center than the light emitting element 120 at one end of the element row of the light emitting element 120, and the second connection terminal 132 is at the other end of the element row of the light emitting element 120. It is located closer to the center than the light emitting element 120. That is, the light emitting element 120 at one end of the element row of the light emitting element 120 is located outward from the first connection terminal 131, and the light emitting element 120 at the other end of the element row of the light emitting element 120 is from the second connection terminal 132. Is also located outside.

  The first connection terminal 131 and the second connection terminal 132 are connector terminals to which electric wires such as lead wires are connected. Specifically, the first connection terminal 131 and the second connection terminal 132 are fast connection terminals. That is, by inserting the electric wires into the electric wire insertion holes of the first connection terminal 131 and the second connection terminal 132, the electric wires inserted into the first connection terminal 131 and the second connection terminal 132 become the first connection terminal 131 and the second connection terminal 132, respectively. The first connection terminal 131 and the second connection terminal 132 are electrically and mechanically connected by contact pressure with a metal plate or the like in the connection terminal 132. As shown in FIGS. 2 and 4, each of the first connection terminal 131 and the second connection terminal 132 is arranged so that the wire insertion hole faces inward, but this is not restrictive.

  In the present embodiment, each of the first connection terminal 131 and the second connection terminal 132 is a pair. Specifically, one of the pair of first connection terminals 131 is an L-side terminal, and the other is an N-side terminal. One of the pair of second connection terminals 132 is an L-side terminal, and the other is an N-side terminal.

  The first connection terminal 131 is an input side terminal to which power is input from the outside of the LED module 100. That is, the first connection terminal 131 is a power receiving terminal that receives power from the outside of the LED module 100. Specifically, AC power for causing the light emitting element 120 to emit light is input to the first connection terminal 131.

  As shown in FIG.1 and FIG.2, the electric wire 400 (refer FIG. 2) is connected to the 1st connection terminal 131 electrically, for example with an external commercial power supply. As a result, commercial power AC power is input to the first connection terminal 131. In this case, a pair of electric wires 400 is connected to the pair of first connection terminals 131. The electric wire 400 is, for example, a VVF cable.

  The second connection terminal 132 is an output side terminal that outputs power to the outside of the LED module 100. That is, the second connection terminal 132 is a power transmission terminal that transmits power to the outside of the LED module 100. An electric wire is electrically and mechanically connected to the second connection terminal 132, and electric power is transmitted from the second connection terminal 132 to the outside via the electric wire.

  The pair of first connection terminals 131 and the pair of second connection terminals 132 are electrically connected by a pair of feed wirings 161. Specifically, the L side terminal of the first connection terminal 131 is connected to the L side terminal of the second connection terminal 132 via one of the pair of first feed wires, and the N side of the first connection terminal 131. The terminal is connected to the N-side terminal of the second connection terminal 132 through the other of the pair of feed wirings 161.

  In the present embodiment, the first connection terminal 131 and the second connection terminal 132 have the same potential except for the resistance component of the feed wiring 161. Thereby, the AC power input to the first connection terminal 131 is supplied to the second connection terminal 132 with the AC waveform as it is without changing the frequency and the amplitude. For example, when AC 100V AC power is supplied to the first connection terminal 131, AC 100V AC power is supplied to the second connection terminal 132 as it is. Therefore, in this case, the second connection terminal 132 can transmit AC 100V AC power to the outside of the LED module 100.

  As shown in FIGS. 1 and 2, for example, an electric wire 410 is connected to the second connection terminal 132. As a result, the AC power transmitted from the first connection terminal 131 to the second connection terminal 132 through the feed wiring 161 can be output to the outside of the lighting device 1 via the electric wire 410. The electric wire 410 is the same as the electric wire 400, and is a VVF cable, for example. Note that, when the AC power supplied from the first connection terminal 131 to the second connection terminal 132 does not need to be output to the outside, the electric wire 410 may not be connected to the third connection terminal 133. That is, whether or not the electric wire 410 is used for the lighting device 1 is arbitrary.

  The AC power input to the first connection terminal 131 is also supplied to the power supply circuit 140a. For example, when AC 100V AC power is supplied to the first connection terminal 131, AC 100V AC power is supplied to the power supply circuit 140a. That is, the first connection terminal 131 also functions as a power supply terminal that supplies AC power to the power supply circuit 140a.

  As described above, in the LED module 100 according to the present embodiment, when AC power is supplied to the first connection terminal 131, AC power is supplied to the second connection terminal 132 through the feed wiring 161 and the power supply circuit 140a. AC power is supplied to

That is, the plurality of circuit elements 140 are arranged side by side with the plurality of light emitting elements 120.

That is, the plurality of circuit elements 140 include power supply circuit elements that constitute the power supply circuit 140a.

  In the present embodiment, since the LED module 100 is driven by the AC direct method, the plurality of circuit elements 140 constituting the power supply circuit 140a uses alternating current power supplied to the first connection terminal 131 as the light emitting element 120. Converts to direct current power for light emission. Therefore, the plurality of circuit elements 140 include, for example, a rectifying element that rectifies an AC voltage and converts it into a DC rectified voltage, and the plurality of light emitting elements 120 emit light according to the rectified voltage. DC power generated by the plurality of circuit elements 140 constituting the power supply circuit 140 a is supplied to each of the plurality of light emitting elements 120 via the first pattern wiring 150 formed on the substrate 110. The plurality of circuit elements 140 constituting the power supply circuit 140a include, for example, a capacitive element such as an electrolytic capacitor or a ceramic capacitor, a resistive element such as a resistor, a rectifier element, a noise filter, a diode, or a semiconductor element such as an integrated circuit element. It is.

As shown in FIG. 3, the opening 171 is partially formed in the insulating film 170 to partially expose the first pattern wiring 150. The first pattern wiring 150 exposed from the opening 171 becomes a connection land (element mounting portion). The light emitting element 120 and the circuit element 140 that are surface-mounted on the substrate 110 are solder-connected by lands of the first pattern wiring 150.

  As the insulating film 170, a white resin material (white resist or the like) having a high reflectance with a reflectance of about 98% may be used. Thereby, in addition to the improvement of the withstand voltage of the substrate 110 and the protection of the first pattern wiring 150, the light emitted from the light emitting element 120 can be reflected by the insulating film 170, thereby improving the light extraction efficiency of the LED module 100.

  One end of the feed wiring 161 is electrically connected to the first connection terminal 131, and the other end of the feed wiring 161 is electrically connected to the second connection terminal 132.

  Specifically, as shown in FIGS. 4B and 5A, in plan view, at least a part of the feed wiring 161 formed on the second surface 110b is formed on the first surface 110a. This overlaps at least a part of the first connection terminal wiring 151 formed. A contact hole is formed in the overlapping portion of the substrate 110, and the feed wiring 161 and the first connection terminal wiring 151 are electrically connected through the contact hole. Similarly for the second connection terminal wiring 155, the feed wiring 161 and the second connection terminal wiring 155 are electrically connected through a contact hole formed in the substrate 110.

  The feed wiring 161 is composed of two wirings. Each of the two feed wirings 161 has a constant width and is formed in a straight line. In the present embodiment, the two feed wirings 161 are formed in parallel along the longitudinal direction of the substrate 110. The lengths of the two feed wires 161 are different, but they may be the same length. In the present embodiment, the feed wiring 161 located on the inner side of the two feed wirings 161 is shorter than the feed wiring 161 located on the outer side.

  The element back wiring 162 and the intermediate wiring 163 function as a heat radiating member and radiate heat generated in the light emitting element 120 and the circuit element 140. Therefore, the element back wiring 162 and the intermediate wiring 163 may be in an electrically floating state without being electrically connected to the light emitting element 120 and the circuit element 140, but may be electrically connected to the light emitting element 120 and the circuit element 140. May be connected to each other.

  As shown in FIG. 4B, the element back wiring 162 is formed at a position overlapping the light emitting element 120 along the element row of the light emitting element 120 in plan view. That is, the element back wiring 162 is formed at a position facing away from the light emitting element 120 through the substrate 110. In the present embodiment, the element back wiring 162 is formed for each light emitting element 120. That is, a plurality of element back wirings 162 are formed along the element row of the light emitting elements 120. The element back wiring 162 may be formed at a position overlapping the circuit element 140 in plan view.

  The intermediate wiring 163 is formed between the element back wiring 162 and the feed wiring 161. The intermediate wiring 163 extends along the longitudinal direction of the substrate 110. Specifically, the intermediate wiring 163 is a straight wiring formed in a straight line. Further, in the present embodiment, the intermediate wiring 163 is shorter than the feed wiring 161, but may be longer than the feed wiring 161.

  Note that the second pattern wiring 160 may be covered with an insulating film such as a white resist or a glass film in the same manner as the first pattern wiring 150 for the purpose of protecting the wiring. The pattern wiring 160 is preferably exposed.

[Case]
As shown in FIGS. 1 to 3, the housing 200 is an outer housing that forms an outer shell of the lighting fixture 2, and houses the LED module 100. The housing 200 includes a first housing 210 having a light shielding property that covers a plurality of circuit elements 140 (power supply units), and a second housing 220 having a light transmitting property that covers the plurality of light emitting elements 120. . In the present embodiment, the first casing 210 and the second casing 220 are integrally formed by two-color molding, but the present invention is not limited to this. For example, the 1st housing | casing 210 and the 2nd housing | casing 220 are produced separately, and these may be fixed mutually with a latching structure, an adhesive agent, a screw | thread etc.

  The first housing 210 is a support member (base) that supports the LED module 100 (substrate 110). The first housing 210 is made of a white insulating resin material. Therefore, the first housing 210 has light reflectivity with respect to visible light. That is, the first housing 210 is shielded by reflecting light. In the present embodiment, the first housing 210 is made of white polycarbonate. Note that the first housing 210 may be made of a metal material such as aluminum or iron instead of the resin material. Further, the material of the first housing 210 is not limited to light shielding by reflecting light, but may be light shielding by absorbing light. In this case, for example, the first housing 210 may be made of a black insulating resin material.

  The first casing 210 has a first groove portion 211 into which one end portion in the width direction (X-axis direction) of the substrate 110 is inserted, and a first groove portion into which the other end portion in the width direction of the substrate 110 is inserted. 2 grooves 212. The first groove portion 211 and the second groove portion 212 function as guide rails (slide rails) when the substrate 110 is slid in the housing 200 and extend in the longitudinal direction of the housing 200. Thus, the light emitting element 120 and the circuit element 140 are mounted on the substrate 110 to form a module, and both end portions of the modularized substrate 110 are inserted into the first groove portion 211 and the second groove portion 212, so that the substrate 110 is attached to the housing 200. The LED module 100 can be housed in the housing 200 by sliding along the longitudinal direction and pushing it back.

  The first housing 210 is provided with a partition plate 213. The partition plate 213 partitions the plurality of light emitting elements 120 (light emitting unit) and the plurality of circuit elements 140 (power supply unit), and in a top view, the plurality of light emitting element 120 columns and the plurality of circuit element 140 columns. , And extends along the longitudinal direction of the substrate 110. In this manner, by providing the partition plate 213, the light emitted from the light emitting element 120 proceeds toward the partition plate 213 even when the plurality of light emitting element 120 columns and the plurality of circuit element 140 columns are arranged in parallel. The light to be blocked is uniformly shielded by the partition plate 213. Accordingly, it is possible to avoid that the line-shaped illumination light emitted from the plurality of light-emitting elements 120 is partially blocked by the circuit element 140 and a part of the line-shaped illumination light is lost and a shadow is formed, and the lighting fixture 2 ( It can suppress that the light distribution characteristic of the illuminating device 1) deteriorates. For example, the illuminating device 1 which irradiates uniform linear illumination light can be obtained. Furthermore, the strength of the housing 200 can be improved by providing the partition plate 213.

  The second housing 220 is a translucent cover that transmits light emitted from the light emitting element 120. The 2nd housing | casing 220 is comprised by translucent materials, such as translucent resin materials or glass materials, such as an acryl or a polycarbonate, for example.

  The second housing 220 may further have a light diffusing property (light scattering property). By providing the second casing 220 with light diffusibility, light from the light emitting element 120 that is a highly directional LED light source can be scattered. (Luminance unevenness) can be suppressed.

  When the second casing 220 is provided with light diffusibility, a second casing 220 is manufactured by dispersing a light diffusing material such as light reflecting fine particles in a translucent resin material, or a second casing made of a transparent member. By forming a milky white light diffusing film including a light diffusing material or the like on the surface (inner surface or outer surface) of 220, the second housing 220 can be provided with light diffusibility. Alternatively, instead of using a light diffusing material, fine irregularities are formed on the surface of the second housing 220 made of a transparent member by applying a texture or the like, or dots are formed on the surface of the second housing 220 made of a transparent member. The second casing 220 may be given light diffusibility by printing a pattern.

  In the present embodiment, the second housing 220 is a light transmissive cover (diffusion cover) made of polycarbonate and having light diffusibility. Note that the second housing 220 may be configured to control the light distribution of the light emitting element 120. For example, the second housing 220 may have a condensing function or a diverging lens function.

  The upper surface of the second housing 220 is substantially flush with the upper surface of the first housing 210. That is, the upper surface of the second housing 220 and the outer surface of the first housing 210 are flush with each other, and the upper surface of the second housing 220 and the upper surface of the first housing 210 are a continuous surface without a step. . In the present embodiment, the second housing 220 has an L-shaped cross section, but is not limited thereto.

[End cover]
As shown in FIGS. 1 and 2, the end cover (end cover) 300 is an end cap that covers an end portion of the casing 200 in the longitudinal direction. The end cover 300 is attached to each of both ends in the longitudinal direction of the housing 200.

  Of the two end covers 300, at least the end cover 300 on the first connection terminal 131 side is provided with an insertion hole through which the electric wire 400 is inserted. The electric wire 400 is inserted from the outside of the housing 200 through the insertion hole of the end cover 300 and connected to the first connection terminal 131.

  In the present embodiment, a pair of insertion holes is provided in both of the two end covers 300. That is, not only the end cover 300 on the first connection terminal 132 side but also the end cover 300 on the second connection terminal 131 side is provided with an insertion hole.

  Thereby, the electric wire 410 is inserted into the insertion hole of the end cover 300 on the second connection terminal 132 side and the electric wire 410 is connected to the second connection terminal 132, whereby the electric wire 410 is used as the power supply line and the first connection terminal. The AC power supplied from 131 can be output from the second connection terminal 132 via the electric wire 410. That is, when connecting the some illuminating device 1, AC electric power can be supplied to the adjacent illuminating device 1 using the electric wire 410 connected to the 2nd connection terminal 132. FIG.

  The end cover 300 is fixed to the housing 200 with, for example, an adhesive, a screw, or a claw structure. The end cover 300 is a resin molded product made of a resin material such as polybutylene terephthalate, but may be made of a metal material.

[Example of use]
Next, the usage example of the illuminating device 1 which concerns on embodiment is demonstrated using FIG. FIG. 7 is a diagram illustrating a circuit configuration when two lighting devices 1 according to the embodiment are connected.

  As shown in FIG. 7, for example, when connecting the lighting device 1 a (first lighting device) and the lighting device 1 b (second lighting device), the lighting device 1 a and the lighting device 1 b are connected in the longitudinal direction of the lighting device 1. The lighting device 1a and the lighting device 1b are connected by an electric wire 410 so as to be adjacent to each other. The electric wire 410 connecting the two lighting devices 1a and 1b has one end connected to the second connection terminal 132 of the lighting device 1a and the other end connected to the first connection terminal 131 of the lighting device 1b. . The electric wire 410 is a VVF cable or the like, for example, like the electric wire 400.

  In the two lighting devices 1 a and 1 b connected in this way, AC power is supplied to the lighting device 1 a from an external power source such as a commercial power source by the electric wire 400 connected to the first connection terminal 131. Thereby, in the lighting device 1a, the AC power supplied to the first connection terminal 131 is supplied to the power supply circuit 140a by the first pattern wiring 150 and is converted into DC power by the power supply circuit 140a. The DC power generated by the power supply circuit 140a is supplied to the light emitting element 120, the light emitting element 120 emits light, and the illumination light is irradiated from the lighting device 1a.

  Further, the AC power supplied to the first connection terminal 131 of the lighting device 1a is transmitted to the second connection terminal 132 by the feed wiring 161 of the lighting device 1a, and the adjacent lighting is connected from the second connection terminal 132 through the electric wire 410. It is supplied to the device 1b. The AC power supplied to the lighting device 1b is input to the first connection terminal 131 of the lighting device 1b and supplied to the power supply circuit 140a. Thereby, like the illuminating device 1a, also in the illuminating device 1b, the light emitting element 120 light-emits and illumination light is irradiated from the illuminating device 1b.

  Thus, when alternating current power is supplied to the illuminating device 1a, illumination light is irradiated from the illuminating device 1a and illumination light is also irradiated from the illuminating device 1b. Thereby, the line-shaped illumination light of about twice the length of the line-shaped illumination light irradiated by one illumination device 1 is irradiated.

[Effects]
As described above, in the LED module 100 according to the present embodiment, the distance between the first connection terminal 131 and the second connection terminal 132 is shorter than the length of the element row of the light emitting elements 120.

  With this configuration, the first connection terminal 131 or the second connection terminal 132 can be moved away from the longitudinal edge of the substrate 110, so that the first connection terminal 131 or the second connection terminal 132 and the longitudinal length of the substrate 110 are formed on the substrate 110. A space can be secured between the direction edge. That is, a space can be secured at the end in the longitudinal direction on the substrate 110.

  Thus, in consideration of assembly work efficiency, even if the electric wire 400 connected to the first connection terminal 131 or the electric wire 410 connected to the second connection terminal 132 is lengthened, the space at the end on the substrate 110 is used. Thus, the electric wire 400 or 410 can be accommodated. As a result, even when the end portion of the substrate 110 and the end portion of the housing 200 are close to each other, the electric wire 400 or the electric wire 410 can be prevented from being bent.

  Thus, according to the LED module 100 in the present embodiment, it is possible to suppress the bending of the electric wire 400 or 410 connected to the first connection terminal 131 or the second connection terminal 132 without reducing the assembly work efficiency. Can do.

  Therefore, the electric wire 400 or 410 is bent to generate a force for peeling the first connection terminal 131 or the second connection terminal 132 from the substrate 110, and the connection failure between the first connection terminal 131 or the second connection terminal 132 and the substrate 110 is generated. Can be suppressed, and it can be suppressed that the light emitted from the light emitting element 120 is shaded by the bending of the electric wire 400 or 410 and the light distribution characteristic is deteriorated.

  Further, in the LED module 100 according to the present embodiment, the light emitting element 120 at one end of the element row of the light emitting element 120 is located outward from the first connection terminal 131, and is at the other end of the element row of the light emitting element 120. The light emitting element 120 is located outside the second connection terminal 132.

  With this configuration, a space can be secured at both ends of the substrate 110 in the longitudinal direction. Therefore, when the wire 400 is connected to the first connection terminal 131 and the wire 400 is connected to the second connection terminal 132 (that is, the first connection terminal 131). Even when the electric wires are connected to both the first connection terminal 131 and the second connection terminal 132), it is possible to suppress the occurrence of bending of both the electric wires 400 and 410.

  In the LED module 100 according to the present embodiment, the plurality of circuit elements 140 are disposed between the first connection terminal 131 and the second connection terminal 132.

  Thereby, even if it is the elongate board | substrate 110 with which the several circuit element 140 which comprises the power supply circuit 140a was mounted, the aspect ratio of the board | substrate 110 can be enlarged and a linear light source can be implement | achieved easily.

  Further, in the LED module 100 according to the present embodiment, the plurality of light emitting elements 120, the plurality of circuit elements 140, the first connection terminals 131, and the second connection terminals 132 are arranged on the first surface 110a of the substrate 110 and are sent. The wiring 161 is formed on the second surface 110 b of the substrate 110.

  With this configuration, the aspect ratio of the substrate 110 is increased not only in the case where the plurality of circuit elements 140 constituting the power supply circuit 140a are mounted but also in the long substrate 110 in which the feed wiring 161 is formed. A thin line-shaped light source can be easily realized.

  Further, in the LED module 100 according to the present embodiment, intermediate wiring 163 extending along the longitudinal direction of the substrate 110 between the element back wiring 162 and the feed wiring 161 is formed on the second surface 110b of the substrate 110. Is formed.

  With this configuration, heat generated in the light emitting element 120 and the circuit element 140 can be efficiently radiated from the second surface 110b (back surface) of the substrate 110.

  Further, in the LED module 100 according to the present embodiment, the substrate 110 has a shape having a notch portion 111 in which a corner portion of a rectangular substrate is notched. Specifically, the notch 111 is formed in a portion corresponding to both of the two corners on the long side of the rectangular substrate.

  With this configuration, the wire 400 or the wire 410 can be easily routed, such as the wire 400 connected to the first connection terminal 131 or the wire 410 connected to the second connection terminal 132 can be routed to the second surface 110b of the substrate 110. Can be done. Thereby, the bending of the electric wire 400 or 410 can be suppressed further.

(Modification)
Next, an LED module 100A according to a modification will be described with reference to FIGS. FIG. 8A is a plan view of an LED module 100A according to a modification, and FIG. 8B is a rear view of the LED module 100A. FIG. 9A is a diagram showing the shape of the first pattern wiring 150A formed on the first surface 110a of the substrate 110 of the LED module 100A, and FIG. 5B is the first pattern wiring 150A. FIG. 6 is a diagram showing a land (opening 171 of the insulating film 170).

  The LED module 100A according to this modification is used as a light source of a lighting device (lighting fixture) as in the above embodiment. Similar to the LED module 100 in the above embodiment, the LED module 100 </ b> A in the present modification includes the substrate 110, the plurality of light emitting elements 120, the first connection terminal 131 and the second connection terminal 132, and the plurality of circuit elements 140. And a first pattern wiring 150A and a second pattern wiring 160A.

  In the present modification, the first connection terminal 151 is arranged such that the straight wiring portion of the first connection terminal wiring 151 in the first pattern wiring 150 protrudes from both sides of the first connection terminal 131 along the longitudinal direction of the substrate 110 in plan view. It overlaps 131.

  Specifically, the straight wiring portion of the first connection terminal wiring 151 in the first pattern wiring 150 is formed as two protruding portions protruding from both sides of the first connecting terminal 131, and the outside protruding portion 151 a protruding outside and the inside. A protruding inner portion 151b is provided.

  In the present modification, a third connection terminal 133 is further disposed on the first surface 110 a of the substrate 110. The third connection terminal 133 is arranged side by side with the first connection terminal 131. The third connection terminal 133 is arranged at a position that overlaps the outer protrusion 151a in the straight wiring portion of the first connection terminal wiring 151 in plan view. That is, the third connection terminal 133 is disposed outside the first connection terminal 131, and the first connection terminal 131 is closer to the second connection terminal 132 (inside) than the third connection terminal 133. Are arranged as follows.

  The third connection terminal 133 is a fast connection terminal, like the first connection terminal 131 and the second connection terminal 132. In the present embodiment, the wire insertion hole of the first connection terminal 131 and the wire insertion hole of the third connection terminal 133 are facing away from each other. Specifically, the wire insertion hole of the first connection terminal 131 faces the second connection terminal 132 (inner side), and the third connection terminal 133 is opposite to the second connection terminal 132 ( It faces the outside.

  The third connection terminal 133 is at the same potential as the first connection terminal 131. That is, when connecting the electric wire 400 to the LED module 100A, it is only necessary to select one of the first connection terminal 131 and the third connection terminal 133 to connect the electric wire 400. For example, when the electric wire 400 is connected to the first connection terminal 131, the third connection terminal 133 is a dummy terminal that is not used. In addition, you may apply the 3rd connection terminal 133 to the LED module 100 in the said embodiment.

  In the present modification, the second pattern wiring 160 has two projecting portions 164 that project from the intermediate wiring 163 to one side of the element row of the light emitting elements 120 (circuit element 140 side) in plan view. . The two protrusions 164 sandwich the feed wiring 161. In this modification, the two protrusions 164 are connected to both ends in the longitudinal direction of the intermediate wiring 163 and are formed to protrude from both ends of the intermediate wiring 163. The shape of each of the two protrusions 164 is, for example, a rectangular shape.

  In the present modification, the feed wiring 161 extends toward the end of the substrate 110 rather than the feed wiring 161 in the above embodiment. Specifically, the end of the feed wiring 161 on the first connection terminal 131 side is present at a position beyond the first connection terminal 131 and is present up to the position of the third connection terminal 133.

  In the LED module 100A according to this modification configured as described above, the distance between the first connection terminal 131 and the second connection terminal 132 is the length of the element row of the light emitting elements 120, as in the LED module 100 in the above embodiment. It is shorter than that.

  Thereby, like LED module 100 in the above-mentioned embodiment, it is possible to suppress bending of electric wires 400 or 410 connected to first connection terminal 131 or second connection terminal 132 without reducing assembly work efficiency. it can.

  Further, according to the LED module 100 </ b> A in the present modification, the straight wiring portion of the first connection terminal wiring 151 in the first pattern wiring 150 is on both sides of the first connection terminal 131 along the longitudinal direction of the substrate 110 in plan view. It overlaps with the first connection terminal 131 so as to protrude from the first connection terminal 131. Specifically, the straight wiring portion of the first connection terminal wiring 151 includes an outer protruding portion 151a and an inner protruding portion 151b.

  With this configuration, the outer protruding portion 151a can be used as an inspection land. For example, by forming an opening 171 in a part of the insulating film 170 covering the outer protrusion 151a and exposing a part of the outer protrusion 151a, the exposed outer protrusion 151a can be used as an inspection land. Can do.

  In addition, the third connection terminal 133 and the first connection terminal wiring 151 may be connected to each other at the outer protruding portion 151a of the first connection terminal wiring 151 in the straight wiring portion. Thereby, the 3rd connection terminal 133 and the 1st connection terminal 131 can be used selectively.

  In this case, the first connection terminal 131 and the third connection terminal 133 may be fast connection terminals, and the first connection terminal 131 and the third connection terminal 133 may be arranged so that the wire insertion hole faces backward.

  Accordingly, even when the first connection terminal 131 and the third connection terminal 133 that are fast connection terminals are arranged along the longitudinal direction of the substrate 110, the first connection terminal 131 and the third connection terminal 133 are arranged. The electric wire 400 can be easily connected by selecting.

  Further, in the LED module 100A in the present modification, the second pattern wiring 160A has two projecting portions 164 projecting from the intermediate wiring 163 to one side of the element row of the light emitting element 120, and the two projecting portions 164 The part 164 sandwiches the feed wiring 161.

  With this configuration, an empty space on the second surface 110b of the substrate 110 generated by making the distance between the first connection terminal 131 and the second connection terminal 132 shorter than the length of the element row of the light emitting elements 120 is used. The protruding portion 164 can be formed as a heat dissipation wiring. Thereby, the heat generated in the light emitting element 120 and the circuit element 140 can be dissipated more efficiently.

(Other variations)

However, the present invention is not limited to this, and a plurality of LED modules 100 may be disposed in one housing 200. In this case, the plurality of LED modules 100 may be arranged so as to be adjacent along the longitudinal direction of the LED module 100 (longitudinal direction of the substrate 110), and the two adjacent LED modules 100 may be connected by the electric wire 400. Thereby, AC power can be sequentially transmitted to the adjacent LED module 100 by relaying each LED module 100. The same applies to the LED module 100A in the modification.

  Moreover, in the said embodiment, although the two illuminating devices 1 were connected, you may connect the 3 or more several illuminating devices 1. FIG. Thereby, like the aspect shown in FIG. 7, each illuminating device 1 can be relayed and alternating current power can be transmitted to the adjacent illuminating device 1 sequentially.

  Moreover, it is not restricted to connecting the illuminating devices 1 or LED modules 100. For example, you may connect the illuminating device 1 or the LED module 100, and another electronic device with an electric wire. Thereby, AC power can be supplied from the lighting device 1 or the LED module 100 to another electronic device by the feed wiring 161.

  In the above-described embodiment, the plurality of circuit elements 140 configure the power supply circuit 140a for causing the light emitting element 120 to emit light. However, the present invention is not limited to this, and other circuit circuits may be configured. That is, the LED module 100 may be configured such that the feed wiring 161 supplies AC power to a circuit other than the power supply circuit 140a. The same applies to the LED module 100A in the modification.

  Moreover, in the said embodiment, although the LED module 100 was a SMD type which used the SMD type LED element as the light emitting element 120, it is not restricted to this, A COB type may be sufficient. In this case, an LED chip (bare chip) may be used as the light emitting element 120, a plurality of LED chips may be arranged on the substrate 110, and the plurality of LED chips may be collectively sealed with a line-shaped sealing member. The same applies to the LED module 100A in the modification.
