Description

  The present invention relates to an illuminating device using a solid light emitting element, and more particularly to an illuminating device capable of suppressing unnecessary dismantling.

  Conventional light sources for illumination include incandescent bulbs (including halogen bulbs), fluorescent lamps, HID lamps (high-pressure sodium lamps, mercury lamps, metal halide lamps). Recently, light emitting diodes (LEDs) and organic EL light emitting devices (organic LEDs), which are solid state light emitting devices, have begun to be used as light sources for illumination. In particular, in the case of a light-emitting diode as a light source for illumination, as the light emission efficiency increases, an illumination device having a light bulb alternative shape, an illumination device imitating a fluorescent lamp illumination device, and the like are being studied.

  Solid-state light emitting devices have low energy consumption, and it is predicted that the rate of use as light sources for illumination will increase dramatically in the future. If it does so, while the illuminating device using a solid light emitting element will be used in large quantities, the illuminating device using the solid light emitting element after the period of use will be discarded in large quantities. Under such circumstances, it is necessary to collect the solid light-emitting elements incorporated in the lighting device and to recycle resources.

  Gallium-based semiconductors such as GaAs and GaP are used for light emitting diodes. Here, the state of gallium recycling in the communication electronic device (for example, mobile phone) industry where gallium semiconductors are actively used will be described. In the electronic device industry for communications, about 60 to 70% of gallium is recovered for the scrap generated in the manufacturing process. However, gallium is recovered because the recycling process is complicated for product scrap. The ratio is small. This example of a communication electronic device shows that it is necessary to promote recycling from product scrap. In order to facilitate recycling from product scrap, it is desirable to first produce an electrical product that can be easily disassembled.

  The following Patent Documents 1 to 4 describe technologies for facilitating disassembly of electrical products and their components in consideration of recycling. In the following Patent Documents 1 and 2, dismantling is facilitated by a method of utilizing an engaging claw and reducing the number of screws used. In the following Patent Documents 3 and 4, disassembly is facilitated by incorporating a mechanism for breaking the casing inside the casing, or by joining dissimilar materials (metal and resin, etc.) with a material that becomes brittle by hydrogen. Yes. According to such a technique, it is considered that the electric product can be easily disassembled and the target component can be easily taken out.

  Patent Document 5 below relates to a fastener that joins two casings, and when the coupling of the casings is released, the fasteners are destroyed and remain in the casing, leaving a trace of the casing being opened. It is described.

Hiroshi Minami “Rare Metals 2007 (6) Demand, Supply, Price Trends of Strontium and Gallium” Metal Resources Report 2008

  Solid light-emitting elements have the advantage that they have a longer lifetime than illumination light sources such as fluorescent lamps that have been widely used in the past, in addition to low energy consumption, including their future possibilities. Although organic EL light-emitting devices still have problems in terms of light output and short lifetime of light flux degradation, the lifetime as a light source for illumination is expected to be greatly extended in the future. Yes.

  Thus, since the lifetime of the solid state light emitting device used for the lighting device is very long or will be long in the future, basically, the lighting device designed with the policy that the lighting light source incorporated in the lighting device is never exchanged. Is likely to increase. That is, it is not necessary to replace the illumination light source of the illumination device, and it is not necessary to design the illumination device so that the illumination light source can be easily removed from the illumination device. Furthermore, from the viewpoint of the operational reliability and safety of the product, it is desirable to dismantle the illumination device unnecessarily so that the illumination light source cannot be taken out from the illumination device.

  However, as described above, assuming that a large number of solid state light emitting devices will be shipped for illumination in the future, it is expected that it will be essential to easily collect the solid state light emitting devices from product scrap in the future. . Although the recycling of the organic EL light emitting device was not mentioned, it is expected that the necessity of decomposing the organic material or recovering the inorganic material similarly occurs.

  However, when the illumination light source cannot be easily removed from the illumination device, it takes time to take out the illumination light source from the illumination device products collected from the market, which hinders recycling. It is also conceivable to crush the entire lighting device product and extract gallium from the crushed material or decompose the organic EL compound, but this is not practical because the cost required for recycling increases. Moreover, it is desirable to efficiently recycle not only the illumination light source but also the resin member, metal member, and the like constituting the housing.

  Therefore, in order to efficiently recycle, it is desirable that the lighting device can be easily disassembled and the illumination light source can be easily removed from the lighting device. Therefore, it is predicted that the number of lighting devices that are easy to disassemble in consideration of recyclability will increase by using the techniques described in Patent Documents 1 to 4 above. However, from the viewpoint of the operational reliability described above, it is desirable to suppress unnecessary dismantling acts such as dismantling the lighting device for purposes other than recycling. In particular, it is desirable to suppress removal of the illumination light source.

In Patent Documents 1 to 4 described above, a technique for facilitating dismantling is described, but it is not described that an unnecessary dismantling act is suppressed. The fastener described in Patent Document 5 has an effect of suppressing unauthorized disassembly if there is regular monitoring by a third party, but an effect of suppressing unnecessary disassembly with respect to the lighting device cannot be expected.
An object of this invention is to obtain the illuminating device which can suppress unnecessary dismantling, such as dismantling an illuminating device for the objectives other than recycling in view of an above-described subject.

  In order to achieve the above object, an illumination device according to the present invention includes a housing that is an assembly of a plurality of constituent members, and a light emitting element that is attached to the constituent members included in the housing, and includes a solid-state light emitting element. When the module and the light emitting module are attached, the light emitting module is coupled to the component member, or two of the plurality of component members are coupled in the assembly of the plurality of component members, and the coupling release operation is performed. And a power to be supplied to the solid-state light emitting element by interlocking with a releasing operation of the coupler accompanying a coupling releasing operation by being mechanically linked with the coupler. And a feeding path cutting mechanism for cutting the feeding path.

  In the lighting device according to the present invention, since the power supply path is cut in conjunction with the uncoupling operation and the light emitting module does not light, unnecessary dismantling acts such as dismantling the lighting device for purposes other than recycling are effectively performed. Can be deterred. Even if the lighting device cannot be turned on, there is no problem because the object to be recycled is a discarded lighting device. The unlit state includes a state where the illuminance is remarkably lowered in addition to a state where the light is not lighted at all. It should be noted that it is desirable to attach a cautionary note or the like indicating that the lighting device will not light up when disassembled.

For example, the coupling tool can be easily released by a connection release operation like a screw member. For example, even if it has an engaging claw etc., it should just be able to cancel combination by some release operation. For example, even if it is a rivet shape, a connection can be released by breaking a fragile part.
In the above configuration, a coupler (referred to as a specific coupler) that is mechanically linked to the feed path cutting mechanism is one of the invention-specific matters, and other couplers (referred to as general couplers). There is no limitation. However, the general coupler is not not used, and any general coupler can be used for assembling a plurality of constituent members included in the casing and attaching the light emitting module to the casing. The general coupler is preferably one that can be easily released by a release operation. And when a coupling release operation is performed on some of the plurality of couplers, unnecessary disassembly can be suppressed even when the power supply path is cut and the lighting device cannot be turned on. It is.

  The coupling release operation is, for example, an operation of rotating the screw member, an operation of pulling out the coupling pin, or the like. The power supply path includes wiring for supplying power to the light emitting module. In addition, when an electronic circuit component for lighting the light emitting module is provided in the lighting device, the electronic circuit component is also included in the power feeding path. Note that the feeding path can also be referred to as a conductive path. Examples of the solid light emitting element include a light emitting diode (LED), an organic EL light emitting element (organic LED), and a semiconductor laser diode (LD).

(1) Further, in the lighting device according to the present invention, an operation unit in which the power supply path cutting mechanism is operated by the coupler at the time of a coupling release operation, and a component constituting the operation unit and a part of the power supply path And a connecting part that cuts off the power feeding path by removing the component in conjunction with the operation of the operating part.
According to the above configuration, the power feeding path can be disconnected in conjunction with the coupling release operation performed on the coupler. The operation of the operation unit is, for example, an operation that rotates together with the screw member or an operation that moves in the axial direction together with the coupling pin. In addition, the operating part can be engaged with or joined to the coupler. The parts constituting a part of the power supply path can be, for example, conductive terminals, electronic circuit parts, wiring members, and the like. In addition, when removing those components, it is not essential that the electrical connection between these components and the power supply path is interrupted even at one place, and the light emitting module cannot be turned on.

(2) Further, in the lighting device according to the present invention, the housing includes a base that supports the light emitting module as one of the plurality of constituent members, and the power supply path cutting mechanism includes the base and An interposed plate portion interposed between the light emitting module and an elastic member that urges the interposed plate portion to bend toward the light emitting module side;
The interposed plate portion includes a first plate-like member to which a first portion on one end side of the light-emitting module is fixed, and a second plate-like member to which a second portion on the other end side of the light-emitting module is fixed. And a connecting member that rotatably connects the first member and the second member,
The first plate-like member is coupled to the base by the coupling tool together with the first part of the light emitting module in a state where the elastic member is engaged and elastically deformed with the elastic member.
When the coupling release operation is performed in a state where the second plate-shaped member and the second portion of the light emitting module are fixed to the base, the first plate-shaped member is moved to the base by the restoring force of the elastic member. The light emitting module is turned in a direction away from the base, and the light emitting module is bent and broken to cut the power supply path in the light emitting module.

  According to the said structure, when a light emitting module is removed, unnecessary removal can be suppressed by destroying a light emitting module.

An LED module 11 is attached to the front side of the support plate 23 as a base, and a lighting circuit 13 is attached to the back side. The support plate 23 is made of a material having good thermal conductivity (for example, an aluminum alloy), and also functions as a radiator of the LED module 11.
The case body 21 includes a housing part 31 that houses the lighting circuit 13 and a frame 33 that extends from the opening end of the housing part 31. A support plate 23 is coupled to the inner peripheral portion of the frame 33 by a screw member 34. A screw hole 35 is formed in the outer peripheral portion of the frame 33 in the arrangement direction of the plurality of LED modules 11.

The cover member 25 is made of a translucent material such as a translucent resin or glass, and transmits the output light of the LED module 11 to the front side. In addition, the outer surface of the cover member 25 is subjected to a satin treatment, so that the output light of the LED module 11 is diffused by the cover member 25 and a light distribution pattern close to an incandescent bulb can be obtained.
In the arrangement direction of the plurality of LED modules 11, through holes 41 and 42 are provided at both ends of the cover member 25 at positions corresponding to the screw holes 35. The cover member 25 is coupled to the frame body 33 by screw members 45 and 46 that are coupling tools inserted into the through holes 41 and 42.

The left screw member 46 in FIG. 1 is engaged with a one-way clutch 48. The one-way clutch 48 will be described later. A recess 49 is formed in the frame 33 at a location where the one-way clutch 48 is disposed.
(About LED module)

The substrate 51 has a metal layer formed of aluminum or the like, and an insulating layer (for example, made of resin) laminated thereon. A plurality of LED elements 55 are connected to the wiring pattern formed on the substrate 51 in the LED mounting portion 53. In addition, connection terminals 58 connected to a part of the wiring pattern 57 formed by plating are formed on the substrate 51.

Although not shown, a resin layer in which a phosphor having a wavelength conversion function for converting the wavelength of light emitted from the LED element 55 is encapsulated is formed on the LED element 55. The presence of the resin layer encapsulating the phosphor makes the light emitted from the LED module 11 white.
(About lighting circuit)
The lighting circuit 13 includes an AC / DC converter 61 that converts AC power supplied from a commercial power source into DC power, and a voltage controller 63 that adjusts the voltage of the DC power obtained by the AC / DC converter 61. including.

  The AC / DC converter 61 is connected to a power cable 65 inserted into the case 15 from the outside, and is supplied with commercial AC power. The AC / DC converter 61 is connected to two lead wires 67a and 67b that output DC power. One lead wire 67 a is connected to the voltage control unit 63, and the other lead wire 67 b is connected to the power supply path cutting mechanism 17. Further, the power supply path cutting mechanism 17 and the voltage control unit 63 are connected by a lead wire 67c. That is, the AC / DC conversion unit 61 and the voltage control unit 63 are connected via the power supply path cutting mechanism 17.

  The DC power adjusted to an appropriate voltage by the voltage control unit 63 is supplied to the LED module 11 through the two lead wires 71a and 71b. The two lead wires 71a and 71b pass through the wiring holes 73 provided in the support plate 23 and are connected to the two wires disposed at both ends of the plurality of LED modules 11, respectively. Further, as shown in FIG. 2, the plurality of LED modules 11 are connected in parallel by lead wires 75a and 75b.

With the connection as described above, a power supply path including a power cable, a lead wire, a lighting circuit 13, wiring in the LED module 11, and the like is formed. Direct current power of a predetermined voltage is supplied from the lighting circuit 13 to the plurality of LED modules 11, and the plurality of LED modules 11 emit light. The power cable and the lead wire are a kind of wiring member.
(About feed line cutting mechanism)
FIG. 4 shows a cross-sectional view of the feed path cutting mechanism 17. The feeding path cutting mechanism 17 includes a cutting target portion 101 that is a portion to be cut in the feeding path, a one-way clutch 48 engaged with the screw member 46, a one-way clutch 48, and a cutting target portion 101. And a string member 105 (connecting portion).

(About the cutting target part)
FIG. 5 shows a cross section of the cutting target portion 101. The cutting target part 101 includes two conductive pieces 111, conductive pins 113 that connect them, and a container 115 that stores the conductive pieces 111 and the conductive pins 113.
The conductive piece 111 serving as a terminal portion includes a ring-shaped portion 121 that is curved in a ring shape, and a terminal portion that extends to the outside of the container 115 and passes through the support plate 23 and is connected to one of the lead wires 67b and 67c. 123.

  The conductive pin 113 serving as the connection portion has a cylindrical shape, and is inserted into the ring-shaped portion 121 of the two conductive pieces 111 to electrically connect the two conductive pieces 111. That is, the two conductive pieces 111 and the conductive pins 113 are brought into conduction by contact, and the conductive pins 113 are easily removed. Further, the diameter of the center of the conductive pin 113 is slightly increased (slightly exaggerated), so that it cannot be easily removed from the ring-shaped portion 121. A groove 125 is formed at the end of the conductive pin 113 on the one-way clutch 48 side, and the end of the string member 105 is bonded to the groove 125 (FIG. 4).

  The container 115 has a rectangular parallelepiped shape extending in the axial direction of the conductive pin 113 and is coupled to the support plate 23. A slit 131 through which the string member 105 is passed is formed on the one-way clutch 48 side of the container 115. Further, a detaching pin accommodating portion 133 that accommodates the conductive pin 113 removed from the two conductive pieces 111 is formed on the one-way clutch 48 side of the two conductive pieces 111 (FIG. 4).

The two conductive pieces 111, the container 115, and the support plate 23 are electrically insulated by an insulating material such as a resin material or enamel paint.
In addition, it is preferable that the adjacent two conductive pieces 111 have a spatial distance of 1.5 mm or more in consideration of insulation.
(About one-way clutch)
FIG. 6 shows an exploded perspective view of the one-way clutch 48 which is an operation part. FIG. 7 shows a cross section of the one-way clutch 48.

The one-way clutch 48 includes an impeller-shaped inner peripheral rotor 141 and a cylindrical outer peripheral rotor 143 disposed on the outer periphery of the inner peripheral rotor 141.
The inner circumferential rotor 141 is fixed to the shaft portion 145 of the screw member 46 and is rotated integrally with the screw member 46. The inner circumferential rotor 141 has a plurality of blade portions 147 provided to be inclined in the circumferential direction with respect to the diameter direction of a circle centered on the axis of the screw member 46.

The outer peripheral rotor 143 is inserted into the through hole 42, and the front side flange-like portion is engaged with the cover member 25, thereby preventing movement in the frame 33 direction. In addition, a plurality of protrusions 149 are formed on the inner peripheral portion of the outer peripheral rotor 143 in the axial direction of the screw member 46.
The plurality of blade portions 147 and the plurality of protrusions 149 are engaged at the time of relative rotation in one direction. The wing | blade part 147 has flexibility, for example, is formed with hard rubber, resin etc. which are easy to elastically deform. Therefore, when the inner peripheral rotor 141 is rotated clockwise, the blade portion 147 bends to the inner peripheral side to a position where it does not interfere with the protrusion 149, and the inner peripheral rotor 141 and the outer peripheral rotor 143 rotate relative to each other. be able to. On the contrary, when the inner peripheral rotor 141 is rotated counterclockwise, the blade portion 147 is turned upside down by the protrusion 149, and relative rotation between the inner peripheral rotor 141 and the outer peripheral rotor 143 is prevented.

Thus, relative rotation of the inner circumferential rotor 141 and the outer circumferential rotor 143 is allowed only in the tightening direction of the screw member 46 (only in one direction). In addition, it is not necessary to strictly prevent the relative rotation in the removing direction of the screw member 46, and the relative rotation may be performed to some extent (the rotation angle is within several tens of degrees or the like).
The outer peripheral rotor 143 is inserted into the through hole 42 of the cover member 25 so as to be rotatable in one direction. An engagement groove 151 is extended in the axial direction on the outer peripheral wall of the outer peripheral rotor 143. When the outer peripheral rotor 143 is rotated clockwise, the engagement groove 151 is provided on the inner peripheral portion of the through hole 42. The tip of the piece 153 and the engaging groove 151 are brought into contact with each other to be locked. On the other hand, when the outer peripheral rotor 143 is rotated counterclockwise, the locking piece 153 bends and retracts into the recess 154, thereby allowing the outer peripheral rotor 143 to rotate. That is, the outer peripheral rotor 143 is allowed to rotate only in the direction in which the screw member 46 is removed.

With the above structure, in the one-way clutch 48, the outer peripheral rotor 143 is not rotated when the screw member 46 is tightened, but is rotated when the screw member 46 is removed.
A pin 155 extending in the axial direction is provided at the tip of the outer peripheral rotor 143. The pin 155 is tied to the end of the string member 105 that is a connecting portion. Therefore, when the outer peripheral rotor 143 is rotated, the string member 105 is wound up by the pin 155 and the shaft portion 145.

<Operation>
(About unbinding)
The operation | movement at the time of the disassembly of the illuminating device 1 in this embodiment is demonstrated.
When the lighting device 1 is disassembled, the screw members 45 and 46 are sequentially rotated in the coupling release direction by a driver or the like (coupling release operation), and moved from the coupling position to the coupling release position. The order in which the four screw members 45 and 46 are removed is arbitrary.

  When the screw member 46 to which the one-way clutch 48 is attached is rotated in the coupling release direction, the inner peripheral rotor 141 and the outer peripheral rotor 143 are engaged, and the outer peripheral rotor 143 is rotated together with the screw member 46. When the string member 105 is wound by the pin 155 and the shaft portion 145, the conductive pin 113 connected to one end of the string member 105 is pulled toward the one-way clutch 48, and the conductive pin 113 becomes the conductive piece 111. (See FIG. 8). That is, the conduction between the two conductive pieces 111 is cut off. The conductive pin 113 is accommodated in the separation pin accommodating portion 133 so that it does not come out of the container 115.

The outer peripheral rotor 143 is continuously rotated, and the conductive pin 113 comes into contact with the wall surface on the one-way clutch 48 side of the container 115 and cannot move. Further, the bonding between the string member 105 and the conductive pin 113 is released, or the string member 105 is cut.
As described above, the power supply path is cut by the coupling release operation, and the DC power is not supplied from the AC / DC conversion unit 61 to the voltage control unit 63, so that the LED module 11 cannot be turned on. Further, even if the screw member 46 is rotated in the coupling direction and coupled again, the state where the conductive pin 113 is detached from the conductive piece 111 is maintained, and thus the LED module 11 does not light up.

As described above, the feed path cutting mechanism 17 is mechanically linked to the screw member 46 by the one-way clutch 48, and operates in conjunction with the rotation (release operation) of the screw member 505a in the coupling release direction. Therefore, the relative movement in the axial direction between the inner circumferential rotor 141 and the outer circumferential rotor 143 is allowed. Therefore, the screw member 46 enters the screw hole 35 while moving relative to the outer peripheral rotor 143 at the time of coupling, and the screw member 46 comes out of the screw hole 35 at the time of releasing the coupling. The friction between the inner rotor 141 and the outer rotor 143 is increased when the coupling is released, and the outer rotor 143 may come out of the through hole 42 together with the screw member 46. There is no problem because it moves in the pulling direction.

(About assembly)
A method for assembling the lighting device 1 will be described.
The lighting circuit 13 and the cutting target portion 101 are attached to the support plate 23, and the lead wires 67 and 71, the power cable 65 and the like are connected to them by soldering or the like. Thereafter, the support plate 23 is coupled to the case 15, and the LED module 11 is attached to the front side of the support plate 23. Furthermore, the lead wires 71 and 75 are connected to a predetermined LED module 11.

At the time of assembly, the conductive pins 113 of the cutting target portion 101 are inserted into the two conductive pieces 111. Moreover, the string member 105 is made longer than the state of FIG.
Before attaching the cover member 25, the string member 105 is put out to the front side of the cover member 25 through the through hole 42. Then, the three screw members 45 are temporarily fixed.
As shown in FIG. 9, the string member 105 is tied to the pin 155 before the outer circumferential rotor 143 is inserted into the through hole 42. At this time, it is desirable to make the string member 105 short. The string member 105 may be bonded to the pin 155. The outer peripheral rotor 143 is inserted into the through hole 42 while the string member 105 is housed in the through hole 42. Thereafter, the screw member 46 is inserted into the inner periphery of the outer rotor 143 so that the blade portion 147 of the inner rotor 141 fitted on the shaft 141 does not interfere with the protrusion 149 of the outer rotor 143. Further, the tip of the shaft portion 141 is screwed into the screw hole 35 with care not to bite the string member 105. Thereafter, the screw member 46 is rotated about one turn in the coupling release direction to wind up the slack of the string member 105. In addition, you may let loosen without winding up.

Finally, the screw members 45 and 46 are tightened.
The screw member 46 and the outer peripheral rotor 143 can also be inserted into the through hole 42 in a state where the screw member 46 is inserted into the inner periphery of the outer peripheral rotor 143. The assembling method is suitable when the screw member 46 and the one-way clutch 48 are not relatively movable in the axial direction.
<Operational effects and others>
Since the case 15 is assembled by the coupling by the screw members 45 and 46, the lighting device 1 of the present embodiment can be easily disassembled when the case 15 is discarded.

On the other hand, when unnecessary disassembly is performed, the power supply path is cut by the power supply path cutting mechanism 17, and thus the LED module 11 cannot be turned on. Thereby, an unnecessary dismantling act can be suppressed. In addition, it is desirable to write a cautionary note or the like indicating that the lighting device or the instruction manual will not light when disassembled.
In the present embodiment, the power supply path formed in the cutting target portion 101 is cut, which is more preferable than simply cutting the lead wire 67 and the like. This is because when the unfixed lead wire 67 is cut, electricity may flow when the cut portion comes into contact with the conductive portion.

Since the illuminating device 1 of this embodiment employs the one-way clutch 48, when the screw member 46 is rotated in the coupling direction (clockwise), the outer peripheral rotor 143 does not rotate. Therefore, the conductive pin 113 does not come off during assembly, and assembly is easy.
In the present embodiment, the cutting target unit 101 is provided in the power supply path (between the lead wires 67b and 67c) that connects the AC / DC conversion unit 61 and the voltage control unit 63. It can also be provided. For example, the cutting target unit 101 can be provided in a power supply path that supplies AC power to the AC / DC conversion unit 61 by the power cable 65. In addition, for example, the cutting target unit 101 can be provided in a power supply path (lead wire 71) connecting the voltage control unit 63 and the LED module 11. It should be noted that it is desirable to provide the cutting target portion 101 in a portion where the power to be fed is smaller than the power supply cable 65, such as the feeding path (lead wire 67, lead wire 71).

In the present embodiment, the screw member 46 engaged with the one-way clutch 48 is a “specific coupler”, and the other screw members 45 and the like are “general couplers”.
<Modification>
The vane portion 147 of the one-way clutch 48 is relatively easily elastically deformed, but the inner circumferential rotor can be formed of a material that is difficult to elastically deform (for example, a relatively highly synthetic resin or the like). .

In FIG. 10, the cross section of the one way clutch 171 of this modification is shown.
The one-way clutch 171 includes a gear-shaped inner peripheral rotor 173 and a cylindrical outer peripheral rotor 174 disposed on the outer periphery of the inner peripheral rotor 173.
The inner rotor 173 is fixed to the shaft portion 145 of the screw member 46 and is rotated integrally with the screw member 46. The inner circumferential rotor 173 has a plurality of teeth 175 having an asymmetric shape in the circumferential direction. When the inner circumferential rotor 173 rotates clockwise, the tooth 175 has a smaller inclination of the tooth surface 177 in front of the tooth tip in the rotation direction and a larger inclination of the rear tooth surface 178 (in the radial direction). parallel). The inclination of the tooth surface increases as the angle formed between the radial direction of the tooth tip circle (or tooth root circle, etc.) of the inner circumferential rotor 173 and the tooth surface decreases.

  On the other hand, the outer peripheral rotor 174 is provided with a plurality of locking pieces 181 that engage with the teeth 175 of the inner peripheral rotor 173. The locking piece 181 extends from the outer peripheral rotor 174 to the inner peripheral side along the generally front tooth surface 177. When the inner circumferential rotor 173 is rotated counterclockwise (in the coupling release direction), the inner circumferential rotor 173 contacts the tooth surface 178 and prevents relative rotation between the inner circumferential rotor 173 and the outer circumferential rotor 174. On the other hand, when the inner circumferential rotor 173 is rotated clockwise (in the coupling direction), the locking piece 181 is bent by the tooth surface 177 and retracted into the recess 179, so that the inner circumferential rotor 173 and the outer circumferential rotor 173 are rotated. Relative rotation with the rotor 174 is allowed.

The one-way clutch 171 can also allow relative rotation between the inner peripheral rotor 173 and the outer peripheral rotor 174 only in the tightening direction of the screw member 46 (only in one direction). In addition, since the inner rotor 173 is difficult to deform, it can cope with a large torque.
The outer peripheral rotor 174 is formed with an engaging groove 151 similar to the outer peripheral rotor 143, and is not rotated when the screw member 46 is tightened by engagement with the locking piece 153, but is rotated when removed. It is supposed to be.

In the present modification and the first embodiment, the engagement groove 151 and the locking piece 153 are not essential components. For example, if the conductive pin 113 is not pulled out of the conductive piece 111 by the string member 105 when the screw member 46 is tightened, the engagement groove 151, the locking piece 153, and the like can be omitted.
[Embodiment 2]
In the first embodiment, the wiring is cut as the power feeding path. However, the power feeding path can also be cut by removing a circuit component as a component constituting a part of the power feeding path.

11 and 12 are a plan view and a side sectional view of the lighting device 201. FIG.
In addition, since the illuminating device 201 of a present Example has many parts which are common in the illuminating device 1 of the said Embodiment 1, the same code | symbol as Embodiment 1 is attached | subjected to the same component and description is abbreviate | omitted. In addition, although the shape and dimension differ in the component which attached | subjected the same code | symbol as Embodiment 1, the component with the same function is also contained. The illuminated surface side of the illumination device 201 is referred to as “front side”, and the opposite side is referred to as “back side”.

<Configuration>
As shown in FIG. 13, in the lighting device 201, an electronic circuit component is provided in each of the four LED modules 211. The string member 105 of the feed path cutting mechanism 217 is connected to the electronic circuit component. Then, when the screw member 46 is rotated counterclockwise by the coupling release operation, the electronic circuit components constituting a part of the power supply path are removed, the power supply path is cut, and the LED module 211 is not lit.

In the present embodiment, two power supply path cutting mechanisms 217 are provided. Each power supply path cutting mechanism 217 is not provided with the cutting target portion 101 and is provided with a one-way clutch 48 and a string member 105. The one-way clutch 48 is connected to two string members 105a and 105b bonded to electronic circuit components of the two LED modules 211.
Although the lighting circuit 13 is the same as that of the first embodiment, in FIG. 12, the AC / DC conversion unit 61 is located on the back side of the voltage control unit 63, and is not illustrated.

(Installation of LED module)
FIG. 13 shows a state where the LED module 211 is attached to the support plate 23.
In the LED module 211, the peripheral edge of the substrate 51 is fixed by a plurality of pressing members 221. Further, the pressing member 221 is coupled to the support plate 23 by a screw member 223.

The pressing member 221 includes a flat plate portion 231 fixed by the screw member 223 and an “inverted L-shaped portion 233” standing on the end portion of the flat plate portion 231. The inverted L-shaped portion 233 fixes the LED module 211 by contacting the side surface and the top surface (the main surface on which the LED element 55 is provided) of the substrate 51.
In the first embodiment as well, the LED module 11 can be attached using the pressing member 221 and the screw member 223 which are engaging tools.

(LED module)
The LED module 211 includes the same substrate 51, LED mounting portion 53, LED element 55, and connection terminal 58 as the LED module 11 of the first embodiment. The LED module 211 is provided with a constant current circuit portion 241 between the LED mounting portion 53 and the connection terminal 58. The constant current circuit unit 241 makes the current supplied to the plurality of LED elements 55 constant, and stabilizes the luminous intensity of the LED elements 55.

FIG. 14 shows a circuit diagram of the LED module 211.
The LED mounting portion 53 has a configuration in which a total of 64 LED elements 55 are arranged in 8 rows and 8 rows.
The constant current circuit unit 241 has a general constant current circuit composed of one resistance element 243 and two NPN transistor elements 244 and 245. Specifically, a resistance element 243 is inserted between the emitter and base of the transistor element 244, and the base of the transistor element 244 is connected to the emitter of another transistor element 245. The collector of the transistor element 244 is connected to the base of the transistor element 245.

The base of the transistor element 245 is connected to the connection terminal 58 a on the IN side and one terminal 251 of the LED mounting portion 53, and the collector is connected to the other terminal 253 of the LED mounting portion 53. The emitter of the transistor element 244 is connected to the connection terminal 58b on the OUT side.
In this way, the constant current circuit unit 241 is configured to be inserted into the power supply path in the LED module 211, and the constant current control is performed on the power supplied from the voltage control unit 63 to perform the constant current control. The supplied electric power is supplied to the LED mounting unit 53. That is, the constant current circuit unit 241 functions as a circuit for stabilizing the luminous intensity of the LED element 55 when the LED module 211 is driven to emit light.

An end portion of the string member 105 is bonded to the transistor element 245 of the constant current circuit portion 241.
<Operation>
The operation of the power supply path cutting mechanism 217 is the same as that of the power supply path cutting mechanism 17 of the first embodiment. That is, when the screw member 46 is rotated in the coupling release direction by the coupling release operation, the outer peripheral rotor 143 of the one-way clutch 48 is rotated to wind the string member 105. As a result, the transistor element 245 which is an electronic circuit component is removed from the constant current circuit, and the LED module 211 does not light up. That is, the power feeding path is cut.

  Two string members 105 are connected to one one-way clutch 48. Of the four LED modules 211, the string member 105a connected to the LED modules 211a arranged at both ends is less slack, and the string member 105b connected to the LED module 211b arranged in the center is loosened. ing. Therefore, at the time of the coupling release operation, after the transistor element 245 of the LED module 211a is detached, the transistor element 245 of the LED module 211b is detached. In this manner, by shifting the removal timing, the transistor element 245 can be removed with a relatively small force.

A description of the assembly method is omitted.
<Operational effects and others>
The lighting device 201 of the present embodiment can achieve the same effects as those of the first embodiment. In the present embodiment, since the LED module 211 itself cannot be used, it is possible to prevent a situation in which the LED module 211 whose life has been shortened is inappropriately used.

  Note that electronic circuit components that are to be removed by the power supply path cutting mechanism 217, that is, electronic circuit parts that are part of the power supply path, are disconnected from each other and the LED module 211 cannot be turned on. desirable. In addition, when the electronic circuit component that is a part of the power supply path is removed, the LED module 211 is turned on, but the illuminance may be significantly reduced.

Note that the modification of the first embodiment can be applied to the lighting device 201.
<Modification>
An adapter for attaching the transistor element 245 may be provided in the constant current circuit portion 241.
15 and 16 are a perspective view and a cross-sectional view of the adapter 261. FIG.

  The adapter 261 has a U shape in a sectional view, and the end portions of the upper wall portion 263 and the lower wall portion 264 are connected by the side wall portion 265. Then, the transistor element 245 can be sandwiched in a rectangular recess 267 surrounded by three walls. As shown in the figure, it is desirable that an elastic member such as rubber is interposed between the transistor element 245 and the upper wall portion 263 so that the transistor element 245 is firmly held by the adapter 261.

  The adapter 261 has a plurality of conductive terminals 269 attached to the lower wall portion 264. The conductive terminal 269 has a U shape and is attached so as to sandwich the lower wall portion 264 from above and below. The conductive terminal 269 is connected to the wiring pattern 271 of the constant current circuit unit 241 by soldering or the like, and makes the transistor element 245 and the wiring pattern 271 conductive.

By attaching the transistor element 245 to such an adapter 261, the transistor element 245 can be removed from the constant current circuit more smoothly.
Note that the transistor element 245 may be attached to the adapter 261 using a conductive paste (eg, silver paste) with low adhesive strength. Alternatively, the transistor element 245 can be attached to the constant current circuit portion 241 by using a conductive paste with low adhesive strength.

The engagement portion 344 is formed with an insertion recess 345 into which the engagement plate portion 335 is inserted. Further, a coupling hole 347 through which a coupling tool is passed is formed in the engagement portion 344 at a position corresponding to the coupling hole 337 of the engagement plate portion 335. A coupling pin 351 as a coupling tool is inserted into the coupling holes 337 and 347, and the case main body 321 and the cover member 325 are coupled.

The cover member 325 is made of a translucent material such as a translucent resin or glass, and transmits the output light of the LED module 11 to the front side. Further, the outer surface of the cover member 325 is subjected to a satin finish treatment.
(LED module, lighting circuit, wiring)
The LED module 11 is the same as that of the first embodiment.

The lighting circuit 313 has an AC / DC conversion function and a voltage adjustment function.
The lighting circuit 313 is connected to the base 316 by a lead wire 361 serving as a wiring member and receives supply of AC power. The lighting circuit 313 is connected to two lead wires 363a and 363b that supply output DC power. The lead wire 363 a passes through the hole of the support plate 323 and is connected to the LED module 11. On the other hand, the lead wire 363b is connected to the LED module 11 via the power supply path cutting mechanism 317 and the lead wire 363c.

With the above configuration, the lighting device 301 is turned on when power is supplied to the base 316.
(Power supply line cutting mechanism)
The power feeding path cutting mechanism 317 includes a cutting target part 371 that is a part to be cut in the power feeding path, and a string member 373 that connects the coupling pin 351 and the cutting target part 371.
(About the cutting target part)
The cutting target part 371 includes first and second conductive terminals 381a and 381b. The first conductive terminal 381 a extends in a direction orthogonal to the support plate 323 and is provided through the support plate 323. Then, on the back side of the support plate 323, the lead wire 363b is connected. Further, in the first conductive terminal 381a, the connection portion 383 protruding to the front side of the support plate 323 is electrically connected to the second conductive terminal 381b by contact. The connecting portion 383 is coupled to the string member 373 at the tip portion. In the vicinity of the support plate 323 of the connecting portion 383, a weak portion is formed by a notch 385 to facilitate cutting. Of the first conductive terminal 381a, the portion other than the connection portion 383 constitutes the “terminal portion”.

The second conductive terminal 381b is brought into surface contact with the connection portion 383 of the first conductive terminal 381a and is electrically connected to the first conductive terminal 381a. The second conductive terminal 381b is connected to the lead wire 363c. The second conductive terminal 381b constitutes the “terminal portion”.
Note that the first and second conductive terminals 381a, 38b and the support plate 323 are electrically insulated.

(About connecting pins)
19A and 19B are a sectional view and a front view of the coupling pin 351. FIG.
The coupling pin 351 has a base 401 made of a metal material on the base side and a locking portion 403 made of a resin material on the tip side. The base portion 401 has a cylindrical shape, and includes a cylindrical portion 405 and a head portion 407 whose outer diameter is increased. A surface 409 of the head portion 407 on the cylindrical portion 405 side is inclined such that the outer peripheral side approaches the end portion. The coupling pin 351 couples the case main body 321 and the cover member 325 by preventing the engaging portion 344 and the engaging plate portion 335 from shifting in the shearing direction by the base 401.

The locking portion 403 includes a central disc portion 411, a cylindrical projecting portion 413 projecting from the disc portion 411 toward the base 401 side, and a claw portion projecting from the disc portion 411 toward the front end side. 415. In addition, a groove 417 is formed on the outer periphery of the base end portion (near the disc portion 411) of the projecting portion 413, and the strength between the projecting portion 413 and the disc portion 411 is weakened and is easily broken. ing.
The locking portion 403 is formed with a through hole 421 that penetrates the disc portion 411 and the protruding portion 413 in the axial direction.

The protruding portion 413 is inserted into the through hole 423 of the base portion 401 and joined to the base portion 401 by adhesion or the like. And the through hole 421 of the latching | locking part 403 and the through hole 423 of the base 401 are connected. Note that the projecting portion 413 and the base portion 401 can be joined by screwing.
The locking portion 403 is engaged with the inner peripheral wall surface 424 of the opening end portion 343 by the claw portion 415 and locked so that the coupling pin 351 does not come out of the coupling holes 337 and 347.

In one of the two coupling pins 351a and 351b shown in FIG. 17, a string member 373 is inserted into the through holes 421 and 423. Further, the end of the string member 373 is fixed by a plug 425 sealed in the through hole 423 of the base 401. The string member 373 may be fixed to the base 401 by other methods such as adhesion.
The structure of the two coupling pins 351a and 351b is the same, and whether or not they are connected to the string member 373 is different. The coupling pin 351a coupled to the string member 373 is a “specific coupling tool”, and the coupling pin 351b not coupled to the string member 373 is a “general coupling tool”.

<Operation>
(About unbinding)
The operation | movement at the time of the disassembly of the illuminating device 1 in this embodiment is demonstrated.
When the lighting device 301 is disassembled, the connecting pin 351 is pulled out by a driver, pliers, or the like (release operation). At that time, the coupling pin 351 is configured such that the locking portion 403 is broken and only the base portion 401 is detached. That is, since the locking portion 403 is relatively easily broken at the portion made weak by the groove 417, only the base portion 401 (to be exact, the protruding portion 413 is also incidentally removed) is released. Then, the locking portion 403 remains in the coupling hole 347. When a driver is used for releasing the coupling, the coupling pin 351 can be easily pulled out by inserting the tip of the driver into a gap formed by the inclined surface 409 of the head 407 of the coupling pin 351. it can.

When the base 401 is pulled out from the coupling holes 337 and 347, the coupling between the case main body 321 and the cover member 325 is released. In this embodiment, since the two coupling pins 351a and 351b are attached, it is necessary to remove both base portions 401.
Here, a case where the coupling pin 351a is pulled out will be described.
One end of the string member 373 is joined to the base 401a of the coupling pin 351a. Therefore, the string member 373 is pulled when the base 401a is pulled out. The other end of the string member 373 is joined to the connection portion 383 of the first conductive terminal 381a. As a result, the connecting portion 383 is disconnected from the first conductive terminal 381a by the string member 373. As described above, the notch 385 is formed in the first conductive terminal 381a, and the connection portion 383 and the second conductive terminal 381b are merely brought into contact with each other, so that the connection portion 383 can be separated relatively easily. be able to.

That is, the power supply path is cut in conjunction with the release operation of the connection by the connection pin 351a, and the LED module 11 does not light up. Further, even if the base portion 401a of the coupling pin 351a is reinserted into the coupling holes 337 and 347, conduction is not restored.
Further, even if the cutting target portion 371 is repaired, some means for maintaining the state in which the base portion 401 is inserted into the connecting holes 337 and 347 is required because the connecting pin 351a is broken.

(About assembly)
A procedure for joining the case main body 321 and the cover member 325 will be described.
The engagement plate portion 335 of the case main body 321 is inserted into the insertion recess 345 of the cover member 325. Then, the end of the string member 373 is pulled out from the coupling holes 337 and 347 into which the coupling pin 351a is inserted. In that case, an appropriate instrument such as one in which the tip of a wire is bent in a U shape can be used. Further, before the engagement plate portion 335 is inserted into the insertion recess 345, the string member 373 may be temporarily fixed to the inner wall of the coupling hole 347 (the inner peripheral side from the engagement plate portion 335) with an adhesive tape or the like. .

  The drawn string member 373 is inserted into the through holes 421 and 423 from the distal end side of the coupling pin 351a and pulled out from the proximal end side. The coupling pin 351a is inserted into the coupling holes 337 and 347 so that the string member 373 is not sandwiched between the coupling pin 351a and the inner walls of the coupling holes 337 and 347, and the claw portion 415 is attached to the inner peripheral wall surface 424. Engage. The string member 373 is pulled out until there is no looseness, the stopper 425 is sealed in the through hole 423 from the base end side of the coupling pin 351a to fix the string member 373, and then the excess string member 373 is cut off. The string member 373 may be fixed to the inner peripheral surface of the through hole 423 by adhesion.

Thus, the lighting device 301 can be easily assembled.
By passing the string member 373 through the through holes 421 and 423 of the coupling pin 351, relative movement between the coupling pin 351 and the string member 373 is allowed at the time of coupling, and the coupling pin 351 and the string member 373 are engaged at the time of releasing the coupling. It can be combined. That is, the through holes 421 and 423 function as a passage for passing the string member 373.

<Operational effects and others>
The lighting device 301 facilitates disassembly at the time of recycling, cuts the power supply path at the time of disassembly, breaks the connecting pin 351a, makes it difficult to reassemble and use, and suppresses unnecessary disassembly. Can do.
In the present embodiment, the “operation part” is configured by the stopper 425 and the end of the string member 373 fixed to the base 401 by the stopper 425. The string member 373 constitutes the “connecting portion”.

The support plate 507 corresponds to the support plate 23 (or 323). Further, a plate-like member is interposed between the LED module 11 and the support plate 507, which will be described later.

The holding member 503 includes a flat plate portion 511 fixed by the screw member 505 and an “inverted L-shaped portion 513” standing on the end of the flat plate portion 511. The inverted L-shaped portion 513 fixes the LED module 11 by contacting the side surface and the upper surface (the main surface on which the LED element 55 is provided) of the substrate 51.
Each of the pressing members 503b to 503d and the two screw members 505 constitute a “general coupler”. In addition, the “specific coupler” is configured by the pressing member 503a and the screw member 505a.

(Power supply line cutting mechanism)
The power supply path cutting mechanism 501 includes an interposed plate 521 interposed between the LED module 11 and the support plate 507 and two elastic force accumulation units 523 embedded in the support plate 507.
(Intermediate plate)
The intervening plate 521 includes a rotating plate 531, a fixed plate 533, and a hinge 535 that couples them in a rotatable manner.

  The rotation plate 531 is formed with a through hole 541 through which the screw member 505a is passed. The rotating plate 531 is coupled to the support plate 507 together with the pressing member 503a by the screw member 505a passing through the through hole 541. That is, the rotating plate 531 is coupled to the support plate 507 by the specific coupling tool together with the LED module 11. In addition, a concave contact portion 543 that contacts the two elastic force accumulation portions 523 is formed on the surface of the rotating plate 531 on the support plate 507 side.

  The fixing plate 533 is formed with six through holes 551 through which the six screw members 505b to 505d pass. The fixing plate 533 is coupled to the support plate 507 together with the pressing members 503b to d by screw members 505b to 505d passing through the through holes 551. In the present embodiment, the fixing plate 533 is fixed to the support plate 507 together with the LED module 11 by a general coupler, and the number of couplers can be reduced. However, the fixing plate 533 may be fixed to the support plate 507 separately from the LED module 11.

A hinge 535 serving as a connecting member is located on the LED module 11 side of the rotating plate 531 and the fixed plate 533, and is connected so as to be rotatable around a rotation axis along the boundary line thereof.
The rotating plate 531 constitutes the “first plate member”, and the fixed plate 353 constitutes the “second plate member”.

(Elastic force accumulation part)
The elastic force accumulation unit 523 includes a cylindrical cylinder 561 whose one end is closed, a piston member 563 accommodated in the cylinder 561, and a spring member 565 that generates an elastic force in a direction in which the piston member 563 is pushed out. ing.
The cylinder 561 is inserted into a through hole 567 formed in the support plate 507, and is provided in a state in which movement to the opposite side to the rotation plate 531 is disabled. The piston member 563 has a cylindrical shape in which the rotating plate 531 side is closed, and the inside is hollow. Further, the portion that contacts the rotating plate 531 is convex.

  A spring member 565 is accommodated in the piston member 563. The spring member 565 is a compression coil spring, and is compressed and deformed by the piston member 563 in a state where the rotating plate 531 is coupled, and a restoring force due to an elastic force is accumulated. By this restoring force, the piston member 563 is moved to the rotating plate 531 side, and the interposed plate 521 is urged in a direction to be bent to the LED module 11 side.

(Coating member)
FIG. 22 shows the covering member 571.
The covering member 571 is provided so as to cover each pressing member 503, the screw members 505b to 505d, and the hinge 535. The covering member 571 is open at the center, and the screw member 505a and the LED module 11 are exposed. When the LED module 11 is removed by the covering member 571, the screw member 505a is first released from the coupling operation.

The covering member 571 includes an engaging portion 573 that engages with the pressing member 503d and a coupled portion 575 that is coupled by the screw member 505a. The coupled portion 575 is formed with a through hole through which the screw member 505a is passed. The covering member 571 is attached on the interposed plate 521 at the engaging portion 573 and the coupled portion 575.
(LED module)
The LED module 11 is the same as that of the first embodiment, and two notches 581 are formed. 20 to 22 show a notch 581 on the side portion of the substrate 51 (the portion adjacent to the hinge 535), but as shown in FIG. 23, the back surface of the substrate 51 (the support plate 507 side). The V-cut 583 (V-shaped cut) is also formed on the straight line connecting the two notches 581. When the LED module 11 is fixed on the interposed plate 521, the notch 581 and the V-cut 583 are positioned on the boundary line between the rotating plate 531 and the fixed plate 533.

The portions where the notches 581 and the like are formed are fragile, and the substrate 51 is easily broken. That is, the substrate 51 is easily broken.
In the LED module 11, the portion located on the rotating plate 531 constitutes the “first portion”, and the portion located on the fixed plate 533 constitutes the “second portion”. Further, a notch 581 or the like is formed at the boundary between the first portion and the second portion.

The substrate 51 of the LED module 11 is such that an insulating layer (for example, resin) is laminated on a metal layer (such as aluminum) as described above, but is not limited thereto. The substrate 51 can be, for example, a ceramic substrate made of alumina or aluminum nitride, or a glass epoxy substrate.
<Operation>
(About unbinding)
The operation | movement at the time of removal of the LED module 11 of the illuminating device in this embodiment is demonstrated. FIGS. 23A and 23B show the state before and after the operation by omitting the illustration of the holding members 503b and c and the screw members 505b and c.

  When the LED module 11 is removed, the screw member 505a is rotated in the coupling release direction by a driver or the like (coupling release operation). By this coupling release operation, the screw member 505a is moved in a direction (separation direction) away from the support plate 507. The rotating plate 531 is rotated by the piston member 563 with the movement of the screw member 505a. At this time, the rotating plate 531 rotates around the connecting shaft of the hinge 535 so as to rise from the end opposite to the hinge 535. As a result, the substrate 51 of the LED module 11 installed on the rotating plate 531 is deformed so as to be bent.

Further, when the screw member 505a is rotated in the coupling release direction and moved in the disengagement direction, the broken surface of the substrate 51 of the LED module 11 is widened and cracked starting from the notch 581 and the like. As a result, the wiring pattern on the substrate 51 is cut and the LED module 11 cannot be turned on.
As described above, the rotating plate 531 urged by the elastic force accumulating portion 523 is mechanically linked by coming into contact with the screw member 505a, and the power supply path cutting mechanism 501 is separated from the screw member 505a. The wiring pattern serving as a power feeding path is cut in conjunction with the movement (releasing operation) to the position of the rotary plate 531. Note that the through hole 541 of the rotating plate 531, the through hole 585 of the pressing member 503a, and the covering member 571 The cross-sectional shape of the through hole of the coupled portion 575 (cross section parallel to the support plate 507) is a long hole that is elongated in the direction in which the rotating plate 531 and the fixed plate 533 are arranged. The elongated hole shape prevents the screw member 505a and the rotation plate 531 from interfering even when the rotation plate 531 is rotated.

(About installation)
A method for attaching the LED module 11 will be described. First, the pressing member 503a and the covering member 571 are placed on the interposed plate 521, and the screw member 505a is passed through the through hole 541 and the like of the rotating plate 531. These are moved closer to the support plate 507, and the contact portion 543 of the rotation plate 531 is brought into contact with the piston member 563. Then, the piston member 563 is pushed into the cylinder 561 by the rotating plate 531, and the spring member 565 is compressed. While maintaining this state by pressing the rotating plate 531 with a jig or a hand, the screw member 505a is rotated in the coupling direction to perform temporary fixing.

  Further, the LED module 11 is placed on the interposed plate 521, and the pressing members 503b to 503d are temporarily fixed by the screw members 505b to 505d in an arbitrary order. Note that the covering member 571 can be elastically deformed relatively easily, and when the screw members 505b to 505d are temporarily fixed, the portion on the pressing member 503d side of the covering member 571 is set upward (the support plate 507). (In a direction away from the head), the work can be performed.

  After the temporary fixing operation, the positional relationship between the LED module 11 and each pressing member 503 is adjusted, and each screw member 505 is tightened with a predetermined torque. The screw member 505a is preferably tightened last, and before that, the engaging portion 573 of the covering member 571 is engaged with the pressing member 503d. Then, after adjusting the positions of the pressing member 503a and the covering member 571, the screw member 505a is tightened.

Thus, the mounting of the LED module 11 is completed. In addition, the operation | work which connects a lead wire to the connection terminal 58 can be performed after attachment of the LED module 11, for example.
<Effect>
The lighting device of this embodiment can easily remove the LED module 11 during recycling. When the LED module 11 is unnecessarily removed, the power supply path cutting mechanism 501 breaks the substrate 51 of the LED module 11 and disconnects the power supply path, thereby making the LED module 11 unusable. Thereby, it can suppress that the LED module 11 is removed unnecessarily. Further, by breaking the substrate 51, it is possible to prevent diversion of the LED module 11 whose lifetime has been shortened.

<Modifications>
The elastic force accumulating portion 523 can use a spring member other than the compression coil spring, such as a leaf spring. Moreover, the elastic force storage part 523 provided in the power supply path cutting mechanism 501 can be made one.
The number, depth, and the like of the notches 581 and V cuts 583 formed in the LED module 11 can be changed according to the strength of the substrate 51, the magnitude of the elastic force of the spring member 565, and the like. Further, the substrate 51 can be provided with a through hole to reduce the strength of the substrate 51.
