Each of the embodiments described below shows a preferred specific example of the present invention. The numerical values, shapes, materials, constituent elements, arrangement positions and connecting forms of the constituent elements, steps, order of steps, and the like shown in the following embodiments are merely examples, and are not intended to limit the present invention. In addition, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims indicating the highest concept of the present invention are described as optional constituent elements that constitute a more preferable embodiment. In the drawings, elements that represent substantially the same configuration, operation, and effect are denoted by the same reference numerals. Each figure is a schematic diagram and is not necessarily illustrated exactly.

  First, the whole structure of the light bulb shaped lamp 1 according to the embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a side view of a light bulb shaped lamp 1 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the light bulb shaped lamp 1 according to the embodiment of the present invention. FIG. 3 is a cross-sectional view of the light bulb shaped lamp 1 according to the embodiment of the present invention.

  The light bulb shaped lamp 1 is a light bulb shaped LED lamp that is a substitute for a light bulb shaped fluorescent light or an incandescent light bulb. The light bulb shaped lamp 1 includes a translucent globe 10, an LED module 2 as a light source, a support column 40, a support plate 50, a resin case 60, a lead wire 70, a lighting circuit 80, and power from outside the lamp. And a base 90 for receiving.

  In the light bulb shaped lamp 1, an envelope is configured by the globe 10, the resin case 60 (first case portion 61), and the base 90. Here, in the following description, the Z-axis plus direction shown in these drawings is described as the upper side, and the Z-axis minus direction is set as the lower side. That is, the globe 10 is disposed above the base 90. The definition of the above direction is independent of the direction when the light bulb shaped lamp 1 is attached to the lighting fixture, and when the light bulb shaped lamp 1 is attached to the lighting fixture, any direction is upward or downward. It doesn't matter.

[Glove]
The globe 10 houses the LED module 2. The globe 10 is a light-transmitting globe that is made of a material that is transparent to the light from the LED module 2 and transmits the light from the LED module 2 to the outside of the lamp. Such a globe 10 can be a glass bulb (clear bulb) made of silica glass that is transparent to visible light. In this case, the LED module 2 housed in the globe 10 can be viewed from the outside of the globe 10.

  The shape of the globe 10 is such that one end is closed in a spherical shape and the other end has an opening 11. Specifically, the shape of the globe 10 is such that a part of the hollow sphere narrows while extending in the direction away from the center of the sphere (Z-axis minus direction), and the position away from the center of the sphere. An opening 11 is formed in the opening. As the globe 10 having such a shape, a glass bulb having the same shape as a general incandescent bulb can be used. For example, a glass bulb such as an A shape, a G shape, or an E shape can be used as the globe 10.

  The globe 10 is not necessarily transparent to visible light, and the globe 10 may have a light diffusion function. For example, a milky white light diffusing film may be formed by applying a resin containing a light diffusing material such as silica or calcium carbonate, a white pigment, or the like to the entire inner surface or outer surface of the globe 10. Moreover, the globe 10 does not need to be made of silica glass. For example, a globe 10 made of a resin material such as acrylic may be used.

[LED module]
The LED module 2 is a light emitting module that has an LED (LED chip) and emits light when electric power is supplied to the LED through a lead wire 70. The LED module 2 is held in a hollow state in the globe 10 by the support column 40.

  The LED module 2 is preferably arranged at a spherical center position formed by the globe 10 (for example, inside the large diameter portion where the inner diameter of the globe 10 is large). Thus, by arranging the LED module 2 at the center position of the globe 10, the light distribution characteristic of the light bulb shaped lamp 1 becomes a light distribution characteristic approximate to that of a general incandescent light bulb using a conventional filament coil.

  The detailed configuration of the LED module 2 will be described later.

[Base]
The base 90 is a power receiving unit that receives power for causing the LEDs of the LED module 2 to emit light from the outside of the light bulb shaped lamp 1. The base 90 receives AC power through two contact points, and the power received by the base 90 is input to the power input unit of the lighting circuit 80 via a lead wire. The base 90 is attached to a socket of a lighting fixture (lighting device), and turns on the light bulb shaped lamp 1 (LED module 2) by receiving power from the socket.

  For example, the base 90 is E-shaped, and a screwing portion for screwing into the socket of the lighting device is formed on the outer peripheral surface thereof, and a screwing portion for screwing the resin case 60 on the inner peripheral surface thereof. Is formed. The base 90 has a bottomed cylindrical shape made of metal. As the base 90, an E26 type or E17 type base can be used in addition to a screw-type Edison type (E type) base.

[Support]
The support column 40 is a stem provided so as to extend upward (inward of the globe 10) from the vicinity of the opening 11 of the globe 10, and functions as a holding member that holds the LED module 2 in the globe 10. One end of the column 40 is connected to the LED module 2, and the other end is connected to the support plate 50. That is, the upper surface of the support column 40 is in contact with the lower surface of the LED module 2, and the support column 40 and the LED module 2 are bonded to each other by a resin adhesive such as a silicone resin.

  The support column 40 also functions as a heat radiating member for radiating heat generated in the LED module 2 to the base 90 side. Accordingly, the heat radiation efficiency of the support column 40 can be increased by forming the support column 40 from a metal material having a high thermal conductivity, for example, aluminum having a thermal conductivity of 237 [W / m · K]. As a result, it is possible to suppress a decrease in light emission efficiency and lifetime of the LED due to temperature rise. In addition, the support | pillar 40 can also be comprised with resin etc.

[Support plate]
The support plate 50 is a member that supports the support column 40 and is fixed to the resin case 60. The support plate 50 is connected to the opening end of the opening 11 of the globe 10 and is configured to close the opening 11 of the globe 10. Specifically, the support plate 50 is formed of a disk-shaped member having a step portion on the periphery, and the opening end of the opening portion 11 of the globe 10 is in contact with the step portion. And in this level | step-difference part, the support plate 50, the resin case 60, and the opening end of the opening part 11 of the globe 10 are adhere | attached with the adhesive agent.

  Similarly to the support column 40, the support plate 50 is made of a metal material having a high thermal conductivity such as aluminum, so that the heat radiation efficiency of the LED module 2 that conducts the support column 40 by the support plate 50 is increased. As a result, it is possible to further suppress the decrease in light emission efficiency and lifetime of the LED due to temperature rise.

[Resin case]
The resin case 60 is an insulating case (circuit holder) that insulates the support column 40 and the base 90 and houses the lighting circuit 80. The resin case 60 has a large-diameter cylindrical first case portion 61 and a small-diameter cylindrical second case. The case part 62 is comprised. The resin case 60 can be molded by, for example, polybutylene terephthalate (PBT).

  Since the outer surface of the first case portion 61 is exposed to the outside air, the heat conducted to the resin case 60 is mainly radiated from the first case portion 61. The second case portion 62 is configured such that the outer peripheral surface is in contact with the inner peripheral surface of the base 90, and a screwing portion for screwing with the base 90 is formed on the outer peripheral surface of the second case portion 62. ing.

[Lead]
The two lead wires 70 are wire-like metal wires such as copper wires for supplying power for lighting the LED module 2 from the lighting circuit 80 to the LED module 2. Each lead wire 70 is arranged in the globe 10, one end is electrically connected to the external terminal of the LED module 2, and the other end is electrically connected to the power output unit of the lighting circuit 80, in other words, the base 90. Yes. That is, the two lead wires 70 are a pair of lead wires for electrically connecting the first light emitting module 20 and the second light emitting module 30 to be described later and the lighting circuit 80. The lead wire 70 also functions as a support part that supports the LED module 2 by being partly connected to an external terminal of the LED module 2.

  The two lead wires 70 are, for example, vinyl wires composed of a metal core wire and an insulating resin that covers the core wire, and the LED module 2 is not covered with the insulating resin and the surface thereof is exposed. It is electrically connected via a core wire.

  The details of the connection relationship between the lead wire 70 and the LED module 2 will be described later.

[Lighting circuit]
The lighting circuit 80 is a circuit unit for lighting the LEDs of the LED module 2, and includes a plurality of circuit elements and a circuit board on which each circuit element is mounted. The lighting circuit 80 converts AC power supplied from the base 90 into DC power, and supplies the converted DC power to the LEDs of the LED module 2 via the two lead wires 70. That is, the lighting circuit 80 is a drive circuit for supplying power to the first light emitting element 22 and the second light emitting element 32 described later.

  The light bulb shaped lamp 1 does not necessarily need to include the lighting circuit 80. For example, when direct-current power is directly supplied to the light bulb shaped lamp 1 from a lighting fixture or a battery, the light bulb shaped lamp 1 may not include the lighting circuit 80. The lighting circuit 80 is not limited to a smoothing circuit, and can be configured by appropriately selecting and combining a dimming circuit and a booster circuit.

  As such phosphor particles, when the first light emitting element 22 is a blue LED that emits blue light, in order to emit white light from the first sealing member 23, fluorescence that converts the wavelength of the blue light into yellow light. Body particles are used. For example, YAG (yttrium / aluminum / garnet) -based yellow phosphor particles can be used as the phosphor particles. As a result, part of the blue light emitted from the first light emitting element 22 is converted into yellow light by the yellow phosphor particles contained in the first sealing member 23. Then, the blue light that is not absorbed by the yellow phosphor particles (not wavelength-converted) and the yellow light that is wavelength-converted by the yellow phosphor particles are diffused and mixed in the first sealing member 23. As a result, the first sealing member 23 emits white light. In addition to the yellow phosphor particles, green phosphor particles, red phosphor particles, or the like may be used as the phosphor particles. When the first light emitting element 22 is the first light emitting element 22 that emits ultraviolet rays, wavelength conversion is performed. As the phosphor particles that are the materials, those obtained by combining phosphor particles that emit light in three primary colors (red, green, and blue) are used.

  On the other hand, as the resin material containing the phosphor particles, a transparent resin material such as a silicone resin, an organic material such as a fluorine-based resin, an inorganic material such as low-melting glass and sol-gel glass, and the like can be used.

[Insert member]
Next, the insertion member 39 will be described in detail with reference to FIG. FIG. 7 is a perspective view showing an appearance of the insertion member 39 according to the embodiment of the present invention.

  As shown in FIGS. 5 and 7, the insertion member 39 is a conductive member inserted into the first through hole 21a and the second through hole 31a. The insertion member 39 has an upper portion electrically connected to the first terminal 28 and a lower portion electrically connected to the second terminal 38, thereby electrically connecting the first terminal 28 and the second terminal 38. Connecting. The insertion member 39 forms an insertion path for inserting the lead wire 70 into the first through hole 21a and the second through hole 31a. The material of the insertion member 39 may be any material as long as it has conductivity. For example, copper (Cu), tin (Sn), nickel (Ni), platinum (Pt), cobalt, which are easy to solder. (Co), iron (Fe), and alloys thereof, and those plated with them are used. Here, the insertion member 39 includes a cylindrical main body 39a and a protruding portion 39b protruding outward. That is, the insertion member 39 is a hollow pin in which a through hole 39c penetrating in the vertical direction is formed. The lead wire 70 is inserted into the first through hole 21a and the second through hole 31a by being inserted into the insertion member 39 using the through hole 39c as an insertion path.

  The main body 39a is a cylindrical portion extending in the vertical direction and inserted into the first through hole 21a and the second through hole 31a. Although the length of the main body 39a in the vertical direction is not limited, it is preferable that the upper portion of the main body 39a protrudes from the upper surface of the first base 21. The main body 39a has a shape corresponding to the first through hole 21a and the second through hole 31a.

  That is, since the first through hole 21a and the second through hole 31a are through holes having a circular cross section, the main body portion 39a has a cross section in the horizontal plane (XY plane) of the first through hole 21a and the second through hole 31a. And has a circular outer shape of approximately the same size. Thereby, the insertion member 39 restrict | limits the position of the 2nd through-hole 31a with respect to the 1st through-hole 21a by being inserted in the 1st through-hole 21a and the 2nd through-hole 31a. The first through-hole 21a and the second through-hole 31a are square-shaped through-holes, and the main body 39a has a cross section in the XY plane that is substantially the same as the cross-section of the first through-hole 21a and the second through-hole 31a. You may decide to have a square-shaped outer shape.

  The protruding portion 39b is a disk-shaped portion that is provided below the insertion member 39 and protrudes outward from the periphery of the main body portion 39a, and is electrically connected to the second terminal 38. In addition, the protrusion part 39b and the 2nd terminal 38 do not need to contact, and the protrusion part 39b and the 2nd terminal 38 should just be electrically connected via the 2nd electroconductive member 37.

  In the LED module 2 of FIG. 4, the current supplied to one of the positive lead wires 70 includes the first conductive member 27, the first terminal 28, the first metal wiring 26, the first light emitting element 22, and the first light emitting element 22. It passes through one metal wiring 24 and is output from the other negative lead wire 70. Similarly, the current supplied to one plus-side lead wire 70 is the first conductive member 27, the insertion member 39, the second conductive member 37, the second terminal 38, the second metal wiring 36, the second light emission. The light passes through the element 32 and the second metal wiring 34 and is output from the other lead wire 70 on the negative side.

  As described above, according to the light bulb shaped lamp 1 according to the embodiment of the present invention, the conductive insertion member 39 is provided. Here, the insertion member 39 is inserted into the first through hole 21 a of the first light emitting module 20 and the second through hole 31 a of the second light emitting module 30. As described above, the insertion member 39 is inserted into the first through hole 21a and the second through hole 31a, so that the insertion member 39 positions the first through hole 21a and the second through hole 31a. It is possible to prevent the displacement between the through hole 21a and the second through hole 31a.

  The insertion member 39 forms an insertion path for inserting the lead wire 70 into the first through hole 21a and the second through hole 31a. In this way, the insertion member 39 prevents the first through hole 21a and the second through hole 31a from being blocked by the adhesive member, and forms an insertion path for the lead wire 70, whereby the lead wire 70 passes through the first through hole. The holes 21a and the second through holes 31a can be inserted and connected.

  In addition, the insertion member 39 is electrically connected to the first terminal 28 of the first light emitting module 20 at the upper part and electrically connected to the second terminal 38 of the second light emitting module 30 at the lower part. The terminal 28 and the second terminal 38 are electrically connected. Thus, the insertion member 39 needs to electrically connect the lead wire 70 to both the first terminal 28 and the second terminal 38 by electrically connecting the first terminal 28 and the second terminal 38. The lead wire 70 may be electrically connected to the first terminal 28 or the second terminal 38.

  The insertion member 39 of the light bulb shaped lamp 1 has an outer shape corresponding to the first through hole 21a and the second through hole 31a, and is inserted into the first through hole 21a and the second through hole 31a. Thus, the position of the second through hole 31a with respect to the first through hole 21a is regulated. As a result, the insertion member 39 can more accurately position the first through hole 21a and the second through hole 31a, and the displacement between the first through hole 21a and the second through hole 31a is further increased. Can be prevented. For this reason, positioning with the 1st base 21 and the 2nd base 31 can be performed correctly.

  Moreover, the insertion member 39 of the light bulb shaped lamp 1 is a hollow pin in which a through hole 39c is formed, and the lead wire 70 is inserted into the insertion member 39 using the through hole 39c as an insertion path. 21a and the second through hole 31a. Thereby, the insertion member 39 can more reliably prevent the first through hole 21a and the second through hole 31a from being blocked by the adhesive member, and the lead wire 70 can be turned into the first through hole 21a and the second through hole 31a. Easy to insert and connect.

  Further, the insertion member 39 of the light bulb shaped lamp 1 has a protruding portion 39 b, and the protruding portion 39 b is electrically connected to the second terminal 38. Thereby, by electrically connecting the protrusion 39b of the insertion member 39 and the second terminal 38, the insertion member 39 and the second terminal 38 can be easily electrically connected.

  The light bulb shaped lamp 1 includes a first conductive member 27 that covers the upper portion of the lead wire 70, the upper portion of the insertion member 39, and the first terminal 28, and includes an upper portion of the lead wire 70 and an upper portion of the insertion member 39. The first terminal 28 is electrically connected through the first conductive member 27. That is, after inserting the lead wire 70 into the insertion member 39, the first conductive member 27 covers the upper portion of the lead wire 70, the upper portion of the insertion member 39, and the first terminal 28. The insertion member 39 and the first terminal 28 can be electrically connected.

  As described above, in the light bulb shaped lamp 1 having a configuration in which two light emitting modules are bonded together, productivity when the lead wire 70 is connected to the two light emitting modules can be improved.

  Next, a method for manufacturing the light bulb shaped lamp 1 will be described.

  FIG.8 and FIG.9 is a flowchart which shows the manufacturing method of the lightbulb-shaped lamp 1 which concerns on embodiment of this invention. Specifically, FIG. 8 is a flowchart showing a method for connecting the LED module 2 and the lead wire 70. FIG. 9 is a flowchart showing in detail a second connection step for electrically connecting the first terminal 28 and the upper portion of the insertion member 39.

  Moreover, FIG. 10 is a figure for demonstrating the manufacturing process of the lightbulb-shaped lamp 1 which concerns on embodiment of this invention.

  As shown in FIG. 8, first, as a first insertion step, an insertion path for inserting the lead wire 70 into the second through hole 31a is formed by inserting the insertion member 39 into the second through hole 31a ( S102). Specifically, as shown in FIG. 10A, an insertion member 39 is disposed below the second base 31, and as shown in FIG. 10B, the insertion member is inserted into the second through hole 31a. 39 is inserted.

  Then, returning to FIG. 8, as the first connection step, the second terminal 38 and the lower portion of the insertion member 39 are electrically connected (S104). Specifically, as shown in FIG. 10C, the protrusion is formed by soldering with the second conductive member 37 so as to cover the tip of the protrusion 39b of the insertion member 39 and the second terminal 38. The part 39b and the second terminal 38 are electrically connected.

  Then, returning to FIG. 8, as a second insertion step, an insertion path for inserting the lead wire 70 into the first through hole 21a is formed by inserting the insertion member 39 into the first through hole 21a (S106). . Specifically, as shown in FIG. 10 (d), the first base 21 is disposed above the second base 31, and the insertion member 39 is inserted into the first through hole 21a.

  Then, returning to FIG. 8, as the second connection step, the first terminal 28 and the second terminal 38 are electrically connected by electrically connecting the first terminal 28 and the upper portion of the insertion member 39 ( S108). Below, this 2nd connection process is demonstrated in detail using FIG.

  First, as shown in FIG. 9, the lead wire 70 is inserted into the first through hole 21a and the second through hole 31a (S202). Specifically, as shown in FIG. 10E, the lead wire 70 is inserted into the through hole 39 c of the insertion member 39.

  Returning to FIG. 9, the upper portion of the lead wire 70, the upper portion of the insertion member 39, and the first terminal 28 are electrically connected (S204). Specifically, as shown in FIG. 10F, by soldering with the first conductive member 27 so as to cover the upper portion of the lead wire 70, the upper portion of the insertion member 39, and the first terminal 28, The lead wire 70, the insertion member 39, and the first terminal 28 are electrically connected.

  As described above, according to the method for manufacturing the light bulb shaped lamp 1 according to the embodiment of the present invention, the lead wire 70 is inserted into the second through hole 31a of the second light emitting module 30 by inserting the insertion member 39. A first insertion step of forming an insertion path for insertion into the two through holes 31a is included. Thereby, the insertion member 39 can prevent the second through hole 31a from being blocked by the adhesive member.

  Further, the method for manufacturing the light bulb shaped lamp 1 includes a first connection step of electrically connecting the second terminal 38 and the lower part of the insertion member 39. That is, the second terminal 38 and the insertion member 39 are soldered before the first light emitting module 20 and the second light emitting module 30 are bonded together. Thereby, the process of soldering the second terminal 38 and the insertion member 39 after bonding the first light emitting module 20 and the second light emitting module 30 can be eliminated.

  Moreover, in the manufacturing method of the light bulb shaped lamp 1, the insertion path for inserting the lead wire 70 into the first through hole 21a is formed by inserting the insertion member 39 into the first through hole 21a of the first light emitting module 20. A second insertion step. Thereby, the insertion member 39 can prevent the first through hole 21a from being blocked by the adhesive member. Further, the insertion member 39 is inserted into the first through hole 21a and the second through hole 31a, so that the insertion member 39 positions the first through hole 21a and the second through hole 31a, and the first through hole It is possible to prevent the positional deviation between 21a and the second through hole 31a.

  Moreover, in the manufacturing method of the light bulb shaped lamp 1, the second connection for electrically connecting the first terminal 28 and the second terminal 38 by electrically connecting the first terminal 28 and the upper part of the insertion member 39. Process. Thus, the insertion member 39 needs to electrically connect the lead wire 70 to both the first terminal 28 and the second terminal 38 by electrically connecting the first terminal 28 and the second terminal 38. The lead wire 70 may be electrically connected to the first terminal 28 or the second terminal 38.

  Further, in the first connection step in the method for manufacturing the light bulb shaped lamp 1, the protrusion 39 b of the insertion member 39 and the second terminal 38 are electrically connected. Thereby, the insertion member 39 and the 2nd terminal 38 can be electrically connected easily.

  In the second connection step in the method of manufacturing the bulb-type lamp 1, the lead wire 70 is inserted into the first through hole 21a and the second through hole 31a, and the upper portion of the lead wire 70, the upper portion of the insertion member 39, and the first The terminal 28 is electrically connected. That is, after inserting the lead wire 70 into the insertion member 39, the first conductive member 27 covers the upper portion of the lead wire 70, the upper portion of the insertion member 39, and the first terminal 28. The insertion member 39 and the first terminal 28 can be electrically connected.

  As described above, in the method of manufacturing the light bulb shaped lamp 1 having a configuration in which two light emitting modules are bonded together, productivity when the lead wire 70 is connected to the two light emitting modules can be improved.

  Further, in the above configuration, since the area of the solder can be reduced particularly in the second base 31, the light reflectance at which the second base 31 reflects the light from the light emitting element is reduced by the solder portion. Therefore, the light extraction efficiency can be improved. That is, the substrate surface of the second base 31 is usually formed to have a high reflectance such as using a material having a light reflectance of 90% or more, but the surface of the solder has a low light reflectance. By reducing the area, it is possible to suppress the light reflectance of the second base 31 from being lowered.

  In the above configuration, since the area of the solder can be reduced in the second base 31, the contact area with the support column 40 can be increased, and the heat dissipation can be improved. That is, since it is necessary to set a predetermined distance sufficient to satisfy the dielectric strength between the solder portion of the second base 31 and the support column 40, the second base 31 and the support column can be reduced by reducing the solder portion. The contact area with 40 can be expanded.

  Moreover, in said structure, even when the 1st base 21 and the 2nd base 31 differ, the positioning at the time of bonding the 1st base 21 and the 2nd base 31 is attained. That is, when the first base 21 and the second base 31 have different shapes, positioning using the substrate shape cannot be performed, but positioning can be easily performed by using the insertion member 39. The effect by the said structure is large.

  Moreover, since the 1st base 21 and the 2nd base 31 are fixed to a horizontal direction with the insertion member 39, the deformation | transformation and curvature by the heat of the 1st base 21 and the 2nd base 31 are suppressed, and 1st The thermal contact between the base 21 and the second base 31 can be maintained. In other words, since the horizontal position restriction effect is obtained by the insertion member 39, an effect of preventing deformation or warping in a high temperature state can be expected. In particular, the first base 21 and the second base 31 are made of different materials or different. In the case of a thickness or the like, there is a concern about the occurrence of warpage or the like, so the effect is great.

Next, a modification of the light bulb shaped lamp according to the above embodiment will be described with reference to the drawings. The light bulb shaped lamp according to each modification described below and the light bulb shaped lamp 1 according to the above embodiment are different in the shape of the insertion member.

And are electrically connected. Further, the insertion member 339 and the first terminal 28 are covered with the first conductive member 27, whereby the insertion member 339 and the first terminal 28 are electrically connected.

In this case, the bulb-shaped lamp insertion member 539 according to Modification 5 includes an insulating member 539b disposed around the main body 539a.

  The insulating member 539b is a cylindrical member extending in the vertical direction, and is an insulating member arranged to cover the side surface of the main body 539a over the entire circumference. That is, the insulating member 539b is in contact with the first base 21 and the second base 31 (conduction) when the insertion member 539 is inserted into the first through hole 21a and the second through hole 31a. It arrange | positions so that it may not cover the main-body part 539a.

  In addition, since the first through hole 21a and the second through hole 31a are through holes having a circular cross section, the insulating member 539b has a cross section in the horizontal plane (XY plane) of the first through hole 21a and the second through hole 31a. And has a circular outer shape of approximately the same size. Thus, the insulating member 539b is also inserted into the first through hole 21a and the second through hole 31a, thereby playing a role of regulating the position of the second through hole 31a with respect to the first through hole 21a. The first through-hole 21a and the second through-hole 31a are square-shaped through-holes, and the insulating member 539b has substantially the same cross section in the XY plane as the first through-hole 21a and the second through-hole 31a. You may decide to have a square-shaped outer shape.

  Even with this configuration, the insertion member 539 can electrically connect the first terminal 28 and the second terminal 38 while ensuring insulation between the first base 21 and the second base 31. Even with the light bulb shaped lamp according to the fifth modification, the same effect as the light bulb shaped lamp 1 according to the above-described embodiment can be obtained.

A through hole 31b is formed.

  That is, a columnar protrusion 41a is formed at the center of the upper surface of the support column 41, and the first base 21 and the second base 31 are circular third through holes into which the protrusion 41a is inserted. 21b and a fourth through hole 31b are formed. The LED module 2 is positioned on the support column 41 by the projection 41a, the third through hole 21b, and the fourth through hole 31b.

  As described above, the first base 21 and the second base 31 may be formed with through holes not directly related to soldering other than the first through hole 21a and the second through hole 31a. The light bulb shaped lamp according to the sixth modification also has the same effect as that of the light bulb shaped lamp 1 according to the above embodiment even with this configuration.
