The first embodiment is a lighting device including a base in which a light emitting element is installed from the inside of a pedestal and the light emitting element and a power feeding unit are connected inside the base.

In the following figures, the same or corresponding parts are designated by the same reference numerals. In addition, halftone dots in each figure indicate electrical connection points. In this specification, the directions of up, down, right, and left are expressed with reference to the direction of the figure, but depending on the usage, the direction of up, down, right, and left can be selected arbitrarily, and vice versa or diagonally. Good.

As shown in the figure, a lighting device provided with this base may include a base 1 having a fixing function to an appliance and a power feeding function, and a light emitting element (hereinafter, also referred to as a "light emitting element" or a "light emitting element portion". ), A pedestal 3 of a light emitting element having a light emitting element installation part 31 and a base insertion part 32, and a drive board having a terminal part 4b connected to the inside of the shell of the base 1 of the base 1. 4. The LED drive circuit 4a provided on the substrate 4, the filler 5 filled inside the base 1, and the lid 6 for concealing the gap between the base 1 and the pedestal 3 of the light emitting element are provided. Will be done. If necessary, the cover 7 may be provided.

The pedestal 3 has an original shape in order to cope with the problem to be solved.
The light emitting element installation unit 31 is provided with a through hole for inserting the lead type LED 2 from below. Further, a constricted portion is provided inside the through hole, and the lead type LED 2 is positioned by contacting the collar 2b of the lead type LED 2.
The base insertion portion 32 is basically cylindrical so as to be in contact with the inside of the shell 1b of the base 1, but is provided with a notch 32b in order to provide a connection point with the drive board 4 inside the shell 1b. .. This notch is provided in the gap between the opening of the base 1 and the light emitting element installation portion 31 of the pedestal 3. For that reason, the light emitting element installation portion 31 may also be smaller than the opening of the base 1.

Since the terminals (4b, 4c, 4d) provided on the drive board 4 are formed in a normal manufacturing process for manufacturing the drive board 4, they can be manufactured at the same cost as a board without a terminal portion. .. A rod-shaped terminal 4b is provided on the lower portion of the drive board 4, and the tip of the terminal 4b is formed so that it can be directly soldered to the eyelet portion of the base 10. The terminal portion 4c is provided at a position in contact with the inside of the shell of the base 1 of the drive board 4.

The filler 5 has functions such as protection of electronic circuits, improvement of strength, and heat dissipation. Filling may be omitted if it is not necessary.

FIG. 11 is a perspective view when the lighting device according to the first embodiment of the present invention is provided with a cover.
FIG. 12 is a perspective view when a part of the pedestal of the lighting device according to the first embodiment of the present invention is used as a cover.

The cover 7 has a function of protecting the light emitting element 2 or making the appearance of the light emitting device closer to that of a conventional light bulb, but the installation may be omitted.

Next, the function of the lighting device according to the present invention configured as described above will be described. The base 1 has a function of fixing the lighting device and supplying an electric current. The terminal 4b of the drive board 4 has a contact point for directly connecting to the eyelet 1a of the base 1 and the terminal 4c to the shell 1b of the base 1. The substrate 4 electrically connected to the eyelet 1a of the base 1 and the shell 1b includes a drive circuit 4a for lighting the lead type LED 2. The lead type LED 2 receives power from the drive circuit 4a and emits light. The filler 5 has a function of protecting the contacts and electronic circuits provided on the substrate 4 from oxidation by the outside air and invasion of foreign substances, increasing the strength of the base, and enhancing the heat dissipation effect. The lid 6 has the effect of protecting the inside of the mouthpiece from foreign matter, preventing the internal parts and the inside of the mouthpiece from being seen, and enhancing the aesthetic appearance.

It can be said that the lighting device provided with the base of this embodiment is obtained by adding a pedestal 3 for positioning the light emitting element 2 to the lighting device of the first embodiment of Patent Document 2. This addition was made to solve the problem of Patent Document 2. The problems of Patent Document 2 are shown below.
The first problem is that since the filler 5 is filled between the light emitting element 2 and the base 3 to fix the light emitting element 2, the light emitting element 2 is stressed due to expansion or contraction during solidification of the filler 5. This is a problem that the position of the light emitting element 2 deviates from the target position after the filler 5 is solidified. Since the position of the light emitting element 2 was fixed by connecting the lead of the light emitting element 2 to the drive substrate 4, the position of the light emitting element 2 may be displaced due to such stress.
The second problem is that since the surface of the filler 5 after solidification is exposed as it is, if air bubbles or foreign substances enter the filler 5, the appearance is deteriorated.

As a solution to the first problem, it is necessary to securely fix the position of the light emitting element 2 so that it does not move with some stress before the filler 5 solidifies. Therefore, the pedestal 3 of the light emitting element 2 was developed, but some ingenuity was required to solve the following problems.
Various restrictions occur in order to use a substrate having a protrusion for directly connecting the end of the substrate to the base, which appears in Patent Document 2. The purpose of using this substrate is to avoid making electrical connections via conductors and reduce man-hours. That is, connecting the light emitting element and the substrate with a soft conducting wire so that the position of the light emitting element can be adjusted later is contrary to the object of the invention and should be avoided. Similarly, we also want to avoid connecting the board and the base with a soft wire.
The light emitting element 2 has its leads 2c directly fixed to the drive substrate 4, and the drive substrate 4 is electrically connected to the base 1 (by a method such as soldering, spot welding, or laser welding). Sometimes the lead type LED 2 is positioned. Therefore, in order to position the light emitting element, the light emitting element 2 must be installed on the pedestal 3 and the pedestal 3 must be inserted into the base 1 before the drive board 4 is connected to the base 1. The pedestal of the lead type LED 2 needs to form a connection portion with the base 1 leaving a working space so as not to interfere with the work of electrically connecting the drive board 4 to the base 1. Therefore, we devised a pedestal 3 having an arc-shaped portion in contact with the base 1 and a notch portion in which the portion is interrupted.
As a result, after the light emitting element 2 is reliably positioned, the substrate 4 and the base 1 can be electrically connected and the filler 5 can be solidified, and the problem of misalignment of the light emitting element 2 does not occur. It was.

The second problem is that in order to solve the first problem, there is a gap between the pedestal 3 and the base 1, and the appearance is deteriorated. In order to solve this problem, a lid 6 was devised. The lid 6 is provided with a hook 6a at a position corresponding to the notch 32b of the pedestal 3. The hook 6a can be assembled without being adhered by hooking it on the pedestal 3 by utilizing elasticity.

As another device, when the pedestal 3 is inserted into the base 1, the base of the arcuate portion 32a is made slightly larger than the inner diameter of the base 1 in order to position in the insertion direction, and a stopper structure 32d is provided. It was.
When the arcuate portion 32a of the pedestal 3 is crimped to the inner surface of the base 1, it receives a stress such that it is compressed toward the center of the base 1. If the shape of the arcuate portion 32a can be maintained against this stress, the frictional force between the pedestal 3 and the base 1 increases, and it becomes difficult for the pedestal 3 to come off the base 1. In order to counter this stress, a beam 32c for connecting the arcuate portions 32a to each other was provided. Furthermore, since the beam 32c is also made to be in contact with the inner surface of the base 1, compressive stress is applied relatively evenly to the arcuate portion 32a and the beam 32c, and the shape of the base 1 changes due to the influence of the insertion of the pedestal 3. I devised to minimize it.

In FIGS. 1 to 5, there are four notches in the portion to be inserted into the base of the pedestal, but the number may be changed depending on the situation.

FIG. 6 is a plan view of the first embodiment before fitting the lid 6 when the pedestal 3 has four notches 32b.
The center of each notch 32b divides the circumference equally at intervals of 90 °. The terminal 4c connected to the inside of the shell 1b of the drive board 4 is provided in the two notches 32b facing each other. In addition, the filler 5 can be injected through the other two notches 32b. When the filler 5 is injected, it does not interfere with the drive substrate 4, so that it is easy to inject. Further, when the filler 5 does not penetrate well into the back side of the injected surface, it can be injected from the back surface as well.

FIG. 7 is a plan view of the first embodiment before fitting the lid 6 when the notch 32b of the pedestal 3 is three.
The centers of each notch 32b are arranged at intervals of 120 °. The terminal 4c connected to the inside of the shell 1b of the drive board 4 is provided in one notch 32b. In addition, the filler 5 can be injected through the other two notches 32b. When the filler 5 is injected, it does not interfere with the drive substrate 4, so that it is easy to inject.

FIG. 8 is a plan view of the first embodiment before fitting the lid 6 when the pedestal 3 has two notches 32b.
The centers of each notch 32b are arranged at intervals of 180 °. In the two notches facing each other, terminals 4c connected to the caps at both ends of the drive board are provided. Further, the filler 5 can be injected through the notch 32b. The notch may be enlarged to facilitate injection of the filler 5.

FIG. 9 is a plan view of the first embodiment before fitting the lid 6 when the notch 32b of the pedestal 3 is one.
A terminal 4c for connecting to the base of the drive board 4 is provided in the notch 32b. Further, the filler 5 can be injected through the notch 32b. The notch 32b may be enlarged so that the filler 5 can be easily injected.

The number, position, size, and position of the connection point between the terminal 4c and the shell 1b in the pedestal 3 are merely examples, and other values can be taken depending on the purpose.
The left and right ends of the drive board 4 can be terminals 4c with the inside of the shell of the base 1, or if the drive board 4 to which the light emitting element 2 is connected is too wide to be inserted into the pedestal 3, the drive board 4 can be inserted. Only one end of 4 may be used as a contact point with the inside of the base 1, and one end may be formed small so as not to interfere with the arcuate portion 32a or the beam 32c of the pedestal 3.

Further, when the pedestal 3 is manufactured by using a resin as a material and molding using a mold, if the mold of the portion where the light emitting element of the pedestal 3 is installed has a nested structure, the combination of the molds can be used. , It is possible to correspond to the light emitting element 2 having various shapes. Moreover, since the mold for the outer portion of the pedestal 3 can be the same, it is possible to give diversity to the products at a relatively low cost.

Further, if the color of the pedestal 3 is the same and the lid 6 is colored with a color reminiscent of the emission color, the number of parts to be possessed can be significantly reduced as compared with the case where the pedestal 3 is colored.
For example, when it is necessary to prepare a product group having 3 types of light emitting elements 2 and 6 types of light emitting colors, and when the pedestal 3 alone supports all combinations of light emitting colors of the shape, 3 × 6 = 18 It is necessary to have an inventory of pedestals 3 of the type.
However, if the pedestal 3 is responsible for the variety of parts related to the shape of the light emitting element and the lid 6 is responsible for the variety of parts related to the emission color of the light emitting element, the pedestal 3 has three types and the lid 6 has six. If you have different types of inventory, you can handle all combinations, and even when you have a variety of product lineups, you can reduce the inventory of parts.

FIG. 10 is an assembly drawing when the driving device of the lighting device according to the first embodiment of the present invention is a lead type component.
As shown in FIG. 10, the lighting device of the present invention can be configured by replacing the substrate with a lead-type component. When composed of lead-type parts, the plasticity of the lead is utilized, and the light emitting element 2, the pedestal 3, and the lead-type part are assembled and electrically connected to the inside of the shell 1b to the base 1, and then connected to the base 1. Can be inserted. At this time, if the beam 32c of the base insertion portion of the pedestal 3 interferes and is difficult to insert, the pedestal 3 without the beam 32c may be used.

As shown in FIG. 11, a cover 7 that covers the light emitting element 2 may be provided. By providing the cover 7, there are effects such as making the appearance of the lighting device of the present invention closer to the appearance of a conventional light bulb, controlling the emitted light such as deflection, focusing, and diffusion, and making it easier to hold by hand. ..

The manufacturing process of the lighting apparatus of the first embodiment will be described with reference to FIGS. 1, 3 and 5.
The light emitting element 2 is soldered to the drive substrate 4. The light emitting element 2 to which the drive board 4 is attached is inserted into the pedestal 3. At this time, the collar 2b of the light emitting element hits the narrowed portion provided inside the through hole 31 which is the light emitting element installation portion of the pedestal 3, and the light emitting element 2 is positioned. Further, the terminal 4c with the shell of the base of the drive board 4 is exposed from the notch 32b of the base insertion portion of the pedestal 3.

Next, the pedestal 3 to which the light emitting element 2 is attached is inserted into the base 1. The arcuate portion 32a of the base 3 insertion portion of the base 3 contacts the inside of the base 1 and acts as a guide, and determines the position of the light emitting element 2 with respect to the central axis of the base 1. Further, the stopper 32d provided at the base of the arcuate portion 32a determines the position of the light emitting element 2 with respect to the height direction of the base 1. By these two positionings, the positioning of the light emitting element 2 with respect to the base 1 is completed.

At this time, the terminal 4b with the eyelet provided at the lower part of the drive board 4 is exposed from the eyelet 1a of the base 1. If the contact provided on the terminal 4b and the eyelet 1a of the base 1 are soldered, the eyelet 1a and the drive board 4 are electrically connected. Further, in order to secure the electrical connection of the shell 1b, the terminal 4c with the shell 1b provided on the side of the drive board 4 and the inner surface of the shell 1b are soldered.

Next, the filler 5 is poured into the gap between the base 1 and the pedestal 3 of the light emitting element portion to be fixed. The filler 5 can be poured through the notch 32b of the base insertion portion of the pedestal 3. In the case of this embodiment, the notches 32b are prepared at four places and are arranged in a cross shape. The terminal 4c of the drive board 4 with the shell is inserted into two notches 32b facing each other, and the remaining two notches 32b are arranged at positions perpendicular to the drive board 4. When the filler 5 is injected into the base 1, it is easy to inject the filler 5 through the notch 32b arranged in the direction perpendicular to the drive substrate 4. The filler 5 has the effect of protecting the parts from oxidation and the invasion of foreign substances and promoting heat dissipation, but it may not be used when it is unnecessary.

Finally, a lid 6 for hiding the inside of the base 1 and foreign matter of air bubbles in the filler 5 is attached. The lid 6 has an annular shape, and can be fitted into the cylindrical portion of the light emitting element installation portion of the pedestal 3 like a ring.
A hook 6a is prepared inside the lid 6, and the hook 6a can be fixed by hooking the hook 6a on the notch 32b of the pedestal 3. In the case of FIG. 4 of this embodiment, four notches 32b are prepared and arranged in a cross shape. There are also four hooks. As a result, the annular lid 6 can be attached without distortion.

As described in detail above, the lighting device according to the present invention according to the present embodiment can be assembled by reliably positioning the light emitting element 1 without using a conducting wire.
Further, it is possible to cope with the case where the drive unit of the light emitting element is a lead type component.

The second embodiment is a lighting device including a base in which a light emitting element is installed from the outside of a pedestal and the light emitting element and a driving device are connected to each other on the outside of the base.

FIG. 18 is a perspective view of the pedestal of the second embodiment of the present invention as viewed from the base insertion direction.
FIG. 19 is an internal structural view of the lighting device according to the second embodiment of the present invention as viewed from diagonally above.

FIG. 21 is a cross-sectional view of the lighting device according to the second embodiment of the present invention as viewed from the front side of the substrate.

As shown in FIG. 17, the lighting device provided with this base includes a base 1 having a fixing function to an appliance and a power feeding function, a surface-mounted LED element 2 as an example of a light emitting element, and a surface-mounted LED element. A drive board 4 provided with an installed light emitting element substrate 2d, a pedestal 3 of a light emitting element having a light emitting element installation portion 31 and a base insertion portion 32, and a terminal portion 4c connected to the inside of the shell of the base 1 of the base 1. The LED drive circuit 4a provided on the drive substrate 4 and the filler 5 filled inside the base 1 are provided.

The pedestal 3 has an original shape in order to cope with the problem to be solved.
The light emitting element installation unit 31 is provided with a recess for inserting the light emitting element unit 2 in which the surface mountable LED 2a is installed on the light emitting element substrate 2d from below. The bottom of the recess and the light emitting element substrate 2d come into contact with each other to position the light emitting element 2.

Next, the function of the lighting device according to the present invention configured as described above will be described. The base 1 has a function of fixing the lighting device and supplying an electric current. The terminal 4b of the drive board 4 has an eyelet 1a of the base 1, the terminal 4c has a shell 1b of the base 1, and the terminal 4d has a contact that directly connects to the light emitting element board 2d. The drive board 4 electrically connected to the eyelet 1a of the base 1 and the shell 1b includes a drive circuit 4a for lighting the lead type LED 2. The lead type LED 2 receives power from the drive circuit 4a and emits light. The filler 5 has a function of protecting the contacts and electronic circuits provided on the substrate 4 from oxidation by the outside air and invasion of foreign substances, increasing the strength of the base, and enhancing the heat dissipation effect.

It can be said that the lighting device provided with the base of this embodiment is obtained by adding a pedestal 3 for positioning the light emitting element 2 to the lighting device of the first embodiment of Patent Document 2. This addition was made to solve the problem of Patent Document 2. The problems of Patent Document 2 are shown below.
The first problem is that since the filler 5 is filled between the light emitting element 2 and the base 3 to fix the light emitting element 2, the light emitting element 2 is stressed due to expansion or contraction during solidification of the filler 5. This is a problem that the position of the light emitting element 2 deviates from the target position after the filler 5 is solidified. Since the position of the light emitting element 2 was fixed by connecting the lead of the light emitting element 2 to the drive substrate 4, the position of the light emitting element 2 may be displaced due to such stress.
The second problem is that since the surface of the filler 5 after solidification is exposed as it is, if air bubbles or foreign substances enter the filler 5, the appearance is deteriorated.
The third problem is that the surface-mounted LED may generate more heat than the lead-type LED, and heat dissipation becomes a problem.

As a solution to the first problem, it is necessary to securely fix the position of the light emitting element 2 so that it does not move with some stress before the filler 5 solidifies. Therefore, the pedestal 3 of the light emitting element 2 was developed, but some ingenuity was required to solve the following problems.
In order to use the drive board 4 having a terminal for directly connecting the end of the board to the base 1 which appears in Patent Document 2, various restrictions occur. The purpose of using the drive board 4 is to avoid making an electrical connection via a conducting wire and to reduce man-hours. That is, connecting the light emitting element 2 and the drive substrate with a soft conducting wire so that the position of the light emitting element 2 can be adjusted later is contrary to the object of the invention and should be avoided as much as possible. Similarly, we also want to avoid connecting the board and the base with a soft wire.
The light emitting element (surface mount type LED) 2a is fixed via the light emitting element substrate 2d. The light emitting element substrate referred to here is an electronic circuit board made of a metal such as aluminum, a resin such as glass epoxy or bakelite, or the like. The surface-mounted LED does not have a lead 2c like a lead type LED, and is connected via an electrode provided on a light emitting element substrate. The electrode in this case is an electrode in which the metal foil attached on the substrate is exposed.
The basic idea is the same as that of the first embodiment, but the design is also different because the shape of the light emitting element to be driven is different.
The light emitting element substrate 2d provided with the surface mount LED 2a is easy to assemble on the premise that a recess serving as a guide is provided on the upper portion of the pedestal 3 and the light emitting element substrate 2d is installed in the recess.

As a solution to the second problem, there is a method in which the diameter of the light emitting element installation portion of the pedestal 3 is made larger than the diameter of the base 1 to cover the opening of the base 1. Since the pedestal 3 of the second embodiment is inserted into the base 1 after the drive board 4 and the base 1 are electrically connected, a gap between the pedestal 3 and the base 1 as in the first embodiment is necessary. Absent.
However, this does not apply when there is another purpose and it is necessary to provide a gap between the pedestal 3 and the base 1.

As a solution to the third problem, there is a method in which the substrate on which the surface-mounted LED is installed is made of a metal such as aluminum or is made as thin as possible. Further, the pedestal of the light emitting element may also be made of a metal such as aluminum. As a countermeasure against heat generation, it is effective to arrange the substrate provided with the surface-mounted LED so as to be in contact with a member made of metal or the like, so that the above structure is rational.

When the light emitting element portion 2 in which the surface mount LED 2a is installed on the light emitting element substrate 2d is installed in the recessed upper part of the pedestal 3 of the light emitting element 2, the pedestal 3 is used to electrically connect the light emitting element substrate 2d and the drive substrate 4. It is necessary to make a through hole in the bottom of the recess at the top of the device to secure a path for inserting the conductor. In this example, two through holes were drilled. If the pedestal 3 is made of metal and continuity with the shell 1b of the base 1 can be ensured, and one pole of the light emitting element substrate may be conductive with the shell portion of the base, the pedestal 3 itself can be used for conduction. In some cases, one hole is sufficient. The pedestal in this case is shown in FIG.
When the pedestal 3 has the above-mentioned structure, if a columnar elongated terminal 4d is provided on the upper part of the drive board 4 to form a conduction path, a lead wire or the like becomes unnecessary, and the assembly man-hours can be reduced. This elongated terminal is a protrusion 7 of Patent Document 2.

The manufacturing process of the lighting apparatus of the second embodiment will be described with reference to FIGS. 17, 19, and 21.
Unlike the first embodiment, the light emitting element unit 2 in which the surface mount LED 2a is installed on the light emitting element substrate 2d does not need to be connected to the drive substrate 4 in advance. Therefore, the drive board 4 can be inserted into the base 1 first and electrically connected (soldered) to the base 1.

In order to position the light emitting element 2, it is necessary to install the light emitting element portion 2 on which the surface mount LED 2a is mounted on the pedestal 3 and insert the pedestal 3 into the base 1. The pedestal 3 needs to be prevented from interfering with the electrical connection between the drive board 4 and the base 1. Therefore, a pedestal 3 having an arc-shaped portion 32a in contact with the base 1 and a notch 32b was devised.

When the drive board 4 is inserted into the base 1, the width of the drive board 4 is made slightly smaller than the inner diameter of the base 1, so that the drive board 4 functions as a guide and the drive board 4 can be arranged at the center of the base 1. In this state, the drive board 4 and the base 1 are electrically connected. At this time, the drive board 4 is also positioned.

FIG. 22 is a perspective view of the pedestal of the second embodiment of the present invention when there are three holes in the light emitting element installation portion.
When the filler 5 is injected into the base 1, the filler 5 may be injected before the pedestal 3 is inserted, or the pedestal 3 may be inserted and then the through hole provided at the bottom of the recess of the pedestal 3. The filler 5 may be injected from. It is possible to inject the filler 5 from the hole through which the columnar terminal 4d of the drive board 4 passes, but if the columnar terminal 4d is an obstacle, a hole dedicated to injecting the filler 5 is provided and filled from here. Material 5 may be injected. The pedestal in this case is shown in FIG.

FIG. 23 is a perspective view of the pedestal of the second embodiment of the present invention when there is only one hole in the light emitting element installation portion.
The pedestal may have only one hole in the light emitting element installation portion. An electrode to be fed to the light emitting element substrate may be ejected from one hole, and the filler 5 may be injected. In this case, the hole may be made slightly larger. If there is only one hole, opening it in the center simplifies the manufacturing process and leads to cost reduction. The pedestal in this case is shown in FIG.

When the pedestal 3 is inserted into the base 1, the terminal 4d of the drive substrate 4 is exposed from the through hole of the recess of the pedestal 3, so that the terminal 4d passes through the hole of the light emitting element substrate 2d. Is installed in the recess of the pedestal. At this time, it may be fixed with an adhesive.

The filler 5 determines the timing of curing according to its characteristics. It may be cured before the installation of the light emitting element unit 2 or may be cured after the installation of the light emitting element unit 2.

FIG. 24 is a perspective view when the width of the light emitting element portion of the pedestal of the second embodiment of the present invention is smaller than the diameter of the base.
When the width of the light emitting element portion of the pedestal is made smaller than the diameter of the base as shown in FIG. 24, the lid can be provided as in the first embodiment. This is convenient when you want to have the function of a cover or mirror.

FIG. 25 is a cross-sectional view of the pedestal of the second embodiment of the present invention in the case where the light emitting element installation portion is convex.
By doing so, the pedestal can be brought closer to a position close to the light emitting element of the light emitting element portion, so that it can be expected that the heat dissipation effect will be enhanced when the pedestal is made of metal or the like.

FIG. 26 is a cross-sectional view of the pedestal of the second embodiment of the present invention when the light emitting element installation portion is flat.
In this way, processing becomes easy, and cost reduction can be expected.

FIG. 27 is a cross-sectional view of the case where the light emitting element of the lighting device according to the second embodiment of the present invention is a surface-mounted LED and is directly connected to the pedestal.
In this way, the light emitting element substrate of the light emitting element portion can be omitted, so that cost reduction and the like can be expected. Further, when the pedestal is made of metal, the heat dissipation effect can be expected to be high.

FIG. 28 is a perspective view in the case where the light emitting element of the lighting device according to the second embodiment of the present invention is an LED chip and is directly connected to the pedestal.
The method of connection is wire bonding. In this way, the process of sealing the LED can be carried out as it is on the pedestal, so that the process of sealing the LED and the process of connecting the light emitting element portion to the pedestal can be integrated, and the cost can be reduced. You can expect it. Further, when the pedestal is made of metal, the heat dissipation effect can be expected to be high.

Even in this case, the pedestal 3 having the structure peculiar to the present invention can be used and assembled by using the structure and the manufacturing method described above. That is, the case where the lead type feeding unit 4 is used as a driving device for a light emitting element is also included in the claims of the present invention.
