Description

  The present invention relates to an LED socket and an LED socket structure including the LED socket, an LED lighting device, and an LED lamp.

  As a configuration for supporting a base substrate on which an LED socket is provided with a light emitting unit (LED), there is known one comprising upper and lower two holders, and holding the base substrate by these holders and fixing them with a clip or the like. Non-Patent Document 1 discloses an LED socket configured as described above. FIG. 17 is a view showing an example of a conventional LED socket, and is a perspective view showing such a configuration. The LED socket 1700 shown in this figure comprises two members, a lower holder 1701 and an annular upper holder 1702 rotatably fixed thereto. Then, when mounting the base substrate 1711 in the LED socket, as shown in (a), the base substrate is mounted on the lower holder, and the electric wire 1720 is mounted from above the upper holder ( Although it does not appear in the figure, the feed terminal attached to the end of the wire is fixed at the back surface position of the base substrate 1711 in contact with the feed pad 1713) Fix with a clip etc. (B) shows a state where the base substrate is attached to the LED socket and fixed by the clip 1750 with such a configuration (see Non-Patent Document 1).

  By the way, there is also a case where the work of mounting the base substrate having the light emitting part arranged therein to the LED socket should be performed in an unreasonable posture such as supine in a place where the scaffold is unstable such as exchange work near the ceiling. In this respect, in the case of the configuration like the LED socket disclosed in Non-Patent Document 1, these members are used to hold the LED substrate between the upper and lower holders at the work site and fix them with a plurality of clips or the like. There is a problem that it is difficult to work while holding the head with both hands surely, for example, errors such as dropping a clip or the like are likely to occur. Moreover, in the case of such a configuration, it is difficult to position the base substrate when sandwiching it, and there is also a problem that the base substrate can not be easily attached to the socket.

  On the other hand, there is also known an LED socket provided with means for pressing the base substrate horizontally from the periphery to the center to support it. For example, Patent Document 1 describes an LED socket including a plurality of positioning members. The positioning member is disposed around the base substrate (LED printed circuit board). It is described that a leaf spring-like interface is provided at the tip of the positioning member, and this interface is in contact with the side surface of the base substrate, and the base substrate is pressed and supported by the biasing force toward the center of the base substrate. 1, especially see Figure 1 etc.). With such a configuration, the base substrate can be supported so as not to fall off in a manner so to say as it is temporarily fixed to the LED socket at the time of work in the field, so one of the members is lowered at the time of replacement work near the ceiling. It is thought that the problem that mistakes such as being dropped may easily occur is improved. Further, since the positioning member facilitates the positioning of the base substrate, the problem of the configuration as described in Non-Patent Document 1 can be improved also in that the base substrate can be easily attached to the socket. It has become.

<Overview>
The LED socket of this embodiment has an annular shape, and a cantilever elastic support that supports the LED receiving structure for supporting the LED structure and the side surface of the base substrate of the LED structure with a cantilever structure. It is characterized in that it has a part. In addition, an LED socket structure including such an LED socket, an LED lighting device, and an LED lamp are also included in this embodiment.

<Configuration>
(General)
The LED socket is for supporting the LED structure. FIG. 1 is a view showing an outline of the LED socket of this embodiment, and shows an LED socket structure 0150 in which the LED structure 0110 is mounted on the LED socket 0100. As shown in FIG. That is, the LED socket structure in a present Example arrange | positions a LED structure to a LED socket. Among these, (a) is a perspective view seen from the light emitting surface 0112 side of the LED, and (b) is a perspective view seen from the back surface side of the light emitting surface of the LED. FIG. 2 is an exploded perspective view of FIG. 1, and (a) and (b) of FIG. 2 correspond to (a) and (b) of FIG. 1, respectively. Hereinafter, for convenience, the same surface side as the light emitting surface of the LED structure of the LED socket shown in FIG. 1 and FIG. 2A will be described as the front side, and the side shown in FIG.

  When the LED is used for light emission, it may be used as an LED lighting apparatus in which the LED socket structure is further disposed in the lamp, in addition to the case of using the LED socket structure as shown in FIG. Alternatively, the LED socket structure may be used as an LED lamp disposed in the LED lamp body. FIG. 3 is a view showing an example of the configuration of the LED lighting apparatus and the like of this embodiment, wherein (a) is a lighting apparatus 0380 in which the LED socket structure 0350 is disposed on the lamp 0360, (b) is an LED socket structure The LED lamp 0390 which has arrange | positioned 0350 to the LED lamp main body 0370 (provided with the cover 0371, the thermal radiation part 0372, and the nozzle | cap | die 0373) is shown.

(LED structure)
In FIG. 2, the LED structure 0210 includes a base substrate 0211, a light emitting unit 0212, a feed pad 0213, and a support unit 0214. The light emitting unit is disposed on the base substrate and has an LED element. The feed pads are for receiving the supply of external power through the feed terminals provided at the ends of the wires connected to the external power supply, and are generally arranged at two locations on the base substrate (also the feed pads in this figure). Such an example). The support portion is a portion of the base substrate excluding the light emitting portion and the feed pad on the base substrate, and is a portion supported by the LED socket. The details of the support will be described together with the configuration of the LED socket described later.

  When mounting the LED structure in the LED socket, as shown in FIG. 2, with the light emitting surface of the LED structure facing front, the LED structure is fitted from the back to the opening 0203 of the LED socket 0200. Put on.

  As the material of the base substrate, a ceramic such as aluminum oxide or aluminum nitride, a resin such as epoxy resin or silicone resin, or a metal such as aluminum or stainless steel is used. Alternatively, these materials may be combined. Ceramics are generally excellent in insulation and heat resistance, and resins are generally excellent in elasticity and easy to be processed. However, they also have a problem that they have relatively low strength compared to metals. In the LED socket of the present invention, for example, the material of the base substrate is relatively lower in strength than the material of the LED socket and broken as in the case where the material of the LED socket is metal and the material of the base substrate is ceramic or resin. It is especially effective when it is easy.

(LED socket)
Next, the configuration of the LED socket will be described. FIG. 4 is a view showing an example of the configuration of the LED socket of the present embodiment, and is a view of the LED socket as viewed from the front side. This figure shows the LED socket in a state in which the LED structure has been removed from the state shown in FIG. 1 (a). As shown in the drawing, the LED socket 0400 of this embodiment is an annular member having an opening 0403 penetrating substantially at the center, and has a bearing receiving portion and a cantilever elastic supporting portion. In the example of this figure, the bearing receiving part is provided in three places (indicated by oblique lines 0401a and 0401d, 0401b and 0401e, 0401c and 0401f) at six places, and one pair of cantilever elastic supporting parts (0402a and 0402b) Is provided). FIG. 5 is a view showing an example of the configuration of the LED socket of this embodiment, and is a view of the LED socket as viewed from the back side.

  In addition, as shown in FIG. 4, the LED socket of the present embodiment may be provided with screw holes 0405 for fixing the LED socket itself to the lamp or the LED lamp main body. Further, although not shown in FIG. 4, a wire fixing portion (for example, a protrusion provided with a wire insertion hole) for fixing the wire may be provided, and in this case, the mounting of the LED structure It is possible to turn on the current immediately to light the LED for use.

(Support bearing)
The bearing support is configured to support all or part of the bearing of the LED structure. In the present invention, "supporting" refers to supporting the LED structure so as not to drop from the LED socket in the front and back direction without using other members, that is, only by contact with the LED socket.

  FIG. 6 is a diagram for describing the configuration of the bearing receiving portion, and is a cross-sectional view taken along the line A-A of FIG. 1 (however, it is a conceptual diagram for explanation. ). In the example of this figure, the bearing receiving part 0601 (the range indicated by the oblique lines in general) of the LED socket 0600 is the light emitting surface side (in the figure) the light emitting part 0612 is the bearing area 0614 (the area indicated by the oblique lines) of the LED structure 0610 Support from above). With such a structure, when the LED structure is attached to the LED socket from the back side (the lower side in the figure) of the light emitting surface, the LED structure is restricted by the bearing receiving portion and stops at this position. The LED structure can be easily mounted by one touch without worrying about pushing too much.

  Also, in general, the LED socket in a state in which the LED structure is mounted is used by being fixed to a lamp, an LED lamp main body, etc. by screwing or the like. Therefore, at the time of such use, the LED structure is supported so as not to come off by being pinched between the lamp and the like and the support receiving portion. Thus, the bearing receiver also has the function of fixing the LED structure after mounting (in use).

  The specific shape, size, arrangement position of the bearing support and the position where this is provided means that the LED structure can be supported without falling off and that the thermally expanded LED structure is not broken or the like. To be properly designed. For example, as an example of a preferred arrangement, it can be considered that at least a part of the bearing receiver is arranged adjacent to the cantilever elastic support (details will be described later in another embodiment).

(Cantilever elastic support)
The cantilever elastic support is configured to laterally elastically support the side surface of the base substrate of the LED structure with a cantilever structure. The cantilever beam structure refers to a beam structure in which one end is fixed and the other end is free. In the example shown in FIG. 4, one end of the cantilever elastic support 0402a (generally indicated by hatching 0402a1) is fixed to the main body of the LED socket, and the other end (generally indicated by hatching 0402a2) is free. It is the end. The term "lateral elastic support" refers to elastic support from the side of the base substrate by a biasing force.

  FIG. 7 is a view showing an example of the shape of the cantilever elastic support. As shown in the figure, the cantilever elastic support portion 0702 has a contact portion 0706 which is a portion provided with a contact surface 0706a which is in contact with the base substrate directly and elastically supports the same, and a contact portion support portion supporting the contact portion. And 0707. The cantilever elastic support has a shape in which the free end of the contact surface protrudes slightly toward the center of the arrangement surface of the LED structure (in the direction of arrow A in the figure) compared to the fixed end, and the fixed end of the contact surface The side has a shape protruding toward the center of the arrangement surface of the LED structure with respect to the contact portion supporting portion, and the contact surface has a shape corresponding to the side shape of the base substrate (for example, linear shape if the base substrate is square) Is desirable. As a result, when the LED structure is mounted, the entire surface of the contact surface of the cantilever elastic support portion can be in contact with the base substrate and pressed by the biasing force, and the base substrate can be firmly elastically supported on the side. Become.

  As the contact method of the cantilever elastic support portion and the side surface of the base substrate, (1) almost the entire contact surface of the cantilever elastic support portion contacts the side surface of the base substrate in the normal temperature state (state without thermal expansion of the base substrate) And (2) in the normal temperature state, only one of the contact surfaces of the cantilever elastic supporting portion contacts the side surface of the base substrate, and the high temperature state (the base substrate is thermally expanded) At this time, it is conceivable that substantially the entire contact surface of the cantilever elastic support portion contacts the side surface of the base substrate. Although this embodiment includes both contact methods, (2) is better in that heat transfer can be more suitably performed in a high temperature state.

  FIG. 8 is a diagram for describing the configuration of the cantilever elastic support. Among these, FIG. 8 (a) is an end view taken along the line B-B of FIG. 1 (a). In the example of this figure, the cantilever elastic support portion 0802 of the LED socket 0800 supports the side surface 0811a of the base substrate 0811 of the LED structure by the biasing force from the side toward the base substrate central direction (arrow A direction in the figure). doing.

  In order to exert a biasing force from the cantilever elastic support portion to the base substrate when the base substrate is attached, the cantilever elastic support portion is slightly expanded in the outer peripheral direction of the base substrate when the base substrate is attached compared to before the base substrate attachment. Need to be In other words, in the LED socket prior to mounting of the base substrate, the cantilever elastic supporting portion projects slightly inward from the virtual side position at the time of mounting of the base substrate. FIG. 8B is a view showing the state of the cantilever elastic support portion 0802a before mounting the base substrate. This figure is an end view cut in a direction horizontal to the base substrate surface within the range of the thickness (height) of the base substrate (for example, the position of the X-X line in FIG. 8A). It shows only the state near the part. In the drawing, a state in which the substrate slightly protrudes in the center substrate direction (arrow A direction) from the imaginary side surface 0811 a when the base substrate is attached. FIG. 8C shows the state of the base substrate side surface 0811b and the cantilever elastic support portion 0802b (shown by a solid line) when the base substrate is attached, and the cantilever elastic support portion 0802a (broken line) before the base substrate is attached. A state is shown in which the base substrate is slightly expanded in the peripheral direction of the base substrate (in the direction of arrow B) than (shown in FIG. 8) (note that FIGS. 8B and 8C are drawn exaggerated for the convenience of description). ).

(Contact between LED socket and base board)
Next, the contact state of the LED socket and the base substrate in the present embodiment will be described. In this case, when the LED structure is disposed in the LED socket among the inner side surfaces in the thickness direction of the LED socket, the inner side surface facing the end face of the base substrate of the LED structure, It is desirable to design the LED socket so that the relationship between the inner surface excluding the side elastic support surface (hereinafter referred to as “opposite inner surface”) and the end surface of the base substrate of the LED structure does not become close.

  FIG. 9 is a conceptual view showing the opposite inner side. A portion indicated by hatching 0900a is the opposing inner side surface, and is formed in a substantially square shape as a whole according to the shape of the base substrate. In the drawing, the upper side is the front side of the LED socket, and the bearing receiving portion disposed near the surface is indicated by a broken line 0901. Further, the “close state” refers to a state in which the opposing inner side surfaces closely surround the base substrate and there is no room for the base substrate to move in a direction parallel to the substrate surface.

  Specifically, when supporting the LED structure, the portion where the LED socket is in direct contact with the base substrate is only the cantilever elastic support portion, and the opposing inner side surface is not directly in contact with the side surface of the base substrate. Is desirable. Alternatively, even if the side surface of the base substrate is in contact with a part of the opposite inner side surface, the opposite inner side surface does not tightly surround the base substrate, and the base substrate has room to move in a direction parallel to the substrate surface. , Not included in the above-mentioned close state.

  FIG. 10 is a view showing an example in which the relationship between the opposing inner side surface and the end surface of the base substrate is not in close contact. Among these, (a) shows an example in which the opposing inner side surface 1000 a and the base substrate side surface 1011 are not in contact at all. The opposite inner side surface is cut at the middle portion between the upper side and the lower side because the cantilever elastic support portion is disposed here. (B) and (c) are examples in which the opposing inner side and the base substrate side are in contact. Among them, (b) is an example in which one surface of the side surface of the base substrate is in contact with the opposing inner surface (a surface that is not the same surface as the cantilever elastic support and appears on the left side in this figure). It is. Contrary to this figure, the one in which one side of the base substrate side is in contact with the right side of the opposite inner side is also included in this example. (C) is in contact with the opposing inner side where the two corners of the side of the base substrate face each other (right and left sides which are not the same plane as the cantilever elastic support in this figure) Is an example not in contact. Unlike in this figure, the example in which two corners of the side surface of the base substrate are in contact with the opposite inner side surface which is the same surface as the cantilever elastic support portion is included in this example. The base substrates are preferably arranged point-symmetrically with respect to the center of the space surrounded by the opposing inner side surfaces, and the figures (a) and (c) are such preferred examples.

  The significance of this configuration is as follows. When the base substrate is thermally expanded, the cantilevered elastic supporting portion supporting the same from the side is hardly displaced near its fixed end, and is displaced largely as it approaches the free end. When the base substrate expands, the cantilever elastic support is displaced accordingly. FIG. 11 is a conceptual diagram for explaining an example of the contact state between the cantilever elastic support and the base substrate, in which (a) is a state before thermal expansion of the base substrate 1111, and is a side surface of the base substrate. 1111a is supported in contact with the cantilever elastic support portion 1102, but there is a gap between it and the opposing inner side surface 1100a. In (b), the base substrate is in a thermally expanded state, and the base substrate is at two points near the fixed end of the cantilever elastic support (only one point O near the fixed end of one cantilever elastic support in FIG. In the opposite position, there is one point near the fixed end of the other cantilever elastic support (not shown), and it rotates in the arrow C direction. In (b), the solid line 1111b indicates the position of the base substrate side surface after rotation, and the dashed line 1111a indicates the position of the base substrate side surface before rotation. At this time, since there is a gap between the base substrate and the opposing inner side surface 1100a, when the base substrate is rotated due to thermal expansion, there is a margin for rotating until the base substrate abuts against the opposing inner side surface (FIG. The base substrate is shown in contact with the opposite inner side at the position indicated by arrow A). For this reason, even when the base substrate is thermally expanded, there is almost no change in the pressing force that the base substrate receives from the LED socket, and the possibility that the LED structure is broken or a malfunction is largely eliminated.

(Others)
The shape of the ring formed at the center of the LED socket is preferably close to the shape of the LED structure so that the LED structure can be easily fitted. At that time, in order to make it easy to grasp the correct orientation in which the LED structure is fitted, the shape of the ring and the shape of the LED structure almost identical to this are mounted even if trying to fit the LED structure 90 degrees apart For example, the shape may be a substantially rectangular shape or a substantially elliptical shape. Further, as shown in FIG. 4, the LED socket is provided with notches 0404 (three places in this figure for exposing the side surface of the base substrate) in order to facilitate the removal operation of the LED structure. In order to avoid complication, only one reference numeral may be provided. In this case, it is possible to easily remove the LED structure from the LED socket by, for example, bringing the removal tool into contact with the side surface of the base substrate exposed in the notch and drawing out the base substrate using frictional force.

<Effect>
According to the invention of this embodiment, the LED socket can be easily mounted on the LED socket without dropping parts even in a difficult work site such as near a ceiling, which is an LED It is possible to provide an LED socket that does not have the risk of destroying the LED structure or causing functional failure even if the structure thermally expands.

<Overview>
The LED socket of the present embodiment is basically in common with the first embodiment, but is further characterized in that the LED socket is composed of upper and lower two halves. However, unlike the conventional case in which the LED structure is sandwiched between two separated halves and fixed by a clip or the like, the two halves are assembled from the beginning. Therefore, the point that the mounting of the LED structure can be performed only by fitting it into the single-piece LED socket is the same as in the case of the first embodiment.

<Configuration>
FIG. 12 is a view showing an example of the configuration of the LED socket of this embodiment, and shows a state in which the LED structure 1210 is attached to the LED socket 1200 to which the electric wire 1220 is attached. Among these, (a) is a perspective view seen from the light emitting surface side of the LED, and (b) is a perspective view seen from the back surface side of the light emitting surface. As shown in this figure, in the LED socket of this embodiment, the first half 1230 and the second half 1240 are overlapped and clips 1250 (four are provided in this figure, but one place to avoid complication) (With a symbol attached to only).

  The first half may have basically the same structure as the LED socket of the first embodiment. The example shown in this figure is also such an example, and as shown in (b), the first half body has the bearing receiving portion 1231 and the cantilever elastic supporting portion 1232 (even in the example of this figure, Three pairs of reception units are provided, but some do not appear in the figure). The second half is an annular member having substantially the same outer shape as the first half and does not appear in the figure, but the terminal receiving portion and the wire for mounting the terminal provided at the tip of the wire are It is desirable to have a guide groove for sandwiching and fixing between one half body. In addition, a convex part is provided in the surface of one half of the mutually contacting surfaces of both halves for positioning at the time of superposing a first half and a second half, and the surface of the other half There may be provided a recess at the corresponding position of which the protrusion can be inserted exactly. FIG. 13 is a view showing an example of the shape of the back surface (the surface on the side in contact with the first half) of the second half 1360, and the terminal receiving portion 1361, the guide groove 1362, and the recess 1363 for positioning are shown. An example is provided. By being configured as described above, the LED socket of the present embodiment can hold the electric wire more firmly. Moreover, it becomes possible to make it light-emit and use it, making it supply with electricity immediately at the time of mounting | wearing of a LED structure.

  Since the material of the first half is provided with a cantilever elastic support and also serves as a heat sink, it is desirable that the material has a certain degree of elasticity and high heat dissipation in addition to durability, for example, epoxy resin, silicone resin It is conceivable to use a resin such as On the other hand, since the material of the second half is provided with the terminal receiving portion, it is desirable that the material has excellent insulation properties in addition to the durability. For example, it is conceivable to use a ceramic such as aluminum oxide or aluminum nitride . By making the LED socket consist of two halves in this way, the material of each half can be made different to suit each function.

<Effect>
According to the invention of this embodiment, the wire can be held more firmly, and the material of the portion provided with the cantilever elastic supporting portion and the portion provided with the terminal receiving portion are made different according to their functions. Can.

<Overview>
In the LED socket of the present embodiment, the bearing receiving portion is provided at a point symmetrical position with respect to the center of the LED arrangement plane when the space in which the LED structure is arranged is viewed in plan from the LED light emitting surface side is there.

<Configuration>
(Support bearing: point symmetrical position)
The LED socket of this embodiment is basically in common with the LED socket of the first or second embodiment. However, in the LED socket of this embodiment, the bearing receiving portion is provided point-symmetrically to the center of the LED arrangement plane when the space in which the LED structure is disposed is viewed in plan from the LED light emitting surface side. It is characterized by The significance of this configuration is that the support of the base substrate by the bearing support can be more properly performed. That is, the function of the bearing receiver is to firmly support the base substrate when the base substrate is rotated by friction with the bearing receiver as the thermal expansion is performed, but the bearing receiver is thus configured of the LED Being arranged point-symmetrically with respect to the center of the plane, the base substrate can be rotated while maintaining point symmetry in the opposing inner side when the base substrate is rotated, whereby the base substrate and the bearing support can be rotated. The friction between the parts occurs uniformly throughout, allowing the base substrate to be properly supported by the bearing support.

  Furthermore, on the premise that the light emitting portion is disposed substantially at the center of the base substrate, the heat dissipation from the LED is caused by the support receiving portion being thus point-symmetrical with respect to the center of the LED arrangement plane. There is a significance that the heat transfer accompanying with can be performed equally. That is, with such an arrangement, even when the base substrate thermally expands with light emission and the base substrate moves in the opposing inner side surface, the base substrate moves while maintaining the point-symmetrical arrangement in the opposing inner side surface. It becomes possible. The heat transfer from the base substrate to the LED socket takes place via the bearing receiver which is in most contact with the base substrate, thus the bearing receiver is arranged point-symmetrically to the center of the LED placement plane As a result, the heat from the light emitting portion can be uniformly transmitted to the base substrate, and the heat can be uniformly transmitted from the base substrate to the bearing receiving portion, so that the heat radiation effect can be improved.

  FIG. 14 illustrates an example of a state in which the support receiving portion is arranged point-symmetrically with respect to the center of the LED arrangement plane when the space in which the LED structure is arranged is viewed in plan from the LED light emitting surface side. FIG. 6 is a plan view of the LED socket. In the example of this figure, three pairs of bearing receivers are provided at positions symmetrical with respect to the center 1415 of the LED arrangement plane. That is, the bearing receiving portion 1401a and the bearing receiving portion 1401d are a pair, the bearing receiving portion 1401b and the bearing receiving portion 1401e are a pair, the bearing receiving portion 1401c and the bearing receiving portion 1401f are a pair, and each pair is an LED arrangement plane The point is symmetrical with respect to the center of the

<Effect>
According to the invention of this embodiment, the base substrate can be supported more appropriately, and the heat transfer accompanying the heat radiation from the LED can be performed evenly.

<Overview>
In the LED socket of the present embodiment, the cantilever elastic support is provided in a point symmetrical position with respect to the center of the LED arrangement plane when the space in which the LED structure is arranged is viewed in plan from the LED light emitting surface side It is a thing.

<Configuration>
(Cantilever elastic support: point symmetrical position)
The LED socket of this embodiment is basically in common with any one of the LED sockets of the first to third embodiments. However, in the LED socket of this embodiment, the cantilever elastic supporting portion is provided at a point symmetrical position with respect to the center of the LED arrangement plane when the space in which the LED structure is arranged is viewed in plan from the LED light emitting surface side. It is characterized by the fact that it is The significance of this configuration is that by making the center of rotation when the base substrate thermally expands be substantially at the center of the LED structure, there is almost no change in the pressing force that the base substrate receives from the LED socket It is in the point which it did. As a result, even when the base substrate is thermally expanded, the possibility that the LED structure may be broken or malfunction may be largely eliminated.

  Furthermore, on the premise that the light emitting portion is disposed substantially at the center of the base substrate, the cantilever elastic support portion is disposed at a point symmetrical position with respect to the center of the LED arrangement plane in this manner. There is a significance that heat transfer accompanying heat radiation can be performed evenly. That is, with such an arrangement, the base substrate thermally expands with light emission, and even when the base substrate moves in the opposing inner side surface, the base substrate moves while maintaining the point-symmetrical arrangement in the opposing inner side surface. As described above, since the bearing receivers are disposed at point-symmetrical positions with respect to the base substrate moving in a point-symmetrical manner, it is possible to evenly transfer heat from the base substrate to the bearing receivers. The heat radiation effect can be improved.

  In the example shown in FIG. 14 described above, a pair of cantilevered elastic support portions 1402 a and 1402 b are provided at point-symmetrical positions with respect to the center 1415 of the LED arrangement plane.

  In the LED socket of this embodiment, both the bearing receiving portion and the cantilever elastic supporting portion are provided at point symmetrical positions with respect to the center of the LED arrangement plane when the LED structure is disposed. May be The example shown in FIG. 7 above is such an example. When configured in this manner, the above-described configuration with less risk of breakage due to thermal expansion of the base substrate can be realized more suitably.

(Feeding terminal: point symmetrical position)
Furthermore, when the power supply terminal is provided, when the LED structure is arranged, the power supply terminal is at the center of the LED arrangement plane when the space in which the LED structure is arranged is viewed in plan from the LED light emitting surface side. It may be configured to be provided as a pair at point symmetrical positions. The feed terminal is provided at the tip of a wire connected to an external power source, and is for contacting the feed pad of the LED structure to supply the LED with external power. The significance of this configuration is that the base substrate can be supported more firmly, as described above for arranging the bearing receiving portions in point-symmetrical positions. That is, by arranging the feeding terminals at point-symmetrical positions with respect to the center of the LED arrangement plane, when the base substrate is rotated, the feeding pads of the LED structures which are fixed in contact with the feeding terminals face each other. It is possible to rotate while maintaining point symmetry in the inner surface, and as a result, it is also possible to rotate the base substrate while maintaining point symmetry in the opposite inner surface. This causes the friction between the base substrate and the bearing support to be uniformly uniform and allows the base substrate to be properly supported by the bearing support.

<Effect>
According to the invention of the present embodiment, it is possible to further reduce the possibility of destruction or the like of the LED structure due to thermal expansion. In addition, the base substrate can be supported more appropriately, and the heat can be transferred uniformly with the heat released from the LED.

<Overview>
In the LED socket of this embodiment, at least a pair of bearing receiving portions and a pair of cantilever elastic supporting portions are disposed adjacent to each other.

<Configuration>
The LED socket of this embodiment is basically in common with the LED socket of the fourth embodiment. However, the LED socket of this embodiment is characterized in that at least a pair of bearing receiving portions and a pair of cantilever elastic supporting portions are disposed adjacent to each other. Here, “arranged adjacent to each other” means a state in which the area occupied by the bearing support and the area occupied by the cantilever elastic support are in contact or substantially in contact with each other. The example of FIG. 1 etc. mentioned above is such an example. The purpose of this configuration is to position the bearing support for supporting the LED structure in the front and back direction (vertical direction) and the cantilever elastic support responsible for horizontal support of the LED structure adjacent to each other. By arranging, it is to support the LED structure more firmly.

  FIG. 15 is a view for explaining an example of a state in which the bearing receiving portion and the cantilever elastic supporting portion are arranged adjacent to each other, and is a plan view of the LED socket. In the figure, the area occupied by the bearing receiving portion 1501a (the area surrounded by the broken line) is in contact with the area occupied by the cantilever elastic support 1502a (the area surrounded by the broken line) and the area occupied by the bearing receiving portion 1501b The region (generally enclosed by a broken line) is substantially in contact with the region occupied by the cantilever elastic support 1502a. The same applies to the relationship between the bearing receiving portions 1501c and 1501d, which make a pair with these, and the cantilever elastic supporting portion 1502b.

<Effect>
The invention of this embodiment makes it possible to support the LED structure more firmly. Moreover, it becomes possible to perform heat transfer accompanying heat dissipation from LED equally.

<Overview>
The LED socket of this embodiment is configured such that when the LED structure is disposed, the feed terminal is disposed in a position where it is pinched adjacent to the two bearing receivers.

<Configuration>
The LED socket of this embodiment is basically in common with any one of the LED sockets of the first to fifth embodiments. However, the LED socket of the present embodiment is characterized in that when the LED structure is disposed, the feed terminal is disposed at a position where it is pinched adjacent to the two bearing receiving portions. The meaning of "adjacent" is the same as the meaning in the previous embodiment. The purpose of this configuration is to support the LED structure in the front and back direction (vertical direction) as described above, since it is the bearing support that the feed terminals are supported by two bearing supports. By arranging the feed terminal in a position adjacent to the part, the feed terminal can be more firmly fixed, thereby avoiding the possibility of disconnection or the like due to the vibration of the feed terminal.

  FIG. 16 is a diagram for describing an example of a state in which the power supply terminal is disposed adjacent to the two bearing receiving portions when the LED structure is disposed, and the LED structure 1610 is disposed. The LED socket 1600 in the closed state is shown in a plan view. In this figure, the feed terminal (not shown in the figure but provided at a position to be in contact with the feed pad 1613) has two bearing support portions 1601a (area substantially surrounded by a broken line) and a bearing receiving portion 1601b (the same). It is a position which is sandwiched in the area occupied by the bearing of the bearing and is in a position substantially in contact with these areas (the same applies to the other feed terminal forming a pair).

<Effect>
According to the invention of this embodiment, it is possible to fix the feed terminal more firmly and to avoid the possibility of disconnection or the like.
