Accordingly, the numerical values, shapes, materials, components, arrangement positions of components, and connection modes shown in the following embodiments are merely examples and are not intended to limit the present invention, and the present invention is not limited to the claims. Identified by Therefore, among the components in the following embodiments, components that are not described in the independent claim showing the highest concept of the present invention are not necessarily required to achieve the object of the present invention, It is described as constituting a preferred embodiment. Each figure is a schematic view and is not necessarily strictly illustrated.

Embodiment 1
First, the lamp according to the first embodiment of the present invention will be described including the background of the present embodiment.

With respect to the straight tube type LED lamp, the inventors of the present invention have also studied variously. For example, a straight tube type LED lamp as shown in FIG. 38 has been proposed. (A) of FIG. 38 is a cross-sectional view showing an example of a straight tube type LED lamp. (B) of FIG. 38 is a cross-sectional view of a straight tube type LED lamp cut along the line A-A 'of (a) of FIG.

The straight tube type LED lamp 1100 as shown in (a) and (b) of FIG. 38 includes a long LED module 1110 and a housing 1120 including a long glass tube for housing a plurality of LED modules. And a base 1150 made of an aluminum plate on which the LED module 1110 is mounted. The LED module 1110 includes an elongated substrate 1111 made of ceramics, a plurality of LEDs 1112 mounted on the substrate 1111, and a sealing member 1113 for collectively sealing the plurality of LEDs 1112.

In such a straight tube LED lamp 1100, the base 1150 is fixed to the inner surface of the housing 1120 by an adhesive 1160. Specifically, as shown in (a) and (b) of FIG. 38, the inner surface of the casing 1120 which is a cylindrical surface and the base 1150 which is a cylindrical surface having substantially the same shape as the inner surface of the casing 1120 The back surface is fixed by an adhesive 1160 made of a silicone resin applied to the entire back surface of the base 1150.

However, in the straight tube type LED lamp 1100 configured as described above, the entire long casing 1120 is warped, and there is a problem that distortion occurs in the lamp shape. For example, the whole of the case 1120 may be warped so that the central portion of the case 1120 is lifted, or both ends of the case 1120 may be bent upward, and the case 1120 may be bent. If distortion occurs in the housing 1120, there is a problem that the light orientation in the lamp is reduced, or the lamp can not be attached to the lighting apparatus.

The present invention has been made to solve such a problem, and has a first object to provide a lamp that suppresses the occurrence of distortion in the lamp housing.

In order to achieve the first object described above, one aspect of the first lamp according to the present invention is a long light source module including a long case and a semiconductor light emitting device housed in the case. And a mounting member for mounting the light source module to the housing, wherein the light source module is movable relative to the mounting member in the longitudinal direction of the housing.

Thereby, in the structure in which the light source module and the housing are attached, the influence of the difference in stress given to one of the light source module and the housing can be alleviated, and the stress difference between the light source module and the housing can be reduced It can be absorbed by the movement of the base. Therefore, it is possible to suppress the warpage of the housing and to suppress the occurrence of distortion in the housing.

Furthermore, in one aspect of the first lamp according to the present invention, a first cap provided at one end in the longitudinal direction of the housing, and another end provided in the longitudinal direction of the housing It is preferable that the light source module is attached to the first cap so that one end in the longitudinal direction of the light source module is a movable end with respect to the first cap.

Thus, the light source module can be held by the power supply base in a state in which one end of the light source module floats relative to the power supply base, so that the stress difference between the light source module and the housing can be determined by the movable end. Can also be absorbed.

Furthermore, in one aspect of the first lamp according to the present invention, the light source module includes an elongated first base, a second base disposed on the first base, and the second base And the movable end of the light source module is one end in the longitudinal direction of the second base, and The base may be movable relative to the mounting member in the longitudinal direction of the housing.

Furthermore, in one aspect of the first lamp according to the present invention, the first base has an opening, the mounting member has a hooking piece engaged with the opening, and the hooking piece is the first A first engaging portion formed with a gap from the edge of the opening in the longitudinal direction of one base, and a second engaging portion engaging with the edge of the opening It can be configured to slide relative to one base.

Furthermore, in one aspect of the first lamp according to the present invention, the mounting member may be fixed to the housing by an adhesive.

As mentioned above, according to one mode of the 1st lamp concerning the present invention, it can control that distortion occurs in a lamp case.

Further, as described above, in the straight tube type LED lamp 1100 as shown in (a) and (b) of FIG. 38, the base 1150 is a case with the adhesive 1160 made of silicone resin applied on the back surface. It is fixed to the inner surface of 1120. In addition, the LED module 1110 is fixed to the base 1150 by a fixing member such as a screw or an adhesive.

However, if a separate fixing member is used to fix the LED module 1110 and the base 1150, the number of parts increases and there is a problem that the manufacturing process becomes complicated. In particular, in consideration of the brittle fracture property of the ceramic substrate etc., in the straight tube type LED lamp 1100 as described above, the substrate 1111 constituting the LED module 1110 can not be extended to the entire length of the housing 1120, A plurality of substrates 1111, that is, a plurality of LED modules 1110 are disposed in 1120. As described above, since a plurality of LED modules are often used in the straight tube type LED lamp, if a separate fixing member is used as described above, the number of parts further increases and the manufacturing process becomes more complicated.

Furthermore, in the straight tube type LED lamp 100 as shown in (a) and (b) of FIG. 38, only the substrate 1111 and the base 1150 of the LED module 1110 are fixed together by screws or adhesives. In this case, the LED module 1110 may be detached from the base 1150 due to loosening of the screw or peeling of the adhesive. In particular, since the LED module 1110 is positioned on the ground side with respect to the base 1150 in the straight tube type LED lamp 1100 in a state of being attached to the lighting fixture, the LED module 1110 is connected to the base 1150 as described above. If the LED module 1110 falls off, the LED module 1110 may collide with the housing 1120 and may damage the housing 1120.

The present invention has been made to solve such a problem, and has a second object to provide a lamp capable of fixing a substrate of an LED module to a base with a simple configuration.

In order to achieve the second object, one aspect of the second lamp according to the present invention is a long case, a long first base housed in the case, and the long base. The first base includes a long substrate arranged on a first base, and a semiconductor light emitting element mounted on the substrate, the first base including a first wall portion and a second wall sandwiching both side surfaces of the substrate. A wall, a plurality of first protrusions projecting from the first wall toward the second wall, and a plurality of second protrusions projecting from the second wall toward the first wall The plurality of first protrusions and the plurality of second protrusions are in contact with a first surface of the substrate on which the semiconductor light emitting element is mounted.

Thus, the movement of the substrate in the direction perpendicular to the first surface of the substrate can be restricted by the first and second protrusions formed on the base, so that screws, adhesives, etc. are used. Thus, the substrate can be fixed to the first base.

Furthermore, in one aspect of the second lamp according to the present invention, the first base further has a biasing portion that biases toward a second surface which is a surface opposite to the first surface. Is preferred.

Thereby, since the second surface of the substrate can be biased by the biasing portion, the substrate is pressed by the first and second protrusions on the first surface side and the biasing portion on the second surface side. Receive Therefore, since the substrate is sandwiched from the surfaces on both sides of the first surface and the second surface, the substrate can be firmly held on the base.

Furthermore, in one aspect of the second lamp according to the present invention, it is preferable that the wall portion has a notch formed in the vicinity of at least one of the first protrusion and the second protrusion. .

As a result, since the first protrusion and the second protrusion can be easily elastically deformed, the substrate can be easily fixed to the first base.

Furthermore, in one aspect of the second lamp according to the present invention, the notch is formed in the vicinity of both the first protrusion and the second protrusion, and is formed in the vicinity of the first protrusion. It is preferable that the size of the notch differs between the notch and the notch formed in the vicinity of the second protrusion.

Thus, the projection provided in the vicinity of the notch where the size of the notch is larger can be easily elastically deformed.

Furthermore, in one aspect of the second lamp according to the present invention, the notch portion is formed at a position on a second surface side which is a surface opposite to the first surface with respect to the first surface of the substrate. Is preferred.

Thereby, since the notch can be positioned on the bottom side of the first base relative to the substrate, the voltage resistance near the notch edge of the notch can be improved, and from the notch Light leakage can be prevented to prevent deterioration of the lamp light distribution characteristics.

Furthermore, in one aspect of the second lamp according to the present invention, a second base is disposed between the first base and the substrate, and the substrate is placed on the second base. It may be configured as

As described above, according to one aspect of the second lamp of the present invention, the substrate on which the semiconductor light emitting element is mounted can be fixed to the base with a simple configuration.

As shown in FIGS. 7 (a) and 7 (b), in the present embodiment, the second base 154 has its end on the side of the base for power supply 130 in the longitudinal direction of the second base 154 be a base for power supply. It is attached to the power supply cap 130 so as to be a movable end with respect to 130. Specifically, a hole 154a is provided at an end of the second base 154 on the side of the power supply base 130, and the screw receiving portion 133 of the power supply base 130 inserted into the hole 154a is a hole 154a. It is configured to be able to move within.

In the present embodiment, the opening diameter (length) in the longitudinal direction (tube axis direction) of the second base 154 in the hole 154a is larger than the diameter (length) in the tube axis direction of the screw receiving portion 133. The opening diameter (length) of the second base 154 in the width direction of the hole 154 a is substantially equal to the diameter (length) of the second base 154 of the screw receiving portion 133 in the width direction. It is configured to be the same. Thereby, the second base 154 can be moved relative to the power supply cap 130. Then, since the second base 154 can slide relative to the attachment member 180 as described above, the power supply cap 130 and the ground can be moved as the light source module while being movable in the housing 120. It is held by the nozzle cap 140 and the housing 120.

Further, as shown in FIGS. 8A and 8B, in the present embodiment, the second base 154 has the end on the side of the base for grounding 140 in the longitudinal direction of the second base 154 grounded. It is attached to the grounding cap 140 so as to be a movable end with respect to the cap 140. Specifically, the end of the second base 154 on the side of the base for grounding 140 is fixed to the second base for grounding 141 b of the base for grounding 140 by a screw. Furthermore, a hole is provided at the end of the second base 154 on the side of the base for grounding 140, and the second base 154 is also inserted by inserting the screw receiving portion of the base for grounding 140 into the hole. Is fixed to the base for grounding 140.

Next, the operation and effect of the straight tube type LED lamp 100 according to the embodiment of the present invention will be described using FIG. FIG. 9 is a cross-sectional view for explaining the function and effect of the straight tube type LED lamp according to Embodiment 1 of the present invention.

In the straight tube type LED lamp 100 according to the present embodiment, as described above, the light source module is movable relative to the mounting member 180 in the longitudinal direction of the housing 120, and as shown by the arrow in FIG. The platform 150 is configured to slide relative to the mounting member 180 in the longitudinal direction of the housing 120. Thereby, since the light source module (or the first base 150) and the housing 120 are attached in a movable state without being fixed to each other, the configuration of the light source module (for example, the first base 150) and the housing Either one of the 120 can mitigate the effects of stress on the other.

That is, in the straight tube type LED lamp 1100 having the configuration shown in (a) and (b) of FIG. 38, since the base 1150 and the housing 1120 are different in material, the base 1150 and the housing 1120 The effect of the contraction action (compression stress) of the adhesive 1160 when the adhesive 1160 for fixing the adhesive hardens is different for the base 1150 and the housing 1120. In this case, since the base 1150 and the housing 1120 are fixed, a difference occurs in the stress due to the contraction action of the adhesive 1160, and the central portion of the housing 1120 floats up or both ends of the housing 1120 are upward. It is thought that it warps.

On the other hand, in the straight tube type LED lamp 100 according to the present embodiment, as described above, the light source module is movable relative to the mounting member 180 in the longitudinal direction of the housing 120 to configure the light source module ( For example, the influence of one of the first base 150) and the housing 120 on the other can be mitigated. That is, the stress difference due to the shrinking action of the adhesive when the adhesive cures can be absorbed by moving the first base 150. Thereby, since the warp of the housing 120 can be suppressed, generation of distortion in the housing 120 can be suppressed.

In addition, as in the present embodiment, in the elongated light source module (second base 154), one end in the longitudinal direction of the light source module is movable with respect to the power supply base 130. It is preferable to be attached to the power supply cap 130. Thus, the light source module (second base 154) can be held by the power supply nozzle 130 while one end of the light source module (second base 154) floats relative to the power supply nozzle 130. . Thus, by setting the end of the light source module as the movable end, the stress difference between the light source module and the housing 120 can be absorbed also by the movable end.

Next, a method of manufacturing the straight tube type LED lamp according to the first embodiment of the present invention will be described.

First, a method of assembling the light source module in the straight tube type LED lamp according to the present embodiment will be described with reference to FIG. FIG. 10 is a diagram showing an assembly process of the light source module in the straight tube type LED lamp according to Embodiment 1 of the present invention, wherein (a) is a diagram corresponding to a cross sectional view along line AA 'in FIG. 5 (b) is a view corresponding to a cross-sectional view taken along the line BB 'of FIG.

First, as shown in (a) and (b) of FIG. 10A, the mounting member 180 is attached to the first base 150. Then, as shown to (a) and (b) of FIG. 10 (B), the reflection member 170 is arrange | positioned inside the 1st base 150. FIG. Then, as shown to (a) and (b) of FIG.10 (C), the 2nd base 154 is arrange | positioned at the bottom of the reflection member 170. As shown in FIG. In FIGS. 10B and 10C, the reflecting member 170 and the second base 154 are disposed so as to bias the urging portion 153, but the reflecting member 170 and the second base are disposed. When disposing 154, the biasing portion 153 may not be biased.

Next, the LED module 110 is disposed on the first base 150. At this time, as shown in (a) and (b) of FIG. 10D, one of the width directions of the substrate 111 of the LED module 110 is The end is pressed against the second base 154 so that the one end is inserted between the first protrusion 151 a of the first base 150 and the main surface of the second base 154 in the figure. The one end of the substrate 111 is pushed in the direction indicated by the arrow. At this time, the substrate 111 is pushed so as to elastically deform the biasing portion 153.

Subsequently, as shown in (a) and (b) of FIG. 10 (E), the other end in the width direction of the substrate 111 is pushed in the direction shown by the arrow in the drawing to Is inserted between the second protrusion 152 a and the second base 154. At this time, since the biasing portion 153 is provided on the first base 150, the other end is inserted between the second projecting portion 152a and the second base 154, and at the same time, the biasing portion 153 The substrate 111 is brought into contact with the second protrusion 152 a by pressing from below.

Thus, as shown in (a) and (b) of FIG. 10 (F), both ends of the substrate 111 of the LED module 110 are divided into a first protrusion 151a, a second protrusion 152a, and a second base 154. Can be sandwiched between

Further, in the present embodiment, since the first notch 151b and the second notch 152b are provided around the first protrusion 151a and the second protrusion 152a, the first protrusion 151a and the second notch 152b are provided. The protrusion 152a can be easily elastically deformed. Thus, both ends of the substrate 111 can be easily inserted between the first protrusion 151 a or the second protrusion 152 a and the second base 154.

After this, the lighting circuit 190 is disposed on the second base 154, and electrical connection between the LED modules 110 and the LED module 110 and the lighting circuit 190 is made by the connector 160. Make an electrical connection with Thereafter, the lighting circuit cover 191 is attached to the first base 150 so as to cover the lighting circuit 190. Thus, the light source module can be assembled.

Thereafter, the light source module is inserted into the housing 120, and then the power supply base 130 and the grounding base 140 are attached to the both ends of the housing 120.

As mentioned above, although the lamp concerning this embodiment was explained, the present invention is not limited to the above-mentioned embodiment.

For example, in the above embodiment, the lighting circuit cover that covers the lighting circuit 190 may be the lighting circuit cover 192 configured as shown in FIG. 11A. FIG. 11A is a diagram showing a configuration of a lighting circuit cover in a straight tube type LED lamp according to Variation 1 of Embodiment 1 of the present invention. As shown in FIG. 11A, in the present modification, the first convex portion 192a and the second convex portion 192b are provided on both side surfaces of the lighting circuit cover 192, and the first convex portion 192a and the first convex portion 192a are formed on the first base 150. The 1st hole 151c and the 2nd hole 152c which fit with the 2nd convex part 192b are provided. Thus, the first base 150 and the lighting circuit cover 192 can be easily fixed.

Further, in the above embodiment, although the amount of protrusion of the first protrusion 151a and the amount of protrusion of the second protrusion 152a are the same, it is assumed that the amount of protrusion of the first protrusion 151a and the amount of protrusion of the second protrusion 152a are different. You may configure it. In this case, when the LED module 110 is fixed to the first base 150, the protrusion amount of the protrusion corresponding to the end of one of the both ends in the width direction of the substrate 111 which is pushed into the protrusion later. It is preferable to reduce the size. For example, in FIG. 6, the protrusion amount of the second protrusion 152a is preferably smaller than the protrusion amount of the first protrusion 151a. As a result, while holding power to the substrate 111 is maintained by the first protrusion 151a having a large protrusion amount, the substrate 111 can be easily fixed to the first base 150 by the second protrusion 152a having a small protrusion amount. Can be

Moreover, in the above embodiment, in the first base 150, notches are formed in both the first wall 151 and the second wall 152, and the first notch 151b and the second notch 152b are formed. Although provided, it is not limited to this. For example, the notch may be formed in only one of the first wall 151 and the second wall 152.

Further, in the present embodiment, the size (slit width and slit length) of the opening (slit) in the first notch 151 b and the size of the opening in the second notch 152 b are the same, but the present invention is limited thereto Absent. For example, the size of the opening in the first notch 151b may be different from the size of the opening in the second notch 152b. In this case, when the LED module 110 is fixed to the first base 150, the LED module 110 is formed in the vicinity of the protrusion corresponding to the end of one of the widthwise ends of the substrate 111 which is pushed into the protrusion later. It is preferable to increase the size of the opening in the direction of the notch. For example, in FIG. 6, the size of the opening in the second notch 152b is preferably larger than the size of the opening in the first notch 151b. As a result, the portion near the second protrusion 152a is more easily elastically deformed than the portion near the first protrusion 151a, so that the substrate 111 can be more easily fixed to the first base 150. it can. The size of the opening of the notch can be changed, for example, by adjusting the slit width or the slit length.

Further, in the present embodiment, although the first notch 151b and the second notch 152b are slit-shaped opening holes, the present invention is not limited to this. For example, the first notch 151 b and the second notch 152 b may be formed by notching the first wall 151 and the second wall 152 so as not to penetrate the first wall 151 and the second wall 152. Even with this configuration, the elastic force of the first protrusion 151a and the second protrusion 152a can be increased.

Further, in the present embodiment, when the substrate 111 is fixed to the first base 150, as shown in FIG. 6, one end of the substrate 111 in the width direction on the side of the first protrusion 151a is a first protrusion After being inserted between 151 a and the second base 154, the other end in the width direction of the substrate 111 on the second protrusion 152 a side is inserted between the second protrusion 152 a and the second base 154. However, the order may be reversed. Alternatively, both ends in the width direction of the substrate 111 may be simultaneously inserted between the first protrusion 151 a and the second protrusion 152 a and the second base 154.

Further, in the above embodiment, although the power supply cap 130 is a movable end and the grounding cap 140 is a fixed end, the present invention is not limited to this. For example, the feed cap 130 may be a fixed end, and the grounding cap 140 may be a movable end, or both the feeding cap 130 and the grounding cap 140 may be movable ends. I don't care. Accordingly, the light source module can be held by the power supply base 130, the ground base 140, and the housing 120 while the light source module is movable in the housing 120. Note that both the power supply cap 130 and the ground cap 140 can be fixed ends. In this case, although the light source module can not be made movable in the housing 120, the light source module can be firmly held in the housing 120.

In the above embodiment, although the single-sided feeding method in which power feeding is performed from one side of only the feeding cap 130 is described, it may be a double-sided feeding method in which power is supplied from both sides. Further, even in the case of the one-sided power feeding method as in the present embodiment, the base portion may be configured without using the base for the grounding 140 as the non-power-supply-side base. In this case, in place of the grounding cap 140, a mounting cap having a structure to be attached to a socket of a lighting fixture may be provided at the location of the grounding cap 140. For example, the grounding cap 140 in the present embodiment may be used as it is, and the grounding pin 142 may not be grounded.

Moreover, in said embodiment, although the LED module 110 was set as the structure of the COB type which mounted the LED chip directly on the board | substrate 111, it does not restrict to this. For example, an LED chip is mounted in a resin-molded cavity, and the inside of the cavity is sealed with a phosphor-containing resin, that is, a surface mount type (SMD) LED is used, and this SMD type LED is long A plurality of LED modules may be configured by mounting a plurality of the substrates on the substrate.

In the above embodiment, the first base 150 can also be the first base 150A configured as shown in FIG. 11B. FIG. 11B is a view showing the configuration of the first base in the straight-tube type LED lamp according to Variation 2 of Embodiment 1 of the present invention, wherein (a) is a plan view of the first base, b) is a cross-sectional view taken along the line AA 'of (a), and (c) is a cross-sectional view taken along the line BB' of (a). As shown in FIG. 11B, in the first base 150A according to the present modification, the surface of the bottom of the first base 150A on the housing 120 side has a convex portion 155 formed by punching, pressing, or the like. . The convex portion 155 is a protruding portion provided on the surface of the bottom portion of the first base 150A on the side of the housing 120 and functions as a pedestal to which an adhesive such as a silicone resin is applied. That is, after the first base 150A is disposed on a predetermined inner surface of the housing 120 in a state where the adhesive 183A is applied to the convex portion 155 in advance, the first base 150A and the housing 120 are pressed and fixed. . Then, the first base 150A is fixed to the inner wall of the housing 120 via the adhesive 183A. At this time, the first base 150A and the housing 120 are fixed only via the convex portion 155 provided on a part of the bottom of the first base 150A. Conventionally, when a first base or the like provided with an LED is fixed to a tube-shaped casing, the first base is previously connected via a series of adhesives disposed along the longitudinal direction of the first base. The method of fixing a stand and a housing was common. However, in this conventional method, since the first base is fixed to the casing in series along the longitudinal direction, for example, when the straight tube type LED lamp is repeatedly turned on / off, the first base is repeated. Due to the difference in thermal expansion coefficient between the base and the housing, the bonding strength at the time of fixing is reduced, and there may be a problem such as the first base and the housing being detached. On the other hand, in the present modification, as described above, the convex portion 155 is partially provided at the bottom of the first base 150A, and the first base 150A and the housing are formed via the convex portion 155 with the adhesive. By fixing 120, the adhesion strength between the first base 150A and the housing 120 is kept high without being affected by the difference in thermal expansion coefficient at the time of lighting / lighting out. As a result, the high quality of the straight tube type LED lamp is maintained without the occurrence of problems such as detachment of the members. In addition, the convex part 155 can also be replaced with the attachment member 180 in the said embodiment, and can be provided. In addition, the convex portion 155 provided on the bottom of the first base 150A can reduce the difference in thermal expansion coefficient between the first base 150A and the housing 120 while maintaining good adhesion strength. It is preferable that a plurality be provided at intervals along the longitudinal direction of the base 150A. For example, five pieces may be provided at equal intervals along the longitudinal direction of the first base 150A, or two pieces may be provided in place of the attachment members 180 in the above embodiment. In addition, along the longitudinal direction does not mean only one line, but two or more lines may be provided in parallel to provide the convex portion 155.

Second Embodiment
Next, the lamp according to the second embodiment of the present invention will be described including the background of the present embodiment.

In the conventional straight tube type LED lamp, there is a problem that the half structure of the half structure can not be formed with high accuracy.

That is, in the mouthpiece into which the end of the housing is inserted, screwing can not be performed at the position where the housing is inserted, so the screwing position is closer to the tip of the mouthpiece. For this reason, since two members which comprise the main part of a nozzle | cap | die can not be screwed with sufficient balance, the said nozzle | cap | die can not be formed precisely. As a result, the base can not be fixed to the housing with high accuracy, or a gap is formed between the two members constituting the base of the base, causing problems such as leakage of light from the LED and entry of dust from the gap. .

The present invention has been made to solve such a problem, and has a third object to provide a lamp capable of precisely forming a half-split nozzle.

In order to achieve the above third object, one aspect of the third lamp according to the present invention is a lamp attached to the lighting fixture via a socket provided in the lighting fixture, and the semiconductor light emission is performed inward And a connecting portion provided at an end of the housing in the longitudinal direction and having a distal end detachably connected to the socket, wherein the connecting portions are mutually connected. It has a first main body portion and a second main body portion that constitute the main body of the connection portion by fitting, and the first main body portion has a plurality of protrusions having different distances in the longitudinal direction from the end portion of the housing. The second main body portion has a plurality of fitting portions which are fitted with the plurality of protrusions at positions corresponding to the plurality of protrusions, respectively.

According to this, the lamp is provided with the connection part which is a base, and the connection part is provided with the first main body and the second main body which constitute the main body by fitting, and the first main body is A plurality of protrusions having different longitudinal distances from the end of the elongated case, and the second main body having a plurality of fitting portions to be fitted with each of the plurality of protrusions. That is, the lamp is inserted because the main body including the first main body and the second main body is configured by fitting the plurality of projections and the plurality of fitting portions instead of screwing. The first main body and the second main body can be fixed in a well-balanced manner regardless of the position of the housing. Thereby, the nozzle | cap | die of a half structure can be formed precisely.

Further, in one aspect of the third lamp according to the present invention, the first main body portion is a gap with the second main body portion when the plurality of projecting portions and the plurality of fitting portions are fitted. The first main body overlapping the second main body so as to close the first main body, and the second main body having the first main body in the case where the plurality of protrusions and the plurality of fitting portions are fitted to each other It is preferable to have a second overlap portion overlapping with the first overlap portion so as to close a gap with the main body portion.

According to this, the first main body portion and the second main body portion have the first overlapping portion and the second overlapping portion so that the gap is eliminated when the plurality of protrusions and the plurality of fitting portions are fitted. Overlap. That is, since the first main body and the second main body overlap and fit, it is possible to prevent a gap from being formed between the first main body and the second main body. Thereby, it is possible to prevent the light of the LED from leaking between the first main body and the second main body and preventing dust, insects and the like from entering.

In one aspect of the third lamp according to the present invention, preferably, the plurality of protrusions are fitted to the plurality of fitting portions from the inside of the second main body.

According to this, the plurality of protrusions are fitted to the plurality of fitting portions from the inside of the second main body portion. Therefore, the first main body portion and the second main body portion can not be easily separated, and an electric shock or the like due to the unintentional separation of the first main body portion and the second main body portion can be prevented.

Moreover, in one aspect of the third lamp according to the present invention, the connection portion further includes the first main body portion and the second main body portion between an end portion of the housing and a tip end portion of the connection portion. It is preferable to provide a fixing member for fixing the part.

According to this, the first main body and the second main body are further fixed by the fixing member between the end of the housing and the tip of the connection. For this reason, since the first main body and the second main body are further fixed by screwing or the like, the fitting between the first main body and the second main body is strengthened, and the base of the half-split structure is accurate It can be formed.

In one aspect of the third lamp according to the present invention, the end of the housing has a smaller diameter as it gets closer to the tip, and the plurality of protrusions are the first main body and the second main body. It is preferable that the main body portion be fitted to the plurality of fitting portions so as to surround an end portion of the housing.

According to this, the diameter of the end of the casing becomes smaller toward the tip, and the plurality of protrusions are arranged such that the first main body and the second main body surround the end of the casing. And the plurality of fitting portions are fitted. Here, when the end of the housing is sandwiched between the first main body and the second main body, a force is applied from the outside to the inside of the end, and the end of the housing may be broken. However, if the diameter of the housing becomes smaller as it approaches the tip end in this way, cracking of the end of the housing can be prevented. The diameter of the end portion of the casing is processed so as to be smaller as it approaches the tip portion by performing a process (glazing) of heating the end portion of the glass tube which is the casing. For this reason, even if the case is sandwiched between the first main body portion and the second main body portion, it is possible to prevent the end of the case from being broken and to form the base of the half structure with high accuracy.

As mentioned above, according to one mode of the 3rd lamp concerning the present invention, a nozzle of a half structure can be formed with sufficient accuracy.

Hereinafter, a straight tube type LED lamp according to Embodiment 2 of the present invention will be described with reference to the drawings. Also in the present embodiment, a straight tube type LED lamp replacing the conventional straight tube fluorescent lamp will be described in detail as an example.

FIG. 12 is a perspective view showing an appearance of a straight tube type LED lamp 200 according to Embodiment 2 of the present invention.

As shown in the figure, the straight tube type LED lamp 200 is a straight tube type LED lamp having substantially the same shape as a conventional general straight tube fluorescent lamp using an electrode coil, and has a long cylindrical casing 230; The LED module 231 and the base 232 disposed inside the housing 230, and the first connection portion (grounding cap) 210 and the second connection portion (power feeding cap) 220 connected to both ends of the housing 230 And have.

The housing 230 is a long straight pipe (envelope) for housing the LED module 231 and the base 232. That is, the housing 230 is an elongated cylindrical body having openings at both ends, and the cross-sectional shape thereof is annular. The housing 230 can be made of a translucent material such as a glass tube or a plastic tube. The casing 230 is not limited to a casing having an annular cross section, and the outer periphery of the cross section has an angular or semicircular shape, and the inner periphery has a circular or semicircular shape. It may have any shape, such as an angular shape.

When the lamp 200 can be used in an environment where it is exposed to high temperatures and high temperatures such as emergency lights, the housing 230 is preferably formed of a glass tube. The use of a glass casing 230, which is an inorganic material, is extremely excellent in heat resistance as compared to a plastic tube or the like. This is because the risk of breakage and deformation of the body 230 is extremely low.

Further, for example, when the shape of the inner peripheral edge of the case 230 according to the present embodiment is semicircular (referred to as a first case), a second case formed of an aluminum plate or the like is prepared. The housing 230 may be configured by combining the first and second housings. In this case, the second housing can also use a member acting as a base 232 described later.

The LED module 231 includes an LED and a mounting substrate. The LEDs are an example of a semiconductor light emitting element, and are mounted directly on the mounting substrate, and are arranged in a line (in a straight line) in a row along the longitudinal direction of the mounting substrate. The mounting substrate is an LED mounting substrate for mounting an LED, and in the present embodiment, is a long rectangular substrate. As the mounting substrate, a ceramic substrate made of alumina or translucent aluminum nitride, an aluminum substrate made of an aluminum alloy, a transparent glass substrate, a flexible flexible substrate (FPC) made of a resin, or the like can be used.

As described above, the LED module 231 according to the present embodiment has a structure in which the plurality of LEDs mounted on the mounting substrate are collectively sealed by the sealing body. The sealing body is mainly made of a translucent material, but if it is necessary to convert the wavelength of the light emitted from the LED to a predetermined wavelength, the wavelength to convert the wavelength of the light to the translucent material Conversion materials are incorporated.

For example, a silicone resin can be used as the translucent material, and phosphor particles can be used as the wavelength conversion material, for example.

In the present embodiment, an LED emitting blue light and a sealing body formed of a translucent material mixed with phosphor particles for wavelength-converting blue light into yellow light are adopted. A part of the emitted blue light is wavelength-converted to yellow light by the sealing body, and white light generated by mixing the unconverted blue light and the converted yellow light is emitted from the LED module 231.

The restricting portion is an abutting portion that abuts on the main body portion, and an abutment in which a distance in a direction perpendicular to the central axis from the central axis of the shaft of the supporting portion is equal to or larger than the radius of the axial body Have a department. That is, in the plane orthogonal to the central axis of the shaft, the restricting portion has a portion having a size equal to or larger than the radius of the shaft in the radial direction of the shaft. As a result, the radius of rotation of the restricting portion about the central axis becomes larger than the radius of rotation of the support portion about the central axis, so that the strength against rotational torque generated in the support portion can be improved. For this reason, even when rotational torque is generated in the support portion that supports the base with respect to the socket, damage to the base can be suppressed.

It may have any shape, such as an angular shape.

Also, for example, when the shape of the inner peripheral edge of the case 330 according to the present embodiment is semicircular (referred to as a first case), a second case formed of an aluminum plate or the like is prepared. The first and second housings may be combined to form the housing 330. In this case, the second housing can also use a member acting as a base 332 described later.

As mentioned above, according to the straight tube | pipe type LED lamp 300 which concerns on Embodiment 3 of this invention, the main body part 311 of the 1st connection part 310 which is a nozzle | cap | die, and the 1st socket of a lighting fixture are connected and straight tube form The LED lamp 300 includes a support 313 that supports the LED lamp 300 with respect to the lighting fixture, and a restricting unit 314 that is fixed to the support 313 and that restricts the rotation of the support 313 with respect to the main body 311. The restricting portion 314 is the

contact portions

314c and 314d in contact with the main body portion 311, and the distance in a direction perpendicular to the central axis 313d from the central axis 313d of the shaft 313b of the support portion 313 is It has

abutment parts

314c and 314d which are equal to or larger than the radius. That is, the restricting portion 314 has a portion having a size equal to or larger than the radius of the shaft 313 b in the radial direction of the shaft 313 b in a plane orthogonal to the central axis 313 d of the shaft 313 b.

The rotation torque resistance generated in the support portion 313 is preferably 1 to 2 Nm or more, but according to the above configuration, the rotation radius of the restriction portion 314 around the center axis 313 d is the same as that of the support portion 313 around the center axis 313 d. As it becomes larger than the rotation radius, the strength against the rotational torque generated in the support portion 313 can be improved. For this reason, even when rotation torque generate | occur | produces to the support part 313 which has supported the nozzle | cap | die with respect to a 1st socket (lighting fixture), damage to a nozzle | cap | die can be suppressed.

In addition, the

contact portions

314 c and 314 d contact the main body portion 311 of the first connection portion 310 at at least two points at which the distances from the central axis 313 d of the shaft 313 b of the support portion 313 are different. That is, the restricting portion 314 is not circular with the axis of the support portion 313 as the center. For this reason, when rotational torque is generated in the support portion 313, the strength with respect to the rotational torque generated in the support portion 313 can be improved without the control portion 314 idling.

Further, the

contact portions

314 c and 314 d are planar regions formed in the restricting portion 314. That is, when the restricting portion 314 abuts on the main portion 311 of the first connection portion 310 in a plane, the strength against the rotational torque generated in the support portion 313 can be improved. Thereby, even when rotation torque generate | occur | produces in the support part 313 which has supported the nozzle | cap | die with respect to a 1st socket (lighting fixture), damage to a nozzle | cap | die can be suppressed.

In addition, the support portion 313 is an earth pin. That is, the first connection portion 310 is a base for grounding provided with a grounding pin. Here, when the ground pin is rod-like and the ground cap is provided with only one ground pin, the ground cap has weak strength against rotational torque to the ground pin. For this reason, by using the restricting portion 314, it is possible to improve the strength with respect to the rotational torque with respect to the grounding cap. As a result, even when a rotational torque is generated in the support portion 313 supporting the grounding cap with respect to the first socket, damage to the grounding cap can be suppressed.

Further, the base 332 is electrically connected to the support portion 313 via the restricting portion 314 by being connected to the restricting portion 314. That is, the base 332 is electrically connected to the ground pin via the restricting portion 314.
