More specifically, the sealing member 43 which is an elastic member has an outer peripheral portion 437 of the sealing member 43 in a state where the translucent cover 30, the sealing member 43, and the end cover 40 are combined. It is attached to the end 36 while being sandwiched between the end 36 and the outer wall 410a. Further, the sealing member 43 which is an elastic member has an inner peripheral portion 435 of the sealing member 43 in an end portion in a state where the translucent cover 30, the sealing member 43, and the end cover 40 are combined. 36, and is attached to the end 36 in a state of being sandwiched between the end cover inner peripheral portion 425 which is an inner wall portion. That is, the sealing member 43, which is an elastic member, is brought into close contact with the end portion 36, the second cover main portion 420 as the inner end portion, the outer wall portion 410a, and the end cover inner peripheral portion 425 as the inner wall portion. The opening formed by the end portion 36 attached to the portion 36 is sealed.

  The end cover inner peripheral portion outer surface portion 4250 is an outer peripheral surface of the end cover inner peripheral portion 425, and forms an inclined surface as a first inclined portion. In the first direction (longitudinal direction X), the end cover inner peripheral portion outer surface portion 4250, which is the first inclined portion, moves from the second cover main portion 420 to the first cover main portion 410 in the first direction (longitudinal direction). X) is inclined so that the distance to the end 36 in the second direction intersecting with X) increases. That is, the distance from the end portion 36 in the second direction to the end portion 36 in the second direction increases as the distance from the center of the translucent cover 30 to the end portion 36 in the first direction increases. An end cover inner peripheral portion outer surface portion 4250 which is a first inclined portion that is inclined is formed. In other words, in the first direction (longitudinal direction X), the end cover inner peripheral portion outer surface portion 4250 moves from the first cover main portion 410 toward the second cover main portion 420 in the first direction (longitudinal direction). X) is inclined so that the distance from the end portion 36 in the second direction intersecting with X) becomes small. That is, the distance from the end 36 of the light-transmitting cover 30 toward the center in the first direction is reduced with respect to the end cover inner peripheral portion 425 that is the inner wall. An end cover inner peripheral portion outer surface portion 4250 which is a first inclined portion that is inclined is formed.

  The inclination angle θ2 of the inner peripheral portion outer surface portion 4250 with respect to the reference line T along the longitudinal direction X is such that the inclination angle θ2> 0 °, and preferably, the inclination angle θ2 ≧ the inclination angle θ1. In the case where the inclination angle θ2 is equal to the inclination angle θ1, the distance between the outer wall 410a and the inner peripheral portion 425 of the end cover in the second direction is equal to the length of the lamp 3. The same is true in the first direction, which is the direction X.

<Assembly of lamp 3>
When assembling the lamp 3, usually, first, the sealing tool 43 is attached to the end 36 of the translucent cover 30, and then the end cover 40 is attached to the translucent cover 30 with the sealing tool 43 interposed therebetween. The order of attachment to the end 36 is common. At this time, the translucent cover 30 is disposed between the inner peripheral portion outer surface portion 4352 and the outer peripheral portion inner surface portion 4370 of the sealing tool 43. For example, when assembling the lamp 3, the sealing member 43 fitted into the end cover 40 is difficult to come off, so that the lamp 3 can be assembled in a different order without impairing the assemblability. When assembling the lamp 3, the method and procedure for mounting (fitting) the sealing tool 43 have more options, so that the lamp 3 can be assembled by various procedures. In this embodiment, the outer peripheral portion 4250 of the inner peripheral portion of the end cover is formed over the entire periphery of the inner peripheral portion 425 of the end cover. Therefore, the second direction is all directions (360 °) crossing the first direction (longitudinal direction X). Note that the end cover inner peripheral portion outer surface portion 4250 that forms the inclined portion does not need to be provided on all surfaces of the outer peripheral surface of the end cover inner peripheral portion 425, and at least the end cover inner peripheral portion 425 What is necessary is just to be provided in a part of outer peripheral surface. Here, the part of the outer peripheral surface of the end cover inner peripheral part 425 may be either a part in the first direction (longitudinal direction X) or a part in the circumferential direction. The end cover inner peripheral portion outer surface portion 4250 may be provided at one location of the end cover inner peripheral portion 425, or may be provided at a plurality of locations.

<Effects>
As described above, the sealing member 43, which is an elastic member, includes the end portion 36, the first cover main portion 410, which is the outer end portion, the outer wall portion 410a, and the end cover inner peripheral portion 425, which is the inner wall portion. It is attached to the end 36 in a sandwiched state. The end cover inner peripheral portion 425, which is an inner wall portion, is configured such that the distance from the center of the light-transmitting cover 30 to the end portion 36 in the first direction increases as the distance from the end portion 36 in the second direction increases. An end cover inner peripheral portion outer surface portion 4250 which is a first inclined portion that is inclined is formed. The end cover inner peripheral portion 425 is provided with an end cover inner peripheral portion outer surface portion 4250, and the end cover inner peripheral portion outer surface portion 4250 is an elastic member fitted into the end cover 40 due to such inclination. Certain seals 43 are less likely to come off. The inner peripheral portion inner surface portion 4350 of the sealing member 43 faces the inclined end cover inner peripheral portion outer surface portion 4250 in a state where the first end cover 41, the second end cover 42, and the sealing member 43 are combined. Contact, and contact. When the first end cover 41, the second end cover 42, and the seal 43 are combined, the inner peripheral surface 4350 of the inner periphery of the end cover inner peripheral portion 425 of the end cover inner peripheral portion 425 of the seal 43 is formed. It makes surface contact with the outer surface 4250. Therefore, the movement of the inner peripheral portion 4350 of the inner peripheral portion of the sealing tool 43 is restricted by the inclination of the outer peripheral portion 4250 of the inner peripheral portion of the end cover. In the first direction (longitudinal direction X), a force is applied to the translucent cover 30 to which the sealing tool 43 is in close contact in a direction in which the sealing cover 43 comes out of the end cover 40 (a rightward middle direction X2 in FIG. 10). In this case, there is no possibility that the light-transmitting cover 30 and the sealing tool 43 come off from the end cover 40. If the sealing tool 43 moves in a direction in which the sealing tool 43 comes out of the end cover 40 (toward the right X2 in FIG. 10), the sealing tool 43 moves toward the end 36 of the translucent cover 30 (see FIG. 10). Move up). Therefore, the degree of adhesion between the light-transmitting cover 30 and the end cover 40 and the sealing member 43 is increased, and the light-transmitting cover 30 and the sealing member 43 are not easily detached from the end cover 40. More specifically, the lighting device 3 and the sealing structure 100 of the lighting device 3 include the end portion 36 of the translucent cover 30, the end cover inner peripheral outer surface 4250, and the end cover outer peripheral inner surface 4190 of the end cover 40. Thus, the degree of adhesion with the sealing tool 43 is increased. Therefore, in the lighting device 3 and the sealing structure 100 of the lighting device 3, the translucent cover 30 and the sealing device 43 do not easily come off the end cover 40. That is, in the lighting device 3 and the sealing structure 100 of the lighting device 3, there is no possibility that the translucent cover 30 and the sealing device 43 come off the end cover 40.

  The end cover 40 has the shape described above, and the amount of elastic deformation of the outer peripheral portion 437 of the sealing tool 43 is closer to rainwater inflow than the connecting section 436. Since the side of the main part 430 is relatively smaller, the lamp 3 can easily maintain the water stoppage. Moreover, the translucent cover 30 and the end cover 40 are strongly adhered to the sealing tool 43, and the lamp 3 is kept water-resistant. More specifically, the end portion 36 of the translucent cover 30, the end cover inner peripheral portion outer surface portion 4250 and the end cover outer peripheral portion inner surface portion 4190 of the end cover 40, and the sealing member 43 are strongly adhered to each other, The lamp 3 and the sealing structure 100 are kept water-tight.

  The translucent cover 30, which is an outer shell, is a long hollow body having at least one end 36 opened, and houses a substrate 62 on which the light emitting element 61 is mounted. The longitudinal direction X of 30 is the first direction. Therefore, the lamp 3 can secure the degree of adhesion between the translucent cover 30, the sealing member 43, and the end cover 40, and maintain the water stopping property. As a result, the lamp 3 and the sealing structure 100 of the lamp 3 Can protect the light emitting element 61 disposed inside the hollow body.

  The distance between the outer wall 410a in the second direction and the inner peripheral portion 425 of the end cover in the second direction is set such that the distance between the center of the translucent cover 30 which is the outer periphery in the first direction is equal to the distance from the center to the end. It becomes larger toward 36. Therefore, the sealing member 43, which is an elastic member fitted into the end cover 40, does not easily come off, because the inner surface 4250 of the end cover has an inclined outer surface. Further, the end portion 36 of the translucent cover 30, the outer peripheral portion 4250 of the end cover of the end cover 40, the inner peripheral portion 4190 of the outer peripheral portion of the end cover, and the sealing member 43 are strongly adhered to each other, and the lamp 3 and The sealing structure 100 of the lamp 3 maintains the water stoppage.

  Further, in the end cover 40, the distance between the outer wall portion 410a and the end cover inner peripheral portion 425, which is the inner wall portion, in the second direction may be the same in the first direction. In this case, the inclination of the end cover outer peripheral inner surface 4190 and the inclination of the end cover inner peripheral outer surface 4250 are at the same angle. It becomes easy to engage with the lid 40.

(Modification 1)
FIG. 11 is a schematic diagram illustrating a first modification of the sealing structure 100 of the lamp 3 according to the embodiment of the present invention. A draft taper is formed on the inner peripheral surface 4250a of the end cover so that the inclination angle θ3 required for normal resin molding is about 1 ° with respect to the reference line T along the longitudinal direction X. Have been. Further, this is a modification in which the inner surface 4190a of the outer peripheral portion of the end cover forms an inclined surface as a second inclined portion corresponding to the first inclined portion. In the first direction (longitudinal direction X), the end cover outer peripheral portion inner surface portion 4190a intersects with the first direction (longitudinal direction X) from the first cover main portion 410 toward the second cover main portion 420. It is inclined so that the distance from the end 36 is reduced in two directions. That is, the outer wall portion 410a is a second inclined portion that is inclined so that the distance from the end portion 36 of the translucent cover 30 toward the center in the first direction becomes smaller in the second direction. An end cover outer peripheral portion inner surface portion 4190a is formed. In other words, in the first direction (longitudinal direction X), the end cover outer peripheral portion inner surface portion 4190a that is the second inclined portion moves in the first direction from the second cover main portion 420 toward the first cover main portion 410 in the first direction. It is inclined so that the distance from the end 36 increases in the second direction intersecting. That is, the outer wall portion 410a is a second inclined portion that is inclined so that the distance from the center of the translucent cover 30 to the end portion 36 in the first direction increases with the distance to the end portion 36 in the second direction. An end cover outer peripheral portion inner surface portion 4190a is formed.

  The inclination angle θ4 of the inner surface 4190a of the outer peripheral portion of the end cover is such that the inclination angle θ4> 0 ° with respect to the reference line T along the longitudinal direction X, and preferably, the inclination angle θ4 ≧ the inclination angle θ3. When the inclination angle θ4 is equal to the inclination angle θ3, the distance between the outer wall 410a and the inner peripheral wall 425 of the end cover in the second direction is equal to the length of the lamp 3. The same is true in the first direction, which is the direction X. Further, a cover flange 426 is formed on the second end cover 42a, and in a state where the second end cover 42a and the sealing tool 43a are combined, the cover flange 426 is connected to the connecting portion 436 of the sealing tool 43a. Oppose, abut, and adhere to.

  As described above, the sealing member 43, which is an elastic member, includes the end portion 36, the first cover main portion 410, which is the outer end portion, the outer wall portion 410a, and the end cover inner peripheral portion 425, which is the inner wall portion. It is attached to the end 36 in a sandwiched state. The outer wall portion 410a has an end portion that is a second inclined portion that is inclined such that a distance from the center 36 of the light-transmitting cover 30 to the end portion 36 in the first direction increases with respect to the end portion 36 in the second direction.

Contact. Therefore, the movement of the outer peripheral portion 4372 of the outer peripheral portion of the sealing tool 43 is restricted by the inclination of the inner peripheral portion 4190a of the outer peripheral portion of the end cover. In the first direction (longitudinal direction X), a force is applied to the translucent cover 30 to which the sealing tool 43 is in close contact in a direction in which the sealing cover 43 comes out of the end cover 40 (a rightward middle direction X2 in FIG. 11). In this case, the translucent cover 30 and the sealing tool 43 do not have to be detached from the end cover 40. If the sealing tool 43 moves in a direction in which the sealing tool 43 comes out of the end cover 40 (the middle direction X2, which is to the right in FIG. 11), the sealing tool 43 moves toward the end 36 of the translucent cover 30 (see FIG. 11).

Since the side of the main part 430 is relatively smaller, the lamp 3 can easily maintain the water stoppage. Moreover, the translucent cover 30 and the end cover 40 are strongly adhered to the sealing tool 43, and the lamp 3 is kept water-resistant. More specifically, the end portion 36 of the translucent cover 30, the end cover inner peripheral portion outer surface portion 4250a and the end cover outer peripheral portion inner surface portion 4190a of the end cover 40, and the sealing member 43 are strongly adhered, The lamp 3 and the sealing structure 100 of the lamp 3 maintain water stoppage.

Then, the end cover 40, the sealing tool 43, and the translucent cover 30 are arranged. The reference installation environment condition is an environment condition based on a normal temperature (for example, 25 ° C.) as a reference temperature and a normal humidity (for example, a relative humidity of 40% to 50%) as a reference humidity, and is a general environment when assembling the lamp 3. It is also a condition. As shown in FIG. 15, the position P <b> 1 is the installation position of the first cover main part 410 of the end cover 40 in the longitudinal direction X of the lamp 3, and more specifically, the position P <b> 1 in the longitudinal direction X of the lamp 3. This is the installation position of the surface of the cover main portion 410 facing the fixing portion 46 of the connecting member 44. The position P2 is a setting position of the fixing portion 46 of the connecting member 44 in the longitudinal direction X of the lamp 3, and more specifically, the first cover main portion 410 of the fixing portion 46 in the longitudinal direction X of the lamp 3. This is the installation position of the surface facing the wall surface to be configured. That is, the end cover 40 is disposed in the movable range M in a state where the end cover 40 is separated from the fixing portion 46 of the connecting member 44. Further, since the sealing member 43 is sandwiched between the end cover 40 and the mounting member 50, the end cover 40 is not in direct contact with the mounting member 50 but is separated therefrom.

  The first movable range M1 is a space formed between the installation position of the first cover main portion 410 of the end cover 40 and the installation position of the fixing portion 46 of the connecting member 44 in the longitudinal direction X of the lamp 3. The distance between the installation position of the first cover main portion 410 and the installation position of the fixing portion 46. The first movable area M1 is an area for coping with the movement of the end 36 and the end cover 40 accompanying the extension of the translucent cover 30. The size of the first movable range M1 is determined, for example, in a range from the maximum extension dimension G of the translucent cover 30 to a half value (G / 2) of the maximum extension dimension G. When the elastic structure 110 is provided only at one end in the longitudinal direction X (first direction) of the lamp 3, it is preferable that the first movable range M <b> 1 be the maximum extension dimension G of the translucent cover 30. When the elastic structure 110 is provided at both ends in the longitudinal direction X (first direction) of the lamp 3, the first movable range M <b> 1 may be set to a half value (G / 2) of the maximum extension dimension G of the translucent cover 30.

  As shown in FIG. 15, the end cover 40 has a lamp so that the distance between the connecting member 44 and the mounting member 50 is larger than the distance between the mounting member 50 and the reference member under the standard installation environment conditions based on the reference temperature and the reference humidity. 3 in the movable range M. More specifically, in the standard installation environment conditions based on the reference temperature and the reference humidity, the end cover 40 has a larger distance between the fixing member 46 of the connecting member 44 than the distance between the fixing member 54 of the mounting member 50. Are arranged in the movable range M of the lamp 3 so as to be larger. At this time, the end cover 40 is arranged close to the mounting member 50 with the sealing tool 43 therebetween.

  The end cover 40 may be arranged in the movable range such that the distance between the end cover 40 and the attachment member 50 is larger than the distance between the connection member 44 and the reference member under the reference installation environment condition based on the reference temperature and the reference humidity. . More specifically, in the reference installation environment condition based on the reference temperature and the reference humidity, the end cover 40 has a smaller distance between the fixing member 54 of the mounting member 50 than the distance between the fixing member 46 of the connecting member 44. May be arranged in the movable range M of the lamp 3 so as to be larger. For example, this is an arrangement example of the end cover 40 on the assumption that the amount of shrinkage of the translucent cover 30 is large, such as when the use environment temperature of the lamp 3 is extremely low.

  The attachment member 50 has a fixture 54 that penetrates the end cover 40 and to which the connecting member 44 is fixed. The sealing member 43 that is an elastic member moves in a state in which the sealing member 43 is in close contact with the fixture 54.

Move outward (in the direction of X1) in the longitudinal direction X without change. When the end cover 40 and the end 36 of the light-transmitting cover 30 move, the sealing tool 43 comes into close contact with the end cover 40, the end 36 of the light-transmitting cover 30, and the boss 57, and the lamp 3. Is maintained (watertightness).

  As shown in FIG. 15, as the placement reference 2, under the reference installation environment condition, the end is set such that the translucent cover 30 has a range (second movable range M2) that can move to the position P4 with reference to the position P3. The lid 40, the sealing tool 43, and the translucent cover 30 are arranged. The position P3 is the position of the cover end 35 of the translucent cover 30, and the position P4 is the position of the fixture 54 of the mounting member 50. That is, the second movable range M2 is a distance between the cover end 35 and the fixture 54 in the longitudinal direction X of the lamp 3. The second movable range M2 is a region for coping with the movement of the end portion 36 and the end cover 40 due to the contraction of the translucent cover 30. The second movable range M2 is determined, for example, in a range from the maximum contraction dimension S of the translucent cover 30 to a half value (S / 2) of the maximum contraction dimension S. When the elastic structure 110 is provided only at one end in the longitudinal direction X (first direction) of the lamp 3, the second movable range M2 is preferably set to the maximum contraction dimension S. When the elastic structure 110 is provided at both ends in the longitudinal direction X (first direction) of the lamp 3, the second movable range M2 is sufficient to be a half value (S / 2) of the maximum contraction dimension S.

  As shown in FIG. 16, the end cover 40 can move to the position P2 in the first movable range M1 with reference to the position P1 shown in FIG. 15. The lid 40 can be moved from the position P1 to the position P2 by the movement distance. As shown in FIG. 16, when the light-transmitting cover 30 is extended to the maximum, that is, when the light-transmitting cover 30 is extended to the maximum within the range of the first movable range M <b> 1, the lighting device 3 is The maximum dimension in the direction X (first direction) is not exceeded. When the translucent cover 30 does not exceed the maximum dimension in the longitudinal direction X of the luminaire 2 in a state where the translucent cover 30 is maximally extended within the range of the first movable range M1, the luminaire 1 is brought close to the longitudinal direction. Even when the lighting devices 1 are installed, the lighting devices 3 of the lighting devices 1 do not collide with each other. A third movable range M3 shown in FIG. 16 is a range of movement of the end cover 40 and the sealing tool 43 to a position P6 based on the position P5. The position P5 is the position of the second cover main part 420 of the second end cover 42, and the position P6 is the position of the fixture 54 of the mounting member 50. That is, the third movable range M3 is a distance between the second cover main part 420 and the fixture 54 in the longitudinal direction X of the lamp 3. The third movable range M3 is a movable range when the translucent cover 30 contracts (returns) to the reference size from the state where the light-transmitting cover 30 is maximally extended, and is substantially the same as the first movable range M1.

  As shown in FIG. 15, a gap is formed between the head of the fixture 48 and the cylindrical wall of the connection guide 413 under the standard installation environment conditions. For this reason, as shown in FIG. 16, even if the end cover 40 moves in the longitudinal direction X with the extension of the end portion 36, the fixing tool 48 does not interfere with the cylindrical wall portion of the connection guide 413. . As a result, the fixing tool 48 does not hinder the movement of the end cover 40 on which the connection guide 413 is formed.

  FIG. 17 is an example of an arrangement of the end cover 40, the sealing tool 43, and the light-transmitting cover 30 in a state where the light-transmitting cover 30 is contracted within the range of the second movable range M2. As shown in FIG. 17, when the light-transmitting cover 30 contracts, for example, the end 36 of the light-transmitting cover 30 may move as shown in a position P7.

For this reason, even when the amount of extension of the translucent cover 30 is large due to a change in environmental conditions, for example, when the use environment temperature is extremely high, the area where the end 36 and the end cover 40 move is in the lamp 3. The movement of the end portion 36 and the end cover 40 is not hindered. Further, since the lamp 3 has the movable range M, it is possible to absorb a dimensional error due to a manufacturing variation of each part or an assembly variation of the lamp 3.

  In addition, the end cover 40 is disposed in the movable range M such that the interval dimension with the attachment member 50 is larger than the interval dimension with the connection member 44 under the standard installation environment condition based on the standard temperature and the standard humidity. ing. For this reason, even when the amount of shrinkage of the translucent cover 30 is large due to a change in environmental conditions, for example, when the use environment temperature is extremely low, the region where the end 36 and the end cover 40 move is in the lamp 3. As a result, the movement of the end 36 and the end cover 40 is not hindered.

  In addition, the end cover 40 is attached to the end portion 36 in a state in which the end cover 40 is in close contact with the sealing member 43 which is an elastic member disposed between the end portion 36 and the end portion 36. As a result, the lamp 3 can expand and contract while further maintaining the water stoppage.

  Further, the attachment member 50 has a fixture 54 that penetrates through the end cover 40 and to which the connecting member 44 is fixed, and the sealing member 43 that is an elastic member moves in a state of being in close contact with the fixture 54.
