The outer periphery of the coupling packing 8 has a lamp tube insertion portion 8a at both ends, a lamp holder receiving portion 8b at the center, and a lamp tube end positioning rib 8c between the lamp tube insertion portion 8a and the lamp holder receiving portion 8b.
On the inner periphery of the coupling packing 8, eight triangular inner ribs 8d are arranged in the longitudinal direction.

FIG. 4 is a cross-sectional view of an end portion of the lamp tube unit in the present embodiment.
The straight tube lamp 3 includes a base part 3b provided at both ends of the glass part 3a, a base pin 3c attached to the base part 3b, and a filament 3d electrically connected to the base pin 3c.

  The lamp tube 7 is fixed by the lamp tube insertion portion 9a of the end packing 9 and the positioning rib 9b. The lamp tube insertion portion 9a is about 15 mm, and by chamfering the tip, a stable mounting state can be obtained while securing the light emitting surface of the straight tube lamp 3, and the workability of mounting and removing is good.

  The lamp tube 7 is made of, for example, polycarbonate and does not transmit the ultraviolet rays preferred by insects, which are emitted from the straight tube lamp 3, and has an effect of preventing insects from coming close.

FIG. 5 is a cross-sectional view of the central portion of the lamp tube unit in the present embodiment.
The end of the lamp tube 7 is attached and fixed by the lamp tube end positioning rib 8c on the outer surface of the coupling packing 8.

  When the length of the lamp tube insertion portion 8a of the coupling packing 8 is about 15 mm, a stable mounting state can be obtained while securing the light emitting surface of the straight tube lamp 3 (the amount of light shielded by the coupling packing 8 is small) Moreover, the workability of attachment and removal is good.

  Moreover, the workability | operativity which attaches the lamp tube 7 improves by chamfering the front-end | tip part of the lamp tube insertion part 8a.

  The procedure for attaching the lamp tube 7 to the straight tube lamp 3 is, for example, as follows.

  First, the coupling packing 8 is attached to the center of the straight tube lamp 3 in the longitudinal direction.

  Next, the end packing 6 is attached to one end of the lamp tube 7.

  Next, the straight tube lamp 3 with the coupling packing 8 attached is inserted from the side of the lamp tube 7 where the end packing 9 is not attached.

  Next, the end of the lamp tube 7 is attached with the coupling packing 8.

  Similarly, the straight tube lamp 3 having the lamp tube 7 already attached to one side is inserted from the side of the lamp tube 7 to which the end packing 9 is attached, where the end packing 9 is not attached.

  Finally, the two lamp tubes 7 are attached with the coupling packing 8.

The procedure for attaching the straight tube lamp 3 to which the lamp tube 7 is attached to the luminaire 1 is, for example, as follows.
First, the straight tube lamp 3 is attached to the socket 4 of the lighting fixture 1.

  Finally, the lamp holder 6 of the lighting fixture 1 is attached to the lamp holder receiving portion 8 b of the coupling packing 8.

  A lamp holder receiving portion 8 b for attaching the lamp holder 6 is provided on the outer surface of the coupling packing 8. The lamp tube end positioning rib 8c functions as positioning when the lamp holder 6 is mounted. When the lamp holder 6 is attached to the lamp tube end positioning rib 8c, the coupling packing 8 and the straight tube lamp 3 are mounted. Is fixed stably.

  The material of the coupling packing 8 is optimally about 50 hardness of silicon rubber in consideration of the mounting property and the vibration countermeasure when using the luminaire 1. When the vibration of the luminaire 1 is transmitted from the lamp holder 6, the vibration can be absorbed by the inner rib 8 d and the straight tube lamp 3 can be moderated.

  By using elastic silicone rubber for the coupling packing 8, frictional resistance is generated at the tips of the inner ribs 8 d at a plurality of locations and the outer diameter of the straight tube lamp 3, and reliable fixing can be achieved.

FIG. 6 is a cross-sectional view showing the lighting fixture in the first embodiment.
The coupling packing 8 includes eight inner ribs 8d on the inner side and in the longitudinal direction of the coupling packing 8.

  The inner rib 8d fixes the straight tube lamp 3 by a force applied to the lamp holder receiving portion 8b of the connecting packing 8 when the connecting packing 8 is fixed to the lamp holder 6.

  The inner rib 8d disposed in the longitudinal direction of the coupling packing 8 reduces the frictional resistance in the insertion direction when the straight tube lamp 3 is attached, and facilitates the insertion of the straight tube lamp 3.

  After the straight tube lamp 3 with the lamp tube unit 5 attached is attached to the socket 4 and the lamp holder 6, the straight tube lamp 3 is stabilized by the contact with the outer diameter of the straight tube lamp 3 of the plurality of inner ribs 8d. And fix.

  The shape of the inner rib 8d of the coupling packing 8 is preferably a triangular shape in consideration of the mounting property of the straight tube lamp 3, but may be a trapezoidal shape, a quadrangular shape or a semicircular arc shape. Also good.

  The plurality of inner ribs 8d of the coupling packing 8 are arranged at eight positions at equal intervals in the longitudinal direction of the straight tube lamp 3, and spaces between the inner ribs 8d can be formed to ensure air fluidity. it can.

  Therefore, the ambient temperature of the straight tube lamp 3 covered by the two lamp tubes 7 can be kept substantially constant, and a stable light flux of the straight tube lamp 3 can be obtained.

  Thus, since the inner rib 8d is provided inside the coupling packing 8, the straight tube lamp 3 can be stably fixed and the fluidity of the air can be obtained.

  When the lighting fixture 1 is composed of two lamp tubes 7, the lamp holder 6 is positioned at the center of the lighting fixture 1. Since the coupling packing 8 receives the lamp holder 6 at the lamp holder receiving portion 8b, the two lamp tubes 7 can be configured with the same length.

  Since the lamp tube 7 having the same length can be used, the productivity of the lamp tube 7 can be improved and erroneous packaging can be avoided.

  Since they have the same length, when they are constituted by a plurality of lamp tubes 7, there is no designation of the attachment location, and assembly is easy.

  In the present embodiment, two lamp tubes 7 are attached to the luminaire 1. However, a configuration in which more than two lamp tubes 7 are attached by a plurality of coupling packings 8. Can be taken.

  Moreover, the structure which fixes the some packing 8 for connection with the some lamp holder 6 can be taken. In this case, a stable fixed state can be obtained by adjusting the length of the lamp tube 7 in accordance with the arrangement interval of the lamp holder 6 to the luminaire 1.

A case where the number of the inner ribs 8d in the present embodiment is changed will be described.
The number of the inner ribs 8d will be described using FIG. 7 while comparing with the coupling packing 8 shown in FIG.

  FIG. 7 shows a modification of the number of inner ribs 8d for attaching the straight tube lamp 3 of the coupling packing 2 shown in FIG. 6, and FIG. 7 (a) shows that when the number of inner ribs 8d is three, FIG. 7B shows a case where the number of inner ribs 8d is 16.

  7 (a) and 7 (b) has the same function as the coupling packing 8 shown in FIG.

  As shown in FIG. 7A, it is possible to fix the straight tube lamp 3 with at least three inner ribs 8d. The connecting packing 8 shown in FIG. 6 has three inner ribs 8d, whereas the straight tube lamp 3 is inserted into the lamp tube 7 and the connecting packing 8 when the inner rib 8d is eight. 3 and the inner rib 8d have a small amount of contact, so the frictional resistance is small and the straight tube lamp 3 can be easily inserted.

  However, when the lamp holder 6 is attached to the outer diameter of the coupling packing 8, the interval between the inner ribs 8d is wide, and the stability of the attachment state of the straight tube lamp 3 is inferior.

  As shown in FIG. 7B, by increasing the inner rib 8d, the straight tube lamp 3 and the lamp holder 6 can be stably attached as compared with the coupling packing 8 shown in FIG.

  However, the coupling packing 8 shown in FIG. 6 has 16 inner ribs 8d, whereas the inner ribs 8d have 16 spaces, and the air fluidity is reduced.

  Further, since the amount of contact between the straight tube lamp 3 and the inner rib 8d increases, when the straight tube lamp 3 is inserted into the lamp tube 7 and the coupling packing 8, the outer diameter of the straight tube lamp 3 and the frictional resistance of the inner rib 8d are reduced. The straight tube lamp 3 becomes difficult to insert.

  As a result of experimenting with the number of inner ribs 8d increased and decreased, the stability of the straight tube lamp 3 when it was fixed and the mountability of attaching the straight tube lamp 3 to the lamp tube unit 5 (the straight tube lamp 3 was inserted into the coupling packing 8) In order to maintain the fluidity of the air inside the lamp tube unit 5, good results are obtained when the number of the inner ribs 8 d is changed from six to ten, and eight is optimal. It was.

  Another embodiment of the coupling packing according to this embodiment will be described with reference to FIG.

  FIG. 8 shows a modification of the shape of the inner rib 8d for attaching the straight tube lamp 3 of the coupling packing 8 described above.

  The coupling packing 8 ′ includes an inner rib 8 e in an oblique direction on the inner side.

  In this way, the inner rib 8e provided in the coupling packing 8 ′ is not in a straight line but in an oblique direction, so that air fluidity is ensured and the lamp holder 6 is attached when the lamp holder 6 is mounted. More strength can be obtained with respect to the force applied to the central part of the cylindrical shape.
