Description

  The present invention relates to an illuminator including a light source body and an illuminating device using the illuminator.

  The lighting device is an important element that impresses the space, and various products are provided on the market. In addition, various products such as a rod-shaped fluorescent lamp, a spherical incandescent lamp, a spherical fluorescent lamp, and the like are provided on the market.

  Furthermore, as for the lighting device to which the illuminator is attached, a very large number of products rich in design are provided on the market.

  On the other hand, various standards exist for the size of the socket in the illuminator.

  Under such circumstances, with the change in lifestyle in recent years, an increasing number of users enjoy illumination by changing to an illuminator with less power consumption or replacing with an illuminator with a different color tone.

  However, if a lamp manufacturer tries to provide an illuminator suitable for a wide variety of lighting devices to the market, as described above, there are a large number of varieties, which makes inventory management complicated and has a sufficient cost. There is a problem that cannot be down.

  Under such background, Japanese Patent Application Laid-Open No. 2004-30994 proposes a lamp having a base having a different diameter. Such lamps having different diameters can be applied to lighting devices having different socket diameters, and thus have an advantage of reducing the number of varieties that must be stocked.

  FIG. 14 is a diagram showing a configuration of a lamp proposed by the above-mentioned document. 14A is an exploded perspective view, FIG. 14B is a partial cross-sectional view when the lamp body 101 is mounted on the small diameter socket 112, and FIG. 14C is a view where the lamp body 101 is mounted on the large diameter socket 113. It is a fragmentary sectional view at the time of doing.

  The lamp main body 101 has a large-diameter base part 103 and a small-diameter base part 104. In addition, a coil spring 109 is provided, and the small-diameter base portion 104 protrudes coaxially from the tip portion of the large-diameter base portion 103 by the elastic restoring force of the coil spring 109.

  When attaching the lamp main body 101 to the small diameter socket 112, the small diameter cap 104 is screwed into the small diameter socket 112. When the lamp body 101 is attached to the large-diameter socket 113, the large-diameter base 103 is screwed into the large-diameter socket 113.

  Incidentally, as described in “0028” of Document 1, the lead wire from the lamp body 101 is connected to the large-diameter base 103 and the center contact 110.

  Therefore, no lead wire is connected to the small diameter cap 104. For this reason, the lamp is not lit only by screwing the small-diameter base 104 into the small-diameter socket 112.

  Therefore, the flange piece 108 of the small-diameter base 104 is pressed against the rim flange 107 by the urging force of the spring 109 so that power can be supplied to the small-diameter base 104 via the large-diameter base 103. .

  However, in this configuration, it is possible to attach to sockets of different diameters, but the distance between the lamp body 101 and the central contact 10 is determined by the diameter of the socket. The distance between the lamp body 101 and the center contact 10 is increased by the length of. Therefore, the top of the lamp body 101 sometimes protrudes from the cover.

  Further, since the small-diameter base portion 104 does not have a configuration for restricting idle rotation with respect to the large-diameter base portion 103, when the lamp main body 101 is attached to the small-diameter socket 112, the lead may be broken.

JP 2004-30994 A

  Since the dimension between the lamp body and the base part electrically connected to the lamp body cannot be adjusted by itself, inconveniences as exemplified above occur.

  Then, an object of this invention is to provide the illuminator which enabled the dimension between these to be adjusted, and an illuminating device using the same.

  In order to solve the above-described problems, an invention relating to an illuminator adjusts a distance between a light source main body, a power receiving unit electrically connected to the light source main unit, and the light source main unit and the power receiving unit. And an adjustment unit.

  Since the illuminator has the adjusting unit, the dimension between the light source body unit and the power receiving unit electrically connected can be adjusted as appropriate, and convenience is improved.

    Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration of an illuminator 2 according to the present invention. FIG. 2 is a partial cross-sectional view of the illuminator 2. In the following description, a bulb-type E-type lamp will be described as an example, but the present invention is not limited by this configuration.

The illuminator 2 includes a light source main body 11, a power receiving unit 13, an adjustment unit 20, and the like. The adjusting unit 20 and the power receiving unit 13 constitute the above-described light bulb-shaped E base. Then, the bulb-shaped E base is expanded and contracted by the adjusting unit 20. By this expansion and contraction, the distance (neck length) between the light source main body 11 and the power receiving unit 13 can be adjusted.
Various light sources such as a rod-shaped fluorescent lamp, a spherical incandescent lamp, and a spherical fluorescent lamp can be applied to the light source body 11 in consideration of design and the like. The main body root portion 12 of the light source main body portion 11 is sealed.

  The power receiving unit 13 includes a screw-type base part 14, an insulator 15 provided inside the base part 14 to support the base part 14, and a contact 16 provided at the tip of the base part 14. ing.

  Such a power receiving unit 13 and contact 16 comply with the standard. A lead R1 from the light source body 11 is connected to the power receiving unit 13, and the other lead R2 is connected to the contact 16.

  The adjustment unit 20 includes an inner cylinder 30 fixed to the base portion 12 of the main body, an outer cylinder 40 that houses the inner cylinder 30 and slides in the vertical direction, and is provided at a lower end portion of the outer cylinder 40 to lock the inner cylinder 30. A positioning mechanism 50, a return mechanism 21 for urging the inner cylinder 30 toward the light source main body 11, and a lid 22 for restricting the inner cylinder 30 from coming out toward the light source main body 11. The return mechanism 21 can be a coil spring, rubber, or the like.

  The outer cylinder 40 is demonstrated with reference to Fig.3 (a). The outer cylinder 40 is formed on a cylindrical body 41 made of an insulating material such as a resin constituting the main body, a lock window 42 in which a positioning mechanism 50 provided on the lower end side is accommodated, and formed on the upper edge side of the lock window 42 to return. The lower end supporting portion 43 that supports the mechanism 21, the concave guide groove 44 that extends from the upper end of the cylindrical body 41 to the lower end supporting portion 43, the shaft hole 45 that forms the engagement hole of the swing shaft 53 of the positioning mechanism 50, and the like. .

  The lower end support 43 is formed in a ring shape and integrally with the cylindrical body 41, but may be formed separately from the cylindrical body 41 and integrated with an adhesive or the like.

  As shown in FIG. 3A, the positioning mechanism 50 includes a lever 51, a hook 52 with the upper end of the lever 51 facing the inner cylinder 30, a button 56 protruding from the lower end of the lever 51, and the lever 51. A swing shaft 53 that is swingably supported, a spring receiver 54 (see FIG. 2) fixed to the terrace 17 of the insulator 15, a lever biasing spring 55 that contacts the lever 51, and the like.

  The lever 51 is made of an elastically deformable material such as resin. When the lever 51 is attached to the outer cylinder 40, the swing shaft 53 is compressed and elastically deformed and engaged with the shaft hole 45. Since the swing shaft 53 is compressed and elastically deformed, the lever 51 can be easily mounted.

  The inner cylinder 30 will be described with reference to FIG. The inner cylinder 30 has an upper end support 31 that supports the return mechanism 21 at the upper end, a claw 32 formed near the lower end, a rib 33 that slides in the groove, and the like that is loosely fitted in the guide groove 44 of the outer cylinder 40. Yes. The inner cylinder 30 is formed of an insulating material such as resin.

  When the rib 33 is loosely fitted in the guide groove 44, the screwing force when the power receiving unit 13 is screwed into the power feeding unit (see FIG. 12) is transmitted from the inner cylinder 30 to the outer cylinder 40. In other words, the inner cylinder 30 is restricted from rotating with respect to the outer cylinder 40.

  2 and 3 show a case where one pair of rotation restricting mechanisms 39 is configured by one rib 33 and one guide groove 44, but a plurality of pairs of rotation restricting mechanisms 39 may be provided.

  When the hook 52 is engaged with the claw 32, the distance (neck length) between the light source body 11 and the power receiving unit 13 can be adjusted and maintained.

  FIG. 4 is a diagram for explaining the operation of the positioning mechanism 50. FIG. 4A shows a state where the neck length is extended by releasing the engagement between the hook 52 and the claw 32. FIG. 4B shows an operation state when the engagement between the hook 52 and the claw 32 is released. FIG. 4C shows a state in which the hook 52 is engaged with the claw 32 and the neck length is shortened.

  The hook 52 and the claw 32 are engaged by engaging the hook 52 with the claw 32 by gripping them and pushing them in against the elastic force of the return mechanism 21 (FIG. 4C). .

  Since the lever 51 is urged by the lever urging spring 55 so that the hook 52 is directed toward the claw 32, the engagement state between the hook 52 and the claw 32 is maintained, and the light source main body 11 and the power receiving unit 13 are maintained. The neck is locked in a short state.

  On the other hand, when the button 56 is pressed and the engagement between the hook 52 and the claw 32 is released (FIG. 4B), the inner cylinder 30 moves in the direction of coming out of the outer cylinder 40 by the elastic force of the return mechanism 21, and the light source The neck length between the main body 11 and the power receiving unit 13 is extended (FIG. 4A).

  Therefore, the use according to the form of the illuminating device used, such as the length and shape of the cover, becomes possible.

  Next, another embodiment will be described. In the above description, since only one claw 32 is provided, the neck length of the light source main body 11 and the power receiving unit 13 can be adjusted only in two stages (locked state and unlocked state).

  However, as shown in FIG. 5, a plurality of (two in FIG. 5) claws may be provided. By providing a plurality of claws, the neck length can be adjusted in a plurality of stages, and can be set to a neck length suitable for the lighting device to be mounted.

  In the above description, the claw 32 protrudes from the outer wall surface of the inner cylinder 30, but may be a groove-like claw 32 a recessed in the outer wall surface as shown in FIG. 6, for example.

  In the case of this configuration, even when the return mechanism 21 is formed by a coil spring, the coil spring and the claw 32a do not interfere with each other, so that the dimensions of the inner cylinder 30 and the like can be shortened, and the height of the adjustment portion can be shortened. There are advantages.

  In the above description, when the lever 51 is mounted on the outer cylinder 40, the swing shaft 53 is compressed and elastically deformed and engaged with the shaft hole 45. However, since the allowable amount of compressive elastic deformation of the swing shaft 53 is limited, there may be a case where the swing shaft 53 and the shaft hole 45 cannot be brought into a sufficiently engaged state.

  In such a case, for example, as shown in FIG. 7, an oval through hole 57 is formed so as to penetrate the swing shaft 53, so that the oval through hole is mounted when the lever 51 is attached to the outer cylinder 40. 57 may be deformed as indicated by a dotted line (that is, the left and right wall portions 58 are deformed so as to approach each other).

  Since the deformation amount of the oval through hole 57 is added to the engagement amount between the swing shaft 53 and the shaft hole 45, the engagement between the swing shaft 53 and the shaft hole 45 is brought into a sufficiently engaged state. be able to.

  In the above description, the lever biasing spring 55 is used to maintain the lever 51 in the initial state, and the lever biasing spring 55 is accommodated in the spring receiver 54 fixed to the terrace 17 of the insulator 15. .

  However, the present invention is not limited to this, and may be configured as shown in FIGS. 8 and 9, for example.

  In the configuration shown in FIG. 8, a spring receiving plate 54b corresponding to the action of the spring receiver 54 is provided, a spring receiving hole 54c is formed in the button 56 of the lever 51, and the lever biasing spring 55 is accommodated in the spring receiving hole 54c. To do.

  This configuration has an advantage that the step of fixing the spring receiver 54 to the terrace 17 can be reduced because the spring receiving plate 54b can be formed at the same time when the outer cylinder 40 is formed by resin molding or the like.

  The configuration shown in FIG. 9 uses a torsion spring 55 b instead of the lever biasing spring 55. A locking hole 55c for locking one end of the torsion spring 55b is formed in the lock window 42. Further, a locking hole 55 d for locking the other end of the torsion spring 55 b is formed in the lever 51, and the annular portion 55 e of the torsion spring 55 b is inserted into the swing shaft 53.

  Thereby, even if the lever 51 tilts about the swing shaft 53, the torsion spring 55b acts to return the lever 51 to the initial state.

  In this configuration, there is an advantage that the step of fixing the spring receiver 54 to the terrace 17 can be omitted, and the initial state of the lever 51 can be parallel to the wall surface of the outer cylinder 40, and the hook 52 of the lever 51 is connected to the inner cylinder 30 side. There is an advantage that can be prevented from falling down.

  In the above description, the positioning mechanism 50 is configured to include the lever 51 and the like, but the present invention is not limited to this, and may be configured as shown in FIG. The configuration shown in FIG. 10 is a configuration in which lateral grooves 59a to 59c along the circumferential direction are provided in the guide groove 44 of the outer cylinder 40, and the rib 33 of the inner cylinder 30 is locked to the lateral grooves 59a to 59c. ing.

  That is, FIG. 10A and FIG. 10B show a case where the height h of the lateral groove 59a is uniform. FIG. 10A shows a case where the horizontal groove 59a is formed horizontally, and FIG. 10B shows a case where the horizontal groove 59b is formed so as to climb upward (the angle θ indicates this gradient).

  In FIG. 10C, a circular pocket 59c is provided at the end of the lateral groove 59d. The height of the lateral groove 59d is set to a dimension that is appropriately smaller than the height of the rib 33, and the pocket 59c is formed to a dimension that is appropriately larger than the lateral groove 59d. Has been.

  In the present specification, a configuration in which the lateral groove 59b climbs upward and a configuration in which a circular pocket 59c is provided at the tip of the lateral groove 59d are collectively referred to as a rib retaining mechanism.

  With such a configuration, the screwing force can be transmitted from the inner cylinder 30 to the outer cylinder 40 without the inner cylinder 30 idling without using the lever 51 or the like as described above, and a desired neck length can be obtained. It is possible to adjust and maintain the position.

  Further, as shown in FIG. 10B, when the lateral groove 59b is inclined to the light source body 12 side, the inner cylinder 30 is urged toward the light source body 12 by the return mechanism 21, so that the rib There is an advantage that 33 is difficult to be removed from the lateral groove 59b.

  Furthermore, if a circular pocket 59c is provided at the end of the lateral groove 59d as shown in FIG. 10 (c), the rib 33 is not easily pulled out when it fits into the pocket 59c, so that the reliability of maintaining the position of the neck length is improved. To do.

  Next, the illuminating device using such an illuminator 2 is demonstrated. FIG. 11 shows a partial cross-sectional view of the illumination device 4 to which the illuminator 2 is attached. FIG. 12 is a cross-sectional view showing a state when the light source body 12 is attached to the lighting device 4. The illuminating device 4 includes a power feeding unit 61, a cover 52, and the illuminator 2. In addition, about the element demonstrated so far, the same code | symbol is attached | subjected and description is abbreviate | omitted suitably.

  The cover 62 covers the light source main body 12 so that the light source main body 12 does not come into contact even when the adjustment unit 20 adjusts the distance between the light source main body 12 and the power receiving unit 13.

  That is, even if the distance between the light source body 12 and the power receiving unit 13 is adjusted by the positioning mechanism 50 of the adjustment unit 20, the light source body 12 can be held at a position where it does not contact the cover 62.

  The procedure in the case of attaching the illuminator 2 to such an illuminating device 4 is demonstrated according to FIG. FIG. 12 is a cross-sectional view showing a state when the light source body 12 is attached to the lighting device 4.

  First, the neck length of the illuminator 2 is extended, and the light source body 12 is gripped in this state. Then, the power receiving unit 13 is rotated while reaching the power feeding unit 61. Since a spiral groove is formed in the base part 14 and the power feeding part 61 of the power receiving part 13, the power receiving part 13 and the power feeding part 61 are screwed together by rotating the illuminator 2.

  Thus, even when the cover 62 has a deep structure, the light source body 12 can be easily attached because the neck length is long.

  As shown in FIG. 13, when the light source body 12 is attached and the top of the light source body 12 protrudes from the cover 62, the light source body resists the force of the return mechanism 21. The unit 12 is pushed into the power receiving unit 13 side. As a result, the positioning mechanism 50 functions and the neck length can be adjusted at a position where the light source body 12 does not hit the cover 62. Therefore, there is no loss of aesthetics.

  In addition, the adjustment unit 20 includes the inner cylinder 30, the outer cylinder 40 into which the inner cylinder 30 is inserted, and the rotation restriction mechanism 39 that restricts the inner cylinder 30 from idling with respect to the outer cylinder 40. There is no possibility that the inner cylinder 30 is idle and the leads R1 and R2 are threaded. Therefore, reliability is improved.
