  The lighting fixture in this embodiment is as shown in FIG. 3, for example. Specifically, the lamp comprises an elongated straight tube type lamp, a socket 16 for mounting the lamp, a lighting circuit (not shown in particular) for supplying power to the lamp through the socket 16, and a lighting fixture main body 15 for holding the socket 16. It is.

  The lamp is an LED lamp 10 in which LED modules 12 in which light-emitting diodes 11 (LED elements) are arranged in the axial direction (longitudinal direction) are housed in a tubular, light-transmitting container, and the direction is perpendicular to the axial direction. Is irradiated with light from the light emitting diode 11. Further, the LED lamp 10 has a base 13 at each end in the axial direction, and two base pins 14 project from the end face of each base 13 along the axial direction. In addition, although the nozzle | cap | die 13 uses the substantially same thing as the nozzle | cap | die (G13 type | mold) of a fluorescent lamp lamp, you may use the nozzle | cap | die 13 other than G13 type | mold.

  By attaching the bases 13 to the sockets 16 of the luminaire main body 15, the LED lamp 10 is held between the two sockets 16 in the axial direction via the bases 13 at both ends. At that time, the cap pin 14 is inserted into an insertion port (not shown) of the socket 16, and power is supplied to the lamp 10 from the lighting circuit. In the following description, the lamp 10 means the LED lamp 10 except for a special case such as when distinguishing an LED lamp from a fluorescent lamp.

  Further, the lamp 10 is connected to another lamp 10 by a connector 1, and the connector 1 is formed of a cylindrical main body as shown in FIG. At both ends of the main body of the connector 1, a base receiving portion 2 into which the base 13 is inserted and an insertion opening 4 into which the base pin 14 is inserted are provided, and each insertion opening 4 is provided inside the main body. The conductive pins 5 are electrically connected to each of the cap pins 14 inserted from the above.

  The base receiving portion 2 includes a substantially circular receiving surface 2a with which the end face of the base 13 is in contact, and a cylindrical portion 3 that protrudes in the axial direction from the outer periphery of the receiving surface 2a and with which the peripheral surface of the base 13 is in contact. Have. And the cylinder part 3 is equipped with the nail | claw 3a in the internal peripheral surface, and when the end surface of the nozzle | cap | die 13 contact | abuts to the receiving surface 2a, as shown in FIG. While being abutted, the claw 3 a is fitted into a groove formed on the peripheral surface of the base 13.

  In addition, the cylinder part 3 improves the holding power with respect to the lamp | ramp 10 of the nozzle | cap | die receiving part 2, and if the nozzle | cap | die receiving part 2 is provided with the receiving surface 2a at least, what does not have the nail | claw 3a in the cylinder part 3 is used. Of course, the thing without the cylinder part 3 may be sufficient.

  In addition, two insertion openings 4 are provided on the receiving surface 2a of the base receiving portion 2 in the same arrangement as the base pins 14 on the end face of the base 13, and when the base 13 is brought into contact with the base receiving portion 2. The base pins 14 are respectively inserted into the base plate. The cap pins 14 inserted into the insertion port 4 are electrically connected to the conductive member 5, respectively. The conductive member 5 is a lamp in which the cap pin 14 of the lamp 10 is held by another cap receiver 2. It is electrically connected to the ten cap pins 14.

  That is, when the lamps 10 are respectively attached to the bases 2, the base pins 14 of the lamps 10 are electrically connected to the conductive members 5, so that the lamps 10 are electrically connected to each other via the conductive members 5. The two lamps 10 are connected in series. The insertion port 4 is not limited to one provided for each cap pin 14, but more than the cap pin 14 of the lamp 10, or an annular or arc shape around the axis of the main body on the receiving surface 2a. It may be provided.

  In this way, by connecting the plurality of lamps 10 with the connector 1, the plurality of lamps 10 become one lamp 10 connected in series, and the total length of the lamp 10 attached to the luminaire main body 15 is easily changed. be able to. That is, by changing the number of lamps 10 connected via the coupler 1, the brightness of the lighting fixture can be easily changed and adjusted. Therefore, at least one type of LED lamp 10 is manufactured, and an increase in cost can be suppressed.

  The connector 1 is not limited to an I-shape in which the base receiving portions 2 are provided at both ends of the main body, but may be any one having at least two base receiving portions 2. For example, as shown in FIG. 4, an L-shape in which the direction of the base receiving part 2 is substantially orthogonal, or a virtual straight line that includes three base receiving parts 2, two of which face each other and the other connects the two. In addition, there is a T-shape or the like located between the two.

  In addition, the connector 1 may be a rectangular body such as a cube. For example, as shown in FIG. 5, a cross-shaped one provided with a base receiving part 2 on each of the four opposing surfaces, a T-shaped connecting part, and a base receiving part 2 provided in three directions substantially orthogonal to each other. There are also things.

  By using the connector 1 having such a shape, for example, as shown in FIG. 6, the lamp 10 can be arranged in a shape other than a straight line such as arranging the lamp 10 along four sides of a square. Since the lamp 10 can be connected to a shape other than a straight line and can be arranged, the existing lamp 10 such as a straight tube type can be used without newly producing the lamp 10 bent into an L shape or a T shape. The lamp 10 can be arranged in an L shape or the like simply by connecting with the connector 1.

  In addition, when the direction of the base receiving part 2 intersects, the angle may be other than 90 degrees, and the arrangement, the number, etc. of the base receiving part 2 are not limited to the illustrated configuration and are appropriately set.

  In addition, there is a configuration in which the attachment 1 can be attached to the luminaire main body 15 via the attachment portion by providing the attachment 1 at least with the attachment 1. For example, as shown in FIG. 7, a holding portion 17 provided in the lighting fixture body 15 and having an opening, and a holding in which the tip is held by the holding portion 17 by being inserted into the opening of the holding portion 17 provided in the connector 1. There are projections 6 (mounting portions) and the like.

  And since the connected lamp 10 is hold | maintained at the luminaire main body 15 via the connection tool 1 by attaching the linking tool 1 to the luminaire main body 15 via an attachment part, respectively, The wobble can be suppressed.

  Note that the attachment portion attaches a holding clip made of a leaf spring or the like provided on the luminaire main body 15 or an L-shaped fitting provided on the connector 1 to the luminaire main body 15 with a member such as a screw or a bolt nut. The thing etc. may be sufficient. In particular, the attachment portion is not limited to the illustrated configuration, but it is preferable that the connector 1 is detachably attached to the luminaire main body 15. Of course, the attachment portion may be one that fixes the connector 1 to the luminaire main body 15 such as one in which a metal fitting is driven into the luminaire main body 15 with a screw or the like, or one that is attached by bonding.

  Further, the connector 1 may also serve as the socket 16. In this case, for example, as shown in FIG. 8, from the lighting circuit via the connector 1 positioned at both ends of the connected lamps 10. Electric power can be supplied to the lamp 10.

  Further, as shown in FIG. 9, a light emitting diode 7 is provided in the middle of the conductive member 5, and a light transmitting portion 8 made of a light transmitting panel or the like that transmits light of the light emitting diode 7 to the outside is provided in the main body. The light-emitting diode 7 of the coupler 1 may also emit light when lit.

  In this case, the light transmitted from the light transmitting portion 8 does not darken the space between the lamps 10 where the couplers 1 are located, making the couplers 1 inconspicuous, and the appearance of the lamps 10 arranged in a row is united. It is obtained. Note that the number of the light emitting diodes 7 provided in the connector 1 is not limited to one, and a plurality of light emitting diodes 7 may be provided along the entire circumference or the axial direction of the main body. May be.

  Further, a rotation mechanism 9 for rotating the lamp 10 held in the base receiving part 2 in the circumferential direction is provided, and the lamp 10 is rotated together with the base receiving part 2 by the rotation mechanism 9 as shown in FIG. You may change the direction of the light irradiated.

  The rotation mechanism 9 includes, for example, a guide rail formed in an annular shape around the axis of the connector 1 and a claw that slides along the guide rail, or a shaft member that is substantially concentric with the shaft of the connector 1. There are those that are provided and supported rotatably in the circumferential direction. And since it becomes possible to change the direction of the irradiation light of the lamp | ramp 10 with the rotation mechanism 9, it can adjust easily the light distribution of the lamp | ramp 10 connected, without adding a light-guide plate, a reflecting plate, etc. to a lighting fixture. This is preferable.

  Further, the rotation mechanism 9 may change the arrangement of the lamps 10. For example, another lamp 10 can be rotated about a straight line in which two lamps 10 are arranged as an axis, such as a T-shaped one shown in FIG. 11, or in the middle of two bases 2 as shown in FIG. Some of them have a rotation mechanism 9 and can be switched between an L shape and an I shape. Of course, a plurality of rotation mechanisms 9 may be provided so that the arrangement of the insertion opening 4 on the base receiving part 2 and the position of the base receiving part 2 can be changed.

  In other words, the rotating mechanism 9 distributes the light of the connected lamps 10 such as the one that rotates the lamps 10 by the base receiving part 2 and the one that changes the positions of the connected lamps 10 relative to each other or the mounting part of the lamps 10. Is to adjust.
