  In the present embodiment, as shown in FIG. 1, a light source device 1 having an electrical light source is connected, and a circuit block 2 for lighting a light source, a circuit block 2 being housed and held, and a light source device 1 is provided with the instrument main body 3 which couple | bonds removably. Hereinafter, the vertical and horizontal directions are based on FIG. 1, and the direction perpendicular to the paper surface of FIG. Note that the above direction is defined for convenience of explanation, and does not necessarily match the direction in the actual use state.

The light source device 1 is a so-called straight tube LED lamp, and has a cylindrical light-emitting unit 11 that houses a plurality of light-emitting diodes (not shown) as light sources, and both ends of the light-emitting unit 11 in the axial direction. and a ferrule 1 2 provided respectively. At least a part of the outer peripheral surface of the light emitting unit 11 is made of a light-transmitting material so as to emit the light of the light emitting diode. As the light source, another electric light source such as an organic EL may be used instead of the light emitting diode. The light source device 1 is fixed to the fixture body 3 with the axial direction of the light emitting unit 11 directed in the left-right direction.

The light source device 1 is sized and shaped in accordance with a general straight tube fluorescent lamp, and can be mounted on a socket or the like to which a straight tube fluorescent lamp can be mounted instead of the fluorescent lamp. It has become. That is, the ferrule 1 2, two connecting pins 121 in the same size and shape and arrangement and the terminal pins projecting from the cap of a fluorescent lamp of the straight tube is projected. And the instrument main body 3 is hold | maintained one each in the shape which protrudes below in the left-right both ends of the main-body part 31 which accommodates and hold | maintains the circuit block 2 inside, for example in a rectangular parallelepiped box shape, for example. Socket 32. Each socket 32 each have the same structure as the known sockets corresponding to the fluorescent lamp of the straight tube, the light source device 1 by removably coupled to ferrule 1 2 one by one light source device 1 Holding means for holding The connection pins 121 and the sockets 32 are used only for mechanical holding and are not electrically connected to the light emitting diodes or the circuit block 2, and therefore may be formed of only an insulating material.

  The circuit block 2 includes a power conversion circuit that converts input AC power into appropriate power suitable for lighting the light source of the light source device 1 in a suitable case. The above power conversion circuit can be realized by a known rectifier circuit and step-down circuit, for example.

  Furthermore, the main body 31 of the instrument main body 3 holds a power line connecting portion 33 to which the other end of a power line (not shown) whose one end is connected to a power source (for example, a commercial power source) is connected. That is, the circuit block 2 is connected to the power supply via the power supply line connecting portion 33 and the power supply line. The power supply line connecting portion 33 can be realized by a known terminal structure such as a quick connection terminal or a screw terminal, for example, or a known connector may be used.

Here, the electrical connection between the light source device 1 and the circuit block 2 is achieved by the connection line 4. In the instrument body 3, for example, an insertion hole (not shown) through which the connection line 4 is inserted is opened on the lower surface of the body portion 31. One end of the connection line 4 is connected to the circuit block 2, and the other end is provided with a plug 51 as shown in FIG. On one of the light source device 1 ferrule 1 2 (non-light emitting portion) of (left side in FIG. 1) a receptacle 52 which the plug 51 is freely inserted and connected detachably is provided. The plug 51 and the receptacle 52 constitute a known connector, and the light source device 1 and the circuit block 2 are electrically connected to each other via this connector and the connection line 4.

  Hereinafter, a surplus length processing means for processing the surplus length of the connection line 4 which is a characteristic part of the present invention will be described. In the present invention, by providing the surplus length processing means, the shadow due to the connection line 4 is less likely to occur than when the surplus length of the connection line 4 is not processed and hangs down.

The present embodiment has a bobbin 6 that is rotatably supported with respect to the instrument body 3 as a surplus length processing means. As shown in FIGS. 3 and 4, the bobbin 6 has a cylindrical main body 61 and a plurality (three in the figure) that project from the main body 61 outward in the radial direction and sandwich the connecting wire 4. Part 62. The instrument body 3 has a cylindrical shape and is inserted into the bobbin 6 so as to pivotally support the bobbin 6, and two legs each connecting one end of the shaft part 34 to the body part 31. Part 35. That is, the extra length of the connection line 4 is wound around the main body 61 between the flanges 62 in the bobbin 6 so that the extra length of the connection line 4 does not block the light of the light source device 1. Can be suppressed (that is, the surplus length is processed). In the example of FIG. 1, a part of the bobbin 6 protrudes below the instrument body 3, and the user can rotate the bobbin 6 from below the instrument body 3. The bobbin 6 is positioned between the base 12 to which the plug 51 is connected and the circuit block 2, and is axial in the front-rear direction, which is a direction orthogonal to the direction in which the base 12 and the circuit block 2 are arranged. Is pointing. Therefore, if a sufficient frictional force is applied between the connecting wire 4 and the bobbin 6, by rotating the bobbin 6, the left side of the bobbin 6 (light source device 1 side) to the right side (circuit block 2 side). Alternatively, the slack of the connection line 4 can be moved in the opposite direction.

Further, it is conceivable to use the light source device 1 as the extra length processing means. For example, it provided with a groove 120 on the outer peripheral surface of the ferrule 1 2 as shown in FIG. 2, winding the extra length of the connection line 4 along the groove 120. That is, the bottom surface of the groove 120 serves as a winding portion, and the wall closer to the light emitting unit 11 with respect to the groove 120 (the right wall in FIG. 2) serves as a blocking convex portion. In this case, if a socket 32 that supports the light source device 1 so as to be rotatable around the axis of the light emitting unit 11 is used as indicated by an arrow A1 in FIG. 2, the plug 51 is inserted into the receptacle 52 (that is, the connection line to the light source device 1). 4), the connection line 4 can be wound up by rotating the light source device 1 relative to the instrument body 3. Since the socket 32 as described above can be realized by a well-known technique, detailed illustration and description thereof will be omitted.

  Further, as the extra length processing means, it is conceivable to provide a drawing means for drawing the extra length of the connection line 4 into the instrument body 3. As the pull-in means, for example, as shown in FIG. 5, a tension coil spring 7 having one end connected to the instrument main body 3 and the other end connected to the connection line 4 can be used. Alternatively, as shown in FIG. 6, the connection wire 4 may be formed in a coil shape, and may be drawn into the instrument body 3 by the elasticity of the connection wire 4 itself. Become.

  Further, as indicated by an arrow A2 in FIG. 7, the circuit block 2 can be displaced left and right with respect to the instrument body 3 (that is, in a direction in which the distance from the base 12 to which the connection line 4 is connected). Also good. That is, if the circuit block 2 is displaced to the right (that is, in the direction away from the base 12) after the connection of the connection line 4 is completed, the slack of the connection line 4 is eliminated, resulting in a surplus length. It is processed. That is, the circuit block 2 functions as extra length processing means. In this case, as shown in FIG. 8, it is desirable to provide the circuit block 2 with a knob 21 that projects downward from the instrument body 3 and receives an operating force. As a structure for connecting the circuit block 2 to the instrument body 3 so as to be displaceable, for example, a rail-like structure can be adopted, which can be realized by a well-known technique, and detailed illustration and description thereof will be omitted. In the example of FIG. 7, the instrument main body 3 is provided with a restricting convex portion 38 that restricts the movable range of the circuit block 2 in the right direction by coming into contact with the circuit block 2 from the right side.

  Further, as the surplus length processing means, as shown in FIG. 9, a winding convex portion 36 around which the surplus length of the connecting wire 4 is wound may be provided on the outer surface (lower surface in the drawing). . In order to prevent the wound connection wire 4 from falling off, as shown in FIG. 10, the distal end portion (lower end portion in the drawing) of the winding convex portion 36 has a cross-sectional shape more than other portions. It is desirable that a large flange 361 is provided.

  In addition, as shown in FIG. 11, in the state where the light source device 1 is removed, a plug holding portion 37 to which the plug 51 is detachably coupled may be provided in the instrument body 3 as indicated by an arrow A <b> 3 in FIG. 12. The plug holding portion 37 as described above may have, for example, a clip-like structure that elastically holds the plug 51, a structure that is coupled to the plug 51 by uneven engagement or fitting, and is similar to the receptacle 52. It is good also as a structure of. Furthermore, the circuit may be configured such that the output of power from the circuit block 2 to the connection line 4 is stopped during the period in which the plug 51 is held in the plug holding unit 37. As the above-described circuit, for example, a circuit including a switch that switches on / off depending on whether or not the plug 51 is held in the plug holding unit 37 can be considered. However, whether or not the plug 51 is connected to the light source device 1 can be detected by a well-known technique. Therefore, if the plug 51 is not connected to the light source device 1, the circuit block can be used even if it is not held by the plug holding unit 37. The output of power from 2 to the connection line 4 is preferably stopped.

  The various extra length processing means may be used in combination.
