Description

  The present invention relates to a socket for holding a straight tube illumination lamp and a lighting fixture using the socket.

  The lighting fixture is provided with a socket for supporting the base portion of the straight tube type lighting lamp. Here, in order to arrange a plurality of straight tube illumination lamps in the longitudinal direction, a connecting component for connecting sockets has been proposed (for example, see Patent Document 1). In the connecting component described in Patent Document 1, a socket that supports a base at the end of one straight tube lighting lamp is fitted on one side of the connecting component main body, and a base at the end of the other straight tube lighting lamp is used. The socket to support is inserted in the other side of a connection component main body.

  Further, there is a lamp socket (hereinafter also referred to as a common lamp socket) having a structure in which a straight tube fluorescent lamp can be attached to both surfaces of a lamp socket body (see, for example, Patent Document 2). In the technique described in Patent Document 2, a first structure in which a base of one end of a straight tube illumination lamp is attached to one end of a socket body is formed, and the other straight tube illumination lamp is disposed on the other end. A second structure to which a base at the end is attached is formed. Further, a lid is formed so as to partition the first structure side and the second structure side. In the technique described in Patent Document 2, the first structure, the second structure, and the lid are integrally formed.

Japanese Patent Laid-Open No. 10-2223015 (for example, see abstract) Japanese Patent No. 4295039 (for example, see FIG. 4)

  The technique described in Patent Document 2 is difficult to manufacture a lamp socket (hereinafter also referred to as a non-shared lamp socket) different from the shared lamp socket by diverting a member of the shared lamp socket. Specifically, in addition to the common lamp socket, a non-common lamp socket that supports the end portion of one straight tube illumination lamp and the other straight tube illumination lamp is attached to the lighting device. However, the common lamp socket is one in which the first structure, the second structure, and the lid are integrally formed. For this reason, in manufacturing the non-shared lamp socket that requires the first structure (or the second structure) and the lid, the shared lamp socket in which the second structure (or the first structure) is integrally formed. Cannot be used, and the manufacturing cost increases. In addition, there is a problem that the development cost increases because the effort for designing the pair of lamp sockets increases.

  The present invention has been made in order to solve the above-described problems, and provides a socket and a lighting apparatus using the same that can suppress an increase in the size of a lighting device and a cost increase. It is intended to provide.

  FIG. 9 is an exploded perspective view of the second socket 80 according to the present embodiment. The second socket 80 is attached to the second base 21b of the first straight tube illumination lamp 20A and the second straight tube illumination lamp 20B that is not attached to the first socket 30. It is. As shown in FIG. 9, the second socket 80 includes a casing 31c, a rotor 40c, two pin contact pieces 60C, and a lid 81.

The casing 31 c has the same shape as the first casing 31 a and the second casing 31 b of the first socket 30. The casing 31c is detachably attached to the lid 81. The rotor 40c has the same shape as the first rotor 40a and the second rotor 40b of the first socket 30. Furthermore, the pin contact piece 60C has the same shape as the second pin contact piece 60A and the third pin contact piece 60B.
Thus, the second socket 80 can be manufactured by diverting most of the components of the first socket 30. That is, the second socket 80 includes the first casing 31a (or the second casing 31b), the first rotor 40a (or the second rotor 40b), and the second socket of the first socket 30. The pin contact piece 60A (or the third pin contact piece 60B) can be used. Note that the opening T3 illustrated in FIG. 9 corresponds to the first opening T1 (or the second opening T2).

  The second socket 80 is different in shape from the lid 50 of the first socket 30 with respect to the lid 81. However, since the lid 81 has the same shape as the surface on one side of the lid 50 or the surface on the other side, the shape is different from the lid 50, but the design is easy. Yes.

[Effects of the first socket 30 and the second socket 80 according to the present embodiment]
In the first socket 30 according to the present embodiment, an outer shell is configured by the first casing 31a, the second casing 31b, and the lid 50. For example, the first casing 31a and the lid 50 are fitted so that the second pin contact piece 60A and the first rotor 40a are accommodated. Then, in a state where a part of the connecting portion 73 and the first pin receiving portion 72a are arranged on the first space S1 side through the slit 52, the other of the connecting portion 73, the second pin receiving portion 72b, and the third The second casing 31b and the lid 50 are fitted so that the pin contact piece 60B and the second rotor 40b are accommodated. Although this assembling method is an example, the first socket 30 can be assembled by fitting each member in this way.
And in the 1st socket 30 which concerns on Embodiment 1, even if it does not provide connection components like patent document 1, it can arrange | position so that two straight tube | pipe type illumination lamps may be located in a line in series. . For this reason, the enlargement of the longitudinal direction of the illuminating device 10 to which the 1st socket 30 is attached can be suppressed to the extent that a connection component becomes unnecessary.

  Since the 1st socket 30 concerning this embodiment can control the enlargement of the longitudinal direction of lighting installation 10, it can also improve the design nature.

  The first socket 30 according to the present embodiment does not have to be provided with a connecting part as in Patent Document 1, and accordingly, the first straight tube illumination lamp 20A and the second straight tube illumination lamp 20B. Can be brought closer. Thereby, the space | interval of the light emission surface of 20 A of 1st straight tube | pipe type illumination lamps and the light emission surface of 2nd straight tube | pipe type illumination lamp 20B can be closely approached, and it can suppress that an optical nonuniformity arises. .

  The first socket 30 according to the present embodiment is intended to reduce the time of the work for assembling the lighting device 10 by the amount of work for attaching the connecting parts and the two sockets to the lighting device 10 as in Patent Document 1. Can do. Thereby, the manufacturing cost of the illuminating device 10 can be suppressed.

  The first socket 30 according to the present embodiment can manufacture the second socket 80 by diverting the members constituting the first socket 30. That is, the second socket 80 includes the first casing 31a (or the second casing 31b), the first rotor 40a (or the second rotor 40b), and the second socket of the first socket 30. The pin contact piece 60A (or the third pin contact piece 60B) can be used. As described above, the first socket 30 can share most of the members with the second socket 80, and the manufacturing cost can be reduced accordingly. In addition, since most members can be shared, the burden of designing a structure different from that of the first socket 30 for the second socket 80 is suppressed, and the development cost can be suppressed.

The lid 81 of the second socket 80 is different in shape from the lid 50 of the first socket 30.
However, the lid body 81 can be diverted with the lid body 50 by folding the fitting portion 54 and the claw portion 55 on one surface of the lid body 50, for example. Thereby, it is not necessary to create the metal mold | die about the cover body 81, and the manufacturing cost can be suppressed by that much.
Further, even when the fitting portion 54 and the claw portion 55 are folded and not used, the lid 81 has the same shape as the one surface of the lid 50 or the other surface. Therefore, although the shape is different from that of the lid 50, the design is easy and the development cost can be suppressed.

  The first socket 30 according to the present embodiment has a first pin contact piece 70 and is electrically connected to the two straight tube illumination lamps 20A and 20B with one contact piece. It is comprised so that. For this reason, since the number of the electric wires connected to the 1st socket 30 can be reduced, connection failure can be reduced and quality can be aimed at by that much.
