  Conventionally, the baton 3 to which the baton holder 4 is coupled, the circuit holder 2, and the light source holder 1 are arranged in a straight line when viewed from the axial direction of the baton 3. Was getting bigger.

  This invention is made | formed in view of the said reason, The objective is to provide the lighting fixture which can make the protrusion dimension from a baton small.

  A lighting fixture of the present invention includes a light source holder that holds an electrical light source, a circuit holder that holds a lighting circuit that lights the light source, and a baton holder that is coupled to a baton, and at least a part of the circuit holder is , Located on the opposite side of the light source holder across the baton.

  The lighting apparatus includes an arm having one end connected to the circuit holder, the light source holder being rotatably connected to the arm, and the rotating shaft of the light source holder with respect to the arm. It is desirable that the projection size of the light source holder is a projection size of the arm from the rotating shaft and is not more than the projection size in a direction perpendicular to the direction in which the light source block and the circuit holder sandwich the baton. .

  According to the present invention, the projecting dimension from the baton can be reduced as compared with the case where the entire circuit holder and the light source holder are located on the same side with respect to the baton.

It is a front view which shows embodiment of this invention. It is a front view which shows the example of a change same as the above. It is a front view which shows a prior art example.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  In the present embodiment, as shown in FIG. 1, a light source holder 1 that holds an electrical light source, a box-shaped circuit holder 2 that houses and holds a lighting circuit that turns on the light source, and a baton that is coupled to a baton 3. A holder 4.

  As the light source, a known light source such as a light emitting diode or a discharge lamp can be used. When a direct-current light source such as a light emitting diode is used as the light source, for example, a direct-current power supply circuit that converts alternating-current power input from the outside into appropriate direct-current power can be used as the lighting circuit. When a discharge lamp is used as the light source, the lighting circuit can be realized using, for example, a known electronic ballast. In any case, since the light source and the lighting circuit can be realized by a well-known technique, detailed illustration and description are omitted.

  The light source holder 1 is a reflector (not shown) that distributes light from the light source in a predetermined direction 61 or a light source as viewed from the direction 61 in which the light from the light source is made of a light-transmitting material. A light-transmitting cover (not shown) for protection is provided.

  Further, the baton holder 4 is composed of a U-shaped metal fitting whose both ends are fixed to other parts (for example, the circuit holder 2) by appropriate means such as screwing, and between the other parts. Hold the baton 3. Alternatively, the baton holder 4 may have a clip-like structure that elastically clamps the baton 3 or a giant vise-like structure that obtains a binding force to the baton 3 by tightening a screw. In the case where the baton holder 4 has a clip-like structure or a giant clam vise-like structure, all or part of the baton holder 4 may be formed continuously in another part (for example, the circuit holder 2). it can. Further, a plurality of baton holders 4 may be provided in the axial direction of the baton 3 (direction perpendicular to the paper surface of FIG. 1).

  The circuit holder 2 may be comprised with the metal plate, and may be comprised with the synthetic resin. In addition, the circuit holder 2 is integrally formed with an arm 5 that supports the light source block 1. For example, the arm 5 holds the light source holder 1 from both sides in a direction parallel to the central axis of the baton 3 (hereinafter simply referred to as “baton 3”) to which the baton holder 4 is coupled (a direction perpendicular to the paper surface of FIG. 1). It is a shape to sandwich. The light source holder 1 is connected to the arm 5 so as to be rotatable around a rotation axis 10 parallel to the central axis of the baton 3. That is, by rotating the light source holder 1 with respect to the arm 5, the light irradiation direction of the light source indicated by the arrow 61 in FIG. The connection as described above may be realized by inserting a shaft convex portion provided on one of the light source holder 1 and the arm 5 into a bearing hole provided on the other, or provided on the light source holder 1 and the arm 5. You may implement | achieve by inserting a cylindrical-shaped axis | shaft rod into the oval-shaped through hole.

  More specifically, the arm 5 has a main body portion 51 connected to the circuit holder 2 and a light source holder connecting portion 52 connected to the light source holder 1. The main body 51 is long in the direction orthogonal to the rotation axis 10 (the left-right direction in FIG. 1), and one end in the longitudinal direction (the left end in FIG. 1) is connected to the circuit holder 2. Further, the light source holder connecting portion 52 crosses the longitudinal direction of the main body 51 from the other end in the longitudinal direction of the main body 51 (the right end in FIG. 1) and the rotating shaft 10 (in FIG. 1). The light source holder 1 is connected to the tip (upper end in FIG. 1). That is, the arm 5 has an L shape when viewed from the direction orthogonal to the rotation shaft 10 (that is, the direction orthogonal to the paper surface of FIG. 1). Further, the baton holder 4 is located on the same side (upper side in FIG. 1) as the protruding direction of the light source holder connecting portion 52 with respect to the main body portion 51. Thereby, the central axis of the baton 3 and the rotating shaft 10 are aligned in the longitudinal direction of the main body 51 (the left-right direction in FIG. 1). Further, the circuit holder 2, the baton holder 4, and the light source holder coupling portion 52 of the arm 5, respectively, with respect to the main body portion 51 of the arm 5 in the above-described rotation axis 10 and the longitudinal direction of the main body portion 51 of the arm. They are perpendicular to each other and project to one side common to each other (upper side in FIG. 1) and do not project to the other side (lower side in FIG. 1). That is, the circuit holder 2 is located on the opposite side of the light source holder 1 with the baton 3 interposed therebetween.

  Further, the projecting dimension of the light source holder 1 from the rotating shaft 10 (that is, the radius of the circle 62 indicated by a one-dot chain line in FIG. 1) is the projecting dimension of the arm 5 from the rotating shaft 10 and is a circuit. The holder 2 and the light source holder 1 are set to have a projecting dimension or less in a direction (downward direction in FIG. 1) perpendicular to the direction in which the baton 3 is sandwiched (left-right direction in FIG. 1). Therefore, even if an obstacle (not shown) is in contact with the edge of the arm 5 in the above direction (lower edge in FIG. 1), the obstacle does not interfere with the light source holder 1. The rotation range is not narrowed.

  According to the above configuration, the projecting dimension from the baton 3 is made smaller than when the entire circuit holder 2 and the light source holder 1 are located on the same side (for example, the right side in FIG. 1) with respect to the baton 3. Can do.

  For example, when the light source holder 1 is positioned on the right side of the baton 3 as shown in FIG. 1, reducing the protruding dimension from the baton 3 as described above means downsizing in the left-right direction.

  In addition, the shape of each part is not restricted above, For example, as shown in FIG. 2, the shape of the circuit holder 2 is good also as a shape bent so that the baton 3 may be pinched | interposed between the main-body parts 51 of the arm 5. As shown in FIG.
