Further, the frame 220 formed of metal is easier to mold than a non-combustible material such as glass. Therefore, it can be made to be the same shape as the standard instrument put on side by the frame side 220, and the standard instrument and the emergency combined use instrument can be made to have the same design in the cross-sectional shape in the short direction Y. In the same manner, the design is similar to the dimensions of the outer shell, and there may be unevenness and gaps due to connection of parts in part.

In the present embodiment, the light source unit 200 includes the power supply device 260, and the power supply device 260 is for the light emitting unit that connects the first input connector 262b connected to the regular connector 134 of the terminal block 130 and the power supply device 260 and the light emitting unit 210. A second input connector 263 a is provided on the light emitting unit wire 263. Therefore, the first input connector 262b can supply power from the commercial power supply to the power supply device 260 during normal use, and the second input connector 263a supplies power from the emergency power supply device 140 to the light emitting unit 210 during an emergency. As the light source unit 200 can be used, the light source unit 200 can be used both in normal use and in emergency.
The first input connector 262b and the second input connector 263a may be connectors of different shapes. By using a connector of another shape, it is possible to prevent erroneous attachment such as connecting the regular connector 134 to the second input connector 144, and to suppress failure of the light source unit 200.

  In the present embodiment, the instrument body 100 accommodates the terminal block 130, the emergency power supply device 140, the storage battery 150, and the inspection switch 160 such that they are disposed on one end side from the approximate center of the accommodation recess 110 in the longitudinal direction X.

The pair of frame side portions 412 are formed so as to approach each other as they project downward in the downward direction Z1. The frame 410 is formed of a metal member such as an aluminum member. The frame 410 may be formed, for example, by bending a metal plate, or may be formed by extrusion molding or injection molding.

  The cover 420 has a cylindrical shape, and the light emitting portion 430 and the reinforcing frame 440 are disposed inside. The cover 420 is formed of a nonflammable material such as glass.

  The light emitting unit 430 is mounted on a substrate 432 on which a plurality of light emitting elements 431 are formed to be long.

  The reinforcing frame 440 is formed to be long, to which the light emitting unit 430 is attached, and is housed inside the cover 420 in a state where the light emitting unit 430 is attached. The reinforcing frame 440 is a first holding portion that holds the cover 430 in the longitudinal direction X.

  The lids 450 are respectively disposed at both ends of the light source unit 400 in the longitudinal direction X, and the reinforcing frame 440 is engaged, and the ends of the cover 430 in the longitudinal direction X are held. The lid 450 is a second holding portion that holds an end of the cover 430 in the longitudinal direction X.

  In the lighting fixture 300 of the present embodiment, the cover 430 of the light source unit 400 is formed in a cylindrical shape, so that the strength of the cover can be increased and it can be made difficult to be detached.

  Further, in each of the above-described first embodiment and second embodiment, although the specification has been described in which the spring 120 is provided in the tool main body 100 and the connection fitting 250 is provided in the light source unit 200 The light source unit 200 may be configured to include the spring 250.

  Moreover, although the truss-shaped lighting fixture attached to a ceiling etc. was demonstrated, it is not restricted to a truss shape, the shape of the fixture main body may be a reverse Fuji shape which has a reflection part, and the shape is not limited if it is a lighting fixture.

  Furthermore, Embodiment 1 and Embodiment 2 can be combined as appropriate. Moreover, it is also possible to extract and combine a part of Embodiment 1 and Embodiment 2. Furthermore, the present invention is not limited to the first embodiment and the second embodiment, and can be appropriately modified.
