Further, the emergency lighting fixture 10 is provided with a flat portion 9 at a portion where the fixing member 7 is attached on the peripheral wall 8 of the case 11. Thereby, in the emergency lighting fixture 10, compared with the emergency lighting fixture of a prior art example, it becomes possible to make the opening area of the instrument main body 1 small. Therefore, the emergency lighting fixture 10 can be downsized as compared with the conventional emergency lighting fixture.

  As shown in FIGS. 1 and 4, the substrate 23 is arranged so that the first normal line on one surface in the thickness direction of the substrate 23 and the second normal line on one surface in the thickness direction of the flat portion 9 are parallel to each other. ing. In short, the substrate 23 is arranged so that the thickness direction of the substrate 23 and the thickness direction of the flat portion 9 are parallel to each other.

It becomes possible. Therefore, in the emergency lighting apparatus 10, compared to the case where the substrate 23 is arranged so that the first normal line of the substrate 23 and the second normal line of the flat portion 9 are orthogonal to each other, a ground formed in advance on the substrate 23 is formed. It is possible to secure a large amount (not shown). As a result, in the emergency lighting apparatus 10, for example, the power supply device 6 generates the substrate 23 as compared with the case where the substrate 23 is arranged so that the first normal line of the substrate 23 and the second normal line of the flat portion 9 are orthogonal to each other. It is possible to further suppress noise. The substrate 23 is more preferably arranged so that the first normal line of the substrate 23 and the second normal line of the flat portion 9 are completely parallel to each other.

  Although the board | substrate 23 is arrange | positioned so that the 1st normal line of the board | substrate 23 and the 2nd normal line of the flat part 9 may become parallel, it is not restricted to this arrangement | positioning. For example, as illustrated in FIG. 6, the substrate 23 may be disposed so that the first normal line of the substrate 23 and the second normal line of the flat portion 9 are orthogonal to each other. In short, the substrate 23 may be arranged so that the thickness direction of the substrate 23 and the thickness direction of the flat portion 9 are orthogonal to each other. In this case, in the emergency lighting apparatus 10, the first surface of the substrate 23 is compared with the case where the substrate 23 is arranged so that the first normal line of the substrate 23 and the second normal line of the flat portion 9 are parallel to each other. As the first electronic component mounted on the electronic component, it is possible to employ an electronic component having a higher height. The substrate 23 is more preferably arranged so that the first normal line of the substrate 23 and the second normal line of the flat portion 9 are completely orthogonal to each other, but the substrate 23 is flat with the first normal line of the substrate 23. You may arrange | position so that the 2nd normal line of the part 9 may cross substantially orthogonally. The term “substantially orthogonal” means, for example, that the angle formed by the first normal line of the substrate 23 and the second normal line of the flat portion 9 intersects at an angle in the range of 85 degrees to 89 degrees.

  The case 11 is formed in a cylindrical shape by a single plate material 57, but is not limited thereto. For example, as shown in FIG. 7, the case 11 may be formed in a cylindrical shape by combining a first plate member 51 and a second plate member 52. For example, the case 11 is formed in a cylindrical shape by combining a first plate member 51 that is a plate member obtained by dividing the plate member 57 and a second plate member 52 that is the remaining plate member obtained by dividing the plate member 57. May be. In this case, in the emergency lighting apparatus 10, it is possible to improve workability for producing the case 11 as compared with the case where the case 11 is formed in a cylindrical shape by the single plate member 57. Further, in the emergency lighting apparatus 10, it is possible to suppress the restoring force of the case 11 caused by the plate material 57 as compared with the case where the case 11 is formed in a cylindrical shape by the single plate material 57.

  Each of the first plate member 51 and the second plate member 52 is configured to form a cylindrical case 11 with the first plate member 51 and the second plate member 52.

  The portions other than the flat portion 9 in the peripheral wall 8 of the case 11 are formed in an arc shape in plan view, but are not limited to this shape. Sites other than the flat portion 9 in the peripheral wall 8 of the case 11 may be formed in a polygonal shape in a plan view as shown in FIG. 9, for example. In this case, in the emergency lighting apparatus 10, the opening area of the apparatus main body 1 can be further reduced as compared with the case where the portion other than the flat portion 9 in the peripheral wall 8 of the case 11 is formed in an arc shape in plan view. It becomes possible. Therefore, in the emergency lighting device 10, it is possible to further reduce the size compared to the case where the portion other than the flat portion 9 in the peripheral wall 8 of the case 11 is formed in an arc shape in plan view. Moreover, in the emergency lighting fixture 10, compared with the case where parts other than the flat part 9 in the peripheral wall 8 of the case 11 are formed in an arc shape in plan view, the restoring force of the case 11 caused by the plate material 57 is suppressed. Is possible.

  In addition, although the emergency lighting fixture 10 is what is called a special-purpose emergency lighting fixture which makes the light emission part 2 light-emit in an emergency, it is not restricted to this. The emergency lighting fixture 10 may be, for example, a so-called combination type emergency lighting fixture that causes the light emitting unit 2 to emit light in a normal time and an emergency time. The normal time means a time other than emergency.

  Moreover, although the electrical connection relationship of the some storage battery 4 is series connection, it is not restricted to this connection. A parallel connection may be sufficient as the electrical connection relationship of the some storage battery 4, for example. Moreover, the electrical connection relationship of the some storage battery 4 may be the connection which combined the serial connection and the parallel connection, for example. Although the number of the storage batteries 4 is plural, one may be sufficient.

The fixing member 7 is configured to be attached to the peripheral wall 8 of the case 11. The peripheral wall 8 of the case 11 is provided with a flat portion 9 at a portion where the fixing member 7 is attached. Thereby, in the emergency lighting fixture 10, compared with the emergency lighting fixture of a prior art example, it becomes possible to make the opening area of the instrument main body 1 small.
