  As shown in FIG. 1, lighting fixture 100 according to the present embodiment is attached to a mounting surface 200 such as a ceiling, and has a flat secondary battery 10 (an example of a battery on a flat plate) mounted thereon. The lighting device 20 includes a lighting circuit board 30 that turns on a light source with 10 electric power. The luminaire 100 is characterized in that, when attached to the attachment surface 200, the secondary battery 10 and the lighting circuit board 30 are arranged so as to be substantially parallel to the attachment surface 200. Therefore, the height H of the luminaire 100 can be further reduced, and a luminaire having a sense of unity with the ceiling surface with less protrusion from the ceiling surface can be provided.

  The luminaire 100 is, for example, a luminaire 100 that is attached to a ceiling surface as an example of the attachment surface 200. The luminaire 100 is equipped with a secondary battery 10, and normally the lighting device 20 is powered by an external power source such as a commercial power source. This is an emergency lighting device that charges the secondary battery 10 and lights the light source with the power of the secondary battery 10 charged by the lighting device 20 in the event of an emergency such as a power failure of the commercial power supply.

  The structure of the lighting fixture 100 which concerns on this Embodiment is demonstrated using FIGS.

  The lighting device 20 includes a unit case 50, and components and the like constituting the lighting device 20 are mounted on the unit case 50.

  The unit case 50 includes a lighting circuit board 30, a power terminal block 60, an LED 70 (an example of a light source), a plurality of mounting portions for mounting the lens 71 covering the LED 70, and the secondary battery 10, and a claw portion for mounting on the main body. (Main body attachment portion 54).

  That is, the luminaire 100 according to the first embodiment includes components (such as the lighting circuit board 30, the power supply terminal block 60, the LED 70 (an example of the light source), and the lens 71 that covers the LED 70) included in the lighting device 20 in the unit case 50. A unit case 50, which is integrally mounted by a plurality of mounting portions corresponding to each of them, and integrally mounted with components and the like constituting the lighting device 20, is mounted to the main body 40 by the main body mounting portion 54, and the lighting device 20 and the main body 40 are integrated. It is the lighting fixture 100 which can be attached to the attachment surface 200 in the state which was converted into. Furthermore, the luminaire 100 according to the first embodiment has each mounting portion that can easily attach the secondary battery 10 and the cover 80 after the main body 40 integrated with the lighting device 20 is attached to the attachment surface 200. Is also provided.

  Hereinafter, the components constituting the lighting device 20 (the lighting circuit board 30, the power terminal block 60, the LED 70 (an example of the light source), the lens 71 covering the LED 70), the secondary battery 10, and the cover 80 are provided in the unit case 50. A plurality of mounting portions for mounting will be described.

<Light source mounting part 52>
The unit case 50 has a cylindrical shape with an opening on the attachment surface 200 side, and a light source for attaching the LED 70 and the lens 71 to the substantially central portion of the case light source surface 51 that is the surface opposite to the attachment surface 200 side. A mounting portion 52 (an example of a mounting portion) is provided.

  The unit case 50 is formed with a case notch 55 that opens from the light source mounting portion 52 toward the peripheral edge of the case light source surface 51 with a predetermined width. Further, the unit case 50 has an entrance portion of the opening of the case cutout portion 55 and from the end portions 55a and 55b (see FIG. 3) of the peripheral portion of the case light source surface 51 to the end portions 55a to 55b. A side opening 535 that vertically opens the side surface of the unit case 50 is formed vertically upward (in the direction of the mounting surface 200 from the case light source surface 51) with the width of the distance. Edge portions (edge portions) on both sides of the opening of the side surface opening 535 on the side surface are substantially parallel. The side opening 535 may have a width of a distance from the end 55a to the end 55b, and may open all sides of the unit case 50 from the case light source surface 51 to the opening on the mounting surface 200 side. The planar shape of the case light source surface 51 is horseshoe-shaped, U-shaped, or U-shaped, and is substantially the same as the planar shape of the secondary battery 10 described later.

  Moreover, it opens to a predetermined position and the upper part of the side surface of the unit case 50 does not need to open. In this case, the unit case 50 has a cylindrical shape.

  Since the power supply terminal block 60 to be described later is inserted and disposed in the case cutout portion 55, the width of the case cutout portion 55 is slightly wider than the width in the longitudinal direction of the power supply terminal block 60 in consideration of workability. Thus, it is desirable to provide a gap between both edges of the case notch 55 and the power terminal block 60. However, in consideration of downsizing of the luminaire, the gap is preferably as narrow as possible.

  In addition, the unit case 50 is mounted on the main body 40 by the main body mounting portion 54 after the components constituting the lighting device 20 are integrally mounted by a plurality of mounting portions, and then the instrument mounting hole 42 of the main body 40. A case hole 501 for inserting a screwdriver or the like is provided in the case light source surface 51 so that the screw can be screwed to the mounting surface 200 through a screw. Accordingly, the case hole 501 is located at a position corresponding to the instrument mounting hole 42a and the instrument mounting hole 42b (the vertical axis of the instrument mounting holes 42a and 42b and the case light source surface 51 between the unit mounting case 50 and the main body 40). At the intersection).

  The LED 70 is installed on the LED base 701 and includes an LED connection line 702 and an LED connection terminal 703 for connecting to the lighting circuit board 30. The lens 71 is a bowl-shaped lens in which an opening for arranging an LED is formed at the bottom. The lens 71 may include a reflector for reflecting the light of the LED 70 on the side surface extending from the bottom where the LED 70 is disposed to the peripheral edge (lens edge 711) of the opening opposite to the bottom.

  The light source mounting portion 52 is formed to project in a substantially central portion of the case light source surface 51 in a cylindrical shape, and the surface on the opposite side to the case light source surface 51 side is opened to insert the LED 70. Therefore, it is preferable that the inner diameter of the light source mounting portion 52 is slightly larger than the diameter of the LED base 701 in consideration of workability. On the peripheral edge of the opening of the light source mounting portion 52, at least two claw portions 521 protruding inward are provided (see FIG. 3). Further, a slit portion 522 that vertically opens the side surface of the light source attachment portion 52 is provided on the side of the case cutout portion 55 on the side surface of the light source attachment portion 52 (see FIG. 3).

  When the LED 70 is attached to the light source attachment portion 52 (that is, attached to the unit case 50), first, the LED base 701 on which the LED 70 is installed is inserted from the opening of the cylindrical light source attachment portion 52, and the LED connection line 702 is connected. The LED connection terminal 703 at the end of the LED connection line 702 is connected to the lighting circuit board 30 described later through the case notch 55 through the slit portion 522 and pulled out to the outside of the light source mounting portion 52. As shown in FIG. 4, the lens 71 is inserted into the opening of the light source mounting portion 52 from the bottom of the lens 71 so that the LED 70 is disposed at the bottom of the lens 71, and presses the LED base 701 at the bottom of the lens 71. The lens 71 is locked inside the light source mounting portion 52 by pushing the lens edge portion 711 into contact with the claw portion 521 of the light source mounting portion 52.

<Battery accommodating portion 53>
The unit case 50 includes a battery housing portion 53 (an example of a mounting portion) that houses one side of the secondary battery 10 in contact with the case light source surface 51. The battery accommodating portion 53 will be described in detail with reference to FIGS.

  The battery housing part 53 supports a side wall part 532 that covers a part of the side surface (side wall 12) around the secondary battery 10 when the secondary battery 10 is housed, and a part of the peripheral edge part of the lower surface of the secondary battery 10. And a battery locking portion 531 for locking. The side wall portion 532 is formed by extending a part of the side surface of the unit case 50 in the case light source surface direction. The lower end portion of the side wall portion 532 is bent at a substantially right angle at the lower end portion of the side wall portion 532, and the peripheral portion of the lower surface of the secondary battery 10 is placed and supported on the bent inner surface to support the secondary battery 10. A battery locking portion 531 to be locked is formed. The battery housing portion 53 is a peripheral portion of the unit case 50, and from end portions 55 a and 55 b on both sides of the case cutout portion 55 (end portions on both sides of the entrance of the opening of the case cutout portion 55). It is formed substantially symmetrically on both sides along the peripheral edge. Side wall terminal portions (532 a, 532 b) of the side wall portions 532 of the battery housing portions 53 on both sides are positioned so that the line connecting 532 a and 532 b is divided into approximately two equal parts of the case light source surface 51. It becomes the mouth 534.

  Here, the shape of the secondary battery 10 will be described. The secondary battery 10 has a flat plate shape, and has a horseshoe shape (U-shape or U-shape) in which a battery opening portion 11 having a predetermined width is formed on one side. For example, it is a shape lacking a part of a donut shape (annular shape). Assuming that the entire surface of the battery opening 11 of the secondary battery 10 is closed, the shape of the secondary battery 10 is a donut shape, a circular shape, a ring shape, and an annular shape, and the outer shape is substantially the same as the case light source surface 51. It is preferable that it is the shape of this. Therefore, it can be said that the shape of the secondary battery 10 is substantially the same shape as that of the case light source surface 51 and the battery opening 11 having an opening with a predetermined width is formed on one side.

  The battery opening 11 forms a central opening 13 (a terminal portion of the battery opening 11) that opens at a predetermined diameter at a substantially central portion of the secondary battery 10, and is connected to the central opening 13 on one side. Are opened with a predetermined width. When the secondary battery 10 is accommodated in the battery accommodating portion 53, the light source attachment portion 52 is accommodated in the central opening portion 13. Therefore, the diameter of the central opening portion 13 is the diameter of the light source attachment portion 52 in consideration of workability. A slightly larger size is desirable. Further, when the secondary battery 10 is accommodated in the battery accommodating portion 53, the battery opening 11 and the case cutout portion 55 of the unit case 50 are substantially overlapped to form an opening. The power terminal block 60 is inserted and arranged. Therefore, it is preferable that the width of the battery opening 11 is substantially the same as the width of the case notch. Similarly to the width of the case notch 55 described above, the width of the battery opening 11 is slightly wider than the width in the longitudinal direction of the power terminal block 60 in consideration of workability because the power terminal block 60 is inserted. Thus, it is desirable to provide a gap between the both edges of the battery opening 11 and the power terminal block 60. However, considering the compactness of the lighting fixture, it is preferable that the gap is as short as possible.

  When the secondary battery 10 is accommodated in the battery accommodating portion 53 (that is, attached to the unit case 50), one side of the secondary battery 10 is placed while the light source attachment portion 52 is fitted in the battery opening 11 of the secondary battery 10. The secondary battery 10 is inserted from the battery insertion portion 534 and slid in the direction of the case cutout portion 55 while being in contact with the case light source surface 51. The secondary battery 10 is slid and accommodated until the light source mounting portion 52 is positioned at the central opening 13 (the terminal end 12 of the battery opening 11).

  At this time, the height M of the secondary battery 10 and the height N of the light source mounting portion 52 are substantially equal (M≈N). Moreover, it is preferable that the height L of the side wall portion 532 of the battery housing portion 53 is substantially equal to the height M of the secondary battery. However, in consideration of workability, the length L of the side wall portion 532 is set to the height of the secondary battery. It is preferable that there is a clearance (gap) between the surface of the secondary battery 10 that is slightly longer than the length M and is in contact with the case light source surface 51 (L ≧ M). However, in consideration of a reduction in the height H of the lighting fixture, it is preferable to make the clearance between the case light source surface 51 and the surface of the secondary battery 10 in contact as small as possible (LM = 0).

<Board mounting portion 58>
The lighting circuit board 30 is a board for controlling lighting of the LED 70 by the power of the secondary battery 10 as described above. In the present embodiment, the lighting circuit board 30 has substantially the same shape (horse-shoe shape, U shape, U shape) as the secondary battery 10, and the substrate corresponding to the battery opening 11 is similarly formed on the substrate. An opening 33 is provided. The lighting circuit board 30 may not be substantially the same shape as the secondary battery 10 and may be rectangular.

  In addition, the lighting circuit board 30 includes a plurality of mounting portions corresponding to components (such as the lighting circuit board 30, the power terminal block 60, the LED 70 (an example of a light source), and the lens 71 that covers the LED 70) constituting the lighting device 20, respectively. In order to insert a screwdriver or the like so that the main body 40 can be screwed through the instrument mounting hole 42 of the main body 40 and can be screwed to the mounting surface 200 in a state where the main body 40 is mounted integrally with the main body 40 and attached to the main body 40. The substrate hole 32 is provided. The positions of the board holes 32 are the positions corresponding to the instrument mounting holes 42a and the instrument mounting holes 42b in a state in which the unit case 50 with the lighting circuit board 30 mounted is attached to the main body 40, similarly to the position of the case holes 501 ( It is provided at a position where the vertical axis of the fixture mounting holes 42a and 42b intersects the lighting circuit board 30). That is, the operator works by inserting a screwdriver or the like from the case hole 501 of the unit case 50, passing through the board hole 32, and reaching the instrument mounting hole 42 of the main body 40. be able to.

Further, as shown in FIGS. 7A to 7C, the board claw portion 58a has a claw shape (a cross section is substantially a right triangle) at a position above the board locking base 58b on the inner side surface of the unit case 50. Protrusively provided. When the unit case 50 is viewed from above (see FIG. 7B), the positional relationship in the circumferential direction (EF direction) between the substrate claw portion 58a and the substrate locking base 58b is predetermined in consideration of workability. It is preferable that the positional relationship is shifted by a distance (distance K in FIG. 7B).

  As shown in FIG. 7A, the gap I between the upper surface 581 of the substrate locking base 58b and the bottom surface portion 583 of the substrate claw portion 58a becomes a substrate fitting portion 59 for fitting the lighting circuit substrate 30.

At this time, as shown in FIG. 5, if the substrate groove portion 31 is provided in a portion corresponding to the substrate claw portion 58 a of the side wall portion of the lighting circuit substrate 30, the lighting circuit substrate 30 can be easily fitted into the substrate mounting portion 58. Further, by providing the substrate groove 31, it can be used for positioning when the lighting circuit substrate 30 is mounted. However, the depth distance (length) of the substrate groove portion 31 needs to be shorter than the protruding length of the bottom surface portion 583 of the substrate claw portion 58a (the distance protruding from the side surface of the unit case 50). The substrate groove 31 may not be provided.

  Below, the other example of the board | substrate mounting part 58 is demonstrated. For example, a claw for attaching to the unit case 50 is provided on at least two places on the side wall surface of the lighting circuit board 30. The board mounting portion 58 is, for example, a groove provided on the inner side surface of the unit case 50, the lighting circuit board 30 is substantially parallel to the case light source surface 51, and the board opening 33 is the case notch 55 and the battery.
