  The insertion opening 79 is inserted into the auxiliary heat radiating portion 42b of the auxiliary heat radiating plate 42 so that the auxiliary heat radiating portion 42b protrudes into the partition recess 87 above the lower case 73. The insertion opening 79 is formed in a longitudinal slit shape along the one side other side direction at the position of the end of the end recess 77b of the recess 77.

  The substrate support portion 80 accommodates the lower portion of the substrate portion 43, and is a portion for bringing the lower end portion of the substrate body 61 of the substrate portion 43 closer to the decorative frame 22 (FIG. 16) side, and the lower case 73 (case body 44 ( This is the lowermost part of the unit part 16)). In the substrate support portion 80, a concave portion 89 for regulating the position of one side of the light source module 41 (module main body portion 41a) is formed in an arc shape along the same arc as the restriction portion 81 on the side facing the concave portion 77. Has been. Further, a switch 63 and a monitor lamp 64 are communicated with the opening 37 of the decorative frame 22 at the lower surface of the substrate support portion 80, that is, the lowermost end of the substrate support portion 80 (case body 44 (unit portion 16)). Each circular opening 90 to be exposed is opened.

  The restriction portion 81 positions the light source module 41 with respect to the case body 44 by restricting the light source module 41 (module body portion 41a) together with the restriction recess 89 in one direction. The restricting portion 81 is formed in an arc rib shape at a position on one side of the storage recess 82.

  The storage recess 82 is a portion that stores the relay connector 19 and the like, and is provided with a recess in the lower portion. That is, the storage recess 82 is a portion whose lower part is covered with the decorative frame 22 (FIG. 16). Further, in the housing recess 82, a through hole 92 through which another wiring 91 for directly electrically connecting the terminal block 18 and the relay connector 19 is inserted is opened through the lower case 73 in the vertical direction. .

  The communication port 84 is a portion through which one wiring 71 is inserted, and is opened through the lower case 73 in the vertical direction.

  Each attachment piece 85 is a portion that holds the fixing bracket 45 and is overlapped with the lower portion of each bracket 27a in a state where the unit portion 16 is inserted into the instrument main body 15 and accommodated. A screw boss portion 85a for holding the screw 46 protrudes from the upper portion of the attachment piece portion 85. No screw is formed on the inside of these screw bosses 85a (the side through which the screw 46 is inserted), and the screw formed on each bracket 27a and the screw formed on the end of the screw 46 are locked. Thus, the unit portion 16 is fixed to the instrument body 15. That is, the screw 46 is locked to the screw boss portion 85a regardless of whether the unit portion 16 is fixed to the instrument body 15. In the drawing, in order to clarify the explanation, the screw 46 may be shown in a state where it is removed from the screw boss portion 85a.

  The partitioning recess 87 is located at a substantially central part on the upper side of the lower case 73. An exposure opening 78 and an insertion opening 79 communicate with the partition recess 87. In addition, a battery holding portion 96 that accommodates and holds the lower portion of the battery pack 17 in an inclined manner with respect to the other side direction is formed in the partition recess 87 so as to be recessed in an arc shape in cross section. . With this battery holding portion 96, one end side of the battery pack 17 is separated from the connection connector 66 (fixed side connector portion 66a) in the other direction.

  On the other hand, the upper case 74 shown in FIG. 6 has a lid shape with the lower side opened, and the inside is an upper substrate housing portion that communicates with the substrate support portion 80. That is, the upper case 74 covers the upper side of the substrate support unit 80 (substrate unit 43). At both ends of the lower end of the upper case 74, claw portions 99 for engaging the locking openings 98 respectively opened at the ends of the lower case 73 to lock the upper case 74 to the lower case 73. (Only one is shown) protrudes. Further, at the upper end portion of the upper case 74, a connector opening 101 and a connector exposure opening 102 for exposing the connection connector 66 and the power connection connector 67, respectively, are opened. The connector opening 101 is opened toward the other side and faces the partitioning recess 87 of the lower case 73. Further, the connector exposure opening 102 is opened upward.

  Each fixing bracket 45 (for example, FIG. 9) is formed by press molding or the like with a metal such as aluminum, which is a heat radiating member having excellent thermal conductivity. As a general rule, the light source module 41 is moved from below to the case body 44. A long metal fitting body 105 as a holding part to be pressed (supported), the attachment parts 106 and 106 which are bent continuously in a stepped manner at both ends in the longitudinal direction of the metal fitting body 105, and these attachment parts Contact portions 107 and 107 that are folded back and face above 106 and 106 are integrally provided. In addition, one fixing fitting 45 is formed with a wiring holding portion 108 that is located opposite to the communication port 84 and holds one wiring 71 at one end in the longitudinal direction of the fitting main body 105.

  The metal fitting body 105 is a portion that holds both ends of the light source module 41 against the case body 44 by pressing the arm portion 58b of the heat radiating portion 58 of the light source module 41 against the case body 44 (the lower surface 76 of the lower case 73). is there.

  The mounting portions 106 and 106 are portions that are respectively overlapped with lower portions of the mounting piece portions 85 and 85 of the case body 44 and screwed with screws 46, and extend from both ends in the longitudinal direction of the metal fitting body 105. The thickness of the heat radiating portion 58 is bent so as to be positioned in a stepped upward direction with respect to the metal fitting body 105.

  The contact portions 107 and 107 are portions that are respectively overlapped with the screw boss portions 85a and 85a of the upper portion of the attachment piece portions 85 and 85 of the case body 44 and locked by the screw 46, and the fitting main body of the attachment portions 106 and 106 It is folded from the end opposite to 105. Therefore, the fixing bracket 45 can be mounted by sandwiching the mounting pieces 85 and 85 of the case body 44 vertically by the mounting portions 106 and 106 and the contact portions 107 and 107.

  The wiring holding part 108 controls the position by pressing down one wiring 71 introduced from the communication port 84 into the housing recess 82 from below. The wiring holding part 108 is formed so as to be bent so as to protrude downward in a U shape with respect to the metal fitting body 105.

  Further, the battery pack 17 shown in FIGS. 4A, 4B, 8, 13 and 16, etc. has a case body 44 of the unit portion 16 with the unit portion 16 attached to the instrument body 15. The lower end side is held by the battery holding portion 96 of the partition recess 87 and is located on the other side above the light source module 41, and is charged by the electric power supplied from the external power source through the terminal block 18 when not in use. In addition, lighting power is supplied in emergency (at least when power supply to the external power supply is stopped) or during inspection. The battery pack 17 is a shrink pack in which a plurality of battery main bodies (not shown) are collected by a thin film, and does not include a dedicated case. The battery main body is a rechargeable battery such as a nickel cadmium battery, a nickel hydride battery, or a lithium ion battery, and is electrically connected to each other in series. In the present embodiment, a battery pack 17 having a relatively large capacity is used. For example, a plurality of battery main bodies such as single 2 type are used.

  The terminal block 18 shown in FIG. 15 (b), FIG. 16 and FIG. 17 is supplied with power for lighting the LED 55 (FIG. 2) or power for charging the battery pack 17 from an external power source. 15 (lighting fixture 11) is electrically connected to an external power source via a cable 111 that is a power supply line, and inside the fixture body 15, the lighting circuit 68 and charging of the board unit 43 are connected via a relay connector 19. The circuit 69 is electrically connected. The terminal block 18 includes a pair of connection portions 112 and 112, and is attached to the mounting bracket 113 so that the connection portions 112 and 112 are arranged vertically. The mounting bracket 113 is made of, for example, metal, and is fixed to the terminal block recess 28 of the case body 44 by screws (not shown). Therefore, the terminal block 18 is located in the vicinity of the upper end portion on the other side with respect to the light source module 41 in the instrument main body 15, and is disposed to face the inclined portion 30. Further, the cable 111 is inserted and connected to the connecting portions 112 and 112 in a substantially horizontal direction along the tangential direction of the instrument main body 15 (main body portion 21) from the side.

  The relay connector 19 shown in FIGS. 2 and 9 is formed in a longitudinal shape, and is housed and held together with a part of one wiring 71 and another wiring 91 from below in the housing recess 82. ing. This relay connector 19 is a unit side that is one connector part that is electrically connected to the lighting circuit 68 and the charging circuit 69 (on the unit part 16 side) of the board part 43 through the power connection connector 67 and one wiring 71. A connector 19a, and a terminal block side connector 19b, which is another connector portion that is electrically connected to the terminal block 18 via another wiring 91 and is attached to and detached from the unit side connector 19a, are provided.

  And the assembly of the lighting fixture 11 is demonstrated with reference to FIG. 1 thru | or FIG. First, on the instrument body 15 side, the terminal block 18 is attached to the terminal block recess 28 of the instrument body 15 (main body portion 21) via the mounting bracket 113, and another wiring 91 is connected to the terminal block 18. .

  Further, on the unit part 16 side, the light source module 41 is assembled, and the substrate part 43 is accommodated in the case body 44. The light source module 41, the auxiliary heat sink 42, the fixing brackets 45, 45 and the case body 44 Each screw 46 is attached.

  That is, in the light source module 41, the light source substrate 51 on which the LED 55 and the connector 56 are mounted is thermally connected to the lower portion of the heat radiating portion main body 58a of the heat radiating portion 58, and the cover portion 59 that holds the lens 53 with respect to the heat radiating portion 58. Assembling is carried out by covering from below and fixing with case fixing members 60, 60 (FIG. 3). Further, an upper case 74 is placed from above the lower case 73 that holds the lower end portion of the substrate portion 43 on the substrate support portion 80, and the lower case 73 and the upper case 74 are locked and fixed to the inside of the case body 44. The part 43 is accommodated (FIG. 6).

  Then, in the lower part of the case body 44, the auxiliary heat sink 42 is fitted into the recess 77 while the auxiliary heat sink 42b is inserted into the insertion opening 79 of the case body 44, and the light source module 41 is fitted to the auxiliary heat sink 42. On the other hand, it is fitted between the restricting portion 81 and the restricting recess 89 so as to overlap (FIG. 7).

  Furthermore, fixing brackets 45 are attached to the case body 44 from both ends of the case body 44 (FIG. 9). At this time, in each fixing bracket 45, the bracket body 105 holds the arm portion 58b of the heat radiating portion 58 of the light source module 41, and the mounting portion 106 and the contact portion 107 sandwich the mounting piece portions 85 of the case body 44 vertically. The two ends of the case body 44 are temporarily fixed along the other side. As a result, the heat radiating portion 58 of the light source module 41 is pressed against the auxiliary heat radiating plate 42 and thermally connected to each other.

  In this state, the screws 46 and the fixing brackets 45, 45 are integrally held with respect to the case body 44 by inserting the screws 46 into the fixing brackets 45, 45 and holding the screws 46 on the screw bosses 85a. The unit part 16 is assembled.

  Furthermore, attachment of the lighting fixture 11 to the embedding hole 12 will be described. In the instrument main body 15, another wiring 91 connected to the terminal block 18 is connected, and the other wiring 91 and the terminal block side connector 19b connected to the other wiring 91 are connected to the instrument main body 15 from the communication opening 28a. Insert it inside. In this state, the instrument body 15 in which the cable 111 led out from the embedded hole 12 is inserted and connected along the tangential direction of the instrument body 15 (main body part 21) from the side to the connection parts 112 and 112 of the terminal block 18, respectively. The upper end of the terminal block 18 side is inserted into the embedded hole 12 first, in other words, the instrument body 15 is inclined obliquely with respect to the embedded hole 12 so that the inclined portion 30 side is the lower side. Insert from below and mount (Figure 1). At this time, the instrument body 15 elastically deforms and holds the mounting springs 23 using the escape portions 29 and 29 so as to follow the side surfaces of the instrument body 15 (main body part 21), and on the inclined part 30 side. A certain one side is inserted into the embedding hole 12 from below with an appropriate inclination so as to be positioned relatively below the other side. Thereafter, by using the inclination of the inclined portion 30, the instrument body 15 is rotated in the vertical direction so that the central axis L1 is along, thereby facilitating attachment to the embedding hole 12. When the hooking portion 23b of each attachment spring 23 moves upward from the embedding hole, the holding of each attachment spring 23 is released. As a result, each mounting spring 23 expands to the side of the fixture body 15 by a repulsive force against elastic deformation, abuts against the upper edge of the embedding hole 12 and lifts the lighting fixture 11 upward. The upper surface of the main body 33 comes into contact with the ceiling surface, and the installation of the instrument main body 15 (main body portion 21) is completed.

  Next, the battery pack 17 and the unit part 16 are inserted and attached to the instrument body 15. Specifically, at the upper part of the case body 44 of the unit portion 16, the lower end portion of the battery pack 17 is fitted to the battery holding portion 96 of the partition recess 87, and the connection electrically connected to the battery pack 17 The connection-side connector portion 66b of the connector 66 is connected to the fixed-side connector portion 66a of the substrate portion 43 exposed from the connector opening 101.

  Further, the other wiring 91 and the terminal block side connector 19b located inside the instrument main body 15 (FIG. 16) are inserted into the through hole 92 from above, and the one wiring 71 and the unit side connector 19a are connected to the communication port 84. The unit side connector 19a and the terminal block side connector 19b are connected with the connector 19a and 19b (relay connector 19) together with the wires 71 and 91 stored in the storage recess 82. Meanwhile, the unit portion 16 holding the battery pack 17 is inserted from the lower end side of the instrument body 15 (FIG. 10). At this time, the attachment pieces 85 of the case body 44 of the unit part 16 and the contact portions 107 of the fixing brackets 45 sandwiching the attachment pieces 85 are overlapped with the bracket 27a of the instrument body 15 from below.

  And the unit part 16 is fixed to the instrument main body 15 with the fixtures 45 and 45 using the screw 46 hold | maintained at the screw boss | hub part 85a (FIG. 2 and FIG. 11). As a result, each contact portion 107 (FIG. 9) of the fixture 45 is pressed against the bracket 27 a of the fixture body 15, and the heat radiating portion 58 of the light source module 41 passes through the fixture 45 via the fixture 45. The thermal connection with the auxiliary heat sink 42 is further strengthened.

  Thereafter, the decorative frame 22 is inserted from the lower end portion of the main body portion 21, and the locking springs 34, 34 are locked to the locking openings 26, 26 from the inside of the main body portion 21 to thereby fix the decorative frame 22 to the main body portion. 21, the lens 53 of the light source module 41 protrudes from the exit opening 36, and the switch 63 and the monitor lamp 64 are exposed from each opening 37, and the unit part 16, the battery pack 17 and the relay connector 19 are exposed in the instrument body 15. The mounting of the luminaire 11 containing the light into the embedding hole 12 is completed.

  In the luminaire 11, the central portion of the light source module 41 (the optical axis of the LED 55) coincides with the central axis L 1 of the luminaire main body 15 in the luminaire main body 15. And the battery pack 17 and the terminal block 18 are arranged on the other side and above the light source module 41.

  When the lighting circuit 68 of the substrate unit 43 has a constant lighting circuit, the lighting fixture 11 to which an external power source is supplied from the terminal block 18 supplies a constant current to the LED 55 from the constant lighting circuit. The charging circuit 69 charges the battery pack 17 as necessary. In an emergency such as a power failure, the emergency lighting circuit of the lighting circuit 68 to which power is supplied from the battery pack 17 turns on the LED 55 in an emergency. That is, when the lighting circuit 68 has a constant lighting circuit, the constant lighting circuit of the lighting circuit 68 is switched to the emergency lighting circuit.

  The heat generated by the lighting of the LED 55 is transmitted from the heat radiating portion 58 to the instrument main body 15 via each fixing bracket 45 and also to the auxiliary heat radiating plate 42. As a result, in addition to the heat radiation by the heat radiating portion 58 itself, heat is radiated by the instrument body 15, and in the auxiliary heat radiating plate 42, heat is transmitted to the auxiliary heat radiating portion 42b located in the space portion to be radiated, and the LED 55 The heat from is surely radiated.

  Further, during the maintenance of the lighting fixture 11 attached to the ceiling surface, the unit portion 16 and the battery pack 17 are sequentially removed from the fixture main body 15 in the reverse order of the attachment. That is, first, the locking springs 34, 34 of the decorative frame 22 are removed from the locking openings 26, 26, and the decorative frame 22 is removed from the main body 21 (FIG. 2). In the unit part 16 exposed in this state, the unit side connector 19a and the terminal block side connector 19b of the relay connector 19 are removed from each other, and the screw 46 of the unit part 16 is rotated to remove the unit part 16 from the instrument body 15. Thus, as shown in FIG. 10, the battery pack 17 is integrally pulled out from the instrument body 15 and removed. When the battery pack 17 needs to be replaced, the battery pack 17 is replaced after the connection with the connection connector 66 is removed. The light source module 41 and the substrate unit 43 are replaced by opening the case body 44 or replacing the case body 44 together.

  The effects of the first embodiment will be described below.

  As described above, in the first embodiment, the heat radiation part 58 of the light source module 41 and the instrument main body 15 are thermally connected to each other by the fixing brackets 45 and 45 that fix the unit part 16 to the instrument main body 15. The heat generated by the LED 55 of the light source module 41 is transmitted from the heat radiating portion 58 to the fixture body 15 via the fixing brackets 45 and 45. Therefore, by effectively using the structures of the fixing brackets 45 and 45 and the lighting fixture 11, the fixture main body 15 can be used for heat dissipation in addition to the heat radiating portion 58 of the light source module 41. The heat capacity can be increased without unnecessarily increasing the heat dissipating portion 58 to be arranged and without using a special member, so the lighting fixture 11 can be reduced in size, that is, the lighting fixture 11 can be downsized. However, the light source module 41 with higher output can be supported.

  In addition, by fixing the unit part 16 to the instrument body 15 and providing the wiring holding part 108 for holding the one wiring 71 in the fixing bracket 45, the fixing bracket 45 can be used effectively to make the periphery of the relay connector 19 compact. The structure put together can be realized.

  Furthermore, the heat capacity can be further increased by providing the unit part 16 with the auxiliary heat radiation plate 42 that is thermally connected to the heat radiation part 58 of the light source module 41 and radiates the heat of the LED 55 to the external space part. The light source module 41 with higher output can be supported.

  In addition, the lighting fixture 11 has a configuration in which the lens 53 protrudes outside from the exit opening 36 of the decorative plate 22 in order to respond to installation conditions such as the height of the ceiling and the required light distribution characteristics by variations of the lens 53. Therefore, it is not necessary to change the height of the instrument body 15 depending on the variation of the lens 53, and it is also necessary to design the lens 53 so as to allow for the maximum dimensions (the height H1 and the radial dimension D2 in FIG. 14). In addition, the height of the instrument body 15 can be set according to the dimension of only the portion located above the decorative frame 22, that is, in the instrument body 15. Therefore, for example, compared with a configuration in which light distribution control means such as a reflector is embedded in the instrument body as in a conventional lighting instrument using a mini-halogen lamp as a light source, the instrument body 15 does not depend on the light distribution control means. The height, that is, the height of the luminaire 11 can be reduced, and the luminaire 11 can be reduced in size (reduced height).

  In addition, since the inclined portion 30 and the terminal block 18 are arranged on the upper end side of the instrument main body 15 so as to face the inclined portion 30, the instrument main body 15 can be easily attached to the embedded hole 12. Specifically, with the terminal block 18 connected to an external power source via the cable 111, the inclined portion 30 tilts one side opposite to the terminal block 18 side of the instrument body 15 to the lower side opposite to the insertion direction. The device body 15 can be attached to the embedded hole 12 by inserting it obliquely and rotating in the embedded hole 12 using the inclined portion 30, so that there is a clearance between the embedded hole 12 and the device body 15. This makes it easy to secure the instrument body 15 in the embedded hole 12. That is, since the terminal block 18 is disposed on the side of the instrument body 15 in consideration of adhesion of dust and the like, in the state where the cable 111 is connected to the terminal block 18, the position on the terminal block 18 side is the cable 111. Therefore, the instrument main body 15 tends to be inclined when inserted into the embedding hole 12. Therefore, by providing the instrument body 15 with the inclined portion 30 on the side opposite to the terminal block 18, it can be inserted into the embedding hole 12 in such an inclined state. Can be improved.

  Furthermore, by arranging the battery pack 17 on the other side with respect to the light source module 41 in the instrument body 15, that is, on the opposite side to the inclined part 30 whose height is lowered by the inclined part 30 of the instrument body 15, A storage space for the battery pack 17 can be secured. In particular, when a light source module 41 having a high output is used, the battery pack 17 is also relatively large, so by disposing the battery pack 17 in the instrument body 15 avoiding the inclined portion 30 side, The height does not have to be higher than necessary, and the lighting fixture 11 does not become larger than necessary.

  In the first embodiment, the light source module 41 is at least partly higher than the one component 62 with respect to the light source module 41 having an arc shape on the outer edge of the module main body 41a, for example, a circular shape in the present embodiment. The substrate main body 61 of the substrate portion 43 is arranged with the switch 63 and the monitor lamp 64 along the outer edge of the light source module 41 on the other main surface 61b side of the substrate main body 61 on which the switch 63 and the monitor lamp 64 are mounted. That is, from the center of the module main body 41a to the other main surface 61b between the other main surface 61b of the planar substrate main body 61 and the module main body 41a of the light source module 41 of the outer edge curved in a circular shape. The farther away from the position where the virtual normal of the crossing and the other main surface 61b cross, the more the dead space will be created, so in this dead space the switch is higher than the one part 62 Since 63 can be disposed and the switch 63 and the monitor lamp 64 can be disposed along the outer edge of the light source module 41, the mounting efficiency can be improved.

  In addition, since the switch 63 and the monitor lamp 64 are mounted on the board body 61 of the board 43 constituting the lighting circuit 68, there is no need to provide a separate board dedicated to the switch 63 or the monitor lamp 64, and the size of the board 43 Can be increased (maximized) within the instrument body 15. In addition, a monitor lamp 64 having a height lower than that of the switch 63 is mounted on the other main surface 61b of the substrate body 61 at a position relatively close to the module body 41a of the light source module 41. The mounting space for the lamp 64 can be secured, and the position of the monitor lamp 64 is closer to the center of the light source module 41, that is, the center of the luminaire 11 when viewed from below, so that the visibility is improved.

  In the first embodiment, for example, as a relatively low ceiling (for example, 2.1 to 5.0 m), that is, as a lighting device 11 for a low ceiling, for example, the light output of the light source module 41 is relatively small, for example, 13 W. For example, since the capacity of the battery pack 17 may be relatively small, the battery pack 17 using an AA type battery main body can be obtained. In this case, for example, as in the second embodiment shown in FIG. 18, the height of the instrument body 15 can be further suppressed (for example, about 79 mm), and further downsizing (low profile) can be achieved. Is possible. For example, as shown in FIG. 14, the overall height of the lens 53 is H1, the protruding height from the exit aperture 36 is H2, the radius dimension of the portion projecting from the exit aperture 36 is D1, and the overall radius dimension is D2. In the case of a relatively low ceiling (for example, 2.1 to 5.0 m), that is, a lighting device 11 for a low ceiling, the height H1 is 13.5 mm, the protruding height H2 is 8.8 mm, and the radial dimension D2 Is 34.2 mm, and the radial dimension D2 is 46 mm. The ratio of the height H1 of the entire lens 53 to the height of the instrument body 15 is 17.0% (about 20%). Furthermore, the ratio of the protrusion height H2 of the lens 53 to the height of the instrument body 15 is 11.1% (about 10%). That is, the height of the instrument body 15 is 5.9 times (approximately 6 times) the height H1 of the entire lens 53, and 9.0 times the protrusion height H2 of the lens 53.

  In each of the above embodiments, if the heat from the LED 55 can be reliably radiated by the heat radiating portion 58 and the instrument main body 15, the auxiliary heat radiating plate 42 may be unnecessary. That is, the auxiliary heat sink 42 is not an essential configuration.

  Furthermore, although the instrument body 15 is entirely formed of a heat radiating member, if the heat from the LED 55 can be reliably radiated, a part including the part (bracket 27a) thermally connected to the heat radiating part 58 by the fixing bracket 45 It is also possible to form only by a heat radiating member.

  In addition to the LED 55, for example, a light emitting element such as a laser diode or an organic EL element (OLED) can be used as the light emitting element.

  Further, if the lighting circuit 68 has at least an emergency lighting circuit, the constant lighting circuit is not an essential configuration. That is, the luminaire 11 may be turned on only in an emergency.

  The lens 53 may be made of glass or resin, and when the lens 53 is made of resin, a glass cover is provided on the light emission direction side of the lens 53. It is done.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
