FIG. 2 is a front view of the main part showing a state in which the display unit is removed from the display device same as above. FIG. 3 is a perspective view showing a main part of the outer box and two wiring members in the display device same as above.

  Hereinafter, a display device 1 according to an embodiment will be described with reference to the drawings. In the following, unless otherwise specified, the top, bottom, left, and right of the display device 1 are defined in the directions indicated by the arrows in FIG. 2, and the front side of the paper surface in FIG. That is, in a direction in which a first side wall 81 and a third side wall 83 (see FIG. 1), which will be described later, face each other, the first side wall 81 side is the top and the third side wall 83 side is the bottom. Moreover, let the longitudinal direction of the light source unit 2 mentioned later be the left-right direction. Further, a direction in which the first side wall 81 protrudes from a base portion 80 of the outer box 8 described later is a front-rear direction, a front end side of the first side wall 81 is front, and a base portion 80 side is rear.

  As shown in FIG. 1, the display device 1 of the present embodiment includes a light source unit 2, a power storage unit 3, a power supply block 4, two wiring members 5 and 6, a housing 7, and two lamp connectors 9. And a display unit 10. The display device 1 is used as a guide light, for example. The display device 1 is fixed to the ceiling surface or wall surface by screwing in a state where the outer surface of the housing 7 is in contact with the ceiling surface or wall surface. The power storage unit 3, the power supply block 4, and the two lamp connectors 9 are accommodated in the housing 7. The display device 1 is not limited to a guide light.

  The light source unit 2 includes a holder cover 21, a light source holder 22, two substrates 23, two light emitting diodes 24 (light sources), two light guide members (not shown), and a light leakage prevention member 25. .

  The light source holder 22 has a holder main body 221 and two end members 222. The holder body 221 is made of a material having a high light reflectance such as an aluminum material. The holder main body 221 is long in the left-right direction, and the left and right surfaces and the lower surface are open. The holder main body 221 is formed in a rectangular parallelepiped shape whose upper surface is recessed toward the center in the left-right direction. The two end members 222 are formed of an electrically insulating material such as a synthetic resin. The two end members 222 are attached to both ends of the holder body 221 in the longitudinal direction. The light leakage preventing member 25 is formed in a plate shape elongated in the left-right direction. The light leakage prevention member 25 closes the opening on the lower surface of the holder main body 221. The two light guide members are housed inside the light source holder 22.

  The holder cover 21 is made of an electrically insulating material such as synthetic resin. The holder cover 21 is long in the left-right direction.

Each substrate 23 is attached between the corresponding end member 222 and the holder main body 221. The two substrates 23 correspond to the two light guide members on a one-to-one basis. A light emitting diode 24 and a connection terminal (not shown) electrically connected to the light emitting diode 24 are mounted on each substrate 23.

  The light emitted from the light emitting diodes 24 on each substrate 23 enters the light guide member corresponding to the substrate 23, undergoes refraction at the light guide member and reflection at the inner surface of the holder body 221, thereby preventing the light leakage prevention member. The light leakage preventing member 25 is incident from the upper surface of 25. The light leakage prevention member 25 distributes the light incident on the light leakage prevention member 25 so that it exits from the lower light emission surface 251 and enters a later-described incident surface 105 of the display unit 10. In addition, a light diffusion film (not shown) is attached to the surface (upper surface) of the light leakage prevention member 25 on the light guide member side. As the light is diffused by the light diffusing film, the surface brightness in the left-right direction of the display panel 101 described later becomes substantially uniform in the display unit 10.

The terminal block 43 is provided with a terminal (not shown). A power line 400 (see FIG. 2) for supplying power from an external power source (not shown) such as a commercial power source is electrically connected to the terminals of the terminal block 43. The lighting circuit for normal time controls the power supplied from the external power supply via the terminal of the terminal block 43 and supplies the light emitting diode 24 of the light source unit 2 by the wiring members 5 and 6 to light the light emitting diode 24. . Control of the power supplied from the external power supply performed by the lighting circuit for normal time is, for example, converting AC power to DC power by an AC / DC converter and converting it to a desired DC voltage by a DC / DC converter. It is to be. The emergency lighting circuit lights the light emitting diode 24 with the power supplied from the storage battery of the power storage unit 3 when power is not supplied from the external power source. The charging circuit charges the storage battery of the power storage unit 3 with power supplied from an external power source.

  As shown in FIG. 1, the housing 7 has an outer box 8 (insulating portion) and a holding member 71. The housing | casing 7 and the outer case 8 are formed in the rectangular parallelepiped shape which the front surface opened.

  The outer box 8 is made of an electrically insulating material such as a synthetic resin, and has an electrically insulating property. The outer box 8 includes a base portion 80, a first side wall 81, a second side wall 82, a third side wall 83, and a fourth side wall 84 each having a plate shape.

A third side wall 83 projects forward from the lower side of the base portion 80. A fourth side wall 84 projects forward from the right side of the base portion 80.

  The holding member 71 is made of, for example, a metal plate. The holding member 71 has a main plate 711 and four positioning plates 712 (only two are shown in FIG. 1). The main plate 711 is formed in a rectangular shape. The thickness direction of the main plate 711 is the front-rear direction. The main plate 711 has a hole 713 near the center. The four positioning plates 712 are respectively provided on the four sides of the main plate 711 and protrude forward from the main plate 711. The positioning plate 712 protruding from the upper side of the main plate 711 has a hooking hole 714. As shown in FIGS. 1 and 2, the two positioning plates 712 projecting from the right side and the left side of the main plate 711 each have a hooking hole 715.

  The holding member 71 is accommodated in the outer box 8. More specifically, the main plate 711 of the holding member 71 and the base portion 80 of the outer box 8 are laminated in each thickness direction (front-rear direction). Further, the four positioning plates 712 of the holding member 71 are in contact with the inner surface of the outer box 8 at the first side wall 81, the second side wall 82, the third side wall 83, or the fourth side wall 84.

  Two hooking pieces 85 protrude from the first side wall 81 toward the inside of the outer box 8. From the 2nd side wall 82 and the 4th side wall 84, the hook piece 85 protrudes toward the inside of the outer case 8, respectively. Each holding piece 85 is inserted into the hooking hole 714 or the hooking hole 715 of the holding member 71, so that the holding member 71 is positioned inside the outer box 8.

  The outer box 8 has a plurality of holding pieces 86 (only two are shown in FIG. 1). Each holding piece 86 protrudes forward from the vicinity of the periphery of the base portion 80 and is formed in a bowl shape. The holding member 71 has a plurality of protruding pieces 716 (only two are shown in FIG. 1) protruding forward from the main plate 711. The holding member 71 is positioned inside the outer box 8 by the plurality of holding pieces 86 being hooked on the plurality of protruding pieces 716.

  The first side wall 81 has two cover hooks 87. The two cover hooks 87 penetrate the first side wall 81 in the vertical direction. The two cover hooks 87 are formed near both ends of the first side wall 81 in the left-right direction.

  Further, two panel hooks 88 project from the second side wall 82 and the fourth side wall 84 toward the internal space of the housing 7 from the vicinity of the front end. Each panel hook portion 88 includes an L-shaped portion when viewed from the left-right direction.

  As shown in FIG. 1, the housing 7 includes two first through holes 72 (through holes) penetrating the housing 7. Each first through hole 72 faces the hooking hole 714 and is formed so as to penetrate the first side wall 81. The housing 7 includes three second through holes 73 that pass through the housing 7. Each second through hole 73 faces the hole 713 and is formed so as to penetrate the base portion 80. A power line 400 (see FIG. 2) for supplying power from an external power source enters the internal space of the housing 7 from the outside of the housing 7 through the first through hole 72 or the second through hole 73, The terminal block 43 is connected to the terminal.

  The power supply block 4 is disposed at the lower right corner in the internal space of the housing 7. The power storage unit 3 is disposed adjacent to the power supply block 4 in the vicinity of the lower end of the internal space of the housing 7. That is, the power storage unit 3 and the power supply block 4 are disposed adjacent to the third side wall 83. The storage battery storage unit 31, the base unit 42, and the terminal block 43 of the power storage unit 3 are attached to the holding member 71 by screws.

  The two lamp connectors 9 are disposed in the upper right corner and the upper left corner in the internal space of the housing 7. That is, the two lamp connectors 9 are arranged near both ends in the longitudinal direction (left-right direction) of the first side wall 81. Each lamp connector 9 is electrically connected to the light emitting diode 24. More specifically, the two lamp connectors 9 correspond one-to-one to the two substrates 23 of the light source unit 2, and are connected to the light emitting diodes 24 mounted on the corresponding substrates 23 via connection terminals on the substrate 23. Are electrically connected.

  As shown in FIGS. 1 and 2, the light source unit 2 is disposed in the vicinity of the first side wall 81. More specifically, the light source holder 22 of the light source unit 2 is attached to the housing 7 while being accommodated in the internal space of the housing 7 along the first side wall 81. Since the light emitting diodes 24 are provided near both ends in the longitudinal direction (left-right direction) of the light source holder 22, the light emitting diodes 24 are located in the vicinity of the lamp connector 9. The holder cover 21 is attached to the light source holder 22 and covers the front surface of the housing 7 together with the display unit 10. The holder cover 21 has two hooking claws (not shown) on the upper side. The two hooking claws are hooked to the two cover hooking portions 87 provided on the first side wall 81 in a one-to-one correspondence.

  The first through hole 72 is provided at a position closer to the light source holder 22 of the light source unit 2 than to the power supply block 4.

  As shown in FIGS. 2 and 3, the second piece 52 of the wiring member 5 and the second piece 62 of the wiring member 6 are embedded in the base portion 80. More specifically, the second piece 52 and the second piece 62 are formed integrally with the base portion 80 by simultaneous molding (for example, insert molding). Thus, since the 2nd piece 52 and the 2nd piece 62 are embedded in the electrically insulating base part 80, possibility of touching accidentally will be reduced. That is, the possibility that the second piece 52 and the second piece 62 are accidentally contacted with another member and short-circuited, or caught by an operator's hand or a tool or the like is reduced.

  The first piece 51 of the wiring member 5 protrudes from the second piece 52 embedded in the base portion 80 to a space formed by the base portion 42 and the power supply cover attached to the base portion 42. The first piece 61 of the wiring member 6 protrudes from the second piece 62 embedded in the base portion 80 to the space formed by the base portion 42 and the power supply cover. The first piece 51 and the first piece 61 are sandwiched between the blade holders (not shown) mounted on the power supply substrate 41 of the power supply block 4 by the elastic force of the blade holders. The first piece 51 and the first piece 61 are electrically connected to a normal lighting circuit and an emergency lighting circuit of the power supply block 4 using a blade support as a terminal. The main plate 711 of the holding member 71 has a through hole (not shown) through which the first pieces 51 and 61 pass, and is formed so that the holding member 71 and the wiring members 5 and 6 do not come into electrical contact.

  The third piece 53 and the fourth piece 54 of the wiring member 5 are embedded in the second side wall 82 of the housing 7. More specifically, the third piece 53 and the fourth piece 54 are formed integrally with the second side wall 82 by simultaneous molding. Thus, since the 3rd piece 53 and the 4th piece 54 are embedded in the electrically insulating 2nd side wall 82, possibility that it will short-circuit accidentally or will be disconnected is reduced. The fourth piece 54 is arranged so that the longitudinal direction thereof is along the longitudinal direction (vertical direction) of the second side wall 82.

  The third piece 63 and the fourth piece 64 of the wiring member 6 are embedded in the fourth side wall 84 of the housing 7. More specifically, the third piece 63 and the fourth piece 64 are formed integrally with the fourth side wall 84 by simultaneous molding. Thus, since the 3rd piece 63 and the 4th piece 64 are embedded in the electrically insulating 4th side wall 84, it is suppressed that it short-circuits or disconnects accidentally. The fourth piece 64 is disposed so that the longitudinal direction thereof is along the longitudinal direction (vertical direction) of the fourth side wall 84.

  As described above, since part of the wiring members 5 and 6 are embedded in the housing 7, for example, when the light source unit 2 is attached to the housing 7, wiring is performed between the light source unit 2 and the housing 7. It is suppressed that the member 5 (6) is pinched and the wiring member 5 (6) is disconnected. Alternatively, it is possible to prevent the wiring member 5 (6) from being short-circuited by being sandwiched together with the power supply line 400 passed through the internal space of the housing 7 or being disconnected by being caught by the power supply line 400. . Moreover, compared with the case where it replaces with the wiring member 5 (6) and a covered electric wire is wired in the internal space of the housing | casing 7, the effort of the wiring process which attaches a terminal to a covered electric wire or fixes a covered electric wire reduces.

  As shown in FIGS. 1 and 3, the fifth piece 55 of the wiring member 5 protrudes from the fourth piece 54 embedded in the second side wall 82 to the internal space of the housing 7. The fifth piece 65 of the wiring member 6 protrudes from the fourth piece 64 embedded in the fourth side wall 84 to the internal space of the housing 7. The fifth piece 55 and the fifth piece 65 are connected to the two lamp connectors 9 in a one-to-one correspondence.

  As described above, the wiring members 5 and 6 electrically connect the power supply block 4 and the light emitting diode 24 of the light source unit 2 through the lamp connector 9 and the connection terminals on the substrate 23.

  As described above, the power supply block 4 and the lamp connector 9 are electrically connected by the wiring members 5 and 6 without using an electric wire such as a copper wire. Further, the connection terminal on the board 23 and the lamp connector 9 are also electrically connected by a metal plate. Further, the power supply block 4 and the terminals of the terminal block 43 and the storage battery of the power storage unit 3 and the power supply block 4 are also electrically connected using a metal plate, a lead frame, or the like. Thus, in the display device 1, the electrical connection between the components is made without using an electric wire such as a copper wire. Thereby, the labor of wiring processing is reduced, and the workability in the internal space of the housing 7 is improved.

  As shown in FIG. 1, the display unit 10 is formed in a rectangular plate shape. The display unit 10 is formed by stacking a display panel 101, a diffusion plate (not shown), a light guide plate (not shown), and a reflection plate (not shown) in this order, and holding them inside the panel case 102. The display panel 101 and the light guide plate are formed of a material such as a light-transmitting synthetic resin. A pictogram 103 is attached to the display panel 101. The panel case 102 is made of an electrically insulating material such as synthetic resin. The panel case 102 is formed in a rectangular parallelepiped shape whose front and upper surfaces are open. Four protrusions 104 are provided on the rear surface of the panel case 102. Of the four protrusions 104, two protrusions 104 protrude backward from the vicinity of the left end of the rear surface of the panel case 102, and the tip protrudes further to the left. The remaining two protrusions 104 protrude rearward from the vicinity of the right end of the rear surface of the panel case 102, and the tip protrudes further to the right. The four protrusions 104 are hooked corresponding to the four panel hooking portions 88 of the outer box 8 on a one-to-one basis.

  The display unit 10 is attached to the outer box 8 together with the light source unit 2 so as to cover the front surface of the outer box 8. In the display unit 10, the incident surface 105, which is the upper surface, faces the light emitting surface 251 of the light source unit 2. The light emitted from the light emitting diode 24 is extracted from the light emitting surface 251 through the inside of the light source holder 22, enters the light guide plate from the incident surface 105 of the display unit 10, and is refracted by the light guide plate and reflected by the reflection plate. After being reflected, it is emitted toward the diffusion plate. Further, the light is diffused substantially uniformly over the entire surface of the display panel 101 by the diffusion plate. Thereby, the display panel 101 is illuminated.

  As described above, the display device 1 according to the present embodiment includes the housing 7, the power supply block 4, the light source (light emitting diode 24), and the wiring member 5 (6). The housing 7 includes an insulating portion (outer box 8). The insulating portion has electrical insulation. The power supply block 4 is accommodated in the housing 7. The light source is turned on when power is supplied from the power supply block 4. The wiring member 5 (6) electrically connects the power supply block 4 and the light source. The wiring member 5 (6) is at least partially embedded in the insulating portion.

  With the above configuration, in the display device 1, at least a part of the wiring member 5 (6) is embedded in the insulating portion (outer box 8) of the housing 7. This reduces the possibility of accidentally touching the part embedded in the insulating part of the wiring member 5 (6). Therefore, the portion embedded in the insulating portion of the wiring member 5 (6) is erroneously attached during the installation work of other wiring or other members as compared with the case where it is accommodated in the internal space of the housing 7. It is difficult to be pinched together with other wiring or to be caught by an operator's hand or tool. That is, the display device 1 has better workability in the internal space.

  Further, in the display device 1 according to the present embodiment, the wiring member 5 (6) has a strip shape.

  With the above configuration, the wiring member 5 (6) has a strip shape. Therefore, the wiring member 5 (6) can be embedded in the insulating portion (outer box 8) of the housing 7 without increasing the thickness of the housing 7 too much.

  The display device 1 according to the present embodiment further includes a light source holder 22. A light source (light emitting diode 24) is attached to the light source holder 22. The housing 7 includes a through hole (first through hole 72). The through hole is closer to the light source holder 22 than to the power supply block 4. The through hole allows the power line 400 to pass from the outside of the housing 7 to the internal space of the housing 7. The power supply line 400 supplies power to the power supply block 4.

  With the above configuration, the housing 7 includes a through hole (first through hole 72) for passing the power line 400 from the outside of the housing 7 to the internal space of the housing 7. The through hole is provided at a position closer to the light source holder 22 to which the light source (light emitting diode 24) is attached than to the power supply block 4. When the power supply line 400 is electrically connected to the power supply block 4, the portion of the power supply line 400 that passes through the internal space of the housing 7 is longer as the through hole is away from the power supply block 4. On the other hand, at least a part of the wiring member 5 (6) that electrically connects the power supply block 4 and the light source is embedded in the housing 7. As a result, the power supply line 400 and the wiring member 5 (6) are prevented from spatially interfering with each other in the internal space of the housing 7. Therefore, when the power supply line 400 is wired, the wiring member 5 (6) can be prevented from being sandwiched together with the power supply line 400 or being caught by the power supply line 400. That is, the workability of attaching the power supply line 400 is improved.

  The wiring members 5 and 6 may not be formed in a band shape. For example, the wiring members 5 and 6 may be copper wires having a circular cross section.

  Further, the display device 1 may not include the light source holder 22.

  Further, the housing 7 may not include the first through hole 72.

  Further, the light source in the light source unit 2 is not limited to the light emitting diode. For example, an organic electroluminescence element, a laser diode element, an incandescent lamp, a mercury lamp, or a fluorescent lamp may be used as the light source.

  Further, the number of the substrates 23 is not limited to two, and may be one or three or more. Further, the number of light emitting diodes 24 mounted on the substrate 23 may be one or plural.

  Moreover, the number of wiring members (wiring members 5 and 6) is not limited to two, and may be one or three or more.

  The light source may be externally attached to the housing 7.

  Further, the display device 1 may be formed so that a part of the housing 7 can be embedded in a ceiling or a wall.

  Moreover, the housing | casing 7 should just have an electrical insulation at least the part by which the wiring members 5 and 6 are embedded. The portion where the wiring members 5 and 6 are not embedded may be formed of a conductive material such as metal.

  In addition, the method of embedding at least a part of the wiring member 5 (6) in the insulating portion of the housing 7 is a method of part of the wiring member 5 (6) (second pieces 52, 62, third, etc.) as in the present embodiment. The pieces 53 and 63 or the fourth pieces 54 and 64) are not limited to a method in which the pieces are integrally formed with the insulating portion. For example, at least a part of the wiring member 5 (6) may be disposed between two insulating portions included in the housing 7 so as not to be exposed to the internal space of the housing 7. It is assumed that at least a part of the wiring member 5 (6) is embedded in the insulating portion.

  Further, in the present embodiment, the wiring members 5 and 6 are electrically connected to the power supply block 4 by the blade support provided in the power supply block 4, but the method of connecting the wiring members 5 and 6 to the power supply block 4 is also used. Is not limited to this. For example, a blade support may be provided on the wiring members 5 and 6 and connected to a plug blade provided on the power supply block 4. Further, the wiring members 5 and 6 may be connected to the power supply block 4 by terminals having other shapes.
