Description

[Technical field]

[0001] An embodiment of the present invention relates to a lighting device including a battery. [Background technology]

[0002] Conventionally, in a lighting device equipped with an emergency lighting unit, a battery that supplies power to the emergency lighting unit is disposed in a recess in the fixture body. The fixture body has a top surface portion that is attached to the ceiling and side surfaces on both sides, which form a recess that is open on the bottom side. The battery is disposed in the recess in the fixture body and is attached to the top surface portion.

[0003] There is a demand for such lighting devices to be compact, but because the width of the recess in the fixture body is limited by the width of the battery to be placed in this recess, it is desirable to be able to miniaturize the fixture body without being limited by the width of the battery.

[0004] There is a demand for such lighting devices to be compact, but because the battery is placed in a recess in the main body of the fixture, the width between the side portions on either side of the recess is limited by the width of the battery, making it difficult to make the main body of the fixture compact.

[0024] The housing 40 includes a first housing 44, a second housing 45 to which the first housing 44 is joined, and a packing 46 that gives the housing 40 a waterproof structure. The light source section 41 is disposed on the rear side of the first housing 44, and the lighting unit 42 is disposed in the second housing 45, with the light source section 41 and the lighting unit 42 housed between the first housing 44 and the second housing 45. The first housing 44 and the second housing 45 are assembled detachably by screwing.

[0025] The first housing 44 is a decorative frame arranged outside the recess 23 of the fixture body 11. The front side of the first housing 44 has a surface portion 47 formed in a convex curved shape whose cross section in the width direction X protrudes downward so as to be continuous with the surface shape of the protruding region 12b of the regular light source unit 12. The maximum width in the width direction X of the first housing 44, that is, the maximum width in the width direction X of the surface portion 47, is formed wider than the width in the width direction X of the recess 23 of the fixture body 11 (the width between the inner surfaces of the left and right side portions 20 shown in FIG. 4) X1. The rear side of the surface portion 47 of the first housing 44 is formed in a concave shape, and a part of the light source portion 41 and the lighting unit 42 are arranged therein. Near the periphery of the rear side of the surface portion 47 of the first housing 44, a rectangular frame-shaped joint frame portion 48 that forms the first end portion 44a that faces the second housing 45 in the up-down direction is protruded. A maximum width X2 of the first end 44a in the width direction X (a width (distance) between outer portions of the left and right first end portions 44a shown in FIG. 4) is greater than a width X1 of the recess 23 of the fixture body 11 in the width direction X. Further, a plurality of holes 49 are provided in the surface portion 47 of the first housing 44. The holes 49 include a light source hole 50 provided substantially in the center of the surface portion 47 of the first housing 44 and facing the light source portion 41, and an inspection hole 51 provided at a distance on the side of the light source hole 50.

[0026] The second housing 45 includes an insertion portion 52 that is inserted into the recess 23 of the device body 11, and a flange portion 53 that forms a second end 45a that faces the first end 44a of the first housing 44.

[0027] The insertion portion 52 of the second housing 45 is provided in the shape of a rectangular box with an opening on the bottom side. The width of the insertion portion 52 in the width direction X is smaller than the width X1 of the recess 23 of the fixture body 11 in the width direction X, allowing the insertion portion 52 to be inserted into the recess 23. The insertion portion 52 is inserted into the recess 23 and attached to the fixture body 11 by screwing or the like. When the insertion portion 52 is inserted into the recess 23 and attached, the lower end side of the insertion portion 52 is located on the lower side, outside the recess 23. A holding portion 54 that holds and positions the lighting unit 42 is provided inside the insertion portion 52.

[0028] The second end 45a of the second housing 45 is thicker (wider in the width direction X) than the lower end of the insertion portion 52, and is formed in a rectangular frame shape that protrudes from the lower end of the insertion portion 52 in a flange-like shape. That is, the maximum width X3 of the second end 45a in the width direction X (the width (distance) between the outer ends of the left and right second end 45a shown in FIG. 4) is larger than the maximum width X4 of the insertion portion 52 in the width direction X. Furthermore, the second end 45a is arranged on the lower side, which is outside the recess 23 of the instrument body 11, in a state in which the insertion portion 52 is inserted and attached in the recess 23. The maximum width X3 of the second end 45a in the width direction X (the width (distance) between the outer ends of the left and right second end 45a shown in FIG. 4) is larger than the width X1 of the recess 23 of the instrument body 11 in the width direction X. The second end 45a is arranged inside the first housing 44 from the rear side of the first housing 44, and is arranged opposite to the upper surface side of the first end 44a in the up-down direction.

[0029] Furthermore, the opposing surfaces of the first end 44a of the first housing 44 and the second end 45a of the second housing 45 facing each other in the vertical direction are positioned below and outside the recess 23 of the instrument body 11 when the insertion portion 52 is inserted into and attached to the recess 23.

[0030] The packing 46 includes a first packing part 56 interposed between the first end 44a of the first housing 44 and the second end 45a of the second housing 45 to provide a waterproof structure, a second packing part 57 interposed between the light source part 41 around the light source hole part 50 to provide a waterproof structure, and a third packing part 58 closing the lighting hole part 51 to provide a waterproof structure. The third packing part 58 has light transmittance and is formed of a transparent or semi-transparent material such as silicone rubber. The first packing part 56 and the second packing part 57 may or may not have light transmittance. Note that the first packing part 56 is not limited to the example in which it is interposed between the first end 44a of the first housing 44 and the second end 45a of the second housing 45 to provide a waterproof structure, but may be interposed between the inner surfaces of both sides of the surface part 47 of the first housing 44 and the outer end surfaces of the second ends 45a on both sides of the second housing 45 facing the inner surfaces to provide a waterproof structure.

[0031] The first packing portion 56 and at least one of the second packing portion 57 and the third packing portion 58 may be integrally formed. For example, the first packing portion 56 and the second packing portion 57 may be integrally formed, the first packing portion 56 and the third packing portion 58 may be integrally formed from the material of the third packing portion 58, or the first packing portion 56, the second packing portion 57 and the third packing portion 58 may be integrally formed from the material of the third packing portion 58.

[0032] When the gasket 46 is formed as an integral unit, the integral gasket 46 is arranged along the inner surface on the rear side of the first housing 44, and by combining this first housing 44 with the light source unit 41 and the second housing 45, each gasket unit 56, 57, 58 is interposed at a predetermined position to provide a waterproof structure.

[0033] The light source unit 41 also includes an emergency light source 60, a heat sink 61, a socket 62, and a lens 63.

[0034] The light source 60 is a light emitting module in which a semiconductor light emitting element such as an LED or an organic EL element is mounted on a substrate.

[0035] The heat sink 61 is made of a metal plate, and the light source 60 is disposed on the heat sink 61 so as to be thermally connected thereto via a socket 62 .

[0036] The socket 62 sandwiches the light source 60 between the socket 62 and the heat sink 61, and is attached to the heat sink 61 by screws. The socket 62 is electrically connected to the light source 60, and is electrically connected to wiring from the lighting unit 42, electrically connecting the light source 60 and the lighting unit 42.

[0037] The lens 63 is formed in a convex lens shape that protrudes in the light irradiation direction, receives light emitted from the light source 60, and emits it with a predetermined light distribution. The lens 63 faces the light source 60 and is attached to the heat sink 61 by screwing. The light source unit 41 is disposed on the rear side of the first housing 44, and the lens 63 is disposed in the light source hole 50 of the first housing 44. A second packing unit 57 is interposed between the lens 63 and the first housing 44 around the light source hole 50 to provide a waterproof structure.

[0038] The lighting unit 42 is disposed in a second housing 45. A power connection line and a battery connection line 84 (see FIG. 7) are connected to the second housing 45 and are drawn out from the second housing 45. The power connection line is electrically connected to a power line drawn into the fixture body 11. The battery connection line 84 is electrically connected to the battery 14.

[0039] The lighting unit 42 includes a case 65 and a circuit section 66 housed in the case 65. The circuit section 66 of the lighting unit 42 includes a charging circuit that, when external power is supplied from an external power source, converts the external power into a predetermined charging power to charge the battery 14, and an emergency lighting circuit that, when the external power source fails, converts the power stored in the battery 14 into a predetermined lighting power and supplies it to the light source 60 to light it. The emergency lighting circuit is electrically connected to the light source 60 by a harness.

[0040] The lighting unit 42 includes an inspection section 67 disposed opposite the inspection hole 51. The inspection section 67 includes a receiver 68 for receiving wireless signals such as infrared signals transmitted from an external terminal such as a remote control, a transmitter 69 for transmitting inspection results to the external terminal, an inspection switch 70 for manually instructing inspection, and a monitor lamp 71 for displaying the inspection results, etc. The life of the battery 14 and any abnormalities in the light source 60 can be inspected via the inspection section 67.

[0041] As shown in Figs. 6 to 9, the battery 14 uses a rechargeable secondary battery. The battery 14 has a battery body and a rectangular box-shaped battery case 74 that houses the battery body. The battery 14 is formed such that the rectangular upper and lower main surfaces are the widest surfaces, and the width between the upper and lower main surfaces, which is the width in the vertical direction, is the smallest. The battery 14 is arranged in the battery arrangement section 27 of the fixture body 11 with the long side of the main surface along the longitudinal direction Y of the fixture body 11 and the short side of the main surface along the width direction X of the fixture body 11. The battery 14 has a relationship in which the height in the vertical direction is smaller than the height in the vertical direction of the recess 23 of the fixture body 11, and the width X5 in the width direction X is larger than the width X1 in the width direction X of the recess 23 of the fixture body 11. The battery 14 is provided with a connector 14a on an end surface facing the emergency light unit 13 to which a battery connection line 84 from the lighting unit 42 is electrically connected. The position of the connector 14a on the end face of the battery 14 is on one end side of the width direction X of the battery 14, and is positioned toward the opening 30 when the battery 14 is placed in the recess 23 of the main body 11.

[0042] The battery 14 is attached to the appliance body 11 by an attachment member 76. The attachment member 76 is formed, for example, from a metal plate in the shape of a tray on which the battery 14 is detachably placed from above. The attachment member 76 includes a rectangular mounting portion 77 on which the battery 14 is placed, and side portions 78 and end portions 79 that rise from the periphery of the mounting portion 77 and hold the peripheral surface of the battery 14.

[0043] One end surface 79 of the mounting member 76 is provided with a generally L-shaped locking piece 80 that is inserted into the locking hole 28 of the appliance body 11 and hooked onto the top surface 19. The other end surface 79 of the mounting member 76 is provided with a mounting piece 82 having an insertion hole 81 through which a fixing screw 29 is inserted. The locking piece 80 is then locked to the appliance body 11, and a nut 83, such as a wing nut, is screwed onto the fixing screw 29 that passes through the insertion hole 81 and protrudes below the mounting piece 82, whereby the mounting member 76 is detachably attached to the appliance body 11.

[0044] The battery 14, which is placed in the battery placement section 27 of the device body 11 by the mounting member 76, is placed within the recess 23 of the device body 11, and a portion of the battery 14 in the width direction X is inserted from the opening 30 of one side portion 20 of the recess 23 to the outside of the one side portion 20, and is placed across the recess 23 and the communicating space section 31 outside the one side portion 20.

[0045] When the battery 14 is disposed in the appliance body 11, one side of the battery 14 in the width direction X is raised in an inclined state, the battery 14 is inserted from one side in the width direction X into the recess 23 and inserted into the communicating space 31 through the opening 30 of the side surface portion 20 on one side, the other side of the battery 14 in the width direction X is raised to be parallel to the top surface portion 19 of the appliance body 11, and the mounting member 76 for holding the battery 14 is attached to the appliance body 11. When the battery 14 is removed from the appliance body 11, after removing the mounting member 76 from the appliance body 11, the other side of the battery 14 in the width direction X is lowered to be in an inclined state, and the one side of the battery 14 in the width direction X is removed from the communicating space 31 and the opening 30 of the side surface portion 20 on one side, and the battery 14 is taken out from the other side in the width direction X below the recess 23.

[0046] When the battery 14 is disposed in the device body 11, the dimension X6 in the width direction X of the battery 14 inserted into the opening 30 and disposed in the communication space 31 is smaller than the width X5 in the width direction X of the battery 14 disposed in the recess 23. Furthermore, the maximum value of the dimension X7 of the battery 14 inserted into the opening 30 and disposed in the communication space 31 is restricted to the dimension of the battery 14 abutting against the reflecting surface 21, and is smaller than the minimum value of the dimension X6 of the battery 14 disposed in the recess 23. The connector 14a of the battery 14 is disposed on the opening 30 side of the center line C in the width direction X of the device body 11. Furthermore, it is preferable that at least a part of the connector 14a is disposed at a position where the connector 14 is inserted into the opening 30.

[0047] When external power is supplied to the lighting device 10 from an external power source, the external power is supplied to the normal lighting unit of the normal light source unit 12 and the lighting unit 42 of the emergency light unit 13. In the normal light source unit 12, the normal lighting unit converts the external power into a predetermined lighting power and supplies it to the normal light source, so that the normal light source is turned on. In the emergency light unit 13, the charging circuit converts the external power into a predetermined charging power to charge the battery 14.

[0048] In addition, when the external power source fails and external power is no longer supplied to the lighting device 10, the normal light source unit 12 is turned off. The emergency light unit 13 operates with power from the battery 14, converts the power from the battery 14 into a predetermined lighting power, and supplies it to the light source 60, which then lights up.

[0049] Also, when inspecting the emergency light unit 13 of the lighting device 10, the worker operates the remote control to transmit an inspection signal to the inspection section 67 of the emergency light unit 13. When the lighting unit 42 of the emergency light unit 13 receives the inspection signal from the remote control at the receiving section 68 of the inspection section 67, it goes into inspection mode, turns on the light source 60 with the power of the battery 14, and judges the state of the light source 60 and the life of the battery 14. The inspection operation and the inspection result are displayed on the monitor lamp 71 of the inspection section 67. After the inspection is completed, the inspection section 67 transmits a signal of the inspection result. Then, the worker visually checks the lighting state of the light source 60 of the emergency light unit 13 and the monitor lamp 71, and also checks the inspection result received by the remote control to check the state of the emergency light unit 13. The inspection operation of the emergency light unit 13 can also be performed by operating the inspection switch 70.

[0050] In the lighting device 10, the housing 40 of the emergency light unit 13 is disposed in the recess 23 of the fixture body 11. The housing 40 is divided into a first housing 44 in which the light source section 41 is disposed and a second housing 45 in which the lighting unit 42 is disposed, and is configured by joining the first housing 44 and the second housing 45. The minimum width of the first housing 44 in the width direction X may be limited by the lens 63 of the light source section 41, etc.

[0051] In a configuration in which the first housing 44 and the second housing 45 are joined together, if the joint portion is disposed within the recess 23 of the fixture body 11, the minimum width of the width X1 of the recess 23 in the width direction X is also limited according to the width of the first housing 44 in the width direction X, which has a limited minimum width. Therefore, in such a lighting device 10, even if there is a demand to reduce the size of the fixture body 11 in the width direction X, it is often difficult to meet this demand.

[0052] In the lighting device 10 of the present embodiment, the second end 45a of the second housing 45, which is joined to the first end 44a of the first housing 44, is positioned outside the recess 23. Therefore, regardless of the width of the width direction X of the first housing 44 in which the light source unit 41 is arranged, even if the maximum width X3 in the width direction X of the second end 45a of the second housing 45 is larger than the width X1 in the width direction X of the recess 23, the width of the insertion portion 52 of the second housing 45 can be reduced, and the width X1 in the width direction X of the recess 23 of the fixture body 11 can be made smaller.

[0053] Furthermore, by positioning the second end 45a of the second housing 45 outside the recess 23, the first gasket part 56 that provides a waterproof structure between the first end 44a of the first housing 44 and the second end 45a of the second housing 45, and the second gasket part 57 and the third gasket part 58 of the hole part 49 of the first housing 44 are positioned close to each other, so that the gasket 46 can be configured as an integrated gasket, the number of parts can be reduced, and assembly can be improved.

[0054] Furthermore, by positioning the second end 45a of the second housing 45 outside the recess 23, the position between the first end 44a of the first housing 44 and the second end 45a of the second housing 45, which provides a waterproof structure using the gasket 46, and the position of the hole 49 of the first housing 44 are close to each other, so that the gasket 46 can be configured as an integrated gasket, thereby reducing the number of parts and improving assembly.

[0055] In the lighting device 10, the width X1 in the width direction X of the recess 23 of the fixture body 11, i.e., the width X1 between the inner side surfaces of the side surface portions 20 on both sides, is smaller than the width X5 in the width direction X of the battery 14 placed in the recess 23 of the fixture body 11. This is due to the miniaturization of the fixture body 11 in the width direction X, or the enlargement of the battery 14 in the width direction X due to an increase in the type of the battery 14 or the storage capacity of the battery 14.

[0056] In general, if the width X1 of the recess 23 in the width direction X of the device body 11 is smaller than the width of the battery 14 in the width direction X, it becomes difficult to place the battery 14 in the recess 23.

[0057] In the lighting device 10, by providing an opening 30 in one side surface portion 20, the battery 14 can be placed in the recess 23 with a portion of the battery 14 inserted through the opening 30. That is, by arranging one side of the battery 14 in the communication space portion 31 outside the one side surface portion 20 through the opening 30 provided in the one side surface portion 20, the battery 14 can be placed in the recess 23. This makes it possible to accommodate a reduction in the size of the fixture body 11 in the width direction X, or to accommodate a variety of batteries 14 or an increase in the size of the battery 14 in the width direction X.

[0058] In the above embodiment, an example was described in which the battery 14 is attached to the recess 23 of the fixture body 11 by the mounting member 76, but the mounting member 76 may be attached to the fixture body 11 on the communicating space 31 side, and the battery 14 may be arranged so that a part of the battery 14 is inserted through the opening 30 and positioned in the communicating space 31, and the remaining part is positioned on the recess 23 side.

[0059] Furthermore, since the dimension X7 of the battery 14 in the width direction X when inserted into the opening 30 and placed in the communicating space 31 is smaller than the dimension X6 in the width direction X when placed in the recess 23, the amount of protrusion of the battery 14 outward from the side surface portion 20 on one side is reduced, and the battery 14 can be placed without interference, for example, even when the reflective surface portion 21 is present outside the side surface portion 20 on one side or when there is another obstruction.

[0060] Furthermore, the maximum value of dimension X7 by which battery 14 is inserted into opening 30 and positioned in communicating space 31 is restricted to the dimension at which battery 14 abuts reflective surface 21 or other obstructing objects, and is smaller than the minimum value of dimension X6 by which battery 14 is positioned within recess 23. Therefore, due to the mass balance of battery 14 in the width direction X relative to one side surface 20, battery 14 can be prevented from falling outside one side surface 20 when being attached or detached, improving the ease of attachment and detachment.

[0061] 7, the connector 14a is disposed closer to the opening 30 than the center line C in the width direction X of the fixture body 11, and further, at least a part of the connector 14a is preferably inserted into the opening 30, so that the battery connection line 84 from the lighting unit 42 connected to the connector 14a can be wired off to one side of the side surface portion 20 on one side in the width direction X. This makes it possible to prevent attachment structures such as the suspension bolt 85 that passes through the attachment hole 26 provided in the center in the width direction X of the recess 23 of the fixture body 11 and the washer 86 and nut 87 for attaching the fixture body 11 to the suspension bolt 85 from interfering with the arrangement of the battery 14 or the wiring of the battery connection line 84.

[0062] Moreover, the openings 30 may be provided on both sides of the side surface portion 20 of the recess 23 so as to face each other.

[0063] In addition, by arranging the reflective surface portions 21 on the outside of the side portions 20 on both sides of the recess 23, the battery 14 that protrudes outward beyond one of the side portions 20 can be concealed, but this may also be applied to an appliance body 11 that has an approximately C-shaped cross section and does not have a reflective surface portion 21.

[0064] In the lighting device 10, the second end 45a of the second housing 45, which is joined to the first end 44a of the first housing 44, is positioned outside the recess 23, and the battery 14 can be positioned in the recess 23 with a portion of it inserted into the opening 30, so that the dimension of the recess 23 in the width direction X can be reduced, and the fixture body 11 can be made smaller in the width direction X.

[0065] The lighting device 10 can also be applied to a fixture structure that does not include the normal light source unit 12 and includes only the emergency light unit 13.

[0066] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
