[0003] [Patent Document 1] JP 2018-192881 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the lighting device as disclosed in the above-mentioned Patent Document 1, the lighting member is turned on and off by pressing one button which operates one switch. Here, for example, when the lighting device is applied to a vehicle, the power supply to the lighting device is interrupted by opening and closing the door. In a state where the final button pressing operation turns off the lighting member, the lighting member does not turn on even when the door is opened. On the other hand, in a state where the final button pressing operation turns on the lighting member, the lighting member turns on when the door is opened. For this reason, in a structure where the lighting member is turned on and off by pressing one button, the lighting member may turn on even when it is not desired to turn on the lighting member.

[0005] The present invention has been made in view of the problems inherent in the conventional techniques, and an object of the present invention is to provide a lighting device capable of suppressing unnecessary lighting. [Means for solving the problem]

[0006] The lighting device according to this embodiment includes a lighting member, a switch for turning the lighting member on and off when pressed, a button for pressing the switch, a light-off switch for turning the lighting member off when pressed and keeping the lighting member off, and a light-off button for pressing the light-off switch, and a regulating section is provided between the button and the light-off button for regulating the pressing of the button when the light-off button is pressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the lighting device according to the present embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for the convenience of explanation and may differ from the actual ratios.

[0010] As shown in Fig. 1, the lighting device 1 according to this embodiment is applied to, for example, a vehicle lighting device that illuminates the interior of a vehicle. The lighting device 1 is attached to, for example, a ceiling 103 (see Fig. 8) in the vehicle interior. The lighting device 1 attached to the ceiling 103 is operated by an operator such as a passenger in the vehicle.

[0011] As shown in FIGS. 1 to 7, the lighting device 1 includes a lighting member 3, a housing 5, a lens 7, a switch 9, a light-off switch 11, a button 13, and a light-off button 15.

[0012] As shown in Figs. 2 to 6, the illumination member 3 has a circuit board 17 on which a circuit pattern is formed. On one surface of the circuit board 17, a plurality of illumination units 19 (two in this example) each consisting of an LED or the like for illuminating the interior of the vehicle are provided. On the other surface of the circuit board 17, a connector 21 electrically connected to the circuit pattern is provided. The connector 21 supplies power to the circuit board 17 by, for example, fitting with a vehicle-side connector (not shown) electrically connected to a power source of the vehicle. The illumination member 3 is accommodated in a housing 5.

[0013] As shown in Figs. 1 to 6, the housing 5 is made of an insulating material such as synthetic resin. The housing 5 is formed in a casing shape that can be placed in a placement portion (not shown) formed by recessing the ceiling 103 (see Fig. 8). The housing 5 has a bottom wall 23, a peripheral wall 25 extending from an edge of the bottom wall 23 toward the opposite side to the ceiling 103, and an opening 27 that opens on the side of the peripheral wall 25 opposite the bottom wall 23. A circuit board 17 is fixed to the surface of the bottom wall 23 of the housing 5 facing the ceiling 103 via a fixing portion (not shown). The circuit board 17 fixed to the bottom wall 23 is covered by a cover 29 that is attached to the housing 5 via an engagement portion so that a fitting portion of the connector 21 is exposed to the outside.

[0014] A pair of locking pieces 31, 31 extend diagonally from the ceiling 103 side of the bottom wall 23 of the housing 5 toward the ceiling 103 side so as to be elastically deformable. The pair of locking pieces 31, 31 can be engaged with a pair of locking holes (not shown) formed penetrating the ceiling 103. The engagement of the locking pieces 31 with the locking holes maintains the state in which the housing 5 is disposed in the arrangement portion of the ceiling 103. The bottom wall 23 of the housing 5 is formed with an irradiation opening 33 penetrating the bottom wall 23 to expose the irradiation portion 19 toward the interior of the vehicle. The bottom wall 23 of the housing 5 is formed with a button arrangement portion 35 in which the switch 9, the light-off switch 11, the button 13, and the light-off button 15 are disposed, penetrating the bottom wall 23, and extending from the bottom wall 23 in a cylindrical shape toward the opposite side to the ceiling 103. The opening 27 of the housing 5 is closed by the lens 7.

[0015] As shown in FIG. 1, 3 to 6, the lens 7 is made of an insulating material such as a synthetic resin having transparency. The lens 7 is formed in a rectangular shape having an outer edge equivalent to the inner edge of the opening 27 of the housing 5 so that the opening 27 of the housing 5 can be closed. The outer edge of the lens 7 extends toward the housing 5 and is formed continuously in the circumferential direction so that the lens 7 can be accommodated inside the housing 5. The lens 7 is accommodated in the opening 27 of the housing 5 to close the opening 27, and is assembled to the housing 5 via an engagement part (not shown). The lens 7 is formed with a button opening 37 penetrating the lens 7, which exposes the button 13 and the light-off button 15 to the inside of the vehicle cabin. The lens 7 transmits light from the irradiation part 19 of the circuit board 17 accommodated in the housing 5. The circuit board 17 is provided with a switch 9 electrically connected to the circuit pattern and a light-off switch 11.

[0016] As shown in Figs. 1, 3 to 6, the switch 9 is, for example, a sealed switch in which a contact portion is integrally provided in a housing. The switch 9 is electrically connected to the irradiation portion 19 via a circuit pattern. The switch 9 turns on the irradiation portion 19 by pressing the contact portion, and turns off the irradiation portion 19 by pressing the contact portion again. A light-off switch 11 is disposed adjacent to the switch 9.

[0017] As shown in FIG. 1 and FIG. 3 to FIG. 6, the light-off switch 11 is, for example, a sealed switch in which a contact portion is integrally provided in a housing, and is disposed adjacent to the switch 9 on the circuit board 17. The light-off switch 11 is, for example, electrically connected to a power supply circuit of a circuit pattern. The light-off switch 11 cuts off the power supply to the circuit board 17 and turns off the irradiation unit 19 by pressing the contact portion. On the other hand, the light-off switch 11 supplies power to the circuit board 17 by pressing the contact portion again. Therefore, when power is supplied to the circuit board 17, the turning on and off of the irradiation unit 19 is selected depending on the state of the pressing operation of the switch 9. The switch 9 is assembled with a button 13 that presses the contact portion, and the light-off button 15 that presses the contact portion is assembled with the light-off switch 11.

[0018] As shown in FIG. 1 and FIG. 3 to FIG. 7, the button 13 is made of an insulating material such as synthetic resin. The button 13 is formed in a housing shape that covers the entire switch 9 and the inner surface of the button 13 is in contact with the contact portion of the switch 9. The button 13 is formed of a single member that covers the housing portion of the light-off switch 11 and has a housing-shaped opposing portion 39 that is opened so as to protrude the contact portion. The button 13 is assembled to the contact portion of the switch 9 so as to be movable in a direction in which the contact portion is pressed via an engagement portion (not shown) so as to move in conjunction with the contact portion. The button 13 assembled to the switch 9 is arranged in the button arrangement portion 35 of the housing 5, and the outer surface where the contact portion of the switch 9 is located is exposed from the button opening portion 37 of the lens 7. The portion of the button 13 exposed from the button opening portion 37 is pressed by an operator such as a passenger in the vehicle, and the contact portion of the switch 9 is pressed. The opposing portion 39 of the button 13 is arranged to move the light-off button 15.

[0019] As shown in FIG. 1 and FIG. 3 to FIG. 6, the light-off button 15 is made of an insulating material such as synthetic resin. The light-off button 15 is formed in a housing shape that covers the contact portion of the light-off switch 11 and the inner surface of the light-off button 15 is in contact with the contact portion of the light-off switch 11. The light-off button 15 is disposed so as to be able to contact a facing surface 41, which is an opening edge of the facing portion 39 of the button 13, so as to be adjacent to the pressing portion of the button 13. The facing surface 43 of the light-off button 15 with the facing portion 39 is set to have an area equal to or slightly smaller than the facing surface 41 of the facing portion 39 so that the entire area is located on the facing surface 41 of the facing portion 39. The light-off button 15 is assembled to the contact portion of the light-off switch 11 so as to be movable in conjunction with the contact portion in the pressing direction of the contact portion via an engagement portion (not shown). Light-off button 15 attached to light-off switch 11 is disposed in button arrangement portion 35 of housing 5, and the outer surface on which the contact portion of light-off switch 11 is located is exposed from button opening 37 of lens 7. The portion of light-off button 15 exposed from button opening 37 is pressed by an operator, such as a passenger on board the vehicle, to press the contact portion of light-off switch 11.

[0020] When the light-off button 15 is pressed, it presses the contact portion of the light-off switch 11 to turn off the irradiation portion 19 of the lighting member 3. When the light-off button 15 is pressed, the irradiation portion 19 is kept turned off, and the irradiation portion 19 does not light up even when the button 13 is pressed. Therefore, if the light-off button 15 is pressed, the irradiation portion 19 does not light up, and unnecessary lighting can be suppressed. If the button 13 can be pressed while the light-off button 15 is pressed, the irradiation portion 19 does not light up even when the button 13 is pressed, which gives the operator a sense of incongruity. Therefore, a restricting portion 45 is provided between the button 13 and the light-off button 15 to restrict the pressing operation of the button 13 while the light-off button 15 is pressed.

[0021] The restricting portion 45 has opposing surfaces 41 and 43 which face each other in the pressing direction of the opposing portion 39 of the button 13 and the light-off button 15. As shown in FIG. 4, the opposing surfaces 41 and 43 are in contact with each other when the button 13 and the light-off button 15 are not pressed. At this time, the irradiation portion 19 of the lighting member 3 is in the light-off state. As shown in FIG. 5, the opposing surfaces 41 and 43 are separated when the button 13 is pressed and the light-off button 15 is not pressed. At this time, the irradiation portion 19 of the lighting member 3 is in the light-on state. In either case, the light-off button 15 is not in a pressed state, and the button 13 can move between a pressed state and a released state, making it possible to press the button 13.

[0022] In a state where the button 13 and the light-off button 15 are not pressed (see FIG. 4), when the light-off button 15 is pressed, it moves in the pressing direction in conjunction with the button 13 via the opposing surfaces 41 and 43. In a state where the button 13 is pressed and the light-off button 15 is not pressed (see FIG. 5), when the light-off button 15 is pressed, it moves in the pressing direction so that the opposing surfaces 41 and 43 come into contact with each other. In a state where the button 13 and the light-off button 15 are pressed, the opposing surfaces 41 and 43 come into contact with each other as shown in FIG. 6. At this time, the irradiation section 19 of the lighting member 3 is in an off state. Even if the button 13 is pressed in a state where the light-off button 15 is pressed, the button 13 cannot move in the pressing release direction due to the contact of the opposing surfaces 41 and 43. Therefore, the button 13 cannot be pressed, and the operator does not feel uncomfortable. Since the facing surface 41 of the facing portion 39 is disposed over the entire area of ​​the facing surface 43 of the light-off button 15, a wide contact area can be obtained. Therefore, the restricting portion 45 can stably restrict the pressing operation of the button 13. Note that when the light-off button 15 is pressed, pressing the light-off button 15 again moves the light-off button 15 in the direction in which the button is released from the pressing, and the button 13 can be pressed.

[0023] Here, a plurality of (here, three) other lighting devices 101 are arranged around the lighting device 1 on the ceiling 103. The other lighting devices 101 have the same configuration as the lighting device 1 except for the light-off switch 11 and the light-off button 15. The other lighting devices 101 are electrically connected to the lighting device 1, for example, via a vehicle-side connector that is electrically connected to the connector 21. When the light-off switch 11 of the lighting device 1 is pressed by pressing the light-off button 15, a contact portion is pressed, and all of the other lighting devices 101 are turned off.

[0024] An example of turning on and off the other lighting devices 101 by pressing the off button 15 is shown in Figs. 8 to 10. In Figs. 8 to 10, ◯ indicates a turned on state, and - indicates an off state. As shown in Fig. 8, when the lighting device 1 is turned on and all the other lighting devices 101 are turned off, the button 13 is pressed and the off button 15 is not pressed (see Fig. 5). At this time, the button 13 of the other lighting devices 101 is not pressed. As shown in Fig. 9, when the lighting device 1 and all the other lighting devices 101 are turned on, the button 13 is pressed and the off button 15 is not pressed (see Fig. 5). At this time, the button 13 of the other lighting devices 101 is pressed.

[0025] In the state shown in Fig. 8 and Fig. 9, when the light-off button 15 of the lighting device 1 is pressed (see Fig. 6), the lighting device 1 and all other lighting devices 101 are turned off as shown in Fig. 10. Therefore, if the light-off button 15 is pressed, the lighting device 1 and the other lighting devices 101 will not be turned on, and unnecessary lighting can be suppressed. Note that the state shown in Fig. 10 can also be achieved when the button 13 and the light-off button 15 of the lighting device 1 and the buttons 13 of all other lighting devices 101 are not pressed (see Fig. 4).

[0026] Such an illumination device 1 includes an illumination member 3, a switch 9 that turns on and off the illumination member 3 when pressed, and a button 13 for pressing the switch 9. The illumination device 1 also includes a light-off switch 11 that turns off the illumination member 3 when pressed and keeps the illumination member 3 off, and a light-off button 15 that presses the light-off switch 11. A restriction unit 45 is provided between the button 13 and the light-off button 15 to restrict pressing of the button 13 when the light-off button 15 is pressed.

[0027] Even if the illumination member 3 is turned on by pressing the button 13, the illumination member 3 can be turned off by pressing the light-off button 15. When the light-off button 15 is pressed, the illumination member 3 is kept turned off, and the illumination member 3 will not be turned on even if the button 13 is pressed. Therefore, if the light-off button 15 is pressed, the illumination member 3 will not be turned on, and unnecessary lighting can be suppressed. In addition, when the light-off button 15 is pressed, the pressing of the button 13 is restricted by the restricting portion 45, so the operator does not feel uncomfortable.

[0028] Therefore, in such a lighting device 1, unnecessary lighting can be suppressed.

[0029] Moreover, the button 13 has a facing portion 39 which faces the entire surface of the light-off button 15 in the pressing direction. The restricting portion 45 is formed by facing surfaces 41, 43 between the light-off button 15 and the facing portion 39.

[0030] The restricting portion 45 is the opposing surfaces 41, 43 of the light-off button 15 and the opposing portion 39, and therefore the pressing operation of the button 13 can be restricted by the contact of the opposing surfaces 41, 43. The opposing surface 41 of the opposing portion 39 is disposed over the entire area of ​​the opposing surface 43 of the light-off button 15, and therefore a wide contact area can be obtained. Therefore, the restricting portion 45 can stably restrict the pressing operation of the button 13.

[0031] Furthermore, pressing the light-off button 15 turns off other lighting devices 101 disposed in the vicinity.

[0032] Therefore, by pressing the light-off button 15, the lighting device 1 and the other lighting devices 101 will not be turned on, and unnecessary lighting can be suppressed.

[0033] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment.

[0034] For example, in this embodiment, the lighting device is disposed on the ceiling inside the vehicle compartment, but the present invention is not limited to this, and the lighting device may be disposed on a side wall, a bottom wall, or the like inside the vehicle compartment.

[0035] The restricting portion is the opposing portion of the button and the opposing surface of the light-off button, but is not limited thereto. For example, the button and the light-off button are formed in the same housing. The button and the light-off button are provided with protruding portions that protrude toward each other. The positions of the protruding portions may be different in the pressing direction, and the protruding portions may be disposed so as to come into contact with the light-off button when it is pressed, and these protruding portions may be used as the restricting portion.
