  However, in the above Patent Documents 1 and 2, since the light source is controlled to be turned on and off based on the detection result of the touch sensor, after the light source is turned on, the user mistakenly touches the touch sensor. There is a risk of turning off the light source by operating.

  The present invention has been made in view of the above-described present situation, and an object thereof is to provide an indoor illumination lamp that is excellent in operability and responsiveness when a light source is turned on and can prevent erroneous light-off of the light source. .

1. Interior lighting lamp Embodiment 1 The interior illumination lamp according to the present invention includes an irradiation unit, a touch sensor, a switch, and a light source control unit described below. This room illumination lamp can further include, for example, a housing that supports the movable operation member of the irradiation unit and the switch.
Examples of the use of the interior illumination lamp include interior illumination of vehicles such as vehicles, ships, and airplanes, embedded illumination of furniture, and the like. In addition, examples of the indoor illumination lamp include a map lamp, a vanity lamp, a trunk lamp, a spot lamp, and a room lamp.

As long as the “irradiation part” has a light source, its configuration, shape, number, etc. are not particularly limited. The shape of the exposed portion of the irradiating portion on the indoor side can be arbitrarily selected, but the shape of the exposed portion is preferably a circle (particularly a true circle). It is because it is excellent in aesthetics. Moreover, this irradiation part can be rotatably supported by one or two rotating shafts with respect to the housing, for example. Thereby, the irradiation direction of a light source can be changed to an arbitrary direction at a wide angle. Furthermore, since the irradiation unit includes a light source, even if the irradiation direction of the irradiation unit is changed, the optical system such as the optical axis does not change, and uniform irradiation ability can be obtained. In particular, it is preferable to use a light source with high directivity, such as an LED, because there is no problem.
The type, shape, number, etc. of the light source are not particularly limited as long as the light source emits light electrically. This light source can be, for example, an LED. Thereby, compared with what uses a bulb | ball as a light source, spot property can be improved and size reduction can be achieved.

  The “touch sensor” is not particularly limited in its configuration, type, number, etc. as long as it detects contact and / or approach of the human body. This touch sensor is usually a light source lighting sensor. Examples of the type of the touch sensor include a capacitance type, a piezoelectric element type, a photoelectric type, and an ultrasonic type. Of these, the capacitive type is preferable from the viewpoint that the non-contact sensor can be configured easily and inexpensively. This capacitive touch sensor can include, for example, an electrode unit as a detection unit of the touch sensor and a capacitive circuit that detects a change in capacitance between the electrode unit and the human body.

As long as the “switch” has a movable operation member, its configuration, shape, number, etc. are not particularly limited. This switch is normally a switch for turning off the light source. Moreover, this switch can have the contact part from which a connection state switches according to the change of the position of a movable operation member, for example. The contact portion can have, for example, a contact (for example, a switch plate) provided on the movable operation member, and a contact pattern on the electronic substrate with which the contact comes into contact.
Examples of the movable operation member include a rotation operation member, a push button, and a slide lever. Among these, the rotation operation member is preferable from the viewpoint that malfunction can be suppressed. For example, the rotation operation member can be provided so as to be rotatable and positionable between a plurality of preset rotation positions. In addition, the rotation direction of this rotation operation member, the presence or absence of restrictions on the rotation angle range, etc. are not particularly limited.

The “light source control unit” is electrically connected to the light source, the touch sensor, and the switch, and controls the lighting of the light source without turning it off based on the detection result of the touch sensor. As long as the light source is not controlled to be turned on and turned off based on the operation state, its configuration, light source control mode, timing, etc. are not particularly limited.
For example, the light source control unit controls the lighting of the light source when a detection signal of a change in capacitance between the electrode unit and the human body is input from the capacitance circuit constituting the capacitance type touch sensor described above. In addition, the light source can be controlled to be turned off when the connection state of the contact portions constituting the switch is switched. As a form of this turn-off control, for example, (1) a form in which the light source is turned off each time the rotation position of the rotation operation member changes, and (2) a rotation operation member has a predetermined predetermined value among a plurality of rotation positions. For example, the light source can be turned off when positioned at the turn-off rotation position.

  Here, the detection part of the said touch sensor can be provided in the said movable operation member, for example. At this time, when the irradiation unit is rotatably supported on the housing by one or two rotation shafts, the user can move the movable operation member, that is, the touch sensor when changing the direction of the irradiation unit in the lighting state. However, since the lighting state does not change unless the movable operation member of the switch is operated, it is possible to prevent the irradiation unit from being turned off erroneously.

  When the detection unit is provided on the movable operation member as described above, as the capacitive touch sensor, for example, (1) the electrode unit as the detection unit is all on the surface side of the resin movable operation member. The form which consists of a metal plating layer provided in the area | region or one part area, (2) The form which the electrode part as said detection part consists of metal movable operation members, etc. can be mentioned. In the mode (1), it is preferable that the metal plating layer is provided in the entire region of the movable operation member on the exposed surface side and the non-exposed surface side on the indoor side. This is because the detection region of the touch sensor can be set in a wide range by the metal plating layer on the exposed surface side, and the metal plating layer on the non-exposed surface side and the capacitance circuit can be easily connected by wiring. Examples of the metal plating layer include chrome plating and gold plating.

When the detection unit is provided on the movable operation member as described above, the movable operation member of the switch has, for example, a ring shape provided so as to surround the irradiation unit, and rotates along the outer periphery of the irradiation unit. It can be supported freely.
In this case, the surface color of the movable operation member can be different from the surface color of the irradiation unit (for example, a lens holder, for example). The surface color of the movable operation member can be, for example, a metal color by the metal plating layer. As this metal color, for example, silver-white with chrome plating bluish color, golden color with gold plating, or the like can be used. Moreover, the surface color of this irradiation part can be various resin colors, for example.
In this case, for example, a plurality of concave portions and / or a plurality of convex portions can be formed on the surface side of the movable operation member. Examples of the plurality of concave portions and / or convex portions include dimple portions, rib portions, diamond cut portions, and the like. In this case, you may make it provide the recessed part and / or convex part of the same shape as the said recessed part and / or convex part of a movable operation member on the surface side of an irradiation part (for example, lens holder etc.), From the viewpoint of distinguishability, it is preferable to provide a concave portion and / or a convex portion having a shape different from that of the movable operation member on the surface side of the irradiation portion, or not to provide a concave portion and / or a convex portion on the surface side of the irradiation portion.
In this case, for example, the shape of the exposed portion of each of the irradiation unit, the movable operation member, and the housing on the indoor side may be a circle (preferably a true circle). Thereby, the design in which the irradiation part, the movable operation member, and the housing have the same circular shape can be obtained, and the design is different from the conventional rectangular indoor lighting device, so that the design can be improved. In this case, it is preferable that the irradiation unit, the movable operation member, and the housing are arranged concentrically. This is because the unity of each element is obtained, the design is different from that of the conventional rectangular indoor lighting device, and the design can be improved.

2. Interior Lighting Other Embodiments2. As the indoor lighting according to the first embodiment, for example, the above-described first embodiment. A support ring that is positioned inside a cylindrical support portion (e.g., a lens holder) that constitutes the irradiating portion and supports the support portion so as to be rotatable about a first rotation axis; The housing having a support column located inside the support ring and rotatably supporting the support ring around a second rotation axis that intersects (preferably orthogonally intersects) the first rotation axis. Can be mentioned. Thereby, the movable angle range of an irradiation part can be made into a wider angle, without exposing a support ring outside.

  Embodiment 2 above. In the indoor lighting, for example, the shaft disposition surface that supports the support ring of the support column is inclined closer to the axis of the support ring from the support front end side to the base end side of the support ring. it can. Thereby, the angle when the support portion and the support ring rotate to contact the support column can be made larger than when the shaft arrangement surface is a vertical surface, and the movable angle range of the irradiation portion can be made wider. .

  Embodiment 2 above. In the indoor illumination lamp, for example, a rib extending in the standing direction of the support column is provided on the shaft-disposed back surface that is the surface opposite to the shaft-disposed surface that supports the support ring of the support column. Can do. Thereby, the intensity | strength of a support pillar can be raised, without narrowing the angle which a support part and a support ring rotate.

  Embodiment 2 above. In the interior illumination lamp, for example, the shaft-arranged back surface of the support column can be inclined closer to the axis of the support ring from the support front end side to the base end side of the support ring. As a result, even if the irradiation unit rotates, it becomes difficult to make contact with the support column, the rotation angle of the irradiation unit can be made larger than when the rear surface of the shaft is a vertical surface, and the movable angle range of the irradiation unit is made wider. be able to.

3. Interior lighting lamp Still another embodiment 3. As the indoor lighting according to the first embodiment, for example, the above-described first embodiment. Or 2. In the interior illumination lamp according to the present invention, the irradiating part is supported by the housing via a connecting structure on at least one axis, and the connecting structure is a first connecting member and a second connecting member that are rotatable relative to each other. And a shim interposed between these connecting members and applying a load by friction during relative rotation, wherein the shim is a disk-shaped base portion having an outer peripheral surface as a friction surface A large-diameter disk shape having a larger diameter than the base portion, the outer peripheral surface of which is a friction surface, and is provided in a stepped manner continuously from the base portion, and from the large-diameter portion side in the axial direction. A fixed portion having a protruding prismatic shape, and the first connecting member includes a base portion receiving portion into which the base portion is rotatably fitted, and a large diameter portion into which the large diameter portion is rotatably fitted. A stepped shim receiving hole provided with a receiving portion, and the second connecting member includes a front Having a fixed portion receiver for non-rotatably fitted to the fixing portion may include those characterized by. Examples of the shim material include elastomer, rubber, resin, and the like.
Thereby, since the said shim is rotatably hold | maintained at the 1st connection member by making the outer peripheral surface of the base | substrate part and a large diameter part into a friction surface, compared with what uses a friction surface as an internal peripheral surface like before. Thus, a wider friction surface can be secured, the shim can be miniaturized, and the number of parts and man-hours can be reduced. Further, since the friction surface is formed in a step shape, it is possible to prevent the shim from dropping off and to prevent the shim from being assembled incorrectly. Moreover, since the base portion and the large-diameter portion of the shim are disk-shaped, when the shim is attached to a cylindrical surface or a spherical surface, it is possible to reduce the area of the plane required for attachment as compared with the conventional rectangular shape. The connection structure can be downsized.

  Embodiment 3 above. In the indoor illumination lamp, for example, a fixing recess made of a prismatic recess is further provided around the base of the fixing portion of the shim, and a tip of the fixing portion receiving portion of the second connecting member is formed in the fixing recess. It can be fitted non-rotatably. As a result, the shim and the second connecting member are fitted between the outer peripheral surface of the fixed portion and the inner peripheral surface of the fixed portion receiving portion, and between the inner peripheral surface of the fixed recess and the outer peripheral surface of the fixed portion receiving portion. Since they are fixed together, it is possible to increase the fixing force between the shim and the second connecting member and to prevent damage.

  Embodiment 3 above. In the indoor illumination lamp, for example, the shim receiving hole may be a through hole whose depth is the sum of the thicknesses of the base portion and the large diameter portion. Thereby, a shim receiving hole can be formed or processed easily, and a connection structure can be made into a small and simple structure.

4). Interior lighting lamp Still another embodiment 4. As the indoor lighting according to the first embodiment, for example, the above-described first embodiment. ~ 3. In the interior illumination lamp according to any one of the above, the housing that rotatably supports the irradiation unit and supports the movable operation member of the switch, the wire harness that connects the contact point of the switch and the light source, The irradiation section includes a light source side fixing member (for example, an LED hold plate) having light source side fixing means for fixing a part of the wire harness on the light source side, and the housing is on the switch side of the wire harness. A switch-side fixing member (for example, an outer plate) having a switch-side fixing means for fixing a part of the wire harness when the irradiation unit is rotated or moved with respect to the housing. Between the light source side fixing means and one end, and the switch Between the fixing means and the other end may include those characterized in that so as not to deform. Thereby, even when the wire harness is deformed, an external force does not act on the connector portion at the end, and disconnection at the attachment portion of the wire harness to each connector can be prevented.

  Embodiment 4 above. In the interior illumination lamp, for example, both of the light source side and the switch side fixing means can have a clamp structure. Thereby, a strong fixing force can be obtained with a simple structure. The clamp mechanism includes, for example, a pressing portion provided so as to be elastically deformable and fixing portions disposed on both ends of the pressing portion, and the pressing portion and the fixing portions in an inelastically deformed state. (S1, S2) can be set to a value smaller than the diameter of the wire harness. Thereby, since a wire harness can be made to bite in two places between a holding | suppressing part and each fixing | fixed part, a wire harness can be fixed more reliably.

  Embodiment 4 above. In the indoor lighting, for example, the switch side fixing member has a passage hole through which the wire harness is movably inserted, and the light source side fixing means is disposed in the vicinity of the passage hole. it can. Thereby, at the time of rotation or movement of an irradiation part, since the wire harness between each fixing means deform | transforms and bends so that a passage hole may be moved, possibility that it may bite into another member can be suppressed.

Two fixing portions 44 for holding the wire harness 38 between the pressing portion 45 and the pressing portion 45 are provided. The pressing portion 45 is provided integrally with the outer plate 10 and has elasticity. Moreover, the front-end | tip part of the holding | suppressing part 45 protrudes below in the hook shape so that the shift | offset | difference to the side of the wire harness 38 may be prevented. Each fixing portion 44 is integrally provided so as to protrude from the surface of the outer plate 10. The protruding height of each fixing portion 44 is set to such a height that the wire harness 38 can be connected to the switch-side connector 47 without difficulty. Thereby, even when the wire harness 38 is mounted, it is possible to prevent a load due to the bending of the wire harness 38 itself from being applied to a connection portion of the wire harness 38 to the switch-side connector 47.

  As shown in FIG. 12, the positional relationship between the fixing portion 44 and the holding portion 45 is that of the portion closest to the fixing portion 44 and the holding portions 45a and 45b before the wire harness 38 is attached, that is, in a state where no external force is applied. Interval (When the surface that holds the wire harness 38 is located outside the opposing space of each fixing portion 44, such as the holding portion 45a, the surface that holds the wire harness 38, such as the interval S1 and the holding portion 45b, In the case where it exists inside the opposing space 44, the interval S2) is set to a value smaller than the diameter of the wire harness 38. In this case, when the wire harness 38 is sandwiched between the pressing portion 45 and each fixing portion 44, the pressing portion 45 pushes the wire harness 38 into the facing space of each fixing portion 44 and fixes it.

  The light source side fixing means 40 is configured by a clamp structure in the same manner as the switch side fixing means 43, and the wire harness 38 is pushed and fixed between the two fixing parts and each fixing part.

  As shown in FIG. 13, the touch sensor 50 includes an electrode portion 51 made of a chromium plating layer provided on the entire exposed surface side and non-exposed surface side of the switch knob 26 on the indoor side (“detection according to the present invention”). And an electrostatic capacity circuit 53 on the electronic substrate 33 that is electrically connected to the electrode part 51. The capacitance circuit 53 detects a change in capacitance between the electrode unit 51 and the human body, and outputs a detection signal to the light source control unit 55. In addition, the electrostatic capacity circuit 53 and the electrode part 51 (chrome plating layer) are electrically connected via a wiring 52 (see FIG. 1) having a contact point 52a pressed against the electrode part 51.

  The light source controller 55 is electrically connected to the light source 2, the electrostatic capacity circuit 53 constituting the touch sensor 50, and the contact part 56 constituting the switch 5. The light source control unit 55 includes a CPU, a ROM, and a RAM (not shown). The RAM is used for temporary storage of data and the like, and the CPU executes a light source on / off process according to a control program stored in the ROM. . That is, as shown in FIG. 14, the light source control unit first determines whether or not a detection signal of a change in capacitance between the electrode unit 51 and the human body is input from the capacitance circuit 53 of the touch sensor 50. Is determined (step S1). As a result, when the detection signal is input (in the case of YES determination in step S1), the light source 2 is turned on (step S2). Next, it is determined whether or not the connection state of the contact portion 56 of the switch 5 has been switched (step S3). As a result, when the connection state of the contact portion 56 is switched (YES in step S3), the light source 2 is turned off (step S4). Then, it returns to step S1 and the above-mentioned series of light source on / off processing is repeatedly executed. Note that step S1 is also performed when no detection signal is input from the touch sensor 50 (NO determination at step S1) and when the connection state of the contact portion 56 of the switch 5 cannot be switched (NO determination at step S3). Returning to the above, the above-described series of light source on / off processing is repeatedly executed.

(2) Procedure for assembling room illumination lamp Next, a procedure for assembling the room illumination lamp 1 having the above configuration will be described.
First, as shown in FIG. 3, the LED holder 12 is mounted on the lens 3, the LED unit 11 is mounted on the lens 3, and the LED holder plate 13 is sandwiched to assemble an integrated object. Next, the wire harness 38 is connected to the LED unit 11. Next, the illuminating unit 4 is assembled by attaching the integrated object to the lens holder 7. Then, the support ring 8 to which the two shims 18 and 19 are attached is mounted inside the lens holder 7. At this time, the rotary shaft end 14 is supported by the bearing 20 and the shim 18 is supported by the shim receiving hole 15. Thereafter, the support ring 8 is attached to the outer plate 10. At this time, the rotating shaft end 23 of the outer plate 10 is supported by the bearing 16 and the shim 19 is supported by the shim receiver 24.

  On the other hand, the switch knob 26 is mounted inside the outer bezel 9. At this time, the flange 31 of the switch knob 26 is inserted into the guide hole 32 of the outer bezel 9. Then, the switch plate 27 and the switch spring 28 are mounted, and the pin 29 and the pin spring 30 are mounted. Subsequently, the outer plate 10 assembled with the irradiation unit 4 and the support ring 8 is attached to the outer bezel 9. Furthermore, the electronic board 33 is screwed to the outer side of the outer plate 10 and the wire harness 38 is connected to assemble the room lamp 1.

  When the interior lighting 1 assembled as described above is attached to the ceiling 35, as shown in FIG. 6, the claws 36 of the outer bezel 9 are hooked diagonally on the edge of the mounting hole of the ceiling 35, and then the opposite side is mounted. The engaging spring 37 is lifted and elastically deformed and pushed into the back of the ceiling 35. Thereby, the claw 36 and the engagement spring 37 are hooked on the back side of the ceiling 35, and the room illumination lamp 1 is attached to the ceiling 35.

(3) Operation of the interior illumination lamp Next, the operation of the interior illumination lamp 1 having the above configuration will be described.
First, when it is desired to turn on the interior lighting 1, the user holds the vicinity of the switch knob 26 or touches the surface of the switch knob 26 directly. Then, the touch sensor 50 detects the contact and / or approach of the human body, and the light source 2 is turned on by the light source controller 55 to which the detection signal is input.

  Next, when it is desired to change the irradiation direction of the irradiation unit 4, the user applies an external force so as to hold the irradiation unit 4 and change the irradiation direction. Then, as shown in FIGS. 7A to 7C, the irradiation unit 4 appropriately rotates with respect to the housing 6 via the first and second rotation axes R <b> 1 and R <b> 2. As a result, the irradiation unit 4 can irradiate an arbitrary position within the movable range. Here, since the shims 18 and 19 are used for the first and second rotation axes R1 and R2, the irradiation unit 4 is positioned and held at an arbitrary position.

  Next, when it is desired to turn off the room lamp 1, the user rotates the switch knob 26 to change its rotational position. Then, the connection state of the contact portion 56 of the switch 5 is switched, and the light source 2 is turned off by the light source control unit 55 that captures this switching.

(4) Effects of the Embodiment As described above, in the indoor lighting 1 of the present embodiment, the light source control unit 55 does not control the lighting of the light source 2 based on the detection result of the touch sensor 50 and controls the lighting of the switch 5. Since the light source 2 is not controlled to be turned on and off based on the operation state of the switch knob 26, the light source 2 can be easily and reliably turned on by the touch sensor 50 even in the dark or during driving at night. The operability when the light source is turned on can be improved. In addition, when a light source is turned on, an operation such as pressing a movable operation member is not required unlike a mechanical switch, so that the light source can be turned on immediately when necessary, thereby improving the responsiveness when the light source is turned on. it can. Further, since the light source 2 is turned off by operating the mechanical switch 5 instead of the touch sensor 50, the light source 2 in the lit state is not turned off even if the user accidentally touches and / or approaches the touch switch 50. The light source 2 can be prevented from being turned off erroneously.

  Further, in this embodiment, since the electrode part 51 of the touch sensor 50 is provided on the switch knob 26, the light source 2 can be turned on and off by the electrode part 51 and the switch knob 26 which are the same part, so that the user can change their position. Can be easily grasped, and operability can be further enhanced. Moreover, compared with what provides the structural member of the touch sensor 50 and the switch 5 separately, the installation place for the touch sensor 50 and the switch 5 can be saved, and the interior illumination lamp 1 can be reduced in size.

  In this embodiment, since the capacitive touch sensor is employed as the touch sensor 50, the non-contact sensor can be configured easily and inexpensively. In addition, since the electrode part 51 of the touch sensor 50 is composed of a chrome plating layer provided on the surface side of the resin switch knob 26, it is compared with one using a metal switch knob that functions as the electrode part of the touch sensor. Thus, the weight can be reduced. Furthermore, the position of the switch knob 26 is made easier by the chrome plating layer which is a metallic color (bluish silver white) that is different from the surface color (various resin colors) of the resin lens holder 7 and the housing 6. Can be grasped easily, and the aesthetics can be enhanced and the design can be improved.

  In this embodiment, the switch knob 26 is formed in a ring shape so as to surround the irradiation unit 4 and is supported by the housing 6 so as to be rotatable along the outer periphery of the irradiation unit 4. Compared with a mechanical switch having a button, a slide lever, etc., it is possible to prevent the user from accidentally rotating the switch knob 26 when the light source is turned on. In addition, after finding the irradiation unit 4 by groping, it is possible to easily find the switch knob 26 positioned around the irradiation unit 4 and rotate it as it is, so that the operability can be improved. Furthermore, the design of the irradiation unit 4 and the switch knob 26 can be made circular so that the aesthetic appearance does not change even if the viewing direction is changed, and the degree of design freedom is increased and the design can be improved.

  Further, in the present embodiment, the shape of the irradiation portion 4, the switch knob 26, and the exposed portion of the housing 6 on the indoor side is the same circular shape. Therefore, the design is different from that of a conventional rectangular indoor illumination lamp. Can be improved. Furthermore, since the irradiation unit 4, the switch knob 26, and the housing 6 are arranged concentrically, each element has a unified feeling, and has a design different from that of a conventional rectangular indoor lighting, further improving the design. Can be made.

  Furthermore, in the present embodiment, the irradiation unit 4 is supported by the two rotation axes R1 and R2 with respect to the housing 6, so that the irradiation direction of the irradiation unit 4 can be changed in a wide angle in an arbitrary direction. In this case, when changing the direction of the illuminating unit 4 in the lighting state, the human body may be brought into contact with and / or close to the touch sensor 50, but the lighting state does not change unless the switch knob 26 is operated. It is possible to prevent erroneous turn-off. Furthermore, since the irradiation unit 4 includes the light source 2, even if the irradiation direction of the irradiation unit 4 is changed, the optical system such as the optical axis does not change, and uniform irradiation capability can be obtained. In particular, it is preferable to use the light source 2 having high directivity such as LED without any problem.
