It is a top view which shows the terminal which comprises the vehicle-mounted illuminating device shown in FIG. It is an electrical block diagram of the terminal shown in FIG. It is a flowchart which shows the process sequence of CPU shown in FIG.

  Hereinafter, an in-vehicle illumination device according to an embodiment of the present invention will be described. An in-vehicle lighting device according to an embodiment of the present invention includes lighting installed in a vehicle interior, a control unit that controls the lighting, and a touch panel, and detects a detection target at a plurality of positions of the touch panel. A detection unit that detects the position or movement of the detection target, and when the detection unit detects the position or movement of the detection target, the control unit controls the illumination according to the detection result. To control.

  As a result, the position or movement of the detection target is detected by detecting the detection target at a plurality of positions, and the lighting is controlled. For example, spotlight is radiated to a position desired by the driver or the occupant in the passenger compartment. When driving or changing the radiation angle, the driver or occupant does not need to operate the indoor lighting switch on the vehicle's ceiling etc. Can be operated. Furthermore, the illumination can be operated with an intuitive operation of moving the detection target. Therefore, convenience can be improved.

  Further, since the position or movement of the detection target is detected by detecting the detection target at a plurality of positions, malfunctions can be avoided. Moreover, since the said detection part is comprised including the touch panel, if the small-sized touch panel which can be carried especially is integrated in a detection part, the passenger | crew of a backseat can also make illumination a desired state.

  Further, the detection unit may detect the detection target at a plurality of positions at different times, thereby detecting the movement of the detection target. Thereby, malfunction can be avoided more reliably.

  The detection target may be a human finger. Thereby, it is possible to control the illumination with a simple operation of moving the finger.

  Moreover, the radiation angle of the illumination may be adjustable by the control unit. Thereby, the radiation angle of illumination can be adjusted by an intuitive and simple operation.

  In addition, the movement of the person's finger may be a pinch-in operation in which the two fingers are brought close to each other while the two fingers are in contact with the touch panel, or a pinch-out operation in which the two fingers are separated. May be. Thereby, the radiation angle of illumination, that is, the irradiation range, can be adjusted with a simple operation of performing a pinch-in operation or a pinch-out operation with two fingers.

  Further, the radiation angle of the illumination may be reduced in the pinch-in operation, and the radiation angle of the illumination may be increased in the pinch-out operation. As a result, it is easy for a human to grasp the correspondence between the direction in which the finger is moved and the radiation angle of the illumination, that is, the size of the illumination range, so that the illumination can be operated with a more intuitive operation. .

  Moreover, the luminous intensity of the illumination may be adjustable by the control unit. Thereby, the luminous intensity of illumination can be adjusted with an intuitive and simple operation.

  Further, the movement of the person's finger may be a two-finger scrolling action of scrolling in a state where the two fingers of the person are in contact with the touch panel. Thereby, the luminous intensity of the illumination can be adjusted with a simple operation of scrolling with two fingers.

  In addition, in the two-finger scroll operation, the intensity of the illumination may increase when scrolling upward of the touch panel, and decrease when scrolling downward of the touch panel. Accordingly, it is easy for a human to grasp the correspondence between the direction in which the finger is moved and the intensity of the illumination, so that the illumination can be operated with a more intuitive and simple operation.

  The touch panel may be provided with a guide portion that guides upward or downward movement of the person's finger. Thereby, even in a situation where the position of the touch panel cannot be visually observed, the light source can be controlled while easily grasping the position of the touch panel.

  Moreover, the radiation direction of the illumination may be displaceable by the control unit. Thereby, the radiation direction of illumination can be displaced by an intuitive and simple operation.

  Further, the movement of the person's finger may be a swipe action or a flick action that traces the person's finger in contact with the touch panel. Thereby, the radiation direction of the illumination, that is, the irradiation position can be displaced by a simple operation of simply swiping or flicking the finger.

  Further, the radiation direction of the illumination may be displaced in the same direction as the direction in which the person's finger moves by the swipe operation or the flick operation. As a result, it is easy for a human to grasp the correspondence between the direction in which the finger is moved and the radiation direction of the illumination, that is, the irradiation position, so that the illumination can be operated with a more intuitive and simple operation. .

  Further, the chromaticity of light emitted by the illumination may be adjustable by the control unit. Thereby, the chromaticity of the light emitted from the illumination can be adjusted by an intuitive and simple operation.

  Further, the movement of the person's finger may be a two-finger scrolling action of scrolling in a state where the two fingers of the person are in contact with the touch panel. This makes it possible to adjust the chromaticity of the illumination with a simple operation that only requires a two-finger scroll operation.

  Further, the control unit may perform control so that the illumination does not irradiate a predetermined range. In particular, when the luminous intensity is high, the control unit may control the irradiation range so that it does not reach a predetermined range or is turned off. Thereby, for example, since the irradiation range does not reach the driver and the driver's face and the vicinity thereof, the safety can be improved.

  The predetermined range may include either one of the driver's face and the rear glass or both the driver's face and the rear glass. Thereby, it is possible to prevent the vicinity of the driver's face and the rear window (rear glass) from being irradiated. In this way, for example, the irradiation range does not reach the face of the driver or the driver of the vehicle running behind and the vicinity thereof, so that the safety can be further improved.

(Example)
Hereinafter, an in-vehicle illumination device according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 4, the in-vehicle lighting device 1 includes one lighting device 2 and a terminal 3 that controls the lighting device 2. As shown in FIGS. 1 to 3, the illumination device 2 includes a light source 5 (illumination), a housing 6 that supports the light source 5, a radiation angle changing mechanism 8 that changes the radiation angle of the light source 5, And a radiation direction changing mechanism 9 that changes the radiation direction. As shown in FIG. 5, the terminal 3 includes a touch panel 31 that detects the movement of a person's finger F as a detection target, and a radiation angle changing mechanism 8, a radiation direction changing mechanism 9, and the like according to the detection result by the touch panel 31. A CPU 32 (control unit, shown in FIG. 6) to be controlled and a synthetic resin frame portion 36 (guide portion) for protecting the peripheral edge of the touch panel 31 are provided.

  As shown in FIG. 4, the illuminating device 2 is attached to the ceiling R of the vehicle, for example, and is installed so that the light source 5 irradiates the driver and the occupant side, that is, the lower side.

  As shown in FIGS. 2 and 3, the light source 5 is fixed to a rotating body 7 described later that is supported by the housing 6 so as to be displaceable. In the present embodiment, a color variable LED is used as the light source 5. The color variable LED is changed to a color composed of preset three primary colors according to the detection result by the touch panel 31. Further, the color variable LED is changed to a preset light intensity according to the detection result by the touch panel 31. The light source 5 is changed to a color composed of three primary colors set in advance according to the detection result by the touch panel 31 without using the color variable LED, and in advance according to the detection result by the touch panel 31. It may be an LED other than a color variable LED that is changed to a set luminous intensity, an organic EL, or other various lamps.

  As shown in FIG. 3, the housing 6 is provided in a box shape with an opening (not shown), and covers the housing main body 61 attached to the ceiling R of the vehicle, and the opening of the housing main body 61. And a plate-like cover 62. The cover 62 is provided with an exposure hole 6a in which the rotating body 7 is disposed. The housing 6 supports the light source 5 via the rotating body 7.

  As shown in FIG. 3, the rotating body 7 includes a disk-shaped light source support 71 that supports the light source 5, and a lens support 72 that is formed in a dome shape and supports the radiation angle changing mechanism 8. . The light source support 71 supports the light source 5 so that the light source 5 faces downward in the initial state. Here, the initial state is an initial state in which the light source 5 is not changed in its radiation angle. For example, in this embodiment, the light source 5 is supported so that the radiation direction is directed downward in the vertical direction. It is a state.

  The lens support portion 72 is formed in an inverted conical shape whose diameter decreases as it goes downward, that is, in a substantially dome shape. An electric focus variable lens as the radiation angle changing mechanism 8 is fixed to the lens support portion 72 at a position where the light from the light source 5 is emitted. The light source 5 and the radiation angle changing mechanism 8 are arranged at positions aligned on a straight line.

  A light source 5 (color variable LED) and a radiation angle changing mechanism 8 (electric focus variable lens) are fixed to the rotating body 7 so as to be aligned on a straight line. The rotating body 7 is supported by the radial direction changing mechanism 9 so as to be freely displaceable by 360 degrees. Thus, when the rotating body 7 is displaced, the color variable LED and the electric focus variable lens are displaced 360 degrees in the same direction (same direction).

  As the radiation angle changing mechanism 8, as shown in FIG. 3, an electric focus variable lens (manufactured by Opto Science Co., Ltd., EL-10-30 series) may be used. This electric focus variable lens moves the focal length by changing the curvature of the lens according to the detection result by the touch panel 31. Thus, the electric variable focus lens condenses or emits the light from the light source 5 by moving the focal distance of the light from the light source 5, that is, by changing the radiation angle. The radiation angle changing mechanism 8 may be a lens or a filter that can collect and emit light by moving the focal length of light from the light source 5 without using an electric variable focal lens. .

  As shown in FIG. 3, the radial direction changing mechanism 9 includes a fixed base (not shown) supported by the housing 6, a first drive mechanism 91 that tilts the rotating body 7 in the arrow Y direction, and the rotating body 7 as an arrow. And a second drive mechanism 92 to which the rotating body 7 is fixed while being tilted in the X direction. The first drive mechanism 91 is supported by a fixed base. The second drive mechanism 92 is supported by the fixed base via the first drive mechanism 91. Thus, the second drive mechanism 92 is displaced in the arrow Y direction in conjunction with the movement of the first drive mechanism 91 in the arrow Y direction. In this embodiment, the arrow Y direction indicates the traveling direction of the vehicle, and the arrow X direction indicates the width direction of the vehicle orthogonal to the traveling direction.

  The first drive mechanism 91 includes a first motor M1, a first magnet 93 attached to the rotation shaft of the first motor M1, a first Hall element 94 that detects a magnetic change of the first magnet 93, and a first A first movable base (not shown) that is tilted in the direction of the arrow Y as the motor M1 is driven. The first motor M1 is supported by a fixed base, and its rotation shaft extends in the arrow Y direction. The first movable base is formed in a disk shape, and the central portion thereof is pivotally supported by the fixed base via the shaft portion.

  The second drive mechanism 92 includes a second motor M2, a second magnet 95 attached to the rotation shaft of the second motor M2, a second Hall element 96 that detects a magnetic change of the second magnet 95, and a second A second movable base (not shown) is provided that is tilted in the direction of the arrow X along with the driving of the motor M2 and to which the light source 5 is attached. The rotation axis of the second motor M2 is provided so as to extend in the arrow X direction. The second movable base is formed in a disk shape. And it arrange | positions so that it may become coaxial up and down in order of the 1st movable stand, the 2nd movable stand, and the rotation body 7. FIG. The center of the second movable table is pivotally supported by the first movable table.

  Such a radiation direction changing mechanism 9 displaces the first movable base and the second movable base by driving the first motor M1 and the second motor M2 according to the detection result by the touch panel 31, respectively. The rotating body 7 supported by these movable bases, that is, the color variable LED as the light source 5 and the electric focus variable lens as the radiation angle changing mechanism 8 are displaced 360 degrees. Here, the displacement amount (tilt) of the rotating body 7 can be obtained from the outputs of the first and second Hall elements 94 and 96. Thus, the radiation direction changing mechanism 9 tilts the rotating body 7 in the direction desired by the user to change the radiation direction of the light from the light source 5 to the direction desired by the user.

  In the present specification, “changing the emission direction of the light source 5” includes changing the optical axis of the light source and changing the direction of the light emission port. Moreover, when the light source 5 is provided with the cover 62 which covers the said light source 5, it includes changing the direction of the radiation | emission surface which the cover 62 has.

  The radiation direction changing mechanism 9 described above is an example of a configuration that displaces the direction of the rotating body 7 360 degrees together with the light source 5 and the radiation angle changing mechanism 8 (electric focus variable lens). Other configurations may be used as long as the radiation direction of 5 can be changed. In the present embodiment, the orthogonal coordinate system is used as the radiation direction changing mechanism 9, but a spherical coordinate system or a cylindrical coordinate system may be used as long as the radiation direction of the light source 5 can be changed.

  Such an illuminating device 2 is attached to the ceiling R of the automobile as shown in FIG. Further, as shown in the figure, the touch panel 31 is fixed to the door on the driver's seat side rear seat S3 side, with the upper surface of the touch panel 31 extending along the horizontal direction. In the present embodiment, an example will be described in which the lighting device 2 is arranged on the center ceiling R of the driver seat S1, the passenger seat S2, the driver seat side rear seat S3, and the passenger seat side rear seat S4. When the user touches with one finger near the corresponding position on the passenger seat side rear seat S4 in the touch panel 31 with the light source 5 turned off, the light emission direction from the light source 5 is the passenger seat side occipital seat side S4 side. Turn to. In addition, when the user performs a swipe operation or a flick operation with two fingers while the light source 5 is turned on, the radiation direction is changed in the same direction as the direction in which the human finger F moves. For example, as shown in FIG. 5, when a human finger moves to the right from the contact position of the finger F on the touch panel 31, the light emission direction from the light source 5 is from the passenger seat side occipital seat side S4. The driver seat side rear seat S3 is changed.

  As shown in FIG. 5, the touch panel 31 is formed in a rectangular shape formed in a panel shape. The touch panel 31 includes a plurality of sensors (not shown) arranged in a regular grid pattern in the vertical and horizontal directions. The touch panel 31 has an upper surface along the horizontal direction, a longitudinal direction along the vehicle width direction (arrow X direction), and a width direction along the vehicle traveling direction (arrow Y direction).

  The touch panel 31 includes a first sensor unit 33 that is a detection unit for controlling the light intensity, a second sensor unit 34 that is a detection unit for controlling the chromaticity of light, a light emission angle, And a third sensor unit 35 that is a detection unit for controlling the radiation direction. In the present embodiment, the first sensor unit 33 is provided at the right side end as viewed from the user, the second sensor unit 34 is provided at the left side end than the first sensor unit 33, and the third The sensor unit 35 is provided between the first sensor unit 33 and the second sensor unit 34.

  The frame part 36 is provided so as to protrude from the surface of the touch panel 31, and guides the upward or downward movement of the user's finger F at the step between the touch panel 31 and the frame part 36.

  In the present embodiment, an example in which the radiation direction of the light source 5 is changed toward each of the seats S3 and S4 has been described, but the radiation direction of the light source 5 may not be directed to each seat. For example, the radiation direction of the light source 5 may be emitted toward the outside of the vehicle (for example, the foot when the door is opened).

  In the present embodiment, one example of the lighting device 2 has been described, but two or more lighting devices 2 may be provided. In that case, the illumination device 2 may be provided in the vicinity of each of the seats S1, S2, S3, and S4, and may be provided at any position in the vehicle. Further, in this embodiment, one terminal 3 is provided for one lighting device, but one terminal 3 may be provided for a plurality of lighting devices, and each of the plurality of lighting devices is controlled. The same number may be provided.

  In the present embodiment, the touch panel 31, that is, the terminal 3, is fixed to the door on the driver seat side rear seat S3 side, but the present invention is not limited to this. The terminal 3 may be fixed at an arbitrary position in the vehicle, or may be detachably provided at an arbitrary position in the vehicle. Further, the terminal 3 may be portable.

  In the present embodiment, the touch panel 31 includes a first sensor unit 33 (first portion), a second sensor unit 34 (second portion), and a third sensor unit 35 (third portion). The first, second, and third sensor units 33, 34, and 35 are provided side by side, but the present invention is not limited to this. The 1st, 2nd, 3rd sensor parts 33, 34, and 35 may be provided up and down, and may be provided in arbitrary positions, respectively. In addition, the first sensor unit 33 is a detection unit for controlling the light intensity, the second sensor unit 34 is a detection unit for controlling the light chromaticity, and the third sensor unit 35 emits light. Although it is a detection part for controlling an angle and a radiation direction, this invention is not limited to this. As long as it controls the light source 5, the sensor units 33, 34, and 35 provided at any position may perform any control.

  In this embodiment, the frame portion 36 is used as the guide portion, but the present invention is not limited to this. The guide part may be a protrusion provided on the touch panel 31 extending vertically, and may be, for example, a protrusion provided linearly at regular intervals. The protrusions and protrusions may be a part of the touch panel 31, and may be a member different from the touch panel 31 made of synthetic resin, for example. In the case where the protrusions and protrusions are part of the touch panel 31, the light source 5 may be controlled by tracing the protrusions and protrusions in the extending direction, for example.

  Next, the electrical configuration of the in-vehicle lighting device 1 having the above-described configuration will be described with reference to FIG. As shown in FIG. 6, the CPU 32 is composed of, for example, a microcomputer, and drives two motors M <b> 1 and M <b> 2 (light emission direction) according to the output from the touch panel 31, the light intensity of the light source 5, and the light source 5. And the radiation angle (lens curvature) of the light source 5 are controlled.

  Here, the CPU 32 detects the movement of the finger F by detecting the position of the user's finger F at a plurality of positions in the touch panel 31 and at different times. Specifically, the movement of the finger is detected when the finger F moves while the finger F is in contact with the touch panel 31. Thus, the CPU 32 can accurately detect the movement of the finger F while avoiding malfunction.

  In this embodiment, the CPU 32 turns on the light source 5 when detecting an action (contact) with one finger by the user. At this time, the CPU 32 tilts the rotating body 7 toward the position of the vehicle corresponding to the absolute coordinate position of the touch panel 31 touched by the user. Here, when the CPU 32 detects the absolute coordinate position where the finger F touches the touch panel 31, the CPU 32 controls the motors M <b> 1 and M <b> 2 to incline the rotating body 7 so as to correspond to the absolute coordinate position. Thus, the radiation direction of the light source 5 is directed to the area of the vehicle corresponding to the absolute coordinate position on the touch panel 31. Further, the CPU 32 turns off the light source 5 when detecting that a certain period of time has passed with the user touching the touch panel 31 while the light source 5 is turned on.

  In addition, while the light source 5 is turned on, an action (swipe operation or additional lick operation) with one finger of the user is detected. That is, the touch panel 31 detects whether the user's finger F has moved from the movement source coordinate position on the touch panel 31 to the movement destination coordinate position. Furthermore, when the CPU 32 detects the relative coordinates (the coordinates representing the relative position between the movement source coordinate position and the movement destination coordinate position) that the finger F has moved on the touch panel 31, the CPU 32 corresponds to the relative coordinates. The rotating body 7 is tilted by controlling each of the motors M1 and M2. Thus, the radiation direction of the light source 5 is directed to the vehicle area corresponding to the relative coordinates. The swipe operation is an operation in which the user's finger slowly traces the surface of the touch panel 31, and the flick operation is an operation in which the user's finger traces the surface of the touch panel 31.

  Further, the CPU 32 performs control so that the irradiation range of the light source 5 does not reach a predetermined range in the vehicle. That is, the CPU 32 performs control so that light from the light source 5 is not emitted toward a predetermined range. Thereby, the vehicle-mounted illuminating device 1 can prevent the light from the light source 5 from irradiating the vicinity of the driver's face or the rear window (rear glass). Thus, for example, the light from the light source 5 is not emitted near the face of the driver or the driver of the vehicle running behind, so that safety can be improved. Further, the CPU 32 may perform control so that the irradiation range does not reach the predetermined range or is extinguished when the luminous intensity is larger than a predetermined luminous intensity. Thereby, for example, since it is not radiated near the face of the driver or the driver of the vehicle running behind, safety can be improved.

  In addition, when the CPU 32 detects that the first sensor unit 33 of the touch panel 31 is scrolled upward with two fingers in contact with each other, the CPU 32 emits light corresponding to the amount of movement of the two fingers moved upward. The light intensity is controlled so as to increase. In addition, when the CPU 32 detects that the first sensor unit 33 of the touch panel 31 is scrolled downward in a state where two fingers are in contact, the CPU 32 emits light corresponding to the amount of movement of the two fingers moved downward. The light intensity is controlled to be small.

  Further, when the CPU 32 detects that the second sensor unit 34 of the touch panel 31 is scrolled upward with two fingers in contact with each other, the chromaticity of the light emitted from the light source 5 is increased. Control is performed so that the color changes from blue, green, and red, where the wavelength gradually increases, at a stage corresponding to the amount of movement moved to. Further, when the CPU 32 detects that the second sensor unit 34 of the touch panel 31 is scrolled downward in a state where two fingers are in contact with each other, the chromaticity of the light emitted from the light source 5 is reduced. Control is performed so that the color changes from red, green, and blue, where the wavelength is gradually shortened, at a stage corresponding to the amount of movement.

  Alternatively, the CPU 32 uses, for example, a chromaticity diagram (CIE 1931) defined by the CIE (International Commission on Illumination) to use a value corresponding to the Y coordinate with respect to a predetermined X coordinate (that is, the X coordinate is an arbitrary fixed value, Y The color may be controlled so that the coordinates become a variation value according to detection).

  Alternatively, the CPU 32 detects that the second sensor unit 34 is scrolled in the vertical direction and the horizontal direction with two fingers in contact with the second sensor unit 34 so that the color is based on the coordinates of the CIE. You may control the color of the light source 5 so that it may become the color of the coordinate according to the movement amount of two fingers. In this case, in CIE1931, the horizontal axis (X) and the vertical axis (Y) indicate chromaticity, and X = 0.33 and Y = 0.33 indicate achromatic colors (white). In a state before the chromaticity of the light emitted by 5 is controlled, the chromaticity may be set such that X = 0.33, Y = 0.33, that is, an achromatic color (white). . That is, the chromaticity of the light emitted from the light source 5 may be set so that the initial values are X = 0.33 and Y = 0.33. Thus, when the user's two fingers move to the upper left starting from X = 0.33 and Y = 0.33, the color is controlled to green, and when the user's fingers move to the lower left The color may be controlled to blue, and when moving to the lower right, the color may be controlled to red.

  Further, when the CPU 32 detects that the third sensor unit 35 of the touch panel 31 has pinched in (the operation of bringing two fingers close together in a state in which two fingers are in contact with the touch panel 31), the two fingers approached. Control is performed so that the radiation angle of the light source 5 is reduced by a value corresponding to the amount of movement.

  In addition, when the CPU 32 detects that the third sensor unit 35 of the touch panel 31 has pinched out (an operation of separating two fingers while the two fingers are in contact with the touch panel 31), the two fingers are separated. Control is performed so that the radiation angle of the light source 5 increases by a value corresponding to the amount of movement.

  Next, the detailed operation of the in-vehicle lighting device 1 having the above-described configuration will be described with reference to FIG. FIG. 7 is a flowchart showing a processing procedure of the CPU 32 shown in FIG. As shown in the figure, the CPU 32 starts an operation in response to, for example, the ignition of a vehicle being turned on. First, the CPU 32 determines whether or not the light source 5 is turned on (step S1). If it is lit (Y in step S1), the process proceeds to step S2.

  On the other hand, when it is not lit (N in step S1), the CPU 32 determines whether or not there is an action with one finger (step S2). The action in step S2 is a tap. Here, the tap is an operation of touching the surface of the touch panel 31 for a moment as if the surface of the touch panel 31 is tapped lightly.

  If there is an action with one finger (Y in step S2), the light from the light source 5 is emitted to the position of the vehicle corresponding to the absolute coordinate position in the third sensor unit 35 of the touch panel 31 (step S3). . That is, lighting is started while changing the radiation direction of the light source 5. If there is no action with one finger (N in step S2), the process returns to step S1.

  On the other hand, it is lit (Y in step S1), an action on the touch panel 31 with one finger is detected (Y in step S4), and a certain time has elapsed with the finger touching the touch panel. If it is (Y in Step S5), the CPU 32 turns off the light source 5 (Step S6) and returns to Step S1. On the other hand, if an action with one finger is detected (Y in step S4) and a certain time has not elapsed (N in step S5), the CPU 32 changes the radiation direction to a position corresponding to the action. (Step S7), the process returns to step S1. The action in step S7 is a swipe operation or a flick operation. Here, the CPU 32 determines that the swipe operation or the flick operation has been performed when contact with the finger F is detected at a plurality of positions on the touch panel 31 at different times. Thus, the touch panel 31 detects the movement of the finger F by detecting the finger F at different times at a plurality of positions. Thereby, it is possible to reliably avoid malfunction. The swipe operation is an operation in which the user's finger slowly traces the surface of the touch panel 31, and the flick operation is an operation in which the user's finger traces the surface of the touch panel 31.

  When an action on the touch panel 31 with one finger is not detected (N in step S4), and an action with two fingers is detected (Y in step S8), the CPU 32 detects the first sensor on the touch panel 31. The unit 33 determines whether an action is detected (step S9). When an action is detected in the first sensor unit 33 (Y in step S9), the CPU 32 changes the luminous intensity of the light source 5 so as to have a value corresponding to the finger movement (step S10), and step Return to S1. The action in step S9 is a two-finger scrolling operation that scrolls upward or downward with two touches on the touch panel 31. At this time, the user's finger F is guided to move upward or downward by the step between the frame portion 36 and the touch panel 31. Thereby, even in a situation where the position of the touch panel 31 cannot be visually observed, the light source 5 can be controlled while easily grasping the position of the touch panel 31.

  The light intensity of the light source 5 is controlled by the CPU 32 so as to increase when scrolling upward of the touch panel 31 and decrease when scrolling downward of the touch panel 31 in the two-finger scroll operation. Accordingly, since it is easy for a human to grasp the correspondence between the direction in which the finger F is moved and the magnitude of the light intensity of the light source 5 (illumination), the illumination can be operated with an intuitive and simple operation.

  When no action is detected in the first sensor unit 33 (N in step S9), the CPU 32 determines whether or not an action is detected in the second sensor unit 34 (step S11). When an action is detected in the second sensor unit 34 (Y in step S11), the CPU 32 changes the color of the light source 5 so as to have a value corresponding to the finger movement (step S12). Return to step S1. The action in step S12 is a two-finger scrolling operation that scrolls upward or downward with two user fingers in contact with the touch panel 31. At this time, the user's finger F is guided to move upward or downward by the frame portion 36. Thereby, even in a situation where the position of the touch panel 31 cannot be visually observed, the light source 5 can be controlled while easily grasping the position of the touch panel 31.

  When the color of the light source 5 is scrolled toward the upper side of the touch panel 31 in the two-finger scrolling operation, the color of the light source 5 is shifted downward from the touch panel 31 so that the color gradually changes from blue, green, and red. When the screen is scrolled, the CPU 32 controls the color to change from red, green, and blue whose wavelengths gradually become shorter. Thereby, since it is easy for a human to grasp the correspondence between the direction in which the finger F is moved and the color of the light source 5 (illumination), the illumination can be operated with an intuitive and simple operation. .

  If no action is detected in the second sensor unit 34 (N in step S11), the CPU 32 determines whether or not a pinch-in operation is detected in the third sensor unit 35 (step S13). When a pinch-in operation is detected in the third sensor unit 35 (Y in step S13), the CPU 32 changes the radiation angle so as to decrease to a value corresponding to the finger operation (step S14). ), The process returns to step S1. In addition, when a pinch-out operation is detected in the third sensor unit 35 (Y in step S13), the CPU 32 changes the radiation angle so as to increase to a value corresponding to the finger operation. (Step S15), the process returns to Step S1. Here, the pinch-in operation is an operation in which the movement of the user's finger F brings the two fingers close together in a state where the two fingers of the user are in contact with the touch panel 31. The movement of the finger F is an operation of separating the two fingers while the two fingers of the user are in contact with the touch panel 31. As described above, the radiation angle of the light source 5 (illumination), that is, the irradiation range can be adjusted by a simple operation in which a pinch-in operation or a pinch-out operation is performed with two fingers F. Further, since it is easy for a human to grasp the correspondence between the direction in which the finger is moved and the radiation angle of the illumination, that is, the size of the illumination range, the illumination can be operated with a more intuitive operation.

  According to the embodiment described above, by detecting the light source 5 (illumination) installed in the passenger compartment, the CPU 32 (control unit) that controls the light source 5, and the user's finger F (detection target) at a plurality of positions. A touch panel 31 (detection unit) that detects the position or movement of the finger F. When the touch panel 31 detects the position or movement of the finger F, the touch panel 31 detects that the light source 5 is in accordance with the detection result. To control.

  As a result, the position or movement of the finger F is detected by detecting the finger F at a plurality of positions, and the light source 5 is controlled. For example, spot light is radiated to a position desired by the driver or the passenger in the vehicle interior. And when changing the radiation angle, the driver or the occupant can easily operate the light source F by moving the finger F without operating the switch of the lighting device 2 provided on the ceiling of the vehicle. 5 can be operated. Furthermore, the light source 5 can be operated by an intuitive operation of moving the finger F. Therefore, convenience can be improved.

  Further, since the position or movement of the finger F is detected by detecting the finger F at a plurality of positions, malfunctions can be avoided.

  The touch panel 31 detects the movement of the finger F by detecting the finger F at different times at a plurality of positions. Thereby, malfunction can be avoided more reliably.

  The finger F is a human finger. Thereby, the light source 5 can be controlled by a simple operation of moving the finger.

  In the present embodiment, the detection unit includes a touch panel. However, the detection unit may not be a touch panel dedicated to the lighting device 2. The detection unit may be configured to include a touch panel, and may be a touch panel of a smartphone, a laptop computer, or a game machine.

  Further, in this embodiment, the change of the luminous intensity, the change of the chromaticity, the change of the emission angle, and the change of the emission direction are described as an example of the control of the illumination, but the present invention is limited to this. is not. Any control can be used as long as it is a lighting control. The position and movement of a person's finger as a detection target for controlling the lighting can be any position and movement as long as the detection unit can detect the position at a plurality of positions. There may be.

  In this embodiment, the CPU 32 as the control unit performs a pinch-in operation, a pinch-out operation, and a two-finger scroll operation for operations for “detecting a human finger (detection target) at different times at a plurality of positions”. The swipe operation, the flick operation, and the like have been described as examples, but the present invention is not limited to this. The control unit may “detect a human finger (detection target) at a plurality of positions at the same time”. That is, the control unit may control the illumination by simultaneously bringing two fingers into contact with the touch panel 31.

  In this embodiment, an example in which the detection target is a human finger is described as an example, but the present invention is not limited to this. A sensing member such as a touch pen sensed by the touch panel 31 may be used.
