The instrument panel 101 is a front equipment part in which, for example, a meter, a monitor of a navigation system, a passenger seat airbag, and the like are accommodated. The steering wheel 102 is disposed at the front portion of the seat 104. The map lamp 103 is disposed on the ceiling of the vehicle 201, for example. The irradiation object 3 is a floor carpet mat, for example, and is disposed under the feet of a passenger sitting on the seat 104. The light source 50 is a room light such as a footlight (also referred to as a footlight or a footlamp), for example, and is disposed at a position where the foot of the occupant is irradiated.

図１に示すように、照明装置１は、開閉検出部１０、記憶部３０、制御部４０、および光源５０を備えている。また、光源５０は、第１光源５１と第２光源５２を備えている。   As illustrated in FIG. 1, the lighting device 1 includes an open / close detection unit 10, a storage unit 30, a control unit 40, and a light source 50. The light source 50 includes a first light source 51 and a second light source 52.

The opening / closing result includes open information indicating that the door 2 is detected to be opened and closed information indicating that the door 2 is detected to be closed. Note that the lighting state includes a change in brightness, lighting, and extinguishing.

記憶部３０は、ドア２の開閉状態に応じて、第１光源５１と第２光源５２の点灯状態を制御部４０が制御するための情報を記憶する。   The storage unit 30 stores information for the control unit 40 to control the lighting state of the first light source 51 and the second light source 52 according to the open / closed state of the door 2.

制御部４０は、記憶部３０が記憶する情報を用いて、開閉検出部１０が出力した開閉情報に応じて、第１光源５１と第２光源５２の点灯状態を変化させるように制御する。なお、制御部４０が行う第１光源５１と第２光源５２の点灯状態の制御については、後述する。   The control unit 40 uses the information stored in the storage unit 30 to control the lighting states of the first light source 51 and the second light source 52 to be changed according to the opening / closing information output by the opening / closing detection unit 10. The control of the lighting state of the first light source 51 and the second light source 52 performed by the control unit 40 will be described later.

The irradiation object 3 has printing with invisible ink that cannot be visually recognized by the naked eye. For example, when the irradiation object 3 is irradiated with light from the second light source 52, printing is performed in which characters, patterns, and the like appear on the irradiation object 3.

次に、制御部４０が行う第１光源５１と第２光源５２の点灯状態の制御の例を説明する。
図３は、本実施形態に係る制御部４０が行う第１光源５１と第２光源５２の点灯状態の制御のタイミングチャートである。図３において、横軸は時刻を表す。波形ｇ１は、ドアの開閉状態を表す。波形ｇ２は、第１光源５１の輝度を表し、０が消灯、ｍａｘが最大輝度を表す。また、波形ｇ４は、第２光源５２の輝度を表し、０が消灯、ｍａｘが最大輝度を表す。また、本実施形態では、図３における時刻ｔ１から時刻ｔ８を含む一連の動作を演出動作という。 Next, an example of control of the lighting state of the first light source 51 and the second light source 52 performed by the control unit 40 will be described.
FIG. 3 is a timing chart of control of lighting states of the first light source 51 and the second light source 52 performed by the control unit 40 according to the present embodiment. In FIG. 3, the horizontal axis represents time. A waveform g1 represents the open / closed state of the door. A waveform g2 represents the luminance of the first light source 51, where 0 is extinguished and max is the maximum luminance. A waveform g4 represents the luminance of the second light source 52, where 0 is extinguished and max is the maximum luminance. In the present embodiment, a series of operations including time t1 to time t8 in FIG.

時刻ｔ１において、制御部４０は、開閉検出部１０が出力した開閉情報に応じて、ドア２が開いていると判別する。
時刻ｔ１から時刻ｔ２の期間（第１の所定時間）、制御部４０は、第１光源５１の輝度を０からｍａｘに上げていく（増光ともいう）。 At time t1, the control unit 40 determines that the door 2 is open according to the opening / closing information output by the opening / closing detection unit 10.
During a period from time t1 to time t2 (first predetermined time), the control unit 40 increases the luminance of the first light source 51 from 0 to max (also referred to as light increase).

時刻ｔ２から時刻ｔ３の期間（第２の所定時間）、制御部４０は、第１光源５１の輝度ｍａｘを維持する。なお、維持する輝度は、ｍａｘに限られず、予め定められた輝度であってもよい。   During the period from time t2 to time t3 (second predetermined time), the control unit 40 maintains the luminance max of the first light source 51. Note that the luminance to be maintained is not limited to max, and may be a predetermined luminance.

時刻ｔ３から時刻ｔ４の期間（第３の所定時間）、制御部４０は、第１光源５１の輝度ｍａｘから０に下げ（減光ともいう）つつ、第２光源５２の輝度を０からｍａｘに上げていく。なお、時刻ｔ３は、ドア２が閉まるタイミングである時刻ｔ４であってもよい。また、第３の所定時間は、第１の所定時間と同じでもよい。   During a period from time t3 to time t4 (third predetermined time), the control unit 40 decreases the luminance of the second light source 52 from 0 to max while decreasing the luminance max of the first light source 51 from 0 (also referred to as dimming). I will raise it. Note that time t3 may be time t4, which is the timing at which the door 2 is closed. Further, the third predetermined time may be the same as the first predetermined time.

時刻ｔ５から時刻ｔ７の期間（第４の所定時間）、制御部４０は、第２光源５２の輝度ｍａｘを維持する。なお、維持する輝度は、ｍａｘに限られず、予め定められた輝度であってもよい。また、制御部４０は、一連の演出動作が終了していない時刻ｔ６のときに再びドア２が開かれた場合、この検出結果をマスクして検出しないようにしてもよい。また、第４の所定時間は、第２の所定時間と同じでもよい。   During a period from time t5 to time t7 (fourth predetermined time), the control unit 40 maintains the luminance max of the second light source 52. Note that the luminance to be maintained is not limited to max, and may be a predetermined luminance. In addition, when the door 2 is opened again at time t6 when the series of rendering operations has not ended, the control unit 40 may mask this detection result so that it is not detected. Further, the fourth predetermined time may be the same as the second predetermined time.

図５は、本実施形態に係る制御部４０が行う処理のフローチャートである。
（ステップＳ１）制御部４０は、開閉検出部１０が出力する開閉情報に基づいて、ドア２が開いているか否かを判別する。制御部４０は、ドア２が開いていると判別した場合（ステップＳ１；ＹＥＳ）、ステップＳ２に処理を進め、ドア２が閉じていると判別した場合（ステップＳ１；ＮＯ）、ステップＳ１の処理を繰り返す。 Next, an example of a processing procedure performed by the control unit 40 will be described.
FIG. 5 is a flowchart of processing performed by the control unit 40 according to the present embodiment.
(Step S <b> 1) The control unit 40 determines whether the door 2 is open based on the opening / closing information output by the opening / closing detection unit 10. When it is determined that the door 2 is open (step S1; YES), the control unit 40 proceeds to step S2, and when it is determined that the door 2 is closed (step S1; NO), the process of step S1 repeat.

Thereby, the printed matter printed on the irradiation object 3 is visually recognized by the occupant so as to gradually emerge.
(Step S5) The controller 40 turns on the second light source 52 by maintaining the luminance of the second light source 52 for a fourth predetermined time. Thereby, a passenger | crew visually recognizes that the display of the printed matter printed on the irradiation target object 3 is continued.

（ステップＳ６）制御部４０は、開閉検出部１０が出力する開閉情報に基づいて、ドア２が開いているか否かを判別する。制御部４０は、ドア２が開いていると判別した場合（ステップＳ６；ＹＥＳ）、ステップＳ８に処理を進め、ドア２が閉じていると判別した場合（ステップＳ６；ＮＯ）、ステップＳ７に進める。 (Step S <b> 6) The control unit 40 determines whether or not the door 2 is open based on the opening / closing information output by the opening / closing detection unit 10. When it is determined that the door 2 is open (step S6; YES), the control unit 40 proceeds to step S8, and when it is determined that the door 2 is closed (step S6; NO), the control unit 40 proceeds to step S7. .

（ステップＳ７）ドア２が閉じていると判別した場合、制御部４０は、第５の所定時間、第２光源５２の輝度を徐々に下げてく。これにより、照射対象物３上に印刷された印刷物が、徐々に消えていくように乗員に視認される。制御部４０は、ステップＳ７の処理後、処理を終了する。または、制御部４０は、ステップＳ７の処理後、ステップＳ１の処理に戻す。 (Step S7) When it is determined that the door 2 is closed, the control unit 40 gradually decreases the luminance of the second light source 52 for a fifth predetermined time. Thereby, the printed matter printed on the irradiation object 3 is visually recognized by the passenger so as to gradually disappear. The control part 40 complete | finishes a process after the process of step S7. Or the control part 40 returns to the process of step S1 after the process of step S7.

（ステップＳ８）ドア２が開いていると判別した場合、制御部４０は、第５の所定時間、第２光源５２の輝度を徐々に下げていきつつ、第１光源５１の輝度を徐々に上げていく。これにより、照射対象物３上に印刷された印刷物が、徐々に消えていくように乗員に視認され、さらに乗員の足下が第１光源５１の光によって徐々に照らされていく。 (Step S8) When it is determined that the door 2 is open, the control unit 40 gradually increases the luminance of the first light source 51 while gradually decreasing the luminance of the second light source 52 for the fifth predetermined time.

In the example shown in FIG. 5, the timing at which the door 2 is closed is used as the trigger signal. However, the timing at which the door 2 is closed, or both the opening timing and the closing timing may be used. For example, when the timing at which the door 2 is closed is used, the control unit 40 determines that the door 2 is open in step S1, and then performs the processing after step S2 when determining that the door 2 is closed. You may do it.

図４、図５に示したように、本実施形態では、車両２０１のドア２が開かれたとき、まず、第１の所定時間の期間、第１光源５１の輝度が徐々に上がり、その後、第２の所定時間の期間、第１光源５１に輝度が維持される。そして、本実施形態では、第３の所定期間、第１光源５１の輝度が徐々に下がりつつ、第２光源５２の輝度が徐々に上がることで、照射対象物３上に不可視インク等で印刷された印刷物が第２光源５２の輝度に応じて徐々に浮かび上がってくる。そして、本実施形態では、第４の所定期間、第２光源５２の輝度を維持することで、照射対象物３上に印刷された印刷物が表示され続ける。そして、本実施形態では、第５の所定期間、少なくとも第２光源５２の輝度を徐々に下げることで、照射対象物３上に印刷された印刷物が第２光源５２の輝度に応じて徐々に消えていく。以上のように、本実施形態では、トリガ信号としてドア２が開けられたとき、上記の一連の演出動作を行うことができるので、単にドア２の開閉に応じて光源を点灯させたり消灯させる照明装置と比較して、照明装置１の商品性を向上させることができる。   As shown in FIGS. 4 and 5, in this embodiment, when the door 2 of the vehicle 201 is opened, first, the luminance of the first light source 51 gradually increases during a first predetermined time period, and then The brightness of the first light source 51 is maintained during the second predetermined time period. In the present embodiment, the brightness of the first light source 51 gradually decreases and the brightness of the second light source 52 gradually increases during the third predetermined period, so that printing is performed on the irradiation target 3 with invisible ink or the like. The printed matter gradually emerges according to the brightness of the second light source 52. In this embodiment, the printed matter printed on the irradiation object 3 is continuously displayed by maintaining the luminance of the second light source 52 for the fourth predetermined period. In this embodiment, the printed matter printed on the irradiation object 3 gradually disappears in accordance with the luminance of the second light source 52 by gradually lowering the luminance of the second light source 52 at least for the fifth predetermined period. To go. As described above, in the present embodiment, when the door 2 is opened as a trigger signal, the above-described series of presentation operations can be performed. Therefore, illumination that simply turns on and off the light source according to the opening and closing of the door 2 Compared with the device, the merchantability of the lighting device 1 can be improved.

When it is desired to obtain an effect, a desired effect can be obtained by simply replacing the desired irradiation object 3. Since the irradiation object 3 is a floor carpet mat or a seat cover of the seat 104, the user can easily replace it.

なお、図７に示した例では、第１光源５１を点灯、第１光源５１を消灯しつつ第２光源５２を点灯、第２光源５２を消灯する例を説明したが、これに限られない。操作部２０のスイッチが押された回数、または操作部２０の各スイッチが押されたとき、制御部４０は、第１光源５１を点灯、第１光源５１を点灯しつつ第２光源５２を消灯、第１光源５１を消灯、第１光源５１を消灯しつつ第２光源５２を点灯、第２光源５２を点灯、および第２光源５２を消灯のうちの少なくとも１つを行うようにしてもよい。
例えば、トリガ信号を検出したときに第１光源５１を消灯させることで、フロアマット自体（フロアマットの地模様）を視認できなくすることが可能となる。また、トリガ信号を検出したときに第１光源５１を点灯させることで、足下を照らすことができる。また、トリガ信号を検出したときに第１光源５１を点灯しつつ第２光源５２を消灯することで、フロアマットに印刷された文字や模様が消えていくように見せることができる。また、トリガ信号を検出したときに第１光源５１を消灯しつつ第２光源５２を点灯することで、フロアマットに印刷された文字や模様が表示されていくように見せることができる。また、トリガ信号を検出したときに第２光源５２を消灯させることで、フロアマットに印刷された文字や模様の表示を行わないようにすることができる。また、トリガ信号を検出したときに第２光源５２を点灯させることで、フロアマットに印刷された文字や模様の表示することができる。 In the example illustrated in FIG. 7, the example in which the first light source 51 is turned on, the second light source 52 is turned on while the first light source 51 is turned off, and the second light source 52 is turned off has been described. . When the switch of the operation unit 20 is pressed, or when each switch of the operation unit 20 is pressed, the control unit 40 turns on the first light source 51 and turns off the second light source 52 while turning on the first light source 51. Further, at least one of turning off the first light source 51, turning on the second light source 52 while turning off the first light source 51, turning on the second light source 52, and turning off the second light source 52 may be performed. .
For example, when the trigger signal is detected, the first light source 51 is turned off, so that the floor mat itself (the ground pattern of the floor mat) can be made invisible. Further, when the trigger signal is detected, the first light source 51 is turned on to illuminate the feet. Further, by turning off the second light source 52 while turning on the first light source 51 when the trigger signal is detected, it is possible to make characters and patterns printed on the floor mat disappear. Further, when the trigger signal is detected, the second light source 52 is turned on while the first light source 51 is turned off, so that characters and patterns printed on the floor mat can be displayed. Further, by turning off the second light source 52 when the trigger signal is detected, it is possible to prevent display of characters and patterns printed on the floor mat. Further, by turning on the second light source 52 when the trigger signal is detected, it is possible to display characters and patterns printed on the floor mat.

次に、制御部４０が行う処理手順の一例を説明する。
図８は、本実施形態に係る制御部４０が行う処理のフローチャートである。なお、図８に示す例は、操作部２０が、１つのスイッチのみを備える例である。 Next, an example of a processing procedure performed by the control unit 40 will be described.
FIG. 8 is a flowchart of processing performed by the control unit 40 according to the present embodiment. The example illustrated in FIG. 8 is an example in which the operation unit 20 includes only one switch.

（ステップＳ１０１）制御部４０は、操作部２０のスイッチが押された回数をカウントするカウント値Ｎを０に設定する。
（ステップＳ１０２）制御部４０は、操作部２０のスイッチが押されたか否かを判別する。制御部４０は、スイッチが押されたと判別した場合（ステップＳ１０２；ＹＥＳ）、ステップＳ１０３の処理に進め、スイッチが押されていないと判別した場合（ステップＳ１０２；ＮＯ）、ステップＳ１０１の処理を繰り返す。 (Step S <b> 101) The control unit 40 sets a count value N that counts the number of times the switch of the operation unit 20 is pressed to 0.

（ステップＳ１０６）制御部４０は、カウント値Ｎに１を加算する。
（ステップＳ１０７）制御部４０は、カウント値Ｎが２であるか３であるか４であるかを判別する。制御部４０は、カウント値Ｎが２であると判別した場合（ステップＳ１０７；Ｎ＝２）、ステップＳ１０８に処理を進め、カウント値Ｎが３であると判別した場合（ステップＳ１０７；Ｎ＝３）、ステップＳ１０９に処理を進め、カウント値Ｎが４であると判別した場合（ステップＳ１０７；Ｎ＝４）、ステップＳ１１０に処理を進める。 (Step S <b> 106) The control unit 40 adds 1 to the count value N.
(Step S107) The control unit 40 determines whether the count value N is 2, 3 or 4. When it is determined that the count value N is 2 (step S107; N = 2), the control unit 40 proceeds to step S108, and when it is determined that the count value N is 3 (step S107; N = 3). ), The process proceeds to step S109, and if it is determined that the count value N is 4 (step S107; N = 4), the process proceeds to step S110.

（ステップＳ１０８）制御部４０は、第１０の所定期間、第１光源５１を点灯させ、ステップＳ１０６の処理に戻す。
（ステップＳ１０９）制御部４０は、第１光源５１を消灯させ、かつ第１１の所定期間、第２光源５２を点灯させ、ステップＳ１０６の処理に戻す。 (Step S108) The controller 40 turns on the first light source 51 for the tenth predetermined period, and returns to the process of step S106.
