従来の技術は叙上の構成であるので次の課題が存在した。
すなわち図5に示す従来技術に於いては、例えば自動車の助手席に着座した乗員が車内で化粧等を行う際には、前記サンバイザー1の前記操作つまみ8をON方向に操作して電球7を点灯状態にして自分の顔面等を照射した後、別途に用意した鏡によって顔面等を視認する必要があり、一方の手で例えば化粧品を保持しかつ他方の手で鏡を保持しなければならないので両手がふさがり作業性が悪いという問題点があった。また、夜間走行中に上記した化粧等の作業を行うときは連続的に前記電球7を点灯状態にすることとなり、明るく照明された顔面や車内の様子が長時間に渉りフロントガラスの内側に映り込み運転席スペースも極端に明るく、運転者は車外の暗い風景を視認することが困難になり自動車を安全に運転できないうえに照明エネルギーが損失するという問題点があった。また、従来の技術に於いては鏡付サンバイザーも存在したが、乗員の顔を該鏡付サンバイザーに近接させても照度を変化させることができず常に照明したままで化粧用鏡としては不適切であり加えて照明エネルギーの損失を防止的ないという問題点があった。
Since the conventional technology has the above configuration, the following problems existed.
That is, in the prior art shown in FIG. 5, for example, when an occupant seated in a passenger seat of a car performs makeup or the like in the vehicle, the operation knob 8 of the sun visor 1 is operated in the ON direction so that the light bulb 7 After illuminating your face etc. with the light on, you need to visually check the face etc. with a separately prepared mirror, for example you must hold cosmetics with one hand and hold the mirror with the other hand Therefore, there was a problem that both hands were blocked and workability was poor. In addition, when performing the above-described operations such as makeup during night driving, the light bulb 7 is continuously turned on, and the brightly lit face and the state of the inside of the vehicle are disturbed for a long time and are placed inside the windshield. The reflected driver's seat space is extremely bright, and it is difficult for the driver to see the dark scenery outside the vehicle, and the car cannot be driven safely, and the lighting energy is lost. In addition, in the prior art, there was a sun visor with a mirror, but even if the occupant's face was brought close to the sun visor with a mirror, the illuminance could not be changed and it was always illuminated as a cosmetic mirror In addition, there is a problem in that it is inappropriate and does not prevent loss of lighting energy.

9 is an illumination device for an automobile sun visor, which comprises a sun visor 10, a support member 11 that rotatably supports the sun visor 10, and a mirror 12 mounted on the inner surface of the sun visor 10. . The vehicle sun visor lighting device 9 is installed in a vehicle cabin, particularly in the vehicle ceiling 13 near the windshield of the driver's seat and passenger seat. The sun visor 10 is fixed to the vehicle ceiling 13 via a support member 11 so as to be freely opened and closed. When the sun visor 10 is opened, that is, when it is tilted downward, as shown in FIG. 1, it hangs down from the vehicle ceiling 13 and the mirror 12 provided in the sun visor 10 faces the front of the occupant's face. Reference numeral 10a denotes a mirror cover. When the sun visor 10 is used exclusively for the sun visor, its surface is closed to cover and protect the mirror 12. Further, if the sun visor 10 is flipped up to the vehicle ceiling 12 side and stored, dust, dirt and the like are prevented from adhering and accumulating on the surface of the mirror 12.

14は照明用LEDであって、ミラー12の外周縁に複数個かつ多数個を一連に設置する。照明用LED14は例えば白色のLEDであるが、例えば女性乗員が化粧をするときに顔面を照射するので特に演色性を考慮して赤色や緑色のLEDを全体のなかに於いてその少数個を混在させることによって自然光に近い光を生成してもよい。 Reference numeral 14 denotes an illumination LED, and a plurality and a plurality of LEDs are installed in series on the outer peripheral edge of the mirror 12. The lighting LED 14 is, for example, a white LED. For example, a female occupant irradiates the face when applying makeup, so in consideration of color rendering, a small number of red and green LEDs are mixed in the whole. By doing so, light close to natural light may be generated.

15は測離センサであって、例えばサンバイザー10配置されたミラー12の近傍に設置又は内蔵している。測離センサ15は、送信部15aと受信部15bを備えておりサンバイザー10の位置と乗員の顔面位置との距離を測定して距離データを出力する。測離センサ15は測離方法やその構造の違いによる種々の測離センサを用いることができる。例えば図3に示す超音波測離センサや図4に示す赤外線LDEとPSDすなわち半導***置検出素子とを組み合わせた赤外線測離センサ等を用いることができる。測離センサ15は測離を行うための送信部15aと受信部15bを具備しており、図3に示す超音波測離センサ15Aは、送信部15aとして機能する超音波送信機器を、受信部15bとして機能する超音波受信機を有する。ここで図3に示す超音波測離センサ15Aはアース端子15c、電源端子15d及び信号端子15eを備えており、該信号端子15eは照明ユニット16の調光制御回路16Aに接続し例えば助手席に着座した乗員がサンバイザー10のミラー12のその顔面を接近し又は離遠するとき測離センサとしての超音波測離センサ15Aを動作し、この信号を調光制御回路16Aに出力する。 Reference numeral 15 denotes a separation sensor, which is installed or built in the vicinity of the mirror 12 provided with the sun visor 10, for example. The separation sensor 15 includes a transmission unit 15a and a reception unit 15b, measures the distance between the position of the sun visor 10 and the face position of the occupant, and outputs distance data. As the separation sensor 15, various separation sensors depending on a separation method or a structure thereof can be used. For example, an ultrasonic separation sensor shown in FIG. 3 or an infrared separation sensor combining an infrared LDE and PSD, that is, a semiconductor position detection element, shown in FIG. 4 can be used. The separation sensor 15 includes a transmission unit 15a and a reception unit 15b for performing separation, and the ultrasonic separation sensor 15A illustrated in FIG. 3 includes an ultrasonic transmission device that functions as the transmission unit 15a. It has an ultrasonic receiver that functions as 15b. Here, the ultrasonic separation sensor 15A shown in FIG. 3 includes a ground terminal 15c, a power supply terminal 15d, and a signal terminal 15e. The signal terminal 15e is connected to the dimming control circuit 16A of the lighting unit 16 and is installed, for example, in the passenger seat. When the seated occupant approaches or separates the face of the mirror 12 of the sun visor 10, the ultrasonic separation sensor 15A as a separation sensor is operated, and this signal is output to the dimming control circuit 16A.

次に本考案に係る自動車用サンバイザーの照明装置に於いて図2に示す照明用LEDを動作させるための電気回路に基づき本考案に係る自動車用サンバイザーの照明装置に装備した照明用LEDの照明ユニット及びその動作等を説明する。
16は照明ユニットであり例えば基盤に電子部品を組付けて構成されたユニットでなり、調光制御回路16Aと、該調光制御回路16Aの出力側に接続されたPWM信号発生回路16Bと、該PWM信号発生回路16Bの出力側に接続されたスイッチング回路16Cとで成立し、マイコンで構成される。14は前述した照明用LEDであって該照明ユニット16の出力側に接続されている。17は直流電源であり、その電圧を該照明用LED14に入力している。
Next, in the lighting device for an automotive sun visor according to the present invention, the lighting LED equipped in the lighting device for the automotive sun visor according to the present invention is based on an electric circuit for operating the lighting LED shown in FIG. The lighting unit and its operation will be described.
Reference numeral 16 denotes an illumination unit, which is a unit configured by assembling electronic components on a base, for example, a dimming control circuit 16A, a PWM signal generating circuit 16B connected to the output side of the dimming control circuit 16A, The switching circuit 16C is connected to the output side of the PWM signal generation circuit 16B, and is constituted by a microcomputer. Reference numeral 14 denotes the illumination LED described above, which is connected to the output side of the illumination unit 16. Reference numeral 17 denotes a DC power supply, and the voltage is input to the illumination LED 14.

例えば具体的にはサンバイザー10のミラー12から図3(b)に示す乗員Mの顔面fを10〜15(cm)程度近接すれば超音波測離センサ15Aの送信機15a及び受信機15bがこの近接距離を検出し該超音波測離センサ15Aは動作する。そして出力信号が照明ユニット16の調光制御回路16Aに導入される。調光制御回路16Aはデジタル電圧信号から調光制御回路16Aで設定された導通角を決定し、その導通角から予め内部メモリ(ROM)に格納された設定基準に従い、次段のPWM信号発生回路16Bが出力するPWM信号のパルス幅を決定し、調光のデューティサイクルを決める。 For example, specifically, when the face f of the occupant M shown in FIG. 3B is brought close to the mirror 12 of the sun visor 10 by about 10 to 15 (cm), the transmitter 15a and the receiver 15b of the ultrasonic separation sensor 15A are The ultrasonic distance measuring sensor 15A operates by detecting this proximity distance. Then, the output signal is introduced into the dimming control circuit 16A of the lighting unit 16. The dimming control circuit 16A determines the conduction angle set by the dimming control circuit 16A from the digital voltage signal, and the PWM signal generation circuit of the next stage is determined from the conduction angle according to the setting standard stored in the internal memory (ROM) in advance. The pulse width of the PWM signal output by 16B is determined, and the light control duty cycle is determined.

PWM信号発生回路16Bは調光制御回路16Aからの命令に従って照明用LED14に供給される電流の通電時間をパルス幅変調で制御するためのPWM信号を生成する。該PWM信号は前記導通角に対応してデューティサイクルを有するパルス信号つまり照明信号として照明用LED14に供給される電流の通電時間を制御する。これにより該照明用LED14の照度が調光の設定に応じて制御される。そしてPWM信号発生回路16Bから出力された信号はスイッチング回路16Cで照明用LED14に通電する電流のON/OFFを切り換える。かくて乗員Mの顔面fがサンバイザー10のミラー12に近接すればPWM信号発生回路16Bから出力されるPWM信号の波形が「高値」となり時間が長くなり照明用LED14の照度が高くなり乗員Mの顔面fを明るく照らすことになる。
乗員Mの顔面fがサンバイザー10のミラー12から離遠すればPWM信号発生回路16Bから出力されるPWM信号の波形が「高値」となる時間が短くなり照明用LED14の照度が低くなり乗員Mの顔面fを暗く照らし又は消灯すことになる。このようにしたので乗員の利用度に応じて照明用LED14が発光する照度を変化させ照明エネルギーの合理的活用を図ると共にドライバーの運転機能を確保できるという特徴を得た。
尚、上述した測離センサ15として超音波測離センサ15Aを採用した本願はこれに限定せず、例えば発光素子と光ICチップを樹脂モールドで一体成形した小パッケージ型近接センサでもよい。また近接センサによる人体検知時にモニタ表示消灯機能と照度センサによるバックライト調光機とを有した照度センサ機能搭載近接センサでもよい。またレンズと受光素子の小型化を図り双方の間隔を短縮したIC型小型測離センサでもよい。さらにスポット状の光の位置を検出可能とした半導***置検出素子を利用することもできる。
The PWM signal generation circuit 16B generates a PWM signal for controlling the energization time of the current supplied to the illumination LED 14 by pulse width modulation in accordance with a command from the dimming control circuit 16A. The PWM signal controls the energization time of the current supplied to the illumination LED 14 as a pulse signal having a duty cycle corresponding to the conduction angle, that is, an illumination signal. Thereby, the illuminance of the illumination LED 14 is controlled according to the dimming setting. Then, the signal output from the PWM signal generation circuit 16B switches ON / OFF of the current supplied to the illumination LED 14 by the switching circuit 16C. Thus, if the face f of the occupant M is close to the mirror 12 of the sun visor 10, the waveform of the PWM signal output from the PWM signal generation circuit 16B becomes “high value”, the time becomes longer, and the illuminance of the LED 14 for illumination becomes higher. The face f is brightly illuminated.
If the face f of the occupant M moves away from the mirror 12 of the sun visor 10, the time during which the waveform of the PWM signal output from the PWM signal generation circuit 16B becomes “high value” is shortened, and the illuminance of the LED 14 for illumination decreases and the occupant M The face f is illuminated darkly or turned off. Since it did in this way, according to the passenger | crew's utilization degree, the illumination intensity which lighted LED14 light-emitted was changed, the characteristic that the driving | operation function of a driver was ensured while aiming at rational utilization of illumination energy was acquired.
Note that the present application in which the ultrasonic separation sensor 15A is used as the separation sensor 15 described above is not limited thereto, and for example, a small package proximity sensor in which a light emitting element and an optical IC chip are integrally formed by a resin mold may be used. Further, it may be a proximity sensor equipped with an illuminance sensor function having a monitor display off function and a backlight dimmer using the illuminance sensor when a human body is detected by the proximity sensor. Further, it may be an IC type small distance measuring sensor in which the lens and the light receiving element are miniaturized to shorten the distance between them. Furthermore, a semiconductor position detecting element that can detect the position of the spot-like light can also be used.
