【０００６】 前記設定部１は、可変抵抗器１ａと固定抵抗器１ｂから成り、図１に示すＡ点 に基準電位Ｖｂ〔ボルト〕を出力する。この基準電位Ｖｂ〔ボルト〕は、可変抵 抗器１ａの操作に応じて増減する値である。 また前記発振部２は、三角波パルスを図１に示すＢ点に比較電位Ｖｒ〔ボルト 〕として導出する三角波回路２ａと、比較器２ｂから成る。該比較器２ｂは、三 角波回路２ａが導出する比較電位Ｖｒ〔ボルト〕と設定部１が導出する基準電位 Ｖｂ〔ボルト〕を入力し、その比較結果によって図１に示すＣ点に高電位信号及 び低電位信号を出力する機構を有する。例えば、図２に示す時間ｔ１〔秒〕から 時間ｔ２〔秒〕までＡ点電位値＜Ｂ点電位値であり、Ｃ点電位は低電位である。 同様に時間ｔ２〔秒〕から時間ｔ３〔秒〕までＡ点電位値＞Ｂ点電位値であり、 Ｃ点電位は高電位である。The setting unit 1 includes a variable resistor 1a and a fixed resistor 1b, and outputs a reference potential Vb [volt] to a point A shown in FIG.

【０００８】 次に上記構成から成る第１実施例の作動を図２に示すタイムチャートとともに 説明する。 先ず、設定部１よりＡ点電位を電位Ｖｂ１〔ボルト〕に設定するとき、発振部 ２の出力であるＣ点電位は、図２の（イ）部に示すごとく時間ｔ１〔秒〕から時 間ｔ２〔秒〕まで低電位、時間ｔ２〔秒〕から時間ｔ３〔秒〕まで高電位であり 、これを時間ｔ１〔秒〕から時間ｔ４〔秒〕まで繰り返し継続する。 第１出力部３は、上記Ｃ点電位を導入し、図２の（ウ）部に示すごとく時間ｔ １〔秒〕から時間ｔ２〔秒〕まで第１発振部５を消灯し、時間ｔ２〔秒〕から時 間ｔ３〔秒〕まで第１発光部５を点灯し、これを時間ｔ１〔秒〕から時間ｔ４〔 秒〕まで繰り返し継続する。第１発光部５は、この点灯時間と消灯時間の割合、 すなわち、デューティ比によって発光輝度が決まる。上記のごとくＡ点電位が比 較的高い電位Ｖｂ１〔ボルト〕であるとき、点灯時間の割合が大きく、第１発光 部５は比較的高い輝度で明るく発光することと成る。同様に、時間ｔ５〔秒〕か ら時間ｔ８〔秒〕まで、Ａ点電位が比較的低い電位Ｖｂ２〔ボルト〕であるとき 、点灯時間の割合が小さく、第１発光部５は比較的低い輝度で暗く発光すること と成る。 一方第２出力部４は、上記Ｃ点電位を導入し、図２の（エ）部に示すごとく時 間ｔ１〔秒〕から時間ｔ２〔秒〕まで第２発光部６を点灯し、時間ｔ２〔秒〕か ら時間ｔ３〔秒〕まで第２発光部を消灯し、これを時間ｔ１〔秒〕から時間ｔ４ 〔秒〕まで繰り返し継続する。第２発振部６は、上記第１発光部５と同様にこの 点灯時間と消灯時間の割合、すなわちデューティ比によって発光輝度が決まる。 上記のごとくＡ点電位が比較的高い電位Ｖｂ１〔ボルト〕であるとき、点灯時間 の割合が小さく、第２発光部６は比較的低い輝度で暗く発光することと成る。同 様に、第２発光部６は時間ｔ５〔秒〕から時間ｔ８〔秒〕まで明るく発光する。 この様に、第１発光部５及び第２発光部６は、設定部１による基準電位Ｖｂ〔 ボルト〕の値に応じて一方が明るく点灯すれば他方が相反して暗く点灯する。第 １発光部５及び第２発光部６は、それぞれ異った波長のスペクトル光線を発して 点灯するので、上記作用により基準電位Ｖｂ〔ボルト〕の値に応じて色調が変化 する。Next, the operation of the first embodiment having the above configuration will be described with reference to the time chart shown in FIG. First, when the potential of the point A is set to the potential Vb1 [volt] by the setting unit 1, the potential of the point C, which is the output of the oscillating unit 2, is changed from the time t1 [second] to the time as shown in part (a) of FIG. The electric potential is low from t2 [seconds] and high from time t2 [seconds] to time t3 [seconds], and this is repeated continuously from time t1 [seconds] to time t4 [seconds]. The first output unit 3 introduces the potential at the point C, turns off the first oscillating unit 5 from the time t 1 [sec] to the time t2 [sec], as shown in FIG. From the second] to the time t3 [second], the first light emitting unit 5 is turned on, and this is repeated continuously from the time t1 [second] to the time t4 [second]. The light emission brightness of the first light emitting unit 5 is determined by the ratio of the lighting time and the extinction time, that is, the duty ratio. As described above, when the potential at the point A is a relatively high potential Vb1 [volt], the proportion of the lighting time is large, and the first light emitting section 5 emits bright light with relatively high brightness. Similarly, from the time t5 [seconds] to the time t8 [seconds], when the point A potential is the relatively low potential Vb2 [volt], the proportion of the lighting time is small, and the first light emitting unit 5 has a relatively low brightness. It emits light in the dark. On the other hand, the second output section 4 introduces the potential at the point C, lights the second light emitting section 6 from the time t1 [seconds] to the time t2 [seconds], as shown in FIG. The second light emitting unit is turned off from [sec] to time t3 [sec], and this is repeated from time t1 [sec] to time t4 [sec]. Similar to the first light emitting unit 5, the second oscillating unit 6 determines the light emission brightness by the ratio of the lighting time and the extinction time, that is, the duty ratio. As described above, when the potential at the point A is a relatively high potential Vb1 [volt], the proportion of the lighting time is small, and the second light emitting section 6 emits dark light with relatively low brightness. Similarly, the second light emitting unit 6 emits bright light from time t5 [seconds] to time t8 [seconds]. As described above, according to the value of the reference potential Vb [volt] set by the setting unit 1, one of the first light emitting unit 5 and the second light emitting unit 6 lights up brightly while the other lights up contradictoryly. Since the first light emitting section 5 and the second light emitting section 6 emit spectral light rays having different wavelengths and are lit, the color tone changes according to the value of the reference potential Vb [volt] due to the above action.

【第２実施例】 図３は、この考案に係る第２実施例を示した電気回路図である。 同図に於いて、設定部８が前記した第１実施例と相違し、他の構成は説明を省 略する。 設定部８は、所定の物理量例えば、温度値〔℃〕に応じたレベルの基準電位Ｖ ｒ〔ボルト〕を出力するものである。 該設定部８は、温度に応じて抵抗値が変化する、例えば低温で抵抗値が高く、 高温で抵抗値が低く成るサーミスタ８ａと、抵抗８ｂ及び８ｃとで接続構成して いる。Second Embodiment FIG. 3 is an electric circuit diagram showing a second embodiment according to the present invention. In the figure, the setting unit 8 is different from that of the first embodiment described above, and the description of other configurations is omitted. The setting unit 8 outputs a reference potential V r [volt] having a level corresponding to a predetermined physical quantity, for example, a temperature value [° C.]. The setting unit 8 is composed of a thermistor 8a whose resistance value changes according to temperature, for example, a resistance value is high at low temperature and low at high temperature, and resistors 8b and 8c.
【００１０】 次に、上記第２実施例の作動を説明する。 設定部８以外の各構成による作動は、第１実施例と同じである。設定部８がＡ 点に導出する基準電位Ｖｂ〔ボルト〕は、検知温度が低いとき比較的高い電位Ｖ ｂ１〔ボルト〕と成り、逆に検知温度が高いとき比較的低い電位Ｖｂ２〔ボルト 〕と成る。そのため、設定部８による検知温度が低いとき、赤色系のスペクトル 光線を発する第１発光部５は明るく発光し、青色系のスペクトル光線を発する第 ２発光部６は暗く発光する。逆に設定部８による検知温度が高いとき、第１発光 部５は暗く、第２発光部６は明るく発光する。 この様に、第１発光部５及び第２発光部６は、設定部８による検知温度が低い ときに暖色である赤色系の色調で発光し、検知温度が高いときに寒色である青色 系の色調で発光する。 上記第１発光部５及び第２発光部６を、例えば車両の計器盤や室内灯に使用す れば、冬の寒い季節に暖色の照明を行ない、夏の暑い季節に寒色の照明を行なう ことができ、色調の変化によってドライバー等乗員の快適さを実現することがで きる。Next, the operation of the second embodiment will be described. The operation of each configuration other than the setting unit 8 is the same as that of the first embodiment. The reference potential Vb [volt] that the setting unit 8 derives at the point A is a relatively high potential Vb1 [volt] when the detected temperature is low, and conversely is a relatively low potential Vb2 [volt] when the detected temperature is high. Become. Therefore, when the temperature detected by the setting unit 8 is low, the first light emitting unit 5 which emits the red spectrum light beam emits light brightly, and the second light emitting unit 6 which emits the blue spectrum light beam emits darkly. Conversely, when the temperature detected by the setting unit 8 is high, the first light emitting unit 5 emits dark light and the second light emitting unit 6 emits bright light. In this way, the first light emitting unit 5 and the second light emitting unit 6 emit light in a reddish color tone that is a warm color when the temperature detected by the setting unit 8 is low, and emit a cold blue color when the detection temperature is high. It emits light in color. If the first light emitting unit 5 and the second light emitting unit 6 are used for, for example, an instrument panel or an interior light of a vehicle, a warm color illumination is performed in the cold winter season and a cold illumination is performed in the hot summer season. It is possible to achieve comfort for the driver and other passengers by changing the color tone.

Further, since the second light emitting unit is turned off when the first light emitting unit is turned on and the second light emitting unit is turned on when the first light emitting unit is turned off, the first light emitting unit and the second light emitting unit are used. The overall brightness can be made almost uniform. Further, if the setting unit is configured to output a reference potential having a level according to a predetermined physical quantity such as temperature, the first light emitting unit and the second light emitting unit are controlled so as to emit a light beam having a color tone according to the physical quantity. be able to.
