Description

本発明は、焦電型赤外線センサー(人体センサー)により制御される照明器具に関する。   The present invention relates to a lighting apparatus controlled by a pyroelectric infrared sensor (human body sensor).

本体の下面にランプと焦電型赤外線センサーを設けて前記センサーのみを露出する窓孔のある半透光性のグローブで覆い、前記センサーにより人体が検知された場合に前記ランプを点灯する照明器具はよく知られたところである。そして、焦電型赤外線センサーでは電源投入直後から約10〜20秒間程度は動作が不安定なため、そのセンサーからの出力状態を無視して、電源投入直後の所定時間に渡ってランプを強制的に全光点灯モードとしてユーザーに不審感を与えないようにするとともに、この時間を前記センサーのための安定化待機時間としている。そして、この全光点灯モード終了後は人体検知のない限り前記ランプを消灯させていた。ところで、特許文献１のように、本体の下面にランプと焦電型赤外線センサーを設けた上で前記のような窓孔のない半透光性のグローブで覆う照明器具も知られている。
特開平１０−１０６３４０号公報 A luminaire provided with a lamp and a pyroelectric infrared sensor on the lower surface of the main body, covered with a semi-transparent glove having a window hole exposing only the sensor, and lighting the lamp when a human body is detected by the sensor Is well known. The pyroelectric infrared sensor is unstable for about 10 to 20 seconds immediately after the power is turned on, so the output from the sensor is ignored and the lamp is forced for a predetermined time immediately after the power is turned on. In the all-light lighting mode, the user is not suspicious and this time is set as a stabilization waiting time for the sensor. After the all-light lighting mode is completed, the lamp is turned off unless a human body is detected. Incidentally, as in Patent Document 1, there is also known a lighting fixture in which a lamp and a pyroelectric infrared sensor are provided on the lower surface of a main body and covered with a semi-transparent glove having no window hole as described above.
JP-A-10-106340

しかし、特許文献１のような照明器具において、電源投入直後の強制的全光点灯モードの終了後にランプが消灯すると、次のような問題が発生することが分かってきた。すなわち、人体が検知されていないにもかかわらず、一旦消灯したランプが再び点灯する問題である。この原因について究明して行くと、最近の照明器具は小型化または薄型化される傾向にあるにもかかわらず、ランプは逆に比較的高ワットのものが用いられるようになっており、ランプからわずかに放出される長波長域(人体からの赤外線と同様な10μｍ前後の長波長域)の赤外線が前記センサーに入射して検知されており、前記センサーは入射する赤外線量の変化に反応するタイプのため、ランプがいきなり消灯になると人体を検知したときと同様に検知信号を発生してしまい、ランプが点灯するということであった。このように、焦電型赤外線センサーをグローブ内に収めた照明器具においては、ランプからの赤外光がグローブ内面で反射して前記センサーに入射するため、このような問題(自己点滅誤動作)が発生しやすくなっているのが判明した。本発明はこのような解決すべき課題を鑑み、焦電型赤外線センサー(人体センサー)により制御される照明器具における自己点滅誤動作を防止することを目的とする。   However, it has been found that the following problems occur when the lamp is turned off after the forced all-light lighting mode ends immediately after the power is turned on in the lighting fixture as in Patent Document 1. That is, there is a problem that a lamp once turned off is turned on again even though a human body is not detected. When investigating this cause, even though recent lighting fixtures tend to be smaller or thinner, lamps with relatively high wattage are used instead. Slightly emitted long-wavelength range (long wavelength range around 10μm, similar to the infrared rays from the human body) is detected by being incident on the sensor, and the sensor responds to changes in the amount of incident infrared rays. Therefore, when the lamp suddenly turns off, a detection signal is generated in the same manner as when a human body is detected, and the lamp is turned on. In this way, in the lighting fixture in which the pyroelectric infrared sensor is housed in the globe, the infrared light from the lamp is reflected by the inner surface of the globe and enters the sensor. It turns out that it is easy to occur. In view of such problems to be solved, an object of the present invention is to prevent a self-flashing malfunction in a lighting fixture controlled by a pyroelectric infrared sensor (human body sensor).

本発明を要約すると、本体の下面にランプと焦電型赤外線センサーを設けて半透光性のグローブで覆い、前記センサーにより人体が検知された場合に前記ランプを点灯する照明器具において、電源投入直後の所定時間に渡ってランプを強制的に全光点灯モードとし、この全光点灯モード終了後、ランプを比較的短時間に渡る調光点灯モードを経て消灯させる機能を備えた照明器具である。   To summarize the present invention, a lamp and a pyroelectric infrared sensor are provided on the lower surface of the main body and covered with a semi-transparent glove, and the lighting is turned on when a human body is detected by the sensor. It is a lighting fixture having a function of forcibly setting the lamp to the all-light lighting mode for a predetermined time immediately after it, and turning off the lamp through the dimming lighting mode for a relatively short time after the end of the all-light lighting mode. .

本発明によれば、電源投入直後の強制的な全光点灯モード終了後、ランプは調光点灯モードになるため、ランプからの光出力変化比が緩和されるため、焦電型赤外線センサーに入射する光変化比も小さくなり、前記センサーからは検知信号が出力されないため、従来のようにランプが再び全光点灯するような自己点滅誤動作が防止される。また、調光点灯モードから消灯になる際のランプの光出力変化比も少なくなり、やはり、自己点滅誤動作が防止される。   According to the present invention, after the forced all-light lighting mode ends immediately after the power is turned on, the lamp enters the dimming lighting mode, so that the light output change ratio from the lamp is relaxed, so that it enters the pyroelectric infrared sensor. Since the light change ratio is also reduced and no detection signal is output from the sensor, a self-flashing malfunction that causes the lamp to light all the light again as in the prior art is prevented. Further, the light output change ratio of the lamp when turning off from the dimming lighting mode is also reduced, and the self-flashing malfunction is also prevented.

次に、本発明の実施形態を説明するが、それはあくまで本発明に基づいて採択された例示的な実施形態であり、本発明をその実施形態に特有な事項に基づいて限定解釈してはならず、本発明の技術的範囲は、特許請求の範囲の請求項に示した事項さらにはその事項と実質的に等価である事項に基づいて定めなければならない。   Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention should not be limitedly interpreted based on matters specific to the embodiment. The technical scope of the present invention should be determined based on the matters shown in the claims of the claims and matters substantially equivalent to the matters.

図示の実施形態は、本体１の下面に蛍光ランプまたは白熱ランプなどのランプ２と焦電型赤外線センサー３を設けて半透光性のグローブ４(人体からの赤外線を通すポリエチレン製など)で覆い、前記センサー３により人体が検知された場合に前記ランプ２を点灯する照明器具において、電源投入直後の所定時間(例えば30秒間)に渡ってランプ２を強制的に全光点灯モードとし、この全光点灯モード終了後、ランプ２を比較的短時間に渡る調光点灯モードを経て消灯させる機能を備えた照明器具である。なお、前記所定時間としては最低限20秒程度あればよく、上限としては、点灯継続し過ぎてユーザーに不審感を持たれないように60秒程度とすればよい。   In the illustrated embodiment, a lamp 2 such as a fluorescent lamp or an incandescent lamp and a pyroelectric infrared sensor 3 are provided on the lower surface of the main body 1 and covered with a semi-transparent glove 4 (such as polyethylene that transmits infrared rays from the human body). When the human body is detected by the sensor 3, in the lighting fixture that lights the lamp 2, the lamp 2 is forcibly set to the all-light lighting mode for a predetermined time (for example, 30 seconds) immediately after the power is turned on. It is a lighting fixture having a function of turning off the lamp 2 through a dimming lighting mode over a relatively short time after the light lighting mode ends. The predetermined time may be at least about 20 seconds, and the upper limit may be about 60 seconds so that the user does not feel suspicious because the lighting continues for a long time.

さらに詳述すれば、本実施形態ではランプ２は二重環型40Ｗのように高輝度タイプの環状蛍光ランプであり、その略中央にセンサー３を配置している。また、強制的な全光点灯モードから調光点灯モードへの光出力変化比を40〜70％とし、かつ、調光点灯モードの時間を１〜５秒としている。前記センサー３の検知信号はマイコン５に入力され、マイコン５は検知信号に応じてインバータ制御部６に点灯信号、調光切替信号を供給する。インバータ制御部６はインバータ７の半導体スイッチング素子８、８を交互に開閉するためのインバータ駆動信号を供給し、これにより直流電源９が高周波交流に変換されてコイル・コンデンサなどの限流素子１０を介してランプ２に供給される。   More specifically, in the present embodiment, the lamp 2 is a high-luminance type annular fluorescent lamp such as a double ring type 40W, and the sensor 3 is disposed at the approximate center thereof. Further, the light output change ratio from the forced all-light lighting mode to the dimming lighting mode is 40 to 70%, and the time of the dimming lighting mode is 1 to 5 seconds. The detection signal of the sensor 3 is input to the microcomputer 5, and the microcomputer 5 supplies a lighting signal and a dimming switching signal to the inverter control unit 6 in accordance with the detection signal. The inverter control unit 6 supplies an inverter drive signal for alternately opening and closing the semiconductor switching elements 8 and 8 of the inverter 7, whereby the DC power source 9 is converted into a high-frequency AC, and the current limiting element 10 such as a coil and a capacitor To be supplied to the lamp 2.

動作を説明すると、まず、電源が時刻t0にて投入されると、マイコン５は強制的に点灯信号(Ｌレベル)をインバータ制御部６に出力するのでインバータ制御部６はインバータ７を全出力動作させて、ランプ２は強制点灯する。このとき調光切替信号はＨレベルのため、ランプ２は全光点灯(定格点灯)する。この目的は前述したように、焦電型赤外線センサー３は電源投入直後から約10〜20秒間程度は動作が不安定なため、そのセンサー３からの出力状態(検知信号)を無視して、電源投入直後の所定時間に渡ってランプ２を強制的に全光点灯モードとするものであり、この時間を前記センサー３のための安定化待機時間としている。この時間が経過した後、本実施形態の特徴として、t1〜t2(１〜５秒間)においても点灯信号(Ｌレベル)を継続させるとともに、調光切替信号をＬレベルにしてランプ２を調光点灯モードとする。このように電源投入直後の強制的な全光点灯モード終了後、ランプ２は調光点灯モードになるため、ランプ２からの光出力変化比が緩和されるため、センサー３に入射する光変化比も小さくなり、センサー３からは検知信号が出力されないため、従来のようにランプ２が再び全光点灯するような自己点滅誤動作が防止される。また、時刻t2にて調光点灯モードから消灯になるが、調光点灯モードから消灯になる際のランプ２の光出力変化比も少なくなり、やはり、自己点滅誤動作が防止される。次に、時刻t3にて本照明器具に人体が近づいてきてセンサー３により人体検知されると、センサー３からの検知信号でマイコン５は点灯信号を出力してランプ２を全光点灯する。次に、時刻t4にて人体検知が無くなるとマイコン５は点灯信号は継続しつつ調光切替信号(Ｌレベル)を発生してランプ２を調光点灯してから、時刻t5にてランプ２を消灯する。   The operation will be described. First, when the power is turned on at time t0, the microcomputer 5 forcibly outputs a lighting signal (L level) to the inverter control unit 6, so that the inverter control unit 6 operates the inverter 7 at all outputs. Then, the lamp 2 is forcibly lit. At this time, since the dimming switching signal is at the H level, the lamp 2 is lit in all light (rated lighting). As described above, the purpose of the pyroelectric infrared sensor 3 is unstable for about 10 to 20 seconds immediately after the power is turned on. Therefore, the output state (detection signal) from the sensor 3 is ignored and the power supply is ignored. The lamp 2 is forcibly set to the all-light lighting mode for a predetermined time immediately after being turned on, and this time is set as a stabilization waiting time for the sensor 3. After this time has elapsed, as a feature of this embodiment, the lighting signal (L level) is continued during t1 to t2 (1 to 5 seconds), and the dimming switching signal is set to L level to dimm the lamp 2. Set to lighting mode. Since the lamp 2 is in the dimming lighting mode after the forced all-light lighting mode immediately after the power is turned on in this way, the light output change ratio from the lamp 2 is relaxed, so that the light change ratio incident on the sensor 3 is reduced. Since the sensor 3 does not output a detection signal, a self-flashing malfunction that causes the lamp 2 to light all the light again as in the prior art is prevented. Further, although the dimming lighting mode is turned off at the time t2, the light output change ratio of the lamp 2 when the dimming lighting mode is turned off is also reduced, and the self-flashing malfunction is also prevented. Next, when the human body approaches the lighting fixture at time t3 and the human body is detected by the sensor 3, the microcomputer 5 outputs a lighting signal by the detection signal from the sensor 3 to turn on the lamp 2 all light. Next, when there is no human body detection at time t4, the microcomputer 5 generates a dimming switching signal (L level) while continuing the lighting signal to dim the lamp 2, and then turns on the lamp 2 at time t5. Turns off.

本実施形態によれば、電源投入直後の強制的な全光点灯モード終了後、ランプ２は調光点灯モードになるため、ランプ２からの光出力変化比が緩和されるため、焦電型赤外線センサー３に入射する光変化比も小さくなり、前記センサー３からは検知信号が出力されないため、従来のようにランプ２が再び全光点灯するような自己点滅誤動作が防止される。また、調光点灯モードから消灯になる際のランプ２の光出力変化比も少なくなり、やはり、自己点滅誤動作が防止される。   According to the present embodiment, since the lamp 2 enters the dimming lighting mode after the forced all-light lighting mode immediately after the power is turned on, the light output change ratio from the lamp 2 is relaxed. The ratio of change in the light incident on the sensor 3 is also reduced, and no detection signal is output from the sensor 3, so that a self-flashing malfunction that causes the lamp 2 to light all the light again as in the prior art is prevented. Further, the light output change ratio of the lamp 2 when the light is turned off from the dimming lighting mode is reduced, and the self-flashing malfunction is also prevented.
