図３のフローチャートは自動調光を行う前の調光の設定値設定ならびに自動調光開始を示す。
The remote control transmitter 2 (not shown) is provided with a “light button” for the main light, an “light-off button”, an “automatic light control button”, and an “up button” and a “down button” for the brightness of the main light. ing.
(Description of operation)
The operation of automatic light control will be described based on the flowcharts of FIGS.
The flowchart of FIG. 3 shows the setting value setting of light control and the start of automatic light control before performing automatic light control.
以下の手順により調光値の設定を行う。
(1) リモコン送信機を使用し、希望の調光状態に設定する。
(2) リモコン送信機の「自動調光ボタン」を所定時間（例えば約３秒）押し続ける。
(3) 制御部は照度センサの出力値を読み出し、自動調光する照度に設定（設定値ａ）する。本設定は制御部の不揮発メモリに記憶する。設定時にはブザーを通常の受付時より鳴動回数を増やして報知する。
(4) モードを自動調光モードにする。
上記設定を実施した場合には、設定値が不揮発メモリに記録されているため次回以降の設定は不要であり、「自動調光」ボタンの押下のみでモードを自動調光モードにする。
The dimming value is set according to the following procedure.
(1) Use the remote control transmitter to set the desired dimming condition.
(2) Press and hold the “automatic light control button” on the remote control transmitter for a predetermined time (eg, about 3 seconds).
(3) The control unit reads the output value of the illuminance sensor and sets the illuminance to be automatically adjusted (set value a). This setting is stored in the nonvolatile memory of the control unit. At the time of setting, the buzzer is notified by increasing the number of rings compared to the normal reception.
(4) Set the mode to automatic dimming mode.
When the above setting is performed, the setting value is recorded in the non-volatile memory, so the setting after the next time is unnecessary, and the mode is set to the automatic dimming mode only by pressing the “auto dimming” button.
図４のフローチャートは自動調光モードの動作を示す。 The flowchart of FIG. 4 shows the operation in the automatic light control mode.
自動調光モードの動作は以下の通りである。 The operation in the automatic dimming mode is as follows.
照度センサ３０により所定時間Ｔ４の間隔で照度を取り込む（取り込み値ｂ）。 取り込み値ｂと設定値ａを比較して、次のように点灯状態を調整する。
（１）ａ＞ｂのときは、設定値より明るすぎるので、照明の出力を下げる。
（２）ａ＜ｂのときは、暗すぎるので、照明の出力を上げる。
（３）ａ＝ｂのときは、設定通りなので、照明の出力を変化させない。
以上の動作を繰り返す。繰り返しの時間は以下に示す方法で決定する。
Illuminance is captured by the illuminance sensor 30 at intervals of a predetermined time T4 (capture value b). The captured value b is compared with the set value a and the lighting state is adjusted as follows.
(1) When a> b, the output of the illumination is lowered because it is too bright than the set value.
(2) When a <b, it is too dark, so increase the output of illumination.
(3) When a = b, it is as set, so the illumination output is not changed.
The above operation is repeated. The repetition time is determined by the following method.
点灯状態の調整の周期は取り込み値ｂと設定値ａを比較して、取り込み値ｂと設定値ａの差分の絶対値が規定値ｃよりも大きい場合、次回の調整の周期ＴをＴ１とし、小さい場合は次回の調整の周期ＴをＴ２とする。このときＴ１＜Ｔ２とする。 The adjustment period of the lighting state is a comparison between the captured value b and the set value a. If the absolute value of the difference between the captured value b and the set value a is greater than the specified value c, the period T of the next adjustment is T1; If it is smaller, the next adjustment cycle T is set to T2. At this time, T1 <T2.
上記の通りの動作により、目標とする照度(設定値ａ)に対し取り込み値ｂが大きく離れている場合にはすばやく目標に到達し、設定値ａと取り込み値ｂが近い場合にはゆっくりと制御を行い、明るさの急峻な変化を無くすことができる。 By the operation as described above, when the captured value b is far away from the target illuminance (set value a), the target is reached quickly, and when the set value a and the captured value b are close, the control is performed slowly. And a sharp change in brightness can be eliminated.
なお本実施形態では照明の出力を変化させない場合はａ＝ｂとしているが、変化させない範囲を設定値ｂにヒステリシス値ｄを加算したものとしてもよいし、設定値より大きい場合のヒステリシス値小さい場合のヒステリシス値を変えてもよい。 In the present embodiment, a = b is set when the illumination output is not changed, but the range not changed may be obtained by adding the hysteresis value d to the set value b, or when the hysteresis value is smaller than the set value. The hysteresis value may be changed.
図５のフローチャートに基づいて、自動調光の目標の変更動作を説明する。 Based on the flowchart of FIG. 5, the operation for changing the target of automatic light control will be described.
使用者は希望の調光状態となるように予め前記の手段によって目標値の設定を行っているが、目標となった調光状態に到達したときの明るさが希望よりも、明るかったり暗かったりする場合が考えられる。その際にはもう一度明るさを変更し前記の「(2)リモコン送信機２の「自動調光」ボタンを所定時間（例えば約３秒）押し続ける。」操作を行う必要がある。 The user sets the target value in advance using the above means so that the desired dimming state is achieved, but the brightness when the target dimming state is reached may be brighter or darker than desired. If you want to. At that time, the brightness is changed once again, and the "(2)" automatic light control "button of the remote control transmitter 2 is kept pressed for a predetermined time (for example, about 3 seconds). Need to do the operation.
そこで、「自動調光」動作を行っている場合にリモコン送信機２における主灯の明るさの「アップボタン」および「ダウンボタン」を押下された場合には、主灯の明るさをアップまたはダウンすると同時に設定値も予め規定された値分アップまたはダウンする。それにより顧客は操作が受け付けられたとわかり、同時に設定値の微調整が可能となる。
Therefore, when the “up button” and “down button” of the brightness of the main lamp in the remote control transmitter 2 are pressed while performing the “automatic light control” operation, the brightness of the main lamp is increased or Simultaneously with the down, the set value is increased or decreased by a predetermined value. Thereby, the customer knows that the operation has been accepted, and at the same time, the setting value can be finely adjusted.
