Description

本発明は、浴室等に取り付けられた白熱灯を調光するための調光装置に関する。   The present invention relates to a dimming device for dimming an incandescent lamp attached to a bathroom or the like.

従来、浴室等に取り付けられた白熱灯を調光するための調光装置は、調光操作するための押しボタンスイッチの個数を少なくするために、押しボタンスイッチを押操作する時間の長さに応じて段階調光か無段階調光かを選択するように構成されたものがある。この調光装置によれば、押しボタンスイッチを押操作する時間が短くて段階調光が選択された場合、押しボタンスイッチの1回の押操作で段階調光率レベルを1段階変化させるように制御される(特許文献1参照)。
特開2002−329586号公報(〔0005〕欄)
Conventionally, a dimming device for dimming an incandescent lamp installed in a bathroom or the like has a length of time to push and operate the push button switch in order to reduce the number of push button switches for dimming operation. Some are configured to select step dimming or stepless dimming accordingly. According to the light control device, when the time for pressing the push button switch is short and the step light control is selected, the step light control rate level is changed by one step by one press operation of the push button switch. It is controlled (see Patent Document 1).
JP 2002-329586 A (column [0005])

上記従来の調光装置によれば、段階調光が選択された場合、現在の調光率に関わらず、現在の調光率に一番近い段階調光率レベルに調光制御される。即ち、現在の調光率が例えば51パーセントである場合、白熱灯を減光操作する押しボタンスイッチを押操作すると、50パーセントの段階調光率レベルに調光制御される。これにより、白熱灯を減光操作する押しボタンスイッチを押操作しても調光率が1パーセントしか変化しないため、調光する人は調光率の変化、即ち、白熱灯の明るさの変化を認識することができない。   According to the conventional dimming device, when step dimming is selected, dimming control is performed to the step dimming rate level closest to the current dimming rate regardless of the current dimming rate. That is, when the current dimming rate is 51%, for example, when the push button switch for dimming the incandescent lamp is pressed, the dimming control is performed to a step dimming level of 50%. As a result, even if the push button switch for dimming the incandescent lamp is pushed, the dimming rate only changes by 1%. Cannot be recognized.

そこで本発明では、段階調光に際して、現在の調光率に関わらず、調光する人が白熱灯の明るさの変化を認識することができる調光装置を提供することを解決すべき課題とするものである。   Therefore, in the present invention, it is a problem to be solved to provide a light control device capable of recognizing a change in brightness of an incandescent lamp regardless of the current light control rate in the step light control. To do.

上記課題は、特許請求の範囲の欄に記載した調光装置により解決することができる。
請求項1及び請求項2に記載の調光装置は、段階調光制御を行なう際、現在の調光率と調光する方向で一番近い段階調光率レベルとの差が、予め決められた設定調光率差以上の場合は一番近い段階調光率レベルに調光する一方、設定調光率差未満の場合は一段階飛ばした段階調光率レベルに調光する。これにより、調光する人は、現在の調光率に関わらず、白熱灯の明るさの変化を認識することができる。
The above problems can be solved by the light control device described in the appended claims.
In the dimming device according to claim 1 or 2, when performing step dimming control, the difference between the current dimming rate and the closest step dimming level in the dimming direction is determined in advance. When the difference is greater than or equal to the set dimming rate difference, the light is dimmed to the nearest step dimming rate level, whereas when the difference is less than the set dimming rate difference, the dimming level is dimmed by one step. Thereby, the person who adjusts light can recognize the change of the brightness of the incandescent lamp regardless of the current dimming rate.

本発明によれば、段階調光に際して、現在の調光率に関わらず、調光する人は、白熱灯の明るさの変化を認識することができるという効果がある。   According to the present invention, there is an effect that a person who performs dimming can recognize a change in the brightness of the incandescent lamp regardless of the current dimming rate.

FIG. 3 is a control system diagram showing an electrical configuration of the light control device 1.
In FIG. 3, the incandescent lamps 2a and 2b are attached to the bathroom as described above, and the dimming switch 5 is attached to the wall surface of the bathroom as described above. Further, the microcomputer 7 and the dimming circuit 8 are built in the dimming lighting control box 4 described above. The dimming illumination control box 4 is provided with a power supply circuit 9 for supplying a necessary power supply voltage to the microcomputer 7 and the dimming circuit 8.

上記マイクロコンピュータ7は、調光スイッチ5のスイッチ5a,5bが押操作された場合の操作信号を入力し、それぞれの操作時間に応じて段階調光制御もしくは無段階調光制御を行なうためのソフトウエアを有している。また、マイクロコンピュータ7は、調光スイッチ5に設けられている調光レベル表示器5cに対して、現在の調光率レベルを表示させる表示信号を出力するためのソフトウエアを有している。
尚、マイクロコンピュータ7による段階調光制御及び無段階調光制御については後で詳しく説明する。
The microcomputer 7 receives an operation signal when the switches 5a and 5b of the dimming switch 5 are pressed, and software for performing step dimming control or stepless dimming control according to each operation time. Have wear. Further, the microcomputer 7 has software for outputting a display signal for displaying the current dimming rate level to the dimming level indicator 5 c provided in the dimming switch 5.
The step dimming control and the stepless dimming control by the microcomputer 7 will be described in detail later.

上記調光回路8は、マイクロコンピュータ7から出力された調光制御信号に基づいてAC100V電圧の位相制御を行なうことにより、白熱灯2a,2bに印加される電圧を調整し、調光率を変化させるように構成されている。   The dimming circuit 8 adjusts the voltage applied to the incandescent lamps 2a and 2b by changing the phase of the AC 100V voltage based on the dimming control signal output from the microcomputer 7, and changes the dimming rate. It is configured to let you.

次に、調光装置1の調光制御について説明する。図4は、調光装置1の基本的な調光制御作用を示したタイミングチャートである。
図4において、タイミングチャート(A)は、調光スイッチ5のスイッチ5b(調光率ダウン用)の操作タイミングチャート、タイミングチャート(B)は、調光スイッチ5のスイッチ5a(調光率アップ用)の操作タイミングチャート、タイミングチャート(C)は、スイッチ5b,5aの操作時間に対応したマイクロコンピュータ7による調光制御タイミングチャートである。尚、この場合、段階調光制御の段階調光率レベルは、100パーセント、62パーセント、及び25パーセントの3段階としている。
Next, dimming control of the dimming device 1 will be described. FIG. 4 is a timing chart showing the basic dimming control action of the dimming device 1.
4, a timing chart (A) is an operation timing chart of the switch 5b (for dimming rate reduction) of the dimming switch 5, and a timing chart (B) is a switch 5a (for dimming rate increase) of the dimming switch 5. ) Operation timing chart and timing chart (C) are dimming control timing charts by the microcomputer 7 corresponding to the operation times of the switches 5b and 5a. In this case, the step dimming rate level of the step dimming control is set to three steps of 100%, 62%, and 25%.

図4において、浴室使用者が、前記白熱灯2a,2bの調光率を100パーセントからダウンさせるためにスイッチ5bをオンし、そのオン操作が0.5秒を超えると、マイクロコンピュータ7は調光率を20%/秒のレートで無段階にダウンさせる。調光率がXパーセントまでダウンしたとき、浴室使用者はスイッチ5bをオフしている。そのあと、スイッチ5bが0.5秒未満の間、オンされると、マイクロコンピュータ7は段階調光制御を選択し、25パーセントの調光率までダウンさせる。   In FIG. 4, when the bathroom user turns on the switch 5b in order to lower the dimming rate of the incandescent lamps 2a and 2b from 100%, and the on operation exceeds 0.5 seconds, the microcomputer 7 is adjusted. The light rate is decreased steplessly at a rate of 20% / second. When the dimming rate is reduced to X percent, the bathroom user turns off the switch 5b. After that, when the switch 5b is turned on for less than 0.5 seconds, the microcomputer 7 selects the step dimming control and lowers the dimming rate to 25%.

調光率が25パーセントまでダウンされた状態で、浴室使用者が白熱灯2a,2bの調光率をアップさせるためにスイッチ5aを0.5秒以上、オンすると、マイクロコンピュータ7は調光率を20%/秒のレートで無段階にアップさせる。調光率がZパーセントまでアップしたとき、浴室使用者はスイッチ5aをオフしている。そのあと、スイッチ5aが0.5秒未満の間、オンされると、マイクロコンピュータ7は段階調光制御を選択し、調光率を段階的にアップさせる。   If the bathroom user turns on the switch 5a for 0.5 seconds or more in order to increase the dimming rate of the incandescent lamps 2a and 2b with the dimming rate lowered to 25%, the microcomputer 7 turns on the dimming rate. Is steplessly increased at a rate of 20% / second. When the dimming rate is increased to Z percent, the bathroom user turns off the switch 5a. Thereafter, when the switch 5a is turned on for less than 0.5 seconds, the microcomputer 7 selects the step dimming control and increases the dimming rate step by step.

次に、調光装置1の調光制御の特徴を、図5を参照して具体的に説明する。
図5は、前記調光スイッチ5の調光率ダウン用スイッチ5b、もしくは調光率アップ用スイッチ5aのオン時間が0.5秒未満であるため、マイクロコンピュータ7が段階調光制御を選択した場合の作用説明図である。尚、この段階調光制御では、段階調光率レベルを、100パーセント、75パーセント、50パーセント、及び25パーセントの4段階としている。また、ギリシャ文字αは、特許請求の範囲の欄に記載した設定調光率差を示す。尚、設定調光率差を3〜10パーセントの範囲に設定するが、この場合、設定調光率差を5パーセントとする。
Next, the features of the dimming control of the dimming device 1 will be specifically described with reference to FIG.
FIG. 5 shows that the microcomputer 7 selects the step dimming control because the ON time of the dimming rate down switch 5b or the dimming rate up switch 5a of the dimming switch 5 is less than 0.5 seconds. FIG. In this step dimming control, the step dimming rate level is set to four steps of 100%, 75%, 50%, and 25%. The Greek letter α indicates the set dimming rate difference described in the claims. The set dimming rate difference is set in the range of 3 to 10%. In this case, the set dimming rate difference is set to 5%.

浴室使用者が前記白熱灯2a,2bを減光させるために調光スイッチ5の調光率ダウン用スイッチ5bを0.5秒未満オンすると、マイクロコンピュータ7は段階調光制御を選択する。図5に示すように、現在の調光率PLが52パーセントである場合、調光率ダウン方向での一番近い段階調光率レベルは50パーセントであるため、現在の調光率PLとの差は2パーセントである。しかるに設定調光率差は5パーセントに設定されているため、マイクロコンピュータ7は、調光率ダウン方向での一番近い段階調光率レベルの50パーセントを飛ばして段階調光率レベル25パーセントまで調光率を下げる。これにより、浴室使用者は、白熱灯が明らかに調光されたことを認識することができる。   When the bathroom user turns on the dimming rate down switch 5b of the dimming switch 5 for less than 0.5 seconds to dimm the incandescent lamps 2a and 2b, the microcomputer 7 selects the step dimming control. As shown in FIG. 5, when the current dimming rate PL is 52%, the closest step dimming level in the dimming rate down direction is 50%. The difference is 2 percent. However, since the set dimming rate difference is set to 5%, the microcomputer 7 skips 50% of the closest step dimming rate level in the dimming rate down direction to the step dimming rate level of 25%. Reduce the dimming rate. Thereby, the bathroom user can recognize that the incandescent lamp is clearly dimmed.

次に、浴室使用者が白熱灯2a,2bを明るくするために調光スイッチ5の調光率アップ用スイッチ5aを短時間、オンした場合、マイクロコンピュータ7により段階調光制御が行なわれる。現在の調光率PL(52パーセント)から調光率アップ方向での一番近い段階調光率レベルは75パーセントである。そのため、現在の調光率PLとの差は23パーセントであり、設定調光率差(5パーセント)を超えているため、マイクロコンピュータ7は、現在の調光率PL(52パーセント)から調光率アップ方向での一番近い段階調光率レベル75パーセントまで調光率を上げる。これにより、浴室使用者は、白熱灯が明らかに調光されたことを認識することができる。   Next, when the bathroom user turns on the dimming rate increasing switch 5a of the dimming switch 5 for a short time in order to brighten the incandescent lamps 2a and 2b, the microcomputer 7 performs step dimming control. The closest step dimming level in the direction of increasing the dimming rate from the current dimming rate PL (52%) is 75%. Therefore, the difference from the current dimming rate PL is 23%, which exceeds the set dimming rate difference (5%). Therefore, the microcomputer 7 performs dimming from the current dimming rate PL (52%). The dimming rate is increased to the closest step dimming level 75% in the direction of increasing the rate. Thereby, the bathroom user can recognize that the incandescent lamp is clearly dimmed.

以上説明したような特徴を有する調光装置1では、調光スイッチ5が上記のようにスイッチ5a(調光率アップ用),5b(調光率ダウン用)の二つを有しているが、これに限らず、一つのスイッチで、現在の調光率から例えば最大調光率レベルの方向に操作指示し、最大調光率レベルまで調光制御されると、今度は最小調光レベルの方向に操作指示されるようにすれば、調光スイッチ5を一つのスイッチにすることができる。この場合でも、図5に示したような調光装置1の調光制御の特徴は同じである。   In the light control device 1 having the characteristics as described above, the light control switch 5 has the two switches 5a (for dimming rate increase) and 5b (for dimming rate reduction) as described above. Not limited to this, if a switch is used to instruct the operation from the current dimming rate to the maximum dimming rate level, for example, and the dimming control is performed up to the maximum dimming rate level, then the minimum dimming level If the operation is instructed in the direction, the dimming switch 5 can be made into one switch. Even in this case, the dimming control features of the dimming device 1 as shown in FIG. 5 are the same.

また、以上の実施の形態では、調光装置1を浴室に適用した例を説明したが、浴室に限らず、洗面室、トイレット、ベッドルームなどで、白熱灯を調光する場合にも使用することができる。   Moreover, although the example which applied the light control apparatus 1 to the bathroom was demonstrated in the above embodiment, it uses also when dimming an incandescent lamp not only in a bathroom but in a washroom, a toilet, a bedroom, etc. be able to.
