Description

本発明は、LED照明機器の調光制御方法に関し、特に、長距離の省配線で一括して調光を可能とするLED照明機器の調光制御方法に関するものである。   The present invention relates to a dimming control method for an LED lighting device, and more particularly to a dimming control method for an LED lighting device that enables dimming in a lump with long-distance wiring saving.

近年の省エネルギ化の機運の高まりから、各種のLED照明機器が汎用され、これに伴い、種々のLED照明機器の調光制御方法が提案されている(例えば、特許文献1−2参照。)。   Due to the recent increase in energy saving momentum, various LED lighting devices have been widely used, and accordingly, dimming control methods for various LED lighting devices have been proposed (for example, see Patent Document 1-2). .

ところで、LED照明機器の調光制御方法として、近年になって、交流電源を一旦コンバータで直流に変換し、この直流電圧をLEDに供給する技術が開発されているが、LED照明機器に用いられるLEDは、商用点灯するのが一般的であるため、必要以上に明るい場合があり、これに対処するため、調光制御する必要がある。   By the way, as a dimming control method for LED lighting equipment, in recent years, a technique has been developed in which an AC power supply is once converted into DC by a converter and this DC voltage is supplied to the LED. Since the LED is generally turned on for commercial use, it may be brighter than necessary. In order to cope with this, it is necessary to perform dimming control.

そして、このLEDの調光制御方式として、0〜10Vの電圧信号による調光制御方式を採用したものがあるが、例えば、モータ駆動部にインバータ制御機構が採用されているごみクレーンに備えられるLED照明機器にこの調光制御方式を採用すると、インバータ制御機構の誘導ノイズの影響を受けやすく、さらに、配線距離が長いため、電圧信号の電圧降下によって制御が不安定になったり、不能になるという問題があった。   In addition, as a dimming control method of this LED, there is one that adopts a dimming control method using a voltage signal of 0 to 10 V. For example, an LED provided in a garbage crane in which an inverter control mechanism is adopted in a motor drive unit. If this dimming control method is used for lighting equipment, it is easy to be affected by the induction noise of the inverter control mechanism, and furthermore, because the wiring distance is long, the control becomes unstable or impossible due to the voltage drop of the voltage signal. There was a problem.

また、一般産業用天井クレーンの操作部に採用されている2段押ボタンスイッチによっては、ON−OFF操作が行えるのみで、無段階のLEDの調光制御を行うことができないという問題があった。   In addition, the two-stage pushbutton switch employed in the operation section of a general industrial overhead crane has a problem that it can only perform ON-OFF operation and cannot perform stepless LED light control. .
