Description

本発明は、光源として複数のＬＥＤユニットを装備するＬＥＤ照明器具に関する。   The present invention relates to an LED lighting apparatus equipped with a plurality of LED units as a light source.

従来より、照明器具に対する最初の電源投入時において、調光制御部における制御目標値を自動判別し、以後その制御目標値になるようにランプの明るさを制御するＬＥＤ照明器具が知られている（例えば、特許文献１参照）。
また、ＬＥＤユニットに供給される電流のオンおよびオフを切り換える第１のスイッチング回路と、ＬＥＤユニットに一定の電流が流れるように第１のスイッチング回路のスイッチング動作を第２のＰＷＭで制御するＰＷＭ制御回路と、ＰＷＭ信号発生回路から出力されるＰＷＭ信号のＰＷＭ波形がハイとなる間に、ＰＷＭ制御回路による第１のスイッチング回路のスイッチング動作をオンにする第２のスイッチング回路とを備えるＬＥＤ照明器具が知られている（例えば、特許文献２参照）。 2.

特開２００３−１６８５７３号公報（図１、請求項１）Japanese Patent Laying-Open No. 2003-168573 (FIG. 1, claim 1) 特開２００９−２６５４４号公報（図１、請求項１）Japanese Patent Laying-Open No. 2009-26544 (FIG. 1, claim 1)

前述した特許文献１に記載されたＬＥＤ照明器具は、初期設定操作において、ＬＥＤ照明器具の電源投入時において、自動的に制御目標値を判別するようにしたので、初期設定の手間を低減することができる。
前述した特許文献２に記載されたＬＥＤ照明器具は、サイリスタ式の調光装置でＬＥＤユニットの調光を制御しようとした場合でも、ＬＥＤユニットの照度を調光の設定に応じて適切に制御できる。
ところで、蛍光灯を光源とし、リモコン送信器からの明るさを制御する信号を受信すると、１つの蛍光灯または２つの蛍光灯の明るさを同時に変更できる照明器具が提案されている。
しかし、このような従来の照明器具において、複数の蛍光灯を個別に制御できないばかりか、光が照射される全部の領域について同時に調光が制御されてしまう。
従って、このような従来の照明器具は、人がいる領域を明るくし、これとは異なり、明るさの不必要な領域は暗くするといった省エネルギー効果を得るための制御ができない。
一方、前述した特許文献１に記載されたＬＥＤ照明器具は、初期設定の手間を低減することができるものの、人がいる領域を明るくし、明るさの不必要な領域は暗くするといった制御ができない。
加えて、前述した特許文献２に記載されたＬＥＤ照明器具は、ＬＥＤユニットの照度を調光の設定に応じて適切に制御できるものの、人がいる領域を明るくし、明るさの不必要な領域は暗くするといった制御ができない。 Since the LED lighting apparatus described in Patent Document 1 described above is configured to automatically determine the control target value when the LED lighting apparatus is turned on in the initial setting operation, the effort for the initial setting is reduced. Can do.
The LED lighting apparatus described in Patent Document 2 described above can appropriately control the illuminance of the LED unit according to the dimming setting even when the dimming of the LED unit is controlled by a thyristor type dimming device. .
By the way, the lighting fixture which can change the brightness of one fluorescent lamp or two fluorescent lamps simultaneously is received when the signal which controls the brightness from a fluorescent lamp as a light source is received from the remote control transmitter.
However, in such a conventional lighting fixture, not only can a plurality of fluorescent lamps be individually controlled, but also dimming is controlled simultaneously for all the areas irradiated with light.
Therefore, such a conventional lighting device cannot perform control for obtaining an energy saving effect such that a region where a person is present is brightened and a region where brightness is unnecessary is darkened.
On the other hand, although the LED lighting apparatus described in Patent Document 1 described above can reduce the initial setting effort, it is not possible to control to brighten an area where a person is present and to darken an unnecessary area. .
In addition, although the LED lighting apparatus described in Patent Document 2 described above can appropriately control the illuminance of the LED unit according to the dimming setting, the area where the person is present is brightened and the area where brightness is unnecessary Cannot be controlled to darken.

本発明は、前述した課題を解決するためになされたものであり、所定の領域毎に明るさを制御することにより、余分な消費電力を抑制して省エネルギー化を図って環境負荷を少なくできるＬＥＤ照明器具を提供することにある。   The present invention has been made to solve the above-described problems, and by controlling the brightness for each predetermined region, an LED that can reduce energy consumption by suppressing excess power consumption and reducing energy consumption. It is to provide a luminaire.
