従来より、静電容量の変化を検出して光源を点灯させる照明装置として特許文献１に開示のものが知られている。この照明装置は、人体の接近を検知する電極と、この電極の静電容量の変化を検出する静電容量式センサと、静電容量式センサからの所定の時間幅を有する出力に応動して光源の点灯又は消灯制御を行う制御回路とを備えたものである。 Conventionally, a device disclosed in Patent Document 1 is known as an illumination device that detects a change in capacitance and turns on a light source. This illumination device is responsive to an output having a predetermined time width from an electrode that detects the approach of a human body, a capacitance sensor that detects a change in capacitance of the electrode, and the capacitance sensor. And a control circuit that controls turning on or off the light source.
この照明装置によれば、点灯又は消灯の意志を持った操作者の手の動きのみに反応し、それ以外のものの動きには反応しない照明装置を提供することができる。
しかしながら、上述した従来の照明装置では、真っ暗な環境でどこにスイッチが存在するか分からない場合に、照明を点灯させることが困難であるという問題がある。 However, the above-described conventional illumination device has a problem that it is difficult to turn on the illumination when it is not known where the switch exists in a dark environment.
本発明は、このような点に鑑みてなされたもので、スイッチの位置が分からない環境下でもスムーズな点灯操作を行うことが可能な照明装置を提供することを目的とする。 The present invention has been made in view of such a point, and an object of the present invention is to provide an illuminating device capable of performing a smooth lighting operation even in an environment where the position of a switch is not known.
本発明に係る照明装置は、照光面を有する照光手段と、この照光手段の前記照光面に対応する位置に配置された検知電極と、この検知電極と接地との間の静電容量を検出してこれに対応した検出値を出力する静電容量検知回路と、この静電容量検知回路から出力される検出値が所定のしきい値を超えたときに前記照光手段を第１の状態で点灯させ、前記検出値が所定の条件を満足したら前記照光手段を第２の状態で点灯させる制御回路とを有することを特徴とする。 An illuminating device according to the present invention detects an electrostatic capacity between an illuminating unit having an illuminating surface, a detecting electrode disposed at a position corresponding to the illuminating surface of the illuminating unit, and the detecting electrode and ground.

本発明によれば、検知電極と人体とが接近することにより静電容量検知回路から出力される検出値が、所定のしきい値を超えたときに照光手段を第１の状態で点灯させ、検出値が所定の条件を満足したら前記照光手段を第２の状態に点灯させるようにしているので、例えば手などを照光手段の近くにかざすことで、照光手段を第１の状態で仮点灯させ、続いて仮点灯により場所が把握できた照光手段に手を接触させるか、又は手を仮点灯状態となった位置に暫く保持させること等により、本点灯状態に移行させることができ、スイッチ位置が分からなくても、支障のない点灯操作を行うことが可能となる。 According to the present invention, when the detection value output from the capacitance detection circuit by approaching the detection electrode and the human body exceeds a predetermined threshold value, the illumination means is turned on in the first state, If the detected value satisfies a predetermined condition, the illumination means is turned on in the second state. For example, by holding the hand close to the illumination means, the illumination means is temporarily turned on in the first state. Then, it is possible to shift to the main lighting state by bringing the hand into contact with the illumination means whose location has been grasped by temporary lighting, or by holding the hand for a while at the position where the temporary lighting state has been reached. Even without knowing, it is possible to perform a lighting operation without any problem.
以下、添付の図面を参照して、本発明の実施の形態を説明する。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
図１は、本発明の第１の実施形態に係る照明装置の構成を示す概略的な分解斜視図である。 FIG. 1 is a schematic exploded perspective view showing a configuration of a lighting apparatus according to the first embodiment of the present invention.
この照明装置は、一方の面を照光面１ａとする導光部材としてのガラス、プラスチック等からなる導光板１と、この導光板１の照光面１ａとは反対側の面に添設され、矩形状の開口部２ａを有する矩形状の検知電極２と、この検知電極２の開口部２ａを通して導光板１に光を供給するＬＥＤ等の光源３とを備えて構成されている。ここで、導光板１と光源３とは、照光手段を構成している。 This illuminating device is attached to a light guide plate 1 made of glass, plastic or the like as a light guide member having one surface as an illumination surface 1a, and a surface opposite to the illumination surface 1a of the light guide plate 1. A rectangular detection electrode 2 having a shape opening 2 a and a light source 3 such as an LED that supplies light to the light guide plate 1 through the opening 2 a of the detection electrode 2 are configured. Here, the light guide plate 1 and the light source 3 constitute illumination means.
図２は、この照明装置の回路構成を示す回路図である。 FIG. 2 is a circuit diagram showing a circuit configuration of the illumination device.
検知電極２は、静電容量検知回路１１に接続されている。静電容量検知回路１１は、検知電極２と接地との間の静電容量に応じた検出値を出力する。この検知回路１１は、例えば発振回路を内蔵し、検知電極２によって生成される静電容量Ｃｘに応じて発振周波数又はデューティー比が変化する信号を生成するものである。この検知回路１１から出力される検出値は、判定回路１２に入力されている。判定回路１２は、コンパレータ１２１を備えて構成されている。コンパレータ１２１は、一方の入力端に静電容量検知回路１１からの検出値を入力し、他方の入力端に、判定電圧生成回路１２２で生成された第１判定電圧を入力し、検出値が第１判定電圧を超えたときに第１検知信号を出力する。この第１検知信号は、照明点灯制御回路１３に入力される。照明点灯制御回路１３は、光源３が非点灯状態であるときに、判定回路１２からの出力がＯＮ状態になったら、第１の状態で光源３を点灯させ、一定期間連続してＯＮ状態であれば、第２の状態で光源３を点灯させる。また、照明点灯制御回路１３は、光源３が点灯状態であるときに、判定回路１２からの出力が一定時間ＯＮ状態となったことをもって光源３を消灯させる。ここで、第１の状態とは仮点灯状態、第２の状態とは本点灯状態であり、前者はスイッチの位置を確認できれば良いので、後者よりも輝度は小さくても良い。また、前者を赤色点灯、後者を白色点灯というように点灯色を変えるようにしても良い。光源駆動回路１４は、照明点灯制御回路１３の出力がＯＮ状態となっているときに光源３を駆動する。 The detection electrode 2 is connected to the capacitance detection circuit 11. The capacitance detection circuit 11 outputs a detection value corresponding to the capacitance between the detection electrode 2 and the ground. The detection circuit 11 includes an oscillation circuit, for example, and generates a signal whose oscillation frequency or duty ratio changes according to the capacitance Cx generated by the detection electrode 2. The detection value output from the detection circuit 11 is input to the determination circuit 12. The determination circuit 12 includes a comparator 121. The comparator 121 inputs the detection value from the capacitance detection circuit 11 to one input terminal, and inputs the first determination voltage generated by the determination voltage generation circuit 122 to the other input terminal. A first detection signal is output when the determination voltage exceeds one. This first detection signal is input to the illumination lighting control circuit 13. The illumination lighting control circuit 13 turns on the light source 3 in the first state when the output from the determination circuit 12 is in the ON state when the light source 3 is in the non-lighting state. If there is, the light source 3 is turned on in the second state. Further, the illumination lighting control circuit 13 turns off the light source 3 when the output from the determination circuit 12 is in the ON state for a certain period of time when the light source 3 is in the lighting state. Here, the first state is a temporary lighting state, and the second state is a main lighting state. The former only needs to be able to confirm the position of the switch, and therefore the luminance may be smaller than the latter. Alternatively, the lighting color may be changed so that the former is lit red and the latter is lit white. The light source drive circuit 14 drives the light source 3 when the output of the illumination lighting control circuit 13 is ON.
次に、このように構成された本実施形態に係る照明装置の動作について説明する。 Next, operation | movement of the illuminating device based on this embodiment comprised in this way is demonstrated.
消灯状態において、検知電極２に人体、例えば指が接近（例えば導光板１に接触）すると、検知電極２の人体を介した対接地容量が変化し、この結果、静電容量検知回路１１から出力される検出値が増加する。照明点灯制御回路１３は、静電容量検知回路１１からの検出値が第１判定電圧を超えたことを判定回路１２が検出したら、光駆動回路１４を駆動して光源３を仮点灯させる。検出値が所定時間（１〜２秒）継続して第１判定電圧を超えたら、光駆動回路１４を駆動して光源３を本点灯させる。また、点灯状態において、検知電極２に人体が接近（例えば導光板１に接触）すると、検知電極２の対接地容量が変化する。静電容量検知回路１１からの検出値が第１判定電圧を所定時間超えると、照明点灯制御回路１３の出力がＯＮ状態からＯＦＦ状態に反転し、光源３がＯＦＦ状態となる。 When a human body, such as a finger, approaches the detection electrode 2 in the light-off state (for example, touches the light guide plate 1), the grounding capacitance of the detection electrode 2 through the human body changes, and as a result, output from the capacitance detection circuit 11 The detected value increases. When the determination circuit 12 detects that the detection value from the capacitance detection circuit 11 exceeds the first determination voltage, the illumination lighting control circuit 13 drives the light driving circuit 14 to temporarily turn on the light source 3. When the detection value continues for a predetermined time (1 to 2 seconds) and exceeds the first determination voltage, the light driving circuit 14 is driven to light the light source 3 permanently. Further, when the human body approaches the detection electrode 2 in the lighting state (for example, contacts the light guide plate 1), the ground capacitance of the detection electrode 2 changes. When the detection value from the capacitance detection circuit 11 exceeds the first determination voltage for a predetermined time, the output of the illumination lighting control circuit 13 is reversed from the ON state to the OFF state, and the light source 3 is turned OFF.
本実施形態の照明装置によれば、照光面１ａを有する導光板１の裏面に検知電極２が配置されているので、点灯又は消灯のためのスイッチの位置は、照光面１ａそれ自体であり、操作者は、その近傍に手をかざすだけで光源３が仮点灯するので、スイッチの位置が明確になり、点灯操作が容易になる。静電容量検知回路１１の検知感度を高めておけば、より広い範囲で光源３を仮点灯させることができ、操作性が更に向上する。 According to the illumination device of the present embodiment, since the detection electrode 2 is arranged on the back surface of the light guide plate 1 having the illumination surface 1a, the position of the switch for turning on or off is the illumination surface 1a itself, Since the light source 3 is temporarily turned on simply by holding the hand in the vicinity of the operator, the position of the switch becomes clear and the lighting operation becomes easy. If the detection sensitivity of the capacitance detection circuit 11 is increased, the light source 3 can be temporarily turned on in a wider range, and the operability is further improved.
なお、上記実施形態において、本点灯移行時及び／又は消灯移行時に、光源３を点滅状態とさせることにより、スイッチがＯＮ状態又はＯＦＦ状態となったことを操作者に確実に知らしめるようにすると、更に操作性は向上する。 In the above-described embodiment, when the light source 3 is turned on and / or the light is turned off, the light source 3 is made to blink so that the operator can be surely notified that the switch is turned on or turned off. Further, the operability is improved.
また、光源３をＯＦＦ状態とするときも、静電容量検知回路１１からの検出値が第１判定電圧を超えたときに光源３を仮点灯状態とし、その後、消灯状態とするようにしてもよい。このようにすると、人が接近しただけで照明が暗くなるという不具合があるが、消灯状態に入っていることを操作者に知らせるには有効であり、操作性は向上する。 Even when the light source 3 is turned off, the light source 3 is temporarily turned on when the detection value from the capacitance detection circuit 11 exceeds the first determination voltage, and then turned off. Good. In this way, there is a problem that the illumination is darkened only by approaching a person, but it is effective for notifying the operator that the light is in the extinguished state, and the operability is improved.
図３は、本発明の他の実施形態に係る照明装置の概略的な斜視図である。 FIG. 3 is a schematic perspective view of a lighting device according to another embodiment of the present invention.
この実施形態では、導光板１の照光面１ａに検知電極２′を配置している。この場合、検知電極２′は、導光板１の照光面１ａを覆うため、透明電極により構成されている。 In this embodiment, the detection electrode 2 ′ is disposed on the illumination surface 1 a of the light guide plate 1. In this case, the detection electrode 2 ′ is composed of a transparent electrode to cover the illumination surface 1 a of the light guide plate 1.
このような構成によれば、検知電極２′が導光板１の裏側ではなく、操作側に配置されるので、人体との近接距離を更に縮めることができ、検出感度をより向上させることができる。 According to such a configuration, the detection electrode 2 ′ is arranged not on the back side of the light guide plate 1 but on the operation side, so that the proximity distance to the human body can be further reduced, and the detection sensitivity can be further improved. .
図４は、本発明の更に他の実施形態に係る照明装置の電気的な構成を示すブロック図である。 FIG. 4 is a block diagram showing an electrical configuration of a lighting apparatus according to still another embodiment of the present invention.
この実施形態では、判定回路１２′が複数のコンパレータ１２１１，１２１２，…，１２１Ｎと複数の判定電圧生成回路１２２１，１２２２，…，１２２Ｎとより構成されている。判定電圧生成回路１２２１〜１２２Ｎからは、それぞれ電圧値の異なる第１〜第Ｎの判定電圧が出力されている。照明点灯制御回路１３′は、判定回路１２′の出力パターンから光源駆動回路１４による光源３の駆動パターンを変える。これにより、人体の接近の程度により、光源３の輝度を細かく設定することが可能になる。 In this embodiment, the determination circuit 12 'is a plurality of comparators 121 1, 121 2, ..., 121 N and a plurality of decision voltage generating circuit 122 1, 122 2, ..., are more configuration and 122 N. First to Nth determination voltages having different voltage values are output from the determination voltage generation circuits 122 1 to 122 N , respectively. The illumination lighting control circuit 13 ′ changes the drive pattern of the light source 3 by the light source drive circuit 14 from the output pattern of the determination circuit 12 ′. Thereby, it becomes possible to set the brightness | luminance of the light source 3 finely according to the degree of approach of a human body.
例えば、コンパレータ１２１が２つであれば、静電容量検知回路１１からの検出値が第１の判定電圧を超えたときに照明点灯制御回路１３′が光源３を仮点灯状態とさせ、検出値が第２の判定電圧を超えたときに照明点灯制御回路１３′を本点灯状態とさせることができる。 For example, if there are two comparators 121, when the detection value from the capacitance detection circuit 11 exceeds the first determination voltage, the illumination lighting control circuit 13 'causes the light source 3 to be temporarily turned on, and the detection value When the lighting voltage exceeds the second determination voltage, the lighting lighting control circuit 13 'can be brought into the full lighting state.
また、コンパレータ１２１が３つ以上のときには、更に細かく人体との距離に応じた輝度での点灯が可能であるから、スイッチの存在する方向を見つけ易いという利点がある。 Further, when there are three or more comparators 121, it is possible to turn on the light with a luminance corresponding to the distance from the human body more finely, so that there is an advantage that it is easy to find the direction in which the switch exists.

この実施形態では、検知電極２に人体が接近して光源３が点灯されると、その光が検知電極２の開口部２ａを介して意匠板１の裏面を照射するので、意匠板１の表面の照光面４ａが光って見えることになる。 In this embodiment, when the human body approaches the detection electrode 2 and the light source 3 is turned on, the light irradiates the back surface of the design plate 1 through the opening 2 a of the detection electrode 2. The illuminated surface 4a appears to shine.
図６は、本発明の更に他の実施形態に係る照明装置を示す概略的な斜視図である。この実施形態では、２つの光源３，５を用いている。この場合、光源３，５は、人体がある程度近づいた状態、人体が接触した状態の２段階で、段階的に点灯数を増加させて輝度を上げたり、異なる発光色の光源３，５を用いることにより、それらの点灯／非点灯の組み合わせで発光色を切り替える等の操作を行うことができる。 FIG. 6 is a schematic perspective view showing an illumination apparatus according to still another embodiment of the present invention. In this embodiment, two light sources 3 and 5 are used.

Thus, it is possible to perform an operation such as switching the emission color by a combination of lighting / non-lighting.
