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。 Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention.

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。 Figure 1 is a schematic exploded perspective view showing a configuration of a lighting device according to a 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。 The lighting device has a glass of one surface as the light guide member to illumination surface 1a, a light guide plate 1 made of plastic or the like, the illumination surface 1a of the light guide plate 1 is additionally provided on the opposite side, rectangular a rectangular detection electrode 2 having an opening 2a of the shape, and is configured by a light source 3 such as an LED providing light to the light guide plate 1 through the opening 2a of the detection electrode 2. ここで、導光板1と光源3とは、照光手段を構成している。 Here, the light guide plate 1 and the light source 3 constitute a lighting unit.

図2は、この照明装置の回路構成を示す回路図である。 Figure 2 is a circuit diagram showing a circuit configuration of the lighting device.

検知電極2は、静電容量検知回路11に接続されている。 Sense electrode 2 is connected to the capacitance sensing circuit 11. 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。 Capacitance sensing circuit 11 outputs a detection value corresponding to the capacitance between the ground and sensing electrodes 2. 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。 The detection circuit 11, for example, those incorporating an oscillation circuit to generate a signal oscillating frequency or duty ratio changes in accordance with the electrostatic capacitance Cx produced by the sensing electrodes 2. 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。 Detection value output from the detection circuit 11 is inputted to the determination circuit 12. 判定回路12は、コンパレータ121を備えて構成されている。 Judging circuit 12 is constituted by a comparator 121. 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。 The comparator 121 receives the detected values ​​from the capacitance sensing circuit 11 to one input terminal, the other input terminal receives the first determination voltage generated by the decision voltage generation circuit 122, the detection value is a and it outputs a first detection signal when exceeding the first judgment voltage. この第1検知信号は、照明点灯制御回路13に入力される。 The first detection signal is input to the illumination lighting control circuit 13. 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。 Lighting lighting control circuit 13, when the light source 3 is non-lighting state, when the output from the decision circuit 12 is turned ON, the light source 3 is turned in a first state, the ON state is continuously fixed period if the light source 3 is turned in the second state. 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。 The illumination lighting control circuit 13, when the light source 3 is lit, the output from the decision circuit 12 turns off the light source 3 with that becomes constant time ON state. 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。 Here, the first states temporary lighting state, and the second state is the on state, since the former may if check the position of the switch, the luminance may be smaller than the latter. 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。 The former red light, the latter may be changed lighting color and so white light the. 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。 Light source drive circuit 14 drives the light source 3 when the output of the illumination lighting control circuit 13 is ON state.

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, the operation of the lighting apparatus according to the thus constructed embodiment.

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。 In off state, the human body sensing electrode 2, for example, finger approaches (e.g. contact the light guide plate 1), the capacitance to ground through the body of the detection electrode 2 changes, this result, the output from the capacitance sensing circuit 11 detection value increases. 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。 Lighting lighting control circuit 13, the detection value from the capacitance sensing circuit 11 upon detecting the determination circuit 12 that exceeds the first determination voltage, and drives the optical drive circuit 14 is provisionally on the light source 3. 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。 Detected value Once beyond the first determination voltage continuously for a predetermined time (1-2 seconds), the turns on the light source 3 by driving the optical drive circuit 14. 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。 Further, in the lighting state, approaching human body detection electrode 2 (e.g. in contact with the light guide plate 1), the capacitance to ground of the detection electrode 2 changes. 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 the detection value from the capacitance sensing circuit 11 exceeds the first determination voltage predetermined time, the output of the illumination lighting control circuit 13 is inverted from the ON state to the OFF state, 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。 According to the lighting apparatus of the present embodiment, since the back surface of the light guide plate 1 having the illuminating surface 1a is sense electrode 2 is arranged, the position of the switch for on or off is illuminating surface 1a itself, operator, because the light source 3 simply by holding the hand in the vicinity of temporarily turned, the position of the switch is clarified, the lighting operation is facilitated. 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。 If increasing the detection sensitivity of the capacitance sensing circuit 11, it is possible to provisionally on the light source 3 in a wider range, 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 embodiment, at the time and / or off transition the lighting transition, by the light source 3 and blinking state, the switch is to notify to ensure the operator that the ON state or the OFF state , 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。 Further, even when the light source 3 to the OFF state, the light source 3 when the detected value from the capacitance sensing circuit 11 exceeds the first determination voltage and temporary lighting state, then, be unlit good. 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。 In this way, there is a problem that is illuminated by only the person has approached darkened, it is effective to inform that are in the off state to the operator, 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。 Figure 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。 In this embodiment, it is arranged detection electrodes 2 'on the illuminating surface 1a of the light guide plate 1. 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 case, the detection electrodes 2 'for covering the illuminating surface 1a of the light guide plate 1 is constituted by a transparent electrode.

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 this structure, the detection electrodes 2 'is not a back side of the light guide plate 1, since it is arranged on the operating side, it is possible to further reduce the proximity distance between the human body, it is possible to further improve the detection sensitivity .

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 the comparator 121 is two, the illumination lighting control circuit 13 'is allowed to light source 3 and the temporary lighting state when the detected value from the capacitance sensing circuit 11 exceeds the first determination voltage, the detection value There can be a present lighting state lighting lighting control circuit 13 'when it exceeds the second determination voltage.

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 the comparator 121 is three or more, since it is possible to light up at a luminance corresponding to the distance between the finer human body, there is an advantage that it is easy to find the direction in which the presence of the switch.
