Description

本発明は、設置された環境の明るさを検出し、蛍光ランプの明るさを自動制御することができる照明装置に関するものである。   The present invention relates to a lighting device capable of detecting the brightness of an installed environment and automatically controlling the brightness of a fluorescent lamp.

従来より、会議室、オフィスなどの省電力を目的とした証明システムとして、照度センサにより周囲環境の照度を検出して、略一定の照度を保つように蛍光ランプの光出力を自動制御する照明器具が知られている。このような照明器具においては、照度センサが蛍光ランプの自発光を検出すると、周囲の正確な明るさを検出できないため、正確な制御ができない。このため、照度センサが自発光を検出しないようにすることが重要である。   Conventionally, as a proof system aiming at power saving in conference rooms, offices, etc., lighting equipment that automatically controls the light output of fluorescent lamps so that the illuminance sensor detects the illuminance of the surrounding environment and maintains a substantially constant illuminance It has been known. In such a luminaire, when the illuminance sensor detects the self-emission of the fluorescent lamp, the surrounding brightness cannot be detected accurately, so that accurate control cannot be performed. For this reason, it is important that the illuminance sensor does not detect spontaneous light emission.

例えば、図4(A)に示す照明器具100Aは、照明器具100Aの端面部で蛍光ランプ105からできるだけ離れた位置にセンサ受光ユニット101を一体的に取り付けたセンサ受光ユニット一体型である。照明器具100Aは、例えば下方に開口した箱形の器具本体102と、この器具本体102の長手方向に沿って設けられた反射板103を有している。反射板103の両端部にはランプソケット104が設けられており、直管型の蛍光ランプ105が着脱可能に取り付けられている。センサ受光ユニット101は、明るさを検知する照度センサ101aを有している。   For example, the lighting fixture 100A shown in FIG. 4A is a sensor light receiving unit integrated type in which the sensor light receiving unit 101 is integrally attached at a position as far as possible from the fluorescent lamp 105 at the end face of the lighting fixture 100A. 100 A of lighting fixtures have the box-shaped instrument main body 102 opened downward, for example, and the reflecting plate 103 provided along the longitudinal direction of this instrument main body 102. As shown in FIG. Lamp sockets 104 are provided at both ends of the reflector 103, and a straight tube type fluorescent lamp 105 is detachably attached. The sensor light receiving unit 101 includes an illuminance sensor 101a that detects brightness.

また、図4(B)および(C)に示す照明器具100B,100Cは、照明器具100B,100Cの外側にセンサ受光ユニット101B,101Cを別個に設けた、センサ受光ユニット別置型である。図4(B)に示す照明器具100Bは、矩形箱形の筐体106に照度センサ101aを設けたものである。図4(C)に示す照明器具100Cは、円筒形状の筐体107に照度センサ101aを設けたものである。   Also, the lighting fixtures 100B and 100C shown in FIGS. 4B and 4C are sensor light receiving unit separate types in which sensor light receiving units 101B and 101C are separately provided outside the lighting fixtures 100B and 100C. A lighting fixture 100B illustrated in FIG. 4B includes a rectangular box-shaped casing 106 and an illuminance sensor 101a. A lighting fixture 100C illustrated in FIG. 4C includes a cylindrical housing 107 provided with an illuminance sensor 101a.

しかしながら、これらの照明器具100A〜100Cにおいては、センサ受光ユニット101を別途設ける必要があり、全体が大型化するという問題がある。   However, in these lighting fixtures 100A to 100C, it is necessary to separately provide the sensor light receiving unit 101, and there is a problem that the whole is increased in size.

そこで、照度センサを器具本体の内部に設けて、コンパクト化を図った照明器具がある(例えば特許文献1参照)。
図5に示すように、特許文献1に記載の照明器具110では、下方に開口した矩形箱状の器具本体111を有しており、器具本体111内部には、蛍光ランプ112の光を反射する反射板113が取り付けられている。反射板113の端部には検知用穴が設けられており、この検知用穴の内部には周囲の明るさを検知する照度センサ114が取り付けられている。なお、検知用穴には筒状の遮光筒が取り付けられており、明るさを検知する際に蛍光ランプ112による自発光の影響を少なくしている。
特開平10−302535号公報(第1図)
Therefore, there is a lighting fixture that is made compact by providing an illuminance sensor inside the fixture body (see, for example, Patent Document 1).
As shown in FIG. 5, the lighting fixture 110 described in Patent Document 1 has a rectangular box-shaped fixture body 111 that opens downward, and reflects light from the fluorescent lamp 112 inside the fixture body 111. A reflection plate 113 is attached. A detection hole is provided at the end of the reflection plate 113, and an illuminance sensor 114 for detecting ambient brightness is attached inside the detection hole. In addition, a cylindrical light shielding cylinder is attached to the detection hole, so that the influence of the self-light emission by the fluorescent lamp 112 is reduced when the brightness is detected.
Japanese Patent Laid-Open No. 10-302535 (FIG. 1)

ところで、近年、家庭用に用いられる照明器具においても、前述した照明器具100、110と同様に、省電力の観点から、環境の明るさを略一定に保つように蛍光ランプの出力を自動制御することが行われるようになってきた。
しかしながら、家庭用の照明器具として一般的に用いられる環形の蛍光ランプを用いた場合には全体的に明るさが均一なので、前述した照明器具100、110のように直管型の蛍光ランプ105、112を用いた場合のように、自発光の影響が少ない場所がない。さらに、家庭用の照明器具においては、カバー部材が設けられるのが一般的であり、カバー部材の内部においては自発光が乱反射するので、自発光の影響を受け易いという問題があった。
By the way, in recent years as well as lighting fixtures 100 and 110 described above, the lighting fixtures used for home use automatically control the output of the fluorescent lamp so as to keep the brightness of the environment substantially constant from the viewpoint of power saving. Things have come to be done.
However, when a ring-shaped fluorescent lamp that is generally used as a home lighting fixture is used, the overall brightness is uniform. Therefore, like the above-described lighting fixtures 100 and 110, a straight fluorescent lamp 105, There is no place where the influence of self-light emission is small as in the case of using 112. Furthermore, in general lighting fixtures for home use, a cover member is generally provided. Since the self-light emission is irregularly reflected inside the cover member, there is a problem that it is easily affected by the self-light emission.

本発明は、従来の問題を解決するためになされたもので、環形の蛍光ランプを用いた照明器具において、明るさ検出手段を一体的に設けるとともに、自発光の影響を小さくして、環境の明るさを一定に保つように自動制御できる照明装置を提供することを目的とする。   The present invention has been made in order to solve the conventional problems. In a lighting apparatus using a ring-shaped fluorescent lamp, the brightness detection means is provided integrally, and the influence of self-light emission is reduced, thereby reducing environmental effects. An object of the present invention is to provide an illumination device that can be automatically controlled so as to keep the brightness constant.

本発明の照明装置は、光源と、前記光源を収容する器具本体と、前記器具本体に取り付けられて前記光源を覆うカバー部材と、前記光源を点灯させる点灯装置と、前記光源により照らされる被照射面の照度を検出する明るさ検出手段と、前記明るさ検出手段による検出値を受けて前記光源の光出力を制御する制御部とを備えた照明装置であって、前記器具本体が角形であり、前記明るさ検出手段を前記器具本体の角部でかつ前記カバー部材の外に設けた構成を有している。   The illumination device of the present invention includes a light source, an instrument main body that accommodates the light source, a cover member that is attached to the instrument main body and covers the light source, a lighting device that lights the light source, and an irradiation object that is illuminated by the light source. A lighting device comprising brightness detection means for detecting the illuminance of a surface, and a control unit for receiving a detection value from the brightness detection means and controlling the light output of the light source, wherein the fixture body is square. The brightness detecting means is provided at the corner of the instrument body and outside the cover member.

この構成により、光源により照らされる被照射面の照度を検出する明るさ検出手段を、角形の器具本体の角部でかつ光源を覆うカバー部材の外に設けたので、明るさ検出手段を一体的に設けながら、光源による自発光の影響を小さくして被照射面の照度を検出することができる。このため、明るさ検出手段による検出値を受けて制御部が光源の光出力を制御する際に、周囲の環境の明るさを正確に把握して、環境の明るさを一定に保つように自動制御することができる。   With this configuration, the brightness detection means for detecting the illuminance of the illuminated surface illuminated by the light source is provided at the corner of the square instrument body and outside the cover member that covers the light source. In this case, it is possible to detect the illuminance of the irradiated surface while reducing the influence of the self-light emission by the light source. For this reason, when the control unit receives the detection value from the brightness detection means and controls the light output of the light source, it automatically grasps the brightness of the surrounding environment and automatically keeps the brightness of the environment constant. Can be controlled.

また、本発明の照明装置は、前記光源は最外周に口金部を有する環形の蛍光ランプであり、前記蛍光ランプの中心点と前記明るさ検出手段を結ぶ直線上に前記口金部が配置された構成を有している。   Further, in the illumination device of the present invention, the light source is an annular fluorescent lamp having a base portion on the outermost periphery, and the base portion is arranged on a straight line connecting a center point of the fluorescent lamp and the brightness detecting means. It has a configuration.

この構成により、明るさ検出手段を、蛍光ランプの中心点と口金部とを結ぶ直線の延長上に配置したので、蛍光ランプの自発光は口金部により遮られて明るさ検出手段に直接照射されない。これにより、光源による自発光の影響を小さくして被照射面の照度を検出することができ、環境の明るさを一定に保つように自動制御できる。   With this configuration, since the brightness detection means is arranged on an extension of a straight line connecting the center point of the fluorescent lamp and the base part, the self-emission of the fluorescent lamp is blocked by the base part and is not directly irradiated to the brightness detection means. . Thereby, it is possible to detect the illuminance of the irradiated surface by reducing the influence of the self-light emission by the light source, and to automatically control the brightness of the environment to be constant.

本発明は、光源により照らされる被照射面の照度を検出する明るさ検出手段を、角形の器具本体の角部でかつ光源を覆うカバー部材の外に設けたので、明るさ検出手段を一体的に設けながら、光源による自発光の影響を小さくして被照射面の照度を検出することができる。このため、明るさ検出手段による検出値を受けて制御部が光源の光出力を制御する際に、周囲の環境の明るさを正確に把握して、環境の明るさを一定に保つように自動制御することができるものである。   In the present invention, since the brightness detection means for detecting the illuminance of the irradiated surface illuminated by the light source is provided at the corner of the square instrument body and outside the cover member covering the light source, the brightness detection means is integrated. In this case, it is possible to detect the illuminance of the irradiated surface while reducing the influence of the self-light emission by the light source. For this reason, when the control unit receives the detection value from the brightness detection means and controls the light output of the light source, it automatically grasps the brightness of the surrounding environment and automatically keeps the brightness of the environment constant. It can be controlled.

以下、本発明の実施の形態の照明装置について、図面を用いて説明する。

Hereinafter, an illumination device according to an embodiment of the present invention will be described with reference to the drawings.
(First embodiment)

It is a block block diagram of the illuminating device concerning.

図1および図2に示すように、本発明にかかる照明装置10は、例えば天井11に取り付けて使用される。照明装置10は、取付具12を介して天井11に取り付けられる器具本体13と、器具本体13に取り付けられる光源である環形の蛍光ランプ14と、器具本体13に取り付けられて蛍光ランプ14を覆うカバー部材15と、蛍光ランプ14を点灯させる点灯装置16と、点灯装置16を制御して蛍光ランプ14の光出力を調整する制御部17を有している。   As shown in FIGS. 1 and 2, the lighting device 10 according to the present invention is used by being attached to a ceiling 11, for example. The lighting device 10 includes a fixture main body 13 that is attached to the ceiling 11 via a fixture 12, a ring-shaped fluorescent lamp 14 that is a light source attached to the fixture main body 13, and a cover that is attached to the fixture main body 13 and covers the fluorescent lamp 14. A member 15, a lighting device 16 that turns on the fluorescent lamp 14, and a control unit 17 that controls the lighting device 16 to adjust the light output of the fluorescent lamp 14.

器具本体13は角形をしており、いずれかの角部に明るさ検出手段である照度センサ18が取り付けられている。照度センサ18が設けられている角部に対応するカバー部材15の角部には、凹部15aが設けられており、照度センサ18はカバー部財15の外側に配置されることになる。また、器具本体13の中央部には反射板19が設けられており、反射板19の裏側(内部)に、点灯装置16や制御部17が配置されている。   The appliance main body 13 has a square shape, and an illuminance sensor 18 serving as a brightness detection means is attached to one of the corners. Concave portions 15 a are provided at the corners of the cover member 15 corresponding to the corners where the illuminance sensor 18 is provided, and the illuminance sensor 18 is disposed outside the cover member 15. In addition, a reflector 19 is provided at the center of the instrument body 13, and a lighting device 16 and a controller 17 are disposed on the back side (inside) of the reflector 19.

環形の蛍光ランプ14の一部(端部)には、電力を蛍光ランプ14に供給するためのランプピン(図示省略)を有する口金部14aが設けられている。この口金部14aは発光しない。また、口金部14aは、蛍光ランプ14の他の部分からの光を遮る。口金部14aは、蛍光ランプ14の中心点と照度センサ18が設けられている角部とを結ぶ直線上に配置されている。   A part (end part) of the annular fluorescent lamp 14 is provided with a base part 14 a having a lamp pin (not shown) for supplying electric power to the fluorescent lamp 14. The base part 14a does not emit light. The base portion 14 a blocks light from other parts of the fluorescent lamp 14. The base part 14 a is arranged on a straight line connecting the center point of the fluorescent lamp 14 and the corner part where the illuminance sensor 18 is provided.

従って、照度センサ18は、蛍光ランプ14の中心と口金部14aを結んだ直線の延長上に設けられることになり、蛍光ランプ14の自発光が口金部14aにより遮られる範囲に位置する。このため、照度センサ18が被照射面の照度を検知する際に、蛍光ランプ14の自発光の影響を小さくすることができ、照度を制度良く検出することができる。   Therefore, the illuminance sensor 18 is provided on an extension of a straight line connecting the center of the fluorescent lamp 14 and the base part 14a, and is located in a range where the self-light emission of the fluorescent lamp 14 is blocked by the base part 14a. For this reason, when the illuminance sensor 18 detects the illuminance on the irradiated surface, the influence of the self-light emission of the fluorescent lamp 14 can be reduced, and the illuminance can be detected in a systematic manner.

図2に示すように、照度センサ18は制御部17に接続されており、制御部17は点灯装置16を制御して、蛍光ランプ14の光出力を制御する。すなわち、制御部17によって制御された蛍光ランプ14により照らされた被照射面20の明るさを照度センサ18が検知し、検知信号を制御部17に送り、この検知信号に基づいて制御部17が蛍光ランプ14の光出力を制御して、被照射面20の明るさを一定に保持する。   As shown in FIG. 2, the illuminance sensor 18 is connected to the control unit 17, and the control unit 17 controls the lighting device 16 to control the light output of the fluorescent lamp 14. That is, the illuminance sensor 18 detects the brightness of the illuminated surface 20 illuminated by the fluorescent lamp 14 controlled by the control unit 17, sends a detection signal to the control unit 17, and based on this detection signal, the control unit 17 The light output of the fluorescent lamp 14 is controlled to keep the brightness of the illuminated surface 20 constant.

以上、説明した本発明にかかる照明装置10によれば、蛍光ランプ14により照らされる被照射面20の照度を検出する照度センサ18を、角形の器具本体13の角部でかつカバー部材15の外に設けたので、照度センサ18を一体的に設けながら、蛍光ランプ14による自発光の影響を小さくして被照射面20の照度を制度よく検出することができる。このため、照度センサ18による検出値を受けて制御部17が蛍光ランプ14の光出力を制御する際に、周囲の環境の明るさを正確に把握して、環境の明るさを一定に保つように自動制御することができる。   As described above, according to the illuminating device 10 according to the present invention described above, the illuminance sensor 18 that detects the illuminance of the irradiated surface 20 illuminated by the fluorescent lamp 14 is provided at the corner of the square instrument body 13 and outside the cover member 15. Therefore, while the illuminance sensor 18 is provided integrally, the influence of the self-light emission by the fluorescent lamp 14 can be reduced and the illuminance of the irradiated surface 20 can be detected systematically. For this reason, when the controller 17 receives the detection value from the illuminance sensor 18 and controls the light output of the fluorescent lamp 14, it accurately grasps the brightness of the surrounding environment and keeps the brightness of the environment constant. Can be automatically controlled.
