Description

本発明は、電気的照明手段と共に人感センサーを含む節電型照明装置に関する。   The present invention relates to a power-saving illumination device including a human sensor together with an electrical illumination means.

下記特許文献１乃至３には、蛍光灯、白熱電灯或いはＬＥＤから構成することができる電気的照明手段と共に人体を検出する人感センサーとを含む節電型照明装置が開示されている。かような照明装置においては、手動で或いは人感センサーが人体を検出することによって開閉スイッチが閉成され照明手段が作動せしめられている状態において、人感センサーが人体を検出しなくなって所定時間が経過すると照明手段の作動が自動的に停止され、かくして開閉スイッチの開放が忘却される等に起因して不必要時に照明手段が作動し続けて電力が無駄に消費されることが回避される。   Patent Documents 1 to 3 below disclose a power-saving illumination device that includes an electric illumination means that can be constituted by a fluorescent lamp, an incandescent lamp, or an LED, and a human sensor that detects a human body. In such an illuminating device, in a state where the opening / closing switch is closed and the illuminating means is operated manually or when the human sensor detects the human body, the human sensor stops detecting the human body for a predetermined time. When the time elapses, the operation of the illumination means is automatically stopped, and thus it is avoided that the illumination means continues to operate when it is unnecessary due to forgetting to open the open / close switch, etc. .

而して、上述したとおりの従来の照明装置においては、人感センサーが人体を検出しない、従って照明手段を作動せしめる必要がない時には、照明手段の作動が停止せしめられ、これによって不必要時に照明手段が作動され続けて電力が無駄に消費されることが回避されるが、無駄な電力消費の回避が未だ充分ではない。更に詳述すると、人感センサーが人体を検出しなくなって所定時間が経過すると、照明手段の作動は停止されるが、人感センサー及び制御手段には電力が供給され続け、比較的少量ではあるが人感センサー及び制御手段において所謂待機電力が消費され続ける。   Thus, in the conventional lighting device as described above, when the human sensor does not detect the human body, and therefore it is not necessary to activate the illumination means, the operation of the illumination means is stopped. Although it is avoided that the means continues to be operated and power is wasted, it is still not sufficient to avoid wasted power consumption. More specifically, when the human sensor no longer detects the human body and the predetermined time has elapsed, the operation of the illumination unit is stopped, but power is continuously supplied to the human sensor and the control unit, which is a relatively small amount. However, so-called standby power continues to be consumed in the human sensor and the control means.

本発明は上記事実に鑑みてなされたものであり、その主たる目的は、人感センサーが人体を検出しなくなって所定時間が経過すると、照明手段による電力消費が停止されると共に人感センサー及び制御手段による待機電力消費も停止され、かくして無駄な電力消費の回避即ち節電が一層効果的に遂行される、新規且つ改良された照明装置を提供することである。   The present invention has been made in view of the above-mentioned facts, and its main purpose is to stop power consumption by the lighting means and to detect the human sensor and control when a predetermined time elapses when the human sensor stops detecting the human body. It is an object of the present invention to provide a new and improved lighting device in which standby power consumption by the means is also stopped, thus avoiding wasteful power consumption, that is, saving power more effectively.

本発明者は、鋭意検討の結果、人感センサーが人体を検出しなくなって所定時間を経過すると、照明手段と共に人感センサー及び制御手段を電源から切り離すように構成することによって、上記主たる技術的課題を達成することができることを見出した。   As a result of intensive studies, the present inventor has configured the above-described main technical features by separating the human sensor and the control unit from the power source together with the lighting unit when the human sensor no longer detects the human body and a predetermined time has elapsed. I have found that I can achieve the task.

即ち、本発明によれば、上記主たる技術的課題を達成する照明装置として、手動で開閉操作可能なスイッチ手段を含む電力供給回路を介して電源に接続される電気的照明手段、人感センサー及び制御手段を含む照明装置において、
該人感センサー及び該制御手段は該電力供給回路に並列接続された副回路に配設されており、
該スイッチ手段は該制御手段によっても開放可能であり、且つ該制御手段は計時手段を備えており、
該開閉スイッチが手動で閉成されて該照明手段が作動せしめられている状態において、該人感センサーが人体を検出しない状態が所定時間経過すると、該制御手段は該スイッチ手段を開放することによって該照明手段と共に該人感センサー及び該制御手段を該電源から切り離す、
ことを特徴とする照明装置が提供される。 That is, according to the present invention, as an illuminating device that achieves the main technical problem, an electrical illuminating means connected to a power source via a power supply circuit including a switch means that can be manually opened and closed, a human sensor, and In the lighting device including the control means,
The human sensor and the control means are arranged in a sub-circuit connected in parallel to the power supply circuit,
The switch means can also be opened by the control means, and the control means includes a time measuring means,
In a state where the opening / closing switch is manually closed and the illumination means is operated, when a state in which the human sensor does not detect a human body has elapsed for a predetermined time, the control means opens the switch means . Disconnecting the human sensor and the control means together with the illumination means from the power source;
An illumination device is provided.

該照明手段は他の形態の照明手段に比べて消費電力が少ないＬＥＤから構成されているのが好適である。好適実施形態においては、照明装置は机に装備され且つ接続プラグを介して商用電源に接続されるスタンド型であり、該照明手段は机上を照明する。   The illuminating means is preferably composed of LEDs that consume less power than other forms of illuminating means. In a preferred embodiment, the lighting device is a stand type mounted on a desk and connected to a commercial power supply via a connection plug, and the lighting means illuminates the desk.

本発明の照明装置においては、人感センサーが人体を検出しなくなって所定時間が経過すると、制御手段によって開閉スイッチ手段が開放されて、照明手段と共に人感センサー及び制御手段が電源から切り離され、これによって照明手段による無駄な電力消費が回避されると共に、人感センサー及び制御手段により待機電力消費が回避され、かくして無駄な電力消費の回避即ち節電が一層効果的に遂行される。   In the lighting device of the present invention, when the human sensor no longer detects the human body and a predetermined time has elapsed, the opening / closing switch unit is opened by the control unit, and the human sensor and the control unit are disconnected from the power source together with the lighting unit, As a result, wasteful power consumption by the illumination means is avoided and standby power consumption is avoided by the human sensor and the control means, thus avoiding wasteful power consumption, that is, saving power more effectively.

以下、本発明の照明装置の好適実施形態を図示している添付図面を参照して、更に詳細に説明する。   Hereinafter, a preferred embodiment of a lighting device according to the present invention will be described in more detail with reference to the accompanying drawings.

図１を参照して説明すると、図示の照明装置は机３の上に載置される（単なる載置に代えて適宜の連結具を介して机３に解除自在に連結することもできる）スタンド型照明装置２として構成されている。この照明装置２は静止枠４、可動枠６及び支持枠８から構成された支持枠構造を含んでいる。静止枠４は机上に載置するための略Ｔ字状脚部１０とこの脚部１０から上方に延出する直立部１２を有する。可動枠６はその下端部が静止枠４の上端部に適宜の連結機構を介して旋回自在に連結されており、実質上水平に延びる旋回軸線を中心として矢印Ａ及びＢで示す方向に旋回自在である。支持枠８はその基端部が可動枠６の上端部に適宜の連結機構を介して旋回自在に連結されており、実質上水平に延びる旋回軸線を中心として矢印Ｃ及びＤで示す方向に旋回自在である。   Referring to FIG. 1, the illustrated lighting device is placed on a desk 3 (it can be releasably connected to the desk 3 via an appropriate connector instead of simply placing). It is configured as a mold illumination device 2. The lighting device 2 includes a support frame structure including a stationary frame 4, a movable frame 6, and a support frame 8. The stationary frame 4 has a substantially T-shaped leg portion 10 for placing on the desk and an upright portion 12 extending upward from the leg portion 10. The movable frame 6 is pivotally connected at its lower end to the upper end of the stationary frame 4 via an appropriate coupling mechanism, and is pivotable in directions indicated by arrows A and B about a pivot axis extending substantially horizontally. It is. The base end of the support frame 8 is connected to the upper end of the movable frame 6 via an appropriate connecting mechanism so as to be rotatable. The support frame 8 is swiveled in a direction indicated by arrows C and D about a swiveling axis extending substantially horizontally. It is free.

静止枠４には電源コード１４が付設されており、この電源コード１４の先端にはプラグ１６が配設されている。静止枠４の直立部前面には、スイッチ手段１８及び人感センサー２０が配設されている。それ自体は周知の形態でよいスイッチ手段１８は、手動で開閉操作することができると共に、後述する制御手段によっても開放され得る形態である。それ自体は周知の適宜の形態のセンサーから構成することができる人感サンサー２０は、椅子に着座して机上で作業する人体の存在を検出する。支持枠８の前半部内には、消費電力が小さいＬＥＤであるのが好都合である電気的照明手段２２が着脱自在に装着されている。 A power cord 14 is attached to the stationary frame 4, and a plug 16 is disposed at the tip of the power cord 14. On the front surface of the upright portion of the stationary frame 4, a switch unit 18 and a human sensor 20 are provided. The switch means 18, which may be in a well-known form, can be manually opened and closed, and can be opened by a control means described later. The human presence sensor 20 which can be configured by a sensor of an appropriate form known per se detects the presence of a human body sitting on a chair and working on a desk. In the front half of the support frame 8 , an electrical illumination means 22 that is conveniently an LED with low power consumption is detachably mounted.

図１と共に図２を参照して説明を続けると、上記照明手段２２は電力供給回路２４を介してプラグ１６に接続されており、電力供給回路２４には上記スイッチ手段１８が配設されている。従って、プラグ１６を商用電源のコンセント（図示していない）に接続し、スイッチ手段１８を閉成すれば、照明手段２２に電力が供給されて照明手段２２が作動即ち点灯される。電力供給回路２４には副回路２６が付設されており、この副回路２６には上記人感センサー２０と共に制御手段２８が接続されている。マイクロコンピュターから構成することができる制御手段２８は計時手段３０を内蔵している。人感センサー２０は、例えば人体を検出しているときには検出信号を制御手段２８に送信し、人体を検出していないときには信号を発信しない。制御手段２８は、ソレノイドの如き適宜の作動器（図示していない）を介してスイッチ手段１８を開放することができる。   2 and FIG. 2, the illumination means 22 is connected to the plug 16 via a power supply circuit 24, and the switch means 18 is disposed in the power supply circuit 24. . Accordingly, if the plug 16 is connected to a commercial power outlet (not shown) and the switch means 18 is closed, power is supplied to the illumination means 22 and the illumination means 22 is activated or lit. A sub-circuit 26 is attached to the power supply circuit 24, and a control means 28 is connected to the sub-circuit 26 together with the human sensor 20. The control means 28 that can be constituted by a micro computer incorporates a time measuring means 30. For example, the human sensor 20 transmits a detection signal to the control unit 28 when a human body is detected, and does not transmit a signal when a human body is not detected. The control means 28 can open the switch means 18 via a suitable actuator (not shown) such as a solenoid.

図１及び図２と共に図３を参照して、本発明に従って構成された照明装置２の作用を説明すると、次のとおりである。プラグ１６が商用電源のコンセントに接続されている状態において、ステップｎー１においてスイッチ手段１８が手動で閉成されると、照明手段２２に電力が供給されて照明手段２２が作動され机上が照明され、そしてまた人感センサー２０及び制御手段２８にも所要電力が供給される。ステップｎ−２においては、人感センサー２０が人体を検出しているか否かが判別される。人感センサー２０が人体を検出していない時にはステップｎー３に進み、人感センサー２０が人体を検出しなくなってから所定時間、例えば５分間、が経過したか否かが判別される。所定時間を経過していない時はステップｎ−２に戻るが、所定時間を経過するとステップｎ−４に進み、制御手段２８によってスイッチ手段１８が開放される。かくして、照明手段２２が電源から切り離されると共に人感センサー２０及び制御手段２８も電源から切り離され、照明手段２２による不必要な電力消費が回避されると共に、人感センサー２０及び制御手段２８による待機電力消費も回避される。照明手段２２を再び作動せしめるためには、スイッチ手段１８を手動で閉成すればよい。制御手段２８によるスイッチ手段１８の開放に先立って、手動によってスイッチ手段１８を開放し、これによって照明手段２２と共に人感センサー２０及び制御手段２８を電源から切り離すこともできる。   Referring to FIG. 3 together with FIG. 1 and FIG. 2, the operation of the lighting device 2 configured according to the present invention will be described as follows. In the state where the plug 16 is connected to the outlet of the commercial power supply, when the switch means 18 is manually closed in step n-1, power is supplied to the illumination means 22, the illumination means 22 is operated, and the desk is illuminated. The required power is also supplied to the human sensor 20 and the control means 28. In step n-2, it is determined whether or not the human sensor 20 detects a human body. When the human sensor 20 has not detected the human body, the process proceeds to step n-3, and it is determined whether or not a predetermined time, for example, 5 minutes has elapsed since the human sensor 20 no longer detects the human body. When the predetermined time has not elapsed, the process returns to step n-2, but when the predetermined time has elapsed, the process proceeds to step n-4, and the control means 28 opens the switch means 18. Thus, the illumination means 22 is disconnected from the power supply and the human sensor 20 and the control means 28 are also disconnected from the power supply, unnecessary power consumption by the illumination means 22 is avoided, and standby by the human sensor 20 and the control means 28 is avoided. Power consumption is also avoided. In order to activate the illumination means 22 again, the switch means 18 may be manually closed. Prior to the opening of the switch means 18 by the control means 28, the switch means 18 can be manually opened, thereby disconnecting the human sensor 20 and the control means 28 together with the illumination means 22 from the power source.
