Description

本発明は、照明システムに関するものである。   The present invention relates to a lighting system.

従来から、複数のランプを備える照明システムが提供されている（例えば、特許文献１参照）。   Conventionally, an illumination system including a plurality of lamps has been provided (see, for example, Patent Document 1).

従来、照明システムにおいては、いずれかのランプが寿命末期となる度に、寿命末期となったランプを交換していた。
特開２００３−１７２７８号公報 Conventionally, in a lighting system, whenever one of the lamps reaches the end of the life, the lamp at the end of the life is replaced.
JP 2003-17278 A

しかし、常駐している管理者が存在しない場合は、ランプの交換の度に管理者の移動のためのコストや人件費が必要となる。従って、上記のようにランプが寿命末期となる度に交換作業を行うよりも、ランプの寿命よりもやや短い程度の間隔でランプの一斉交換を行うことが望ましいが、ランプの寿命は使用環境や使用形態によっても変動し、ランプ毎のばらつきもあるため、交換時期の判断が難しいという問題があった。   However, if there is no resident manager, the cost and labor costs for moving the manager are required each time the lamp is replaced. Therefore, it is desirable to replace the lamps at intervals slightly shorter than the lamp life rather than to replace the lamp every time the lamp is at the end of life as described above. There is a problem that it is difficult to judge the replacement time because it varies depending on the use form and also varies from lamp to lamp.

本発明は、上記事由に鑑みて為されたものであり、その目的は、ランプの一斉交換を行う時期の目安を与えることができる照明システムを提供することにある。   The present invention has been made in view of the above reasons, and an object of the present invention is to provide an illumination system that can provide an indication of when to perform simultaneous lamp replacement.

Lighting fixtures, timing means provided for each group of lighting fixtures for measuring the cumulative lighting time of the lamps of each lighting fixture belonging to the group, and light for the lamps of the lighting fixtures provided for each lighting fixture are detected. Based on the life rate calculated by the life rate calculating means, the life rate calculating means for calculating the life rate for each group of lighting fixtures, the value indicating that the brightness sensor and the higher the significance of simultaneous replacement of the lamp is, the higher the brightness sensor is. Display means for displaying information indicating when the lamps should be replaced at the same time, and the life rate calculating means uses the cumulative lighting time obtained from the time counting means as the cumulative lighting time. The life rate is obtained by substituting into the life function, which is a monotonically increasing function, and the life rate calculation means detects the proportion of lighting fixtures whose lamps are at the end of their life in the lighting group to the power detection means. The life function coefficient should be changed from time to time for each group of lighting fixtures so that the higher the proportion of lighting fixtures whose lamps are at the end of their life in the group, the higher the lifetime ratio. It is characterized by.

この発明によれば、表示手段に表示される情報により、ランプを一斉交換すべき時期の目安が与えられる。   According to the present invention, the information displayed on the display means gives an indication of when the lamps should be replaced all at once.

The life rate is obtained by substituting it into the life function, which is a monotonically increasing function with respect to the cumulative lighting time. The life rate calculation means detects the proportion of lighting fixtures whose lamps are at the end of their life in the group that is lit. In addition to making a determination based on the power consumption detected by the means, the coefficient of the lifetime function is changed from time to time for each group of lighting fixtures so that the higher the proportion of lighting fixtures whose lamps are at the end of their life in the group, the higher the lifetime ratio. It is characterized by changing.

Further, more appropriate temperature and humidity can be used as compared with the case where a temperature sensor and a humidity sensor common to all groups are used.

請求項１の発明及び請求項２の発明によれば、高いほどランプの一斉交換の意義があることを示す数値である寿命率を照明器具のグループ毎に演算する寿命率演算手段と、寿命率演算手段によって演算された寿命率に基づいて、ランプを一斉交換すべき時期の目安となる情報を表示する表示手段とを備えるので、表示手段に表示される情報により、ランプを交換すべき時期の目安が与えられる。   According to the invention of claim 1 and the invention of claim 2, the life rate calculating means for calculating the life rate, which is a numerical value indicating that the higher the value of simultaneous replacement of the lamp is, for each group of lighting fixtures, the life rate Display means for displaying information that serves as an indication of when lamps should be replaced at the same time on the basis of the life rate calculated by the calculating means.

以下、本発明を実施するための最良の形態について、図面を参照しながら説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

本実施形態はビルにおいて用いられる照明システムであって、図２に示すように、商用電源ＡＣから分電盤Ｂで分配された電力が供給される複数個の照明器具１を備える。   The present embodiment is a lighting system used in a building, and includes a plurality of lighting fixtures 1 to which power distributed by a distribution board B is supplied from a commercial power source AC as shown in FIG.

各照明器具１は、それぞれ光源としてのランプ（図示せず）とランプを点灯する点灯装置（図示せず）とを有する。   Each lighting fixture 1 has a lamp (not shown) as a light source and a lighting device (not shown) for lighting the lamp.

また、照明器具１は、例えば同じ部屋や同じ階など設置場所が互いに近いもの同士を同じグループＧ１〜Ｇ３として複数個のグループＧ１〜Ｇ３に分けられており、グループＧ１〜Ｇ３毎に分電盤Ｂで分配された電力が供給されている。   Moreover, the lighting fixtures 1 are divided into a plurality of groups G1 to G3 as the same groups G1 to G3, for example, in the same room or the same floor, and the distribution boards are divided into groups G1 to G3. The power distributed by B is supplied.

本実施形態においては、各照明器具１はグループＧ１〜Ｇ３毎に設けられた図示しないスイッチによってグループＧ１〜Ｇ３毎に一括してオンオフされ、同一グループＧ１〜Ｇ３内では各照明器具のランプの累積点灯時間が共通となっている。   In this embodiment, each lighting fixture 1 is turned on and off for each group G1 to G3 by a switch (not shown) provided for each group G1 to G3, and the lamps of each lighting fixture are accumulated in the same group G1 to G3. The lighting time is common.

各グループＧ１〜Ｇ３では、それぞれ１個の照明器具１が、通電量を検出する通電検出装置２を介して分電盤Ｂに接続され、他の各照明器具１にはそれぞれ例えば送り配線により電力が供給されている。通電検出装置２はグループＧ１〜Ｇ３毎に設けられてそれぞれ調光手段を兼ねており、各照明器具１に供給する電力を制御して照明器具１の定格電力よりも低くすることにより、定格点灯時の光出力に対する光出力の比（以下、「調光比」と呼ぶ。）をグループＧ１〜Ｇ３内の全ての照明器具１で一括して変更（以下、「調光制御」と呼ぶ。）することが可能となっている。   In each of the groups G1 to G3, one luminaire 1 is connected to the distribution board B via an energization detection device 2 that detects the energization amount, and each of the other luminaires 1 is powered by, for example, a feed wiring. Is supplied. The energization detection device 2 is provided for each of the groups G1 to G3, and also serves as a dimming unit. By controlling the power supplied to each lighting fixture 1 to be lower than the rated power of the lighting fixture 1, the rated lighting is performed. The ratio of the light output to the hourly light output (hereinafter referred to as “light control ratio”) is collectively changed (hereinafter referred to as “light control”) in all the lighting fixtures 1 in the groups G1 to G3. It is possible to do.

また、本実施形態の照明システムは、図１に示すように、高いほど各照明器具１のランプの一斉交換の意義があることを示す数値である寿命率を算出する寿命率演算装置３と、寿命率演算装置３によって算出された寿命率に基づいてランプを一斉交換すべき時期の目安となる情報を表示する表示装置４とを備える。寿命率演算装置３や表示装置４は、照明器具１や通電検出装置２から離れた遠隔地に配置されていてもよい。   In addition, as shown in FIG. 1, the lighting system of the present embodiment has a lifetime ratio calculation device 3 that calculates a lifetime ratio that is a numerical value indicating that the higher the lamp is, the higher the significance of simultaneous replacement of the lamps of each lighting fixture 1. And a display device 4 for displaying information serving as a guideline for when lamps should be replaced at the same time based on the life rate calculated by the life rate calculation device 3. The life rate calculation device 3 and the display device 4 may be arranged in a remote place away from the lighting fixture 1 and the energization detection device 2.

表示装置４は、例えば寿命率を表示するディスプレイであってもよいし、寿命率が所定の閾値を上回ったときにランプの交換を要求する表示灯を点灯させるものであってもよい。または、表示装置４として使用者が所持する携帯電話やパーソナルコンピュータなどの端末器を用い、使用者からの要請に応じて公衆網を通じて上記端末器に寿命率の通知がなされるようにしたり、寿命率が所定の閾値を上回ったときに公衆網を通じて上記端末器にランプの一斉交換の要求がなされるようにしてもよい。   The display device 4 may be, for example, a display that displays a life rate, or may be a device that lights a display lamp that requires lamp replacement when the life rate exceeds a predetermined threshold. Alternatively, a terminal device such as a mobile phone or a personal computer possessed by the user is used as the display device 4 so that the life rate is notified to the terminal device through the public network in response to a request from the user. When the rate exceeds a predetermined threshold, a request for simultaneous lamp replacement may be made to the terminal through the public network.

表示装置４は、寿命率の報知やランプの一斉交換の要求をグループＧ１〜Ｇ３毎に行う。これにより、グループＧ１〜Ｇ３毎に、各照明器具１のランプを一斉交換すべき時期の目安が与えられる。なお、寿命率の平均値が所定の閾値を上回ったときに、表示装置４によって使用者にランプの一斉交換の要求がなされるようにし、全てのグループＧ１〜Ｇ３の照明器具１のランプを一斉交換すべき時期の目安を与えるようにしてもよい。   The display device 4 makes a notification of the life rate and a request for simultaneous replacement of the lamps for each of the groups G1 to G3. Thereby, the standard of the time when the lamp | ramp of each lighting fixture 1 should be replaced simultaneously is given for every group G1-G3. In addition, when the average value of the life rate exceeds a predetermined threshold, the display device 4 requests the user to replace the lamps at the same time, and the lamps of the luminaires 1 of all the groups G1 to G3 are transmitted all at once. You may make it give the standard of the time which should be replaced | exchanged.

以下、本発明の主要部である寿命率演算装置３について具体的に説明する。寿命率演算装置３は不揮発性メモリからなる記憶部（図示せず）を有し、記憶部には累積点灯時間と寿命率との関係を示す寿命関数が予め格納されている。本実施形態における寿命関数は、多数のランプについてそれぞれ連続して定格点灯させた場合における寿命末期に至るまでの累積点灯時間を計測することによって得られたデータを、累積点灯時間を横軸にとり、その累積点灯時間までに寿命末期となるランプの数の全体に占める割合を縦軸に取ったグラフに表し、これを適当な関数にフィッティングして得られるものであって、図３に曲線Ｌ１で示すような、累積点灯時間に対する単調増加関数である。   Hereinafter, the life rate calculator 3 which is the main part of the present invention will be described in detail. The life rate calculation device 3 has a storage unit (not shown) made of a nonvolatile memory, and a life function indicating the relationship between the cumulative lighting time and the life rate is stored in advance in the storage unit. The life function in the present embodiment is the data obtained by measuring the cumulative lighting time until the end of the lifetime when the rated lighting is continuously performed for each of a number of lamps, the cumulative lighting time is taken on the horizontal axis, The ratio of the total number of lamps at the end of the lifetime up to the cumulative lighting time is shown in a graph with the vertical axis taken, and this is obtained by fitting to an appropriate function. It is a monotonically increasing function for the cumulative lighting time as shown.

寿命率演算装置３は、通電検出装置２によって検出された通電量（すなわち各照明器具１における消費電力）に基づいて各照明器具１のランプがオフからオンに切り替わったことを検出してその回数（以下、「点滅回数」と呼ぶ。）を計数するとともに、各照明器具１のランプの累積点灯時間を計時しており、この累積点灯時間を寿命関数に代入することによって寿命率を得るという処理を、グループＧ１〜Ｇ３毎に行う。すなわち、本実施形態における寿命率演算装置３は計時手段でもある。また、本実施形態における寿命率は、ランプのうち寿命末期であるものが占める割合のおおよその期待値である。つまり、寿命率が高いほど寿命末期のランプが多いことを意味し、すなわちランプの一斉交換の意義があるということになる。   The life rate calculation device 3 detects that the lamp of each lighting fixture 1 has been switched from OFF to ON based on the energization amount detected by the energization detection device 2 (that is, the power consumption in each lighting fixture 1). (Hereinafter referred to as “the number of blinks”), and the cumulative lighting time of the lamps of each lighting fixture 1 is counted, and the lifetime ratio is obtained by substituting this cumulative lighting time into the lifetime function. Is performed for each of the groups G1 to G3. That is, the life rate calculation device 3 in this embodiment is also a time measuring means. The life rate in the present embodiment is an approximate expected value of the proportion of lamps that are at the end of their life. In other words, the higher the lifetime ratio, the more lamps at the end of the lifetime, that is, the significance of simultaneous lamp replacement.

ここで、ランプの寿命は使用状況によって異なる。具体的には、低い調光比で長時間点灯するほどランプの寿命は長くなり、逆に、点滅回数が多いほどランプの寿命は短くなる。さらに、極端に高い温度や極端に低い温度の環境下でのオンオフ並びに点灯を行うと、その点滅回数や点灯時間に応じてランプの寿命はより短くなる。そこで、本実施形態の寿命率演算装置３は、グループＧ１〜Ｇ３毎に、上記使用状況を判断して寿命関数の係数を随時変更する。   Here, the lifetime of the lamp varies depending on the use situation. Specifically, the longer the lamp is lit at a low dimming ratio, the longer the lamp life is. Conversely, the more the number of blinks is, the shorter the lamp life is. Further, when the lamp is turned on / off and turned on in an environment of extremely high temperature or extremely low temperature, the life of the lamp is shortened according to the number of blinks and the lighting time. Therefore, the life rate calculation device 3 according to the present embodiment determines the use status for each of the groups G1 to G3 and changes the coefficient of the life function as needed.

具体的に説明すると、本実施形態は、周囲の温度（気温）を検出する温度センサ５と、周囲の湿度を検出する湿度センサ６とを、それぞれグループＧ１〜Ｇ３毎に備える。温度センサ５と湿度センサ６とは、対応するグループＧ１〜Ｇ３の各照明器具１と温度や湿度の条件が揃えられるように、それぞれ例えば対応するグループＧ１〜Ｇ３の各照明器具１と同じ階や部屋など、対応するグループＧ１〜Ｇ３の各照明器具１の近くに配置することが望ましい。温度センサ５及び湿度センサ６はそれぞれ周知の技術で実現可能であるので、詳細な説明は省略する。   More specifically, the present embodiment includes a temperature sensor 5 that detects the ambient temperature (air temperature) and a humidity sensor 6 that detects the ambient humidity for each of the groups G1 to G3. For example, the temperature sensor 5 and the humidity sensor 6 have the same floors as the corresponding lighting fixtures 1 of the corresponding groups G1 to G3, respectively, so that the temperature and humidity conditions are aligned with the lighting fixtures 1 of the corresponding groups G1 to G3. It is desirable to arrange it near each lighting fixture 1 of corresponding groups G1-G3, such as a room. Since the temperature sensor 5 and the humidity sensor 6 can be realized by a well-known technique, detailed description thereof is omitted.

寿命率演算器３は、各照明器具１の点滅回数が多いほど、また、温度センサ５によって検出された温度が所定の範囲を外れている期間や湿度センサ６によって検出された湿度が所定の範囲を外れている期間内での点滅回数が多いほど、また、温度センサ５によって検出された温度が所定の範囲を外れている期間や湿度センサ６によって検出された湿度が所定の範囲を外れている期間に各照明器具１のランプがそれぞれ点灯された時間が長いほど、それぞれ寿命率を高くする方向に、寿命関数の係数を変更する。温度に関し、上記所定の範囲は例えば１５℃〜３５℃とする。   The life rate calculator 3 increases the number of times each lighting fixture 1 blinks, and the period when the temperature detected by the temperature sensor 5 is out of the predetermined range and the humidity detected by the humidity sensor 6 are within the predetermined range. The more the number of blinks in the period outside the range, the more the temperature detected by the temperature sensor 5 is outside the predetermined range and the humidity detected by the humidity sensor 6 is out of the predetermined range. The longer the time during which the lamps of the respective lighting fixtures 1 are lit during the period, the longer the lifetime ratio is changed, the coefficient of the lifetime function is changed. Regarding the temperature, the predetermined range is, for example, 15 ° C to 35 ° C.

また、寿命率演算装置３は、各照明器具１がそれぞれ１００％未満の調光比で点灯（以下、「調光点灯」と呼ぶ。）されている期間について、調光比が低いほど、また調光点灯されている時間が長いほど、それぞれ寿命率を低くする方向に、寿命関数の係数を変更する。   Further, the lifetime ratio calculation device 3 is configured such that the lower the dimming ratio is, the more the lighting device 1 is lit at a dimming ratio of less than 100% (hereinafter referred to as “dimming lighting”). The longer the time during which the light is lit, the longer the life ratio is changed, the coefficient of the life function is changed.

さらに、本実施形態では、各照明器具１に、それぞれランプの明るさを検出する明るさセンサ１１が設けられている。寿命率演算装置３は、点灯中のグループＧ１〜Ｇ３においていずれかの照明器具１で明るさセンサ１１の出力が所定の点灯閾値を下回っていたときに、その照明器具１のランプが寿命末期であると判定する。また、寿命率演算装置３の記憶部には、予めグループＧ１〜Ｇ３毎の照明器具１の個数が格納されている。そして、寿命率演算装置３は、グループＧ１〜Ｇ３毎に、ランプが寿命末期と判定された照明器具１が占める割合（以下、「寿命末期率」と呼ぶ。）を算出して寿命率と比較し、寿命率を寿命末期率に近づけるように寿命関数の係数を変更する。すなわち、寿命末期率が寿命率よりも低ければ図４に曲線Ｌ２で示すように寿命率を高くするように寿命関数の係数を変更し、寿命末期率が寿命率よりも高ければ寿命率を低くするように寿命関数の係数を変更する。   Furthermore, in this embodiment, each luminaire 1 is provided with a brightness sensor 11 that detects the brightness of the lamp. When the output of the brightness sensor 11 is lower than a predetermined lighting threshold value in any lighting fixture 1 in the lighting groups G1 to G3, the lifetime ratio calculating device 3 has the lamp of the lighting fixture 1 at the end of life. Judge that there is. Moreover, the number of the lighting fixtures 1 for each of the groups G1 to G3 is stored in the storage unit of the life rate calculation device 3 in advance. Then, the life rate calculation device 3 calculates the ratio (hereinafter referred to as “life end life rate”) of the lighting fixture 1 in which the lamp is determined to be at the end of life for each of the groups G1 to G3 and compares it with the life rate. Then, the coefficient of the life function is changed so that the life rate approaches the end-of-life rate. That is, if the end-of-life rate is lower than the life rate, the coefficient of the life function is changed to increase the life rate as shown by the curve L2 in FIG. 4, and if the end-of-life rate is higher than the life rate, the life rate is lowered. Change the coefficient of the life function so that

寿命率が高くなるように寿命関数の係数を変更する具体的な方法としては、例えば、寿命関数全体に１より大きい定数を乗じる（つまり、全ての係数を定数倍する）ことや、寿命関数の定数項（つまり、０次の項の係数）を加算することが考えられる。逆に、寿命率が低くなるように寿命関数の係数を変更するには、寿命関数全体に１より小さい正の定数を乗じることが考えられる。寿命関数の係数を変更する各場合について、寿命関数の係数に乗じる数や加算する数と、点滅回数や点灯時間や調光比との適切な関係式は、照明器具１のランプの形態や点灯装置の回路構成等によって異なり、例えば実験によって求めればよい。   As a specific method of changing the coefficient of the life function so as to increase the life ratio, for example, the whole life function is multiplied by a constant larger than 1 (that is, all coefficients are multiplied by a constant), It is conceivable to add a constant term (that is, a coefficient of a 0th-order term). Conversely, in order to change the coefficient of the life function so that the life ratio is low, it is conceivable to multiply the whole life function by a positive constant smaller than 1. For each case where the coefficient of the life function is changed, an appropriate relational expression between the number multiplied by the coefficient of the life function or the number to be added and the number of times of blinking, lighting time, and dimming ratio is the form of the lamp of the lighting fixture 1 or lighting It depends on the circuit configuration of the apparatus, and may be obtained, for example, by experiments.

寿命率演算装置３が寿命関数の係数を変更するタイミングとしては、各照明器具１のランプのオンオフや調光比の変更といったトリガが与えられる度に寿命関数の係数を変更するようにしてもよいし、図５に示すような点灯条件（調光比や温度・湿度）やランプ残存率（１００−寿命末期率）や点滅回数や累積点灯時間の履歴を蓄積して所定の更新時間（例えば６ヶ月）毎に定期的に寿命関数の係数を変更するようにしてもよい。   As the timing at which the life rate calculating device 3 changes the coefficient of the life function, the coefficient of the life function may be changed every time a trigger such as turning on / off the lamp of each lighting fixture 1 or changing the dimming ratio is given. Then, a lighting condition (dimming ratio, temperature / humidity), lamp remaining rate (100-end-of-life rate), number of blinks, and cumulative lighting time history as shown in FIG. The coefficient of the life function may be changed periodically every month).

上記構成によれば、表示装置４に表示される情報により、各照明器具１のランプを一斉交換すべき時期の目安が与えられる。   According to the above configuration, the information displayed on the display device 4 gives an indication of when the lamps of the respective lighting fixtures 1 should be replaced at once.

なお、各照明器具１にそれぞれ明るさセンサ１１を設ける代わりに、いずれかのグループＧ１〜Ｇ３において照明器具１のランプが点灯しているときに、寿命率演算装置３が、該グループＧ１〜Ｇ３の通電検出装置２において検出された通電量と調光比とに基づいて、該グループＧ１〜Ｇ３においてランプが寿命末期である照明器具１の占める割合を算出するようにしてもよい。   Instead of providing the brightness sensor 11 for each luminaire 1, when the lamp of the luminaire 1 is lit in any of the groups G1 to G3, the lifetime ratio calculating device 3 operates the groups G1 to G3. On the basis of the energization amount and the dimming ratio detected by the energization detection device 2, the proportion of the luminaire 1 whose lamps are at the end of their life in the groups G1 to G3 may be calculated.

また、温度センサ５や湿度センサ６としては全てのグループＧ１〜Ｇ３で共通のものを用いることもできるが、本実施形態のようにグループＧ１〜Ｇ３毎にそれぞれ該グループＧ１〜Ｇ３の各照明器具１の近く（例えば同じ部屋や階）に温度センサ５や湿度センサ６を設け、いずれかのグループＧ１〜Ｇ３の寿命関数の変更に当っては該グループと同じ部屋や階に設けられた温度センサ５や湿度センサ６を用いるようにしたほうが、より正確な温度や湿度を用いることができるから望ましい。   The temperature sensor 5 and the humidity sensor 6 may be the same for all the groups G1 to G3, but each lighting device of each of the groups G1 to G3 is used for each group G1 to G3 as in this embodiment. A temperature sensor 5 and a humidity sensor 6 are provided near 1 (for example, the same room or floor), and when changing the life function of any of the groups G1 to G3, a temperature sensor provided in the same room or floor as the group 5 and the humidity sensor 6 are preferable because more accurate temperature and humidity can be used.
