Description

本発明は、ＬＥＤ照明装置に備えられた電解コンデンサの寿命を推定するＬＥＤ照明装置の寿命推定装置に関する。   The present invention relates to a lifetime estimation device for an LED illumination device that estimates the lifetime of an electrolytic capacitor provided in the LED illumination device.

近年、省エネルギー対策として蛍光灯に代わり球切れが無いＬＥＤ照明が適用されるようになって来ている。しかし昨今、ＬＥＤ照明装置の電源装置に含まれる電解コンデンサの寿命によるＬＥＤ照明装置の故障が問題となっている。電解コンデンサの寿命を推定する技術として従来、特許文献１に開示された技術が知られている。この従来技術は、電圧測定回路で照明装置の電源装置に含まれている電解コンデンサの放電時の電圧を測定し、測定した電圧から電解コンデンサの寿命を判定するようにしたものである。   In recent years, as an energy saving measure, LED lighting without a broken bulb has been applied instead of a fluorescent lamp. However, recently, failure of the LED lighting device due to the life of the electrolytic capacitor included in the power supply device of the LED lighting device has become a problem. Conventionally, a technique disclosed in Patent Document 1 is known as a technique for estimating the life of an electrolytic capacitor.

特許文献１に開示された従来技術を、ＬＥＤ照明装置の寿命予測に適用することが考えられる。しかしこのように従来技術を適用したものでは、ＬＥＤ照明装置の寿命が来てからＬＥＤ照明装置を交換することになる。すなわち寿命が来てからＬＥＤ照明装置の交換のための準備作業が始まることから、ＬＥＤ照明装置の交換作業の能率向上を見込めない。また、ＬＥＤ照明装置の寿命による故障発生のときからＬＥＤ照明装置を新たに交換するまでの間、ＬＥＤ照明装置の設置場所は消灯状態となることから、ＬＥＤ照明装置の利用者に長時間にわたって不便をかけることになる。   It is conceivable to apply the conventional technique disclosed in Patent Document 1 to the lifetime prediction of an LED lighting device. However, in the case where the conventional technology is applied in this way, the LED lighting device is replaced after the lifetime of the LED lighting device comes. That is, since the preparation work for replacing the LED lighting device starts after the end of its life, the efficiency of the replacement work of the LED lighting device cannot be expected. In addition, since the installation location of the LED lighting device is turned off from the time of the failure due to the life of the LED lighting device until the replacement of the LED lighting device, it is inconvenient for a long time for the user of the LED lighting device.

本発明に係るＬＥＤ照明装置の寿命推定装置によれば、ＬＥＤ照明装置の交換作業の能率を従来よりも向上させることができる。例えば、ＬＥＤ照明装置の交換に際してのＬＥＤ照明装置の消灯状態を従来よりも短い時間で解消させることができ、ＬＥＤ照明装置の利用者に対するサービス性を向上させることができる。前述した以外の課題、構成及び効果は、以下の実施形態の説明により明らかにされる。   According to the LED lighting device lifetime estimating apparatus according to the present invention, the efficiency of the replacement work of the LED lighting device can be improved as compared with the related art. For example, the turn-off state of the LED lighting device when replacing the LED lighting device can be eliminated in a shorter time than before, and the serviceability for the user of the LED lighting device can be improved.

図１に示すように、本実施形態に係るＬＥＤ照明装置の寿命推定装置の一実施形態が備えられたエレベーター装置は、昇降路内を昇降する乗りかご１と、この乗りかご１に主ロープ２によって連結されて重量バランスを確保する釣り合いおもり３とを備えている。また、昇降路の天井部に配置された機械室内には、主ロープ２を移動させるシーブ４ａと、このシーブ４ａを回転させるモータ４ｂとを含む巻上機４を備えている。   As shown in FIG. 1, an elevator apparatus provided with an embodiment of a life estimation device for an LED lighting device according to the present embodiment includes a car 1 that moves up and down in a hoistway, and a main rope 2 attached to the car 1.

乗りかご１には、この乗りかご１に備えられた機器に対する信号の送受信に活用されるテールコード５が接続されており、巻上機４にはこの巻上機４の駆動を制御する制御信号が送信される信号線６が接続されている。テールコード５及び信号線６は、乗りかご１の運行を制御する制御装置７に接続されている。また、乗りかご１と釣り合いおもり３を互いに離隔させるそらせ車８と、制御装置７に電力を供給する電源９とが備えられている。   The car 1 is connected to a tail cord 5 that is used for transmission / reception of signals to / from the equipment provided in the car 1, and the hoisting machine 4 has a control signal for controlling the driving of the hoisting machine 4. Is connected to the signal line 6. The tail cord 5 and the signal line 6 are connected to a control device 7 that controls the operation of the car 1. Further, a deflecting wheel 8 for separating the car 1 and the counterweight 3 from each other and a power source 9 for supplying electric power to the control device 7 are provided.

図２に示すように、乗りかご１内には、この乗りかご１内を照明するＬＥＤを有するＬＥＤ照明装置１０と、乗りかご１内を撮影するカメラ１１とが備えられている。カメラ１１によってＬＥＤ照明装置１０の点灯状態が撮影され、このカメラ１１によって撮影された映像は前述の制御装置７に送信される。   As shown in FIG. 2, the car 1 is provided with an LED illumination device 10 having an LED for illuminating the car 1 and a camera 11 for photographing the car 1. The lighting state of the LED illumination device 10 is photographed by the camera 11, and the image photographed by the camera 11 is transmitted to the control device 7 described above.

図３に示すように、ＬＥＤ照明装置１０は、電源９に接続された電源装置１７を備えており、この電源装置１７には本実施形態の寿命推定対象である電解コンデンサ１６が含まれている。   As shown in FIG. 3, the LED lighting device 10 includes a power supply device 17 connected to a power supply 9, and the power supply device 17 includes an electrolytic capacitor 16 that is a life estimation target of the present embodiment. .

同図３に示すように、本実施形態に係るＬＥＤ照明装置の寿命推定装置は、電解コンデンサ１６の通電時間を積算する通電時間計測部１８ａと、電解コンデンサ１６の寿命時間に至る前の時間が予め交換時間閾値として設定され、通電時間計測部１８ａで積算された通電時間が、交換時間閾値に至ったか否か判定する寿命判定部１８ｂとを備えている。   As shown in FIG. 3, the lifetime estimation device for the LED lighting device according to the present embodiment includes an energization time measurement unit 18 a that integrates the energization time of the electrolytic capacitor 16, and the time before the lifetime of the electrolytic capacitor 16 is reached. It includes a life determination unit 18b that is set in advance as a replacement time threshold and determines whether or not the energization time accumulated by the energization time measurement unit 18a has reached the replacement time threshold.

また、寿命判定部１８ｂで通電時間計測部１８ａで積算された通電時間が、交換時間閾値に至ったと判定されたとき、点灯状態を変更させる電流をＬＥＤ１５に供給する制御を行う供給電流制御部１８ｃを備えている。さらに本実施形態は、寿命判定部１８ｂの判定結果、及び通電時間計測部１８ａで積算された通電時間を、ＬＥＤ照明装置１０から送信する送信部１８ｄを備えている。   In addition, when it is determined that the energization time accumulated in the energization time measurement unit 18a has reached the replacement time threshold value in the life determination unit 18b, a supply current control unit 18c that performs control to supply a current for changing the lighting state to the LED 15 It has. Furthermore, this embodiment is provided with the transmission part 18d which transmits the determination result of the lifetime determination part 18b, and the energization time integrated | accumulated by the energization time measurement part 18a from the LED lighting apparatus 10. FIG.

ＬＥＤ照明装置１０の電源装置１７とＬＥＤ１５の間には、寿命予測装置１８が備えられており、この寿命予測装置１８は、前述した通電時間計測部１８ａと、寿命判定部１８ｂと、供給電流制御部１８ｃと、送信部１８ｄとを含んでいる。   A life prediction device 18 is provided between the power supply device 17 and the LED 15 of the LED lighting device 10, and this life prediction device 18 includes the above-described energization time measurement unit 18a, life determination unit 18b, and supply current control. A unit 18c and a transmission unit 18d are included.

寿命予測装置１８の供給電流制御部１８ｃは、電流値が大きい値と小さい値の連続的な繰り返しとなるようにＬＥＤ１５に供給される電流を制御するものから成る。この供給電流制御部１８ｄｃよってＬＥＤ１５に供給される電流が制御された際には、蛍光灯が寿命に至ったときのようにＬＥＤ照明装置１０のＬＥＤ１５は「ちらついた照明」となる。   The supply current control unit 18c of the life prediction apparatus 18 is configured to control the current supplied to the LED 15 so that the current value is continuously repeated between a large value and a small value. When the current supplied to the LED 15 is controlled by the supply current control unit 18dc, the LED 15 of the LED lighting device 10 becomes “flicker illumination” as when the fluorescent lamp reaches the end of its life.

同図３に示すように本実施形態は、電解コンデンサ１６が設置された環境の温度を検知する温度センサ２０を備えており、前述した交換時間閾値は、温度センサ２０で検知された電解コンデンサ１６が設置された環境の温度に基づいて設定されている。すなわち、寿命判定部１８ｂには、アレニウスの法則による温度と電解コンデンサ１６の寿命時間の関係を示す関数関係が記憶されており、この関数関係と温度センサ２０で検知された環境の温度とにより、電解コンデンサ１６の寿命時間が演算される。このように演算された寿命時間に基づいて交換時間閾値が設定されている。   As shown in FIG. 3, the present embodiment includes a temperature sensor 20 that detects the temperature of the environment in which the electrolytic capacitor 16 is installed, and the above-described replacement time threshold is the electrolytic capacitor 16 detected by the temperature sensor 20. Is set based on the temperature of the installed environment. That is, the life determination unit 18b stores a functional relationship indicating the relationship between the temperature according to Arrhenius's law and the lifetime of the electrolytic capacitor 16, and by this functional relationship and the temperature of the environment detected by the temperature sensor 20, The lifetime of the electrolytic capacitor 16 is calculated. The replacement time threshold is set based on the lifetime calculated in this way.

図４は、アレニウスの法則による温度と電解コンデンサ１６の寿命時間との関係の参考例を示しているが、アレニウスの法則によれば同図４の下段側に示された８５℃保証のアルミ電解コンデンサの場合には、８５℃で２０００時間の寿命時間を有するが、８５℃よりも１０℃上昇し９５℃となっている環境温度では、寿命時間が１／２の１０００時間となる。また、同図４の上段側に示された１０５℃保証のアルミ電解コンデンサの場合には、８５℃で８０００時間の寿命を有するが、９５℃の環境温度では１／２の４０００時間となる。このように温度センサ２０で検知された温度に応じて電解コンデンサ１６の寿命が変化することが一般に知られている。したがって、電解コンデンサ１６が設置された環境温度を温度センサ２０で検知することにより、その環境温度下で設置されている電解コンデンサ１６の寿命時間を演算することができる。この演算された寿命時間に基づいて、寿命時間に至る前の前述した交換時間閾値を精度良く設定することができる。   FIG. 4 shows a reference example of the relationship between the temperature according to the Arrhenius law and the lifetime of the electrolytic capacitor 16. According to the Arrhenius law, the aluminum electrolysis with 85 ° C. guarantee shown on the lower side of FIG. In the case of a capacitor, it has a lifetime of 2000 hours at 85 ° C., but at an environmental temperature that is 10 ° C. higher than 85 ° C. and is 95 ° C., the lifetime is ½, 1000 hours. In addition, the 105 ° C. guaranteed aluminum electrolytic capacitor shown on the upper side of FIG. 4 has a lifetime of 8000 hours at 85 ° C., but it is ½ of 4000 hours at an ambient temperature of 95 ° C. As described above, it is generally known that the life of the electrolytic capacitor 16 changes according to the temperature detected by the temperature sensor 20. Therefore, by detecting the environmental temperature at which the electrolytic capacitor 16 is installed by the temperature sensor 20, the lifetime of the electrolytic capacitor 16 installed at the environmental temperature can be calculated. Based on the calculated lifetime, the above-described replacement time threshold before reaching the lifetime can be set with high accuracy.

図３及び図５に示すように、本実施形態は、寿命予測装置１８の送信部１８ｄから送信された寿命判定部１８ｂの判定結果、通電時間計測部１８ａで積算された通電時間、及び温度センサ２０で検知された電解コンデンサ１６の環境温度を、ＬＥＤ照明装置１０の外部に設けられた遠隔監視施設、例えば図１に示したエレベーター装置を含めて複数のエレベーター装置の稼動状態を遠隔的に監視する管制センター３２に送信する後述の外部送信装置を備えている。   As shown in FIG. 3 and FIG. 5, in the present embodiment, the determination result of the life determination unit 18 b transmitted from the transmission unit 18 d of the life prediction device 18, the energization time accumulated by the energization time measurement unit 18 a, and the temperature sensor The environmental temperature of the electrolytic capacitor 16 detected at 20 is remotely monitored from the remote monitoring facility provided outside the LED lighting device 10, for example, the operating state of a plurality of elevator devices including the elevator device shown in FIG. And an external transmission device to be described later for transmitting to the control center 32.

また、本実施形態は、図３に示すようにＬＥＤ照明装置１０を流れる電流の値を検知する電流センサ２１を備え、後述の外部送信装置は、電流センサ２１で検知された値を、寿命予測装置１８の送信部１８ｄから送信された寿命判定部１８ｂの判定結果、及び通電時間計測部１８ａで積算された通電時間と共に管制センター３２に送信する処理を行う。   Further, as shown in FIG. 3, the present embodiment includes a current sensor 21 that detects the value of the current flowing through the LED lighting device 10, and the external transmission device described later uses the value detected by the current sensor 21 to predict the lifetime. The process of transmitting to the control center 32 together with the determination result of the life determination unit 18b transmitted from the transmission unit 18d of the apparatus 18 and the energization time accumulated by the energization time measurement unit 18a is performed.

また、後述の外部送信装置は、乗りかご１内の映像、すなわち乗りかご１内のＬＥＤ照明装置１０の点灯状態を撮影する前述のカメラ１１の映像を、寿命予測装置１８の送信部１８ｄから送信された寿命判定部１８ｂの判定結果、及び通電時間計測部１８ａで積算された通電時間と共に管制センター３２に送信する処理を行う。   The external transmission device to be described later transmits a video in the car 1, that is, a video of the above-described camera 11 that captures the lighting state of the LED lighting device 10 in the car 1 from the transmission unit 18d of the life prediction device 18. The process of transmitting to the control center 32 together with the determination result of the life determination unit 18b and the energization time accumulated by the energization time measurement unit 18a is performed.

図５に示すように、ＬＥＤ照明装置１０の寿命予測装置１８は前述した制御装置７に接続されており、制御装置７は、送信部１８ｄを介して、寿命判定部１８ｂの判定結果と、通電時間計測部１８ａで積算された通電時間と、温度センサ２０で検知された電解コンデンサ１６の環境温度を受信する。また制御装置７は電流センサ２１で検知された電流の値と、カメラ１１の映像を受信する。   As shown in FIG. 5, the lifetime prediction device 18 of the LED lighting device 10 is connected to the control device 7 described above, and the control device 7 and the energization result of the lifetime determination unit 18 b via the transmission unit 18 d. The energization time accumulated by the time measuring unit 18a and the environmental temperature of the electrolytic capacitor 16 detected by the temperature sensor 20 are received. Further, the control device 7 receives the value of the current detected by the current sensor 21 and the video of the camera 11.

制御装置７には、エレベーター装置の状況を監視する監視装置３０が接続されており、監視装置３０は通信回線３１を介して管制センター３２に接続されている。制御装置７と監視装置３０とによって、前述した外部送信装置が構成されている。   A monitoring device 30 that monitors the status of the elevator device is connected to the control device 7, and the monitoring device 30 is connected to the control center 32 via a communication line 31. The control device 7 and the monitoring device 30 constitute the aforementioned external transmission device.

制御装置７及び監視装置３０と、通信回線３１を介して、寿命予測装置１８の寿命判定部１８ｂの判定結果と、通電時間計測部１８ａで積算された通電時間と、温度センサ２０で検知された電解コンデンサ１６の環境温度と、電流センサ２１で検知されたＬＥＤ照明装置１０を流れる電流の値と、カメラ１１で撮影された乗りかご１内の映像、すなわちＬＥＤ照明装置１０の点灯状態の映像が、管制センター３２に送信される。   The determination result of the life determination unit 18b of the life prediction device 18, the energization time accumulated by the energization time measurement unit 18a, and the temperature sensor 20 are detected via the control device 7 and the monitoring device 30 and the communication line 31.

また、同図５に示すように、管制センター３２から寿命判定部１８ｂの判定結果、通電時間計測部１８ａで積算された通電時間、及び温度センサ２０で検知された電解コンデンサ１６の環境温度のうちの少なくとも寿命判定部１８ｂの判定結果が送信される保守端末３３を備えている。この保守端末３３は、ＬＥＤ照明装置１０の点検作業、交換作業を行う保守作業員によって保持されている。   Further, as shown in FIG. 5, out of the determination result of the life determination unit 18 b from the control center 32, the energization time accumulated by the energization time measurement unit 18 a, and the environmental temperature of the electrolytic capacitor 16 detected by the temperature sensor 20. The maintenance terminal 33 to which the determination result of at least the life determination unit 18b is transmitted is provided. The maintenance terminal 33 is held by a maintenance worker who performs inspection work and replacement work on the LED lighting device 10.

なお、前述した寿命予測装置１８の寿命判定部１８ｂで設定される交換時間閾値は、新たなＬＥＤ照明装置１０の取り寄せに要する準備時間とか、保守作業員がＬＥＤ照明装置１０の交換現場まで行くに要する時間等を考慮して設定される。   In addition, the replacement time threshold set by the life determination unit 18b of the life prediction device 18 described above is the preparation time required for obtaining a new LED lighting device 10, or the maintenance worker goes to the replacement site of the LED lighting device 10. It is set in consideration of the time required.

このように構成した本実施形態に係るＬＥＤ照明装置の寿命推定装置の処理動作について、図６に基づいて説明する。   The processing operation of the lifetime estimation device for the LED lighting device according to this embodiment configured as described above will be described with reference to FIG.

［手順Ｓ１］ 今仮に、ＬＥＤ照明装置１０の電源装置１７に含まれた電解コンデンサ１６が図４の上段側に示された１０５℃保証のアルミ電解コンデンサであって、寿命時間が８０００時間であり、電解コンデンサ１６の環境温度が温度センサ２０によって９５℃と検知されたものとすると、アレニウスの法則に基づいて寿命判定部１８ｂで演算された寿命時間は４０００時間となる。また、新たなＬＥＤ照明装置１０の入手の準備に要する時間と、保守作業員がＬＥＤ照明装置１０が備えられたエレベーター装置まで出かけて行くに要する時間などを含めた準備時間が例えば１００時間であったとすると、交換時間閾値は、
４０００−１００＝３９００（時間）
となる。この３９００時間が寿命判定部１８ｂに交換時間閾値として設定される。 [Procedure S1] Temporarily, the electrolytic capacitor 16 included in the power supply device 17 of the LED lighting device 10 is the aluminum electrolytic capacitor guaranteed at 105 ° C. shown in the upper side of FIG. 4 and has a lifetime of 8000 hours. Assuming that the environmental temperature of the electrolytic capacitor 16 is detected as 95 ° C. by the temperature sensor 20, the lifetime calculated by the lifetime determination unit 18b based on Arrhenius' law is 4000 hours. In addition, the preparation time including the time required for obtaining a new LED lighting device 10 and the time required for a maintenance worker to go to the elevator apparatus equipped with the LED lighting device 10 is, for example, 100 hours. Assuming that the replacement time threshold is
4000-100 = 3900 (hours)
It becomes. This 3900 hours is set as the replacement time threshold value in the life determination unit 18b.

［手順Ｓ２］ 寿命判定部１８ｂで、通電時間計測部１８ａで積算された寿命時間が３９００時間に至ったか否か判定される。積算された寿命時間が３９００時間に至っていないと判定されたときには、手順Ｓ１に戻る。積算された寿命時間が３９００時間に至ったと判定されたときには、手順Ｓ３に移る。 [Procedure S2] The life determination unit 18b determines whether the life time accumulated by the energization time measurement unit 18a has reached 3900 hours. When it is determined that the accumulated lifetime has not reached 3900 hours, the process returns to step S1. When it is determined that the accumulated lifetime has reached 3900 hours, the process proceeds to step S3.

［手順Ｓ３］ 寿命予測装置１８は、寿命判定部１８ｂの判定結果と、通電時間計測部１８ａで積算された通電時間（３９００時間）と、温度センサ２０で検知された電解コンデンサ１６の環境温度（９５℃）とを送信部１８ｄを介して制御装置７に送信する。同時に寿命判定部１８ｂの判定結果に応じて供給電流制御部１８ｃは、点灯状態を変更させる電流をＬＥＤ１５に供給する制御を行う。これによりＬＥＤ照明装置１０は、ちらついた点灯状態となる。乗りかご１の乗客はＬＥＤ照明装置１０がちらつく照明となったことを目視できる。また、乗りかご１内を撮影するカメラ１１は、乗りかご１内の照明がちらつく映像を制御装置７に送信する。また、電流センサ２１は連続的に変化する状態になった電流値を制御装置７に送信する。 [Procedure S3] The life prediction apparatus 18 includes the determination result of the life determination unit 18b, the energization time accumulated by the energization time measurement unit 18a (3900 hours), and the environmental temperature of the electrolytic capacitor 16 detected by the temperature sensor 20 ( 95 ° C.) is transmitted to the control device 7 via the transmitter 18d. At the same time, the supply current control unit 18c performs control for supplying the LED 15 with a current for changing the lighting state in accordance with the determination result of the life determination unit 18b. Thereby, the LED lighting apparatus 10 will be in the flickering lighting state. Passengers in the car 1 can see that the LED lighting device 10 has flickering lighting. In addition, the camera 11 that captures the inside of the car 1 transmits an image in which the lighting in the car 1 flickers to the control device 7. In addition, the current sensor 21 transmits the current value that has been changed continuously to the control device 7.

制御装置７に送信された寿命判定部１８ｂの判定結果、すなわちＬＥＤ照明装置１０の交換を要する時期に至った旨の判定結果と、通電時間計測部１８ａで積算された通電時間（３９００時間）と、温度センサ２０で検知された電解コンデンサ１６の環境温度（９５℃）と、電流センサ２１で検知された電流値と、カメラ１１の映像とが、監視装置３０、通信回線３１を介して管制センター３２に送信される。管制センター３２は、これらの情報を総合的に確認してＬＥＤ照明装置１０が交換時期に至ったと認識し、保守作業員の所持する保守端末３３に、例えば寿命判定部１８ｂの判定結果と、ＬＥＤ照明装置１０の交換指令を送信する。   The determination result of the life determination unit 18b transmitted to the control device 7, that is, the determination result indicating that the time required to replace the LED lighting device 10, and the energization time (3900 hours) accumulated by the energization time measurement unit 18a, The environmental temperature (95 ° C.) of the electrolytic capacitor 16 detected by the temperature sensor 20, the current value detected by the current sensor 21, and the image of the camera 11 are connected to the control center via the monitoring device 30 and the communication line 31. 32. The control center 32 comprehensively confirms the information and recognizes that the LED lighting device 10 has reached the replacement time. For example, the control center 32 holds the determination result of the life determination unit 18b and the LED on the maintenance terminal 33 owned by the maintenance worker. An exchange command for the illumination device 10 is transmitted.

管制センター３２からの交換指令が送信された保守端末３３を所持する保守作業員は、新たなＬＥＤ照明装置１０の入手後、その新たなＬＥＤ照明装置１０を該当するエレベーター装置のＬＥＤ照明装置１０の設置場所まで運搬する。   The maintenance worker who has the maintenance terminal 33 to which the exchange command from the control center 32 is transmitted obtains the new LED lighting device 10 and then uses the new LED lighting device 10 of the corresponding LED lighting device 10 of the elevator device. Transport to installation location.

ＬＥＤ照明装置１０が設置された乗りかご１内において、該当するＬＥＤ照明装置１０の状態が図７に示すように、保守作業員によって調査される。以下、図７のフローチャートについて説明する。   In the car 1 in which the LED lighting device 10 is installed, the state of the corresponding LED lighting device 10 is investigated by a maintenance worker as shown in FIG. Hereinafter, the flowchart of FIG. 7 will be described.

［手順Ｓ１１］ 保守作業員によってＬＥＤ照明装置１０に備えられているＬＥＤ１５が寿命に至っているか否か確認される。ＬＥＤ１５が寿命に至っていないときには手順Ｓ１２に移り、ＬＥＤ１５が寿命に至っているときには手順Ｓ１３に移る。 [Procedure S11] A maintenance worker checks whether the LED 15 provided in the LED lighting device 10 has reached the end of its life. When the LED 15 has not reached the end of the life, the process proceeds to step S12, and when the LED 15 has reached the end of the life, the process proceeds to step S13.

［手順Ｓ１２］ それまで設置されていたＬＥＤ照明装置１０を新たなＬＥＤ照明装置１０に交換する際に、ＬＥＤ１５については今まで設置されていたＬＥＤ照明装置１０のものを再使用する。 [Procedure S12] When the LED illumination device 10 that has been installed so far is replaced with a new LED illumination device 10, the LED 15 that has been installed so far is reused.

［手順Ｓ１３］ ＬＥＤ１５も含めてＬＥＤ照明装置１０の全体を、新たなＬＥＤ照明装置１０に交換する。 [Procedure S13] The entire LED illumination device 10 including the LED 15 is replaced with a new LED illumination device 10.

このようにして、ＬＥＤ照明装置１０の交換を行うことにより、ＬＥＤ１５が寿命に至っていない場合にはそのＬＥＤ１５を有効に活用し、ＬＥＤ照明装置１０の交換作業に伴う廃棄物を少なくすることができる。   Thus, by exchanging the LED lighting device 10, when the LED 15 has not reached the end of its life, the LED 15 can be used effectively, and waste associated with the replacement work of the LED lighting device 10 can be reduced. .

以上のように構成した本実施形態に係るＬＥＤ照明装置の寿命推定装置によれば、ＬＥＤ照明装置１０の電源装置１７に含まれた電解コンデンサ１６の寿命が来る前にＬＥＤ照明装置１０の交換を実現させることができる。   According to the lifetime estimation device of the LED lighting device according to the present embodiment configured as described above, the LED lighting device 10 is replaced before the lifetime of the electrolytic capacitor 16 included in the power supply device 17 of the LED lighting device 10 comes. Can be realized.

これにより本実施形態は、ＬＥＤ照明装置１０の交換作業の能率を向上させることができる。また、ＬＥＤ照明装置１０の交換に際してのＬＥＤ照明装置１０の消灯状態を短い時間で解消させることができ、乗りかご１の乗客に対するサービス性を向上させることができる。   Thereby, this embodiment can improve the efficiency of replacement work of the LED lighting device 10. Moreover, the turn-off state of the LED lighting device 10 at the time of replacement of the LED lighting device 10 can be eliminated in a short time, and serviceability for passengers in the car 1 can be improved.

なお、前述した実施形態では、制御装置７に、寿命予測装置１８の寿命判定部１８ｂの判定結果と、通電時間計測部１８ａで積算された通電時間と、温度センサ２０で検知された電解コンデンサ１６の環境温度と共に、カメラ１１の映像と電流センサ２１で検知された電流値とが送信されるようになっているが、本発明は、このように構成することには限られない。カメラ１１を備えずに、制御装置７に、寿命予測装置１８の寿命判定部１８ｂの判定結果と、通電時間計測部１８ａで積算された通電時間と、温度センサ２０で検知された電解コンデンサ１６の環境温度と共に、電流センサ２１で検知された電流値が送信されるようにしてもよく、また、電流センサ２１を備えずに、制御装置７に、寿命予測装置１８の寿命判定部１８ｂの判定結果と、通電時間計測部１８ａで積算された通電時間と、温度センサ２０で検知された電解コンデンサ１６の環境温度と共に、カメラ１１の映像が送信されるようにしてもよい。また、カメラ１１と電流センサ２１とを備えずに、制御装置７に、寿命予測装置１８の寿命判定部１８ｂの判定結果と、通電時間計測部１８ａで積算された通電時間と、温度センサ２０で検知された電解コンデンサ１６の環境温度が送信されるようにしてもよい。   In the embodiment described above, the control device 7 has the determination result of the life determination unit 18 b of the life prediction device 18, the energization time accumulated by the energization time measurement unit 18 a, and the electrolytic capacitor 16 detected by the temperature sensor 20. The image of the camera 11 and the current value detected by the current sensor 21 are transmitted together with the ambient temperature, but the present invention is not limited to this configuration. Without the camera 11, the control device 7 has the determination result of the life determination unit 18 b of the life prediction device 18, the energization time accumulated by the energization time measurement unit 18 a, and the electrolytic capacitor 16 detected by the temperature sensor 20. The current value detected by the current sensor 21 may be transmitted together with the environmental temperature, and the determination result of the life determination unit 18b of the life prediction device 18 is not provided in the current sensor 21 and is sent to the control device 7. The image of the camera 11 may be transmitted together with the energization time accumulated by the energization time measurement unit 18a and the environmental temperature of the electrolytic capacitor 16 detected by the temperature sensor 20. In addition, the camera 11 and the current sensor 21 are not provided, and the control device 7 is connected to the determination result of the life determination unit 18b of the life prediction device 18, the energization time accumulated by the energization time measurement unit 18a, and the temperature sensor 20. The detected environmental temperature of the electrolytic capacitor 16 may be transmitted.

さらに寿命予測装置１８から制御装置７に、通電時間計測部１８ａで積算された通電時間と、温度センサ２０で検知された電解コンデンサ１６の環境温度を送信させずに、寿命判定部１８ｂの判定結果のみを送信させるようにしてもよい。   Furthermore, the determination result of the lifetime determination unit 18b is transmitted without transmitting the energization time accumulated by the energization time measurement unit 18a and the environmental temperature of the electrolytic capacitor 16 detected by the temperature sensor 20 from the lifetime prediction device 18 to the control device 7. May be transmitted.

また、前述した実施形態では、図６のフローチャートの手順Ｓ２の判定で、積算された通電時間が交換時間閾値に至ってないと判定されたときに、手順Ｓ１に戻るように構成されているが、このように手順Ｓ１に戻らずに、積算された通電時間が交換時間閾値に至ってないと判定されたときには、寿命判定部１８ｂの判定結果と、その段階における積算された通電時間と、温度センサ２０で検知された電解コンデンサ１６の環境温度とを制御装置７に送信させ、これらの寿命判定部１８ｂの判定結果、その段階における積算された通電時間、及び温度センサ２０で検知された電解コンデンサ１６の環境温度を、監視装置３０、通信回線３１を介して管制センター３２に送信させるようにしてもよい。   Further, in the above-described embodiment, when it is determined in step S2 in the flowchart of FIG. 6 that the accumulated energization time has not reached the replacement time threshold, the process returns to step S1. In this way, when it is determined that the accumulated energization time has not reached the replacement time threshold without returning to step S1, the determination result of the life determination unit 18b, the accumulated energization time at that stage, and the temperature sensor 20 The environmental temperature of the electrolytic capacitor 16 detected in step S1 is transmitted to the control device 7, the determination result of the life determination unit 18b, the accumulated energization time at that stage, and the electrolytic capacitor 16 detected by the temperature sensor 20 The environmental temperature may be transmitted to the control center 32 via the monitoring device 30 and the communication line 31.

このように構成したものでは、管制センター３２において、あるいは管制センター３２からの情報を受信する保守端末３３において、積算された通電時間に応じてＬＥＤ照明装置１０の交換時期の予測管理を実現させることができる。   With this configuration, the control center 32 or the maintenance terminal 33 that receives information from the control center 32 realizes predictive management of the replacement timing of the LED lighting device 10 according to the accumulated energization time. Can do.

また、前述した実施形態では、寿命予測装置１８が送信部１８ｄを備え、寿命予測装置１８の寿命判定部１８ｂの判定結果、通電時間計測部１８ａで積算された通電時間、及び温度センサ２０で検知された電解コンデンサ１６の環境温度を、送信部１８ｄを介して制御装置７に送信させる構成になっているが、寿命予測装置１８が送信部１８ｄを備えない構成にしてもよい。このように送信部１８ｄを備えない構成であっても、積算された通電時間が交換時間閾値に至ったときには、乗りかご１内のＬＥＤ照明装置１０の照明がちらついた点灯状態となるので、乗りかご１内の乗客は、ＬＥＤ照明装置１０に何らかの異常が生じていることを目視により確認することができる。したがって、乗客からエレベーター装置の管理者等への連絡により、電解コンデンサ１６の寿命が来る前にＬＥＤ照明装置１０の交換を実現させることができる。   In the above-described embodiment, the life prediction device 18 includes the transmission unit 18d, and the determination result of the life determination unit 18b of the life prediction device 18, the energization time accumulated by the energization time measurement unit 18a, and the temperature sensor 20 detect The environmental temperature of the electrolytic capacitor 16 is transmitted to the control device 7 via the transmission unit 18d. However, the lifetime prediction device 18 may not include the transmission unit 18d. Even when the transmission unit 18d is not provided as described above, when the accumulated energization time reaches the replacement time threshold value, the lighting of the LED lighting device 10 in the car 1 is in a flickering lighting state. A passenger in the car 1 can visually confirm that some abnormality has occurred in the LED lighting device 10. Therefore, the exchange of the LED lighting device 10 can be realized before the lifetime of the electrolytic capacitor 16 comes by contact from the passenger to the manager of the elevator device.

また、前述した実施形態では、寿命判定部１８ｂにおける積算された通電時間が交換時間閾値に至ったとの判定に応じて、供給電流制御部１８ｃは電流値が大きい値と小さい値の連続的な繰り返しとなるようにＬＥＤ１５に供給される電流を制御し、ＬＥＤ照明装置１０の照明をちらつかせる点灯状態にするものから成っているが、本発明は、このように構成することには限られない。   In the above-described embodiment, the supply current control unit 18c continuously repeats a large current value and a small value in response to the determination that the accumulated energization time in the life determination unit 18b has reached the replacement time threshold. Although it consists of what controls the electric current supplied to LED15 so that it may become, and makes it the lighting state which flickers the illumination of LED lighting apparatus 10, this invention is not restricted to such a structure.

ＬＥＤ１５を発光色が変化するものによって構成し、供給電流制御部１８ｃを、寿命判定部１８ｂにおける積算された通電時間が交換時間閾値に至ったとの判定に応じて、ＬＥＤ１５に供給される電流を、ＬＥＤ１５の発光色をそれまでとは変化させる電流に制御する構成にしてもよい。また、供給電流制御部１８ｃの制御により、交換時間閾値に至る少し前から、ＬＥＤ１５の発光色を例えばそれまでは白色光だったものを、交換時間閾値に近づくに従って黄色光、赤色光等のように発光色を複数段階で変化させるように構成してもよい。   The LED 15 is configured with a light emitting color change, and the supply current control unit 18c determines the current supplied to the LED 15 in accordance with the determination that the accumulated energization time in the life determination unit 18b has reached the replacement time threshold. You may make it the structure which controls to the electric current which changes the luminescent color of LED15 from before. Further, under the control of the supply current control unit 18c, the light emission color of the LED 15 is, for example, white light until then until the replacement time threshold is reached, such as yellow light, red light, etc. as it approaches the replacement time threshold. Alternatively, the emission color may be changed in a plurality of stages.

また、前述した実施形態にあっても、供給電流制御部１８ｃの制御により、交換時間閾値に至る少し前から、ＬＥＤ照明装置１０を比較的長い周期で電流値を変化させて、ＬＥＤ照明装置１０の照明をちらつかせている状態から、次第に電流値の変化の周期が短くなるように、電流値の変化の周期を複数段階で変化させるようにしてもよい。その他、人間がちらつきを認識しにくいが、カメラで撮影可能な程度に短い周期（例えば周波数３０Ｈｚ以上）に設定して、乗客には極力ちらつきを意識させずに、カメラ映像でちらつきを検知してもよい。   Further, even in the above-described embodiment, the LED lighting device 10 is changed by changing the current value of the LED lighting device 10 with a comparatively long cycle slightly before reaching the replacement time threshold under the control of the supply current control unit 18c. The current value change period may be changed in a plurality of stages so that the current value change period gradually becomes shorter from the state in which the illumination is flickering. In addition, although it is difficult for humans to recognize flicker, set the cycle so short that it can be taken with a camera (for example, frequency 30 Hz or more) and detect flicker in the camera image without making the passenger aware of flicker as much as possible. Also good.
