制御部43は、時間を計時する計時部45の機能、および蓄電池13を点検する点検部46の機能を有している。点検部46では、蓄電池13の充電量を検知するとともに、所定の点検時間にわたって放電させた蓄電池13の電圧や電流等から寿命や異常を判定する。点検部46による点検結果は、制御部43が有する記憶部に記憶し、出力部42から出力できるようにする。 The control unit 43 has a function of a timer unit 45 that measures time and a function of an inspection unit 46 that inspects the storage battery 13 . The inspection unit 46 detects the amount of charge in the storage battery 13, and determines the life and abnormality from the voltage, current, etc. of the storage battery 13 discharged over a predetermined inspection time. The inspection result by the inspection unit 46 is stored in the storage unit of the control unit 43 so that it can be output from the output unit 42 .

そして、制御部43は、明るさセンサ27によって検知される周囲の明るさに応じて点灯回路部40を制御し、光源12を点灯、消灯させる機能を有している。 The control unit 43 has a function of controlling the lighting circuit unit 40 according to the ambient brightness detected by the brightness sensor 27 to turn on/off the light source 12 .

また、制御部43は、明るさセンサ27によって検知される周囲の明るさに応じた光源12の点灯時に、計時部45によって計時される時間に基づいて外部電源Ｅによる光源12の点灯と蓄電池13の電源による光源12の点検点灯とを切り換え、蓄電池13の電源による光源12の点検点灯終了後の蓄電池13を点検部46によって点検する自動点検機能を有している。 Further, when the light source 12 is turned on according to the ambient brightness detected by the brightness sensor 27, the control unit 43 controls the lighting of the light source 12 by the external power source E and the storage battery 13 based on the time measured by the clock unit 45. , and has an automatic inspection function in which the inspection unit 46 inspects the storage battery 13 after the inspection lighting of the light source 12 by the power supply of the storage battery 13 is completed.

さらに、制御部43は、外部電源Ｅが供給されているときに、点検部46により蓄電池13の充電量を検知してもよく、この点検部46によって検知される蓄電池13の充電量が所定値以下の場合、蓄電池13の電源による光源12の点検点灯を実施しない機能を有している。 Further, the control unit 43 may detect the charge amount of the storage battery 13 by the inspection unit 46 when the external power source E is supplied, and the charge amount of the storage battery 13 detected by the inspection unit 46 is a predetermined value. In the following cases, it has a function not to perform inspection lighting of the light source 12 by the power supply of the storage battery 13.

さらに、制御部43は、明るさセンサ27によって検知される周囲の明るさに応じて光源12を点灯させた過去の点灯時間から次回の点灯時間を判断し、この次回の点灯時間から蓄電池13の電源によって光源12を点検点灯させる点検時間を差し引いた時間だけ外部電源Ｅによって光源12を点灯させる機能を有している。 Furthermore, the control unit 43 determines the next lighting time from the past lighting time when the light source 12 was turned on according to the ambient brightness detected by the brightness sensor 27, and determines the next lighting time from the next lighting time. It has a function of lighting the light source 12 by the external power source E for the time after subtracting the inspection time for lighting the light source 12 by the power source.

さらに、制御部43は、明るさセンサ27によって検知される周囲の明るさに応じた光源12の点灯時に、外部電源Ｅによる光源12の点灯から蓄電池13の電源による光源12の点検点灯への切り換えと、蓄電池13の電源による光源12の点検点灯から外部電源Ｅによる光源12の点灯への切り換えと、外部電源Ｅによる光源12の点灯途中での蓄電池13の電源による光源12の点検点灯への切り換えと、のいずれか１つで切り換えを実行する機能を有している。 Furthermore, when the light source 12 is lit according to the ambient brightness detected by the brightness sensor 27, the control unit 43 switches from lighting the light source 12 by the external power source E to inspection lighting of the light source 12 by the power source of the storage battery 13. Then, switching from inspection lighting of the light source 12 by the power of the storage battery 13 to lighting of the light source 12 by the external power source E, and switching to inspection lighting of the light source 12 by the power of the storage battery 13 during lighting of the light source 12 by the external power source E. and has a function of executing switching.

さらに、制御部43は、蓄電池13の電源によって光源12を点検点灯させるときに、蓄電池13からの放電レートを変化させる機能を有している。 Further, the control unit 43 has a function of changing the discharge rate from the storage battery 13 when the light source 12 is turned on for inspection by the power supply of the storage battery 13 .

そして、このように構成された照明装置10は、外部電源Ｅが給電されているときには、外部電源Ｅによって動作する。 The lighting device 10 configured in this manner operates by the external power source E when the external power source E is supplied with power.

夕方となって照明装置10の周囲が暗くなり、明るさセンサ27で検知される明るさの値が所定の点灯判定閾値を下回ると、外部電源Ｅによって点灯回路部40が動作し、光源12を点灯させる。 When the surroundings of the lighting device 10 become dark in the evening and the brightness value detected by the brightness sensor 27 falls below a predetermined lighting determination threshold value, the external power source E operates the lighting circuit unit 40 to turn on the light source 12. light up.

一方、明け方となって照明装置10の周囲が明るくなり、明るさセンサ27で検知される明るさの値が所定の消灯判定閾値を上回ると、点灯回路部40の動作を停止し、光源12を消灯させる。 On the other hand, when the surroundings of the lighting device 10 become bright in the early morning and the brightness value detected by the brightness sensor 27 exceeds a predetermined turn-off determination threshold value, the operation of the lighting circuit unit 40 is stopped and the light source 12 is turned on. turn off the light.

前回の蓄電池13の充電から所定時間経過した場合や、点検部46によって蓄電池13の充電量が所定値以下に減少したことが判定された場合には、蓄電池13を充電する。 When a predetermined time has passed since the previous charging of the storage battery 13, or when the inspection unit 46 determines that the charge amount of the storage battery 13 has decreased below a predetermined value, the storage battery 13 is charged.

また、照明装置10は、外部電源Ｅの停電時には、蓄電池13の電源が放電され、この蓄電池13の電源によって動作する。 In addition, when the external power source E fails, the power source of the storage battery 13 is discharged, and the lighting device 10 is operated by the power source of the storage battery 13 .

この場合にも、夕方となって照明装置10の周囲が暗くなり、明るさセンサ27で検知される明るさの値が所定の点灯判定閾値を下回ると、蓄電池13の電源によって点灯回路部40が動作し、光源12を点灯させる。 Even in this case, when the surroundings of the lighting device 10 become dark in the evening and the brightness value detected by the brightness sensor 27 falls below a predetermined lighting determination threshold, the lighting circuit unit 40 is turned off by the power supply of the storage battery 13. It operates and causes the light source 12 to light up.

一方、明け方となって照明装置10の周囲が明るくなり、明るさセンサ27で検知される明るさの値が所定の消灯判定閾値を上回ると、点灯回路部40の動作を停止し、光源12を消灯させる。 On the other hand, when the surroundings of the lighting device 10 become bright in the early morning and the brightness value detected by the brightness sensor 27 exceeds a predetermined turn-off determination threshold value, the operation of the lighting circuit unit 40 is stopped and the light source 12 is turned on. turn off the light.

そして、照明装置10は、停電が解消されて外部電源Ｅの給電が再開されれば、上述のように外部電源Ｅによって動作し、蓄電池13を充電する。 Then, when the power failure is resolved and the power supply from the external power source E is resumed, the lighting device 10 operates with the external power source E and charges the storage battery 13 as described above.

また、照明装置10は、制御部43の自動点検機能により、蓄電池13の点検を自動的に行う。自動点検機能では、明るさセンサ27によって検知される周囲の明るさに応じて光源12を点灯させる点灯期間中に、計時部45によって計時される時間に基づいて外部電源Ｅによる光源12の点灯と蓄電池13の電源による光源12の点検点灯とを切り換え、蓄電池13の電源による光源12の点検点灯終了後の蓄電池13を点検部46によって点検する。つまり、光源12を点灯させる点灯期間において、これまで外部電源Ｅで光源12を点灯させた時間を、蓄電池13の点検に充てることになる。 Also, the lighting device 10 automatically inspects the storage battery 13 by the automatic inspection function of the control unit 43 . In the automatic inspection function, during the lighting period in which the light source 12 is lit according to the ambient brightness detected by the brightness sensor 27, the lighting of the light source 12 by the external power source E is performed based on the time measured by the timer 45. After the inspection lighting of the light source 12 by the power supply of the storage battery 13 is switched, the storage battery 13 is inspected by the inspection unit 46 after the inspection lighting of the light source 12 by the power supply of the storage battery 13 is completed. In other words, during the lighting period during which the light source 12 is turned on, the time during which the light source 12 has been turned on by the external power supply E is used for checking the storage battery 13 .

例えば、図３(a)に示すように、明るさセンサ27によって検知される周囲の明るさに応じて光源12を点灯させる点灯期間が始まると、まず、外部電源Ｅによって光源12を通常点灯させる。外部電源Ｅによる光源12の点灯から所定時間後に、蓄電池13の電源による光源12の点検点灯に切り換える。蓄電池13の電源による光源12の点検点灯が所定時間以上継続され、点灯期間が終わると、光源12を消灯させる。蓄電池13の電源による光源12の点検点灯終了後の蓄電池13を点検部46によって点検し、蓄電池13の充電量、寿命や異常を判定する。 For example, as shown in FIG. 3(a), when the lighting period for lighting the light source 12 according to the ambient brightness detected by the brightness sensor 27 starts, first, the light source 12 is normally lit by the external power source E. . After a predetermined time has passed since the lighting of the light source 12 by the external power source E, the lighting of the light source 12 is switched to the inspection lighting of the light source 12 by the power source of the storage battery 13 . The inspection lighting of the light source 12 by the power supply of the storage battery 13 continues for a predetermined time or more, and when the lighting period ends, the light source 12 is turned off. The inspection unit 46 inspects the storage battery 13 after completion of inspection lighting of the light source 12 by the power source of the storage battery 13, and determines the charge amount, lifespan, and abnormality of the storage battery 13. FIG.

この場合、制御部43は、明るさセンサ27によって検知される周囲の明るさに応じて光源12を点灯させた過去の点灯時間（点灯期間）から次回の点灯時間（点灯期間）を判断し、この次回の点灯時間から蓄電池13の電源によって光源12を点検点灯させる点検時間を差し引いた時間だけ外部電源Ｅによって光源12を点灯させる。これにより、蓄電池13の電源によって光源12を点検点灯させる点検時間が短かったり長かったりすることなく、適切な時間に設定される。 In this case, the control unit 43 determines the next lighting time (lighting period) from the past lighting time (lighting period) when the light source 12 was lit according to the ambient brightness detected by the brightness sensor 27, The light source 12 is lit by the external power source E for the time obtained by subtracting the inspection time for checking and lighting the light source 12 by the power supply of the storage battery 13 from the next lighting time. As a result, the inspection time for lighting the light source 12 by the power supply of the storage battery 13 is set to an appropriate time without being short or long.

また、例えば蓄電池13の電源によって光源12を点検点灯させる点検時間を朝方に設定することで、蓄電池13の異常があり、点検中に消灯した場合でも、周囲が徐々に明るくなるため、消灯による影響が少ない。つまり、夜中は外部電源Ｅの電力により明るさが確保できる。 In addition, for example, by setting the inspection time to light the light source 12 by the power supply of the storage battery 13 in the early morning, even if there is an abnormality in the storage battery 13 and the light is turned off during inspection, the surroundings will gradually become brighter, so the influence of the light will be reduced. Less is. In other words, brightness can be ensured by the electric power of the external power source E during the night.

また、図３(b)に示すように、明るさセンサ27によって検知される周囲の明るさに応じて光源12を点灯させる点灯期間が始まると、まず、蓄電池13の電源によって光源12を所定の点検時間だけ点検点灯させる。蓄電池13の電源による光源12の点検点灯の点検時間が経過したら、外部電源Ｅによる光源12の通常点灯に切り換える。点灯期間が終わると、光源12を消灯させる。蓄電池13の電源による光源12の点検点灯終了後の蓄電池13を点検部46によって点検し、蓄電池13の充電量、寿命や異常等を判定する。 Further, as shown in FIG. 3(b), when the lighting period for lighting the light source 12 according to the ambient brightness detected by the brightness sensor 27 starts, first, the light source 12 is turned on by the power supply of the storage battery 13 at a predetermined level. The inspection light is turned on only during the inspection time. When the inspection time of the inspection lighting of the light source 12 by the power supply of the storage battery 13 has passed, the light source 12 is switched to the normal lighting by the external power supply E. After the lighting period ends, the light source 12 is turned off. The inspection unit 46 inspects the storage battery 13 after completion of inspection and lighting of the light source 12 by the power source of the storage battery 13, and determines the amount of charge, life, abnormality, etc. of the storage battery 13. FIG.

この場合、明るさセンサ27によって検知される周囲の明るさに応じて光源12を点灯させる点灯期間の変化にかかわらず、蓄電池13の電源によって光源12を点検点灯させる点検時間を一定にでき、蓄電池13の点検の判定精度を高めることができる。また、まず蓄電池13の電源により点検点灯を行うため、蓄電池13の異常を早目に検知することができる。 In this case, regardless of changes in the lighting period for lighting the light source 12 according to the ambient brightness detected by the brightness sensor 27, the inspection time for lighting the light source 12 for inspection can be fixed by the power supply of the storage battery 13. It is possible to improve the judgment accuracy of the 13 inspections. In addition, since inspection lighting is first performed using the power supply of the storage battery 13, an abnormality of the storage battery 13 can be detected early.

また、図３(c)に示すように、明るさセンサ27によって検知される周囲の明るさに応じて光源12を点灯させる点灯期間が始まると、まず、外部電源Ｅによって光源12を通常点灯させる。外部電源Ｅによる光源12の点灯から所定時間後に、蓄電池13の電源による光源12の点検点灯に切り換える。次に、蓄電池13の電源による光源12の点検点灯から所定の点検時間が経過したら、外部電源Ｅによる光源12の通常点灯に切り換える。点灯期間が終わると、光源12を消灯させる。蓄電池13の電源による光源12の点検点灯終了後の蓄電池13を点検部46によって点検し、蓄電池13の充電量、寿命や異常等を判定する。 Further, as shown in FIG. 3(c), when the lighting period in which the light source 12 is lit according to the ambient brightness detected by the brightness sensor 27 begins, first, the light source 12 is normally lit by the external power supply E. . After a predetermined time has passed since the lighting of the light source 12 by the external power source E, the lighting of the light source 12 is switched to the inspection lighting of the light source 12 by the power source of the storage battery 13 . Next, after a predetermined inspection time has passed since the inspection lighting of the light source 12 by the power source of the storage battery 13, the light source 12 is switched to normal lighting by the external power source E. After the lighting period ends, the light source 12 is turned off. The inspection unit 46 inspects the storage battery 13 after completion of inspection and lighting of the light source 12 by the power source of the storage battery 13, and determines the amount of charge, life, abnormality, etc. of the storage battery 13. FIG.

この場合にも、明るさセンサ27によって検知される周囲の明るさに応じて光源12を点灯させる点灯期間の変化にかかわらず、蓄電池13の電源によって光源12を点検点灯させる点検時間を一定にでき、蓄電池13の点検の判定精度を高めることができる。 In this case as well, regardless of changes in the lighting period for lighting the light source 12 according to the ambient brightness detected by the brightness sensor 27, the inspection time for lighting the light source 12 for inspection by the power supply from the storage battery 13 can be kept constant. , the determination accuracy of the inspection of the storage battery 13 can be improved.

また、蓄電池13の電源によって光源12を点検点灯させるときには、蓄電池13からの放電レートを変化させてもよい。例えば、蓄電池13の容量が大きいと、長い点検時間を必要とし、明るさセンサ27の検知に基づく１回の点灯期間では自動点検が完了しない場合もあるが、蓄電池13からの放電レートを高くすることにより、つまり光源12の明るさを通常に点灯したときの明るさよりも明るくすることにより、明るさセンサ27の検知に基づく１回の点灯期間中に蓄電池13の自動点検が完了するようにする。 Further, when the light source 12 is lit for inspection by the power supply of the storage battery 13, the discharge rate from the storage battery 13 may be changed. For example, if the storage battery 13 has a large capacity, a long inspection time is required, and the automatic inspection may not be completed in one lighting period based on the detection of the brightness sensor 27, but the discharge rate from the storage battery 13 is increased. In other words, by making the brightness of the light source 12 brighter than when it is lit normally, the automatic inspection of the storage battery 13 is completed during one lighting period based on the detection of the brightness sensor 27. .

このような蓄電池13の自動点検は、明るさセンサ27によって検知される周囲の明るさに応じた光源12の点灯時に毎回行ってもよいし、光源12の累積点灯時間等に応じて一定期間毎に行ってもよい。例えば、光源12の累積点灯時間が５０時間等の所定時間経過したら、自動点検を行うようにしてもよい。 Such automatic inspection of the storage battery 13 may be performed each time the light source 12 is turned on according to the ambient brightness detected by the brightness sensor 27, or at regular intervals according to the cumulative lighting time of the light source 12. You can go to For example, automatic inspection may be performed after the cumulative lighting time of the light source 12 has passed a predetermined time such as 50 hours.

蓄電池13の点検は、蓄電池13の寿命や異常を推測可能とする短時間の点検時間とする場合と、蓄電池13の実際の充電容量を確認する長時間の点検時間とする場合とがある。この場合、短時間の点検時間での点検を例えば３回等の所定回数行う毎に、長時間の点検時間での点検を行うようにしてもよい。 The storage battery 13 may be inspected for a short period of time such that the service life or abnormality of the storage battery 13 can be estimated, or for a long period of time for confirming the actual charge capacity of the storage battery 13 . In this case, the inspection may be performed with a long inspection time every time the inspection with the short inspection time is performed a predetermined number of times, for example, three times.

なお、点検の終えた蓄電池13は充電するが、点検サイクルは蓄電池13の充電可能時間よりも長い関係にある。つまり、次回の点検までに蓄電池13の充電が完了する関係にある。 Although the storage battery 13 that has been inspected is charged, the inspection cycle is longer than the chargeable time of the storage battery 13 . In other words, the charging of the storage battery 13 is completed before the next inspection.

また、外部電源Ｅが給電されているとともに点検部46によって検知される蓄電池13の充電量が所定値以下の場合、停電が生じると蓄電池13の充電不足が生じる可能性があるため、蓄電池13の電源による光源12の点検点灯を実施しない。 In addition, when the external power supply E is supplied and the amount of charge of the storage battery 13 detected by the inspection unit 46 is less than a predetermined value, there is a possibility that the storage battery 13 will be insufficiently charged when a power failure occurs. Do not perform inspection lighting of the light source 12 by the power supply.

そして、蓄電池13の点検結果は、出力部42によってサーバーに送信したり、記憶部に記憶して後で出力可能とする。 The inspection result of the storage battery 13 can be transmitted to the server by the output unit 42 or stored in the storage unit and output later.

なお、蓄電池13の電源によって光源12を点検点灯させているときに、蓄電池13の電圧低下などの異常が生じた場合には、外部電源Ｅによる光源12の通常点灯に切り換え、点灯期間中の光源12の点灯状態を維持するようにしてもよい。 If an abnormality such as a voltage drop in the storage battery 13 occurs while the light source 12 is lit for inspection by the power supply of the storage battery 13, the light source 12 is switched to normal lighting by the external power supply E, and the light source during the lighting period is switched to normal lighting. 12 lighting states may be maintained.

そして、このように構成された照明装置10によれば、光源12の点灯時に計時部45によって計時される時間に基づいて外部電源Ｅによる光源12の点灯と蓄電池13の電源による光源12の点検点灯とを切り換え、蓄電池13の電源による光源12の点検点灯終了後の蓄電池13を点検部46によって点検することにより、これまで外部電源Ｅで光源12を点灯させた時間を蓄電池13の点検に充てることができ、蓄電池13の点検を自動的に行え、点検の手間を低減することができる。 According to the illumination device 10 configured as described above, the lighting of the light source 12 by the external power supply E and the inspection lighting of the light source 12 by the power of the storage battery 13 are performed based on the time measured by the timer 45 when the light source 12 is turned on. , and the storage battery 13 is inspected by the inspection unit 46 after inspection and lighting of the light source 12 by the power source of the storage battery 13 is completed, so that the time during which the light source 12 has been lit by the external power source E can be used for inspection of the storage battery 13. The inspection of the storage battery 13 can be automatically performed, and the trouble of inspection can be reduced.

また、外部電源Ｅが給電されているとともに点検部46によって検知される蓄電池13の充電量が所定値以下の場合、蓄電池13の電源による光源12の点検点灯を実施しないことにより、停電時に備えて蓄電池13の充電不足が生じるのを防止できる。 In addition, when the external power supply E is being supplied and the charge amount of the storage battery 13 detected by the inspection unit 46 is less than a predetermined value, the inspection lighting of the light source 12 by the power supply of the storage battery 13 is not performed. Insufficient charging of the storage battery 13 can be prevented.

また、明るさセンサ27によって検知される周囲の明るさに応じて光源12を点灯させた過去の点灯時間（点灯期間）から次回の点灯時間（点灯期間）を判断し、この次回の点灯時間から蓄電池13の電源によって光源12を点検点灯させる点検時間を差し引いた時間だけ外部電源Ｅによって光源12を点灯させることにより、蓄電池13の電源によって光源12を点検点灯させる点検時間が短かったり長かったりすることなく、適切な時間に設定できる。 Also, the next lighting time (lighting period) is determined from the past lighting time (lighting period) when the light source 12 was lit according to the ambient brightness detected by the brightness sensor 27, and the next lighting time (lighting period) is determined from this next lighting time. By lighting the light source 12 by the external power supply E for the time after subtracting the inspection time for checking and lighting the light source 12 by the power of the storage battery 13, the inspection time for checking and lighting the light source 12 by the power of the storage battery 13 can be shortened or long. can be set to an appropriate time.

また、蓄電池13の電源によって光源12を点検点灯させるときには、蓄電池13からの放電レートを例えば高く変化させることにより、蓄電池13の容量が大きくても、明るさセンサ27の検知に基づく１回の点灯期間中に蓄電池13の自動点検を完了させることができる。 In addition, when the light source 12 is lit for inspection by the power supply of the storage battery 13, by changing the discharge rate from the storage battery 13 to a high value, for example, even if the capacity of the storage battery 13 is large, one lighting based on the detection of the brightness sensor 27 is performed. Automatic inspection of the storage battery 13 can be completed during the period.

なお、照明装置は、防犯灯や街路灯以外に、屋外に設置されて周囲の明るさに応じて光源を点灯、消灯する例えばガーデン灯等の他の照明装置にも適用できる。 In addition to crime prevention lights and street lights, the lighting apparatus can also be applied to other lighting apparatuses, such as garden lights, which are installed outdoors and turn on and off the light source according to the brightness of the surroundings.
