Description

本発明は、通常は外部の商用電源からの電力でＬＥＤを点灯させ、停電時には内部のバックアップ電源の電力でＬＥＤの点灯を継続させるＬＥＤ照明装置に関する。 The present invention relates to an LED lighting device that normally lights an LED with electric power from an external commercial power source and continues to light the LED with electric power of an internal backup power source in the event of a power failure.

この種の停電時にＬＥＤの点灯を継続することのできるＬＥＤ照明装置では、外部の商用電源からの電力供給が停止している状態でＬＥＤを点灯させなければならないので、内部にバックアップ電源を備えており、そのバックアップ電源からの電力でＬＥＤを点灯させるように構成されている（例えば、特許文献１参照）。 In an LED lighting device that can continue to turn on the LED during this type of power failure, the LED must be turned on while the power supply from the external commercial power supply is stopped, so an internal backup power supply is provided. The LED is lit by the electric power from the backup power source (see, for example, Patent Document 1).

一方、ＬＥＤの輝度は印加される電圧ではなく流れる電流値によって変化するので、ＬＥＤに流れる電流値を一定値に保持するためのＤＣＤＣコンバータを駆動ＩＣとして用いている。なお、この駆動ＩＣは各種存在するが、例えば、ＬＩＮＥＡＲ ＴＥＣＨＮＯＬＯＧＹ社のＬＴ１６１８と呼ばれるもののように、アジャスト端子を備え、このアジャスト端子に入力される電圧値によって、ＬＥＤに流す電流値を変化させてＬＥＤの輝度を調節することのできるものがある（例えば、非特許文献１参照）。 On the other hand, since the brightness of the LED changes not with the applied voltage but with the flowing current value, a DCDC converter for keeping the current value flowing through the LED at a constant value is used as the drive IC. There are various types of drive ICs, but for example, like the one called LT1618 of LINEAR TECHNOLOGY, the LED is provided with an adjust terminal, and the current value flowing through the LED is changed according to the voltage value input to the adjust terminal. There are some that can adjust the brightness of the LED (see, for example, Non-Patent Document 1).

特開２０１２−２２６８８６号公報（段落００２０）Japanese Unexamined Patent Publication No. 2012-226886 (paragraph 0020)

ＬＥＤを発光させる駆動ＩＣはＬＥＤに流す電流値を一定値にするため、停電時にバックアップ電源の電力が減少して電圧が低下しても電流値を減少させることなくＬＥＤに供給し続ける。そのため、バックアップ電源の電圧値が限界値を下回ると、急速にＬＥＤへの通電が停止する特性を有している。このため、停電時にＬＥＤの点灯が継続しても、一定の輝度で点灯しているＬＥＤが突然消灯することになり、特に外部からの光が入らない室内では、予告なくＬＥＤが突然消灯すると、それ以降の活動ができなくなるという不具合が生じる。 Since the drive IC that emits light from the LED keeps the current value flowing through the LED constant, it continues to supply the LED without reducing the current value even if the power of the backup power supply decreases and the voltage decreases during a power failure. Therefore, when the voltage value of the backup power supply falls below the limit value, the LED is rapidly de-energized. For this reason, even if the LED continues to light during a power failure, the LED that is lit at a constant brightness will suddenly turn off. Especially in a room where external light does not enter, if the LED suddenly turns off without notice, There is a problem that you cannot do any further activities.

そこで本発明は、上記の問題点に鑑み、定電流制御を行う駆動ＩＣを用いても停電時にＬＥＤが突然消灯することのないＬＥＤ照明装置を提供することを課題とする。 Therefore, in view of the above problems, it is an object of the present invention to provide an LED lighting device in which an LED does not suddenly turn off in the event of a power failure even if a drive IC that performs constant current control is used.

上記課題を解決するために本発明によるＬＥＤ照明装置は、外部の商用電源から供給される交流電力を所定の電圧の直流電力である駆動電力に変換し、複数個のＬＥＤが直列に接続されたＬＥＤ列に一定電流を供給してＬＥＤ列の輝度を一定に保持する定電流制御用の駆動ＩＣに上記駆動電力を供給すると共に、上記商用電源からの電力によってバックアップ電源を充電すると共に、商用電源が停電した際に、バックアップ電源に充電した電力を上記駆動ＩＣに供給して、ＬＥＤ列の点灯を継続するＬＥＤ照明装置において、上記駆動ＩＣは上記のように駆動電力が供給されるものであり、この駆動ＩＣは供給された駆動電力の電圧を昇圧するものであり、かつ、この駆動ＩＣは入力される電圧値によってＬＥＤ列に供給する電流値を変化させるアジャスト端子を有しており、停電が生じていない状態では上記駆動電力の電圧値を分圧してアジャスト端子に入力し、停電が発生した状態では、上記バックアップ電源の電圧を分圧してアジャスト端子に入力させ、このバックアップ電源の電圧の低下に連動して上記ＬＥＤ列に供給する電流値を減少させ、ＬＥＤ列の輝度を低下させることを特徴とする。 In order to solve the above problems, the LED lighting device according to the present invention converts AC power supplied from an external commercial power source into drive power which is DC power of a predetermined voltage, and a plurality of LEDs are connected in series. with supplying a constant current to the LED string to supply the drive power to the drive IC for constant current control to maintain the brightness of the LED string constant, which charges the backup power by the power from the commercial power, a commercial power source In an LED lighting device that supplies the power charged in the backup power supply to the drive IC and continues to light the LED row when the power failure occurs, the drive IC is supplied with the drive power as described above . , This drive IC boosts the voltage of the supplied drive power, and this drive IC has an adjust terminal that changes the current value supplied to the LED train according to the input voltage value, resulting in a power failure. When is not occurring, the voltage value of the drive power is divided and input to the adjust terminal, and when a power failure occurs, the voltage of the backup power supply is divided and input to the adjust terminal, and the voltage of this backup power supply is changed. It is characterized in that the current value supplied to the LED row is reduced in conjunction with the decrease, and the brightness of the LED row is lowered.

バックアップ電源の電圧はＬＥＤ点灯のために電力を消費すると電圧が低下する。そのバックアップ電源の電圧を基準にＬＥＤへの電流値を制御すると、バックアップ電源の電圧の低下に伴ってＬＥＤへの電流値が減少し、ＬＥＤの輝度が連続して暗くなっていくので、ＬＥＤが消灯する前兆を察知することができる。 The voltage of the backup power supply drops when power is consumed to light the LED. When the current value to the LED is controlled based on the voltage of the backup power supply, the current value to the LED decreases as the voltage of the backup power supply decreases, and the brightness of the LED continuously darkens, so that the LED becomes darker. It is possible to detect a sign that the light goes out.

なお、この構成は、上記バックアップ電源はコンデンサで構成されているものに特に有用である。 It should be noted that this configuration is particularly useful when the backup power supply is composed of a capacitor.

以上の説明から明らかなように、本発明は、停電時のバックアップ電源の電力でＬＥＤの点灯を継続する場合に、ＬＥＤの輝度を徐々に減少させるので、バックアップ電源の電力が消失してＬＥＤが消灯するタイミングを容易に推測することができる。また、一定の輝度で点灯させ続ける場合に対してＬＥＤに流す電流値を徐々に減少させるので、停電発生時からＬＥＤが消灯するまでの時間を長くすることができる。 As is clear from the above description, in the present invention, when the LED is continuously lit by the power of the backup power supply at the time of power failure, the brightness of the LED is gradually reduced, so that the power of the backup power supply is lost and the LED is turned on. The timing of turning off the lights can be easily estimated. Further, since the current value flowing through the LED is gradually reduced when the LED is continuously lit with a constant brightness, the time from the occurrence of a power failure until the LED is turned off can be lengthened.

図１を参照して、１は外部の商用電源であり、１００ボルトの交流電力を供給するものである。この商用電源１から点消灯用の壁スイッチ１１を介して交流電力がスイッチ検知回路２に入力される。壁スイッチ１１がオン状態にあると商用電源１からの交流電力がスイッチ検知回路２に入力されるので、スイッチ検知回路２は壁スイッチ１１がオンになったことを検知することができ、逆にスイッチ検知回路２に交流電力の供給が停止すると壁スイッチ１１がオフになったと判断する。 With reference to FIG. 1, reference numeral 1 denotes an external commercial power source, which supplies 100 volts of AC power. AC power is input to the switch detection circuit 2 from the commercial power supply 1 via the wall switch 11 for turning on and off. When the wall switch 11 is in the ON state, the AC power from the commercial power supply 1 is input to the switch detection circuit 2, so that the switch detection circuit 2 can detect that the wall switch 11 is turned on, and conversely. When the supply of AC power to the switch detection circuit 2 is stopped, it is determined that the wall switch 11 is turned off.

３は電源部であり、上記壁スイッチ１１のオンオフ状態の如何に関わらず、上記商用電源１からの交流電源が供給されるように配線されている。この電源部３は商用電源１からの１００ボルトの交流電力を整流して１次電圧（ＶＡ）の直流電力に変換する。この１次電圧ＶＡは例えば１２ボルトである。また、この電源部３は電解二重層コンデンサからなるバックアップ電源３１を充電する。なお、バックアップ電源３１に充電されている電圧をＶＥとする。 Reference numeral 3 denotes a power supply unit, which is wired so that the AC power supply from the commercial power supply 1 is supplied regardless of the on / off state of the wall switch 11. The power supply unit 3 rectifies 100 volt AC power from the commercial power supply 1 and converts it into DC power of the primary voltage (VA). This primary voltage VA is, for example, 12 volts. Further, the power supply unit 3 charges a backup power supply 31 composed of an electric double layer capacitor. The voltage charged in the backup power supply 31 is defined as VE.

上記１次電圧ＶＡの直流電力は定電流制御部４に入力される。この定電流制御部４は入力された１２ボルト程度の直流電力を昇圧して、ＬＥＤ５を所定の照度で点灯させるための一定電流をＬＥＤ５に供給する。なお、商用電源１が作動し交流電力の供給が継続している状態では、壁スイッチ１１がオンオフすることによってＬＥＤ５は点消灯する。 The DC power of the primary voltage VA is input to the constant current control unit 4. The constant current control unit 4 boosts the input DC power of about 12 volts and supplies the LED 5 with a constant current for lighting the LED 5 with a predetermined illuminance. In a state where the commercial power source 1 is operating and the supply of AC power is continued, the LED 5 is turned on and off by turning the wall switch 11 on and off.

商用電源１からの交流電力の供給が停止する、すなわち停電が発生すると、壁スイッチ１１のオンオフ状態の如何に関わらず、バックアップ電源３１に充電されている電力でＬＥＤ５を点灯させる。停電の発生は停電検知部６で検知する。この停電検知部６は停電が発生するとバックアップ電源３１に充電されている電力を定電流制御部４に供給する。 When the supply of AC power from the commercial power supply 1 is stopped, that is, when a power failure occurs, the LED 5 is turned on with the power charged in the backup power supply 31 regardless of whether the wall switch 11 is on or off. The occurrence of a power failure is detected by the power failure detection unit 6. When a power failure occurs, the power failure detection unit 6 supplies the power charged in the backup power supply 31 to the constant current control unit 4.

次に、定電流制御部４の構成を図２に示す。図において中央に記載したのはＤＣＤＣコンバータである駆動ＩＣ７である。この駆動ＩＣ７はアジャスト端子（ＩＡＤＪ）７１をグランド（ＧＮＤ）に接続するとＩＳＰ−ＩＳＮピン間の電圧が一定値（５０ｍｖ程度）に制御されるため、ＬＥＤに供給される電流値が一定値に制御される。 Next, the configuration of the constant current control unit 4 is shown in FIG. The drive IC 7 which is a DCDC converter is described in the center of the figure. When the adjustment terminal (IADJ) 71 is connected to the ground (GND) of this drive IC 7, the voltage between the ISP and ISN pins is controlled to a constant value (about 50 mv), so that the current value supplied to the LED is controlled to a constant value. Will be done.

図に示すようにアジャスト端子（ＩＡＤＪ）に分圧抵抗４２，４３，４４で生成されるｂ点の分圧電圧を入力すると、その分圧電電圧に応じてＩＳＰ−ＩＳＮピン間の電圧が変化するように構成されているので、結果的にＬＥＤ５に流れる電流値が変化し、ＬＥＤの輝度が変化する。 As shown in the figure, when the voltage dividing voltage at point b generated by the voltage dividing resistors 42, 43, 44 is input to the adjust terminal (IADJ), the voltage between the ISP and ISN pins changes according to the piezoelectric voltage. As a result, the value of the current flowing through the LED 5 changes, and the brightness of the LED changes.

例えば、アジャスト端子（ＩＡＤＪ）に１．５ボルトの電圧を入力するとＩＳＰ−ＩＳＮピン間の電圧が５０ｍｖになる場合、１次電圧（ＶＡ）（１２ボルト）を分圧してｂ点の分圧電圧が１．５ボルトになるように設定する。すると、１次電圧（ＶＡ）が発生している状態ではＬＥＤ５は一定の輝度で点灯する。 For example, if the voltage between the ISP and ISN pins becomes 50 mv when a voltage of 1.5 volts is input to the adjust terminal (IADJ), the primary voltage (VA) (12 volts) is divided to divide the voltage at point b. Is set to 1.5 volts. Then, in the state where the primary voltage (VA) is generated, the LED 5 lights up with a constant brightness.

バックアップ電源３１の電圧（ＶＥ）を８ボルトとすると、逆流防止用のダイオード４１の順方向降下電圧ＶＦを０．６ボルトとして、ａ点の分圧電圧が７．４ボルトより高くなるように設定し、通常時にバックアップ電源３１から電力が流れないようにしておく。 Assuming that the voltage (VE) of the backup power supply 31 is 8 volts, the forward voltage drop VF of the diode 41 for preventing backflow is set to 0.6 volts, and the voltage dividing voltage at point a is set to be higher than 7.4 volts. However, the power does not flow from the backup power supply 31 at normal times.

停電が発生すると１次電圧（ＶＡ）が消失するので、ｂ点の分圧電圧は７．４ボルトを分圧抵抗４３，４４で分圧した値となる。但し、ＬＥＤ５はバックアップ電源３１の電力で点灯を継続するので、ＶＥは徐々に低下し、その低下に伴ってｂ点の分圧電圧も低下する。その結果、ＬＥＤ５に流れる電流値が減少して、ＬＥＤ５は徐々に暗くなる。このように、停電発生時にはＬＥＤ５が徐々に暗くなるので、消灯するまでの時間を予測することが容易になり、かつ停電後に一定の輝度で点灯を継続させる場合より点灯時間を長くすることができる。 When a power failure occurs, the primary voltage (VA) disappears, so the voltage divider at point b is the value obtained by dividing 7.4 volts by the voltage divider resistors 43 and 44. However, since the LED 5 continues to be lit by the power of the backup power supply 31, the VE gradually decreases, and the voltage dividing voltage at point b also decreases as the VE decreases. As a result, the value of the current flowing through the LED 5 decreases, and the LED 5 gradually darkens. In this way, since the LED 5 gradually darkens when a power failure occurs, it is easy to predict the time until the LED 5 is turned off, and the lighting time can be longer than when the lighting is continued at a constant brightness after the power failure. ..
