従来、帯板状のプリント基板に多数の発光ダイオード（ＬＥＤ）を配列し、管状のバルブ内に配設して、従来の蛍光灯と同様な形状にした装飾ランプがある（特許文献１）。 Conventionally, there is a decorative lamp in which a large number of light emitting diodes (LEDs) are arranged on a strip-like printed circuit board and arranged in a tubular bulb, which has the same shape as a conventional fluorescent lamp (Patent Document 1).

しかし、このような従来の装飾ランプでは、通常の照明用に用い、さらに停電時など非常用に対応できる機能を有しておらず、緊急事態に十分に対処できるＬＥＤ照明装置ではなかった。 However, such a conventional decorative lamp is not an LED lighting device that can be used for normal lighting and does not have an emergency function such as a power failure, and can sufficiently cope with an emergency situation.

また、従来のＬＥＤ照明装置自体を蛍光灯照明器具から取り外ずしても点灯させることができなかった（特許文献２）。
さらに、誘導音をＬＥＤ照明装置から発するようなものではなかった。

次に実施例１の作用について説明する。
定常時には交流電源から供給された電源により、ＬＥＤは点灯している。しかし、コンセントのスイッチはＯＮのままで、停電のため交流電源の供給が無くなるので、停電検知手段が動作し、停電と判断し、ＬＥＤを点灯させることができる。Next, the operation of the first embodiment will be described.
In steady state, the LED is lit by the power supplied from the AC power source. However, since the AC switch is not supplied due to a power failure while the outlet switch remains on, the power failure detection means operates to determine that a power failure has occurred and to light the LED.

この実施例１によれば、従来の蛍光灯に置き換えて使用することができ、すでに設置されている非常用蛍光灯器具の設備を使用して非常用のＬＥＤ照明装置を実現することができる。
しかし、本発明の実施例では、人の手の届くような位置たとえば壁際や廊下隅、非常口などに配置することが好ましい。停電時にはこのＬＥＤ照明装置は管体に内臓する直流電源により点灯する。According to the first embodiment, it can be used in place of a conventional fluorescent lamp, and an emergency LED lighting device can be realized by using the equipment of an already installed emergency fluorescent lamp apparatus.
However, in the embodiment of the present invention, it is preferable to arrange at a position that can be reached by a person such as a wall, a corridor corner, or an emergency exit. In the event of a power failure, the LED lighting device is lit by a DC power supply built in the tube.

図５は実施例１の動作を説明するための回路図である。図５を用いて実施例１の回路動作を説明する。図５において、２０は外部から供給される交流電源、２１は通常の点灯用のＯＮ、ＯＦＦスイッチ、２２はＬＥＤ照明装置の口金１の端子、２３は全波整流回路、２４は複数のＬＥＤ、２５はＬＥＤ照明装置を照明器具から取り外した時をＯＮとなるスイッチ、２６はワンチップマイコンを含む制御回路、２７は逆流防止のダイオード、２８は管体に内臓の直流電源、２９は停電検知手段、３０は停電検知手段２９でＯＦＦとなるスイッチである。 FIG. 5 is a circuit diagram for explaining the operation of the first embodiment. The circuit operation of the first embodiment will be described with reference to FIG. In FIG. 5, 20 is an AC power source supplied from the outside, 21 is an ON / OFF switch for normal lighting, 22 is a terminal of the base 1 of the LED lighting device, 23 is a full-wave rectifier circuit, 24 is a plurality of LEDs, 25 is a switch that is turned on when the LED lighting device is removed from the lighting fixture, 26 is a control circuit including a one-chip microcomputer, 27 is a diode for preventing backflow, 28 is a DC power supply built in the tube, 29 is a power failure detection means , 30 are switches that are turned off by the power failure detection means 29.

この実施例１の回路図において、ＬＥＤ照明装置を蛍光灯器具から取り外したとき、スイッチ２５が入り、直流電源２８から供給された電源により複数のＬＥＤ２４が発光する。
避難方向に流れるように発光させるにはあらかじめ制御回路２６とプリント基板の接続パターンを構成することにより方向性を持たせた点滅が可能となる。このような構成にすれば避難用には好ましいことである。In the circuit diagram of the first embodiment, when the LED lighting device is removed from the fluorescent lamp fixture, the switch 25 is turned on, and the plurality of LEDs 24 emit light by the power supplied from the DC power supply 28.
In order to emit light so as to flow in the evacuation direction, the control circuit 26 and the printed circuit board are configured in advance to enable blinking with directivity. Such a configuration is preferable for evacuation.

この実施例１のような構成によれば、停電時暗くなった部屋や廊下でも、非常灯が避難方向を示してくれるので避難口を容易に見つけることができる利点がある。またこれを蛍光灯器具から取り外しても、内臓の直流電源により複数のＬＥＤを点灯させることができる。 According to the configuration of the first embodiment, there is an advantage that an emergency exit can be easily found because an emergency light indicates an evacuation direction even in a room or a corridor that is dark at the time of a power failure. Moreover, even if this is removed from the fluorescent lamp fixture, a plurality of LEDs can be turned on by a built-in DC power source.

図６は実施例２に係る誘導音の発生手段を有するＬＥＤ照明装置の正面図である。
図６において、４０は誘導音発生回路、４１は管体に設置された振動素子であるピエゾ素子、４２は複数のＬＥＤである。FIG. 6 is a front view of the LED lighting device having the guide sound generating means according to the second embodiment.
In FIG. 6, reference numeral 40 denotes an induced sound generation circuit, 41 denotes a piezoelectric element that is a vibration element installed in a tubular body, and 42 denotes a plurality of LEDs.

この図６の構成において、実施例１の作用と同様に停電時には点灯することができ、ＬＥＤ照明装置を蛍光灯器具から取り外すとスイッチが入り、誘導音発生手段４０が駆動して、ピエゾ素子４１を振動させ、それが管体を振動させて大きな音を発生させ、停電時、警告音を発生して、異常を知らせる． In the configuration of FIG. 6, it can be turned on at the time of a power failure as in the operation of the first embodiment. When the LED lighting device is removed from the fluorescent lamp fixture, the switch is turned on, the guide sound generating means 40 is driven, and , Which vibrates the tube and generates a loud sound. In the event of a power failure, a warning sound is generated to indicate an abnormality.

音にも方向性を持たせることもでき、例えば、非常口に近いほど大きな音が発生するように構成するとか、非常口方向に音が流れるように点滅と同様に構成することが好ましい。
また、このような停電検知の機能を付けたものを示したが、明暗センサーや人感センサーなどを併設しても良く、より多機能なＬＥＤ照明装置とすることが可能である。The sound can also have directionality. For example, it is preferable that the sound is generated so that a louder sound is generated as it is closer to the emergency exit, or that the sound is flowed in the direction of the emergency exit.
Moreover, although what added the function of the power failure detection was shown, a light-and-dark sensor, a human sensor, etc. may be provided side by side, and it can be set as a more multifunctional LED lighting apparatus.

本発明に係るＬＥＤ照明装置はいままで蛍光灯が設置されたところにＬＥＤ照明装置を置き換えるのみで、ビルの管理産業の発展にも大いに役立つ。 The LED lighting device according to the present invention is very useful for the development of the building management industry by simply replacing the LED lighting device where a fluorescent lamp has been installed.
