Abstract

PROBLEM TO BE SOLVED: To provide an emergency lighting fixture in which an LED lamp can be lighted regardless of whether it is normal time or emergency time.SOLUTION: An emergency lighting fixture comprises a normal power supply circuit which supplies AC power from a commercial power supply to a lamp, and an emergency power supply circuit which supplies DC power from a storage battery to the lamp while converting into AC power. The emergency lighting fixture normally lights the lamp using the normal power supply circuit and lights the lamp by switching to the emergency power supply circuit at the time of emergency. The emergency lighting fixture is further provided with a circuit for lighting the LED lamp so that even an LED lamp can be lighted using power from the storage battery.

Description

本発明は、既存の非常灯、誘導灯などの非常用照明器具の蛍光ランプを交流対応型のＬＥＤランプに代える際に用いて好適な非常用照明器具の点灯回路に関するものである。   The present invention relates to a lighting circuit for an emergency lighting fixture that is suitable for use in replacing the fluorescent lamp of an existing emergency lighting fixture such as an emergency light or a guide light with an AC-compatible LED lamp.

現在普及している非常灯や誘導灯は、常時は商用電源からの電力を用いて蛍光ランプを点灯させ、停電など非常時には蓄電池を電源に使用してＡＣ／ＤＣインバーターを用いて直流を交流に変換させて蛍光ランプを点灯させるものが一般的である。しかしながら、近年、地球温暖化防止に関する意識の高まりから、蛍光ランプに代えて消費電力の少ない交流対応型のＬＥＤランプを用いることが普及しつつある。   The emergency lights and guide lights that are currently in widespread use always turn on the fluorescent lamps using the power from the commercial power supply. In the event of an emergency such as a power outage, the storage battery is used as the power source and the AC / DC inverter is used to convert the direct current to alternating current. In general, the fluorescent lamp is turned on after conversion. However, in recent years, the use of AC-compatible LED lamps with low power consumption instead of fluorescent lamps is becoming widespread due to the growing awareness of global warming prevention.

この意識の高まりは、非常用照明器具にも及び、従来の蛍光ランプに代えて交流対応型のＬＥＤランプを使用する動きが出てきている。この種の交流対応型のＬＥＤランプは既に市販されており、最初から整流回路を内蔵しているので、蛍光ランプをＬＥＤランプに代えるだけでＬＥＤランプの点灯が可能である。   This heightened awareness extends to emergency lighting fixtures, and there is a movement to use AC-compatible LED lamps instead of conventional fluorescent lamps. This type of AC-compatible LED lamp is already on the market and has a built-in rectifier circuit from the beginning. Therefore, the LED lamp can be turned on only by replacing the fluorescent lamp with the LED lamp.

しかるに、停電時などの非常時には蓄電池などの直流電源をＡＣ／ＤＣインバーターを用いて交流電源に変換させて交流対応型のＬＥＤランプに印加しても、当該ＬＥＤランプは点灯しない場合がある。これは、ＡＣ／ＤＣインバーターを用いて変換させた交流の波形が矩形波となることから、蛍光ランプであると負荷抵抗があるので点灯は可能であるが、交流対応型のＬＥＤランプの場合にはこの矩形波に含まれる高周波ノイズによって、ＬＥＤランプ内部のスイッチング制御に影響を与え点灯しなくなるものと思われる。   However, even when a DC power source such as a storage battery is converted into an AC power source using an AC / DC inverter and applied to an AC-compatible LED lamp in an emergency such as a power failure, the LED lamp may not be lit. This is because the alternating current waveform converted using the AC / DC inverter becomes a rectangular wave, so that it is possible to light the fluorescent lamp because there is a load resistance, but in the case of an AC compatible LED lamp. It seems that the high frequency noise included in this rectangular wave affects the switching control inside the LED lamp and does not light up.

本発明が解決しようとする課題は、常時・非常時にかかわらず交流対応型のＬＥＤランプを点灯させることができる非常用照明器具の点灯回路を提供することにある。   The problem to be solved by the present invention is to provide a lighting circuit for an emergency lighting fixture capable of lighting an AC LED lamp regardless of whether it is always or in an emergency.

上記課題を解決するために、本発明は、商用電源からの交流電力をランプに供給する常時用電源回路と、蓄電池からの直流電力を交流電力に変換してランプに供給する非常時用電源回路とを備え、常時は常時用電源回路を使用して非常時は非常時用電源回路に切り替えてランプを点灯させる非常用照明器具において、前記ランプを交流対応型のＬＥＤランプとし、前記非常時用電源回路を構成するＡＣ／ＤＣインバーターの後にＬＥＤランプ点灯用回路を設けたことを特徴とする。
その際に、本発明は、前記ＬＥＤランプ点灯用回路をローパスフィルタで構成するものである。 In order to solve the above-described problems, the present invention provides a constant power circuit for supplying AC power from a commercial power source to a lamp, and an emergency power circuit for converting DC power from a storage battery into AC power and supplying the lamp to the lamp. In an emergency lighting fixture that always uses a power supply circuit for normal use and switches to an emergency power supply circuit in an emergency to light the lamp, the lamp is an AC-compatible LED lamp, and the emergency use An LED lamp lighting circuit is provided after the AC / DC inverter constituting the power supply circuit.
In that case, this invention comprises the said LED lamp lighting circuit by a low-pass filter.

本発明の非常用照明器具によれば、ＡＣ／ＤＣインバーターの後に設けたＬＥＤランプ点灯用回路により、蓄電池から変換した交流電源の波形を正弦波に近くして、停電などの非常時においてもＬＥＤランプを点灯させることができるものである。   According to the emergency lighting device of the present invention, the LED lamp lighting circuit provided after the AC / DC inverter makes the waveform of the AC power source converted from the storage battery close to a sine wave, so that the LED can be used even in an emergency such as a power failure. The lamp can be turned on.

本発明の非常用照明器具の実施形態を例示するブロック図である。It is a block diagram which illustrates embodiment of the emergency lighting fixture of this invention.

以下、本発明の実施形態につき添付図面を参照して説明する。
図１に示すように、この実施形態の非常用照明器具１は、商用電源２からの電力により点灯するものとして市販されている交流対応型のＬＥＤランプ３と、このＬＥＤランプ３を点灯させる非常灯ユニット４と、ＬＥＤランプ３が挿着されるソケット５と、安定器６と、グロースタータ７と、消灯スイッチ８、蓄電池９とを備えている。ソケット５には、ＬＥＤランプ３が挿着されている。ＬＥＤランプ３は、また、電源から供給される交流電力を直流電力に変換してＬＥＤランプに供給する整流回路１０を内蔵している。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, an emergency lighting apparatus 1 of this embodiment includes an AC-compatible LED lamp 3 that is marketed as being turned on by power from a commercial power supply 2 and an emergency lamp that lights the LED lamp 3. A lamp unit 4, a socket 5 into which the LED lamp 3 is inserted, a ballast 6, a glow starter 7, a turn-off switch 8, and a storage battery 9 are provided. The LED lamp 3 is inserted into the socket 5. The LED lamp 3 also has a built-in rectifier circuit 10 that converts AC power supplied from a power source into DC power and supplies it to the LED lamp.

非常灯ユニット４は、商用電源２からの交流電力をＬＥＤランプ３に供給する常時用電源回路１１と、蓄電池９からの直流電力を交流電力に変換してＬＥＤランプ３に供給する非常時用電源回路１２とを備えており、常時は常時用電源回路１１を使用してＬＥＤランプ３を点灯させ、非常時は非常時用電源回路１２に切り替えてＬＥＤランプ３を点灯させる。非常時用電源回路１２は、蓄電池９からの電力を用いてＬＥＤランプ３を点灯させるためのＡＣ／ＤＣインバーター１２Ａと、蓄電池９からの電力を用いてＬＥＤランプ３を点灯させるための、例えばローパスフィルタから成るＬＥＤランプ点灯用回路１２Ｂとを備えている。   The emergency light unit 4 has a constant power supply circuit 11 that supplies AC power from the commercial power supply 2 to the LED lamp 3 and an emergency power supply that converts DC power from the storage battery 9 into AC power and supplies it to the LED lamp 3. The LED lamp 3 is always turned on using the power supply circuit 11 for normal use, and the LED lamp 3 is turned on by switching to the power supply circuit 12 for emergency use in an emergency. The emergency power supply circuit 12 includes an AC / DC inverter 12A for lighting the LED lamp 3 using the power from the storage battery 9, and a low pass for lighting the LED lamp 3 using the power from the storage battery 9, for example. And an LED lamp lighting circuit 12B made of a filter.

したがって、この非常用照明器具１は、常時は商用電源２からの交流電力を常時用電源回路１１を介してＬＥＤランプ３に供給する。ＬＥＤランプ３として蛍光ランプを使用している場合、グロースタータ７が作動することにより点灯が開始され、常時用電源回路１１から供給される交流電力によって点灯状態が維持される。ランプとしてＬＥＤランプ３を使用している場合、グロースタータ７は作動せず、商用電源２から常時用電源回路１１を介して供給される交流電力をＬＥＤランプ３内の整流回路１０で直流電力に変換してＬＥＤランプ３内のＬＥＤ３ａに供給することにより点灯が行われる。   Therefore, the emergency lighting apparatus 1 always supplies the AC lamp from the commercial power source 2 to the LED lamp 3 through the constant power source circuit 11. When a fluorescent lamp is used as the LED lamp 3, lighting is started by operating the glow starter 7, and the lighting state is maintained by AC power supplied from the power supply circuit 11 for constant use. When the LED lamp 3 is used as the lamp, the glow starter 7 does not operate, and the AC power supplied from the commercial power supply 2 through the power supply circuit 11 is converted into DC power by the rectifier circuit 10 in the LED lamp 3. Lighting is performed by converting and supplying the LED 3 a in the LED lamp 3.

非常時においては、蓄電池９からの直流電力が非常時用電源回路１２で交流電力に変換されてＬＥＤランプ３に供給される。ＬＥＤランプ３として蛍光ランプを使用している場合、非常時用電源回路１２内の蛍光ランプ点灯用回路１２Ａが作動することにより当該蛍光ランプの点灯状態が維持される。ランプとしてＬＥＤランプ３を使用している場合、非常時用電源回路１２内のＬＥＤランプ点灯用回路１２Ｂが作動することによりＬＥＤランプ３の点灯状態が維持される。   In an emergency, the DC power from the storage battery 9 is converted into AC power by the emergency power supply circuit 12 and supplied to the LED lamp 3. When a fluorescent lamp is used as the LED lamp 3, the fluorescent lamp lighting circuit 12A in the emergency power supply circuit 12 is activated to maintain the lighting state of the fluorescent lamp. When the LED lamp 3 is used as the lamp, the LED lamp lighting circuit 12B in the emergency power supply circuit 12 is activated, so that the lighting state of the LED lamp 3 is maintained.

このように、この非常用照明器具１によれば、通常の蛍光ランプを点灯させる非常時用電源回路１２にＬＥＤランプ点灯用回路１２Ｂを備えたことにより、ランプとしてＬＥＤランプ３を用いた場合においても、常時・非常時にかかわらずＬＥＤランプ３を点灯させることができるものである。   As described above, according to the emergency lighting apparatus 1, when the LED lamp lighting circuit 12B is provided in the emergency power supply circuit 12 for lighting a normal fluorescent lamp, the LED lamp 3 is used as a lamp. However, the LED lamp 3 can be lit regardless of whether it is always or in an emergency.

以上説明したように、本発明によれば、とくに既存の蛍光ランプを用いた非常用照明器具において、蛍光ランプをＬＥＤランプに代えた際に好適に用いられる点灯回路となるものである。   As described above, according to the present invention, particularly in an emergency lighting fixture using an existing fluorescent lamp, the lighting circuit is suitably used when the fluorescent lamp is replaced with an LED lamp.
