Abstract

PROBLEM TO BE SOLVED: To solve a problem wherein a conventional emergency light is difficult to recognize the emergency light when a light-emitting surface of the emergency light is covered with damaged objects caused by damage on a house, and the emergency light having an electromagnetic relay and a complicated circuit structure may have damage on an internal circuit caused by shocks and may not function as the emergency light.SOLUTION: The emergency light uses a waterproof body housing formed by using a transparent resin, and a back cover. An internal light-emitting circuit of the emergency light is formed with a secondary battery, an electronic switch using a MOS-FET, a constant-current diode, a printed circuit board for mounting a simple circuit using a resistor. The emergency light can improve its reliability as illumination at the time of a disaster since edges of the printed circuit board are supported with a silicon rubber tube for shock protection and it uses a light-emitting diode for illumination.

Description

本発明は停電時に発光し、常時充電された防水の全方向照明に関する。The present invention relates to a waterproof omnidirectional illumination that emits light during a power failure and is always charged.

従来の常備灯は、一方向に照らすものであり、電磁リレーや複雑な回路を有するものである。Conventional standing lamps illuminate in one direction and have electromagnetic relays and complicated circuits.

上述の常備灯では、家屋の損傷により、常備灯の発光面が損傷物に覆われた場合、常備灯を認識することが難しい問題があった。The above-mentioned standing lamp has a problem that it is difficult to recognize the standing lamp when the light emitting surface of the standing lamp is covered with a damaged object due to damage to the house.

また、電磁リレーや複雑な回路構成を有するものは、衝撃により内部の回路を破損して、常備灯として機能しない問題があった。In addition, electromagnetic relays and those having a complicated circuit configuration have a problem that an internal circuit is damaged by an impact and does not function as a standing lamp.

本発明は、このような従来の構成が有していた問題を解決しようとするものであり、点灯用スイッチを半導体で構成することにより、耐衝撃性を向上させ、全方向に発光面を用いることで、災害時の視認性を向上させたものである。The present invention is intended to solve the problem of such a conventional configuration, and by configuring the lighting switch with a semiconductor, the impact resistance is improved and the light emitting surface is used in all directions. In this way, the visibility at the time of disaster is improved.

そして本発明は上記目的を達成するために、透明な樹脂を用いた防水の本体ハウジングと裏蓋を用い、内部の発光回路は、二次電池と、ＭＯＳ−ＦＥＴを用いた電子スイッチと、定電流ダイオードと、抵抗器を実装したプリント基板と、プリント基板の稜を、衝撃保護の為のシリコンゴムチューブで支持し、照明用に発光ダイオードで構成されたものである。In order to achieve the above object, the present invention uses a waterproof main body housing and back cover made of a transparent resin, and an internal light emitting circuit includes a secondary battery, an electronic switch using a MOS-FET, and a fixed circuit. A current diode, a printed circuit board on which a resistor is mounted, and a ridge of the printed circuit board are supported by a silicon rubber tube for impact protection, and are composed of a light emitting diode for illumination.

上述したように、本体ハウジングは透明な樹脂を使用しているために、全方向から、視認することができ、発光回路はＭＯＳ−ＦＥＴを用いた電子スイッチと定電流ダイオードと抵抗器で構成されたプリント基板で構成されており、複数個の発光用ＬＥＤは独立して定電流で駆動しているため、常備灯のＬＥＤが損傷し、ショート状態に陥っても、損傷のないＬＥＤの発光に影響を及ぼさないため、信頼性の高い常備灯を提供できる。As mentioned above, since the main body housing uses a transparent resin, it can be seen from all directions, and the light emitting circuit is composed of an electronic switch using a MOS-FET, a constant current diode, and a resistor. Since a plurality of light emitting LEDs are independently driven with a constant current, the LED of the standing lamp is damaged, and even if it falls into a short circuit, the LED can emit light without damage. Since it has no effect, it can provide a highly reliable standing lamp.

また、本発明は防水構造にしているため、水没しても常備灯として機能することができる。In addition, since the present invention has a waterproof structure, it can function as a standing lamp even when submerged.

本発明の回路図Circuit diagram of the present invention

以下、本発明の実施の形態を図１、図２に基づいて説明する。Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

図１においては、透明な樹脂を用いた本体ハウジング１と防水のシーリング２をした透明な樹脂を用いた裏蓋３。In FIG. 1, a main body housing 1 using a transparent resin and a back cover 3 using a transparent resin with a waterproof seal 2.

ハウジング中央に、二次電池５と二次電池５の充電回路と停電時にＬＥＤ４を発光させるための電子スイッチと、ＬＥＤ４の発光用に定電流ダイオードが実装されているプリント基板６と、プリント基板６を衝撃から保護するためのシリコンゴムチューブ７でプリント基板６の稜を保護し、それらを中心に、その回りに配置した、停電時に照明として発光させる複数個のＬＥＤ４で構成される。In the center of the housing, a secondary battery 5, a charging circuit for the secondary battery 5, an electronic switch for causing the LED 4 to emit light in the event of a power failure, a printed circuit board 6 on which a constant current diode is mounted for light emission of the LED 4, and the printed circuit board 6 The ridges of the printed circuit board 6 are protected by a silicon rubber tube 7 for protecting the battery from impact, and the LED 4 is arranged around the printed circuit board 6 so as to illuminate as a lighting in the event of a power failure.

この二次電池５には充電回路が簡便にできるニッケルカドニウム電池、ニッケル水素電池等が使用される。As the secondary battery 5, a nickel cadmium battery, a nickel hydride battery, or the like whose charging circuit can be simplified is used.

二次電池５を充電するために、交流電源ＡＣはＡＣ／ＤＣアダプターに入力され、ＡＣ／ＤＣアダプター内で直流にして本体ハウジングコネクター８に接続される。In order to charge the secondary battery 5, the AC power source AC is input to the AC / DC adapter, and is converted into a direct current within the AC / DC adapter and connected to the main body housing connector 8.

本体ハウジングの入力コネクタ８は、本体ハウジング１の内部にて、防水のためにシリコン樹脂等を使用して防水処理をされている。The input connector 8 of the main body housing is waterproofed using silicon resin or the like for waterproofing inside the main body housing 1.

本体ハウジング１に入力された直流電圧は、二次電池５の充電回路と停電時にＬＥＤ４を発光させるための電子回路が実装されているプリント基板６に接続される。The DC voltage input to the main body housing 1 is connected to a printed circuit board 6 on which a charging circuit for the secondary battery 5 and an electronic circuit for causing the LED 4 to emit light in the event of a power failure are mounted.

図２においては、回路図を説明する。In FIG. 2, a circuit diagram will be described.

二次電池５を充電するために、交流電源ＡＣはＡＣ／ＤＣアダプターのトランスＴ１の一次巻線Ｐに入力され、その二次巻線Ｓから所定の電圧に変換されて出力され、整流器ＢＤにて整流された後、コンデンサＣ１にて平滑されて直流出力として、本体ハウジング１の入力コネクタ８に接続される。勿論ＡＣ／ＤＣアダプターはトランスを用いたものに限らず、スイッチング方式のＡＣ／ＤＣアダプターでも構わない。In order to charge the secondary battery 5, the AC power source AC is input to the primary winding P of the transformer T1 of the AC / DC adapter, converted from the secondary winding S to a predetermined voltage, and output to the rectifier BD. After being rectified, it is smoothed by the capacitor C1 and connected to the input connector 8 of the main body housing 1 as a direct current output. Of course, the AC / DC adapter is not limited to one using a transformer, and may be a switching AC / DC adapter.

入力コネクタ８から入力された電圧は、抵抗器９に接続され、抵抗器９はダイオード１０のアノードに接続され、ダイオード１０のカソードは定電流ダイオード１１のアノードに接続され、定電流ダイオード１１のカソードは直列接続された二次電池５の正極と、電子スイッチとして使用するＰチャンネルＭＯＳ−ＦＥＴ１２のソースに接続される。The voltage input from the input connector 8 is connected to the resistor 9, the resistor 9 is connected to the anode of the diode 10, the cathode of the diode 10 is connected to the anode of the constant current diode 11, and the cathode of the constant current diode 11. Are connected to the positive electrode of the secondary battery 5 connected in series and the source of the P-channel MOS-FET 12 used as an electronic switch.

ＰチャンネルＭＯＳ−ＦＥＴ１２のゲートはダイオード１０のアノードに接続され、ＰチャンネルＭＯＳ−ＦＥＴ１２のドレインは定電流ダイオード１３のアノードに接続され、定電流ダイオード１３のカソードからＬＥＤ４のアノードに接続されており、ＬＥＤ４のカソードから直列接続された二次電池５の負極に接続されている。The gate of the P-channel MOS-FET 12 is connected to the anode of the diode 10, the drain of the P-channel MOS-FET 12 is connected to the anode of the constant current diode 13, and the cathode of the constant current diode 13 is connected to the anode of the LED 4. The cathode of the LED 4 is connected to the negative electrode of the secondary battery 5 connected in series.

ＡＣ／ＤＣアダプターから電圧が供給されているときは、ダイオード１０と定電流ダイオード１１から定電流で、二次電池５に常時充電されている。When the voltage is supplied from the AC / DC adapter, the secondary battery 5 is always charged with a constant current from the diode 10 and the constant current diode 11.

ＡＣ／ＤＣアダプターの出力電圧の正極側には、電子スイッチとして用いているＰチャンネルＭＯＳ−ＦＥＴ１２のゲートが接続されているため、充電時にはＰチャンネルＭＯＳ−ＦＥＴ１２のゲート電位は、ＰチャンネルＭＯＳ−ＦＥＴ１２のソース電位以上になり、電子スイッチとして使用するＰチャンネルＭＯＳ−ＦＥＴ１２はオフしてＬＥＤ４には電流は流れない。Since the gate of the P-channel MOS-FET 12 used as an electronic switch is connected to the positive side of the output voltage of the AC / DC adapter, the gate potential of the P-channel MOS-FET 12 during charging is the P-channel MOS-FET 12. The P channel MOS-FET 12 used as an electronic switch is turned off and no current flows through the LED 4.

停電時にＡＣ／ＤＣアダプターから電流の供給が停止すると、抵抗器９がＡＣ／ＤＣアダプターの出力電圧を０Ｖになるように放電するため、ＰチャンネルＭＯＳ−ＦＥＴ１２のゲート電位は０Ｖになり、直列接続された二次電池５の正極に接続されているＰチャンネルＭＯＳ−ＦＥＴ１２のソース電位とは電位差を持つことにより、ＰチャンネルＭＯＳ−ＦＥＴ１２はオンするので、二次電池５から電流がＰチャンネルＭＯＳ−ＦＥＴ１２を通して、定電流ダイオード１３を流れ、定電流でＬＥＤ４を発光させる。When the supply of current from the AC / DC adapter stops during a power failure, the resistor 9 discharges so that the output voltage of the AC / DC adapter becomes 0V. Therefore, the gate potential of the P-channel MOS-FET 12 becomes 0V and is connected in series. Since the P-channel MOS-FET 12 is turned on by having a potential difference from the source potential of the P-channel MOS-FET 12 connected to the positive electrode of the rechargeable secondary battery 5, current flows from the secondary battery 5 to the P-channel MOS- Through the FET 12, the constant current diode 13 flows, and the LED 4 emits light with a constant current.

ダイオード１０は、停電時に二次電池５から電流が定電流ダイオード１１を通して抵抗器９に接続されているＰチャンネルＭＯＳ−ＦＥＴ１２のゲート電位が０Ｖから正の電位に上昇してＰチャンネルＭＯＳ−ＦＥＴ１２がオフする事を防ぐ。In the diode 10, the gate potential of the P-channel MOS-FET 12 connected to the resistor 9 through the constant current diode 11 from the secondary battery 5 rises from 0 V to a positive potential at the time of a power failure, and the P-channel MOS-FET 12 becomes Prevents turning off.
