Description

本発明は、電球形ＬＥＤランプに関する。   The present invention relates to a bulb-type LED lamp.

電球形ＬＥＤランプは電球口金ソケットに装着し、電球口金ソケットを通じて点灯回路に電力を供給して、ＬＥＤを点灯している。したがって電球口金ソケットからの電力供給が停止するとランプが消灯する。夜間時の停電等で電力の供給が停止してしまうと、あたり一面暗闇になり危険である。   The bulb-type LED lamp is mounted on a bulb base socket, and power is supplied to the lighting circuit through the bulb base socket to light the LED. Therefore, the lamp is turned off when the power supply from the bulb base socket is stopped. If the power supply is stopped due to a power outage at night, etc., it will be dark and dangerous.

特開２００１−２４３８０７号 例えば特許文献１に記載されているＬＥＤ電球は、電球代替として使用できる構造となっているが、バッテリーを具備しておらず供給電力の切替えが出来ない為、停電等で商用電源からの電力の供給が停止した時、ランプが不点灯となってしまう。また、バッテリーを具備していない為、電球口金ソケットから取り外して持ち運び可能な照明装置として使用出来ない。For example, the LED bulb described in Japanese Patent Laid-Open No. 2001-243807 has a structure that can be used as an alternative to a bulb, but since it does not have a battery and cannot switch power supply, When the supply of power from the commercial power supply is stopped, the lamp is not lit. Moreover, since it does not have a battery, it cannot be used as a lighting device that can be removed from the bulb base socket and carried.

本発明が解決しようとする課題は、停電等で電力供給が停止時でも安定した照明を提供し、電球口金ソケットから取り外し、持ち運び可能な光源として使用することもできる電球形ＬＥＤランプを提供する事にある。   The problem to be solved by the present invention is to provide a light bulb-type LED lamp that provides stable lighting even when power supply is stopped due to a power failure or the like, and can be removed from a light bulb base socket and used as a portable light source. It is in.

上記問題を解決するため、少なくとも一つ以上のＬＥＤと点灯回路と少なくとも点灯回路を被せるケースと電球口金を具備した電球形ＬＥＤランプにおいて、ケース内にバッテリーを具備し、ケースには電力供給を切り替えるスイッチを具備している。前記スイッチによりＬＥＤへの電力供給を前記バッテリーと商用電源への切替えが可能な構成とした。   In order to solve the above problem, in a bulb-type LED lamp having at least one LED, a lighting circuit, a case that covers at least the lighting circuit, and a bulb base, a battery is provided in the case, and the power supply is switched to the case. A switch is provided. The power supply to the LED can be switched between the battery and the commercial power source by the switch.

本発明によれば、内部にバッテリーを内蔵し、電力供給を切り替えることの出来るスイッチを具備することで停電等の商用電源からの電力供給停止時にでもバッテリーから電力供給ができ、点灯可能な照明装置を実現できる。また、電球口金ソケットから取り外し、持ち運び可能な照明装置として使用出来る。   According to the present invention, an illuminating device that can be lit by supplying power from a battery even when power supply from a commercial power source such as a power failure is stopped by providing a switch with a built-in battery and switching power supply. Can be realized. It can also be removed from the bulb base socket and used as a portable lighting device.

図１において１はケースで、その一端には口金２が取り付けられている。また、ケースには電力供給を切り替えるスイッチ３、発光部１３が取り付けられている。ケース１の内部は図２を用いて説明する。１０はAC/DCコンバータ部でダイオードブリッジ８、平滑コンデンサ９から構成されている。１６は点灯回路部でスイッチ部６、商用電源用点灯回路１１、バッテリー用点灯回路１２から構成されている。１３は発光部でＬＥＤ素子５より構成される、７は商用電源、４はバッテリーである。   In FIG. 1, 1 is a case, and a base 2 is attached to one end thereof.

本発明品は上記した通りスイッチ部６の切替えにより電力供給をバッテリー４と商用電源７に切り替えることが可能である。通常時は電球口金ソケットから一般電球と同様に使用でき、停電等により商用電源７からの電力供給が停止した時に、非常用の光源として使用することが出来る。またバッテリーは内蔵されているため、電球口金ソケットから取り外して、持ち運び可能な照明装置として使用出来る。   The product of the present invention can switch the power supply to the battery 4 and the commercial power source 7 by switching the switch unit 6 as described above. Normally, it can be used in the same manner as a general light bulb from a light bulb base socket, and can be used as an emergency light source when power supply from the commercial power source 7 is stopped due to a power failure or the like. Since the battery is built-in, it can be removed from the bulb base socket and used as a portable lighting device.

商用電源用点灯回路１１とバッテリー点灯回路１２から異なった出力を発信することにより発光部１３の明るさを変えることができる。   The brightness of the light emitting unit 13 can be changed by transmitting different outputs from the commercial power supply lighting circuit 11 and the battery lighting circuit 12.
