Description

  The present invention relates to an LED lighting device, and more particularly to a multifunctional and rechargeable battery-housing LED lighting device that can be used as general lighting, emergency lighting, and portable lighting.

  In recent years, instead of conventional incandescent bulbs and fluorescent lamps, LEDs that consume very little power and have a very long service life are becoming widespread, and the penetration rate is rapidly increasing.

  For this reason, applications using light emission of LEDs are being studied, and lighting devices having multiple functions using LEDs have been developed.

  As an example, the following patent documents are disclosed.

  Japanese Patent Application Laid-Open No. 2005-116379 disclosed in Japanese Patent Application Laid-Open No. 2005-116379 describes a flashlight LED unit that can be easily changed from an existing light bulb type flashlight using a light bulb as a light emitter to a flashlight using a light emitting diode as a light emitter. Is disclosed.

  Japanese Patent Application Laid-Open No. 2006-331880 of Patent Document 2 discloses a portable LED lighting device having a function that can be used as an all-in-one lamp as needed in addition to a function as a signal lamp.

  Japanese Patent Application Laid-Open No. 2009-105020 of Patent Document 3 mounts a plurality of LEDs in a cylinder that can be attached to a fluorescent lamp fixture, and causes the LEDs to emit light with a DC power source built in when a power failure is detected, thereby generating a guide sound. Are disclosed.

  However, if the location of the flashlight type or portable LED lighting device itself of Patent Document 1 to Patent Document 2 is unknown, it cannot be used immediately in the event of an emergency, and even during a power failure at night. Since there was a problem that it could not be searched and was extremely inconvenient, Japanese Patent Application Laid-Open No. 2009-105020 of Patent Document 3 is a fluorescent lamp type LED lighting device. It was difficult to handle, and it was impossible to use it like a flashlight in an emergency. Accordingly, it has been an object of the present invention to solve these problems.

The present invention solves the above problems by the following configuration.
That is, the present invention is an illuminating device using an LED as a light emitting light source, and can be used as general illumination by attaching a base to a stationary socket. The power supplied from an AC power source is supplied via an AC / DC converter. A rechargeable battery is housed, and when the AC power supply is interrupted due to a power failure or the like, the power is switched from the battery via the control circuit unit so that the LED emits light and functions as emergency lighting. When the illuminating device main body is removed from the socket and used, the LED is turned on by switching to electric power from the battery, and the light emission of the LED can be switched by a manual switch provided in the LED storage case. A flashlight that is configured to function as an electric light and that can be removed from a stationary socket And a cylindrical portion that functions as a handle that is easily extended by being extended from the inside of the LED storage case, and is configured to store a rechargeable battery in the cylindrical portion. A device is provided.

  As described above, the LED lighting device according to the present invention is a multi-functional and rechargeable battery storage LED lighting device that can be used as general lighting, emergency lighting, and portable lighting. At times, it is possible to switch the power from the storage battery via the control circuit unit to make the LED emit light. is there.

  Further, even when the room is immediately pulled out due to the occurrence of an earthquake or the like, the LED lighting device body can be easily detached from the socket and used like a normal flashlight, which is convenient when moving in a dark environment.

  Furthermore, the LED lighting device of the present invention has a cylindrical portion that can be extended from the inside of the LED storage case when the LED lighting device is detached from a stationary socket and used as a flashlight. It can function as an easy handle.

  It is a perspective view of a LED lighting device.   It is a perspective view of the LED lighting apparatus of the state which extended the cylindrical part.   It is sectional drawing of a LED lighting apparatus.   FIG. 4 is a sectional view taken along line AA in FIG. 3.   It is a schematic diagram of the control circuit part of a LED lighting device.

    DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings.

  The LED illumination device of the present invention is an illumination device that uses an LED 19 as a light source, and can be used as general illumination by being attached to a stationary socket 16 as shown in FIG. 1, as shown in FIGS. The electric power supplied from the AC power source is charged into the rechargeable battery 21 via the AC / DC converter 20.

  Usually, even in a state where the base portion 15 is screwed into the socket 16, the LED is caused to emit light by the DC power from the battery 21.

  However, when the AC power supply is interrupted due to a power failure or the like, the power is automatically switched to only the power from the battery 21 via the control circuit unit 22 so that the LED emits light and functions as emergency lighting.

  As shown in FIG. 2, when the LED lighting device body 1 is used after being removed from the socket 16, the LED 19 is caused to emit light by switching to the power from the battery 21, and the LED 19 is operated by the manual switch 13 provided in the LED storage case 12. It is configured to function as a normal flashlight so that the light emission can be switched.

  Further, as shown in FIGS. 2 to 3, when used as a flashlight by being removed from the stationary socket 16, the tubular portion 17 is extended from the inside of the LED storage case 12 so as to function as an easy handle. It is configured.

  As shown in FIGS. 2, 3, and 4, a protrusion 18 is integrally provided on the side surface of the cylindrical portion 17, and the protrusion 18 is provided at the lower end portion 14 of the LED storage case as shown in FIG. 4. The cylindrical portion is rotated when the cylindrical portion 17 is extended, and the lead wire or the like (not shown) is prevented from being damaged.

  Normally, when the base 15 is screwed into the socket 16 and fixed, the power supplied from the AC power source is charged to the battery 21 via the AC / DC converter 20 and the LED 19 is lit by the DC power. Yes.

  However, when the AC power supply is interrupted due to a power failure or the like, the control circuit unit 22 detects the interruption of the AC power supply and automatically switches to only the power from the battery 21 to cause the LED 19 to emit light and function as emergency lighting. It is configured as follows.

  As described above, when the LED lighting device main body 1 is used by being removed from the socket 16, the manual switch 13 can be used like a normal flashlight.

  When the energization of the AC power source is restored, the battery 21 can be easily charged by reattaching the base portion 15 to the socket 16.

  In addition, even if it is an LED stand for lighting that uses only power from the battery even if there is no AC power supply connection, it is possible to incorporate an earthquake detection sensor and turn it on automatically, and to operate these operations by remote control It is also possible.

  The present invention is configured as described above, and can function as an emergency light or a flashlight at the time of a power failure at night or due to a sudden earthquake, etc. Since it is extremely convenient and useful, industrial applicability is great.
