Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency lighting device which detects a power failure of a commercial AC power source and lights an emergency lamp using a battery.

[0002]

2. Description of the Related Art As an apparatus for lighting an emergency lamp in an emergency, for example, there is a lighting fixture with a disaster prevention device disclosed in Japanese Utility Model Laid-Open No. 164115/1983. As shown in FIG. 4 and FIG. 5, this is a lighting fixture with a disaster prevention device that can compactly store disaster prevention devices such as emergency lights or earthquake detectors using a hook ceiling. 1, a hook 2 having a disaster prevention device and a hook 2 at the center of the lower surface, which is hooked to cover the hook ceiling pedestal 1, and the lighting unit main body 8 is supported by the hook of the support 2. The ceiling cover 7 is adapted to be hooked.

[0003]

In the above-mentioned conventional apparatus, the existing hook ceiling can be used to support the support, and the support can be mounted compactly and easily without any special structure. However, on the other hand, in the case of attaching the luminaire main body 8 that is the main illuminator in normal times, the luminaire to be attached is as shown in FIG. 4 because the support 2 exists so as to cover the outer periphery of the hook ceiling.
It is limited to the hanging type lighting fixture as shown in (4), and it is naturally impossible to support various forms of lighting fixture main body.

Further, in this device, although it is possible to turn on the emergency light when the seismic detector or smoke detector is activated, it is possible that the commercial power supply is cut off, that is, in an emergency. Naturally, there was a drawback that the emergency light did not function during the expected power outage.

The present invention has been made in order to solve the above-mentioned problems, and firstly, when the commercial power supply is cut off in an emergency, that is, when a power failure occurs. In some cases, it is to provide an emergency luminaire that detects this and uses an internal battery to light an emergency lamp.

Secondly, not only when the main body of the lighting fixture is a hanging type, but also when the main body of the lighting fixture is directly attached to the ceiling surface and used. To take into consideration.

Thirdly, it is also taken into consideration that the emergency lighting equipment can be easily removed at the time of exchanging the built-in battery and the emergency light source, and the replacement work can be easily performed at hand.

Fourthly, the emergency light source device constituting the emergency lighting device has a primary battery and an emergency lamp which is lit by receiving power from the battery.

Fifthly, the emergency light source device is provided with a plurality of emergency lamps electrically connected in parallel.

Sixth, the emergency light source device has a built-in recognition device for displaying and notifying the life of the primary battery.

[0011]

An emergency lighting apparatus according to the present invention has a detachable connecting portion at one end which engages with a power feeding portion provided on a ceiling or the like, and extends horizontally from this connecting portion. On the other end side, a substantially flat plate-shaped support body having a built-in power failure detector for detecting a power failure, and the lower surface side of the above-mentioned power failure detector of this support receives a signal from the power failure detector. It is equipped with an emergency light source that lights up in the event of a power failure.

Further, a locking portion for mounting a lighting fixture for controlling main illumination in normal time is provided at a facing lower portion of a connecting portion provided at one upper end of the support.

Further, the emergency light source device is detachably provided on the lower surface side of the power failure detector of the support, and is configured to internally include the primary battery and the emergency lamp which is lit by receiving power supply from the primary battery. In addition, the emergency lamp is configured to have a plurality of lamps electrically connected in parallel.

[0014]

According to the present invention, it is possible to provide an emergency lighting device capable of turning on the emergency lamp only in case of a power failure, and it is possible to deal with various lighting fixture main bodies serving as main lighting. it can.

In addition, the emergency lighting unit can be easily removed when the built-in battery or the emergency lamp is replaced, and a plurality of emergency lamps electrically connected in parallel are provided, so that the emergency lamp is If something goes wrong, emergency lighting can be secured by another emergency lamp connected in parallel.

Further, when the built-in primary battery has reached the end of its life, this can be easily recognized by the notification means.

[0017]

Embodiments of the present invention will be described below with reference to FIGS. Embodiment 1 In FIGS. 1 and 2, reference numeral 1 is a hook ceiling pedestal fixed to a ceiling surface or the like, 10 is a hook claw 6 which is hooked on the hook ceiling ceiling pedestal 1 at one end of the upper surface, and at the other end. A support body having a power failure detector 11 for detecting a power failure therein, 13 is an emergency lighting device portion, and a hook 1 is provided on a lower surface portion of the power failure detector.
2 has a built-in primary battery 14 hooked on the support 10 to turn on the emergency lamp 15 in the event of a power failure, and an LED 16 that is a recognition device that detects the voltage drop of this battery and notifies it to the outside. It is composed of a transparent cover 17 for covering.

Reference numeral 7 is a hook ceiling cover formed by suspending a main body 8 of a lighting fixture for normal lighting. A hook portion provided on a support 10 hooks a hook claw 9 on an upper portion of the hook ceiling cover. It is designed to be configured.

As described above, according to the present invention, the support having the power failure detector inside is hooked on the hook ceiling pedestal, and the lighting fixture main body is provided at the other end on the hook portion at one end of the support. Since the structure is designed to support the emergency lighting device that lights up on the bottom surface of the power failure detector, the main body of the lighting fixture and the emergency lighting device that lights up during an emergency, that is, a power failure are supported. It is attached integrally via.

Example 2 In Example 1 above, a hanging type lighting fixture was illustrated as the main illumination, but as shown in FIG. 3, the support body has a hook portion connected to the power source at one end and Since it is configured to support the emergency lighting device on the other end portion that extends, it can be easily applied by arranging it on the side surface of the fixture directly attached to the ceiling surface, It enables application to lighting equipment.

[0021]

As described above, according to the present invention, since the emergency lighting device can be easily attached to and detached from the support, the battery and the emergency lamp can be easily replaced. In addition, since multiple emergency lamps are electrically connected in parallel, even if one emergency lamp is disconnected in an emergency and there is a defect, the other emergency lamps in parallel are turned on. Function is not impaired. Further, the life of the battery can be detected and notified by a recognition device such as an LED to prompt battery replacement. Furthermore, by using the battery as a primary battery, there are advantages such as good availability at the time of replacement and inexpensive purchase.
