Abstract

PURPOSE: To secure illumination near at hand in case of emergent service interruption, by constituting a luminaire so that a switch is turned off while a globe-shaped main body is in its inverted state and the switch is turned on when the main body rights itself under the influence of the center of gravity located in its bottom after having tumbled due to a big shake. CONSTITUTION: A luminaire is constituted such that a container part 2 containing a battery 3 movably up/down is installed in a globe-shaped main body 1 having centers of gravity on its bottom part and top part, a socket part 4 for an electric bulb 5 is provided thereon, a metal coil spring 6 attached to the lower part of the socket part 4 is caused to come into contact with the positive electrode of the battery 3, and the electric bulb is lighted in the normal raised state of the globe-shaped main body 1 while putting out in the inverted state thereof. When not using, the top part is so put as coming to a lower side, which is in the inverted state. The globe-shaped main body 1, having tumbled due to a big shake such as an earthquake, rights itself to a normal raised state because the center of gravity thereof including the battery is concentrated on the lower half part of the globe body, thereby the battery 3 falls within the container part 2, a switch is caused to become on, and the electric bulb 5 is automatically lighted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is equipped with a battery, a light bulb, etc. in a spherical body made of a transparent or translucent material so that the bulb can be turned on when the spherical body is in a normal standing state and turned off when it is inverted. It is related to the lighting equipment.

[0002]

2. Description of the Related Art Conventionally, a flashlight that is mainly provided as a portable lighting device is known as a lighting device that uses a battery as a power source. When a power failure occurs, it is very difficult to evacuate from a dark room or find a flashlight.

According to the present invention, when the luminaire is dropped on the floor due to a large vibration or the like in such a disaster, the switch is automatically turned on and the light bulb is turned on to provide an emergency lighting in the room. The purpose is to provide a very interesting lighting fixture in which the evacuation route and direction can be confirmed without any trouble.

[0004]

To achieve the above object, the present invention accommodates a battery 3 in a vertically movable manner in a spherical main body 1 made of a transparent or translucent material having a center of gravity at the bottom and the top. The storage part 2 is installed and the socket part 4 of the light bulb 5 is provided on the upper part of the storage part 2, and the metallic coil spring 6 attached to the lower part of the socket part 4 is brought into contact with the positive electrode of the battery 3 to form the spherical body. 1 is a configuration in which the light bulb 5 is turned on in the normal standing state and is turned off in the inverted state.

[0005]

In the luminaire according to the present invention, a seat plate or the like is installed in the lower part of the storage part 2 to make the center of gravity of the bottom of the storage part 2. The center of gravity of the spherical main body 1 is concentrated on the bottom part by placing the lighting device in a normal standing state in this state, as shown in FIG. Then, the bottom of the battery 3 comes into contact with the current-carrying plate 8 and the switch is turned on, so that the light bulb 5 is turned on. When the lighting fixture is placed upside down, the battery 3 moves toward the light bulb 5 by its own weight, the bottom of the battery 3 is released from the contact with the current-carrying plate 8, and the switch is turned off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below. FIGS. 1 to 3 show the first embodiment, and 1 is a transparent or semi-transparent spherical body of resin or the like. The lower lid 1a and the upper lid 1 are separable from the middle part.
Reference numeral b denotes a screw coupling means at each opening, and a horizontal plane 1c is provided at the bottom and top of the spherical body 1, respectively.
1d is formed. 2 is a storage part of the battery 3, and 4
The main pillars 2a of the book are constructed with an enclosing body, and each main pillar 2a is erected on a metal seat board 7 at the bottom and a mounting plate 10 is installed on the upper part. The socket portion 4 of the light bulb 5 is fixed to the above, and a metallic coil spring 6 is hung below the mounting plate 10, and the coil spring 6 is connected to the positive electrode of the battery 3. Is installed, and the current-carrying plate 8 and any main pillar of the main pillars 2a are connected to each other by an electric wire 9.

FIGS. 4 and 5 show a second embodiment, in which the spherical main body 1 is exactly the same as the first embodiment, but the storage part 2 of the battery 3 is formed by a screw line. A metal coil spring 11 for supporting the bottom of the battery 3 is installed on the bottom, and a mounting plate 12 is provided on the top, and the socket 4 is fixed to the mounting plate 12, and the socket 4 is formed. A coil spring 6 made of metal hung down from is connected to the anode of the battery 3 and a coil spring 11 at the bottom and the socket portion 4 are connected by a conductive wire 13.

[0008]

Thus, the luminaire according to the present invention is placed in an inverted state in which the top is on the lower side when not in use, and in this state the light bulb 5 is in the off state and falls due to a large shaking such as an earthquake. Then, the center of gravity of the spherical body 1 is concentrated in the lower half of the sphere including the battery, so that it is corrected to a normal standing state, and the battery 3 descends in the storage part 2 and the switch is turned on, and the light bulb 5 is automatically turned on. In addition, in the inverted state, the center of gravity is in the upper part, so that the person can easily fall down.

The luminaire of the present invention has the above-mentioned actions and effects, and even if the electric power in the room is instantaneously cut off in the event of a disaster caused by an earthquake, it is possible to obtain the lighting at hand and to evacuate the room. By pre-installing it in a place, it is possible not only to perform evacuation actions quickly, but also to secure the airtightness of the spherical body so that it can float on the water surface and prevent accidents such as marine accidents. It is also useful for searching, and has an advantage that it can be used for many purposes.
