One terminal is connected to a rectifier such as a selenium rectifier or a silicon rectifier and a resistor R2 for setting the current value to prevent the battery from being overcharged.

The other terminal on the secondary side of the transformer T is connected to the negative terminal of the battery BT, and the B contact RY of the AC relay RY is connected to the negative terminal of the battery BT.
-bl is connected in parallel to the lighting switch SW2, and the batch! Connectors J1 to J3 are interposed in the electrical circuit connecting J-BT and lighting switch SW2, resistor R2, transformer T, and B contact RY-bo of the AC relay to make them detachable. Electrical components other than the portable lighting device 1 are housed in a main body 2, which is attached to a wall 3 of a building with wood screws or screws 4.

Next, the operation of the emergency lighting device of the first embodiment will be explained.

Connect the input terminal to an AC power source (for example, 100
■), the voltage generated on the secondary side of the transformer T is rectified by the rectifier and becomes direct current, and the voltage generated on the secondary side of the transformer T is
2 causes a voltage drop and a safe value of current is applied to batch IJ-B.
Since the current flows to T, the battery BT is always in a charging state.

At this time, when the self-holding switch SW□ is pressed to turn it on, the input current flows through the always-on type mercury seismic switch Hg-8, the coil button of the AC relay RY, and the circuit of the switch SW1, so the AC relay RY is energized and its human contact RY al is turned on.

Therefore, even if the switch SW1 is turned off after that, the mercury seismic switch Hg-8, the coil of the AC relay RY, and its A contact RY a10 circuit are configured.
The AC relay RY becomes self-holding and therefore current continues to flow through the circuit.

When the AC relay RY in the housing is energized, its B contact R
Since Y-bl is turned off, the illumination device is turned off.

This is the set state, that is, the shock sensing standby state.

Next, due to the seismic force with an intensity above a certain value, the mercury grains in the mercury seismic switch H, 9-8 move relative to the container due to inertia, and the mercury seismic switch Hg-8 is turned off. Then, the circuit including the coil of the AC relay RY is momentarily turned off and the self-holding is released, so the A contact RYa1 is turned off, so that the mercury seismic switch H,? -8 is restored to on, the AC relay RY is not dynamically energized.

When the self-holding state is released, the B contact RY-b is turned on, so that current flows through the illuminator and lights it up.

In addition, in the case of a power outage, no current flows through the circuit including the coil of the AC relay RY, so the self-holding is released as in the case of earthquake detection, and the lighting device is turned on by the discharge current of the batch IJ-BT. Ru.

Furthermore, the portable lighting device 1 is separated from the main body 2 at the connectors J1 to J3 and carried, and the lighting switch SW2 is connected to the case.
The lighting device may be turned on or off by performing on/off control.

In this embodiment, one AC relay can be used to sense both earthquakes and power outages.

FIG. 5 shows a second embodiment of this invention, in which the primary side of a transformer T1 is connected to an oscillation circuit 6 equipped with a low frequency power transistor Tr, and the secondary side of the transformer T1 is A fluorescent lamp L1 is connected to the lamp L1 to form a fluorescent lamp type illuminator, but the other configurations and functions are the same as in the first embodiment.

In Fig. 5, C1 and C2 are capacitors, R
1-R4 is a resistor.

When implementing this invention, as shown in FIG.
As shown in the figure, a light emitting diode LED button for power display and a current adjustment resistor R6 may be connected in series on the DC output side.

As shown in FIG. 8, control terminals 7 are provided at both ends of the illuminator made of incandescent lamps in the first embodiment, or control terminals 7 are provided at both ends of the illuminator made of incandescent lamps in the first embodiment, or control terminals 7 are provided at the DC input power source of the fluorescent lamp type illuminator in the second embodiment. A terminal 7 may be provided, and an alarm buzzer or radio may be connected to the control terminal 7 to make it sound.

As shown in FIG. 9, a control terminal 7 is provided to the DC power supply on the secondary side of the transformer T via the A contact RYa2 of the AC relay RY, and the control terminal 7 is connected to an electrical mechanical appliance that is always operated. If connected, when the always-on type mercury seismic switch Hg-8 is turned off due to an earthquake, the A contact RY a2 of the AC relay RY will be turned off, so that the electric mechanical appliances Operation can be stopped automatically.

In addition, as shown in Fig. 10, the A contact R of the AC relay RY
If you take out terminal 7 from Ya2 and B contact RY-b 2 and press the button, you can arbitrarily select the voltage-free A contact button and B contact, so you can operate any electrical equipment at any voltage regardless of the output voltage. Can be controlled on and off.

Furthermore, when adding various control terminals, use AC relay R.
It is sufficient to use a Y contact structure having two circuits, two ab contacts or more, as shown in FIG.

FIG. 12 shows an example of an always-on type mercury seismic switch. Pressing is performed using a mold having a surface to form a rough surface 10 consisting of a large number of fine irregularities with protrusion intervals of 1 to 100 microns, and mercury 11 is placed in the center of the rough surface 10. Furthermore, a lid 13 made of a conductive metal material is brought into contact with a flange 12 provided at the periphery of the upper opening of the container main body 8 and fixed by welding, and the lid 13 and the container main body 8 form a hermetic seal. A container 14 is constructed.

Mounting holes 15 for inserting mounting rivets or screws are provided on both sides of the lid 13, and a through hole 16 provided at the center of the lid 13 is filled with an electrically insulating material such as glass or synthetic resin. A sleeve 17 consisting of the above is fitted and fixed with an adhesive, and an electrode 18 is fitted into the sleeve 17 and fixed with an adhesive.

The lower end of the electrode 18 is placed on the central extension of the concave spherical bottom plate 9 and inserted into the upper center of the mercury 11 .

One electrical wiring is connected to the electrode 18, and the other electrical wiring is connected directly to the lid 13 or to a conductive metal support member fixed to the lid 13.

In the state shown in FIG. 12, the mercury 11 is in contact with the conductive material container body 8 and the lower end of the electrode 18 is inserted into the mercury 11, so the electric shock switch remains on.

From this state, when the seismic switch container 14 is shaken horizontally due to an earthquake force or other large vibration force, the mercury 11 moves relatively toward the side of the container 14 due to its own static inertia. Since the seismic switch moves away from the electrode 3, the seismic switch is turned off.

According to this invention, by simply turning on the self-holding switch SW1 temporarily, the AC relay RY can be excited and self-maintained to be in an earthquake detection standby state. When the always-on type mercury-type seismic switch H9-8 is turned off by force, the B contact RY-b 1 for lighting circuit control, which switches on the self-maintained AC relay RY, is turned on, so the lighting equipment The connector J
The portable lighting device 1 can be separated from the main body 2 at the portion ˜J3 and illuminated while being carried.
