[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a portable lighting device PT according to an embodiment of the present invention.

In FIG. 1, an AC power supply 1 output from a power supply facility is supplied to electric equipment via a receptacle 2, and a power outlet 3 of the portable lighting device PT is connected to the receptacle 2.

The power outlet 3 is fixed to the outside of a casing (not shown) of the portable lighting device PT. For this reason, when the power outlet 3 is connected to the receptacle 2, the portable lighting device PT Is fixed to a wall or the like to which the receptacle 2 is attached.

An AC power supply 1 supplied via a power outlet 3 is applied to a rectifier 4. The rectifier 4 converts the applied AC power supply 1 into a DC power supply having a predetermined voltage. The output of the rectifier 4 is connected to the DC relay 5, the input terminal of the charger 6, and one of the relay contacts 5 a of the DC relay 5. It is connected to the normally open contact 5aa.

The charger 6 supplies the applied DC power to the battery 8 via a backflow preventing diode 7 to charge the battery 8, and the output of the battery 8 is supplied to a relay contact. 5a is added to the normally closed contact 5ab.

The common contact 5ac of the relay contact 5a is connected to an input terminal of the blinking circuit 9, one connection terminal of a manual switch 10 for turning on / off a detour of the blinking circuit 9, and a relay that is turned on / off in conjunction with the relay contact 5a. The contact 5b is connected to the normally open contact 5ba.

The blinking circuit 9 turns on and off the input DC power supply at a predetermined duty, and its output terminal is connected to the normally closed contact 5bb of the relay contact 5b.

The common contact 5bc of the relay contact 5b is connected to one input terminal of the lamp 11.

In the above configuration, when the power outlet 3 of the portable lighting device PT is connected to the receptacle 2 and the portable lighting device PT is fixed, AC power is supplied to the rectifier 4. The DC power is output, whereby the battery 6 is charged by the charger 6, the DC relay 5 is turned on, and the relay contacts 5a and 5b are switched to the normally open contacts 5aa and 5ba, respectively.

Thus, the DC power output from the rectifier 4 is supplied to the lamp 11 via the normally open contact 5aa of the relay contact 5a, the common contact 5ac, the normally open contact 5ba of the relay contact 5b, and the common contact 5bc. As a result, the lamp 11 is continuously turned on.

On the other hand, when the power supply equipment stops for some reason and the supply of the AC power supply 1 is cut off, or when the power outlet 3 of the portable lighting device PT is removed from the receptacle 2, Since the supply of the AC power supply 1 is cut off, no DC power is output from the rectifier 4.

As a result, the charging operation of the charger 6 for the battery 7 is stopped, the DC relay 5 is turned off, and the relay contacts 5a and 5b are switched to the normally closed contacts 5ab and 5bb, respectively.

As a result, the DC power output from the battery 7 is applied to the blinking circuit 9 via the normally closed contact 5ab of the relay contact 5a and the common contact 5ac, and the output of the blinking circuit 9 is applied to the relay contact 5b Is supplied to the lamp 11 via the normally closed contact 5bb and the common contact 5bc.

At this time, when the manual switch 10 is not turned on, the output of the blinking circuit 9 is valid, and the lamp 11 blinks and lights.

In this state, when the user of the portable lighting device PT turns on the manual switch 10, the DC power output from the battery 7 is changed to the normally closed contact 5ab of the relay contact 5a, the common contact 5ac, Since the power is supplied to the lamp 11 via the manual switch 10, the normally closed contact 5bb of the relay contact 5b, and the common contact 5bc, the lamp 11 is continuously turned on.

As described above, in the present embodiment, when the portable lighting device PT is used as a guide light or an emergency light in a ship, it is continuously lit when the power outlet 3 is connected to the receptacle 2 of the AC power supply 1. However, when the AC power supply 1 is cut off for some reason, it flashes and lights up, so that the lighting time that can be turned on during a power failure can be greatly increased, which is very convenient.

Further, when the manual switch 10 is turned on, the lighting is switched to continuous lighting, so that a lighting mode desired by the user can be easily selected, and the availability of the present apparatus is expanded.

Here, when a switch that performs a toggle operation is used as the manual switch 10, the usability of the user is further improved. Further, the blinking operation of the blinking circuit 9 may be turned on / off by the manual switch 10.

FIG. 2 shows a portable lighting device PTa according to another embodiment of the present invention. In this figure, the same parts as those in FIG. 1 and corresponding parts are denoted by the same reference numerals.

In FIG. 1, an AC power supply 1 output from a power supply facility is supplied to electric equipment via a receptacle 2, and a power outlet 3 of a portable lighting device PTa is connected to the receptacle 2.

The power outlet 3 is fixed to the outside of a housing (not shown) of the portable lighting device PT. For this reason, when the power outlet 3 is connected to the receptacle 2, the portable lighting device PTa Is fixed to a wall or the like to which the receptacle 2 is attached.

The AC power 1 supplied via the power outlet 3 is applied to an AC relay 15.

The dry battery 16 is a DC power supply for lighting the lamp 11, and the output of the dry battery 16 is applied to a normally closed contact 15 ab of a relay contact 15 a of the AC relay 15.

The common contact 15ac of the relay contact 15a is connected to an input terminal of the blinking circuit 9 and one connection terminal of a manual switch 10 for turning on and off a bypass of the blinking circuit 9, respectively. The normally open contact 15aa of the relay contact 15a is open.

The blinking circuit 9 turns on and off the input DC power at a predetermined duty, and has an output terminal connected to one input terminal of the lamp 11.

With the above configuration, when the power outlet 3 of the portable lighting device PTa is connected to the receptacle 2 and the portable lighting device PT is fixed, AC power is supplied to the AC relay 15. 15 is turned on, and the relay contact 15a is switched to the normally open contact 5aa.

As a result, the DC power of the dry battery 16 is not applied to the lamp 11, so that the lamp 11 is turned off. That is, in the present embodiment, while the portable lighting device PTa is fixed to the wall, the lamp 11 of the portable lighting device PTa does not turn on.

On the other hand, when the power supply equipment is stopped for some reason and the supply of the AC power supply 1 is cut off, or when the power outlet 3 of the portable lighting device PTa is removed from the receptacle 2, the AC relay 15 Since the supply of the AC power supply 1 is cut off, the AC relay 15 is turned off, and the relay contact 15a is switched to the normally closed contact 5ab.

As a result, the DC power of the dry battery 16 is applied to the blinking circuit 9 via the normally closed contact 15ab of the relay contact 15a and the 1 common contact 5ac, and the output of the blinking circuit 9 is supplied to the lamp 11. You.

At this time, when the manual switch 10 is not turned on, the output of the blinking circuit 9 is enabled, and the lamp 11 blinks and lights.

When the user of the portable lighting device PTa turns on the manual switch 10 in this state, the DC power of the dry battery 16 is changed to the normally closed contact 5ab of the relay contact 5a, the common contact 5ac, and the manual switch. Since the lamp 11 is supplied to the lamp 11 via the lamp 10, the lamp 11 is continuously turned on.

As described above, in this embodiment, when the portable lighting device PTa is used as an emergency light in a ship, the light is turned off when the power outlet 3 is connected to the receptacle 2 of the AC power supply 1, and the AC power is turned off. When the power supply 1 is cut off for some reason, it blinks and lights up, so that the lighting time that can be turned on in the event of a power failure can be greatly increased, which is very convenient.

When the manual switch 10 is turned on, the lighting mode is switched to continuous lighting, so that the lighting mode desired by the user can be easily selected, and the availability of the present apparatus is expanded.
