Description

[Detailed explanation of the invention] This invention uses a lighting switch to turn on a lamp such as a fluorescent lamp while the commercial power supply is on, and to constantly charge a secondary battery.When the commercial power supply is out of power, the secondary battery is used as a power source. This invention relates to an emergency lighting device that lights up an emergency light body.

Conventionally, this kind of emergency lighting equipment uses commercial 100V as a power source, and normally the fluorescent tube is turned on and off by a lighting switch and charged to a secondary battery.In the event of a power outage, this secondary battery is used as a power source, and an inverter is used to turn the fluorescent tube on and off. Some lights use the fluorescent tube as an emergency light. On the other hand, in buildings, commercial 200V
There are places where power is supplied to the indoor wiring, and in order to install emergency lighting equipment using the commercial 100V power supply in such places, conventionally it was used for charging the secondary battery and when the commercial power supply is energized. For lighting the lamp body,
Separate down transformers were prepared for each, and the 100V power obtained from these down transformers was used to feed each. Furthermore, by connecting the commercial 200V power supply to other lighting equipment through the lighting switch of this emergency lighting equipment, you can
When the 200V power supply is turned on, the light body of the emergency lighting equipment and the other lighting equipment can be turned on and off at the same time by opening and closing the lighting switch.

However, according to this conventional example, two large down transformers are built into the conventional emergency lighting equipment for commercial 100V power supply, which makes the installation space narrow and the installation work complicated. Furthermore, since two expensive down transformers are used, the manufacturing cost increases significantly.

This proposal was developed in consideration of the above points, so that power is generated in parallel between one power terminal and the intermediate terminal of one down transformer, and between this intermediate terminal and the other power terminal.
The 100V power supply is used for charging and for lighting the lamp when the commercial power supply is energized, and
Commercially available via a light switch that lights this light body.
Even when power is supplied to other lamps from the 200V power supply, the lamp body is prevented from faintly illuminating or lighting up due to the circulating current from the other lamps when the lighting switch is in the open state.

The emergency lighting equipment of the present invention will be explained below based on the circuit diagram of the embodiment. 1 is an emergency lighting circuit that operates on a commercial 100V power supply, and a charging circuit 3 that charges a secondary battery 2 with the 100V power supply and its pair of inputs.

The fluorescent tube 5 is turned on by a switch (not shown) inserted in the 100V power supply.Furthermore, in the event of a power outage of 100V, the power failure detection relay 11 switches from the normal lighting circuit 9 to the emergency lighting circuit 6, and the fluorescent tube 5 is turned on.

14 is a down transformer that converts a commercial 200V power supply into a 100V power supply, and has a pair of power supply terminals 15, 15' and an intermediate terminal 16. If AC 200V is applied to this pair of power supply terminals 15, 15', An output of 100 V AC is generated between the intermediate terminal 16 and one power terminal 15 or the other power terminal 15'.

The relay is connected to the connection point between the power supply terminal 15' and the second terminal 18, and the other end is connected to the first terminal 17, and the other end of the coil is connected to the normally open contact 22 of this relay 21 to It is connected to the other input terminal 10 of the lighting circuit 9.

Reference numerals 23 and 23' denote a pair of expansion output terminals connected to the first terminal 17 and the second terminal 18, respectively.

Another lamp 26 that can be turned on and off is also connected thereto.

When the commercial 200V power supply is energized, 100V power is provided to the charging circuit 3 from the intermediate terminal 16 of the down transformer 14 and one power supply terminal 15, and the relay 21 is energized by the closing operation of the lighting switch 25, and the intermediate terminal 15 of the down transformer 14 is turned on. The fluorescent tube 5 is lit with the 100V power generated between the terminal 16 and the other power supply terminal 15', and at the same time, the other lamps 26 are lit with the commercial 200V power, while the relay 21 is turned on by opening the lighting switch 25. The power is turned off and the connection between the input terminal 10' of the normal lighting circuit 9 and the first terminal 17 is opened, and the power supply to the other lamp 26 is also stopped, and the current from the other lamp 26 to the fluorescent tube 5 is stopped. This also completely blocks the intrusion of the fluorescent tube 5 and the other lamps 26. Furthermore, in the event of a power outage of the commercial 200V power supply, both this relay 21 and the power outage detection relay 11 are de-energized, and therefore, the secondary battery 2 is used as a power source to drive the emergency lighting circuit 6, and the fluorescent tube 5 is turned on in an emergency manner. It's summery.

a relay connected between two power supply terminals via a lighting switch, and the one power supply terminal and the intermediate terminal are connected to the pair of input terminals of the charging circuit, and the relay is connected from the connection point between the lighting switch and the relay. Since the relay is connected to one input terminal of the normal lighting circuit through the normally open contact, and the intermediate terminal is connected to the other input terminal of the normal lighting circuit, the 100V power supply is connected in an emergency. In order to drive a lamp with a commercial 200V power supply, only one down transformer is required compared to the conventional two, thus significantly reducing manufacturing costs. In addition, there is only one down transformer to be built into the emergency lighting equipment, and a relay that is considerably smaller than the down transformer can be installed, so there is more space for installation, simplifying the installation work, and allowing the lighting switch to turn on both devices at the same time.・Even if you add other light fixtures that are turned off, no current will flow from the other light fixtures to the light body when the light switch is open, so even if the light switch is open, no current will flow into the light body. It is possible to obtain an emergency lighting device in which there is no fear that the lamp body will dimly light or turn on.
