Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guide light lighting device that includes a commercial lighting circuit and a power failure lighting circuit whose power source is a battery that is charged with a commercial power source.

Conventional equipment uses a battery as a power source during a power outage and uses a power outage lighting circuit to turn on the fluorescent lights continuously, and because the fluorescent lights are in a static lighting state, it is difficult for evacuees to recognize the guide light sign board in the event of a disaster. There are drawbacks.

In order to improve this point, as shown in Figure 1, the battery "
It is conceivable to insert a flashing circuit 8' between the power failure lighting circuit 2' and the power failure lighting circuit 2'.

This blinking circuit is composed of a voltageless relay RYo connected to a commercial power supply r and 2m DC relays DR1 and DR2.

Therefore, although the configuration is simple, there is a drawback that the voltageless relay RYo must be connected to a commercial power source r, and it cannot be easily incorporated into a conventional guide light fixture.

The present invention has been devised in view of these points, and one embodiment of the present invention will be described below with reference to FIG. 2.

F is a fluorescent lamp and its filament f1. f2 is connected to the commercial power source E via the commercial lighting circuit 1, and is also connected to the storage battery BK via the power outage lighting circuit 2.

The commercial lighting circuit 1 consists of a normally closed contact NC and a ballast CH of a first relay switch S□ inserted in series between one end of each filament f□, f2 and a commercial power supply E, and a filament f
1. It consists of a glow G inserted between the other ends of f2 and a normally closed contact NC of the second relay switch S2.

S4 is a remote switch. In addition, the power failure lighting circuit 2 is connected to the battery B via the normally closed contact NC of the third relay switch S3.
The inverter circuit 3 connected to the output coil L1 of the oscillation transformer T1 is connected to the filament f via the ballast capacitor C
A circuit 4 connects the first filament preheating coil L to the filament fIVc via the filter capacitor C2, and a circuit 5 connects the second filament preheating coil L3 to the filter capacitor C3 and the first and second relay switch S1. ．． and a circuit 6 connected to the filament f2 via each normally open contact NO of S2.

The first to third relay switches 81 to S3 are controlled by a power failure detection relay coil RYIK, and this relay coil is connected to a commercial power source E via a check switch S5.

I is a charging circuit for storage battery B, which includes a step-down transformer T2 and a diode D1. It is composed of D□ and current reducing resistance R1.

Next, 8 is a blinking circuit according to the present invention, which is inserted between the battery B and the power failure lighting circuit 2 by a pair of connectors CO1 and CO2, and is constructed as follows.

That is, a transformer T3 has a primary coil L4 inserted in the charging/discharging path 9 of the battery B, a transistor Q and a first A series circuit 10 of relay coil RY2, a series circuit 11 of normally open relay switch S6 of first relay coil RY2, and second relay coil RY3
and a normally closed relay switch S7 of the second relay coil RY3 inserted in the charging/discharging path 9, forming a series circuit 10.1.
1 is connected after battery BK via normally closed relay switch S7.

In the above configuration, under normal conditions, the first to third relay switches S□ to S are activated by excitation of the power failure detection relay coil RY□.
3 close their normally closed contacts NC, and the fluorescent pair F is lit by the commercial power source E via the commercial lighting circuit 1.

On the other hand, since the normally closed relay switch S7 is closed, the battery B is being charged from the commercial power source EK via the charging circuit 7.

At this time, the charging current of battery B flowing through charging/discharging path 9 is, for example, 1/30C, and since this charging current is small, the output of transformer T3 is small and transistor Q is in a cutoff state, and relay switches S6 and S7 are In the illustrated state, battery B is being charged.

Next, when a power outage occurs due to the occurrence of a disaster, the first to third relay switches S1 to S3 are switched to their normally open contacts NOK by demagnetizing the power outage detection relay coil RY, and the power outage lighting circuit 2 is closed.

Therefore, the inverter circuit 3 is activated by the discharge from the battery B, and the fluorescent pair F is lit by its high frequency output.

At this time, the discharge current of the battery B is large, for example, □oC, so the induced current in the secondary coil L5 of the transformer T3 is large, and the transistor Q becomes conductive.

Therefore, the normally open relay switch S6 is closed by the excitation of the first relay coil RY2, and the normally closed relay switch S7 is opened by the excitation of the second relay coil RY5.

Therefore, no power is supplied to the inverter circuit 3 (the fluorescent pair F goes out and the induced current in the secondary coil L5).

Since the transistor Q is cut off, the normally open relay switch S6 returns to the open state.

As a result, the second relay coil RY3 is demagnetized, and the normally closed relay switch S7 is also returned to the closed state.

By entering the initial state, power is supplied to the inverter circuit 3 again and the fluorescent pair F lights up again.

Thereafter, the same operation is repeated so that the fluorescent pair F blinks.

Next, FIG. 3 shows another embodiment of the present invention, in which the blinking circuit 8 is constructed by a series circuit 12 of a transformer T3, a silicon controlled rectifier (hereinafter referred to as SCR) SC, and a third relay coil RY4.
and a normally closed relay switch S7.

Its operation depends on the charging current of battery B as described above.
CR(SC) does not ignite (5CR(SC) is ignited only by a large discharge current, and at that time, the normally closed relay switch S7 is opened by the excitation of the third relay coil RY4, and the fluorescent pair F is opened. At the same time, the 5CR (SC) is turned off.

Therefore, the normally closed relay switch S7 is closed due to the demagnetization of the third relay coil RY4, returning to the initial state, and the fluorescent pair F blinks by the same operation thereafter.

As described above, according to the present invention, a blinking circuit is provided in the charging/discharging path of a battery that is charged with a commercial power supply, and the circuit is connected to a transformer in which a primary coil is inserted in the charging/discharging path, and the battery's discharge current is The structure consists of a semiconductor element that is made conductive by the output of the transformer, and a normally closed switch that is opened by the output of the element and inserted into the charging/discharging path, and the element is cut off when the switch is opened. The fluorescent pair can be blinked using a battery, and the dynamic lighting can make the guide light sign board visible to evacuees, improving the function of the guide light.

In addition, since the blinking circuit does not require electrical components that are directly connected to a commercial power source, such as the non-voltage relay coil RYo shown in Figure 1, it can be easily connected to a conventional induction lamp lighting circuit, and can be easily connected to an existing induction lamp lighting circuit. It has great practical effects, such as being able to be easily incorporated into lighting fixtures.
