[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor guide light device capable of safely guiding local residents to evacuate even if a wide area power failure occurs in the event of a disaster such as an earthquake.

[0002]

2. Description of the Related Art For large-scale buildings, it is obligatory to install an emergency lighting device according to the Building Standards Act and a guide light device according to the Fire Service Act.

In the case of an emergency or the like, these appliances have a fixed time or more so that people in the building can safely evacuate to the outside even if the commercial power source is cut off.
It can be lit with a specified illuminance. That is, these devices have a built-in battery called a secondary battery inside the equipment, which is normally charged by a commercial power source, and when the commercial power source fails in an emergency, the battery is used as a power source and a lamp. Is turned on automatically.

[0004]

In the case of such a conventional technique, the lamp is designed to be lit simply on the condition of a power failure of the commercial power source. Therefore, if the lamp is installed outdoors, the power failure will occur even in the daytime. There is an unavoidable problem that the lamp is turned on each time and not only the battery and the lamp are wastefully consumed but also energy is wasted.

Therefore, in view of the problems of the prior art, the object of the present invention is to turn on the lamp only when a power failure occurs at night, so that there is no inconvenience even when it is installed outdoors. An object is to provide an outdoor guide light device that does not include the above.

[0006]

The structure of the present invention for achieving the above object includes a lamp, a battery for always trickle charging, and a switching circuit for lighting the lamp by the battery when commercial power is lost at night. It is the gist to provide. However, the battery can always be trickle charged by a commercial power source, a solar cell, or the like.

Embodiments Embodiments will be described below with reference to the drawings.

The outdoor guide light device includes a lamp L and a battery B.
And become the main members (Fig. 1).

The battery B is always trickle charged by the commercial power supply AC. That is, the commercial power supply AC is connected to the primary side of the transformer T via the normally closed contact of the inspection switch SW, and the secondary side of the transformer T is connected to the battery via the rectifier RF, the resistor R1, and the fuse F. B is connected. A relay RY is connected in parallel to the primary side of the transformer T, while a resistor R1
A series circuit of a resistor R2 and a light emitting diode LD is connected in parallel. A blinker RT is connected to the output side of the rectifier RF via another normally-closed contact of the check switch SW.

The lamp L is a normally closed contact RYb of the relay RY.
And a normally closed contact RTb of the blinker RT are connected in series, and are branched and connected to the output side of the resistor R1.

Now, when the commercial power supply AC is normal, the resistor R1 compensates for the self-discharge of the battery B, and moreover, the charging current for the battery B is optimally regulated so that the battery B is not overcharged. If so, the battery B can always be trickle charged by the commercial power supply AC as long as the commercial power supply AC is normal.
Further, at this time, the light emitting diode LD detects the voltage generated across the resistor R1 through the resistor R2 and emits light,
It can be operated as a charging display for displaying the charging operation of the battery B.

On the other hand, the blinker RT is operated by detecting the presence of sunlight by a light receiving sensor (not shown). That is, the blinker RT operates so as to close the normally closed contact RTb when the surroundings are dark at night and open the normally closed contact RTb during the daytime. Further, the blinker RT closes the normally closed contact RTb when the power supplied thereto is lost.

Therefore, when the commercial power supply AC is normal, the relay RY operates and the normally-closed contact RYb is open, so that the lamp L does not light regardless of the operation of the blinker RT. .. Also, if the commercial power supply AC is lost,
Since the relay RY returns and the normally closed contact RYb closes, the lamp L can blink according to the operation of the blinker RT. That is, the switching circuit 11 can detect that the blinker RT is at night and can turn on the lamp L on condition that the commercial power supply AC is lost when the normally closed contact RTb is closed.

As the battery B, for example, Ni-
When using a Cd battery (DC6V, capacity 4000 mAh), the lamp L can realize a continuous lighting time of about 1.7 hours by using an emergency halogen lamp of about 10 W.

When the inspection switch SW is pushed, the normally-closed contact is opened, so that the circuit connecting the commercial power source AC and the primary side of the transformer T is cut off, and the relay RY is restored. At the same time, the power to the blinker RT is cut off by opening another normally closed contact of the inspection switch SW.
The normally closed contacts RYb and RTb forming the switching circuit 11 are both closed, and the switching circuit 11 switches the lamp L to the battery B.
Can be connected to. That is, the inspection switch SW
By operating, the lighting condition of the lamp L can be forcibly given to the switching circuit 11, and the lamp L is turned on by the battery B and its operation can be checked.

In the above description, the outdoor guide light device is
It shall be installed in a suitable outdoor case and shall be installed together with, for example, streetlight poles, electric poles, etc. installed along the road. Further, at this time, the inspection switch SW may be operated from the ground by an appropriate operation rod or the like for convenience of operation.

If a solar cell is connected to the output side of the rectifier RF via a diode for preventing backflow, the battery B can be always trickle charged by the solar cell during the daytime. When the commercial power supply AC is normal, the consumption of the commercial power supply AC can be suppressed to a necessary minimum. The solar cell at this time may be replaced with any other power generation element.

[0024]

[Other Embodiments] The switching circuit 11 is formed by the switching contact RYc of the relay RY and the normally closed contact RTb of the blinker RT, and can be inserted in the low potential side of the lamp L (FIG. 2). However, the normally open contact side of the switching contact RYc is connected to the output side of the light emitting diode LD.

When the commercial power source AC is normal, the relay RY is operating and the switching contact RYc connects the light emitting diode LD and the lamp L. Therefore, the light emitting diode LD at this time is the lamp L. The voltage across the resistor R1 is detected via the resistor R1, and the fact that the filament of the lamp L is normal, that is, the normal indication of the lamp L can be used together with the charge indication of the battery B.
In the switching circuit 11, when the commercial power supply AC is lost at night or when the inspection switch SW is pushed, the switching contact RYc returns to the normally closed contact side and the normally closed contact RTb closes. As a result, the lamp L can be connected to the battery B and the lamp L can be turned on.

Further, the battery B includes a light emitting diode L.
A voltage monitoring circuit 12 with D1 can be attached (FIG. 3).

The lamp L is connected to the commercial power source AC via the check switch SW, the charging circuit 13, and the switching circuit 11, and the battery B is connected to the switching circuit 11. The output side of the inspection switch SW has a power failure detection circuit 14
The output of the power failure detection circuit 14 is connected to the blinker R
T is connected to the timer 15. The other output of the power failure detection circuit 14 is connected to the switching circuit 11 together with the output of the blinker RT.

The output of the timer 15 is connected to another timer 16, and the outputs of the timers 15 and 16 are branched and connected to the power failure detection circuit 14 and the blinker RT. The output of the timer 16 is also connected to the voltage monitoring circuit 12.

Now, the switching circuit 11 is the power failure detection circuit 1
4. Due to the output of the blinker RT, when the commercial power supply AC is lost at night, the lamp L is connected to the battery B, and at other times, the battery B is connected to the charging circuit 13. Is the charging circuit 1 as in the previous embodiment.
Via Trickle Charge with commercial power supply AC through 3,
The lamp L can be turned on by the battery B according to a predetermined condition. The same applies when the inspection switch SW is pressed and operated. When the inspection switch SW is operated, the power failure detection circuit 14 operates, and the power failure detection circuit 14 causes the blinker RT to operate in the same manner as when the blinker RT detects night, and also causes the switching circuit 11 to operate with the commercial power source. This is because the fact that AC has been lost can be transmitted.

On the other hand, when the inspection switch SW is pushed for a predetermined time or longer, the timer 15 operates and the checking operation of the battery B can be started.

When the timer 15 detects that the inspection switch SW has been continuously pressed for more than the set time, it sends a signal to the power failure detection circuit 14 and the blinker RT to lock its operation. That is, the power failure detection circuit 14 and the blinker RT at this time retain the state when the inspection switch SW is pressed even if the inspection switch SW is restored, and therefore the lamp L is lit by the battery B. You can continue. The timer 15 is set to a set time of several seconds, for example.

The timer 16 is started by the timer 15. That is, the timer 16 measures the elapsed time length until the check operation of the battery B is completed, and after the set time elapses, the state hold of the power failure detection circuit 14 and the blinker RT is released. The timer 16 is turned off when the time is up. At this time, the timer 16
The voltage monitoring circuit 12 is operated, the voltage monitoring circuit 12 measures the output voltage Vb of the battery B at that time, and Vb ≧ V
The light emitting diode LD1 can be turned on at the time of o (however, Vo is a predetermined voltage set in advance). Therefore, the voltage monitoring circuit 12 can turn on the lamp L for a predetermined time defined by the timer 16, check the output voltage Vb of the battery B at that time, and display the result by the light emitting diode LD1.

The setting time of the timer 16 is preferably set to about several tens of minutes in consideration of the continuous lighting possible time of the lamp L determined by the capacity of the battery B.

It is assumed that the light emitting diode LD1 is turned off by a worker pressing a reset switch (not shown) after the set time of the timer 16 has elapsed. Therefore, when checking the battery B in many devices, the worker turns on the lamp L sequentially through the inspection switch SW and the timer 15, and after the elapse of the set time of the timer 16, the worker turns on the light emitting diode LD1. The light emission state may be sequentially checked. After the elapse of the set time of the timer 16, the switching circuit 11 automatically returns to the initial state in which the lamp L is turned off and the battery B is trickle charged.

In the embodiment of FIG. 3, the switching circuit 11 may be provided with an infrared sensor or the like (hereinafter referred to as a human sensor) for detecting the human body. If the switching circuit 11 at this time is at night and the commercial power supply AC is normal, the switching circuit 11 is activated when the human sensor detects the human body, and the lamp L is lit by the commercial power supply AC. The lamp L lights up at night only when there is a passerby, and can be used for the convenience of the passerby. It should be noted that the lamp L at this time may be automatically turned off after a lapse of time of about several minutes after lighting. This is because it is not necessary to turn on the lamp L after a passerby passes by.

[0036]

As described above, according to the present invention, by combining the lamp, the battery, and the switching circuit for lighting the lamp by the battery when the commercial power source is lost at night, the lamp can be operated at night. In, at the time of a power failure due to a disaster such as an earthquake, it can be automatically turned on, and there is no useless lighting operation during the daytime, so there is no danger of wasting the lamp or battery. In the event of a disaster, there is an excellent effect that local residents can be properly guided and evacuated to a safe evacuation site.
