Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disaster prevention lighting device that can call attention by periodically flashing a light source when an emergency signal such as a fire signal is emitted from the outside.

Conventionally, in disaster prevention lighting devices such as evacuation guide lights and emergency lights,
In the event of a fire, it has been proposed to call attention to the fire by periodically flashing and extinguishing the light source or brightening and darkening it, thereby enabling early evacuation. Such disaster prevention lighting devices are usually as follows. It is made of camphor. That is,
In addition to the well-known disaster prevention lighting and equipment that includes a battery, a charging device for the battery, and a switching device between the regular power source and the battery, a current-limiting impedance that completely limits the supply current to the light source, and an external emergency signal It includes a contact that opens and closes depending on the presence or absence of an emergency signal, and an illumination level control device that is controlled by this contact and periodically inserts and removes the current limiting impedance when an emergency signal is present. Note that the illumination level control device may be one that periodically opens and closes a switch provided in the energizing circuit of the light source. In this case, the light source repeats flashing periodically, and the current limiting impedance is unnecessary. The operation of any type of disaster prevention lighting system both at all times and during a power outage is the same as well-known ones, but when it receives an emergency signal such as a fire signal, the contact is activated, and the lighting level control device is activated accordingly. Therefore, the light source periodically repeats bright and dark or flashes).

However, in such conventional devices, the lighting level is activated during installation work, causing the light source to blink regardless of the occurrence of a non-n state, or causing the light source to flicker, or to cause the light source to flicker, regardless of whether a non-n state occurs or not. ：It is obvious that the problem is repeated.
One. In other words, the emergency signal line is wired separately from the common wire and source wire, but during construction, this wiring may not be completed, or even if it is completed, the current of the specified T may not be passed through it. On the other hand, in this type of device, during a fail-safe period when the signal line is disconnected, when current flows through the signal line and the signal line is in an emergency state, it is assumed that it is an emergency signal. Therefore, during the above-mentioned renovation, the lighting level was set to 11. ``!N device is activated. Therefore, with conventional devices, undesirable blinking or bright/dark cycles occur during the construction period, causing false alarms and annoyance.Also, as a light source, When using fluorescent lamps, there is a risk of shortening the life of the lamp if the flashing or flashing and repeating the bright and dark periods continuously for a long period of time.In order to solve the above problems, it is necessary to control the operation of the lighting level control device. A possible example would be to provide a switch. However, if a manual operation part is provided, which is completely unnecessary except in special cases such as installation work A, it may invite erroneous operation or mischief by the user. It is a possibility.

The present invention was made in order to solve the above-mentioned problem, and it is possible to prevent the light from blinking or blinking undesirably during installation work, etc.
The overall purpose of the present invention is to provide a disaster prevention lighting device which operates stably without causing repeated brightness and darkness, and which prevents erroneous operation or tampering.

The present invention includes a disabling device that detects the connection state of the battery and automatically disables the lighting level control device when the battery is not connected. This may occur during interior construction work, electrical wiring work, etc., where repeated complete prevention is required. ) was made by focusing on the fact that the battery is usually removed. During the construction period, the battery is removed because the t source is completely cut off at night, and as a result, the battery is discharged ′υt t=
It is surmised that this is to prevent any deterioration of battery life due to returning the battery.

According to the present invention, the emergency signal level control device is disabled during the period when the battery is removed, so the emergency signal is equivalently turned on due to incomplete signal wiring during the construction period. Even if the light source is turned on or off, the light source will not turn on or off, or the light source will not return Kr4. This makes it possible to prevent false alarms and annoyance, and it does not require a special manual control section for controlling the lighting level control device.
There is no risk that the original function of this type of disaster prevention lighting system will be impaired due to a single operation or mischief.

In the present invention, the light source may be a light bulb, a fluorescent lamp, or any other light source. Even if it is a light source of the Isuwa type, if you want to make it flash or blink when there is an emergency signal, it is sufficient to supply N2f to the light source intermittently, and if you want to make it bright or dark (dark does not include turning off the light). For this purpose, an impedance element may be used to intermittently limit the current flowing to the light source, or the applied voltage may be intermittently reduced. In addition, when using a fluorescent lamp or other type of q-light, it is necessary to restart it (in the case of flashing) or maintain the lighting (in the case of brightness or darkness), but a person skilled in the art will be able to find a lighting device that meets these requirements. It is well known and can be selected as appropriate. The flashing/blinking or bright/dark period is selected to be an effective value for attracting attention, for example, about 0.5 Hz to several Hz. In addition,
In the case of evacuation guide lights, the period and brightness ratio (in bright/dark cases) should be selected taking into consideration the visibility of the display board.

Further, in the present invention, the disabling device can be configured to detect the voltage between the terminals of the battery connection part to detect the connection state of the battery. In other words, since a charging device for a power supply is generally used to step down the power source voltage, perform full-wave rectification, and then supply the battery to the battery, it depends on whether or not the battery is connected. : Since the voltage between the two terminals is different, it is necessary to check the entire connection state of the battery based on the voltage between the terminals.

However, in the present invention, in addition to the above, it is also possible to use other means such as adjusting the stock depending on the presence or absence of charging current, or completely mechanically detecting the battery connection state. Of course.

Embodiments of the present invention will be described below with full reference to the drawings. (3) is a battery, which is powered by the regular power supply (2) via a well-known charging device (4)k.

The illumination level control device (3) detects the connection state of the lighting level control device (3) and bypasses the output of the oscillator (7) when the battery (3) is disconnected.

It is charged according to the voltage of 1. Therefore, the capacitor (1Ω

On the other hand, when the terminal (3) is disconnected and the contact α is closed, the capacitor (ie) is charged according to the peak value of the non-smooth (1) force of the charging device (4), and in the case described above The voltage between the terminals FE becomes higher.And 1.If the Zener pressure of the Zener diode aυ is selected to be lower than the capacitor (19 and 41 voltage), the transistor (te) will turn on and the oscillator (

) transmits all signals from

Next, we will discuss the effect. If the regular power supply (2) is normal or if the phone is turned on, I will ask you about it. During the equipment construction period, if the wiring of the emergency signal line (20) has not been completed, or even if it has been completed, it is not connected to the fire alarm system,
Contact a of the lighting level control device (6) is closed and the oscillator (power is activated), but since the battery (3) will be removed during the construction period, the disabling device (13) will turn off the oscillator (power). The power output is completely bypassed and the lighting level control device (6) is virtually disabled.The light source (1) therefore does not cycle on and off.With the battery (3) connected ( Since the disabling device 03) does not operate in the case (after completion), the illumination level control device (6) operates in response to an emergency signal from the outside, and causes the light source (1) to blink on and off. When the normal power source (2) is normal, the lighting level control device (6) is not powered by the charging device (4), and when the normal power source (2) is in an emergency, the lighting level control device (6) is powered by the battery (3). It is.

In addition, it will be easily understood that in this embodiment, in order to repeat bright and dark instead of one flash and one flash, it is sufficient to connect all the current limiting impedances in parallel with each of the contacts a0 and ■. . Furthermore, the cycle and time ratio of blinking/blinking or bright/dark can be arbitrarily designed by setting the output of the oscillator (7). Further, it is easily understood that other means such as an oscillator (cutting off the input/output side of the force) may be used as a means for completely disabling the illumination level control device (6).

FIG. 2 shows a second embodiment. The same reference numerals are given to the same sections as in FIG. 1, and corresponding parts are marked with a dash. In this embodiment, the light source (1) is a fluorescent lamp. Therefore, a first ballast (ioo) is inserted in the energizing circuit from the common power supply (2), and a well-known high-frequency converter (1) is inserted in the energizing circuit from the battery (3).
01) and a second ballast (102) are provided. Further, a lighting tube (103) and a noise prevention capacitor (, 104) are provided in parallel with the light source (1). Furthermore, in this embodiment, when there is an emergency signal from the outside, the light source (1)'ft is made to periodically brighten and darken, and the light source (1)'ft is made to periodically brighten and darken, and the light source (1)'ft becomes bright and dark when activated by the common power source (2). At the level, the high frequency converter (101)'e is activated to facilitate re-ignition of the light source (1), so the charging device (4)
)・A separate DC power supply (105) is provided. Next, a power failure detection device i1 in this embodiment is provided at the position shown in the figure. Here, normally open, contact C5-3'
), (5-4) ld opening/closing configuration is reversed when the normal power supply (2) is in an emergency. It is provided at the position of the excitation coil of the illumination level control device (6) in the present Mr1 example. Also, Honji Mj example 2), (12-8)
It is configured to be received by

In particular, the contact (12B) is opened when there is an emergency signal, so it should be installed in series with the noise prevention capacitor, so that if it receives an emergency signal from the outside when it is energized from the regular power supply (2). When the high frequency converter (101) is activated, the noise prevention capacitor (104) prevents the high frequency power from bypassing.

(106) is the first current-limiting impedance provided in parallel with the contact (9-27), and (10,7) is parallel with the series circuit of the contact (5-2) and contact (9-1). This is the second current limiting impedance provided in the .

Next, we will discuss the effect. When an emergency signal is received from the outside while the regular lightning source (2) is energized, it contacts. Therefore, the light source (1) is intermittently supplied with a limited current from the regular power supply (2), while the DC power supply (105) connects the contact (12-1) to the high frequency converter (101) and the A high frequency voltage is applied through the second ballast (102) f. For example, it can be turned on periodically at an illumination level of 100%-36%. At this time, if the battery (3) is not connected, the lighting level control device (
6) is disabled in the same way as in the case of FIG. If there is an emergency signal when energized from the battery (3),
By inserting and removing the second current limiting impedance (107), it is possible to turn on the light at an illumination level of, for example, 36%-10%. Are other effects similar to those in Figure 1?
Since it is easily understood, the explanation will be omitted.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but may be modified in various ways. For example, when the light source is energized by a battery, it is possible to prevent the illumination level of the light from changing even if there is an emergency signal from the outside. In this case, it is possible to eliminate the distraction caused by the lighting level control device,
You can make your battery last longer. In addition to the fire signal, the emergency signal may be a signal from a μ/J crime device or the like. Furthermore, the specific configurations of the illumination level control device and the disabling device can be modified in various ways other than those described in the second embodiment, which can be easily accomplished by those skilled in the art. Furthermore, it's a half-W body switch as various contacts? It may also be used without contact.

As described in detail above, the present invention is based on the fact that the battery is removed during equipment construction and the like.

When the battery is not connected, the lighting level is automatically set to 1j! Since the control device is placed in the lower section, the light source may undesirably flash or blink or become bright or dark even when there is an emergency signal from the outside, such as during demolition work. The system is powerful and can prevent false alarms and annoyance, and since it is not equipped with an operating section for manual operation, there is no need to worry about making it more attractive in an emergency due to erroneous operation or mischief. 3. It is possible to provide a disaster prevention lighting system that does not pose a risk of impairing the functions of
