Japanese Patent Laid-Open No. 11-25371

  In the prior art described in Patent Document 1, the power source from the battery has to be boosted to a very high voltage in order to turn on the xenon lamp which is a light source for blinking lighting. Therefore, since the xenon lamp that becomes high pressure cannot be exposed and disposed, the xenon lamp is provided so as to be accommodated in the housing.

  In such a conventional technique, since the xenon lamp is housed and arranged in the housing, it may be difficult for the xenon lamp itself to generate initial electrons for enabling the start of discharge, resulting in poor darkness characteristics. There was a problem that there is a risk of becoming.

  In other words, the xenon lamp, which is a discharge lamp, starts immediately because the initial electrons are generated in the tube by ambient light in a bright place, but starts in a dark place or in a dark place such as in a housing. Since it takes a long time, it may not be possible to light up immediately in an emergency, and it may be difficult to ensure safety quickly.

  The present invention has been made in view of the above, and a flashing emergency lighting device capable of quickly flashing a light source and notifying an evacuee of an evacuation direction in an emergency, regardless of surrounding conditions and light source arrangement conditions. The purpose is to provide.

According to the flashing emergency lighting device according to claim 1, the battery; the LED; the charging circuit for charging the battery at all times; and the switching means for switching so that the power from the battery is supplied to the LED in an emergency. A boosting means for boosting the power supply from the battery higher than the battery voltage value in an emergency, and outputting the boosted power supply to the LED to turn on the LED; a receiving section for receiving an external signal; and a receiving section receiving LED lighting starts according to the received signal, and blinking control is started. When the receiving unit receives the signal again after the blinking control is started, the LED blinking control state is changed according to the signal received by the receiving unit. and lighting control means for;
It is characterized by comprising.

  The flashing emergency lighting device according to claim 2 is characterized in that, in the flashing lighting device according to claim 1, the step-up ratio by the boosting means is lower than that in the case where the lighting of the xenon lamp is controlled to flash.

  In the present invention and the following inventions, definitions and technical meanings of terms are as follows unless otherwise specified.

  The switching means may be either a mechanical contact or an electrical contact. Moreover, what can be switched intentionally by external operation may be used.

  The boosting means is a concept including a lighting circuit for lighting the LED, but the boosting part and other circuit parts are appropriately configured and are not particularly limited.

  Further, it is preferable that the boosting range of the boosting means is a boosting range in which the LEDs can be exposed and arranged. Thereby, since LED can be exposed and arrange | positioned outside, it becomes easy to visually recognize the light irradiated from LED from a distance, and the freedom degree of design can be expanded.

  It should be noted that the boost range is not strictly interpreted, and includes a range that slightly fluctuates as long as the effect of the present invention is achieved.

  The blinking control means is preferably one that turns on the LED with a pulse width, but is not particularly limited as long as it controls the LED to blink apparently.

  The operation of the present invention will be described. For example, when a fire signal is input from an external signal device, the switching unit switches so that power from the battery is supplied to the boosting unit. The boosting unit boosts the power supply of the battery to a value greater than the battery voltage value, supplies the boosted power to the blinking control unit and the LED, and the LED blinks and lights by the on / off control of the blinking control unit.

The flashing emergency lighting device according to claim 3 is the flashing lighting device according to claim 1 or 2, further comprising: a fixture main body provided with a charging circuit, a switching unit, and a flashing control unit; Is arranged so as to be exposed to the outside of the instrument body .

  Since the output voltage of the LED is low, the LED may be disposed so as to be exposed to the outside. In addition, when the LED is exposed to the outside, the visibility does not deteriorate even if the LED is not relatively high in brightness. Therefore, the battery charging voltage can be reduced by using an LED that does not have high energy consumption efficiency. The decrease rate of the battery can be suppressed, and the flashing lighting for a long time can be maintained, or the battery can be miniaturized.

  According to the first and second aspects of the present invention, since the LED can be used as the flashing light source, even in a dark environment, the LED can quickly flash to notify the refugee of the evacuation direction in an emergency, which is highly safe. The flashing emergency lighting device with high reliability and high reliability can be provided.

Block diagram showing the flashing emergency lighting device of the present embodiment

  An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a flashing emergency lighting device according to an embodiment of the present invention.

  The signal device 1 is disposed in one place of the entire system, for example, and the flashing emergency lighting device 10 is disposed at a plurality of positions where evacuation guidance is required such as an evacuation passage and an evacuation stairs. The signal device 1 is notified of the occurrence of an emergency such as a fire from fire detectors (not shown) disposed at a plurality of appropriate locations.

  When the signal device 1 determines that an emergency has occurred due to the notification from the fire detector or the like, the signal device 1 grasps the evacuation passage and evacuation stairs to be evacuated from the information based on the notification, and in the vicinity of these positions. A control signal indicating that an emergency has occurred in the flashing emergency lighting device 10 is provided.

  The flashing emergency lighting device 10 includes a charging circuit 2, a switching circuit 3, a battery 4, a booster circuit 5, a flashing control unit 8, and an LED light source unit 7. The flashing emergency lighting device 1 is connected to a regular power supply 9 that constantly generates a power supply voltage, and the power supply voltage from the regular power supply 9 is supplied to the charging circuit 2 at all times.

  The charging circuit 2 is connected to the battery 4 via the switching circuit 3. The switching circuit 3 supplies the charging current from the charging circuit 2 to the battery 4 at all times, and when the emergency signal is notified by the control signal from the signal device 1, the switching circuit 3 sends the battery 4 to the booster circuit 5. It comes to connect. Thereby, the battery 4 is normally charged, and when an emergency occurs, the charging voltage of the battery 4 is supplied to the booster circuit 5. The switching circuit 3 is provided with a control circuit (not shown). This control circuit has a receiving unit for receiving a control signal from the signal device 1, and can control a blinking control circuit 6 to be described later by identifying the input signal.

  The booster circuit 5 includes a power supply circuit for supplying power to the LEDs 70, 70, 70 of the LED light source unit 7. When power is supplied from the battery 4, the LEDs 70, 70, 70 are turned on. The power to be generated is boosted to about 30 V, which is a voltage higher than the voltage value of the battery 4.

  The LED light source unit 7 is formed by connecting three LEDs 70 in series, and a transistor 8 is connected to one end side. The base of the transistor 8 is connected to a flashing control circuit 6 for supplying a pulsed drive signal so that the LEDs 70, 70, 70 flash.

  And in this embodiment, the LED light source part 7 is arrange | positioned so that it may be exposed from 10A of instrument main bodies. That is, the alternate long and short dash line in FIG. 1 indicates the instrument body 10A, and the charging circuit 2, the switching circuit 6, the battery 4, the booster circuit 5, the blinking control circuit 6, and the transistor 8 are each unit or a common unit. It is stored in the instrument body 10A. On the other hand, the alternate long and two short dashes line in FIG. 1 indicates the LED light source unit 7 and indicates that the LEDs 70, 70, and 70 are disposed on the instrument body 10A so as to be located outside the instrument body 10A. It is. In addition, in order to protect the outer surfaces of the LEDs 70, 70, 70, a cover (not shown) may be provided as appropriate so as to surround the LEDs 70, 70, 70.

  Next, the operation of this embodiment will be described.

  Normally, the switching circuit 3 is connected so that the power supply from the regular power supply 9 is connected to the battery 4 via the charging circuit 2, and the battery 4 is in a charged state by the charging current of the charging circuit 2. And the occurrence of a fire shall be notified to the signal apparatus 1 by the fire detector arrange | positioned at an appropriate position. Then, the signaling device 1 sends a control signal to the flashing emergency lighting device 10 installed in a passage suitable for an evacuation route, stairs, etc., to the switching circuit 3 of the flashing emergency lighting device 10 to notify the fire detector. Communicate information based on.

  Then, the switching circuit 3 switches so that the charging voltage of the battery 4 is supplied to the booster circuit 5. Next, the relatively low voltage boosted by the booster circuit 5 is supplied to the LEDs 70, 70, 70, and the flashing control circuit 6 turns on and off the base of the transistor 8, so that the LEDs 70, 70, 70 flash. As a result, the flashing emergency lighting device 10 is driven by the battery 4 and can be evacuated even when the regular power supply 9 becomes unavailable due to a fire or the like. For example, in addition to the normal emergency signal, the signal device 1 can transmit a signal for urging early condemnation. When this information is input to the switching circuit 3, the switching circuit 3 The control circuit appropriately changes the control state of the blinking control circuit 6.

  According to the present embodiment, the LED 70 is used as a blinking light source. Therefore, even when the surroundings are dark, the LED 70 blinks quickly in an emergency, and the evacuation direction can be notified to the evacuees, so that high safety can be ensured. Further, since the LED 70 has high responsiveness, the blinking operation can be started earlier. Therefore, the evacuation direction can be notified to the refugee at an early stage. Therefore, it can be set as the flashing emergency lighting apparatus 10 which can obtain high safety and high certainty.

  Further, since the step-up ratio by the step-up circuit 5 is low, the LEDs 70, 70, 70 can be arranged so as to be exposed outside the instrument body 10A. Thereby, since the direct light from LED70,70,70 can be widely radiated | emitted out of the instrument main body 10A, the visibility of a blinking state does not fall. In addition, since the direct light of the LEDs 70, 70, 70 is used for blinking notification, the luminance of the LEDs 70, 70, 70 is not increased more than necessary (low-energy LEDs can be used), so the battery is charged. The rate of voltage decrease can be suppressed, and long-time flashing can be maintained.

  Moreover, since it is possible to arrange the LED 70 outside the instrument main body 10A, the degree of freedom of design is widened. For example, a plurality of models can be selected according to the space where the flashing emergency lighting device is installed. Is possible.

  Similarly, since the boosting ratio by the boosting circuit 5 is low, energy loss that is wasted as a whole circuit can be reduced, so that circuit efficiency can be increased. Furthermore, since the pulse dedicated line used in the conventional xenon lamp is not necessary, the possibility of inconvenience due to disconnection can be avoided and the circuit can be simplified.

  In addition, since the blinking cycle of the LED light source unit 7 can be changed by the control of the blinking control unit 6, the blinking can be accelerated or the blinking interval can be lengthened as necessary, so that a change in situation can be easily notified. In addition, the range of use, functions, and applications can be expanded.
