  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
The illumination method according to this embodiment will be described with reference to FIGS. The illumination method according to the present embodiment is an illumination method for illuminating, for example, a space R (see FIG. 2) serving as an evacuation route when an abnormal state such as a fire or an earthquake occurs. In this lighting method, as shown in FIG. 2, the emergency lighting device 10 (first emergency lighting device) according to the present invention and the conventional emergency lighting devices 20, 20 (second emergency lighting device) are provided. Use to illuminate the space R.

  Each of the emergency lighting fixtures 10 and 20 operates based on power supply from the commercial power supply AC, and is embedded in the ceiling surface of the space R with the lower side as an illumination area. The illumination area of the emergency lighting apparatus 10 is set so as to include at least an area important in the space R as an evacuation route (in the vicinity of the stairs S in the drawing). Further, the illumination areas of the emergency lighting apparatuses 20 and 20 are set by the two emergency lighting apparatuses 20 so that the entire space R becomes an illumination area.

As shown in FIG. 1, the emergency lighting apparatus 10 includes a control unit 1, a charging circuit 2, a storage battery 3 (first storage battery) , a switch 4, and a lamp 5 (first light source) as its constituent elements.

  The control unit 1 includes a detection circuit (not shown) that detects whether power is supplied from the commercial power source AC. The control unit 1 determines that an abnormal state has occurred when the power supply from the commercial power supply AC is stopped without turning on the lamp 5 in a normal state while the power supply from the commercial power supply AC is being performed. After a predetermined waiting time T1 has elapsed, the lamp 5 is turned on to illuminate a part of the space R. In addition, the control unit 1 operates using the charging circuit 2 as a power source when power is supplied from the commercial power source AC, and operates using the storage battery 3 as a power source when the power supply from the commercial power source AC is stopped.

  The charging circuit 2 is an AC-DC conversion circuit that converts AC power from the commercial power source AC into DC power, and feeds the converted DC power to the control unit 1 and the storage battery 3 with DC power. The charging circuit 2 is connected to a diode for preventing backflow, and is set so that the current from the storage battery 3 does not flow back into the charging circuit 2 when the AC power from the commercial power supply AC is stopped. .

  The storage battery 3 is set to an electric capacity that can be lit at least for a predetermined lighting time T2 (for example, 30 minutes) when the lamp 5 is turned on from a fully charged state. When power is supplied from the commercial power supply AC, the storage battery 3 is charged by the DC power supplied from the charging circuit 2 and is always kept fully charged.

  The switch 4 is connected in series in the electric path from the storage battery 3 to the lamp 5. The switch 4 opens and closes the above-described electric circuit in accordance with a control signal from the control unit 1, and turns off / on the power supply from the storage battery 3 to the lamp 5.

  The lamp 5 is composed of a light source with low power consumption, such as a light emitting diode, and is lit by DC power supplied from the storage battery 2.

  The control unit 1 includes timer means 1a that measures the lapse of the standby time T1. Here, the waiting time T1 is set to a time equal to or shorter than the lighting possible time T3 in the emergency of the emergency lighting fixture 20, and is set to 30 minutes in the present embodiment.

  Further, when the control unit 1 detects the stop of the power supply from the commercial power supply AC, the control unit 1 starts the timer means 1a to start measuring the standby time T1, and when the standby time T1 elapses, the control unit 1 turns on the switch 4 to turn on the lamp 5 Lights up. Further, when power is supplied from the commercial power supply AC, the control unit 1 turns off the switch 4 and turns off the lamp 5.

The emergency lighting fixture 20 is a conventional emergency lighting fixture and has the same configuration as the emergency lighting fixture 10 described above except that the control unit 1 does not include the timer means 1a. That is, the emergency lighting fixture 20 immediately turns on the lamp 5 (second light source) when the power supply from the commercial power supply AC is stopped, and the lamp is discharged until the power stored in the storage battery 3 (second storage battery) is discharged. 5 is lit continuously.

  Here, the storage battery 3 of the emergency lighting device 20 continuously turns on the lamp 5 for at least a time (lighting possible time T3) longer than the time (30 minutes) stipulated by laws and regulations after the lighting of the lamp 5 is started. It is set to the electric capacity that can be lit.

  Here, the lighting method according to the present embodiment will be described by paying attention to the operation of each emergency lighting fixture 10, 20. 3A shows a change in the state of each component of the emergency lighting fixture 10 over time, and FIG. 3B shows the main parts of the emergency lighting fixtures 20 and 20 over time. The change of the state of a component is shown. Further, description will be made assuming that the power supply from the commercial power supply AC is stopped due to a power failure or the like at time t1 shown in FIGS. 3 (a) and 3 (b).

  First, during the normal power supply from the commercial power supply AC (on the left side of the time t1 in FIGS. 3A and 3B), the storage batteries 3 of the emergency lighting fixtures 10, 20, and 20 are The battery is charged by the power supplied from the charging circuit 2 and is kept fully charged. At this time, the switch 4 of the emergency lighting fixture 10 is set to the off state by the control unit 1, and the lamp 5 is kept in the off state. Note that the lamps 5 of the emergency lighting fixtures 20 and 20 may be turned on or off. For example, in a situation where there are other lighting fixtures in the surroundings, the lamps 5 are set to the off state. What is necessary is just to set to a lighting state, when there is no instrument.

  Here, when the power supply from the commercial power supply AC is stopped (time t1), the control unit 1 of the emergency lighting fixtures 20 and 20 sets the switch 4 to the on state, and turns on the lamp 5 using the storage battery 2 as a power source. (See FIG. 3B). Moreover, the emergency lighting fixture 10 starts the timer means 1a and causes the timer means 1a to start measuring the waiting time T1.

  Thereafter, when a predetermined standby time T1 elapses (time t2), the control unit 1 of the emergency lighting fixture 10 sets the switch 4 to the on state, and turns on the lamp 5 using the storage battery 2 as a power source (FIG. 3 ( see a)). At this time, since the waiting time T1 is set shorter than the lighting possible time T3 of the emergency lighting fixture 20, the lamp 5 of the emergency lighting fixture 10 is turned on while the lamp 5 of the emergency lighting fixture 20 is turned on. Can be lit.

  Thereafter, when the lighting possible time T3 has elapsed since the supply of electric power from the commercial power supply AC is stopped (time t3 in FIG. 3B), the storage battery 3 of the emergency lighting fixture 20 has a voltage at which the lamp 5 can be lit. Supply cannot be performed, and the lamp 5 of the emergency lighting fixture 20 is turned off. At this time, the lamp 5 of the emergency lighting fixture 10 continues to be lit using the storage battery 3 as a power source.

  Then, when the lighting time T2 elapses after the lamp 5 of the emergency lighting fixture 10 starts lighting (time t4), the voltage value of the storage battery 3 of the emergency lighting fixture 10 decreases, and the emergency lighting fixture 10 The lamp 5 is turned off.

  As described above, as soon as the power supply from the commercial power supply AC is stopped, the lamp 5 of the emergency lighting fixture 20 is turned on to illuminate the entire space R. Thereafter, the lamp 5 of the emergency lighting fixture 10 is turned on until the lamp 5 of the emergency lighting fixture 20 is extinguished (that is, until the lighting possible time T3 elapses), and the evacuation route in the space R. As an important area to illuminate. And even after the lamp 5 of the emergency lighting fixture 20 is turned off, the lamp 5 of the emergency lighting fixture 10 continues to be lit.

  In this way, at least an area important as an evacuation route is illuminated over a time obtained by adding the waiting time T1 and the lighting time T2, and the lighting can be secured for a longer time in an emergency. Moreover, compared with the case where the capacity | capacitance of the storage battery 3 of all the emergency lighting fixtures 20 and the number of cells are increased, the capacity | capacitance of the storage battery 3 as a whole can be restrained to low capacity, and cost reduction and space saving are achieved. be able to.

  The emergency lighting apparatus 10 may blink the lamp 5 until the standby time T1 elapses after the supply of power from the commercial power supply AC is stopped. In this way, the emergency lighting apparatus 10 can notify the surroundings that the supply of power from the commercial power source AC has been detected, and can prompt the surrounding people to make a decision such as evacuation. In this case, as shown in FIG. 4, the emergency lighting apparatus 10 consumes power from the time when the lamp 5 starts blinking, so that the electric capacity of the storage battery 3 is slightly larger than that in the case where it is not blinked. You only have to set it.

(Embodiment 2)
An illumination method according to this embodiment will be described with reference to FIGS. In the illumination method according to the present embodiment, the illumination region R is illuminated by detecting the occurrence of an abnormal state based on an emergency signal indicating an emergency such as a fire. The emergency lighting apparatus 10 used in this lighting method includes a signal detection unit 1b that detects an emergency signal that is input from the outside and that indicates an emergency such as the occurrence of a fire, for example, in the control unit 1 (see FIG. 5). Except for this point, the configuration is the same as that of the first embodiment, so the common components are denoted by the same reference numerals and description thereof is omitted.

  When the signal detection unit 1b detects an emergency signal at time t1, the control unit 1 causes the timer unit 1a to start measuring the standby time T1 regardless of whether power is supplied from the commercial power source AC (see FIG. 6). Thereafter, the control unit 1 sets the switch 4 to the on state at the time t2 when the standby time T1 has elapsed from the time t1 when the emergency signal is detected, and turns on the lamp 5 using the storage battery 3 as a power source.

  By doing in this way, although the power supply from commercial power supply AC does not stop at the time of a fire, etc., when the evacuation route needs to be illuminated, the space R can be illuminated, and illumination can be ensured for a longer time in an emergency.
