Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an emergency lighting driving system having a distribution unit,

[0001] The present invention relates to an emergency lighting driving system for driving an emergency lighting by receiving a constant power supply and an emergency power supply, and more particularly, And more particularly to an emergency lighting drive system having a unit.

In general, elevators or stairs of apartments or buildings are equipped with sensors, which are illuminated by human access, and emergency lights, which are turned on during an emergency such as a power failure, to guide the evacuees to evacuate safely. However, in the case where a sensor and an emergency light are installed separately, an installation cost is large and space is not efficiently utilized. Recently, an emergency lighting apparatus has been disclosed in which a sensor and a emergency light are installed in a single lighting device.

For example, Korean Utility Model Publication No. 20-2010-0007750 discloses an emergency-light driving apparatus serving as an illumination lamp. When a normal AC power is supplied, an AC power source is applied to a motion detection sensor to turn on the LED lighting lamp In case of a power failure, the emergency garden, which is applied by the emergency power supply unit, is supplied to the DC power supply unit so that the LED lighting lamp is directly lit from the DC power supply unit. Such an emergency lighting apparatus can reduce the manufacturing cost and can reduce the labor cost at the time of construction.

However, in the event of a fire in a building, constant power is still supplied. In this case, since the emergency power source is in a cut-off state, the emergency power source is always supplied with power, and in this case, the emergency lighting device operates as a sensor. Therefore, before the human being approaches the emergency lighting apparatus, the detection signal of the motion detection sensor is absent, so that the LED illumination lamp is in the unlit state. In this case, it is difficult to find the passage due to the soot generated in the fire, so that the stomach can not safely prepare and cause a big loss of life.

Meanwhile, in recent years, an emergency lighting driving system has been developed to turn on an emergency light even in an emergency situation such as a fire, even when the constant power source is still alive. Figure 1 illustrates a conventional emergency lighting drive system.

As shown in the right side of Fig. 1, the emergency lighting devices 180 and 190 are installed in the respective layers of the elevator hall or the respective layers of the stairs. Each of the emergency lighting apparatuses 180 and 190 includes sensor lights 183 and 193 and emergency lights 185 and 195. As shown in the figure, the sensors 183 and 193 are turned on by the switching of the human body detection sensors 181 and 191. The human body detection sensors 181 and 191 are devices that switch the power source to the sensors 183 and 193 by sensing the approach of the human body. In the illustrated example, the human body detection sensors 181 and 191 are depicted as switches.

Hereinafter, the emergency illuminator 180 of the reference layer among the emergency illuminators 180 and 190 will be described as an example, and the circuit analysis applied to the emergency illuminator 180 of the reference layer will be applied to all the other layers as well.

The sensor 183 receives power from the constant power source 150 and the emergency light 185 receives power from the emergency power source 160. On the other hand, protective circuit breakers 155 and 165 are provided at the input terminal of the constant power source 150 and at the input terminal of the emergency power source 160, respectively.

At this time, as shown in FIG. 1, a fire monitoring panel 100 is installed. The fire monitoring unit 100 includes a battery 110 and a battery 110. The fire detector 120 is connected to the battery 110 through a fire detector 120 and a relay 130, And a magnetic switch 140 (MC) to be charged.

When the fire detector 120 is operated, power is applied to the magnetic switch 140 by the relay 130, and the magnetic switch main contact 145 (MCa) is turned on in the right side circuit diagram. Then, the constant power source 150 is immediately connected to the emergency light 185. Therefore, even if the emergency power source 160 is shut off because the fire is generated and the normal power source 150 is alive, the emergency light 185 of all the floors can be lighted.

However, the emergency lighting driving system of FIG. 1 may be configured such that the emergency light 185 is supplied to the constant power source 150, such as a sensor or the like, in order to maintain the lighting regardless of the operation of the human body detection sensor 181 when the emergency light 185 is turned on. (183). As shown in the drawing, the wiring passing through each layer is composed of two power lines 171 and 172, two power lines 173 and 174 from the emergency power source 160, four power sources Line.

That is, although the above-described problem of Korean Utility Model No. 20-2010-0007750 is solved, there is a problem that the number of the luminaire and the wiring is increased, the manufacturing unit cost and the labor cost are increased.

2 is a circuit diagram illustrating an emergency lighting drive system according to the present invention. Referring to FIG. 2, emergency lighting devices 280 and 290 are installed in each layer of the elevator hall, or each layer of the stairs. Each of the emergency lighting devices 280 and 290 includes a single illumination light 282 and 292 serving as a sensor and an emergency light and human detection sensors 284 and 294 connected in series to the illumination lights 282 and 292. The human body detection sensors 284 and 294 are devices that output a switching signal by sensing the approach of the human body. In the illustrated example, the human body detection sensors 284 and 294 are depicted as a switch type, but they may be configured as a contactless type. For example, the human body detection sensors 284 and 294 are sensing elements such as a frequency oscillation type, a capacitive type, and a magnetic type, and sense the approach of the human body and output a switching signal of a contactless or point-contact type.

Hereinafter, the emergency illuminator 280 of the reference layer among the emergency illuminators 280 and 290 will be described as an example, and the circuit analysis applied to the emergency illuminator 280 of the reference layer will be applied to all other layers as well.

As shown in the drawing, three power supply lines (CL, AL, EL) are wired to each layer. The power supply line connected to one side of the illumination lamp 282 is a common power supply line 610 and the power supply line connected to the other side of the human body detection sensor 284 is a constant power supply line 620, And an emergency power line 630 (EL) are branched from a connection point where one side of the human body detection sensor 284 and the other side of the human body detection sensor 284 are connected to each other.

The constant power source 250 is a constantly supplied power source and supplies constant power to the emergency lighting device 280 via the circuit breaker 255. The emergency power source 260 supplies emergency power to the emergency lighting device 280 via the circuit breaker 265 as a power source supplied in an emergency in which the constant power source 250 is cut off.

Three switches SA1, SA2 and SA3 and a distributing unit 300 are provided between the constant power source 250 and the emergency power source 260 and the emergency lighting device 280. [ Here, the three switches SA1, SA2, and SA3 are switches for performing a switching operation by the power source switching relay Ra of the distributing unit 300, and are installed inside the case where the distributing unit 300 is installed Or an external type which is installed outside the case. For example, in an emergency lighting drive system in which the distribution unit 300 is burdened with a large rated capacity, the switches are integrated to provide the distribution unit 300, and in an emergency lighting drive system having a small rated capacity, (300) can be configured more compactly.

The distribution unit 300 switches the first switch 312 to the third switch 316 to the left as shown in the drawing so that one side of the constant power source 250 is connected to the first switch 312 and the other side of the constant power source 250 is connected to the constant power source line 620 through the third switch 316. [ Accordingly, the emergency lighting device 280 is operated by the constant power source 250. At this time, the emergency illumination device 280 functions as a sensor or the like which is turned on in response to the switching signal of the human body detection sensor 284.

The distribution unit 300 switches the first switch 312 to the third switch 316 to the right so that one side of the emergency power source 260 is connected to the first switch 312, And the other side of the emergency power supply 260 is connected to the emergency power supply line 630 through the second switch 314. [ Accordingly, the emergency lighting device 280 is operated by the emergency power source 260. [ At this time, the emergency lighting device 280 functions as a emergency light that maintains the lighting regardless of the operation of the human body detection sensor 284.

On the other hand, in the emergency lighting drive system of the present invention, a fire is detected, but the emergency light can be turned on by the always-on power when the power is always on.

As shown in the left side of FIG. 2, a fire monitoring panel 200 is installed. The fire monitoring unit 200 includes a battery 210 and a fire detector 220 and a fire detector 220 connected in series to the battery 210. The fire detector 200 is connected to the fire detector 220 and the fire detector 220.

When the fire detector 220 is operated, the power of the battery 210 is turned on to the fire operation relay 230 and the relay main contact 235 (Rs) is turned on while the fire operation relay 230 is excited. As shown in the figure, the relay main contact 235 opens and closes the connection between the always-on power line 620 and the emergency power line 630. When the relay main contact 235 is turned on, the other side of the constant power source 250 is connected to the emergency lighting device 280 along the third switch 316, the constant power line 620 and the emergency power line 630 do. At this time, since the other side of the constant power source 250 is connected to the connection point of the illumination light 282 and the human body detection sensor 284, the illumination light 282 is turned on by the constant power source 250 regardless of the operation of the human body detection sensor 284 .

That is, even if the fire is generated and the constant power source is alive and the switching to the emergency power source is not performed, all the emergency lighting devices 280 and 290 can be turned on regardless of the operation of the human body detection sensor 284 .

The first photocoupler 420 is a phototransistor, and the transistor performs a non-contact switching operation when the power is always supplied.

The comparator 430 receives the operating power from the power input unit 510 and receives the reverse bias voltage of the first photocoupler 420 as a single input. The first photocoupler 420 is turned on in a state where the constant power source 250 is live and a low level signal is applied to the input terminal of the comparator 430. The output of the comparator 430 is also a low level signal. In this case, the second photocoupler 440 maintains the non-conduction state. The first to third switches 312, 314, and 316 all maintain a contact state to the power supply 250 side.

Specifically, when the constant power source 250 is cut off, the first photocoupler 420 is turned off, and the comparator 430 outputs a high level signal. Then, the second photocoupler 420 of the phototriac is turned on, and the second photocoupler switching unit 540 of the emergency power distributor 500 is turned on. The turn-on signal is applied to the gate terminal of the emergency power supply switching unit 530 composed of triac according to the turn-on operation of the second photocoupler switching unit 540, and the power supply relay 420 is energized, 1 to the third switches 312, 314, and 316 are switched to the emergency power source 260 side.

3, the equipotential circuit unit 600 is connected between one side of the output stage of the emergency power distributing unit 500 and the constant power line AL. In the emergency lighting driving system of the present invention, as shown in FIG. The equipotential circuit unit 600 is connected in parallel with the human body detection sensor 284 when the first to third switches 312, 314 and 316 are switched to the emergency power supply 260 side so that the equal potentials across the human body detection sensor 284 . Accordingly, it is possible to maintain the equal potential across the human body detection sensor 284 despite the switching operation, and the human body detection sensor 284 can be protected from the abnormal voltage induced during the switching operation.
