The present invention relates to an emergency lighting control device of an emergency light combined LED lighting lamp that is normally lit by a commercial power supply and then is turned on by an emergency power when the commercial power is cut off, and more particularly, to an emergency lighting control device by a semiconductor switching element, and By configuring resistance on the circuit connecting the emergency circuit part, the illuminance of the commercial lighting and the emergency lighting is different, the structure is simple, the emergency lighting is reliable, and the emergency lighting of the combined LED lighting that can be used as a dimming device by parallel connection of the commercial circuit part It relates to a control device.

In general, an emergency lighting combined lighting device is a lighting device that is normally turned on with a commercial AC power source and then turned on with power stored in a storage battery in an emergency such as a power outage of the commercial AC power. The emergency lighting combination lighting equipment is usually installed in a building such as a building, and the emergency lighting combination lighting system is installed selectively from among a number of lighting equipment to maintain the indoor lighting condition even in a dangerous situation such as a fire, so that the victims can safely evacuate. Do it.

Looking at the emergency lighting combined lighting device of the prior art, Republic of Korea Utility Model Publication No. 20-194852 emergency lighting power supply device (September 01, 2000) charges a certain amount of power to the storage battery through a storage battery charging circuit connected from a commercial power source. It is a system that turns on the emergency lamp connected to the high voltage generator through the AC relay when the supply of commercial power is interrupted by connecting the emergency lamp connected to the high voltage generator through the AC relay. There was a problem that the lighting time of the emergency light was shortened due to insufficient capacity due to the limit of the storage capacity, the emergency light was not turned on due to overdischarge of the storage battery, or the system was enlarged by a relay.

The present invention was created to solve the problems of the prior art described above, and the emergency lighting circuit unit has a simple structure, a small overall size, and a switching composed of a voltage divider and a MOSFET transistor or a silicon controlled rectifier in the emergency circuit to ensure the emergency lighting. It is intended to provide an emergency lighting control device for an emergency lighting combined LED lighting lamp in which the emergency power is conducted to the LED through the resistance by the trigger of the switching unit by configuring a resistance on the circuit connecting the unit and the commercial circuit unit.

The present invention includes a voltage regulator consisting of a diode (D2), a resistor (R7), a resistor (R8) sequentially configured in series in the emergency power supply; A DC level stabilization unit including a Zener diode (ZD1) connected in parallel to the emergency power line and ground; The resistor (R9) connected in parallel to the emergency power line and the capacitor (C6) connected in parallel to the emergency power line and configured at the rear of the resistor (R9) and the capacitor (C6) are configured in series with the emergency power supply. A voltage divider comprising a resistor R10; A switching unit composed of a MOSFET transistor (Q1) or a silicon controlled rectifier (SCR1) acting as a switch by the emergency voltage; and a resistor (R11) connected in series to the switching unit and the controller (U1: IC) of the converter. It consists of an emergency lighting illuminance control part.

The present invention has the effect of reducing the size of the system by not connecting the emergency power to a relay but by using a semiconductor switching device.

In addition, the present invention has an effect that the emergency lighting time is shortened due to the storage capacity of the storage battery or the emergency light is not turned on due to overdischarge of the storage battery because the storage battery is not used as an emergency power source.

In addition, the present invention is controlled by a single controller even if the commercial power and emergency power are input at the same time, so that no abnormality occurs electrically, and the illuminance of the LED at this time does not exceed the illuminance at the time of lighting by the commercial power.

In addition, according to the present invention, when a plurality of emergency circuit units are connected in parallel, it can be used as a dimming device.

Figure 1: Configuration of the emergency lighting control device of the present invention.
Figure 2: A configuration diagram of another embodiment using the silicon controlled rectifier of the present invention.

The present invention is a general emergency light combined LED lighting including a commercial circuit unit 10 configured with a rectifier circuit (BD1: Bridge Rectifier), a converter 20 configured with a controller (U1: IC), and a lighting unit 30 configured with an LED It consists of an emergency circuit unit 40 applicable to the emergency lighting control device.

The emergency circuit unit 40 includes an AC filter unit 41 that attenuates an instantaneous overvoltage or a surge current, an AC/DC conversion unit 42 that converts AC to DC, and a voltage control that converts the voltage of the current. A unit 43, a DC level stabilizing unit 44 for stabilizing the voltage of the current, a voltage distribution unit 45 for adjusting the voltage, and a switching unit 46 for allowing an emergency current to be conducted to the LEDs (LED1, LED2). Wow, it consists of an emergency lighting illuminance control unit 47 that adjusts with a current suitable for lighting of the LED (LED1 ~ LED2).

The AC filter unit 41 is turned on when a current flows to supply emergency power (H3, H4) to a plurality of LEDs (LED1, LED2) that generate light, from the AC current applied from the emergency power supply (H3, H4). The emergency circuit unit 40 is protected by attenuating overvoltage or surge current at the moment of occurrence. The AC filter unit 41 protects the elements of the emergency circuit unit 40 after the AC filter unit 41 against the AC current applied from the emergency power sources H3 and H4, and an input line of any one of the input AC power It is composed of an overcurrent protection fuse F2 configured in (H4), and an overvoltage protection varistor (VR2) configured in parallel to the emergency power source H3.H4 configured and inputted behind the fuse F2.

When the alternating current of the input commercial power sources (H1, H2) (H3.H4) exceeds a certain voltage, the varistor (VR2) decreases the resistance and flows current, that is, it becomes a By-Pass-Road. To prevent failure of the circuit unit 40. The varistor VR2 is configured to suppress an instantaneous voltage and discharge a high-voltage current. When the voltage exceeds the set voltage, the resistance value suddenly decreases and a large current flows through the input emergency power supply (H3, H4). It protects the circuit from transient overvoltage or surge current.

Regardless of the polarity of the applied voltage, the varistor VR2 may be formed of either a symmetric type varistor whose resistance is determined by the magnitude of the voltage and an asymmetric type varistor that varies depending on the polarity of the applied voltage.

The fuse (F2) is configured to protect the emergency circuit unit 40 by being short-circuited when either of the allowable voltage or the allowable current exceeds the allowable value, and the fuse (F2) may be configured at the rear of the varistor (VR2). In this case, since it is difficult to protect the varistor VR2 even if the fuse F2 is short-circuited, it is preferable to configure the fuse F2 in front of the varistor VR2.

The AC/DC conversion unit 42 is composed of a bridge rectifier (BD2) consisting of four diodes for rectification by inputting the AC applied from the AC filter unit 41 and converting it to DC. It is connected to the power line after the bridge rectification circuit BD1 of the circuit unit 10. The anode of the bridge rectifier circuit (BD2) is connected to the anode of the commercial circuit unit (10) and the cathode of the bridge rectifier circuit (BD2) is connected to the cathode of the commercial circuit unit (10) and emergency power supply (E3, E4) It is configured to be input to the commercial circuit unit 10 to use a commercial circuit.

The voltage control unit 43 converts the voltage of the current applied from the emergency power supply (H3, H4) into a voltage suitable for the switching unit 46 and is connected to any one input line (H4) of the emergency power supply (H3, H4). It is composed of a diode D2, a resistor R7, and a resistor R8 sequentially configured in series.

The diode (D2) of the voltage control unit (43) rectifies the emergency current of the emergency power supply (H3, H4) while flowing in the direction of the DC level stabilization unit (44), and the resistance (R7) and the resistance (R8) are emergency. The current is sequentially limited and controlled, and conduction is suppressed when the emergency current is an overvoltage of a certain value or more, and conducts when the voltage is less than a set value, and is applied to the DC level stabilizer 44.

The DC level stabilization unit 44 is composed of a Zener diode (ZD1) connected in parallel to any one line of the emergency power supply (H3, H4) and ground, and adjusts the voltage for the current applied from the voltage control unit 43. Drop and adjust to stabilize the voltage. Since the Zener diode ZD1 controls a specific voltage to flow current in the reverse direction (break down), due to its characteristics, when a certain reverse voltage is applied, it flows a current to lower the resistance so that the voltage does not increase at that point.

When a normal voltage is applied to the gate of the MOSFET transistor (Q1; field effect transistor) of the switching unit 46, the Zener diode ZD1 does not conduct a current. When a certain voltage or more is generated in the gate of the transistor Q1, the overvoltage current flows to the ground through the Zener diode ZD1, and the voltage of the DC current of the gate of the MOSFET transistor Q1 does not rise. In other words, the Zener diode ZD1 prevents the MOSFET transistor Q1 from operating when an overvoltage occurs in the gate of the MOSFET transistor Q1.

The voltage divider 45 is a capacitor connected in parallel to a resistor R9 connected in parallel to an anode and a cathode, and a capacitor connected in parallel to an anode and a cathode, and configured at the rear of the resistor R9. It is composed of (C6) and a resistor (R10) configured at the rear of the capacitor (C6) and configured in series with either of the emergency power supply (H3, H4) lines.

The resistor R9 and the resistor R10 are regulated by limiting the current and voltage output from the voltage regulator 43, and the resistor R9 is a current smaller than the voltage value of the gate of the MOSFET transistor Q1 to the cathode. The MOSFET transistor Q1 is not triggered by bypassing, and the resistor R10 sends a current greater than the voltage value of the gate of the MOSFET transistor Q1 to the gate of the MOSFET transistor Q1, Q1) is triggered, and the capacitor (C6) is generated by the emergency power supply (H3, H4), that is, the DC level of the emergency power supply (H3, H4) by removing noise components that may occur when triggering the MOSFET transistor (Q1). Is stabilized to supply a stable current to the MOSFET transistor Q1.

The switching unit 46 is composed of a MOSFET transistor Q1, and an emergency voltage is applied to the gate of the MOSFET transistor Q1 of the switching unit 46 via the resistors R9 and R10, and the resistors R9 and R10 As the transistor Q1 is distributed and supplied by ), the transistor Q1 is turned on. In the MOSFET transistor Q1, a gate is connected to a resistor R10 of a voltage divider 45, a drain is connected to a resistor R11 of the emergency lighting control unit 47, and a source ) Is grounded.

The MOSFET transistor (Q1) flows or blocks current according to the trigger of the gate, and the MOSFET transistor (Q1) acts as a switch. When using commercial power sources (H1, H2), the emergency power supplies (H3, H4) are MOSFET transistors. Since the gate voltage of the MOSFET transistor Q1 is not inputted to (Q1), the gate voltage of the MOSFET transistor Q1 is in a low state, and the MOSFET transistor Q1 is not triggered and the LEDs (LED1 to LED2) are not turned on. The switching unit 46 is made of a semiconductor switching element, not a relay, so that the size of the system is reduced.

When the commercial power (H1, H2) is cut off and the emergency power (H3, H4) is turned on (ON), the gate voltage of the MOSFET transistor (Q1) is changed to a high state by the emergency power (H3, H4) and becomes a high signal. Therefore, the MOSFET transistor Q1 is triggered, and the emergency power sources H3 and H4 are transferred to the converter 20 through the drain and resistor R11 of the MOSFET transistor Q1, and the LEDs LED1 to LED2 are turned on. .

When the MOSFET transistor (Q1) is triggered, current flows in the forward direction until the gate voltage disappears, so once it is turned on, it is maintained until the emergency power supply (H3, H4) is shut off, and continues to maintain the turn on mode. Therefore, the LEDs (LED1~LED2) are continuously turned on, and when the emergency power (H3, H4) is turned off or the commercial power (H1, H2) is input, the LEDs (LED1~LED2) are turned off.

The condenser C6 stabilizes the gate current of the transistor Q1 by accumulating noise that may occur when the MOSFET transistor Q1 is triggered by the input of the emergency power supplies H3 and H4 and lowering the noise voltage. As the voltage-controlled current continues to accumulate in the condenser C6, the voltage of the condenser C6 rises, and when the current stored in the condenser C6 reaches the gate voltage of the MOSFET transistor Q1, the condenser C6 The current is discharged at and the discharged current is sent to the gate of the MOSFET transistor Q1 to trigger the MOSFET transistor Q1.

When the MOSFET transistor Q1 is triggered, the ground of the emergency circuit, that is, the ground of the voltage divider 45 and the ground of the converter 20, that is, the ground of the DC level stabilizer 44 and the ground of the converter 20, that is, Since the current of the ground (GND) of the controller (U1: IC) is the same, when a resistance is formed in the circuit connecting the emergency circuit unit 40 other than the commercial circuit unit 10, the current of the commercial circuit is controlled by the resistance value. do.

The emergency lighting illuminance control unit 47 is configured with a resistor R11 connected in series to the controller (U1: IC) of the converter 20 and limited to a current value suitable for lighting of the LEDs (LED1 to LED2). Since the resistor R11 can apply the current applied from the MOSFET transistor Q1 to the converter 20 and limit the current value, the LED at the time of emergency lighting according to the resistance value of the resistor R11 can be used. Determine the illuminance of LED2).

In the case of the emergency lighting, emergency power (E3, E4) is input to the commercial circuit unit 10 to use a commercial circuit, but the current limited by the resistance R11 is input to the converter 20, so the commercial lighting and emergency lighting The illuminance of will be different. When the resistance R11 is connected in the same form as the sensing resistors R4 and R5 of the commercial circuit unit 10, the illuminance of the LEDs (LED1 to LED2) by the commercial circuit unit 10 and the LED by the emergency circuit unit 40 ( The illuminance of the LED1 to LED2 is the same, but the resistance R11 is configured on the circuit connecting the commercial circuit unit 10 and the emergency circuit unit 40, so that the illuminance of the commercial lighting and the emergency lighting is different.

The controller (U1: IC) operates the entire circuit by receiving direct current from the bridge rectifier circuit (BD1) of the commercial circuit unit 10 and the bridge rectification circuit (BD2) of the emergency circuit unit, and operates the current of the emergency lighting illuminance control unit 47. Input is applied to the LEDs (LED1~LED2) so that the LEDs (LED1~LED2) emit light, that is, turn on.

As another embodiment of the present invention, the MOSFET transistor Q1 of the switching unit 46 may be configured as a silicon controlled rectifier (SCR1) of the switching unit 46-1. The silicon control rectifier (SCR1) is connected in series to any one of the emergency power lines (H3, H4), and the commercial power (H1, H2), that is, when the commercial current is input, the emergency power (H3, H4) is turned off ( OFF) and there is no trigger signal at the gate of the silicon control rectifier (SCR1), so when the silicon control rectifier (SCR1) is not turned on, the emergency current is turned to the LED (LED1~LED2). The LED (LED1~LED2) is turned on by the commercial current because it is not energized.

When an abnormality occurs in the commercial power supply (H1, H2) and the commercial current is turned off (OFF) and the emergency power supply (H3, H4) is turned on (ON), the emergency current becomes a trigger signal to the gate of the silicon control rectifier (SCR1). Silicon control rectifier (SCR11) is turned on (Turn on), commercial current is applied to the lighting unit 30 through the converter 20, the LEDs (LED1 to LED2) are turned on by the emergency current.

The resistor R9 and the resistor R10 are controlled by limiting the current and voltage output from the voltage control unit 43, and the resistor R9 is the cathode current smaller than the gate current value of the silicon control rectifier SCR1. The gate of the silicon control rectifier (SCR1) is not turned on by bypassing it, and the resistance R10 is the gate of the silicon control rectifier (SCR1). The gate of the silicon control rectifier (SCR1) is turned on, and the capacitor (C6) is generated by the emergency power supply (H3, H4), that is, when the silicon control rectifier (SCR11) is turned on. By removing possible noise components, the DC level of the emergency power supply (H3, H4) is stabilized, and a stable current is supplied to the silicon control rectifier (SCR1).

Since the silicon control rectifier (SCR1) flows or blocks current according to the operation of the gate, the gate of the silicon control rectifier (SCR1) acts as a switch, so the gate is turned on by the input of the emergency power supply (H3, H4). on), that is, the capacitor C6 accumulates noise that may occur when the switch is turned on, thereby reducing the noise voltage, thereby stabilizing the DC current that is changed in the AC/DC converter 41 and inputted.

The lighting unit 30 is connected to the converter 20, and a plurality of LEDs (LED1 to LED2) are mounted directly, so that the LEDs (LED1 to LED2) are turned on according to the power input (ON) of the converter 20.

The converter 20 converts the AC of the commercial power sources H1 and H2 and the emergency power sources H3 and H4 into direct current and outputs the converted current into a current suitable for the LED modules LED1 and LED2. When the current input to the commercial power sources H1 and H2 is input to the input terminal of the converter 20 through the bridge diode BD1, the converter 20 converts into a set first current, that is, a commercial lighting current, and outputs it to the output terminal. When the current input to the emergency power sources H3 and H4 is input to the input terminal of the converter 20 through the bridge diode BD2, it is converted into a set second current, that is, the emergency lighting current, and output to the output terminal.

At this time, the commercial power (H1, H2) and emergency power (H3, H4) may be AC power of the same size, for example, the commercial power (H1, H2) is each from a power supply source such as external (KEPCO). AC 220V power supply supplied to households, and emergency power (H3, H4) is, for example, AC 220V power supply of emergency generators supplied to each household in case of emergency.

Since the emergency power (H3, H4) is supplied from the emergency generator, there is no problem that the emergency lighting time is shortened due to the storage capacity of the storage battery or the emergency light is not turned on due to overdischarge of the storage battery because the storage battery is not used. The AC power of the commercial power sources H1 and H2 and the emergency power sources H3 and H4 and the DC current output from the converter 20 may have various sizes.

When the AC of the commercial power sources H1 and H2 is converted and output from the bridge diode BD1 is always supplied to the converter 20 and an abnormality such as a power failure occurs in the commercial power sources H1 and H2 The supply of DC from the bridge rectifier circuit (BD1) to the converter 20 is stopped, and at this time, AC is input to the emergency power sources (H3, H4) by the operation of an emergency generator, etc., and from the Braji rectifier circuit (BD2) to DC It is converted and input to the converter 20 by the switching operation of the switching element [(MOSFET transistor: Q1) or (silicon controlled rectifier: SCR1)].

LEDs (LED1, LED2) are turned on by the output of the converter 20, and commercial lighting by the commercial power sources (H1, H2) is performed by the commercial circuit unit 10, and emergency power sources (H3, H4) The lighting is turned on by the emergency circuit unit 40 and the commercial circuit unit 10 while the emergency circuit unit 40 is connected to the commercial circuit unit 10, but the illuminance of the emergency light is determined by the emergency circuit unit 40.

In other words, the commercial lighting is turned on by energization by the commercial circuit unit 10, and the emergency lighting is performed using the commercial circuit unit 10, but the commercial power supply (H1, H2) and the bridge diode (BD2) are not used. BD2) and subsequent emergency circuits are used to light up, and therefore, the emergency lighting is determined by the emergency circuit section 40 by the resistance R11 of the emergency circuit section 40.

The emergency circuit unit 40 may be set so that the illumination of the commercially lit LEDs (LED1, LED2) is turned on at 30W, and the LEDs of the emergency lighting (LED1, LED2) are lit at 20W. Each of the plurality of emergency circuit units 40 can be connected to the commercial circuit unit 10 by making a plurality of the emergency circuit units 40 in parallel, and in this case, the illuminance of the emergency lighting can be varied. That is, LEDs (LED1, LED2) are turned on by 30W by the commercial circuit unit 10, LEDs (LED1 and LED2) are turned on by 20W by the first emergency circuit unit, and LEDs (LED1 and LED2) are turned on by the second emergency circuit unit by 15W. , LEDs (LED1, LED2) can be turned on by 10W by the third emergency circuit.

Illumination is determined by the current input to the commercial circuit unit 10 of the commercial lighting, but the emergency lighting is determined by the current of the emergency circuit unit 40 connected to the commercial circuit unit 10, and the size is commercially available in the emergency circuit unit 40. It is determined by the resistance R11, which is an element of the circuit supplied to the circuit unit 10.

In the present invention, even if the commercial power (H1, H2) and the emergency power (H3, H4) are input at the same time, since it is controlled by one controller (U1: IC), electrical abnormality does not occur, and the LED (LED1, LED2) at this time The illuminance is the same as the illuminance at the time of lighting by the commercial power supply (H1, H2).

The present invention can be used as a dimming device, in this case, the first switch to the commercial power (H1, H2) and the supply source of the emergency power (H3, H4) is the same as the commercial power (H1, H2), the external power (KEPCO), etc. When the second switch is configured as a supply source and the second switch is configured in this power supply source, when the first switch is turned on while the second switch is off, the LED (LED1, LED2) is driven only by the commercial circuit unit 10. ) Is turned on at 30W, and when the second switch is turned on while the first switch is turned off, the LEDs (LED1, LED2) can be turned on at 20W by driving the emergency circuit unit 40. It becomes the first stage dimming.

Dimming can be varied by connecting a plurality of emergency circuit units 40 to the commercial circuit unit 10 in parallel. For example, the LEDs (LED1, LED2) are configured to be turned on at 30W by the commercial circuit unit 10, 20W by the first emergency circuit unit, 15W by the second emergency circuit unit, and 10W by the third emergency circuit unit.

That is, if the commercial power supply (H1, H2) is connected to the first switch, the second switch to the first emergency circuit part, the third switch to the second emergency circuit part, and the fourth switch to the third emergency circuit part, the 2nd, 3rd, 4th When the first switch is turned on while the switch is off, the LEDs (LED1, LED2) are turned on at 30W by the commercial circuit unit 10 of the commercial power supply (H1, H2), and the first and third ,If the second switch is turned on while the 4 switch is off, the LEDs (LED1, LED2) are turned on at 20W by the first emergency circuit, and the first, second, and fourth switches are turned off. ) When the 3rd switch is turned on, the LEDs (LED1, LED2) are turned on at 15W by the second emergency circuit, and the 4th switch is in the state where the 1st, 2nd and 3rd switches are off. When is turned on, the LEDs (LED1, LED2) are turned on at 10W by the third emergency circuit unit 40 to implement 3-stage dimming.

Dimming of the LEDs (LED1, LED2) using the present invention is not composed of a dimming device that adjusts the brightness of the lighting by changing the current applied to the LED due to the change of resistance due to the rotation of the general dimming rotary cock. It is a dimming method in which a signal is transmitted by the method of turning on (0n) and off (off) the switch using a nine, three or four-hole switch, and the brightness of a lamp is determined by the signal. In other words, it becomes multi-level dimming of LED lighting using a wall switch.

The present invention can be applied to a general commercial lighting circuit including a commercial circuit unit, a converter, and a controller (IC), so descriptions of the commercial circuit unit 10, the converter 20, and the controller (U1: IC) will be omitted.
