Battery Overcharge / Discharge Control Device for Emergency Lightings {Battery Control Unit For Extraordinary Lighting Lamp}

The present invention relates to an emergency lighting device in which the current is controlled after the battery is charged to prevent overcharging and the emergency lighting is blocked by the over-discharge prevention circuit part after the battery is discharged. More specifically, the battery is stabilized at a large capacity, for example, 5 A or more. The present invention relates to a battery overcharge / discharge control device for an emergency lighting lamp capable of charging and discharging in a state and capable of lighting a high brightness emergency lighting lamp for a long time.

In general, emergency lights illuminate the lamps for a certain period of time by using the battery built in the emergency lights installed in the high-rise buildings, government offices, sports stadiums and concert halls. You can find it. For example, emergency lighting used for stairs or evacuation passages in apartments or buildings uses energy-saving three-wavelength bulbs to save power, but it is expensive, and most of them use automatic sensor switches to turn on for only a certain time when people pass by. I have been power saving.

However, although the sensor lamp is not turned on at all times for 24 hours, it will save electricity, but it may turn on and off repeatedly, which may cause the evacuation in case of an emergency, and in case of fire, the sensor operation may be slowed down by mist. It is becoming. In addition, when electricity was cut off due to a fire, many people were injured in the event of a fire because they did not fully play the role of emergency lighting to safely evacuate people on stairs or emergency passages in case of an emergency such as a fire.

In light of these circumstances, the present applicant has variously developed emergency lightings for lighting an illumination lamp with a rechargeable battery in case of power failure. That is, emergency lighting, which is provided for safe and smooth evacuation activities and continuous work in case of power failure or other emergency caused by fire, is usually equipped with a secondary battery which is a rechargeable battery for emergency use. Therefore, it is usually designed to be turned on through a commercial power source and then switched to an emergency power source to be used as an alternative to the above-described secondary charging battery when the commercial power source is out of power.

On the other hand, if a power failure or other emergency occurs due to a fire while the rechargeable battery secondary battery is well charged, the emergency lighting is turned on by the power of the rechargeable battery, enabling safe and smooth evacuation in an emergency. Will be. Although these emergency lights are lit and fully discharged for more than 20 minutes, they meet current fire methods that must be recharged within 48 hours. However, most emergency lights, such as fires, have a power outage and discharge the rechargeable batteries such as emergency lights. After the recharge will occur within the time that can not be recharged emergency lighting is not useless.

For example, in places where power failures occur frequently due to the aging of electric facilities in Hanok or underdeveloped areas, the power supply of the rechargeable battery is discharged by the lighting of emergency lighting caused by the first power failure, and the power failure again occurs when the rechargeable battery is not charged again. In this case, since the rechargeable battery does not turn on the emergency light, a problem arises in that it does not function as an emergency light in an emergency situation.

Since the charging of the rechargeable battery takes a long time of 12 to 15 hours, the rechargeable battery is well charged only when the commercial power is stably supplied to the rechargeable battery during this time. However, not only are the risks of an emergency occurring in each business, home, or factory that uses emergency lighting, but also the frequency of power outages caused by the emergency is different, so emergency lights are installed where frequent emergency or blackouts occur. In the case of the emergency battery lamp is not charged, the occurrence of a power outage caused by a variety of emergencies such as fire or other factors, and the emergency lamp is impossible to turn on, so it is necessary to adjust the charging time of the rechargeable battery. Will be.

The present invention has been invented in view of the above circumstances, and for emergency lighting which can prevent an accident in advance so that the lights of the emergency lighting lamp according to the overcharge and discharging of the battery do not unsafely light in an emergency situation where the emergency lighting lamp should be turned on. The purpose is to provide a battery overcharge and discharge control device.

Another object of the present invention is to adjust the charging time of the battery to correspond to the chargeable time according to the power failure environment, it is possible to easily charge the battery in the place where the power failure occurs frequently, and to simplify the circuit configuration to reduce the weight of the product It is possible to provide a battery overcharge / discharge control device for emergency lighting which can be used semi-permanently for a long time by reducing unnecessary power consumption and minimizing the failure rate due to overcharge / discharge.

In the present invention for achieving the above object, in the emergency lighting device is configured to be connected to the light through the relay when the commercial power is supplied, the pre-power battery is automatically charged, the commercial power is cut off in case of power failure or emergency, The thyristor (SCR) and the capacitor (C6) normally filter the DC power to the battery, and maintain a constant voltage by the 555 timer IC (A1) and the zener diode (D15), and the relay (RL2) is contacted to charge the battery. A charging unit; An overcharge control unit configured to control current by the left and right op amps A2 and the zener diodes D17 when the battery voltage rises during charging; When the light is turned on, the relay RL1 is energized by the zener diode D18 and the turn-off transistor Q2, and the relay contact rl2 is shorted to short the connection between the battery and the light, thereby preventing overdischarge. Characterized in that the pre-protection circuit is configured to be connected.

As described above, according to the present invention, the charging time can be adjusted according to the chargeable time of the battery. Emergency lighting can be turned on to ensure safe and smooth evacuation activities.

According to the present invention, even when used in a place where frequent blackouts occur due to deterioration of electric facilities in hanok or underdeveloped areas, the light (emergency lighting) is not turned on due to uncharging of the battery in an emergency situation in which the emergency lighting should be turned on. It is effective in preventing accidents.

In addition, the present invention can adjust the charging time of the rechargeable battery to correspond to the chargeable time according to the electrostatic environment, it is possible to easily charge the battery even in frequent blackouts, and to simplify the circuit configuration to reduce the size and light weight of the product unnecessary power In addition to reducing the consumption, it also has the effect of long-term use permanently by minimizing the failure rate.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram illustrating a battery overcharge and discharge control device for emergency lighting according to an embodiment of the present invention, the present invention is controlled after the completion of the charging of the battery 50 to prevent overcharge and after the end of battery discharge Emergency lighting device that the emergency light is cut off by the over-discharge prevention circuit part 30, which can be charged and discharged in a large capacity, for example, the battery 50 of 5 A or more in a stabilized state, the high-brightness emergency light (60) It is a battery overcharge / discharge control device for emergency lighting that can light up for a long time.

Emergency lighting device with a built-in battery 50, a backup power storage battery, remove the rear cover and connect the battery terminals (B +, B-) with the charging unit 20, and then supply the AC 220V power to the power terminal (10) ). At this time, when installing the emergency light (60), the screw is installed on the wall surface to be fixed in accordance with the screw hole on the back of the emergency light, when adjusting the angle of the light (60) can be used to adjust the head of the emergency light up, down, left and right. have.

In addition, the battery 50 is connected to the over-discharge prevention circuit unit 30 and the lights 60 of the terminals L- and L +, respectively, while the overcharge control unit 40 is connected to the red lamp 62 of the monitoring lamp and the green. The lamps 64 are connected to each other. At this time, when the connection part of the battery 50 is shorted or there is no battery 50, the red lamp 62 of the terminal L2 is turned on. When the AC power is connected, the green lamp 64 of the terminal L1 is turned on. Lights up.

When commercial power is connected, the battery 50 is automatically charged through the power supply unit 10 and the charging unit 20. When the charging of the battery 50 is completed, the power supply is controlled so as not to overcharge the battery 50 automatically by the overcharge control unit 40. In the power failure, the high-brightness light 60 is turned on and the light 60, which is a high-brightness emergency light, is turned on for a long time using a power source of the battery 50. The over-discharge prevention circuit unit 30 operates to block the lighting and the red lamp 62 is turned on.

Figure 2 is a detailed circuit diagram showing a battery overcharge and discharge control device for emergency lighting of the present invention.

Commercial power AC 220V is supplied to the transformer PT57 of the power supply unit 10 through the fuse (F1) and the power push switch (PS), AC 16V is induced to the secondary side and the onion current by the diode (D9-D12) DC power is obtained. The power converted to direct current from the power supply unit 10 is filtered by the capacitor C6 to the full direct current power, and through the thyristor SCR of the charging unit 20, the 555 timer IC A1, and the relay contact rl2. The battery 50 is automatically charged. At this time, the light 60 is not turned on, and the green lamp 64 through the resistor R4 is turned on, indicating that the battery 50 is being charged from the outside.

As the 555 timer IC A1 in the charging unit 20 is input with the transistors T3 and T4 branched between the resistors R35 and R34 by the zener diode D16, the signals ⑤-⑧, The thyristor SCR and the relays RL1 and RL2 are operated by the zener diode D14 and the transistor T7 connected to the output terminal ③. Power supplied by the gate of the thyristor SCR is maintained by the 555 timer IC A1 and the zener diode D15 to maintain a constant power supply through the contact rl2 and the fuse F2 of the relay RL2. The battery 50 is automatically charged.

When the battery power rises while the preliminary power source battery 50 is being charged, the current is controlled by the two op amps A2 and the zener diode D17 in the overcharge control unit 40 connected to the battery 50. When the light 60 is turned on during the power failure and the battery voltage is lower than 10.5V, the transistor Q1 is turned off to turn on the red lamp 62. The red lamp 62 is turned off when the transistor Q1 is turned on when the battery voltage is 10.5V or more.

When the AC power is cut off in case of power failure or emergency, the relay RL2 of the charging unit 20 is operated so that the light 60 of the terminals L- and L + is turned on by the preliminary power battery 50 for a long time. When the light 60 is turned on, the relay contact rl2 is short-circuited while the relay RL1 is energized by the zener diode D18 of the over-discharge prevention circuit unit 30 and the turn-off transistor Q2. Since the connection of the battery 50 and the light 60 is short-circuited, overdischarge is prevented.

Therefore, when the discharge time elapses during a power failure and the battery voltage becomes less than 10.5 V, the zener diode D18 and the transistor Q2 are turned off, so that the light 60 is turned off and the relay contact ( The red lamp 62 is turned on by rl2. At this time, the relay RL2 is operated by the transistor Q2 through the other transistors T1 and T6.
