The power is charged in the charging capacitor CL by the DC power supply DC of the converter 20, and the power charged in the charging capacitor CL is supplied to the light emitting device 50 when the power supply is cut off. The charging unit 40 is provided so that the charging capacitor CL is provided, the light emitting device 50 is preferably provided with a high brightness light emitting diode (LED).

Next, the detailed circuit structure of each structure is demonstrated with reference to FIG.

The protection unit 10 is connected to a fuse and a first capacitor C1 for protecting a circuit by overcurrent in one line of the AC power supply terminal, and the first resistor R1 and the second line in the other line. The resistor R2 is connected.

The conversion unit 20 receives AC power (AC) 220V and performs a primary conversion into a 12V DC power supply, and converts the first converted DC power of 12V to 5V power required for charging. do. Accordingly, the conversion unit 20 includes a bridge diode 22 for converting AC power to DC power, and a smoothing capacitor C2 that smoothes harmonic noise included in the DC power output by the bridge diode 22. ) And a constant voltage diode D1. In addition, a power conversion IC 24 for converting the 12V DC power supply into a 5V power source required for charging is provided. In the present embodiment, the IC for power conversion is an 'IC7808' device.

The switching unit 30 supplies the DC power converted by the conversion unit 20 to the charging capacitor CL of the charging unit 40 when the AC power is supplied, or cuts off the supply of the AC power. The switching module 31 is provided to form a charging path or a supply path to supply the power charged in the charging capacitor CL of the charging unit 40 to the light emitting device (50). The switching module 31 is provided with a coil through which a current flows and two switching terminals 32 and 34 that are turned on and off by the current supply. The switching terminals 32 and 34 form a charging path for charging the 5V power converted by the power conversion IC 24 into the charging capacitor CL, and the AC power supply. The second switching terminal 34 forms a supply path so that the power charged in the charging capacitor CL is supplied to the light emitting device 50 at the time of interruption. Each of the switching terminals 32 and 34 is provided with a total of three contacts, and any one of the upper contacts c provided on the secondary side according to the operation of the switching member connected to the primary side contacts a and a '. (c ') or the bottom contact (b) (b') is connected to / open structure. That is, when the switching member is connected to any one contact of the secondary side, the charging path or the supply path is formed. In this embodiment, when the switching member of the first switching terminal 32 and the second switching terminal 34 is connected to the lower contact (b) (b ') of the secondary side at the same time a charging path is formed, When connected to the upper contact (c) (c ') at the same time the supply path is formed.

A large capacity charging capacitor CL is connected to the charging unit 40. The charging capacitor CL is currently provided with a capacity of 1.5F / DC 5.5V, and a charging capacitor CL having an appropriate capacity is provided according to a place to which the power supply of the present invention is applied and a time required for lighting. . For example, the power supply device should have a capacity to sufficiently light the light emitting device 50 by the charging power of the charging capacitor CL during the time required for the emergency generator to operate normally in the event of a power failure. Of course, the capacitance is also related to the efficiency of the light emitting device 50. In the present exemplary embodiment, only one charging capacitor CL is provided. However, in order to charge a high capacity, the charging capacitor CL may be configured in series, in parallel, or in series / parallel to extend the lighting time.

Next, a control method of the rechargeable power supply device configured as described above will be described. This power supply device can be used as an emergency power source, it will be described by way of example used in place of the emergency power supply using a conventional rechargeable battery.

First, 220V AC power is normally supplied in the state where the power supply device is installed (step 10). In this case, when an abnormality of the AC power occurs, the fuse of the protection unit 10 provided at the front end of the power supply device is short-circuited to cut off the power supply.

Once 220V AC power is supplied and supplied to the conversion unit 20, in the twelfth step, the bridge diode 22, which is the rectifying element, is converted into a pulse current similar to that of the DC power source and rippled by the smoothing capacitor C2. ) Is converted to direct current power source. The smoothly rectified DC power source is stabilized to a constant output power source by a constant voltage diode (D1), thereby converting the primary power source to 12V. The primary converted 12V power is again provided to the power conversion IC of the conversion unit to secondary conversion to a 5V DC power supply which is a power required for charging.

The secondary converted 5V DC power supply is a state in which the switching member of the first switching terminal 32 is connected to the lower contact b of the secondary side in contact with the charging capacitor CL of the charging unit 40. Since charging paths connected to the +) and (-) terminals are formed, charging is performed due to the normal supply of power (step 14) (step 16). In this case, whether the charging capacitor CL is charged can be checked by a display device (not shown) connected in parallel with the charging capacitor CL. That is, the display device may be provided with a light emitting diode or the like, and the LED is turned on when the charging capacitor CL is fully charged.

Next, the AC power is cut off while the charging capacitor CL is completely charged.

That is, when a power failure or the like is interrupted in the eighteenth step, the supply of the AC power is cut off, and thus the power from the converter 20 is not output, and thus a change occurs in the current value flowing through the coil of the switching module 31. . In other words, when a current flows through the coil, a charging path is formed in a state in which the switching member is connected to all of the lower contacts b and b '. However, if no current flows through the coil, each of the switching members of the first and second switching terminals 32 and 34 connected to the lower contacts b and b 'may have both the upper contact c and the switching member. c ').

Then, the charging path formed by the first switching terminal 32 is opened so that charging can no longer be performed, and the switching member of the second switching terminal 34 is connected to the upper contact c '. A supply path for supplying power from the positive terminal of the charging capacitor CL is formed (step 20). In other words, the positive terminal of the charging capacitor CL is connected to the light emitting device 50, and the negative terminal is continuously connected to the output terminal of the power conversion IC 24. Therefore, as long as the supply of the AC power is cut off, the charging path is immediately closed and the supply path is formed, and the power charged in the charging capacitor CL is supplied to the light emitting device 50 in the twenty-second step. Then, the light emitting device 50 is turned on in the twenty-fourth step. The light emitting device 50 is turned on only as much as the capacity charged in the charging capacitor CL.

On the other hand, the charging capacitor (CL) applied to the present embodiment can overcome the disadvantages of the conventional rechargeable battery because it is characterized in that the charging is made rapidly and is operated to supply the charged power when the AC power is cut off. Therefore, it can apply to the place which emergency power supply needs fully.

As such, the rechargeable power supply device having the charging capacitor CL may be configured to be portable. Therefore, the plug of the power supply unit can be connected to the general plug terminal to easily determine the charging state of the charging capacitor CL according to whether the light emitting device 50 is turned on. According to the lighting of (50) it can be conveniently known whether or not normal operation.

That is, FIG. 4 is a view illustrating an embodiment in which such a rechargeable power supply device is connected to a plug terminal, and the rechargeable power supply device may be used in a place where emergency lighting is required. At this time, the charging capacitor CL of the rechargeable power supply device should be charged.

It will be apparent that other embodiments may be modified and equivalent. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, the rechargeable power supply device and the control method thereof have the following effects.

First, since the lamp is turned on when a power failure is applied by applying a capacitor that is a device that accurately performs charging and discharging, the conventional battery may overcome the disadvantage of shortening the lifespan due to leakage of the charging liquid.

In addition, since it can be configured to be portable, it is possible to easily check the charging state of the charging capacitor provided in the power supply device and the operating state of the power supply device.

In addition, because it is portable and easy to install, it can be appropriately provided at a location where emergency power is needed, and there is also an effect of low maintenance cost.
