Hereinafter, a power supply circuit of a ship LED illumination according to an embodiment of the present invention will be described.

In order to develop an 80W-class power supply circuit used in shipboard LED lighting of the present invention, it is necessary to control the output voltage and current corresponding to the LED drive voltage and to protect the power supply circuit 15KV / 7.5KA protection circuit should be constructed.

For this purpose, the present invention applies a one-stage method to achieve high efficiency in an 80 W power supply circuit, and designed by using a flyback method to reduce the size of a circuit. In addition, the AC stabilization module rectifies the AC power supply and eliminates noise. By designing to generate a constant output by adopting the current mode method through the PWM control, the overvoltage, the overcurrent, and the surge ) Designed to protect the power supply and LED module.

FIG. 3 is an internal block diagram of a power supply circuit of a ship LED illumination according to an embodiment of the present invention, FIG. 4 is an internal configuration diagram of the AC stabilization module shown in FIG. 3, 15KV / 7.5KA class overvoltage, overcurrent and surge protection module according to Fig. FIG. 6 is a circuit diagram of an 80 W power supply SMPS according to an embodiment of the present invention, and FIG. 7 is an internal configuration diagram of the DC stabilization module shown in FIG.

3, the power supply circuit 200 of the present invention includes an AC stabilization module 210 and an AC stabilization module 210 for transmitting AC power input through a commercial power supply to the power supply 220 And a DC stabilization module 230 for supplying a driving power output from the power supply unit 220 to the LED module 500. The power supply unit 220 includes a DC power supply 220 and a DC stabilization module 230,

First, the AC stabilization module 210 protects the power supply circuit 200 and the LED module 500 by attenuating and absorbing an instantaneous overcurrent, overvoltage, or surge current generated from the AC power applied from the commercial power supply, . 4, the AC stabilization module 210 includes a current limiting unit 212 for attenuating overvoltage and surge, a current sensing unit 214 for sensing an input current, a current sensing unit 214, And a current control unit 216 for controlling the current of the AC power according to a detection signal from the AC power source.

The current limiter 212 includes 14 overvoltage protection surge absorbers Ab1 to Ab14 (Surge Absorber) arranged in parallel to the AC power sources AC_L and AC_N input as shown in FIG. 5, And varistors (MOV1 to MOV14, Varistor) for overvoltage protection, which are connected in series to an AC power source that is connected in series.

The surge absorbers Ab1 to Ab14 attenuate the initial instantaneous overvoltage or surge current in the instantaneous overvoltage or surge current applied from the power source and the varistors MOV1 to MOV14 attenuate the instantaneous overvoltage or surge current from the overvoltage or surge current applied from the power source, It absorbs current and protects circuit of power supply circuit.

The surge current is a very short time, but the waveform and amplitude vary according to the flowing time. At first, the waveform is high and the amplitude is small. However, as time passes, the waveform becomes low and the amplitude becomes large. Therefore, the surge absorbers Ab1 to Ab14 and the varistors MOV1 to MOV14 are connected in series to absorb the surge currents of both the surge absorbers Ab1 to Ab14 and the varistors MOV1 to MOV14. That is, the surge current Ab1 to Ab14 attenuates in the initial surge current, that is, the surge current having a high peak and a short cycle, and the surge current in which the latter peak is low and the cycle is long, MOV 14 absorbs and absorbs the surge current input to the AC stabilization module 210 completely.

The current sensing unit 216 senses the current of the AC power input to the AC stabilization module 210 and transmits a sensing signal to the current control unit 214. In particular, when an overcurrent is input from a commercial power source due to a natural phenomenon such as a lightning strike, a lightning strike, an external electrical operation, unstable power supply, or the like, the current sensing unit 216 senses an input of an overcurrent, (214).

The current control unit 214 controls the current value of the AC power outputted to the power supply unit 220 based on the sensing signal input from the current sensing unit 216. For example, when the current detection unit 216 detects that an overcurrent is input from the commercial power source, the current control unit 214 adjusts or limits the input overcurrent to a rated current and outputs the overcurrent to the power supply unit 220 .

5 to 6, the current controller 214 is disposed at the rear of the current limiter 212 and detects the AC currents AC_L and AC_N applied from the current limiter 212. The current limiters 212, The voltage is lowered and finely adjusted to supply the power supply 220 with current so as to meet the appropriate load capacity. To this end, the current controller 214 includes a plurality of capacitors C1 and C2 configured in parallel.

The current control unit 214 is a part for lowering the AC input voltage with the capacitor as the main axis. The current control unit 214 is capable of adjusting a voltage value that decreases according to the capacitance of the capacitor. The current control unit 214 is composed of a plurality of capacitors such as a capacitor. The alternating current applied to the current control unit 214 is stored in the capacitor C1 and charged. The excess current remaining in the capacitor C1 is stored in the capacitor C2 and charged. That is, when the capacitor of the current control unit is Cn, the capacitor C1, the capacitor C2, and the capacitor Cn are sequentially charged in that order. When the charged alternating current becomes a certain value or more, And the electric current is supplied to the power supply unit 220 connected to the rear of the AC stabilization module 210.

Accordingly, the AC stabilization module 210 rectifies the AC power input from the commercial power supply, removes the noise, and controls the surge caused by natural phenomena such as lightning, lightning, and the overvoltage caused by external electrical work or unstable power supply And the overcurrent, the power supply circuit can be stably protected and the rated life can be maintained. In addition, the circuit is controlled in a current mode to generate a constant output to the power supply 220.

The switching power supply SMPS supplies a commercial power source (for example, 220 V or 110 V AC power) supplied from the AC stabilization module 210 to a driving power source (not shown) for driving the LED of the LED module 500 For example, a DC power supply). A circuit diagram of an 80 W power supply (SMPS) according to an embodiment of the present invention is shown in FIG.

As shown in FIG. 6, the 80 W power supply of the present invention is designed as a flyback converter. The flyback converter has a smaller number of elements than other converters, it is easy to vary the output voltage by changing the winding ratio of the transformer, and the power supply and the load are electrically insulated by the transformer. In addition, a one-stage PFC circuit with its own power factor correction and constant voltage output characteristics was included for 90% or more power factor. In addition, the LC resonance filter was applied to greatly reduce the ripple component on the output side.

The DC stabilization module 230 transmits the DC driving power output from the power supply unit 220 to the LED module 500. The DC stabilization module 230 may include a driving power sensing unit 232 and a driving power control unit 234, as shown in FIG. The driving power sensing unit 232 is formed to correspond to each of the output terminals connected to the plurality of driving power supply lines, detects the connection state with the driving power supply lines, and transmits a sensing signal to the driving power control unit 234 do. The driving power control unit 234 controls whether or not the driving power is output according to the sensing signal transmitted from the driving power sensing unit 232. The driving power control unit 234 stabilizes the direct current level of the power output while preventing the overvoltage or the overcurrent of the direct current applied from the power supply unit 220. The DC stabilization module 230 may be included in the power supply 220.
