Generally, fluorescent lamps are mainly used for various types of buildings and public facilities such as residential and office buildings. When such fluorescent lamps are used as illumination lamps, external power sources are directly connected. Therefore, power consumption is high, There is a problem that it is economically disadvantageous.

On the other hand, in an area where electric power can not be smoothly supplied through an electric wire, such as an island area or a mountain area far from the land, electric power is generated to generate electric energy, However, in this case also, when a fluorescent lamp is applied to an illumination lamp, there is a problem in that the battery is frequently consumed because the battery is frequently replaced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a power supply system for a power plant, A power supply of new LED illumination lamp which can reduce the consumption of electric energy by installing LED lighting instead of conventional fluorescent lamp in various buildings or public facilities by enabling power supply to LED lighting through battery System.

Another object of the present invention is to prevent the deterioration of the life of the battery by preventing the deterioration of the battery caused by the repeated charging / discharging operation by connecting a separate restoration charger to the capacitor, And to provide a power supply system of a new LED illumination lamp.

In order to achieve the above object, the present invention provides a lighting system comprising: an LED lighting unit installed in a residential and office building or a public facility; A battery for charging a commercial power source applied from the outside; An inverter for stabilizing an output voltage with respect to an input variation or a load variation of a current applied from the battery to the LED lamp in a state of being electrically connected to the LED lamp and the battery and protecting the inverter from an obstacle such as an overcurrent; The battery is supplied with external power in the state of being electrically connected to the battery and the external power source, and a high-quality power source is implemented to charge the battery. At the same time, it prevents the sulphate fixing phenomenon on the electrode plate constituting the battery, And a restoration charger for recovering the performance of the battery by removing sulphate fixed to the electrode plate.

The present invention can be applied not only to areas where power can not be smoothly supplied through electric wires such as island areas and mountain hills far from the land, but also to various buildings and public facilities in place of conventional fluorescent lamps Since the power supply for the LED light is provided through the battery, the consumption of electric energy is greatly reduced, which is economically advantageous.

In addition, since a separate restoration charger is applied in the present invention, it is possible to prevent the deterioration of the capacity of the battery caused by the charging / discharging operation repeatedly over a long period of time, thereby preventing the life of the battery from being shortened, It is possible to prevent the environmental pollution caused by the environment.

FIG. 1 is a block diagram showing a power supply system of an LED illumination or the like according to the present invention.

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

Referring to FIG. 1, a power supply system 10 of an LED lighting or the like according to the present invention is for stably supplying good quality power to an LED illumination lamp 12 installed in a residential, office building, or public facility.

In the present invention, a battery 14 for charging a commercial power source applied from the outside is installed, and between the LED illumination lamp 12 and the battery 14, a current of a current applied from the battery 14 to the LED illumination lamp 12 The inverter 16, which stabilizes the output voltage with respect to the input fluctuation and the load fluctuation, and which protects the inverter from an obstacle such as an overcurrent, is electrically connected.

A high-quality power is supplied to the battery 14 by supplying external power to the battery 14 and the external power source 20, and at the same time, the battery 14 is fixed to the electrode plate constituting the battery 14 And a restoration charger 18 for recovering the performance of the battery 14 by removing the sulfate which is fixed to the electrode plate of the storage battery 14 is electrically connected.

In the present invention, the external power source 20 is installed in an area where power supplied from the power plant is not supplied due to geographical conditions as well as power supplied from the power plant, and is operated using fuel, Various types of generators 20 for generating energy may be used.

The operation of the present invention is as follows.

Referring to FIG. 1, an external power source 20 supplied from a power source or an external generator is applied to a battery through a restoration charger 18, and the battery 14 is charged with a current.

The current charged in the battery 14 is applied to the LED illumination light 12 via the inverter 16. The inverter 16 detects an input variation of the current applied from the battery 14 to the LED illumination light 12 It stabilizes the output voltage against the load fluctuation and protects it from obstacles such as overcurrent.

Meanwhile, the restoration charger 18 receives power from the external power source 20 and realizes a high-quality power source to charge the battery 14 and regenerates the damaged battery 14 by repeated charging and discharging .

The battery 14 is composed of a positive electrode plate (PbO ₂ ), a negative electrode plate (Pb), and an electrolyte (H ₂ SO ₄ ), and converts chemical energy contained in the activating material into electrical energy using an electrochemical action.

The discharge reaction in the battery 14 is a process in which lead in the anode is lead dioxide and lead in the cathode is lead sulfate as shown in the following equation.

Discharge reaction formula: PbO₂ + Pb + 2HSO₄ + 2H → 2PbSO₄ + 2H₂O

The charging reaction in the battery 14 is a process in which lead sulfate is returned to the positive electrode and lead dioxide is returned to the negative electrode as shown in the following equation.

Charging _{scheme: 2PbSO₄ + 2H 2 O → Pb} + PbO₂ + 2H 2 SO₄

The reaction sheet is a cathode: PbSO₄ + 2e → Pb + SO4², and a cathode: PbSO₄ + 2H₂O → PbO₂ + 4H + SO4 + 2e.

When the battery 14 is discharged, the sulfate (SO ₄ ) bonds with the electrode to generate water, thereby lowering the specific gravity. When the battery 14 is charged, the combined sulfate returns to the electrolyte and the specific gravity is increased.

However, during charging and discharging repeatedly in the battery, the sulfate which is bonded to the electrode during the discharging process remains attached to the electrode without being dropped even during charging and discharging, thereby causing a sulfation phenomenon to form an insulating layer.

Accordingly, when the number of times of charging and discharging occurs repeatedly in the battery 14, the sulfate is excessively accumulated on the surface of the electrode, the passage of the chemical / electrical reaction is blocked, the electric energy storage capacity is lowered, If the battery 14 is continuously used for about 400 cycles without regenerating the battery 14 in such a state, the voltage reaches the discharge end voltage and can no longer be used, resulting in disposal.

The restoration charger 18 applied to the present invention continuously supplies regeneration pulses of 20 to 30 KHz to the positive electrode and negative electrode of the battery 14 to remove sulphate which is fixed to the electrode plate of the battery 14, And a regenerative pulse that periodically discharges the battery, thereby regenerating the battery having a relatively low performance.
