Referring to FIG. 1, an aerial lighting system 100 according to an embodiment of the present invention may include an isolation transformer 110 and a dedicated driving apparatus 120.

The isolation transformer 110 is disposed corresponding to each of the aerial lighting (lamp) 101 to oscillate (induce) a voltage.

Here, the aerial lighting 101 may be at least one of a point light source such as an incandescent lamp or a halogen lamp, or a surface light source such as a discharge lamp (e.g., a fluorescent lamp) or an LED lamp.

For example, the air conditioning system 100 may include an isolation transformer 110 corresponding to the number of the air conditioning 101 and may connect the air conditioning 101 and the isolation transformer 110, respectively.

The isolation transformer 110 is connected in series with a constant current regulator CCR which supplies a constant current to the primary winding of the isolation transformer 110 and is connected in series with the airborne equalization 101 in the secondary winding of the isolation transformer 110, Lt; / RTI > If the aerial lighting 101 is a discharge lamp, the discharge lamp may be connected in series with the secondary winding of the isolation transformer 110.

Also, the isolation transformer 110 may constitute a loop circuit through a constant current regulator and a serial cable, which supply a constant current to the aerial lighting system 100.

The dedicated drive device 120 adjusts the voltage generated by the isolation transformer 110 in consideration of the characteristics of the load (resistance) of each of the aerial equalization 101 and supplies power to each aerial equalization 101, (Not shown).

The dedicated driving apparatus 120 determines the input voltage value according to the type of the aerial lighting 101, adjusts the magnitude of the oscillated voltage according to the input voltage value, and supplies the adjusted voltage to the air lighting system 101.

For example, the dedicated drive device 120 determines the input voltage value so that when the aerial lighting 101 is a discharge lamp, it is at least boosted above the magnitude of the voltage at the oscillation time.

That is, the dedicated driving apparatus 120 can easily turn on the discharge lamp by adjusting (increasing) the magnitude of the voltage oscillated in the isolation transformer 110 according to the input voltage value and supplying it to the discharge lamp. At this time, the dedicated driving apparatus 120 may rectify the alternating voltage induced at both ends of the discharge lamp connected in series to the secondary winding of the isolation transformer 110 to a discharge voltage (DC voltage) and supply the discharge lamp.

FIG. 5 shows one example of a voltage doubler rectifying circuit for boosting a DC voltage.

The voltage multiplying rectifier is a circuit that obtains a DC output voltage close to the input AC voltage by using a rectifier and a capacitor. As shown in FIG. 5, the voltage multiplying rectifier is composed of an on-wave voltage rectification and a half- . The voltage doubler rectifier circuit can be used where the load current is relatively small because the output voltage suddenly decreases when the load current increases to some extent.

The boost section 302 is controlled within a predetermined range (for example, 2.8 A to 6.6 A) for a constant current supplied by a constant current regulator (not shown) connected in series to the primary winding of the isolation transformer 110 The DC voltage can be stepped up by adjusting the circuit constant so that the discharge lamp 304 is turned on.

The electronic circuit 303 can generate the resonance frequency necessary for driving the discharge lamp 304 by using the boosted DC voltage as the input voltage. An example of the electronic circuit 303 that generates a resonance frequency necessary for driving / lighting the discharge lamp 207 with the boosted voltage is shown in Fig.

The electronic circuit for generating the resonance frequency becomes electrically resonant at a specific frequency determined by the value of the coil and the capacitor. Such a resonance may be a condition in which the current of the RLC circuit becomes the maximum when the inductive reactance and the capacitive reactance are the same, and the specific frequency at the resonance may be the resonance frequency.

As described above, according to the embodiment of the present invention, it is possible to provide an aviation equalization system having a drive device dedicated to a discharge lamp capable of supplying an input voltage necessary for lighting a discharge lamp.

According to the embodiment, the dedicated drive device 120 can determine the input voltage value so that when the aerial lighting 101 is an LED lamp, it is at least reduced in magnitude than the magnitude of the voltage at the oscillation time. Accordingly, the aviation equalization system 100 can supply the LED lamp with a voltage adjusted (reduced in pressure) according to the input voltage value, thereby easily controlling the lighting of the LED lamp.

In addition, the dedicated driving apparatus 120 may determine the input voltage value such that the magnitude of the voltage at the oscillation time is maintained when the aerial lighting 101 is a point light source such as an incandescent lamp or a halogen lamp. In this case, the aviation equalization system 100 can be easily turned on by directly connecting the point light source through the isolation transformer.
