본 발명은 전자파를 이용한 무전극 조명기기에 관한 것으로, 특히 마그네트론으로 공급되는 전류를 가변하여 필요에 따라 출력을 가변할 수 있는 가변출력이 가능한 무전극 조명기기에 관한 것이다.The present invention relates to an electrodeless lighting apparatus using electromagnetic waves, and more particularly, to an electrodeless lighting apparatus capable of variable output that can vary the output as needed by varying the current supplied to the magnetron.

일반적으로 무전극 조명기기(PLS : Plasma Lighting System)는 전자레인지에 주로 사용되고 있는 고주파 발진기(마그네트론)을 이용하여 그 고주파 발진기에서 발생하는 전자파가 도파관을 통해 무전극 전구를 구비한 공진기의 내부로 전달되 고, 이 공진기로 전달되는 전자파가 무전극 전구내 버퍼가스(buffer gas)를 플라즈마 상태로 만들면서 금속화합물이 빛을 연속적으로 발산하도록 함으로써 전극 없이도 뛰어난 광량의 빛을 제공할 수 있는 기기이다.In general, a PLS (Plasma Lighting System) uses a high frequency oscillator (magnetron) mainly used in a microwave oven, and electromagnetic waves generated from the high frequency oscillator are transmitted to the inside of the resonator including the electrodeless bulb through the waveguide. In addition, the electromagnetic wave transmitted to the resonator causes the metal compound to emit light continuously while making the buffer gas in the electrodeless bulb into the plasma state, thereby providing excellent light quantity without the electrode.

이러한 무전극 조명기기는 대체로 마그네트론의 출력이 고정적이어서 전원을 공급하면 그 마그네트론에 설정되어 있는 정도의 출력만큼 전자파를 생성하면서 항상 동일한 밝기의 조명강도를 제공하게 된다.In general, such an electrodeless lighting device has a fixed output of the magnetron, and when the power is supplied, it generates the electromagnetic waves as much as the output set in the magnetron and always provides the same brightness intensity.

그러나, 상기와 같은 종래 무전극 조명기기에 있어서는, 전술한 바와 같이 사용환경 또는 사용자의 요구와는 관계없이 항상 동일한 밝기의 조명강도를 발생함에 따라 에너지 효율이 저하되는 문제점이 있었다.However, in the conventional electrodeless lighting apparatus as described above, there is a problem that the energy efficiency is lowered as the illumination intensity of the same brightness is always generated regardless of the use environment or the user's request as described above.

The light-emitting material encapsulated by the plasma-forming electrodeless bulb 5 and the waveguide 4 and the waveguide 4 and the electrodeless bulb 5 are pressed and fixed to the front of the waveguide at a predetermined resonance frequency. While resonating, the electromagnetic wave is confined while the resonator 6 passes the light emitted from the electrodeless bulb 5, and the reflection accommodates the resonator 6 so as to intensively reflect light generated from the electrodeless bulb.

즉, 제어부의 지령에 따라 마그네트론(2)은 고압에 의해 발진하면서 매우 높은 주파수를 갖는 전자파를 생성하고, 이 전자파는 도파관(4)을 통해 공진기(6) 내부로 방사하면서 무전극 전구(5) 내에 봉입된 불활성가스를 여기(exiting)시킨다. 이 과정에서 발광물질이 지속적으로 플라즈마화 하면서 고유한 방출 스펙트럼을 가지는 빛을 발생하고, 이 빛은 반사갓(7)과 유전체거울(8)에 의해 전방으로 반사되면서 공간을 밝힌다.That is, the magnetron 2 generates an electromagnetic wave having a very high frequency while oscillating by a high pressure according to the command of the controller, and the electromagnetic wave 5 radiates into the resonator 6 through the waveguide 4. The inert gas enclosed therein is excited. In this process, the light emitting material continuously emits light having a unique emission spectrum, and the light is reflected forward by the reflection shade 7 and the dielectric mirror 8 to illuminate the space.

이렇게 하여, 주변의 밝기나 사용자의 요구에 따라 조명기기의 조명강도를 사용자가 임의로 적절하게 조절할 수 있어 불필요한 에너지의 낭비를 절감할 수 있다.In this way, the user can arbitrarily appropriately adjust the lighting intensity of the lighting device according to the brightness of the surroundings or the user's request, it is possible to reduce unnecessary energy waste.

본 발명에 의한 가변출력이 가능한 무전극 조명기기는, 사용환경이나 사용자의 요구에 따라 마그네트론에 흐르는 전류량을 적절하게 가감하여 조명강도를 조절할 수 있도록 함으로써, 주변의 조명환경에 따라 광량을 조절할 수 있고 이를 통해 필요 이상의 빛을 발생시켜 불필요한 에너지의 낭비가 야기될 수 있는 것을 미연에 방지할 수 있다.According to the present invention, the electrodeless lighting apparatus capable of variable output can adjust the light intensity by appropriately adding or subtracting the amount of current flowing through the magnetron according to the use environment or the user's request, thereby adjusting the amount of light according to the surrounding lighting environment.
