Several outlets 1b are formed so that the compressed air can be discharged to the outside via the magnetron 3.

상기와 같이 구성되어 있는 본 발명의 전원공급기를 가지는 무전극 조명기기의 작용효과는 다음과 같다. Effects of the electrodeless lighting device having the power supply of the present invention configured as described above are as follows.

먼저, 전원이 인가되면 전원공급기(2)에서 고전압이 발생되고, 그와 같이 발생되는 고전압은 마그네트론(3)에 공급되며, 마그네트론(3)에서는 인가되는 고전압에 의하여 전자파가 생성되고, 그와 같이 발생된 전자파는 도파관(4)을 통하여 공진기(9)의 내부로 방사되고, 그 방사되는 전자파에 의하여 전구(6)에 봉입된 물질을 방전시켜서 플라즈마에 의한 빛이 발생되어 지며, 그와 같이 발생되는 빛은 반사갓(10)에 의하여 반사되면서 전방으로 비춰지게 된다.First, when power is applied, a high voltage is generated in the power supply 2, and the generated high voltage is supplied to the magnetron 3, and in the magnetron 3, electromagnetic waves are generated by the high voltage applied thereto. The generated electromagnetic waves are radiated to the inside of the resonator 9 through the waveguide 4, and the light emitted by the plasma is generated by discharging the substance encapsulated in the light bulb 6 by the radiated electromagnetic waves. The light that is being reflected by the reflector 10 is shining forward.

그리고, 상기 전원공급기(2)의 고압트랜스포머(22)는 고전압을 발생시키는 과정에서 고열이 발생되는데, 그와 같이 발생되는 열은 열전도실리콘(25)을 통하여 방열부재(26)으로 전달되고, 그와 같이 방열부재(26)로 전달된 열은 열교환면적인 넓게 형성된 방열핀(27)들을 통하여 열교환이 이루어져서 열방출이 이루어지게 된다.In addition, the high voltage transformer 22 of the power supply 2 generates high heat in the process of generating a high voltage, and the heat generated as described above is transferred to the heat dissipation member 26 through the thermal conductive silicon 25. As described above, the heat transferred to the heat dissipation member 26 is heat-exchanged through the heat dissipation fins 27 formed in the heat-exchange area so that heat is dissipated.

또한, 상기 팬 하우징(13)의 내측에 설치된 냉각팬(12)은 팬모터(11)에서 발생되는 회전력에 의해 회전되어 외부 공기를 케이스(1)의 내부로 흡입하여 케이스(1)의 내부에 설치된 각 부품이 냉각되도록 송풍되어 지는데, 이때 고압트랜스포머(22)등의 부품들은 박스체로된 방열부재(26)의 내부에 설치되어 있으므로 외기에 포함된 이물질이나 습기가 고압트랜스포머(2) 및 다른 부품들에 공급되어 쇼트가 발생될 수 있는 것이 방지되어 진다. In addition, the cooling fan 12 installed inside the fan housing 13 is rotated by the rotational force generated by the fan motor 11 to suck the outside air into the case 1 to the inside of the case 1. Each installed component is blown to cool. At this time, components such as the high-pressure transformer 22 are installed inside the heat-dissipating member 26 in a box body, so that foreign matter or moisture contained in the outside air is high-pressure transformer 2 and other components. It is prevented that a short may be generated by supplying the field.

이상에서 상세히 설명한 바와 같이, 본 발명 무전극 조명기기의 전원공급기는 발열부품인 고압트랜스포머의 일정부분을 감싸도록 열전도성 실리콘을 몰딩하고, 그 열전도성 실리콘의 외측면에 접하는 동시에 기판을 감싸도록 방열부재를 설치하여, 고전압발생과정에서 고압트랜스포머에서 발생되는 고열이 열전도성 실리콘을 통하여 방열부재로 전달되고, 방열부재로 전달된 열이 외부공기와의 열교환에 의해 열방출이 이루어진다.As described in detail above, the power supply of the electrodeless lighting device of the present invention molds the thermally conductive silicon so as to surround a portion of the high-voltage transformer, which is a heat generating component, and contacts the outer surface of the thermally conductive silicon to radiate heat to surround the substrate. By installing the member, the high heat generated in the high-voltage transformer during the high voltage generation process is transferred to the heat dissipation member through the thermally conductive silicon, the heat transferred to the heat dissipation member is heat released by heat exchange with external air.

즉, 상기와 같이 고압트랜스포머와 부품들이 설치된 기판이 방열부재로 감싸도록 설치되어 있어서, 외기에 포함된 이물질이나 습기에 의해 고압트랜스포머를 포함한 전원공급기의 각 부품이 쇼트되는 것이 방지되어 기기의 신뢰성이 향상되는 효과가 있다.In other words, as described above, the board on which the high voltage transformer and the components are installed is installed to surround the heat dissipation member, so that the parts of the power supply including the high voltage transformer are prevented from being shorted by foreign matter or moisture contained in the outside air, thereby increasing the reliability of the device. There is an effect to be improved.
