상기와 같이 구성되어 있는 본 발명의 반사갓 회전장치가 구비된 무전극 조명기기의 작용효과를 설명하면 다음과 같다. Referring to the effect of the electrodeless lighting device equipped with a reflection shade rotating device of the present invention configured as described above are as follows.

먼저, 전원이 인가되면 전원공급기(2)에서 고전압이 발생되고, 그와 같이 발생되는 고전압이 마그네트론(3)에 공급되면 마그네트론(3)에서 전자파가 생성되는데, 그와 같이 발생된 전자파는 도파관(4)을 통하여 공진기(9)의 내부로 방사되고, 그 방사되는 전자파에 의하여 전구(6)에 봉입된 물질이 방전되어 플라즈마에 의한 빛이 발생되며, 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 when a high voltage generated as such is supplied to the magnetron 3, electromagnetic waves are generated in the magnetron 3, and the generated electromagnetic wave is a waveguide ( 4) is radiated to the inside of the resonator (9), the material encapsulated in the bulb (6) is discharged by the emitted electromagnetic waves to generate light by the plasma, the generated light is reflected shade 10 Reflected by it, it is illuminated forward.

그리고, 상기와 같이 전구(6)에서 발광되는 빛을 조광하는 반사갓(10)의 조광각도를 변경하고자 할 때는, 반사갓(10)의 개구부를 조광하고자 하는 방향으로 회전시키게 되는데, 이때 라쳇트(22)가 토션스프링(23)의 스프링력에 의해 상기 기어부(21)를 따라 회전되며 탄력적으로 삽,탈되며, 소망하는 각도에 반사갓(10)이 회전을 멈추면 라쳇트(22)가 기어부(21)에 삽입된 상태로 작은 외력에는 반사갓(10)이 회전되지 않도록 고정된다.When changing the dimming angle of the reflection shade 10 for dimming the light emitted from the light bulb 6 as described above, the opening of the reflection shade 10 is rotated in the direction to be adjusted, in which case the ratchet 22 ) Is rotated along the gear portion 21 by the spring force of the torsion spring 23 and is elastically inserted and detached. When the reflection shade 10 stops rotating at a desired angle, the ratchet 22 is geared. The reflection shade 10 is fixed to the small external force while being inserted into the 21 so as not to rotate.

즉, 상기와 같이 반사갓(10)이 360도 회전가능하게 설치되어 있어서, 사용자가 조광하고자 하는 방향으로 반사갓(10)을 간단하게 회전시켜서 조광방향을 변경할 수 있으므로, 조명기기가 설치된 상태에서도 조광각도를 간편하게 변경할 수 있다.That is, since the reflection shade 10 is rotatably installed 360 degrees as described above, the direction of illumination can be changed by simply rotating the reflection shade 10 in the direction in which the user wants to adjust the illumination. Can be easily changed.

As described in detail above, the reflection shade rotating device of the electrodeless lighting device of the present invention is coupled to the reflection shade to the upper end of the main body side case, so that the reflection shade can be rotated 360 degrees and fixed to a certain angle When the user wants to change the lighting angle while the lighting device is installed, the user can easily change the lighting angle of the lighting device by rotating the reflector in a direction to be rotated and fixed at a desired angle. .
