Abstract
본 발명은 인버터 스탠드의 조도제어방법에 관한 것으로, 조도조절버튼(21)에 의해 설정된 조도에 따른 발진 주파수를 발진부(25)에서 발생하여 그 발진주파수를 근거로 램프(27)를 통해 조사되는 광의 조도가 조절되는 인버터 스탠드에 있어서, 포토다이오드(PD)를 통해 광량을 수광하여 주변조도를 감지하는 단계와, 상기 포토다이오드(PD)에 의해 감지된 주변조도에 반응하여 발생되어진 발진주파수(f1)를 상기 조도조절버튼(21)에 의해 설정되어진 기준발진주파수(f2)와 비교하는 단계, 비교되어진 비교치(f1-f2)에 기초하여 발진주파수가 보정되도록 발진부(25)를 제어하는 단계 및, 상기 발진부(25)로부터 보정된 발진주파수가 발생되는 단계로 이루어진 것을 특징으로 한다The present invention relates to an illuminance control method for an inverter stand, in which an oscillation frequency corresponding to an illuminance set by an illuminance adjustment button (21) is generated in an oscillation section (25) A method of driving an inverter stand, the method comprising the steps of: receiving an amount of light through a photodiode (PD) to detect ambient illuminance; detecting an oscillation frequency (f1) generated in response to ambient illuminance detected by the photodiode (PD) Controlling the oscillation unit 25 so that the oscillation frequency is corrected on the basis of the compared values f1 to f2 that are compared with the reference oscillation frequency f2 set by the illumination adjustment button 21, And the corrected oscillation frequency is generated from the oscillation unit 25
