Abstract

Use of UV gel for nail management have been increasing gradually. In order to develop an UV lamp necessary to UV gel, in this study, we was designed circuits of the UV-LED lamp. Power supply part that supplies constant power to the several UV-LEDs, was designed the circuit with the method of DC-DC converter. Taking into account the direction of the thumb nail and the position of the little finger nail, it was placed UV-LEDs. Input power of the power supply part was used as a battery voltage of 3.8[V]. The output voltage of the power supply part was appeared in approximately 3.1[V]. And in order to examine the state of change of the output voltage according to the amount of current consumption of UV-LEDs, after inserting of load resister, the output voltage was more than about 3.0[V] in the simulation results of the power supply part while changing the resistance value.

손발톱 관리를 위해 UV 젤의 이용이 점차 증가하고 있다. UV 젤에 필요한 UV 램프를 개발하기 위해 본 연구에서는 UV LED 램프 구성 회로를 설계하였다. 여러 개의 UV LED들에 일정한 전원을 공급하는 전원부는 DC-DC 컨버터 방식의 회로로 설계를 하였다. 그리고 엄지손톱의 방향과 소지손톱의 위치를 고려하여 UV LED들을 배치하였다. 전원부의 입력전원은 3.8[V]의 전지전압을 사용하였다. 전원부의 출력전압은 약 3.1[V]로 나타났으며, UV LED들이 소모하는 전류량에 따른 출력전압의 변화 상태를 알아보기 위해 부하저항을 삽입한 후 부하저항을 변화시켜 가면서 시뮬레이션 한 결과에서도 출력전압은 약 3.0[V] 이상으로 나타났다.
