본 논문은 LED 조명의 수명 증가를 위해 전해 Capacitor가 없는 LED 구동 회로(Drive Circuit)를 P-Spice로 설계하였다. 제작 후 발생한 소비 전력 감소 문제를 Base 저항 RB 및 제너 다이오드를 이용하여 해결하였다. 제작된 LED 조명회로의 소비 전력을 측정한 결과, 소비 전력의 변화율을 기존 40%에서 15.3%로 개선하였다.
In this paper, an LED drive circuit without an electrolytic capacitor was designed with P-Spice to increase the lifespan of LED lighting. The power consumption reduction problem that occurred after design and manufacturing was solved by using a base resistor and a zener diode. As a result of measuring the power consumption of the manufactured LED lighting circuit, the change rate of power consumption was improved from 40% to 15.3%.
