In accordance with the present invention, a rotary lamp optical system (1-1) applied to a vehicle (1) includes a beam pattern device (20) blocking light emitting diode (LED) light of a light source (11) on a light blocking position while transmitting the light on a light transmission position during one rotation cycle of a globular imaging optical body (30-1) or a cylindrical imaging optical body (30-2), rotating the globular imaging optical body (30-1) or the cylindrical imaging optical body (30-2), and operating the LED of the light source (11) with an LED frequency control signal (b) calculating an operation timing between the LED and a motor based on a motor control signal (a) fed back from the motor (40). Therefore, the system can generate various beam patterns without causing a change to a moving direction of an optical system by using an afterimage effect due to repetitive forward radiation of the LED light during the one rotation cycle. In particular, since the globular imaging optical body (30-1) and the cylindrical imaging optical body (30-2) are formed into a symmetrical shape, a rotation load of the motor (40) can be reduced, a light use effect using reflected light and transmitted light of a globular body (31) or a cylindrical body (34) can be improved, and also, LED control avoiding a circuit twist through position fixture can be possible due to the use of single LED.

    본 발명의 차량(1)에 적용된 회전식 램프 광학 시스템(1-1)은 구형 결상 광학체(30-1) 또는 원통형 결상 광학체(30-2)의 1 회전 사이클 동안 광원(11)의 LED(Light Emitting Diode) 빛을 빛 차단 위치에서 차단하는 반면 빛 투과 위치에서 투과시키고, 구형 결상 광학체(30-1) 또는 원통형 결상 광학체(30-2)를 회전시키며, 모터(40)에서 피드백 된 모터제어신호(a)에 기반 하여 모터와 LED 간 동작 타이밍을 연산한 LED 주파수 제어 신호(b)로 광원(11)의 LED를 작동시켜 빛 차단 위치와 차단 위치를 형성해 주는 빔 패턴 장치(20)가 포함됨으로써 1 회전 사이클 동안 LED 빛의 반복적인 전방 조사에 의한 잔상효과 활용으로 광학계의 움직임 방향 변화 없이 다양한 빔 패턴 생성이 가능하고, 특히 구형 결상 광학체(30-1) 또는 원통형 결상 광학체(30-2)의를 대칭형 형상으로 함으로써 모터(40)의 회전 부하 감소, 구형체(31) 또는 원통체(34)의 재 반사한 빛과 투과한 빛을 이용한 빛 활용 효과 향상과 함께 1개의 LED 사용으로 위치 고정에 의한 회로 꼬임 없는 LED 제어도 가능한 특징을 갖는다.
