The present invention relates to a lighting device for guiding the takeoff and landing of a helicopter, and more specifically to a lighting device, a lighting system, and an optical system for guiding the takeoff and landing of a helicopter, such as a heliport landing area light (TLOF) and a heliport target point light (FATO). According to the present invention, an optical system for a lighting device is disclosed which comprises: an LED module (100) which includes a disc-shaped LED substrate (110), a central LED element (120) installed at the center of the LED substrate (110), and a plurality of outer LED elements (130) installed in a radial direction on a circumference having a radius set in advance from the center of the LED substrate (110); a main body (200) in which a bottom surface of the LED substrate (110) is installed spaced upward; a reflector member (300) which has a first reflection surface (311) formed on an inner circumferential surface to guide the light of the central LED element (120) laterally and a second reflection surface (312) formed on an outer circumferential surface to guide the light of the outer LED element (130) laterally, and is coupled to the LED substrate (110); and a window member (400) through which the light of the central LED element (120) and the outer LED element (130) is transmitted, and which is coupled to the main body (200) to cover an upper side of the LED substrate (110). Accordingly, it is possible to minimize power consumption and manufacturing costs, and maximize the usability of the lighting device.
본 발명은 헬리콥터 이착륙이이드용 조명장치에 관한 것으로서, 보다 상세하게는 헬리콥터의 이착륙을 가이드하기 위한 TLOF(헬기장 착륙구역등) 및 FATO(헬기장 목표지점등)와 같은 헬리콥터 이착륙 가이드용 조명장치, 조명시스템 및 광학계에 관한 것이다. 본 발명은, 원판 형상의 엘이디기판(110)과, 상기 엘이디기판(110)의 중심에 설치된 중앙엘이디소자(120)와, 상기 엘이디기판(110)의 중심으로부터 미리 설정된 반경을 가지는 원주 상에 반경방향으로 설치된 복수의 외곽엘이디소자(130)를 포함하는 엘이디모듈(100)을 포함하는 조명장치의 광학계로서, 상기 엘이디기판(110)의 저면이 상측으로 이격되어 설치되는 본체부(200)와; 상기 중앙엘이디소자(120)의 광을 측방으로 가이드하도록 내주면에 제1반사면(311)이 형성되고 상기 외곽엘이디소자(130)의 광을 측방으로 가이드하도록 외주면에 제2반사면(312)이 형성되고 상기 엘이디기판(110)에 결합되는 리플렉터부재(300)와; 상기 중앙엘이디소자(120) 및 상기 외곽엘이디소자(130)의 광이 투과되며 상기 엘이디기판(110)의 상측을 복개하도록 상기 본체부(200)에 결합되는 윈도우부재(400)를 포함하는 것을 특징으로 하는 조명장치의 광학계를 개시한다.
