The present invention provides a lens (10) for a marine lantern (1), made to have superior visibility of the light of a light emitting diode (LED) (E) of a marine lantern (1) using the LED (E) as a light source from both long and short distances. According to the present invention, the lens comprises: an LED insertion part (20) fixed and installed to individually correspond to the outside of one LED (E) of an LED module (6), and having an opened rear side to receive the LED (E); a refractive part (30) including a refractive incident surface (31) formed on the front surface of the LED reception part (20) and a refractive surface (32) having a middle part with a larger thickness in comparison with that of the upper and the lower part in the outside of the refractive incident surface (31); a reflective part (40) including a reflective incident surface (41) formed on the upper and the lower surface of the LED reception part (20), a reflective surface (42) installed with a slope in the upper and the lower part of the reflective incident surface (41) to reflect and refract the light, and a reflective and refractive surface (43) in contact with the upper and the lower part of the refractive surface (32) of the refractive part (30) in the outside of the reflective surface (42); a combination flange part (50) projecting out from both sides of the lens (10); and a substrate reception part (60) formed with a step inside both sides of the combination flange parts (50). Thus, since the lens (10) is fixed and installed by individually corresponding to one LED (E), interference of light between the neighboring LEDs (E) while the light of each LED (E) is refracted to minimize diffusion, so visibility is maximized from both long and short distances.

    본 발명은 엘이디(E)를 광원으로 사용하는 등명기(1)의 엘이디(E) 빛을 원거리 및 근거리 모두에서 시인성을 월등하게 한 등명기(1)용 렌즈(10)를 제공코자 하는 것으로서, 본 발명은 엘이디모듈(6)에서 하나의 엘이디(E) 외측에 각각 개별적으로 대응되게 고정 설치되며, 후방이 개구되어 엘이디(E)가 내입 구성된 엘이디유입부(20)가 구비되며, 엘이디유입부(20)의 전면에 형성된 굴절입사면(31)과 굴절입사면(31)의 외측으로 중간부가 상하부에 비해 두껍게 형성된 굴절면(32)으로 이루어진 굴절부(30)가 구비되며, 엘이디유입부(20)의 상하면에 형성된 반사입사면(41)과 반사입사면(41)의 상하부에 빛을 반사시켜 굴절시키도록 경사지게 형성된 반사면(42)과 반사면(42)의 외곽에서 굴절부(30)의 굴절면(32) 상부와 하부로 각각 접하게 형성된 반사굴절면(43)으로 이루어진 반사부(40)가 구비되며, 렌즈(10)의 양측에 돌출 형성된 결합플렌지부(50)와 양측 결합플렌지부(50)의 내측에 단이 지게 형성된 기판내입부(60)가 구비된 것을 특징으로 하며, 이로 인하여 렌즈(10)가 하나의 엘이디(E)에 각각 개별적으로 대응되게 고정 설치되므로 엘이디(E) 하나하나의 빛을 굴절되게 해서 확산을 최소화시키면서 이웃하는 엘이디(E) 사이에 빛의 간섭이 일어나는 것을 최소화시켜서 원거리와 근거리 모두에서 시인성을 극대화시킬 수 있는 등 다수의 효과를 기대할 수 있다.
