LED LED lighting apparatus for road sign
The present invention relates to an LED lighting apparatus for a road sign that is located on top of the road sign to constantly provide information on the road sign, irrespective of locations to which light is irradiated, thereby improving visibility and identification of the road sign. According to the present invention, the LED lighting apparatus includes: a support fixed to a post of the road sign; and an LED lamp fixed to the support to irradiate light to the road sign and including: a hollow body; a reflector disposed inside the body and coupled to an LED module; a light collection lens coupled to the outer longitudinal periphery of the reflector to be accommodated in the body and adapted to collect the light of the LED module; a first Fresnel lens and a second Fresnel lens distant by a given distance from the light collection lens to be adjacent to each other in the axial direction of the body; and a projection lens coupled to the end periphery of the body to collect the light projected through the first Fresnel lens and the second Fresnel lens to the road sign. According to the present invention, the first Fresnel lens and the second Fresnel lens, which have convex surfaces facing each other, serve to provide the light of the LED module to the entire surface of the road sign with uniform illumination.
본 발명은 도로 표지판용 LED 조명 장치에 관한 것으로서, 도로 표지판의 지주에 고정되는 지지부; 및 지지부에 고정되어 도로 표지판을 향하여 광을 조사하는 LED 조명;을 포함하며, LED 조명은 중공의 몸체; 몸체 내측에 구비되어 LED 모듈이 결합된 반사부; 반사부의 종단 외주면을 따라 반사부에 결합되어 몸체에 수용되며, LED 모듈의 광을 집광하는 집광렌즈; 집광렌즈에서 소정거리 이격되며, 몸체의 축방향을 따라 차례로 서로 이웃하여 배치되는 제1 프레넬렌즈 및 제2 프레넬렌즈; 및 몸체의 종단에 결합되어, 제1 프레넬렌즈 및 제2 프레넬렌즈를 통해 투사된 광을 도포 표지판을 향하여 집광시키는 프로젝션 렌즈;를 구비한다. 본 발명에 의하면, 볼록한 면이 서로 마주보도록 배치된 제1 프레넬렌즈 및 제2 프레넬렌즈는 LED 모듈에 투사된 광이 표지판의 면의 형태로 빛이 모든 면에 균일한 조도로 제공되도록 할 수 있다.
