Zusammenfassung:In the present invention, a lens device for an ultra-thin and high-magnification concentrating solar module is disclosed. The lens device for ultra-thin and high-magnification concentrating solar modules comprises: a Fresnel lens unit (100) having a predetermined condensing focus size and is formed to be convex downward; and a total reflection (TIR) lens unit (200) formed by a plurality of total reflection lenses surrounding the Fresnel unit (100) in a concentric circle and having the condensing focus size. The present invention can increase the deflection angle of incident light by the principle of total internal reflection and can apply a primary optic element (POE) with a thickness of about 50mm, which allows precision injection molding of optical plastic. 본 발명에서는 초박형 고배율 집광형 태양광 모듈용 렌즈 장치가 개시된다. 초박형 고배율 집광형 태양광 모듈용 렌즈 장치는, 소정의 집광 초점 크기를 가지며, 하부로 볼록하게 형성되는 프레넬 렌즈부(100); 다수개의 전반사 렌즈가 상기 프레넬 렌즈부(100)를 동심원 형태로 둘러싸도록 형성되며, 상기 집광 초점 크기를 가지도록 형성되는 전반사(TIR) 렌즈부(200)를 포함한다. 이러한 본 발명은 내부전반사의 원리에 의해서 입사광의 편향각을 높일 수 있고, Optical Plastic 정밀 사출성형이 가능한 두께 50mm 수준의 Primary Optic Element (POE)를 적용할 수 있다.
