The present invention comprises: a first Fresnel lens; a second Fresnel lens arranged to be spaced from the first Fresnel lens in parallel; and a slide motor sliding and moving the second Fresnel lens in a horizontal direction, separating a distance between the first Fresnel lens and the second Fresnel lens to vary an irradiation distance of a light source.

    본 발명은 제1프레넬 렌즈와 상기 제1프레넬 렌즈와 평행하게 이격 배치되는 제2프레넬 렌즈 및 상기 제2프레넬 렌즈를 수평방향으로 슬라이드 이동시키며, 상기 제1프레넬 렌즈와 상기 제2프레넬 렌즈 사이의 거리를 이격시켜 광원의 조사 거리를 가변시키는 슬라이드 모터를 포함한다.
