Zusammenfassung:A light diffusing lens for an LED street light according to the present invention comprises: an upper diffusing end (10) coupled to a lower surface of a street light body (100), and having a plurality of indentations (11) formed on an upper surface to accommodate an LED element (L) provided inside the street lamp body (100); a lower diffusing lens (20) having a plurality of refractive and reflective portions (21) for refracting or reflecting light radiated from the LED element (L) in a lower part; and a deflecting lens (30) coupled to one rear side, and reflecting the light downward, thereby enlarging the area of light initially radiated from the LED device, concentrating the light at a lower diffusion end, spreading the light transmitted through the light diffusion lens to both sides and a front side to widen the irradiated area of light, and thus increasing the lighting efficiency. 본 발명에 따른 엘이디 가로등용 광확산렌즈는 가로등 본체(100)의 하면에 결합되고, 상기 가로등본체(100)의내부에 구비된 엘이디소자(L)가 수용되도록 상부에 다수개의 요입홈(11)이 형성된 상부확산단(10)과; 하부에 상기 엘이디소자(L)에서 조사된 빛이 굴절되거나 전반사되도록 다수개의 굴절반사부(21)가 형성된 하부확산렌즈(20)와 후방일측에 결합되어 하부로 반사시키는 편향렌즈(30)로 구성되어 엘이디소자에서 최초 조사된 빛의 면적을 확대하되, 하부확산단으로 빛을 집중시키고, 광확산렌즈를 투과한 빛이 양측부와 전방으로 확산시켜 조사되는 빛의 면적으로 넓게 하여 조명효율이 증대되는 효과가 있다.
