Disclosed is an invention related to a diffusion lens. The disclosed diffusion lens comprises: a first lens unit which allows light of a light source to be refracted and irradiated to an outside; and a second lens unit provided around a circumference of the first lens unit, allowing the refracted light from the first lens unit to be irradiated to the outside by continuously refracting the refracted light from the first lens unit, thereby widening a diffusion rage of light, reducing optical noise, and providing a diffusion lens having cheaper manufacturing costs. |
