<p>PURPOSE: An aspherical illumination lens is provided to remarkably reduce manufacturing costs by implementing various light radiation patterns with one illumination lens. CONSTITUTION: An aspherical illumination lens (20) includes a first aspherical surface unit (21) and a second aspherical surface unit (22). The first aspherical surface unit forms one side unit of the aspherical illumination lens. The first aspherical surface unit forms the light radiation pattern and includes one or more edges. The second aspherical surface unit forms other side unit of the aspherical illumination lens. The second aspherical surface unit forms a vertical surface with a progressing direction of light curved by the first aspherical surface unit. [Reference numerals] (AA) Front view; (BB) Side view</p>
