    Abstract: A method for designing a lens of a lighting device having a first spherical surface refracting light generated from an LED device that is a light source and a second spherical surface refracting the light passing through the first spherical surface includes determining an irradiation surface that is an area onto which light passing through the second spherical surface is irradiated, forming a reference circle disposed within the irradiation surface; designing a free curved surface of the first spherical surface by using light emitted from the LED device as an input direction vector and a coordinate within the reference circle as an output direction vector to calculate normal vectors, and designing a free curved surface of the second spherical surface by using light refracted by the first spherical surface as an input direction vector and a coordinate within the irradiation surface as an output direction vector to calculate normal vectors.
