1. A method for manufacturing a lighting device comprising an at least partly light transmitting envelope and a solid state light source, said method comprising:
arranging an at least partly light transmitting plastic material in a mold having a surface structure arranged on an inner surface portion of the mold,
blow molding the plastic material so as to form the at least partly light transmitting envelope, the surface structure being at least partly transferred to the at least partly light transmitting plastic material to form an optical structure on a portion of an outer surface of the at least partly light transmitting envelope,
removing the at least partly light transmitting envelope from said mold,
arranging the at least partly light transmitting envelope to at least partly enclose the solid state light source, and
arranging a light refracting lens in an optical path of the lighting device to focus a visual pattern in the far field, wherein said visual pattern is formed of light being diffracted by the optical structure.
