Abstract
A method is provided, wherein a lighting device () comprising an at least partly light transmitting envelope () and a solid state light source () is manufactured. The method comprises 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 and blow molding () the plastic material so as to form the envelope. During the blow molding, the surface structure is at least partly transferred to the at least partly light transmitting plastic material, thereby forming an optical structure () on a portion of an outer surface of the envelope. The envelope is then removed () from the mold and arranged () to at least partly enclose the solid state light source. The optical structure may be formed to generate a desired optical effect.
