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.

Method for manufacturing a lighting device

A lighting device () and a method of manufacturing a lighting device, wherein the lighting device comprises at least one light source () arranged to generate light. The lighting device further comprises a light-transmissive envelope () enclosing the at least one light source and being arranged to transmit the light generated from the light source. The lighting device further comprises a driver unit () arranged for electrical supply to the at least one light source, the driver unit comprising a primary driver circuit () connectable to an electric energy source, at least one secondary driver circuit () connected to the at least one light source, and a transformer () arranged to transfer electrical energy between the primary driver circuit and the at least one secondary driver circuit, wherein at least the transformer and the at least one secondary driver circuit driver unit are arranged within the envelope.

Lighting device comprising a driver unit and method of manufacturing the same

A lighting device () is disclosed, comprising an at least partly light transmitting envelope () arranged to at least partly enclose a light source (). The envelope comprises a portion () that is elastic such that its extension and orientation relative to a nominal optical axis of a base () of the lighting device is adjustable so as to allow for light output from the lighting device to be modified. A method for manufacturing such lighting device is also disclosed.
