There is provided a carrier () for solid-state lighting devices (). The carrier () is intended to be arranged in a light bulb and is formed from one single flat and formable substrate (), which has been bent to a generally tube-shaped form. The carrier () includes: an annular mounting portion () for mounting the carrier () inside the light bulb; and two or more strips () extending generally parallel to each other from the annular mounting portion () and being separated from each other in a tangential direction of the annular mounting portion (). Each strip () has one or more electrically conducting paths () and a solid-state lighting device () mounted thereon. There is also provided a method for producing a tube-shaped carrier (). The strips are easy to shape by bending, twisting and/or folding, resulting in a significant freedom in the positioning of the SSL devices.

Carrier for solid-state lighting devices intended for a light bulb

A lighting module () is disclosed, comprising a light-transmissive, elongated member () with a light-guiding region () within the elongated member (). The elongated member () may be configured such that the light-guiding region () permits passage of fluid through the elongated member (), possibly between a first end () and a second end () thereof. A plurality of light-emitting elements () are coupled to the elongated member () within the elongated member () and such that the optical axis of at least one light-emitting element is non-perpendicular with respect to a longitudinal axis (LA) of the lighting module (). A lighting device () comprising the lighting module () is also disclosed.

Lighting module and lighting device comprising the lighting module

There is provided a light bulb () which comprises: a cap () for mechanically and electrically connecting the light bulb () to a lamp socket; a light-transmissive envelope (); a stem () arranged inside the envelope (), the stem () including a base portion () proximal to the cap (); and at least one carrier () and one or more solid-state lighting devices () mounted on the at least one carrier () inside the envelope (). The at least one carrier () is supported by the base portion () of the stem (). There is also provided a method for producing a light bulb ().
