Abstract: Semiconductor lamp (1) having a straight, translucent tube (2) whose open end faces (3) can be closed by means of respective end caps (4), which end caps (4) are plug-connected to the tube (2), a circuit board (16) which is equipped with at least one semiconductor light source (17) is installed in the tube (2) and is in contact with at least one of the end caps (4), wherein both end caps (4) are mechanically connected to one another by means of a connection element (18) running in the tube (2), at least one of the end caps (4) is arranged such that it can be displaced longitudinally with play (d) with respect to the tube (2; 54) and thermal expansion of the connection element (18) in a longitudinal direction (L) of the tube (2) is smaller than thermal expansion of the tube (2) and wherein the connection element (18) is snap-fitted to at least one of the end caps (4). The invention can for example be used for retrofit or replacement lamps for conventional elongate lamps, e.g. fluorescent lamps and tube lamps.

Abstract: An LED light fixture includes a glass bulb. In the interior of the glass bulb is a driver module and a plurality of lighting elements. The glass bulb completely surrounds the lighting elements radially. The lighting elements are arranged radially around the driver module. The lighting elements may be LED filaments or individual light-emitting diode chips.

Abstract: A light engine for a tube lamp has a substrate defining a longitudinal direction, having at least three conductive traces extending in the longitudinal direction. At least two of the conductive traces are divided into a plurality of trace sections. The light engine further includes a plurality of semiconductor light emitting elements, each light emitting element having two electric terminals and being arranged perpendicular to the longitudinal direction and electrically connected with a first electric terminal to one of the conductive traces and with a second electric terminal to another one of the conductive traces.
