Lighting-means carrier for a strip-lighting luminaire

A strip-lighting lamp assembly comprising:

• an elongated, u-shaped strip-lighting rail (1);
• at least one light source printed circuit board (30) having light emitting diodes (33) disposed thereon;
• at least one heat sink (31) thermally connected to the light source printed circuit board (30);
• an elongated, light source mount (5) disposed within the u-shaped, strip-lighting rail (1), the light source mount including a base on which the at least one light source printed circuit board and the at least one heat sink are disposed, and opposing receiving elements on an opposite side of the base, wherein the light source printed circuit board (30) is rigidly connected to the heat sink (31) at a central area together with the elongated, light source mount (5), such that relative movement between the light source printed circuit board (30) and the heat sink (31) is substantially impossible in the central area;
• and
• at least two end connectors (20) each comprising a first pair of snap-in elements (21) and a second pair of snap-in elements (22), wherein the respective second pair of snap-in elements (22) engage with the opposing receiving elements on the elongated, light source mount (5) to attach the respective end connector (20) to the elongated light source mount;
• and
• wherein the respective first pair of snap-in elements (21) engage the light source printed circuit board (30) to connect the light source printed circuit board in a floating manner to the heat sink (31) in at least two further areas outside the central area at two opposing end regions of the printed circuit board (30), such that the light source printed circuit board (30) is disposed on the heat sink (31) so that it can move in relation to the heat sink (31) outside the central area.
