Abstract
A solar powered lighting arrangement (1), comprising a solar cell (2); a light source (8) adapted to be at least partly powered by electrical power derived from the solar cell (2); and a structural member (3) having a first side (4) provided with a first reflective surface (5) arranged to direct sunlight (6) towards the solar cell (2) and a second side (7) onto which the light source (8) is thermally coupled for dissipating heat generated by the light source (8) when emitting light (9). With the provision of a solar powered lighting arrangement in accordance with the present invention, the structural member may consequently function not only as a reflecting surface directing sunlight towards the solar cell, but additionally as a heat sink for the light source.
