Abstract (en)
A lighting device (1, 100, 101) comprising a puck assembly (2) comprising a plurality of LEDs (11), and a cover element comprising an outer shell element (4) adapted for forming a light exit surface of the lighting device and an inner shell element (3), the outer shell element and the inner shell element forming together a hermetically sealed gas chamber (5), the hermetically sealed gas chamber being filled with substantially one single gas adapted for functioning as a heat transferring medium for transferring heat from the puck assembly towards the outer shell element, and the inner shell element forming a cavity (31) adapted for accommodating the puck assembly at least partially in such a way that the puck assembly is arranged outside the hermetically sealed gas chamber in a heat transferring relationship with the inner shell element and thereby with the substantially one single gas provided in the hermetically sealed gas chamber.
