Abstract:
A lighting device (1) is provided comprising a support structure (13) extending from a heat sink (10) and comprising a mounting section (14) with a central mounting face (14.2), first and second lateral mounting faces (14.1, 14.3), and at least one heat dissipation member (18a, 18b) extending from an outer face (11a.1, 11a.3) of the support structure (13) comprising a respective one of the first and the second lateral mounting faces (14.1, 14.2), the at least one first heat dissipation member (18a, 18b) comprising an inclined surface (19a, 19b) which is inclined with respect to the respective one of the first and the second lateral mounting faces (14.1, 14.3) such that a thickness of the at least one first heat dissipation member (18a, 18b) increases along a direction (40) away from the mounting section (14).
