Abstract: An LED lighting device (1) comprises: a base (10) having a socket connector; a housing (12) comprising a primary heat sink, the housing (12) being coupled to the base (10) and having an upper annular rim; a plate (14) having a periphery, at least the periphery of the plate being thermally coupled to the upper annular rim of the housing; at least one LED lighting source (18), the at least one LED lighting source (18) being thermally coupled to the plate; a globe (20) having a body comprising an outer surface with a light transmittable surface configured to transmit light from the LED lighting source (18) to outside the lighting device; and a secondary heat sink (22) thermally coupled to the plate (14) and the housing (12), and comprising heat conductors arranged to take the shape of the globe (20). The housing (12), plate (14)and secondary heat sink (22) cooperate to conduct heat from the at least one LED lighting source (18) to the surrounding environment.
