The present invention relates to a lighting device (11) comprising a light emitting portion with at least two solid state light sources, SSL (18). The light emitting portion includes a first cover member (12a) with a first light source carrier (13a) and a first light transmitting portion (14), a second cover member (12b) with a second light source carrier (13b) and a second light transmitting portion (14). The first and second cover member are arranged such that a first light transmitting portion is aligned with the second SSL to allow transmission of light emitted from the second SSL through the first cover member, and a second light transmitting portion is aligned with the first SSL to allow transmission of light emitted from the first SSL through the second cover member. According to this design, light emitted from an SSL on one cover member will be transmitted through the other cover member. Dissipation of heat from each SSL may be provided in the other direction, i.e. in a direction opposite to the light emitting direction of each SSL.

The invention relates to a light emitting device, comprising at least one light source (101) and a closed container, the container comprising a first area (105) and a second area (107) that is arranged opposite to the first area (105), the closed container being filled with a heat conducting fluid (111) that is thermally coupled to an inside surface of the closed container, wherein the at least one light source (101) is arranged on an outside surface (115) of the first area of the closed container and thermally coupled to the inside surface (113) of the closed container.
