Abstract
A solid state lighting (SSL) device with a solid state emitter (SSE) being partially exposed in a channel loop, and methods of making and using such SSLs. The SSE can have thermally conductive projections such as fins, posts, or other structures configured to transfer heat into a fluid medium, such as a liquid coolant in the channel loop. The channel loop can include an upward channel in which the SSE is exposed to warm the coolant in the upward channel, and a downward channel through which coolant moves after being cooled by a cooling structure. The coolant in the channel loop can naturally circulate due to the heat from the SSE.
