A solid state lighting (SSL) with a solid state emitter (SSE) having thermally conductive projections extending into an air channel, and methods of making and using such SSLs. The thermally conductive projections can be fins, posts, or other structures configured to transfer heat into a fluid medium, such as air. The projections can be electrical contacts between the SSE and a power source. The air channel can be oriented generally vertically such that air in the channel warmed by the SSE flows upward through the channel.

An illustrative light fixture provides an emitter housing and a driver housing in a single fixture with an airflow channel defined between the emitter and driver housings. The airflow channel minimizes thermal conduction between the emitter and driver housings, and maximizes thermal convective cooling for at least one of the emitter housing and driver housing. The emitter housing includes vertical fins extending into the airflow chamber. The left and right sides of the emitter and driver housings define top and bottom edges that are respectively coplanar with the top and bottom edges of the vertical fins.
