Abstract
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.

A light fixture, comprising:
- an emitter section defining a top surface, a bottom surface, and a rear surface;
- a driver section connected to the emitter section, the driver section defining a top surface, a bottom surface, a rear surface, and a front surface;
- and
- a plurality of fins connected to the emitter section, the plurality of fins defining airflow channels between the rear surface of the emitter section and the front surface of the driver section, each of the plurality of fins having a top edge and a bottom edge;
- wherein the bottom edge of at least one of the plurality of fins is coplanar with the bottom surface of the emitter section and the bottom surface of the driver section, and the bottom surface of the driver section between the front surface of the driver section and the rear surface of the driver section is planar, or;
- the top surface of the emitter section, the top surface of the driver section, and the top edge of the at least one of the plurality of fins define a planar top surface extending from the rear surface of the driver section to the front surface of the emitter section, or
- the bottom surface of the emitter section, the bottom surface of the driver section, and the bottom edge of at least one of the plurality of fins define a planar bottom surface extending from the rear surface of the driver section to the front surface of the emitter section.
