1. A light fixture for a light source having an emitter and driver, comprising:
- an emitter housing defining an emitter mount, the emitter coupled to the emitter mount, the emitter housing defining a rear surface, a left side, and a right side, and wherein each of the left and right side define a top edge and a bottom edge;
a driver housing, the driver coupled to the driver housing, the driver housing defining a front surface, a left side, and a right side, and wherein each of the left and right side defining a top edge and a bottom edge;
an airflow passage defined by a space between the rear surface of the emitter housing and the front surface of the driver housing; and
a first plurality of flattened fins located in the airflow passage and defining vertical oriented airflow channels, the vertical oriented airflow channels opening to a top side and a bottom side of the fixture, top and bottom edges defined by each of the first plurality of fins;
wherein the fins are oriented in a direction of airflow through the airflow channels;
and wherein the top edges of the first plurality of fins are coplanar with the top edges of the left side and the right side of the emitter housing.

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.
