Abstract

overhead light fixture (10) includes a driver assembly (20) and a light-emitting assembly (70). The driver assembly includes a driver (50) and a housing (22). The light-emitting assembly is operably connected to the driver and configured for downward emission of light from a light source (72) of the light-emitting assembly. The light emitting assembly is detachably secured to the driver assembly. The light fixture is configured to be mounted to a canopy sheet (5) of an overhead canopy (3), with the driver assembly disposed above the canopy sheet and the light-emitting assembly disposed below the canopy sheet. The driver assembly is configured so that, when the light-emitting assembly is detached from the driver assembly, the driver is removable downwardly through the base portion and through a space previously occupied by the light emitting assembly. A bezel (80) is optionally disposed around a lens (76) of the light-emitting assembly, for aesthetic reasons and/or for controlling a degree of lateral emission of light from the light fixture.
