Outdoor lighting fixture
First Claim
1. A lighting fixture, comprising:
- an enclosure comprising a cabinet having an attachment face and a cover, wherein the attachment face is disposed at a distal end of the cabinet, and wherein the cover is hingedly coupled to a bottom of the cabinet;
a heatsink coupled to the attachment face, the heatsink comprising a substantially planar mounting tray; and
a light source mounted to a bottom side of the substantially planar mounting tray,wherein the heatsink comprises a bottom edge that extends below a bottom edge of the attachment face of the cabinet of the enclosure to create a lateral space, wherein the lateral space allows water that collects on the heatsink to drain therethrough,wherein the lateral space allows air to pass therethrough, and the lateral space is disposed between the heatsink and the cover.

Abstract
A outdoor lighting fixture includes an enclosure, a heatsink, and an end-cap. The enclosure includes a cabinet and a cover that enclose control and power circuitry to provide power to illuminate a light source. The cabinet further includes an attachment face, and the extruded heatsink can be coupled to the attachment face. The extruded heatsink includes sides, a discontinuous plane of material formed with sides of the heatsink to provide a recessed mounting tray, and heat-conducting fins extending from the plane of material. The light source, which can include an LED light source, is coupled to the heatsink. The extruded heatsink can be coupled at one end to the attachment face of the cabinet at a position such that a space remains between the plane of material and a bottom edge of the attachment face, to permit water to drain from between the heat-conducting fins of the extruded heatsink.

15. A lighting fixture, comprising:
-
a cabinet comprising a plurality of sides, a top, and a bottom defining an enclosure, the cabinet comprising an attachment face that defines at least a majority of a distal side of the plurality of sides, wherein the attachment face has a first height that is less than a second height of the cabinet, wherein the first height is defined by a top edge and a bottom edge of the attachment face, and wherein the second height is defined by the top and bottom of the cabinet; a plurality of electrical components disposed within the enclosure; a heatsink coupled to the attachment face and comprising; at least a first side and opposing second side; a substantially planar mounting tray disposed between the first and second sides and integrally formed with the first and second sides; and a light module comprising an array of light emitting diode (LED) light sources coupled to the substantially planar mounting tray, wherein the heatsink is disposed such that a top surface of the substantially planar mounting tray is vertically offset below a bottom edge of the attachment face, thereby creating a lateral space, wherein the lateral space allows water that collects on the heatsink to drain therethrough, wherein the lateral space allows air to pass therethrough. - View Dependent Claims (16, 17, 18, 19)
