1. A submersible light fixture, comprising:
- a housing for a watertight container containing a control module; and
an LED light engine abutting a heat conducting plate, the heat conducting plate being supported by the housing, wherein the housing defines an opening substantially adjacent to the heat-conducting plate, wherein the opening is designed to be in fluid communication with a body of water when the light fixture is submerged such that the water acts as a heat sink to the LED light engine, and wherein the opening comprises a gap between the heat conducting plate and the watertight container containing the control module for the LED light engine.

Abstract
A submersible light fixture which includes a housing, and an LED light engine mounted to a heat-conducting plate, with the heat conducting plate being supported by the housing. The housing defines an opening adjacent to the heat-conducting plate, and the opening is designed to be in fluid communication with a body of water when the light fixture is submerged such that the water acts as a heat sink to the LED light engine. In one arrangement, the opening is a gap between the heat-conducting plate and a watertight container containing a control module for the LED light engine.

15. A light fixture submersible in water, the light fixture comprising:
-
a sleeve; a cap connected to the sleeve to define a watertight housing for a control module positioned therein; a heat conducting plate connected to the cap and separated therefrom by a plurality of hollow extensions to define a gap between the heat conducting plate and the cap, the gap being defined between a first surface of the heat conducting plate and an opposing surface of the cap; and an LED light engine supported by a second surface of the heat conducting plate and in thermal communication with the heat conducting plate, the first and second surfaces being on opposing sides of the heat conducting plate, wherein the gap is in fluid communication with water when the light fixture is submerged thereby allowing the water to flow through the gap. - View Dependent Claims (16, 17, 18, 19, 20)
