Patent ID: 7534009

Claim:
A marine safety lighting device comprising: (a) a coaxially aligned lighting subassembly having: (i) an LED module including a first lens and a second lens substantially identical to the first lens, each lens having a first side and a second opposed side, wherein the first side of the first lens faces and abuts the first side of the second lens forming a lens interface, a first LED coaxially aligned with the first lens and attached to the second side of the first lens, a second LED coaxially aligned and facing the first LED, the second LED coaxially aligned with the second lens and attached to the second side of the second lens, a first thermally conductive mount attached to a side of the first LED opposed to the first lens, and a second thermally conductive mount attached to a side of the second LED opposed to the second lens, and (ii) a first heat sink having a first side and a second side, wherein the first side is mounted to a first end of the lighting subassembly and in thermal communication with the first thermally conductive mount of the LED module, (iii) a second heat sink mounted to a second end of the lighting subassembly and in thermal communication with the second thermally conductive mount of the LED module, (iv) a base unit secured to the second side of the first heat sink, and (v) a tubular member surrounding the LED module, wherein the tubular member links the first heat sink to the second heat sink and the base unit to form a mid-portion of the external surface of the lighting subassembly; (b) a power source for providing electrical power to the lighting subassembly; (c) a fresnel lens having a bull's eye, the fresnel lens encircling the lighting subassembly with the bull's eye aligned with the lens interface, whereby substantially all light emitted from the LED module passes through the tubular member first and then the bull's eye in uniformly distributed coordinates.
