Underwater LED lights

摘要

Underwater LED lights with enhanced cooling to allow the use of substantial numbers of high power LEDs. In all embodiments, the majority of the heat given off by the LEDs is transferred to the housing of the underwater light by heat transfer techniques other than by convection of the air or other gases within the enclosure, providing direct heat conveyance from the LEDs to or through the light enclosure walls, by conduction through a thermal conductor or by or as augmented by heat pipes to the inside wall of the enclosure or through the wall of the enclosure to the water. Various embodiments are disclosed.

主权项

1. An LED light for underwater use comprising:
an LED light assembly having a heat sink thermally accessible from the periphery of the assembly; a plate coupled to the heat sink to conduct heat from the heat sink; a housing having an open top and an outward extending flange at the open top thereof; the LED light assembly being positioned in the housing with the plate fastened to the flange at the top of the housing and extending outward beyond most of the flange; and a lens; at least one lens clamp holding the lens with respect to the plate; the lens, plate and flange assembly being sealed, whereby any other openings in the housing may be sealed to provide the LED light for underwater use.
