Abstract
Official abstract text for this publication.
Lighting devices using selectively permeable barrier elements, graphite sheet materials, and/or browning agent destroyers/sequestering agents are disclosed. In one embodiment a lighting device may include a body or housing with a selectively permeable barrier element, such as a silicone membrane or o-ring to allow diffusion of contaminants from one or more interior volumes to the exterior environment. Contaminants may be mitigated through use of a sequestering agent/browning agent destroyer. Heat conduction between elements of the housing, such as to aid removal of heat generated from a lighting element such as an LED, may be improved through use of graphite materials, such as PGS sheets between housing elements.
First claim
Opening claim text (preview).
We claim: 1 . An underwater light for deep ocean use, comprising: a housing adapted to withstand deep ocean pressures, the housing enclosing a plurality of interior volumes; an electronic circuit element including one or more light emitting diodes (LEDs) within one or more of the plurality of volumes; and a selectively permeable barrier element disposed in the housing having a first area exposed to one of the interior volumes and a second area exposed to a gas or liquid volume exterior to the housing.
