Abstract: Lighting apparatus for high pressure underwater use are disclosed. In one embodiment the lighting apparatus comprises a housing for withstanding ambient exterior pressure at a depth of approximately 500 feet or more, a transparent pressure bearing window positioned at a forward end of the housing, and a multilayered stack for bearing substantially all of the loading applied to the transparent pressure bearing window at a depth of approximately 500 feet or more disposed in the housing behind the transparent pressure bearing window is disclosed.

Abstract: Submersible lights including housings and a multilayer stack for pressure transfer are disclosed. A transparent pressure-bearing window, a window support structure, a circuit element populated with LEDs, and a pressure support structure may be mounted inside the housing. The support structure may be structured to bear at least some of the pressure applied to the transparent window from external pressure sources. The support structures may also be adapted to transfer thermal energy to an exterior environment such as sea water.

Abstract: Lighting device embodiments having a housing enclosing one or more interior volumes, a metal core printed circuit board, a multilayer stack of spacers, and a serviceable port in the housing to allow venting of one or more of the interior volumes are disclosed.

Abstract: An integrated underwater imaging device includes a housing with a transparent optical port, a camera and one or more LED light sources with optically coupled to light pipes within the housing. The optical port includes light mitigation features to reduce internal light contamination from the LED light sources on the imager of the camera.

Abstract: An underwater light or submersible luminaire may include a housing and a transparent pressure bearing window positioned at a forward end of the housing. A window supporting structure may be mounted in the housing behind the transparent window. A printed circuit board element having a plurality of LEDs may be positioned within the housing behind the window supporting structure to bear substantially all of the ambient water pressure applied to the transparent window.

Abstract: An underwater LED light for use in high ambient pressure environments having a housing, a transparent pressure-bearing window, an MCPCB having one or more LEDs, and a multilayer stack of spacers for carrying loads applied to the window to the MCPCB and to the housing.

Abstract: Environmental lighting assemblies are disclosed that may include a structural element, which may be a tubular J-shaped element or other shape or structure, as well as a driver module and an LED lighting engine assembly with a removable locking assembly for generating output light to streets, the ground, trees, or other surfaces, objects, or structures.

Abstract: 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.
