Abstract: Lights with features for underwater use that provide tailored beam-width and/or other tailored light patterns are disclosed. One embodiment includes a housing having a front end with a port and a back end, a port window having a plurality of lens features positioned at the front end of the housing within or behind the port, and a circuit element, including a plurality of LED lighting elements, positioned behind the window.

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: 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.

Abstract: A submersible luminaire includes forward and aft housings that couple together. A transparent pressure-bearing window, a window support structure, a circuit element populated with LEDs, and a pressure support structure are mounted inside the forward housing. The support structures are configured to bear at least some of the pressure applied to the transparent window from external pressure sources. The support structures are further configured to transfer thermal energy to an exterior environment.
