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: A light for use in high ambient pressure environments having a hollow housing comprising a front and rear section and at least one LED is disclosed. A transparent window may extend across an aperture in the housing and a seal may be positioned between the front and rear sections.

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: Lighting device embodiments having a housing enclosing one or more interior volumes, along with a serviceable port in the housing to allow venting of one or more of the interior volumes, are disclosed. The lighting devices may further include internal venting paths to allow transfer of contaminating gases to the serviceable port, and a gas permeable pressure valve to allow transfer of contaminants from the interior of the lighting device. The pressure valve may be selectively permeable as a function of applied exterior pressure. The lighting device may also include one or more electronic circuit elements disposed in the one or more interior 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 to allow diffusion of browning contaminants from the one of the interior volumes to the gas or liquid volume exterior to the housing.

Abstract: Apparatus and systems for providing environmental lighting are disclosed. An environmental lighting assembly may include a structural element, which may be a tubular J-shaped element or other shape or structure, as well as 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. A projection element may be positioned relative to the output light from the LEDs to generate patterns, images, or other controlled light output.

Abstract: A deep submersible light fixture includes a substantially spherical exterior housing made of metal. The housing has a hollow interior and a first aperture extending through a front side of the housing. The first aperture communicates with the hollow interior of the housing. At least one LED is mounted inside the first aperture adjacent to the hollow interior of the housing. A transparent window extends across the first aperture. A seal is situated between a periphery of the window and the housing adjacent the first aperture for providing resistance to the entry of water into the hollow interior of the housing. An electrical connector extends through a second aperture in a rear side of the housing.
