Patent number: 10401017Abstract: 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.Type: GrantFiled: November 16, 2016Date of Patent: September 3, 2019Assignee: DEEPSEA POWER & LIGHT LLCInventors: Ray Merewether, Mark S. Olsson, Jon E. Simmons, John R. Sanderson, IV, Aaron J. Steiner

Patent number: 10352550Abstract: A submersible luminaire includes a housing and a transparent pressure bearing window positioned at a forward end of the housing. Window supporting structure is mounted in the housing behind the transparent window. A water-tight seal is located between the window and the housing. A circuit element is configured and positioned within the housing behind the window supporting structure to bear at least some of the pressure applied to the transparent window. At least one solid state light source is mounted on the circuit element behind the transparent window.Type: GrantFiled: July 27, 2010Date of Patent: July 16, 2019Assignee: DEEPSEA POWER & LIGHT LLCInventors: Mark S. Olsson, John R. Sanderson, IV, Brian P. Lakin, Steven B. Weston, Jon E. Simmons

Patent number: 10222031Abstract: 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.Type: GrantFiled: February 13, 2017Date of Patent: March 5, 2019Assignee: DEEPSEA POWER & LIGHT LLCInventors: Mark S. Olsson, Jon E. Simmons, John R. Sanderson, Aaron J. Steiner

Patent number: 10215394Abstract: 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.Type: GrantFiled: March 14, 2016Date of Patent: February 26, 2019Assignee: DEEPSEA POWER & LIGHT LLCInventors: Mark S. Olsson, John R. Sanderson, IV, Steven B. Weston, Jon E. Simmons, Brian P. Lakin
