摘要:
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.
摘要:
A deep submersible light may include a body defining a hollow interior and a solid state light source such as a plurality of high brightness LEDs mounted in the interior of the body. A transparent window may be mounted over the LEDs. The space between the transparent window and the LEDs may be filled with an optically transparent fluid, gel, or grease, which allows light to pass through and ambient water pressure to pass in, thus pressure compensating the LEDs by allowing them to see ambient water pressure. The transparent window may be mounted in the body for reciprocation in both a forward direction and a rearward direction to accommodate volumetric changes in the compensating fluid, gel, or grease caused by changes in temperature and water pressure as the manned or remotely piloted submarine travels from the sea surface to deep ocean depths.

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.

摘要:
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.

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.
摘要:
LED lights including a metal core printed circuit board (MCPCB) having a rear side and a front side are disclosed. At least one LED may be mounted to the front side of the MCPCB. A transparent window may be mounted and sealed to the front side of the MCPCB to enclose the LED. A portion of the MCPCB may extend from the transparent window so that it can be in heat exchange contact with water when the window of the lighting fixture is submerged in water or other fluids.
