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.

Submersible light fixture with multilayer stack for pressure transfer

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.

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.
