Abstract: An assembly (100) for the illumination of a wellbore, pipeline, tank, vessel or other environment wherein light is diffused and transmitted through an optically transparent material and projected in and around a field of view of a camera lens (10). A light source is disposed within a cavity at the proximal end (102) of a cylindrical shaped, optically transparent material. Light from the source is received into the transparent material, diffused, and transmitted to the distal end of the light tube (30), where it is projected in front of and around a field of view of a camera. Control of light intensity may be variable, pre-set before operations, or fixed by component design.

Abstract: An assembly (100) for the illumination of a wellbore, pipeline, tank, vessel or other environment wherein light is fused and transmitted through an optically transparent material and projected in and around a field of view of a camera lens (10). A light source is disposed within a cavity at the proximal end (102) of a cylindrical shaped, optically transparent material. Light from the source is received into the transparent material, diffused, and transmitted to the distal end of the light tube (30), where it is projected in front of and around a field of view of a camera.

Abstract: A downhole camera assembly (100) comprises a camera having a side-view viewport (82) that can be conveyed and manipulated within a wellbore on flexible cable. Light emitted from a light source is diffused and directed by a transparent or translucent material (61) in a substantially 360-degree pattern within a wellbore, thereby illuminating portion(s) of the wellbore positioned laterally to the camera assembly in a field of view of the viewport. The viewport may be selectively rotated 360 degrees by a motor assembly (40) positioned within the camera assembly which can be controlled from the earth's surface.
