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.
