Abstract
A lighting system for a logging instrument probe for inspecting a passageway having different diameters. The lighting system has a light assembly of a plurality of light sources arranged in tandem. The light assembly is mounted under the sensor to selectively illuminate that part of the passageway lying within the sensor's field of view. Three extension legs are used to rigidly mount the light assembly forward of the sensor camera and at least one leg provides a conduit for the electrical wires used for powering the lights. The first light source is reverse facing. The length of the legs is selected to position a first light source at a particular distance away from the camera for inspection of the part of the passageway having the smaller size. A second light source is mounted in the light assembly and is forward facing. Connected between the first light source and the second light source is a spacer. The length of the body section of the spacer is selected to space the second light source from the camera by an amount which will provide a sufficient amount of light in the field of view of the camera for the larger part of the passageway.
