This invention provides a vision system with an exchangeable illumination assembly that allows for increased versatility in the type and configuration of illumination supplied to the system without altering the underlying optics, sensor, vision processor, or the associated housing. The vision system housing includes a front plate that optionally includes a plurality of mounting bases for accepting different types of lenses, and a connector that allows removable interconnection with the illustrative illumination assembly. The illumination assembly includes a cover that is light transmissive. The cover encloses an illumination component that can include a plurality of lighting elements that surround an aperture through which received light rays from the imaged scene pass through to the lens. The arrangement of lighting elements is highly variable and the user can be supplied with an illumination assembly that best suits its needs without need to change the vision system processor, sensor or housing.

A lighting apparatus including: a flexible planar light source having plural illuminants over a surface of a planar carrier material, which includes a flexible planar circuit carrier fitted with the illuminants on a side. The illuminants being interconnected by electrical lines formed in or on the circuit carrier, and a controller to supply power to the illuminants and control the illuminants. The controller includes a housing disposed on an edge of the planar light source and is mechanically connected to the planar light source, an edge of the planar light source being partly accommodated in the housing. The housing including electrical and electronic components and lines connected to the electrical lines of the planar light source. A strain relief is configured to absorb tensile stresses between the housing and the planar light source to keep the tensile stresses away from electrical connections between the controller and the planar light source.

The lens attachment includes a body that overlays a lens of an image capture device and one or more lights integrated with the body that emits light in a direction so that the light is not directed into the lens of the image capture device. The lens attachment includes a connector integrated with the body that secures the lens attachment against a housing of the image capture device.

Inspection assemblies that include one or more sideview cameras for capturing images of an interior surface of a pipe or conduit include an elongate housing, a sideview camera within the housing and arranged to capture an image of a region within a field of view external to the housing, and a viewport element mounted in the housing and located such that light is transmitted through the viewport element and into said sideview camera, wherein the viewport element has a concave internal surface, closer to the camera, and a convex external surface, further from the camera, and wherein the centre of the radius of curvature of the internal surface is closer to the viewport element than the centre of the radius of curvature of the external surface.

The vision system housing includes a front plate that optionally includes a plurality of mounting bases for accepting different types of lenses. An optional connector is provided on the front plate to accept an electrical connection for a liquid lens component. The front plate includes a connector that allows removable interconnection with the illustrative illumination assembly. The illumination assembly includes a cover that is light transmissive on at lest the front face thereof. The cover encloses an illumination component that can include a plurality of lighting elements that surround an aperture through which received light rays from the imaged scene pass through to the lens. The rear face of the illumination component is spaced apart from the rear edge of the cover, which removably and sealingly engages the front plate. The assembly also includes a connector that removably engages the connector on the front plate. The arrangement of lighting elements (e.g. LEDs) is highly variable and the user can be supplied with an illumination assembly that best suits its needs without need to change the vision system processor, sensor or housing.

A lighting device is disclosed having a plurality of LED chips mounted on a single planar flexible substrate, wherein the single planar flexible substrate is disposed in an arcuate orientation. A heat sink having an arcuate surface shaped to approximate the arcuate orientation of the flexible substrate is coupled to the flexible substrate between complementary arcuate surfaces. A luminescent coating is disposed about a top surface of the arcuate single planar flexible substrate.

Described is a recording device holder apparatus comprising a substrate comprising an outer perimeter, a front face, and a back face, wherein the front face is reflective, wherein the front face and the back face extend along the longitudinal axis and the lateral axis, and the substrate further comprises an inner perimeter defining a void space, wherein the void space extends from the front face to the back face, wherein the inner perimeter is completely within the bounds of the outer perimeter; and a device mounting system attached to the substrate via a fastener, wherein the fastener is interfaced with the back face or the front face and back face of the substrate, such that the device mounting system is configured to position a visual recording device substantially in the same plane as the longitudinal axis and the lateral axis and within the void space.
