Advanced Illumination
Advanced illumination are specialists in machine vision lighting, aiming to reduce or eliminate issues encountered when implementing factory automation lighting solutions.
Ai was the world’s first LED lighting company, shipping its first solid-state illumination systems in 1993. OEM Automatic has been in partnership with Ai for over a decade, and we are proud to represent a true leader in the field of machine vision lights.
There are a number of areas you need to think about in order to determine what type of illumination is the best solution for your application:
Bar lights
Because of the variety of lengths available, bar lights are useful for large area illumination when used in opposing pairs or in a picture frame mounting orientation. Bar Lights can also be used in replacement of Spot or Ring Lights when greater intensity is required.
Ring lights (bright field)
Bright Field Ring Lights provide illumination directly onto an object, at angles of above 45 degrees from horizontal, creating distinct shadows or general purpose illumination depending on subjects features.
Ring lights (dark field)
Dark Field Lights provide illumination that is projected at a shallow angle to the imaging surface, 45 degrees or less. Very low angle dark field ring lights must be deployed at close working distances to be effective.Back lights
Back Lighting provides an area of uniform illumination which when oriented behind the object of interest it can be used to create a part silhouette of instant contrast between dark and light.
Flat and dome lights
Dome Lights provide diffuse lighting, also known as “cloudy-day illumination”. Reflected light provides non-directional, soft illumination that is free of shadowing.
Flat Diffuse Lights are often referred to as “Flat Domes” because of the similar performance characteristics they share with classic domed illuminators. If sufficiently over-sized compared with the object of interest, flat diffuse lights can provide an adequate “Cloudy Day” lighting effect at a larger range of working distances than domes.
Line Scan lights
Line Lights, as opposed to linear array bar lights, employ a secondary lens to focus the light into a narrow beam, typically for short to intermediate working distances, and are mostly used in conjunction with line scan cameras.
Spot lights
They may be used to create both bright field and dark field effects, depending on the light angle of incidence. Working distances can be short to long, depending on available intensity and beam spread. Small spot lights are beneficial when deployed in tight spaces.
Coaxial lights
Coaxial Lights provide a type of diffuse illumination, generated from an internal source. The light is then deflected downward onto the imaging plane via a 50% beamsplitter, which also allows light from the object to be collected by the camera above.
