Power LEDs for Machine Vision Lighting

Facebook X LinkedIn Email
Higher current capabilities of power LEDs enable strobed lighting for vision systems.

Matt Pinter, Smart Vision Lights, and Christos Sarakinos, Future Lighting Solutions

Smart cameras, at a reduced price, have continued to increase capabilities for machine vision applications, but lighting has not kept pace. There is hope, however, if lighting designers take advantage of performance and packaging breakthroughs. For power LEDs, the relationship between the forward current and the light output is direct, assuming constant temperature. As DC forward current is increased, light output increases. The first power LED introduced in 1999 by Philips Lumileds had a nominal forward current of 0.35 A and maximum DC forward current of 0.38 A, leaving little room to...Read full article

    machine vision
    Machine vision, also known as computer vision or computer sight, refers to the technology that enables machines, typically computers, to interpret and understand visual information from the world, much like the human visual system. It involves the development and application of algorithms and systems that allow machines to acquire, process, analyze, and make decisions based on visual data. Key aspects of machine vision include: Image acquisition: Machine vision systems use various...
