The article discusses the use of high-brightness light-emitting diodes (HBLEDs) for multiple machine-vision applications. Analysts, including Robert Steele at Strategies Unlimited, notes that approximately 50% of all machine-vision illuminators are solid-state lighting and machine vision accounts for estimated $13 million in global sales of HBLEDs. It states that white-light HBLED designs have generated more that 70= 80 lm/W, compared to 80 lm/W for a fluorescent lamp.
