LEDs support multiple vision applications
With efficiencies and power improving, high-brightness LEDs find general and niche machine-vision applications.
The unique properties of high-brightness light-emitting diodes (HBLEDs) compared to incandescent, fluorescent, and gas-discharge lamps has pushed solid-state lighting (SSL) deep into the machine-vision market. According to analysts, such as Robert Steele at Strategies Unlimited, approximately 50% of all machine-vision illuminators are solid-state, and machine vision accounts for approximately $13 million in global sales of HBLEDs.
