Smart Vision Lights, a manufacturer of LED illumination for machine vision applications, introduced the DFLW-200 dark field washdown ring light, the company says. Available in an anodized black aluminum housing, the IP68-rated, large-diameter light features the multi-drive driver, which allows the light to work in continuous operation or OverDrive strobe mode. Additionally, SafeStrobe technology applies safe working parameters to ensure that high-current LEDs are not damaged when driven beyond their limits. The DFLW-200 uses a microlens turning film. When combined with high-power LEDs, the microlens turning film directs a beam of light at a 25-degree angle toward the object, resulting in a highly concentrated and uniform field of illumination, the company says. The technique gives large-diameter dark field ring lights an extended working distance with no loss of light intensity or uniformity, the company says. Other features include an industry-standard 5-pin M12 connector that makes for simple wiring and a 1–10V DC analog signal line that gives the user total control over intensity in continuous operation mode.
