Abstract: Industrial lighting device including a light source and a sealed housing containing the light source. The housing includes a support delimiting a housing window extending opposite the light source, a window pane sealing the housing window, and a sealing gasket extending along the periphery of the housing window and compressed between the window pane and the support. The device includes a filter extending in front of the housing window, outside the housing. The filter includes a frame defining a frame window which is removably fixed to the housing, in an assembled position in which the frame window is opposite the housing window, and an optical film fixed to the frame and sealing the frame window. The device includes an elastic compression member arranged between the support and the frame.

Abstract: A method for parameterizing a machine-vision device. The method incudes the e following successive steps: a) selecting, depending on the zone of interest, a slaved lighting configuration, and recording the slaved lighting configuration in the control interface and/or applying the slaved lighting configuration; b) independently of step a), selecting an origin lighting configuration, and applying the origin lighting configuration; c) establishing an informational relationship between said origin and slaved lighting configurations and recording said relationship in the control interface so that the electronic unit commands the zone of interest to be lit in the slaved lighting configuration in response to an origin lighting configuration.
