Abstract
A visual task or status indicator comprises a tube having a riser region extending away from a base and an illumination output region distal to the riser region. The tube has the tube wall comprising an optical diffuser material. A waveguide, such as a polycarbonate strand or other optical fiber or a bundle of optical fibers, is enclosed within and extends through the riser region into the illumination output region of the tube. The waveguide is configured to emit light laterally in the illumination output region. A light source is coupled to the waveguide. The light source can have a plurality of output light modes, including various colors or intensities or patterns of colors and intensities. Control circuitry is connected to the light source to select the output light modes in response to a control signal. A plurality of indicators can be controlled from a central control hub.
