Zusammenfassung: | A light transmitter (e.g., pipe) is constructed from polycarbonate for increased shock resistance and can define a rectangular cross section. A chamfered end of the light pipe is textured or frosted to further diffuse refracted light passing through the end to present a more even effect. A conical/tapered diffuser within the light pipe is illuminated by a reflector that reflects a plurality of rear-ward-directed illumination sources back into the diffuser. The reflector can direct light into the forwardmost, remote regions of the diffuser to generate a better spread of light and alleviate spotting effects. The illumination sources can be multi-colored sources that respond to a controller to project a color and/or blink in a pattern to indicate various conditions. The controller can operate individual portions of the ring so that only corresponding portions of the light pipe perimeter are illuminated in a particular color at a given time. Different quadrants may be simultaneously illuminated in different colors. |
