Abstract:
A light pipe structure for a dimmer switch comprises a continuous status indicator lens and a plurality of light pipes, which are operable to conduct the light from a plurality of discrete sources to the lens. The light conducted from one of the discrete sources through a light pipe generates a pinpoint of light on the front surface of the lens. The pinpoint of light is surrounded by a diffusion of light across the front surface of the lens, which produces an aesthetically-pleasing effect by increasing the uniformity of the illumination across the front surface of the status indicator lens. The light pipes are coupled to the lens via a plurality of rounds, which provide for diffusion of light around the pinpoint of light on the lens. The light pipes may comprise light-refracting structures, which the amount of light emitted from adjacent discrete sources from reaching the front surface of the lens.
