ABSTRACT:
The present invention is directed to an illuminated touch button system having a light ring element, a button element located within and surrounded by the light ring element and an array of light emitting diodes. The light ring element comprises a series of individual chambers situated substantially over each light emitting diode in the array. In the preferred embodiment, each chamber includes a set of three light-receiving triangulated surfaces, these surfaces having a series of edges which act to diffuse the illumination of the light emitting diodes. The chambers, in combination with the edges, produce a relatively even, bright light distribution in the portion of the light ring element surrounding the button element.
