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.
Claims6
An illuminated touch button system for controlling an electrical function, said touch button system comprising:
- a light ring element having a top ring portion of light transmitting material, an upper portion having a solid interior of light transmitting material, and a bottom portion;
- a button element located within said light ring element and surrounded by said top ring portion;
- an array of peripherally-spaced light emitting diodes at least partially located within said bottom portion of said light ring element, said array being illuminated upon contact of said button element by a user, said upper portion transmitting the illumination from said array to said top ring portion, thereby providing visual feedback to the user;
- said upper portion of said light ring element having an interior surface comprising a plurality of chambers spaced about the periphery of said upper portion, wherein each light emitting diode is located below one of said chambers;
- and
- each of said chambers including an inclined surface having a series of Fresnel-like edges facing its respective light emitting diode for diffusing the illumination of said array.
An illuminated touch button system for controlling an electrical function, said touch button system comprising:
- a light ring element having a top ring portion of light transmitting material, an upper portion having a solid interior of light transmitting material, and a bottom portion;
- a button element located within said light ring element and surrounded by said top ring portion;
- an array of peripherally-spaced light emitting diodes at least partially located within said bottom portion of said light ring element, said array being illuminated upon contact of said button element by a user, said upper portion transmitting the illumination from said array to said top ring portion, thereby providing visual feedback to the user;
- said upper portion of said light ring element having an interior surface comprising a plurality of chambers spaced about the periphery of said upper portion, wherein each light emitting diode is located below one of said chambers;
- and
- each of said chambers including a set of at least two, light receiving, triangulated surfaces inclined down toward its respective light emitting diode.
An illuminated touch button system for controlling an electrical function, said touch button system comprising:
- a light ring element having a top ring portion of light transmitting material, an upper portion having a solid interior of light transmitting material, and a bottom portion;
- a button element located within said light ring element and surrounded by said top ring portion;
- an array of peripherally-spaced light emitting diodes at least partially located within said bottom portion of said light ring element, said array being illuminated upon contact of said button element by a user, said upper portion transmitting the illumination from said array to said top ring portion, thereby providing visual feedback to the user;
- and
- said upper portion of said light ring element having an exterior, centrally-directed side having a center-line axis, said side having a conical surface which produces diffusion reflection for the illumination traveling within its solid, light transmitting material, said conical surface at least partially reducing the illumination from said light emitting diodes to the open interior of said upper portion.
