Abstract:
A light guide for transferring light within electrical equipment, comprising:(a) a frame, said frame including apertures whereby fasteners are receivable, said frame being suitable for mounting within a piece of electrical equipment; (b) a plurality of optical channels constructed from a material with a refractive and transmissive index capable of transmitting light, with each optical channel including: an optical input coupled to a light source within said piece of electrical equipment; and an optical output coupled to an outside surface of a bezel of said piece of electrical equipment; and (c) at least one optical prismatic section for each channel of the plurality of optical channels, said at least one optical prismatic section set an angle incident said optical channel operable to change the direction of light such that light is totally reflected within said optical channel so as to substantially prevent crosstalk among the plurality of optical channels.
