Illumination system for cavities

摘要

A system to light a cavity 19 in an appliance. A source or light emitter 27 is mounted on a circuit board 32, so that the light emanating from said source or light emitter 27, is concentrated into a light beam using an optical collimator system 28 or in some cases a Fresnel arrangement; wherein the foregoing elements may be found outside a door 14, which allow access into the cavity; thus the light beam exiting the optical collimator 27 or Fresnel arrangement travels a distance though air between the optical collimator system 27 or Fresnel arrangement and the upper face of the light guide 29 which is placed on the door 14, the light guide 29 transports the luminous flux towards a notch which diverts said luminous flux directing into the cavity's 19 interior.
