Heating zone with an illumination device for a cooking hob
An illumination device for a heating zone of a cooking hob. The illumination device comprises a light source element and a reflecting element. Further, the illumination device comprises an insulating layer horizontally arranged within the heating zone. Said insulating layer includes a light channel formed as a cut-out. The illumination device comprises a reflecting, diffusing and/or refracting layer covering at least the light channel. The light source element and the reflecting element are arranged such that a light beam from said light source element is redirected by the reflecting element into the light channel.
