The present invention relates to an illumination device (12) for a heating zone (10) of a cooking hob, in particular of an induction cooking hob. The illumination device (12) comprises at least one light source element (14) and at least one reflecting element (18). Further, the illumination device (12) comprises at least one insulating layer (18) horizontally arrangeable or arranged on the heating zone (10). Said insulating layer (18) includes at least one light channel (20) formed as a cut-out. The illumination device (12) comprises at least one reflecting, diffusing and/or refracting layer covering at least the light channel (20). The light source element (14) and the reflecting element (16) are arranged that a light beam from said light source element (14) is redirected by the reflecting element (16) into the light channel (20).
