    The invention relates to a cooking field plate of a ceramic material with a visible side and a lower side located opposite it. According to the invention, the cooking field plate has microperforations in at least a partial area for the transmission of light from the lower side to the visible side. Therefore, the micro-perforations advantageously form light channels through which light is transmitted and can be perceived by the user in the area of the surface of the visible side of the cooking-field plate. Accordingly, by means of a suitable arrangement of the micro-perforations, it is possible to represent on the visible side of the cooking field plate any type of information in the form of a sign, symbol, or marking, so that it is visible to the user.

    transparent of the microperforations 203, and can be perceived by the user in the surface area of the visible side 201 of the cooking field plate 206. Therefore, by an appropriate arrangement of the microperforations, it is possible to represent on the visible side 201 of the cooking field plate 206 any type of information in the form of a sign, symbol, or marking, so that it is visible to the user.
    In another embodiment of the invention, the voids of the microperforations 203 are filled with a transparent varnish in the blue spectral region (wavelength 480-420 nm), whereby the varnish acts as a blue chromatic filter. The lighting units 204 are made as white LEDs. In this exemplary embodiment, the blue light fraction of the emitted white light 205 is transmitted through the channels of the microperforations 203 by the varnish that acts as a chromatic filter.
    The lighting unit 204 may also comprise a light conductor that transports the light emitted by a light source from the light source to the microperforations that form the light channels. Then, the light sources can advantageously be installed in principle at any point of the cooking field housing. In addition, it is advantageously possible to transport the light from a light source through several light conductors to several light channels formed by microperforations.
    In another exemplary embodiment, the light conductors have on their side directed towards the microperforation at least one concave microlens that is oriented along a vertical axis with one or more light channels formed by microperforations. In this way, the light emitted by the light source is focused on a collimated beam that is oriented in the direction of the axis of the light channel.
    Figure 3 shows the comparison of a first cooking field plate 301 with a second cooking field plate 302, in perspective representation. The first cooking field plate 301 of ceramic material has a visible side 304 and a lower side 303. In this representation, the cooking field plate 301 is shown rotated, so that the two sides 303, 304 are inverted in comparison with the previous figures. The thickness of the first cooking field plate 301, that is, the spatial extent from the visible side 304 to the lower side 303, is constant over the entire surface of the cooking field plate 301.

    The second cooking field plate 302 of ceramic material has a visible side 304 and a lower side 303. In a partial area of the cooking field plate 302, a laminar drain 305 is observed on the lower side 303. In said area partial 305, the thickness of the second cooking field plate 302, i.e. the extension
    5 from the visible side 304 to the lower side 303, is reduced compared to the thickness of the remaining cooking field plate 302.
    In the partial area 305, the microperforations that form the light channels are provided, and which are not represented in Figure 3. Thanks to the smaller thickness of the partial area 305, the microperforations can be provided with a diameter
    10 particularly small, which is not possible in those areas of the cooking field plate 302 with greater thickness.
