Publication number: 20190137092Abstract: A lighting device for lighting an interior of a domestic electrical appliance is configured to be operated in different lighting modes which differ from one another by the spectral composition of the light of the lighting device delivered into the appliance interior. In some embodiments, the lighting device comprises two light-emitting diodes which differ from one another in terms of the spectral content of the light delivered thereby. The different lighting modes of the lighting device differ from one another by a different operating combination of the light-emitting diodes. By varying the duty cycle and the pulse frequency of a pulse-width-modulated control signal, a control assembly is able to transmit two different pieces of control information to the lighting module in order to control the two light-emitting diodes individually.Type: ApplicationFiled: July 17, 2018Publication date: May 9, 2019Applicant: emz-Hanauer GmbH & Co.

Publication number: 20190107290Abstract: A pyrolytic oven comprises a housing and a muffle delimiting a cooking chamber inside the housing. A lighting module serves to illuminate the cooking chamber, wherein the lighting module has a cooling structure with an arrangement of cooling extensions formed in particular as pins or ribs, which project into a gap between housing and muffle and have a convection effect in a cooking mode of the oven. A fan device of the oven is configured and controlled to generate an air flow encountering the cooling structure in the gap in a pyrolytic mode of the oven. The cooling structure of the lighting module further has a wall formation, which in pyrolytic mode generates a wind shadow relative to the air flow for a number of cooling extensions of the cooling structure arranged distributed in a transverse plane to the flow direction of the air flow.Type: ApplicationFiled: October 1, 2018Publication date: April 11, 2019Applicant: emz-Hanauer GmbH & Co.
