A microelectromechanical light emitter component comprises an emitter layer structure of the microelectromechanical light emitter component and an inductive structure of the microelectromechanical light emitter component. The inductive structure of the microelectromechanical light emitter component is configured to generate current in the emitter layer structure by electromagnetic induction, such that the emitter layer structure emits light. The emitter layer structure is electrically insulated from the inductive structure.

The invention relates to an infrared device comprising a resistive element suspended in a cavity formed in a main element, and capable of transmitting infrared radiation when it is fed with an electric current. In particular, the main element is at least partly covered on the outer surface thereof and/or the inner surface thereof with a reflective coating. The use of the reflective coating makes it possible to at least partly contain infrared radiation transmitted by the resistive element in the cavity.

An infrared emitter that comprises a cladding tube made of quartz glass that surrounds a heating filament as an infrared radiation-emitting element that is connected via current feedthroughs to an electrical connector outside the cladding tube. To improve the service life and power density, the heating filament comprises a carrier plate with a surface made of an electrically insulating material, whereby the surface is covered by a printed conductor made of a material that generates heat when current flows through it.
