Abstract
A lighting device for household appliances such as ovens, includes an electric lamp socket formed of electrically insulating material preventing leakage currents. Contact parts are disposed in the socket. The socket has an access side with a plug-in opening formed therein into which a lamp with a glass bulb, a lamp base of insulating material and contact prongs protruding from the lamp base is to be plugged into contact with the contact parts in a given plug-in direction. An electrically conductive and protectively grounded protective element covers at least the access side of the lamp socket and extends to the vicinity of at least one of the glass bulb and the lamp base. The protective element and the contact parts are spaced apart by a distance being greater than the length of the contact prongs by a required margin of safety, as seen in the given plug-in direction.
