The invention relates to an oven light for electric stoves, consisting of a corresponding one Installation opening of an oven wall insertable cup-shaped holder made of sheet metal, one on this fixed lamp holder made of ceramic, the mouth-side edge of which is covered by an annular shielding part is covered with the formation of an air gap, and one on the mouth side can be screwed into the socket carrier Cover glass, the shielding part being a flat ring, the inner ring surface of which is conical to the mouth of the Socket carrier is arched towards, wherein the socket carrier is also bottomless and the Shielding part connected to the socket carrier via at least one molded radial arm and is consequently formed in one piece with the socket carrier, which can be bent backwards on the shielding part Fastening tabs for fastening the lamp socket are cut.

Such an oven light is known from DE-OS 13 542. In this known lamp is / was a protection of the ceramic socket against the rays of the screwed-in lamp or other Reached heat sources, although the production of this advantageous oven light per se is somewhat complex, as is the assembly. In the case of the known light fixture is namely for attachment the ceramic socket on the cup-shaped socket carrier or on the shielding part another, separate sleeve-shaped sheet metal part required, which mitiels the set or bending flap with the Socket carrier is connected, with the lamp socket again to be arranged in this sleeve-shaped part To produce this oven light are a) .o two separate sheet metal parts and the ceramic lamp holder required. Also during the assembly, several work steps are necessary, namely the connection of the actual pot-shaped housing with the interposed sleeve-shaped socket holder and the connection of the socket with the Frame position.

Since oven lights are mass-produced items, any relief in the production or Assembly is associated with considerable technical progress, with the functionality of the oven light However, under no circumstances should it suffer from this.

Based on this, the object of the invention is to create an oven light of the type described at the outset, which is easier to set up and assemble while maintaining the advantages of the known lamp.

To solve this problem, the invention proposes that the lamp socket is attached directly to the shielding part, that the lamp socket is integrally formed Has holding projections, behind which the fastening tabs are bendable, the shielding part in the Fastening layer only rests selectively in the area of the fastening tabs on the edge of the frame.

The inventive design is achieved that the previously necessary metallic intermediate part for Coupling of lamp holder and housing can be omitted. Through the arrangement of fastening projections on the ceramic body of the lamp socket, it is possible to attach the fastening tabs of the To bend shielding part immediately behind these fastening projections, so that an immediate Bracket of the lamp holder can be done on the one-piece sheet metal part. In addition, the Fastening extremely secure, as a form-fitting connection has been created. Through this Training is the production effort with regard to the individual parts of the oven light compared to the state the technology is considerably reduced, while at the same time at least one assembly step is omitted during assembly can come.

In addition, it is ensured that only an extremely low heat conduction between the metallic Housing part and the ceramic socket is possible. The area of heat conduction is namely on the fastening tabs limited, which are only linear in small areas directly on the lamp holder or rest against their projections.

In addition, it is ensured that although the unimpeded passage of the lamp cap to Screwing into the lamp socket is still possible, but a shielding of the lamp socket mouth takes place so that the edge of the ceramic socket is not exposed to the rays of the screwed-in lamp is still stressed by the other heat rays. The shielding part is only selectively on the Edge of the version or behind the projections of the version and essentially leaves an air gap

between you and the socket free so that the heated Air can flow out well.

It is also advantageous that the shielding part is connected to the socket carrier via two diametrically opposed arms is connected, a fastening tab being cut free from each arm.

In variation it is provided that the shielding part is connected to the socket carrier via three arms, which on one side cover about a third of the scope of the shielding part are arranged distributed, wherein the screen part is arranged obliquely to the socket support mouth

The inclination is known per se from the prior art. Due to the inclination, at reduced overall height, an even better air circulation is achieved

F i g. 6 the detail in plan view.

The oven lamp consists essentially of a socket carrier 2 made of sheet steel that can be inserted into a corresponding opening in an oven wall 1, a ceramic lamp socket 3 attached to this and provided with electrical contacts, a lamp 4 screwed into this, and a cover glass that can be screwed into the socket carrier 2 5. In the exemplary embodiment (FIGS. 1 to 3), the socket carrier 2 is fastened in the oven wall 1 by means of the spring plates 6. The edge 3 'of the lamp socket on the mouth side is covered by an annular shielding part 2 · », the inner ring surface 2 ^b is conically bulged towards the mouth of the frame support 2 ίο. As a result, on the one hand, an air gap is formed between the lamp holder 3 and the shielding part 2 ^a (with the exception of the attachment points) and, on the other hand, a certain diffuse reflection of the incoming rays is achieved.

The socket-holder 2 is formed bottomless substantially and the shield member 2 'is integrally connected via radial arms 2 ^C therewith.

According to the exemplary embodiment (FIGS. 1 to 3), two arms 2 ^{C are} provided, a fastening lip 2 ^{d being} cut out and bent over from each arm 2 ^C. These fastening tabs 2 ^d are bendable behind corresponding protrusions 3 * of the lamp socket 3 for fastening it.

According to the variant (FIGS. 4 to 6), the shielding part 2 ^{a is} connected to the socket carrier 2 via three arms 2 ^C , which are distributed on one side over about a third of the shielding part circumference. The shielding part 2 ' is inclined towards the socket support mouth at an angle of approximately 60 °.
