Definitions
- the present invention relates to a lamp housing in which one or more Wells should be introduced.
- sheet metal plays an important role in numerous technical fields Role. So components made of sheet metal are usually made by first flat sheet metal part is punched out and then brought into the desired shape. The sheet metal parts are not only folded or bent around specific axes, but often deformed so that depressions or indentations are formed become.
- Fig. 1 is a recessed ceiling light 1 shows in section.
- the lamp housing 2 is through a box-shaped sheet metal trough formed, which is to be attached to a (not shown) ceiling.
- Fasteners in the form of locking elements 11 are used.
- On the bottom these locking elements 11 become, for example, a reflector 5 and one in front of it arranged diffuser 6, on which in turn a grid 7 and the lamp 8th to be ordered.
- the attachment of the reflector 5 and the diffuser 6 in the Luminaire housing 2 takes place in that the locking element 11 through a hole in the Passed through the bottom of the lamp housing 2 and then rotated and so that it is locked.
- the present invention is therefore based on the object of the deformation To make sheet metal parts easier and more flexible to form recesses.
- the luminaire housing according to the invention has at least one shaping area that consists of a deformation field and several connecting webs between which there are free fields, with the deformation field at least partially over the connecting webs are connected to the surrounding metal sheet.
- the Connecting webs run in this way or are shaped so that they are under pressure stretch on the deformation field or change its position, so that in succession of which the deformation field permanently emerges from the surrounding metal sheet.
- the effort for deforming the Forming area significantly reduced compared to the surrounding area, because only the connecting webs have to be stretched and / or bent.
- the the forces required for this are, however, significantly lower than in the case of deformation of a completely closed sheet.
- Another advantage is that depending on Shape and arrangement of the molding area different shapes and depths for the depression to be introduced into the sheet metal part can be realized without a separate stamping die must be used for this.
- the lamp 1 shown in FIG. 1 with the bottom 3 of the lamp housing 2 introduced recess 4 has already been explained above.
- the 2, which is used to form the luminaire housing 2 is used to be explained in more detail.
- the flat sheet metal part 12 shown in FIG. 2 is made from a single flat sheet metal punched and then into the box-shaped structure to form a Luminaire housing deformed.
- the four around the bottom 3 arranged side areas 13 bent downward so that the in Fig. 1st structure shown results. This bending of the side parts 13 is with a relatively low effort possible.
- two Forming areas 14 deformed relative to the bottom 3 to the two after to form internally projecting recesses 4 for receiving the locking elements 11 for Attachment of the lamp elements are provided in the housing 2.
- One of the two shaping regions 14 is shown enlarged in FIG. 3. It exists from a circular central deformation field 15, as well as from several Deformation field 15 connecting with the surrounding area of the bottom side 3 Crosspieces 16 and 17, between which free fields 18 and 19 are arranged.
- the free fields 18, 19 are introduced to form the connecting web 16, 17 already during the punching out of the sheet metal part 12.
- the connecting webs 16, 17 are each concave or convex curved, wherein each two adjacent connecting webs 16, 17 arranged symmetrically to each other are. This has the advantage that when pressure is exerted on the deformation field 15 a uniform force distribution on the connecting webs 16, 17 is achieved. In the center of the deformation field 15 is also punched a hole 20 through which the in Fig. 1st locking element 11 shown can be passed.
- the recess 4 is formed in that 15 pressure on the deformation field is exercised so that this from the plane of origin formed by the bottom side 3 is lifted out.
- the connecting webs 16 and 17 depending on the depth of the Recess stretched longitudinally around their curved regions 16a and 17a. The one for this necessary force is significantly lower than the insertion of a depression in one closed sheet.
- FIG Fig. 4 Another possibility for a shaping region 14 according to the invention is shown in FIG Fig. 4 shown.
- the connecting webs 16 are straight and connect the deformation field 15 in a non-radial manner to the surrounding one Area of the bottom side 3.
- pressure is applied to the deformation field 15 exercised, the connecting webs 16 change their position such that the Deformation field 15 from the original plane with a slight rotational movement emerges.
- the effort for deforming is thus reduced of the sheet for forming depressions reduced so that the purchase very expensive stamping dies are no longer necessary.
- you can the shape and structure of the recesses are flexible.
