Abstract

The invention relates to a display lamp with lamp sections, which are releasably arranged one above the other and wherein each comprises a transparent housing section with an insertion unit. The insertion unit has electrical conductors, which are connected via electrical connecting structure with the conductors of the respective insertion units arranged below or on the base of the display lamp. Furthermore the insertion units provide receiving devices for the display lamps, which are connected with the conductors. The connecting structure comprise pins and sockets extending in the axial direction. One lamp section can be axially plugged into the lamp section or base respectively arranged below it in such a way that the pins and sockets connect the conductors of the insertion unit with the conductors, arranged respectively below, of the insertion unit located below, wherein the lamp sections are connected via snap-in connections with the lamp section or base respectively located below it.

Claims

1. An illuminated display column, comprising a plurality of lamp sections releasably arranged one above the other, each lamp section having:

a transparent housing;

an insertion unit mounted to said transparent housing, said insertion unit having electrical conductors, and a receiving device defining an axial direction, for receiving a display lamp which when received is connected to said electrical conductors;

electrical connecting means comprising pins and sockets which extend in said axial direction, which are adapted to be connected to pins and sockets of adjacent lamp sections, and which when connected produce an electrical connection with said electrical conductors of the respective adjacent lamp sections; and

snap-in connecting means, wherein one lamp section can be axially plugged into an adjacent lamp section by said snap-in connecting means, and as such said electrical conductors of said adjacent lamp sections are electrically connected.

2. The illuminated display column as defined in claim 1, wherein each lamp section further having:

switching means through which a defined conductor of said electrical conductors, and therefore a defined display function is assigned to the display lamp of the respective lamp section.

3. The illuminated display column as defined in claim 2, wherein each lamp section further having:

spaced apart plates connected to each other by said electrical conductors, wherein said switching means is arranged on one of said plates, and wherein said pins and/or sockets are provided on the side of said plates facing away from the other plate.

4. The illuminated display column as defined in claim 1, wherein each insertion unit has a bottom plate.

5. The illuminated display column as defined in claim 1, wherein said snap-in connecting means have snap-in and insertion means arranged in the area of the front faces of said transparent housing.

6. The illuminated display column as defined in claim 1, wherein instead of or in addition at least one lamp section of said plurality of lamp sections is provided with a section having an acoustic signal emitter.
