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, wherein the insertion unit has electrical conductors, which are in connection via electrical connecting means with the conductors of the respective insertion units arranged below or on the base of the display lamp, and wherein furthermore the insertion units provide receiving devices for the display lamps, which are connected with the conductors.

The invention is distinguished in that the connecting means comprise pins and sockets extending in the axial direction, and that 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. A display lamp (1) with lamp sections (11 to 17), which are releasably arranged one above the other and wherein each comprises a transparent housing section (25) with an insertion unit (27), wherein the insertion unit (27) has electrical conductors (47, 49), which are in connection via electrical connecting means with conductors (47, 49) of the respective insertion unit (27) arranged below or on the base (9) of the display lamp (1), and wherein furthermore the insertion units (27) provide receiving devices (31) for the display lamps (33, which are connected with the conductors (47, 49), characterized in that the connecting means comprise pins (39, 41) and sockets (43, 44) extending in the axial direction, and that one lamp section (11 to 17) can be axially plugged into the lamp section (11 to 17) or base (9) respectively arranged below it in such a way, that the pins (39, 41) and sockets (43, 44) connect the conductors (47, 49) of the insertion unit (27) with the conductors (47, 49), arranged respectively below, of the insertion unit (27) located below, wherein the lamp sections (11 to 17) are connected via snap-in connections with the lamp section (11 to 17) or base (9) respectively located below it.

2. The display lamp (1) in accordance with claim 1, characterized in that each lamp section has a switching means (45), through which a defined conductor (21, 23, or 47, 49), and therefore a defined display function is assigned to the display lamp (33) of the respective lamp section (11 to 17).

3. The display lamp (1) in accordance with claim 1 or 2, characterized in that the insertion units (27) in the areas of the two front faces of the lamp sections (11 to 17) each have a plate, wherein the two plates (35, 37) are connected with each other by means of the conductors (47, 49), that the switching means (45) is arranged on one of the plates (35, 37), and that the pins (39, 41) and/or sockets (43, 44) are provided on the side of the plates (35, 37) which are respectively facing away from the other plate.

4. The display lamp (1) in accordance with claim 1, 2 or 3, characterized in that the insertion units (27) each contain a bottom plate.

5. The display lamp (1) in accordance with one of the preceding claims, characterized in that the snap-in connections have snap-in and insertion means arranged in the area of the front faces of the transparent housing sections.

6. The display lamp (1) in accordance with one of the preceding claims, characterized in that instead of or in addition, at least one lamp section (11 to 17) with a display lamp (33) is provided with a section with an acoustic signal emitter.
