Abstract

A pillar-shaped indicator lamp (1) is described with lamp sections arranged one on top of the other, which consist of transparent housing sections (4, 5) with inserted parts (7, 8), and in which the inserted parts have electrical lines (10, 10') which are in connection with the lines of the inserted part respectively arranged therebelow or of the base (3), and in which there are provided furthermore in the inserted parts the receiving devices for the indicator lamps which are in connection with the conductor tracks. In this process, the inserted parts (7, 8) are interconnected and form a unit. The housing parts (4, 5) are likewise interconnected and form a unit. The insert formed by the inserted parts can be removed from the housing upwards. <IMAGE>

Description

The invention relates to a display lamp column with lamp sections arranged one above the other, which consist of transparent housing sections with inserted insert parts, and in which the insert parts have electrical lines which are connected to the lines of the insert part or base arranged below them, and in which the insert parts furthermore the receiving devices for the indicator lights are provided, which are connected to the lines.

Such indicator lamp columns are known. For example, DE 22 11 801 shows an indicator lamp column with individual electrical supply to the individual luminaire sections via appropriate contact devices.

The disadvantage of this is that to replace the lamps, the individual lamp sections are disassembled and must be detached from the lamp section attached above. It is very cumbersome. When several lamps are exchanged at the same time, it is also possible to swap individual lamp sections or even entire groups of lamp sections. This can have undesirable consequences and dangers, especially in industrial applications, since this can lead to incorrect signals being emitted.

The object of the present invention is to eliminate the disadvantages mentioned above and, in particular, to simplify the disassembly required to replace lamps. Furthermore, the risk of interchanging individual color signals during repairs is to be reduced.

This object is achieved in that the insert parts are connected to one another and form a unit, and in that the housing parts are connected to one another and form a unit, and in that the insert formed by the insert parts can be removed upward from the housing.
Such a design makes repairs to the insert parts and the interchangeability of the lamps significant simplified. A mix-up of the color order in the display lamp column is also avoided.

Particularly advantageous embodiments of the invention are defined in the subclaims.

Figure 1 shows an indicator lamp column 1, in which the cover 2 fastened by screws is removed. These screws (not shown) are screwed through the cover 2 into corresponding fastening projections 2 'of the upper insert 4. On a base 3, which is connected to a power supply and corresponding has electrical distribution devices, two hollow cylindrical housing sections 4, 5 made of transparent differently colored (for example green, red) plastic material are arranged one above the other. The connection of the upper housing section 4 on the lower housing section 5 and the connection of the lower housing section 5 on the base 3 takes place by means of screws (not shown) which engage in corresponding fastening projections (such as 2 '). But it can also be done by appropriate geometric design or by means of adhesive. The housing sections 4, 5 are fixed to one another, albeit detachably, and form the housing. The arrangement of any number of housing sections 4, 5 one above the other is possible. A part of a bracket 6 of the upper insert 7 is visible in FIG. 1 within the upper housing section 4.

An insert part is arranged in each housing section 4, 5. The insert parts 7, 8 of the indicator lamp column 1 are shown in FIGS. 2 and 3. The insert parts 7, 8 are also firmly connected to one another and form an insert which can be gripped on the bracket 6 and removed as a whole without having to dismantle the housing. The upper insert 7 consists of a circuit board 9 (in which the bracket 6 is integrated) with conductor tracks 10, a carrier plate 11 and a lamp holder 12 for a lamp. Other lighting devices with corresponding Versions are also possible. The lamp holder 12 is fastened on the carrier plate 11 by means of fastening screws 13. The electrical connection between the conductor tracks 10, 10 'and the connecting cables 14, 14' of the lamp holder 12 is made by soldering.

The lower insert 8 consists of two boards 17, on which conductor tracks 10 are also attached. The lower lamp holder 18 is fastened on the lower support plate 11 by means of fastening screws 13. The electrical contact is also made by soldering the connecting cables 14, 14 'to the conductor tracks 10, 10'.

The mechanical connection of the insert parts 7, 8 and the electrical connection of the conductor tracks 10 of the circuit boards 9, 17 takes place via right-angled pins 19, 19 ', which are held in insulating elements 21 and each have one end on the conductor tracks of the one circuit board and with their other ends are soldered to the conductor tracks of the carrier plate 11. Thus, in FIG. 3, the conductor track (left side in FIG. 2) 10 on the left side of the circuit board 9 with the pins 19 ', these with the one ends of the conductor tracks 30 on the carrier plate 11 (see FIG. 3), the other ends with the pins 19 (Figure 2), these in turn connected to the conductor tracks 10 'on the right side of the board 17. The same applies to the connection on the right-hand side in FIG. 2. The lower insert part 8 is open the underside of the carrier plate 11 is provided with two electrical plugs 22 which engage in corresponding sockets (not shown) in the base 3. Such a plug connection ensures both electrical and mechanical contact. Both are released when the insert is pulled out of the housing.

The entire insert formed by the interconnected insert parts 7, 8 is removed by pulling out by means of the bracket 6. If more than two insert parts 7, 8 are provided, a bracket 6 integrated with the boards is provided on the uppermost insert part. The reinstallation takes place accordingly.

For easier, appropriate insertion of the insert into the housing formed by the housing sections, the housing sections 4, 5 have projections 23, 23 'which fit into the positioning cutouts 24, 24' provided on the carrier plates 11 (FIGS. 1 and 4). So that only positioning is possible, the projections 23 and 23 'or the positioning cutouts 24 and 24' are of different widths. The large recesses 25 are provided so that the fastening projections 2 'can pass through when the insert is inserted.

An alternative to this type of guide can be constructed such that the board 17 in on both sides Guide grooves is guided, which are arranged opposite one another in the interior of the housing sections 4 and 5. In order to allow only a clear position of the insert relative to the housing, only a further projection 23 is then provided, which fits into a positioning recess 24.

Guiding and fixing the insert within the housing can also be achieved in other ways, that is to say by cooperation of other projections and grooves in the relevant parts.
