Utility model description.

"Lighting device with a variety "Lamps connected in series or in parallel".

In general, lighting devices for rooms Halls, passenger rooms in vehicles, e.g. in buses, in the way listed that a large number of lightbulbs be connected in parallel, whereby it is possible by means of. Double ** beaw. Triple switch for all lightbulbs to be switched on together or partially.

For the necessary weak lighting while driving does not give the driver any rüclrblendui ^ and therefore an increased one Driving safety guaranteed, so as to save electricity, it was suggested to connect the lightbulbs in series and then doing lightbulbs correspondingly less powerful too use· - '

The fact has a disadvantageous effect on this electrical system from the fact that: if one light bulb fails - all of them fail, because the power supply is interrupted.

In order to remedy this problem, it has already been suggested that several strings of lightbulbs connected one behind the other

to connect in parallel so that "in the event of failure, a bulb then the relevant strand fails completely while the other pears continue to burn. "

But here, too, the disadvantage is that Bel become defective of a pear one side of the eäuna, wp the "relevant strand relocated .1st, ..not, is illuminated anymore.

In contrast, "the! Inflation makes it a task To create lighting equipment that is both is economical in consumption, i.e. with approximately the same amount of light generation, "one" consumption is much lower than all the others Systems with the same Lieht generation, as well as the IT disadvantage avoids that if a pear becomes damaged Whole strands of light or even all of the light bulbs too fail.

The new facility is intended primarily for passenger compartments of buses, W _0, the lighting during ao only in a small lichtstär & D driving; ll to the driver. not to hinder.

Such lighting devices have hitherto either As described above, executed in parallel connection, with Bir.Een switched on only occasionally during the journey in order to avoid a greater amount of light, or but mainly laid out in series, so in the case of lower light, it would be largely / electricity at the same time to save, although all the pears are burning.

Compared to the well-known lighting, the emulation to the task, for such passenger compartments a To create a system in which it is possible, with the help of a simple device switch all lightbulbs full

to switch on, as well as, for example, only half of the lightbulbs, in addition, however, a circuit of the pears in the way

it becomes possible that the lightbulbs are partially parallel and are partially connected in Heihe, whereby on the one hand elne Significant power savings are achieved, on the other hand, there is security that the system in its entirety continues to burn and only the defective Birna fails, beyond that, however, it is precisely the wüjischte, brightness that is generated, which on the one hand does not disturb the driver while driving the vehicle, on the other hand "sufficient" lighting of the passenger compartment made possible. . '

The hiring consists in the fact that a larger number of lamps on two different parallel lines (e.g. one. plus and two lnus lines) alternately or in groups: e "ange ·! · are closed and a multiple switch, for example, Irei aehgerät- • switch, is provided by its - .. respective conversion the lamps can be partially switched on and off -bezw. "in groups can be switched one after the other.

One or more light bulb strings connected in this way can be used be provided.

The firing can be carried out in various ways.

It is in the drawing in eLiier embodiment form, for example -. '. in shown in a Sehaltschema.

Fig. 1 shows the position of the switch vsiö. the connection of the lamps, with all the examples shown - lightbulbs

In Äbb.1 the triple appliance switch 1 iät such with the beispw. Gezeiehnefen bulbs six 2,3,4,5,6,7 gejschaXtet that jevfeils erselbenbeispw ä every six bulbs with its contact a to a · xa £ L. Plus line b lie, while their contact c alternates between minus lead line d and line e

connected, i.e. the bulbs 2, 4, 6 are parallel connected to lines b and d while the lightbulbs 3,5,7 are connected in parallel to the lines Td u.d, e.

The total consumption of all pears results from the sum the, individual consumer, i.e. if each bulb consumes too watts, for example, the total consumption is Soo watts. The pears burn at full strength.

In Fig.2 there is another position of the triple device switch 1 shown, in which only the lines b ande are connected to the network. It burn z. Zt * only half the Incandescent bulbs, namely 3.5 * 7, with full brightness at the normal consumption of 100 watts each. The total consumption is therefore 300 watts.

In Fig. 3 the third circuit option is shown, in which the triple device switch is only connected to lines d and e, with the previous Mu must line now being connected to the positive pole.

However, line b is not required in this circuit slain ,. as for example the line d in the case of Fig. 2, but them. is about the lightbulbs nit in the circuit

Through this circuit, "two pears are now connected together to form a group, aläo the pears 2, 3 form one group, the pears 4, 5 the second group, the pears 6, 7 the third group ...

If lamp 3 fails, lamps 2, 4 to T are still switched on. If the lamps 3, 4, 5 fail, the lamps 2, 6, 7 are still "connected to the Hetzr, since in the event of this" over the Lamp 7 the circuit to lamps 2,6,7 remains closed, which are then also connected in series. Depending on the failure one or more lamps esp. Groups Brennex the left permanent lamps with different voltages. \

It is possible to add even more lamps as part of the invention to connect and, if necessary, to connect two adjacent parallel lines to the same plus and ISinus parallel lines.

Instead of a lever switch, a rotary switch can also be used, whereby if necessary: two positive lines and a single negative line for the. Lamps can be provided ^. . ■
