Description

Electronic lic} ts..gnalgee description.

Various devices and systems are known in the art, which cause a light signal to be given at intervals.

These devices usually work from a central control system, from which certain predetermined call channels are controlled via key switches can. With the help of relays, current signals of a predetermined voltage are transmitted via these given to the preselected lines, which are then put into connected lamps on the intended Place to be converted into light signals.

These devices or systems are, however, the scope, type and not suitable for simpler use in terms of price.

The subject of the application does not have these disadvantages and allows them Due to its design, the simple implementation of a short-term release, for example a ringing signal in a sequence of light signals, the duration of which, chronological sequence and number of the functioning of the device and, among other things, of Dimensioning of the RC circuits arranged therein is dependent.

Above all, the device is also well suited for self-help as a locally easily changeable signal generator for the hard of hearing in the personal area to be used in the apartment. Furthermore, as a simple signaling device for multi-storey buildings Apartments, as a signal transmitter for advertising lights, etc.

A special use of thyristors in a coupled functional arrangement with two electronic clock generators allows the simplified structure of the device for the specified area of application.

A universal application results from the fact that by appropriate Circuit coupling of the individual function groups a direct connection option the two areas of tension that exist everywhere in apartments; although to Control of the device, its connection to an existing bell network, in the voltage range of approx. 3 - 15 volts alternating current, as well as for power supply of the device and delivery of corresponding power impulses for conversion into light signals, its connection to the existing lighting network. Generally a voltage of 110 or 220 volts alternating current.

Mains connection via inputs 2 and 3. Control of the device via inputs 14 and 17. The device can can be controlled via this. These control inputs are parallel to the bell 12 and are connected to the two primary coil ends of an input transformer 20. This causes a galvanic separation between those working in puncture coupling Device circuits - on the one hand - and the one outside the device in the area of the Control circuit of the bell system located at low voltage.

When you press the bell button 11, the circuit is now an approximately existing bell 12 and at the same time the circuit of the parallel applied Input transformer 20 closed. This is done accordingly on its secondary side its conversion ratio is taken from the converted input signal and a thyristor 4, which together with a thyristor 5 forms a thyristor flip-flop.

Thyristor 4 as one side of the trigger stage, now takes over with the positive half-wave of the current impulse, the signal applied on the secondary side ignites i.e. switches on the supply voltage - from 21 and starts the device with it. Here, first of all, the two clock generators 8 and 9.

Clock generator 8 causes the ignition in each case at its own frequency a thyristor 10 which is in series with the primary coil of the mains transformer 22. There he only works with the positive half-wave of the alternating voltage and when arriving the same switches through and then extinguished again. In this way, it becomes a quenching element saved up; on the other hand, he can switch through his full power. This in frequency the applied AC voltage and as long as the trigger pulse from the clock generator 8 is pending on the grid of this thyristor 10.

In this way, the connection points 6 and 7 can be connected Signal transmitter e.g. lamps 16 are made to light up at intervals.

The size of the interval is determined by the duration of the pulse from clock generator 8, as well as from the clock pause resulting when it is switched back.

The switching cycles described are repeated until the in his effect delayed clock generator 9 comes into operation. i.e. when switching back (Transistor 23 blocks) with the trailing edge of the switch-off pulse via capacitor 13th the thyristor 5 ignited. The thyristor stage tilts back, the thyristor 4 extinguishes, whereby a shutdown of the supply voltage and thus an automatic shutdown of the entire device. The thyristor stage is tilted back by means of ignition of the thyristor 5 made via anode control with a capacitor 18, wherein this must be so large that the holding current of the thyristor 4 by the charging current of the capacitor is withdrawn.

Since now the second thyristor 5 of stage 1 is not in the holding current range operated and also extinguished, i.e. itself in its practical effect switches off, the entire Werät is at the lowest despite constant operational readiness Power consumption brought.

To be used as a locally easily changeable symbol especially for To be able to be used for the hard of hearing and deaf, iwt the device with different Provide connecting plugs (illustration II). For connection to the lighting network with a (Schuko) plug 24 as a plug connection according to regulations. on the other hand for easy connection of a signal transmitter e.g. for an easily changeable one Table or stand lamp, with a plug-in coupling 25 (Schuko coupling), as well as for easy connection to a bell box that can be attached anywhere in the room, therefore with Ig a simple bell plug, similar to that of simple connections for small low-voltage lights.

Since the connector plug connections are essential in terms of type and size If there are differences, there is a guarantee and security against confusion.
