Description: Desσr i Pt i on A Device for Wireless Switching of Illumination Bodies Technical Field The invention relates to a device for wireless switching of illumination bodies, above all in flats and other enclosed rooms. Background Art of the Invention Electrical illumination bodies in flats and in rooms inside buildings are mostly controlled by push-button switches. roughly called "switches", incorporated in the circuits of the leads installed to individual illumination devices. independently on the particular kind and design of the latter. Under the existing background art the illumination body switches, generally of push-button or sensor concept, are situated directly on the room walls in a close proximity of the door, thus within the reach of the entering person. For the illumination of pass-through rooms having several entrance doors, the problem how to switch the respective illumination body circuit as reguired in the room without the user being compelled to return to the same switch of his original entrance door, has already been solved in the world long ago. A currently used solution is so-called cross-coup1 ing of illumination body conductors, serving for inverting the current direction in the circuit without an OFF condition. The user simply switches ON and OFF the illumination of a room by a switch situated near any of several entrances, which can. however, be up to three only under the existing solutions. A constant and general limitation of the described insta11ation is a practica11y variab1e posi - tion of push-button switches near the door, so that, above all in darkness, the entering person is obliged to grope with his hand on the wall for the switch to be found. This is very inconvenient and impractical espe¬ cially in the rooms unknown yet to the entering person. There exist, no doubt, such illumination switches, which are fitted with glow-lamps. having a negligible power intake and signalling without interruption the switch position. This kind of switches with a constant light acts rather disturbing in a private residential room and is therefore mostly used in public or common corridors and staircases. In addition to the mentioned inconveni¬ ence there exists still another limitation of these switches, also in the case of their cross-σoupl ing, viz. they can only be used in the rooms in the walls of which such leads have already been installed. If, however, an alternative or cumulative switching of more illumination devices such as e.g. large chandeliers and lustres is required, additional parallel conductor lines with spe¬ cial switches are necessary. They are used e.g. for am¬ plifying the illumination intensity in rooms. Such in¬ stallations require mounting a large number of conduct¬ ors into the walls. Known are, no doubt, also the switches for exceptional illumination bodies conceived on the principle of a pocket-si-ae high-frequency wave generators with a fixed signal transmitted to a high-frequency receiver embodied in the illumination de¬ vice, e.g. for switching night lamps or emergency illu¬ mination bulbs. These are. however, distance switches analogous to the TV controllers etc, whose function can¬ not be integrated into standard illumination installa¬ tions of rooms intended for a general use, and that is why they are of an exceptional and individual applicabi¬ lity only. Disclosure of the invention The said inconvenience is substantially remedied by a device for a wireless switching of illumination bodies above all in flats and other rooms. the principle whereof is in that at least one door controller and at least one actuator are attached to at least one side of a door body, and in the door controller a high-freuqen- cy modulator with a transmitting antenna is fitted and connected with a code selector, further an actuator switch and a power source, while within the action range of the waves of the high-frequency modulator at least one performance unit is situated, containing a high-frequency demodulator with a receiver antenna con¬ nected with an analyzing member and a switching member, the latter being connected with the electric circuit of at least one illumination body. The device according to the invention enables.on the basis of a corresponding selection of a modulated coded signal, for which also the analysing member of the high-frequency wave demodulator in the performing unit has been preset, to switch ON and OFF by means of an actuator independently as well as in parallel several illuminating bodies in one or in several rooms. The actuator, which can be handled merely by a tipping with the upside of the fingers of one hand, is placed quite closely to the door lock and no illumination switch has to be blindly groped for in a darkness around the room door. The person intending to enter a room has a possi¬ bility of switching on the room illumination in advance and at the same time while opening the door, still before entering the room. To still improve the device efficiency, it is of advantage to place the door controller together with the actuator on both sides of the door body, preferably below the handle of the door lock. The actuator switch circuit can be combined with a circuit of an arresting member, consisting of a reed relay contact and a permanent magnet. The actuator can be designed as a con¬ ventional push-button switch or as a contact sensor with an analogous function. In the analyzing member circuit of the performance unit an ambient illumination pickup can be incorporated, disabling the performance unit if a sufficient daylight intensity is in the room. In the case that also a standard wiring for the illumination body controlled by a conventional push-buton is installed on the wall, it is possible to connect the performance unit instead of the conventional wall push-button, while the electromechanical function of the switch is maintained in combination with the performance unit. Depending on existing specific conditions, the high-frequency modulator mounted in the door controller can be a transmitter of RF, IR or UHF waves. Survey of pictures in the drawings The invention will be nearer explained by means of the drawings among which Fig. 1 presents the outer view of a door controller with an actuator below the door lock handle with the actuating position of man s hand, Fig. 2 a schematic view of the door controller assembly, Fig. 3 a schematic view of a door body with the door controller and actuator connected with an arresting member, Fig. 4 a schematic view of the performance unit assembly with an ambience illumination sensor. Fig. 5 a schematic view of the assembly from Fig. 4 connected with conventional conductors and with a standard illumi ¬ nation body switch, and Fig. 6 a schematic plane view of an installation of both-sides arrangement of the twin door controller in two connected rooms having several doors. Examples of embodiment of the invention The device according to Fig. 1 consists of a door controller 1_, mounted on the door body 2 close to the door lock 3. To the upper part of the door control 1_ an actuator 4 is attached and situated directly below the body of the handle 5 of the door lock 3. The actuator 4 is either a push-button switch of a simple make and de¬ sign with a return spring (not shown), or a contact sensor of a conventional make, fulfilling an analogous function. According to Fig. 2, the door controller 1_ forms an enclosed assembly, containing its substantial parts, being above all a frequency modulator 6 of an electronic type, fitted with a transmitter antenna 7 and further a code selector 8, whose function is providing for a signal code preset earlier. The high-frequency modulator 6 is substantially a wave transmitter with a local range. To the code selector 8 a switch 9 of the actuator 4 is connected, performing an analogouos funct¬ ion as if a conventional push-button switch or a contact sensor is used (not shown) as current components. To the code selector 8 a power source JK) is further connected, represented in the demonstration case by an electroche¬ mical battery, feeding power for the whole door control¬ ler 1_. According to Fig. 3 the circuit of the actuator 4 is connected with an arresting member i_l_, consisting of a contact ±2 of a reed-type relay, situated in the door body 2, and of a permanent magnet 13, situated in an op¬ posite position outside of the door body 2. The function of the arresting member 1_1_ as a whole is to disable the circuit of the actuator 4 when the door 2 is closed. This prevents any activating of the door controller i by an unwanted person from outside even if the door 2 is closed. The arresting member \Λ_ can be of any other de¬ sign e.g. having a direct connection (not shown) with the mechanism of the door lock 3. According to Fig. 4 still another substantial part of the device according to the invention is a performance unit 1_4, situated at any po¬ sition in the room to be illuminated, but anyway, within the wave range of the high-frequency modulator 6, situ¬ ated in the door controller 1. Said performance unit 14 consists of a high-frequency demodulator 1J5, repre¬ senting together with the receiver antenna 16 roughly a high-frequency wave receiver. Another substantial part of the performance unit 1_4 is an analyzing member 17. serv¬ ing for decoding of the signals from the high-frequency modulator 6, and whose function is transforming the code signal in an electric pulse for the switching member 18. The latter forms the last part of the performance unit 14 and its output is connected with a conductor 19 of an illumination body 20, into which it switches the feeding current by means of a triac member having a function of a two-way triode thyristor or of any other commutating element known in the electric technology. According to Fig. 5 the performance unit 14 is connected into a cir¬ cuit of a conventional line 19 to the illumination body 20. The use of a conventional push-button switch 21 si¬ tuated on the room wall is made possible by its connect¬ ing to the analyzing member 17. To the same member also the ambience illumination sensor 22 can be connected, responding to a preset illumination intensity in a given room and leaving the circuit of the analyzing member 17 disconnected and the illuminating body 20 OFF, if the natural illumination of the room is -just sufficient. The function of the device is apparent from Fig. 6. The person entering the room 23 e.g. through the door 2 activates, when opening the door, by the backhand one of the twin actuators 4 tuned up for the signals of a modulated code A1-A2. by the fact of which activation that actuator 4 has been used as the main one, and this signal results in a wave field in the corresponding door controller l . The said coded signal is received by the receiver antenna 16 of the frequency modulator 15. in the performance unit 14, and it is transmitted to the analyzing member 3/7, from which the pulse is further transmitted to the switching member 18., which will switch the circuit of the illumination body 2-Q, situated in the room 22- And then, when this person leaves the room through the same door 2 , he will use for switching -off the illumination body 20. the same actuator 4 from the twin assembly on the outer side of door 2 , thereby defined as a main actuator. The actuator 4. defined as a secondary one, would represent in the given situation one part of the twin actuators for code signals Bl - B2 and the said person in the room 2_3 would use it alterna¬ tively only if he wants to switch the illumination body 20 without leaving the room 22. and without opening the door 2 . By such an alternative use of the system the signal field Bl or B2, as may be, is generated, and the analyzing member 3/7 transmits in the way described above a pulse for the switching member 18 to cut the circuit of the illuminating body 2Q_ . The same effect can be obtained also when entering the room 22 through other doors 2ϋ, 2h or 2c, and the other way about, when leav¬ ing the room, by means of code signals C1-C2, D1-D2, El- E2, F1-F2, G1-G2, H1-H2, 11-12 and J1-J2, which also comprises the entering or leaving through the door 2ct into another room 24. with illumination bodies 20a, 20b and 20c. connected to the analyzing units 14a, 14b and 14c. The same is valid also when using the door 2c. Duplicating the door controllers 1 and actuators 4 in twin assemblies is not limiting and even more such door controllers 1 and actuators 4 may be installed on both sides of the doors 2 , 2a, 2b, 2s and 2d.. It is possible to switch by them even more illuminating bodies fully deliberately even in a larger number of rooms, which depends on a corresponding selection of a code signal . The system can also be used for a timed illumination of the connected rooms by incorporating a timer into the circuit of the analyzing member 17, or into the switching member lg., which is purposeful when only pas¬ sing through said rooms. Industrial applicability The device according to the invention can be used practically in all enclosed rooms and spaces not only in flats, hotel rooms and hostels, but with the same efficiency also in offices and public buldings, in industrial premises, hospitals aand schools. They can be adapted also for the use on doors fitted with various types of locks including those electronically controlled e.g. by means of code cards or similar elements.
