Description

Technical field
The invention relates to devices for wireless switching of lighting devices, for example, in apartments or other enclosed spaces.

State of the art
Electric lighting devices in apartments and rooms of buildings are mainly controlled by manual switches, colloquially called "switches", included in the supply wires circuits connected to each lighting device independently, taking into account the peculiarities of their design. With the current level of technology, switches, mainly keyboard or touch, are located on the walls of rooms in the immediate vicinity of the doors within the reach of an incoming person. To illuminate the passage rooms with several entrance doors, the existing problem of switching the circuit of the corresponding lighting device without returning the user to the same switch near the door that he entered was solved in the world long ago. The currently used technical solution is called a cross-switch of the circuits of lighting devices, serves to switch the direction of the supply circuit and does not have the "Off" position. The user simply turns on or off the lighting of the room with a switch located near any of several entrance doors, which, however, can be no more than three when using this technical solution.

 One general limitation of the described technical solution lies in the indefinite location of the key switches near the door, so that, among other things, an incoming person is forced to look for a switch in a dark room, fumbling along the wall with his hand. This is very inconvenient and impractical, especially for people first entering an unfamiliar room. Of course, there are switches that have built-in light bulbs of low power consumption, which serve to continuously illuminate the position of the switch. These types of continuous-light switches can be annoying in living rooms and are therefore mainly used in common corridors or stairwells. In addition to the inconvenience mentioned, there is another limitation of these switches also in the case of their cross-switching, since they can only be used in such rooms, in the walls of which the corresponding wiring was laid. However, if alternative switching of more lighting fixtures is required, as may be the case in large chandeliers, it becomes necessary to lay parallel wires and use special switches. They are used, for example, to control the intensity of light in rooms. Such devices require the installation of a large number of wires in the walls. Of course, switches are also known for special lighting devices based on the principle of using small-sized high-frequency wave generators with a constant signal transmitted to a high-frequency receiver integrated in a lighting device, for example, for night lighting or emergency lighting. However, they are remote switches similar to the TV remote controls, which cannot be combined with standard room lighting fixtures intended for general use, and therefore are used only for special and individual use (see, for example, EPO 0153467 A1 of 09/04/1985) .

Description of the invention
This inconvenience is significantly reduced by a wireless switching device for lighting devices in apartments and other enclosed spaces, the principle of which is that at least one door controller and at least one starter are installed on at least one side of the door , and a high-frequency modulator with a transmitting antenna is installed in the door controller and connected to a code selector, then to a starter and an electric energy source, while in the wavelength range, high -frequency modulator is arranged, at least one actuating device comprising a high-frequency demodulator with a receiver antenna connected to the analyzing device and a switch which is included in an electrical circuit, at least one lighting unit.

 The device according to this invention allows, based on the appropriate choice of a modulated code signal, for which an analyzing device of a high-frequency demodulator signal is installed in the actuator, to turn on and off several lighting devices in one or several rooms with the help of a starter, separately or jointly. The starter, which can be controlled by switching with the fingers of one hand, is located next to the door lock, which eliminates the need to grope it in the dark near the door to the room. A person who intends to enter the room has the opportunity to turn on the lighting of the room in advance and along with opening the door in front of the entrance to the room.

 To further improve the efficiency of the device, it is better if the door controller is placed together with the starter on both sides of the door, preferably below the door lock handle. The starter circuit can be combined with a limiter circuit, consisting of the contact of a reed switch and a permanent magnet. The starter can be designed as a regular key switch or as a contact sensor with analog functions. An ambient light sensor can be integrated in the analyzer circuit of the actuator to turn off the actuator if there is sufficient daylight in the room. In the case when there is wiring in the wall, designed for the use of a standard keyboard light switch, it is possible to include an actuator in the circuit instead of a conventional wall keyboard switch, while the electromechanical functions of the switch are supported in combination with an actuator. Depending on the specifics of the existing conditions, the high-frequency modulator installed in the door controller can be a transmitter of RF, IR or UHF waves.

Examples of the embodiment of the invention
The device in figure 1 consists of a door controller 1 mounted on the door 2 near the door lock 3. In the upper part of the door controller 1, a starter 4 is installed and located directly under the handle 5 of the door lock 3. As a starter, either a key switch of a simple design and versions with a return spring (not shown), or a conventional contact sensor that performs analog functions. In figure 2, the door controller 1 is a closed device containing the main parts, first of all, an electronic type frequency modulator 6, with a transmitting antenna 7 and then a code selector 8 connected, the functions of which are to predetermine signal coding. High frequency modulator 6 is nothing more than a transmitter for the local radiation range. Connected to code selector 8 is switch 9 of starter 4, which performs the analog functions of a conventional key switch or contact sensor (not shown). An energy source 10 is also attached to the code selector 8, which is presented for demonstration purposes in the form of an electrochemical battery supplying energy to the entire door controller 1. FIG. 3, the starter circuit 4 is connected to the limiter 11, consisting of a reed contact 12 located in the door 2, and a permanent magnet 13 located on the opposite side outside the door 2. The limiter 11 functions to turn off the starter 4 circuit when the door is closed. This prevents the door controller 1 from starting up by an undesirable person from the outside when the door 2 is closed. The limiter 11 may have any other design, including with direct contact (not shown) with the door lock mechanism 3. Figure 4 shows another important part of the device, the actuator 14, located anywhere in the room that needs to be illuminated, however within the radiation range of the high-frequency modulator 6 located in the door controller 1. This actuator 14 consists of a high-frequency demodulator 15, which together with the receiving antenna 16 represents a high-frequency receiver otnyh waves. Another essential part of the actuator 14 is an analyzer 17, which is used to decode the signal from the high frequency modulator 6 and transmit the code signal in the form of an electrical pulse to the switch 18. This switch is the last part of the actuator 14 and its output is connected to the wire 19 of the lighting device 20, in which he switches the supply current using a triac having the functions of a symmetric triode thyristor or any other switching element known in e ektrichestva. In Fig. 5, an actuator 14 is included in the circuit of a conventional line 19 of the lighting device 20. The use of a conventional key switch 21 located on the wall of the room becomes possible when connected to an analyzer 17. An ambient light sensor 22 reacting to the same analyzer can also be connected the intensity of the lighting available in this room, and disconnecting the analyzer circuit 17 and the lighting device 20, if the natural lighting of the room is sufficient.

 The operation of the device is obvious from Fig.6.

 A person entering room 23, for example, through door 2, entering the door, launches one of the dual starters 4, switching of which leads to the signal code A1-A2, which serves as the main trigger for the corresponding door controller 1 emitting a high-frequency signal. This encoded signal is received by the antenna 16 of the frequency demodulator 15 in the actuator 14 and transmitted to the analyzer 17, from which the pulse is transmitted further to the switch 18, which will turn on the circuit of the illuminator 20 located in room 23. Then, when this person leaves the room through the same door 2, it uses the same starter 4 of the dual device on the outside of door 2 to turn off the illuminator 20, defined as the main starter. The starter 4, defined as secondary, in this situation represents the part of the dual starter that supplies the code B1-B2, and the person in room 23 can only use it if he wants to switch the illuminator 20 without leaving the room 23 and without opening the door 2.

 Using this alternative starter can lead to the generation of a signal field B1 or B2, and the analyzer 17 will transmit a pulse in the manner described to the switch 18, breaking the circuit of the illuminator 20. The same effect can be achieved if you enter the room 23 through other doors 2a, 2b or 2c or exit it using the code signals C1-C2, D1-D2, E1-E2, F1-F2, G1-G2, H1-H2, 11-12 and J1-J2, also used when entering or exiting through door 2d in another room 24 with the illuminators 20a, 20b and 20c located therein associated with the analyzers 14a, 14b and 14c. The same holds true if a door 2c is used. The combination of door controllers 1 and starters 4 is not a limitation and more door controllers 1 and starters 4 can be installed on both sides of doors 1, 2a, 2b, 2c and 2d. It is possible to switch with their help also a larger number of lighting devices and even in a larger number of rooms, which depends on the appropriate choice of code signals. The system can also be used for short-term lighting of rooms by setting a timer in the analyzer 17 or in the switch 18, which makes sense when you only need to go through the room.

Industrial application
The device according to this invention can be used in almost all enclosed spaces and spaces, both in apartments, hotel rooms and hostels, and, with no less effect, in offices and public buildings, industrial halls, hospitals and schools.

 It can also be adapted for use on doors with various types of door locks, including electronic ones, controlled, for example, using a code card or similar elements.
