The remote control 4 contains batteries 18, connected through a switching unit, which is one or a set of electrical buttons, to the input (or inputs) of the unit 20 for generating control signals of the radiating element 21/1 /. The unit 20 may have a different design. For example, in the form of an encoder / 1 /, at the output of which a packet of pulses is formed, time intervals between

It can be an LED when the remote control 4 is connected to the receiver unit 5.

The receiver unit 5 includes a radiation receiver (when working with optical radiation, a fB3 receiver, and when working with radio emission, a receiver) .If the control unit 4 receives a burst of pulses from the encoder 21, then the decoder 5 includes 1/. If the remote control unit 4 formation unit 20 is made in the form of a pulse generator or a sinusoidal signal, then in block 5, respectively, should include a pulse signal amplifier or amplifier with a narrow-band filter tuned to the generator frequency.

The drawing shows an embodiment of the controlled time delay unit 6. It contains a single vibrator 22, the input of which is connected to the output of unit 1 and to the input of the O installation of the integrator 23. The output of the single vibrator 22 through the low-pass filter assembly 24 is connected to the first input of the comparator 25, the second input of which connected to the output of the integrator 23, the signal input of which (not shown in Fig. 1) is connected to the corresponding power bus of this integrator. The output of the comparator 25 through the pulse former 26 is connected to the first input of the element ШЩ 27, the second the input of which is connected via the pulse shaper 2S to the network bus. The output of element 27 is connected to the installation input at 0 m of trigger 29, the input of which 1 is connected to the input of unit 1. The output of trigger 29 through the pulse former 30 is connected to the output of block 6. Filter unit 24 can be made in the form of an integrating circuit parallel to the resistor in which the diode is connected by a cathode to the capacitor of the circuit. Pulse shapers 26, 30 can be made in the form of differentiating chains.

The device operates as follows. When the mains voltage appears, trigger 10 is set to O. At the same time, the And 13 element is locked, the key element of block 2 is also locked. When you quickly press and release (the time the button is pressed for no more than 0.5 sec) the buttons of the switching unit 19 of the remote control 4, voltage is supplied to the control input of the remote control from the batteries. In this case, a signal packet appears at the output of the forming unit 20, causing radiation to appear at the output of the radiating element 21. The receiver unit 5, which is transmitted through the radiation channel (optical or the radio channel) is connected to the remote control 4, generates a signal at its output, causing the output of the former 7 at the time of pressing the button on the remote 4 logical 1. When you release the button on the remote 4 at the output of the former 7 is set to logical 13. At the output of the allocation circuit 9 a pulse appears, the pulse sets at the output of the trigger 10 1. At the same time, the And 13 element is unlocked. A sinusoidal voltage is supplied to the input of the driver 15 from the network bus.

15 a meander with steep fronts is formed. At the output of the shaper

16, short pulses appear that coincide in time with the leading and trailing edges of the output signal of circuit 15. For each pulse from the output of the shaper 16, the code from the outputs of the counter 11 is rewritten to the reverse counter 12. The reverse counter 15 is turned on for operation in the subtraction mode. the output of the generator 17, the binary number at the output of the counter 12 is reduced by 1. The pulse rate of the generator 17 is set so that the maximum binary number written to the counter 12 is reduced to O for half signala.V network time when the binary number is equal to O, at the output of the counter 12 a pulse which through the open AND gate 16 is input to monostable 22 unit 6 controlled time delay. The duration of the pulses at the output of the single-shot 22 is provided longer than the half-period of the network signal. In this case, if there are pulses at the input of the single-shot 22, a low-level constant voltage is established at its output, which is fed through the low-pass filter assembly 24 to the first input of the comparator 25. The filter assembly 24 has a different time delay: large (2-5 sec) with an abrupt decrease voltage at its input and small (not more than 0.1 sec) with an abrupt increase in voltage at its input. At the moment of arrival of the impulse to the input of zeroing of the integrator 23, a low level voltage is established at its output, which then begins to increase. At the time when the voltage at the output of the integrator 23 is equal to the voltage at the output of the filter unit 24, the comparator 25 is also triggered by its output signal output; Pulse generator 26 a pulse appears, arriving at the first OR 27, at the second input of which from the pulse shaper 28 connected to the bus network signal, the pulses and time coincide with the network signal goes through O. When a pulse arrives from the output of unit 1 to the input of the 1st triyof 29, it is set to 1 at its output. When a pulse arrives from the output of element 27 to the input of the O setting of trigger 29, it is set to 0m at its output. At this point in time, the output of the shaper 30, a pulse appears, upon receipt of which the element is unlocked in block 2 and the mains voltage is applied to the lamp 3 of the lamp. The time delay between the pulse from the output of block 1 and the pulse from the output of shaper 26 is greater, than the voltage at the output of the filter assembly 24 is greater. After the appearance of pulses at the output of block 1, it slowly (for 2-5 seconds) decreases. When it reaches a low level, the time delay between these pulses turns out to be quite small (5-10 μs). Temporary position. the pulse from the output of block 1 relative to the beginning of the half-cycle of the network signal depends on the code at the outputs of the counter 11. The larger the binary number, the farther the pulse is from the beginning of the half-period. At the maximum code, the pulse at the output of block 1 coincides with the end of the half-cycle. At the same time, the key element does not have time to open and the lamp 2 turns off. With a minimum code (zero code) at the outputs of counter 11, the pulse from the output of block 1 is separated from the beginning of the half-period by a short time (of the order of 100 μs) .In this case, the key element turns on almost the entire period of the network signal and lamp 2 provides maximum luminous intensity.

A circuit consisting of a shaper 28, an element 27, and a trigger 29 is necessary in order to prevent the pulse from the output of the shaper 26 from getting to the next half-cycle in operation with a high voltage at the output of the filter assembly 24 (otherwise, the entire device will malfunction).

The introduction of a controlled time delay unit 6 leads to the fact that when the device is turned on, lamp 2 slowly enters the glow mode, which is pleasing to the eye, and also significantly (by tens to hundreds times) increases the lamp life (the lamps burn out mainly at the moment of switching on due to the low resistance of the coil in the cold state). 1 1 2 1 When you press and do not release the SHC | button 19 of the remote control 4 for a long time (more than 1 second) {UH% output of the former 7, logical 1 appears (during the time of pressing the key). It should be noted that the output signal of trigger 10 at atom does not change, since circuit 9 responds only to an impulse (quick pressing and depressing the button 19). Element And 8 is open and from the output of the former 15 meander, through the element 8, the counting input of the counter 11 enters, which leads to a change in the code at its outputs. this temporary position of the pulse from the output of block 1 relative to the beginning the half-period of the network signal starts to change and the radiation power of the lamp 2 also changes. When the second button is pressed and released sharply 19, circuit 9 generates a pulse at its output, which sets the state of the trigger to 0 m at the output of trigger 10. This element TG 13 is locked. pulses come from block 1, and therefore the key element of block 2 is locked. Filter 24 quickly recharges to a high voltage level (Quick reloading of the filter allows you to re-enable lamp 2 almost immediately after turning it off). Introduction to the device of new elements and connections provides: remote control of the lamp, slow, pleasant to the eye, the inclusion of lamp lamps, increasing the life of lamp lamps.
