The invention relates to lighting and can be used for dynamic lighting of various cultural and entertainment events.

Known lighting device programmed the automatic closed-loop. This device allows you to get some lighting effects, for example running lights, pairwise switching lamps and others [1] .

Known lighting device designed to create different light effects: running lights with different number of simultaneously enabled lights, moving lights (reverse running lights), as well as to have effect when the lamp is lit up, and then turn off [2] .

The disadvantages of the known lighting devices are, firstly, the discrepancy between the received light effects with the rhythm of the movements of the participants, and secondly, the monotony and the ili feels latent defects lighting effects generated by the device.

The invention consists in improving a spectacular effect by introducing a relation between the light effects created by the device, with the rhythm of the movements of the participants, using the Doppler effect on the ultrasonic frequency.

As the light effects created by this device, is controlled directly by the participants of the action, they correspond to the dynamics of their movements, which significantly increases spectacular effect.

The basis of the synthesis of light effectlively fluctuations, resulting from the reflection of ultrasound from moving objects, i.e., the participants of the action.

For the introduction of the connection between the light effects created by the device, and rhythm of the movements of the participants in the room is installed a few (depending on room size) transmitting and receiving ultrasonic transducers. Transmitting transducers connected to the generator of ultrasonic vibrations, and outputs the receiving transducers are connected to the allocation and processing of the Doppler signal, consisting of an input amplifier, mixer, low pass filter, amplifier Doppler signal, the compressor, the output of the circuit connected to the inverter frequency - voltage, the signal of which is used to change the oscillation frequency of the clock pulses, the output of which is connected with a clock managing input programmed lighting switch based on a shift register with feedback, the output of which is connected to the lamps of the first group. In addition, the output of the circuit selection and processing of the Doppler signal is connected group of bandpass filters whose outputs are connected to the control circuit of the lamps of the second group, consisting of I, to the outputs of which are connected triac amplifiers lamps of the second group, the outputs of the control circuit connected to the lamps of the second group.

The drawing shows a block diagram of the lighting device.

The device comprises a generator of ultrasonic vibrations 1, transmitting ultrasonic transducers 2, the receiving ultrasonic transducers 3, the input amplifier 4, a mixer 5, the low pass filter 6, power Doppler signal 7, the compressor 8, four bandpass filter 9, the detectors 10 bandpass filters, the filters 11 detectors and the Schmitt trigger 12, the decoder 13 binary code decimal 13, sixteen, Sumitomo-photon-coupled amplifiers 14, lamps of the second group 15, power supply 16, the inverter frequency - voltage 17, generator clock pulses of voltage-controlled programmed lighting switch 19 clocked managing input, the lamps of the first group 20.

Electrical oscillations from generator 1 serves to transmit transducers 2, which excite ultrasonic waves in the surrounding space. Reflected from various moving and stationary objects ultrasound is converted into electrical oscillations foster change the possible differential Doppler frequency of the signals of the higher frequency, educated radiated oscillations and vibrations reflected from moving objects. To the mixer 5 is supplied as the voltage of the generator 1. The mixer device used conventional diode mixer. Further, the signal from the mixer 5 is supplied to the lowpass filter 6, which does not flow in the Doppler signal amplifier 7, the voltage of the higher frequency from the generator 1 and the input of the amplifier 4. The Doppler signal from the lowpass filter 6 is amplified by the amplifier Doppler signal 7. The compressor 8 is to maintain approximately the same signal level at the output of the circuit selection and processing of the Doppler signal. Since during operation of the device the distance between the ultrasonic transducers 2 and 3 and the participants can change the voltage of the Doppler signal at the output of amplifier 7 will also change. In the device used compressor, consisting of amplifier, controlled voltage, and the detector output voltage, an output connected to the control input of the amplifier.

Compensated Doppler signal is fed to the Converter frequency - voltage 17, the signal from which is applied to the control input generator is premirovannogo lighting switch 19, the output of which is connected to the lamps of the first group 20.

In addition, the compressor 8 is connected to four bandpass filter 9. The spectral Doppler signal, the selected filters 9 are detected by the detectors 10. Pulsating voltage detectors are smoothed out by the filters 11 and fed to the Schmitt trigger 12, needed to align the analog outputs of the filters 11 detectors with digital inputs of the decoder 13. The signals from all four outputs of the Schmitt trigger is fed to the decoder 13 binary code decimal 13, each of the sixteen outputs of which are connected Sumitomo-photon-coupled amplifier 14, which is loaded on my lamp, the second group 15. Items 10-14 form a control circuit of the lamps of the second group 15.

Svetadenisenko the device works in the following way:

If the receiving transducers are ultrasonic waves reflected only from fixed objects, then the output of the mixer 5 is no signal due to Doppler frequency shift of ultrasonic vibrations. Thus, there are no signals at the outputs of filters 9. At the input of the decoder 13 has the code 0000, therefore burning the first of the lamps 15. Since strain is; accordingly, the slowest switch lamp 20 programmable switch 19.

If within range of ultrasonic transducers are moving objects, then the output of the mixer 5 is the range of Doppler frequencies, which is divided bandpass filters 9. Then at the input of the decoder will be some code combination and it will be lighted lamp of the lamps of the second group 15. Inverter output frequency - voltage 17 is a voltage proportional to the speed of movement of the objects, i.e., participants ' actions. So if you increase the tempo of the movements of the participants of the action will be an increase in the frequency of the clock generator 18, and as a result will increase the switching speed of the lamps of the first group of programmable switch 19 lighting. Thus, if the subject is moving rapidly, there will be a transition from the lit lamps "quiet" channel up to the lighted lamps "fast" channel and will increase the switching frequency of the lamp programmable light switch.
