The present invention relates to a multi-color lighting conversion control device, in particular, to receive a sound signal, such as songs, music, etc. in a place for producing a variety of indoor atmosphere is separated by a plurality of frequency bands to change the lighting of a plurality of colored lights In addition, the present invention relates to a multi-color lighting conversion control device that enables the brightness of a corresponding lamp to be automatically changed according to the volume level of the separated frequency band.

Conventional multi-color lighting fixtures control the conversion of the multi-color lighting by simply using the lamp flashing circuit of the sequential flashing method, or by flashing the light fixture in a bimetal contact method using the heat generated from the filament inside the lamp, such methods are in a certain form It is a lamp flashing method that changes periodically and repeatedly within a limited time, which makes you feel bored with a short flashing cycle and monotonous lighting effects. Recently, in order to solve the monotony and boredom of such lighting effects, a special memory lighting method using a semiconductor memory device is used. Although the manual control method using the controller or artificially operated was used, the special lighting controller was expensive due to the high cost of manufacturing and installation. There is the trouble to work There was a problem.

As a device for solving this problem, as shown in FIG. 3, a volume response lighting device which receives a sound signal and selectively flashes a lamp in accordance with the sound level of the sound signal, that is, the intensity of the sound, is used. 70400) has been proposed, in which the device of the present invention is an attenuator (3-5) of a volume response means (10) after a voice signal input to the microphone (1) is amplified to an appropriate level through an amplifier (2). The lamp signal 7-9 is turned on by the lamp driving unit 6 by separately outputting a voice signal according to the internally set condition, and setting the operation of the volume response means 10. Is determined by the switch means 11.

The conventional volume response lighting device is to further distinguish the various input sound signal by the intensity of the sound, and to flash the lamp corresponding to the intensity of each sound, further than the conventional simple control method. According to the change of the visual effect of the lighting can be achieved, but this is only by the sound intensity between the high and low of the sound, by simply flashing the lamp by expressing only a part of the various sound signals can be expressed in color to obtain a sufficient visual effect I can't.

In addition, as another embodiment of the conventional volume response lighting device (Japanese Laid-Open Patent Office 61-39599), as shown in FIG. 4, a low, medium, and high range of voice signals input using three filters are shown. The low and mid ranges are set to 300Hz, the mid and high ranges are set to about 3000Hz, and when the sound reaches the corresponding frequency, only the lamp flashes and the brightness of the lamp can be adjusted by adjusting the time-varying resistor. There was something to be.

In another conventional device, a voice signal input to the microphone 27 is converted into an electrical signal and amplified and supplied to the filters 24 to 26 to separate low, medium and high sound ranges, and the variable resistor VR1 -By setting the volume in advance by the control of VR3), if there is a voice signal through the filter 24-26, the Dyistor (SCR1-SCR3) is turned on to selectively select the bass, middle and treble lamps 21-23. It is supposed to flash.

The conventional volume response lighting device according to another embodiment of the present invention provides a more diverse visual effect by controlling the blinking of the lamp by dividing the pitch of the sound, that is, the input voice signal by frequency range, unlike controlling the blinking of the lamp according to the intensity of the sound. To get it.

However, the volume response lighting device is also designed to distinguish the height of the sound by the filter, and to simply flash the corresponding lamp, and cannot visually express the change due to the intensity of the sound, and also receives a voice signal from the outside. There is a problem that the input means is limited to the mitrophone 27 and its use is limited.

Therefore, the present invention receives the external sound signal to various input means, such as a volume device or a microphone to solve the above problems, and separate into a plurality of predetermined frequency bands to distinguish the height of the sound by the number of multi-color lighting, etc. The separated sound signal extracts only the correct predetermined frequency band again through the equalizer circuit to light up the corresponding lamp, and the separated frequency is the phase control circuit so that the conduction angle of the lighting power source depends on the frequency level of the sound signal. By varying the intensity of the sound, the brightness and the lighting time of the lamp are automatically changed by the intensity and weakness of the sound volume, so that a number of color lights, a large number of tones with different natural frequencies, and the volume level of each tone can be obtained. Various colors of light are combined with each other to make it colorful and diverse To provide a multi-color one trillion people conversion control apparatus which can produce it in the object of the present invention.

In order to achieve the above object, the present invention provides a signal input unit that receives and adjusts and amplifies an external voice signal through a microphone, an audio signal selection unit for selecting an audio signal from the microphone or an audio device, and the sound signal selection unit. A sound signal control unit for adjusting the size of the sound signal selected in the; A frequency separation unit for separating the sound signal adjusted by the sound signal control unit into a plurality of predetermined frequency bands, and accurately extracts the frequency divided into the plurality of bands to a predetermined frequency And a phase selector for amplifying, a signal amplifier for amplifying the extracted plurality of frequencies of the predetermined band to a predetermined level, and a phase for automatically adjusting the brightness of the lamp according to the frequency level by controlling the phase of the output signal of the signal amplifier. And a drive circuit for turning on a multi-colored lamp by an output signal of the phase controller. It has been made.

Referring to the effect of the present invention made as described above in detail.

First, the external audio signal and the tape (TAPE) from the sound signal selection unit (b) through the microphone (MIC) of the signal input unit (a) with the constant voltage rectified by the power supply unit (i) supplied to all circuits and devices. When one of the sound signals mixed with a constant sound signal is selected, the sound signal mixed with a constant volume signal through the tape is selected, and the mixed sound signal recorded on the tape is reproduced by the tape record (C). The amplified signal is inputted to the sound signal control unit (C) through the sound signal selection unit (b), adjusted to a signal of a desired size, and then the adjusted sound signal is input to the frequency separation unit (d).

In addition, when the external voice signal is selected by the operation of the volume signal selection unit (b), the external voice signal is adjusted to a voice signal of a predetermined size by the variable resistors VR1 and VR2 of the level adjusting unit A. The acoustic signal adjusted by the level adjusting unit A is amplified by the field effect transistor FET and the transistor TR1 of the acoustic signal amplifying unit B, and the peripheral elements thereof, so as to adjust the acoustic signal selection unit B and the acoustic control unit. Through (c) it is input to the frequency separation unit (d).

Therefore, the frequency separation unit (D) has a low pass filter (LPF1-LPF3) for passing only a predetermined frequency band or less for the sound signal adjusted and input from the level adjusting unit (C), and a high for passing only a predetermined frequency band or more. Passing through each of the pass filters (HPF1-HPF2) are separated into a frequency band having a predetermined number of desired ranges, where the low pass filter (LPF1) band 3KHz or less, the low pass filter (LPF2) band 5KHz or less, The low pass filter LPF3 passes only 7 KHz or less bands, while the high pass filter HPF1 passes only 100HZ or more bands and the high pass filter HPF2 passes only 200 Hz or more bands, and transmits them to the frequency selection unit e. Done.

Therefore, the frequency selection unit (A) selects necessary frequencies for a plurality of frequency band signals having a predetermined range separated through each filter of the frequency separation unit (D), and accurately selects and amplifies only specified independent frequencies. When the frequency is set to 100Hz, 300Hz, 1KHz, 3KHz, 10KHz, 100HZ is input from the band signal input from the first equalizer EQ1, 300Hz from the second equalizer EQ2, 1KHz from the third equalizer EQ3, and the fourth aquilai. In the low EQ4, only 3 KHz and the fifth aquilizer EQ5 accurately select and equalize and amplify only 10 KHz, and then output the signal to the signal amplifier.

On the other hand, the signal amplifying part (f) in the frequency selection unit (e) The first to the fifth equalizer (EQ1-EQ5), each amplifier with respect to a specified stand-frequency output from each circuit (Amp _A -Amp _A) of the operation The amplifier OP1-OP5, a capacitor, which is a peripheral circuit element, and a resistor are amplified, and the amplified signal is output to the phase controller.

Accordingly, the phase control unit 4 drives transistors TR2-TR6 of the respective phase control circuits P _A- A _E with signals input from the signal amplifying unit _F , and the transistors TR2-TR6. According to the driving of the differential junction transistors UJT1-UJT5, the thyristors SCR1-SCR5 are turned on to control the phase angle, thereby outputting a phase-controlled pulse signal from the pulse transformers PT1-PT5.

Therefore, the drive circuit (H) controls the conduction angle of the thyristors (SCR6-SCR15), which are the lamp driving units (LD _A -LD _E ), by the pulse signal output from the phase control unit (G). Accordingly, it is possible to variably control the lighting and brightness of the multi-colored color illumination lamp (AE).

As described in detail the light process of the multi-color color light (AE), the signal input whether the sound signal of the tape or the external signal through the microphone (MIC) through the sound signal selection unit (b) is a signal controller ( By adjusting the sound signal of a certain width by the input to the frequency separation unit (D), the external input through the microphone (MIC) is a complex input of the audio signal within the audible frequency, the sound signal of the tape is a frequency The sequence recorded by the signal tape made by combining the randomly selected frequencies (100Hz) (300Hz) (1KHz) (3KHz) (10KHzMIC) by the first to fifth equalizers (EQ1-EQ5) respectively. Depending on the type or are sequentially input to the frequency separation unit (d).

Since the frequency divider D is composed of a high pass and a low pass filter, the low pass filter LPF 1 (LPF 2) at a frequency of 3 KHz, 5 KHz, 7 KHz or more through the low pass filters LPF 1, LPF 2, and LPF 3. The LPF3) blocks frequencies above 3KHz, 5KHz, and 7KHz, respectively, and the high pass filter (HPF1) (HPF2) receives audio signals while the frequencies below 100Hz and 20Hz are cut off, respectively. It is a band pass filter for attenuating the frequency and passing the necessary sound signal to the frequency selection unit (e).

Therefore, the sound signal input to the frequency separation unit (D), which is the bandpass filter, is separated and input for each designated frequency of the frequency separation unit (E). The low pass filter LPF1 is applied by the frequency separation unit (D), the bandpass filter. The sound signals passing through the LPF2, LPF3 and the high pass filter HPF1 and HPF2 are each of the first to fifth equalizers EQ1-EQ5 corresponding to the specified frequencies of the frequency selection unit (e). (300Hz) (1KHz) (2KHz) (10KHz) are each independently accurately selected and amplified.

For example, if the tape recorder (C) is designated by the signal selector (B) to drive the tape, the frequency signal of 10Hz, 300Hz, 1KHz is generated from the frequency separation unit (D) among the fornication signals recorded on the tape. For example, assuming that the signals are sequentially input at predetermined time intervals of about 1 second, the signal passes through the low pass filter LPF1, LPF2, LPF3 of the frequency separator D. The first to third equalizers EQ1, EQ2, and EQ3 of DP pass through the first equalizer EQ1 designated as the frequency band of 10 Hz for 1 second, and the second equalizer EQ2, which is the next 300 Hz frequency band, for 1 second. The signal of the third equalizer EQ3, which is in the frequency band of 1Kz, passes through the next one second.

In addition, when 3KHz and 10KHz signal frequencies are combined and supplied, a 4K equalizer (EQ4) of 3KHz and 10KHz, which are corresponding frequency bands of the frequency selection unit (H), are passed through a high pass filter (HPF1) (HPF2). The signal is supplied to the 5 equalizer EQ5 in a complex manner, and the remaining first to third equalizers EQ1, EQ2, and EQ3 do not have a corresponding frequency and thus there is no selection and amplification.

On the other hand, the sound signals respectively passed through the frequency selection unit (e) is amplified in the signal amplifier (bar), in the case of the former one-second interval signal of 100Hz, 3000Hz, 1KHz each of the first to third equalizer (EQ1) ) (EQ2) (EQ3) through the signal amplifier circuit _{(amp a) (amp B)} ( and are input in turn in one-second intervals in the operational amplifier (OP1) (OP2) (OP3 ) amplification of amp _C), the latter The composite signal of 3KHz and 10KHz passes through the fourth and fifth equalizers EQ4 and EQ5 of the frequency selection unit _E , and the operational amplifiers OP4 and OP5 of the signal amplifier circuits Amp _D and Amp _E. The composite input is amplified.

The signal amplified in this way is sequentially phased by the phase control unit 1 second to each phase control circuit P _A (P _B ) (P _C ), so that the transistors TR2 (TR3) (TR4) and uni When the junction transistor (UJT1) (UJT2) (UJT3) and the thyristor (SCR1) (SCR2) (SCR3) are controlled and controlled, the pulse output (PT1) (PT2) (PT3) is controlled to drive the pulse output. 3KHz and 10KHz, which are complex signals, correspond to the phase control circuits P _D (P _E ), so that the transistors TR5, TR6, Unijunction Transistor UJT4, UJT5, and Dyristor SCR4 The control drive (SCR5) is performed and the pulse transformers PT4 and PT5 are controlled to output the pulse output to the drive circuit H.

The electronic one-second interval sequential signal is applied to the thyristors SCR6, 7 (SCR8, 9) (SCR10, 11) of the lighting circuit driving circuit LD _A (LD _B ) (LD _C ), which are the drive circuit (a). Since each phase is driven to control the phase angle, the currents of the lamps A, B, and C are controlled to control the current of the lamps A, B, and C. ) Can be sequentially turned on at 1-second intervals, and the latter composite signal is used to drive the thyristors (SCR12, 13) (SCR14, 15) of the lamp driving circuit LD _D (LD _E ) of the drive circuit (H). Since each phase is driven to control the phase angle, the current of the lamps (D) (E) is controlled to simultaneously illuminate the lamps (D) (E) designated for each color (D color) (E color) to produce multicolored lights. It will be possible.

At this time, if the sound signal is mixed with strong, weak, etc. through the tape (TAPE) or microphone (MIC) of the signal input unit (A) in the process of lighting the corresponding color light (AE), strong, weak, fast Acoustic signal having a through the frequency separation unit (D), frequency selection unit (E), the signal amplifier (bar) while the phase control unit (G) controls the phase of the sound signal of the strong, weak, and fast The brightness and lighting time of the color lighting lamp AE of the drive circuit A are varied according to the change in the conduction angle of the direciter SCR6 and SCR15 of the drive circuit H. As the brightness and lighting time of AE) are varied, the lights of various colors can be harmonized with each other to produce a gorgeous harmony of lights.

As described above, the present invention is divided into a plurality of predetermined frequency bands in order to distinguish the sound by the number of the multi-color light to turn on the sound signal generated from the sound device or the microphone, and the separated sound signal is divided into a plurality of equalizers. By re-extracting only the predetermined predetermined frequency band, the relevant lighting is turned on as well as its separated frequency is passed through the phase control circuit to change the conduction angle of the lighting power according to the frequency level of the sound signal. By varying the brightness and lighting time of the lamp automatically, the multi-colored lights can be combined with each other by the natural frequency and volume level of the timbre to produce colorful and diverse lighting.
