Five-channel LED color music. How to make color music using LEDs How to connect light music

Adviсe

It's hard to find a person who doesn't like listening to music. To satisfy this desire, high-quality music centers, speakers and other devices are purchased. To get even more pleasure, many people think about creating special color effects that can decorate any sound and create a romantic atmosphere on a date or a fun mood when organizing a holiday party. Color music, like music centers, can be purchased, or you can make it yourself. The best option is to make color music using LEDs according to one of the proposed schemes.

Advantages of LED products

The modern electronics market presents a wide variety of LED strips that have a wide variety of color effects. With their help, you can create high-quality spot lighting; it is possible to create color music with flashing or blurry effects.

Unlike conventional light bulbs, LEDs have many positive characteristics. Among the main advantages of LED strips are:

wide and varied range of colors;
rendering rich colors;
different design options - rulers, modules, discrete elements, RGB strips;
high response speed;
minimum amount of energy consumed.

The ribbons can be used at home, in clubs and cafes, and can be used to effectively illuminate shop windows. This article will describe in more detail the option of LED color music for ordinary home use.

Simple circuit with one lamp

To begin with, it’s worth studying a simple color music scheme. This is a device that consists of one LED, transistor and resistor. Power for such color music can be supplied from a constant current source with a voltage of 6-12 volts. The device operates on the principle of an amplification stage with a common emitter. The impact in the form of a signal varying in frequency and amplitude arrives at the main base. As soon as the oscillation frequency exceeds a certain threshold value, the transistor opens and the LED immediately flashes.

This scheme has one drawback - the LED blinking rate depends entirely on the level of the sound signal produced. In other words, the light effect will be activated only at a certain level of volume produced by the music center. When the sound intensity decreases, the glow will be constant with occasional winks.

Scheme with one-color ribbon

This color music on a transistor is assembled using an LED strip in the load. To organize such color music, you will need to increase the power supply to 12 V, find and install a transistor with a maximum collector current that exceeds the load current, and you will also need to recalculate the total value of the resistor. This color music is quite simple, made on one single-color LED strip and is ideal for beginner radio amateurs. You can assemble it without any problems at home.

Simple three-channel circuit

To get color music that is free of all the disadvantages listed above, you should use a special three-channel sound converter. Such a circuit is powered by a constant voltage of 9 V and is able to effectively illuminate one or two LEDs in each channel. Among the main structural elements that characterize such a color-musical scheme are:

three independent amplifier stages, which are assembled using transistors of the KT315 (KT3102) category;
LEDs of different colors are included in the transistor load;
For the pre-amplification element, a network small step-down transformer can be used.

The incoming signal is fed to the secondary winding of the transformer, which in turn performs two main functions - it decouples two devices at the galvanic level, and also amplifies the sound from the main linear output. After this, the signal is sent to three parallel and connected filters, assembled on the basis of RC circuits. They operate on an individual frequency band, which directly depends on the value of the capacitor and resistor.

Color music with RGB tape

This attachment circuit operates on 12 volts and is ideal for installation on a car. This color music optimally combines the main functions of the previously discussed schemes and is able to work both in the lamp mode and in the color music mode. The second mode is achieved through special non-contact control of the RGB strip via a microphone. As for the lamp mode, it is based on the simultaneous launch of the green, red and blue LED at full power. The mode can be selected using a special switch located on a special board.

To understand how this attachment works, it is worth studying its sequence of actions. The main source of the signal here is a microphone, which converts sound vibrations emanating from the phonogram. The received signal is insignificant and therefore requires amplification. This can be achieved by using a transistor or a special operational amplifier. After this, the automatic AGC level controller starts. It effectively keeps sound fluctuations within reasonable limits and prepares it for subsequent processing. Built-in filters divide the signal into three parts, each of which operates in one specific frequency range. Finally, you just need to amplify the previously prepared current signal. For this purpose, special transistors are used that operate in key mode.

Purchase of a ready-made CMU

If you don’t want to make a color music system for use at home, you can purchase a CMU, that is, a color music installation. This is a ready-made functional solution that includes a controller. It will process the sound, converting it into a light and music visual representation. In the process of reproducing the light, its intensity and color scheme will change, thereby creating the effect of a real disco. The CMU device also includes a panel with built-in diodes.

These devices may be based on a spectral decomposition into frequencies, where each of them will have a specific color scheme or preset adjustments with a variety of effects and their alternation. They can be configured using the included remote control.

Important! Modern CMUs are very simple to install and configure. This is an ideal solution for organizing a home party or disco.

Conclusion

There are quite a lot of schemes for independently performing color music settings. You can choose a fairly simple option, where the color of the RGB tape will simply change, to quite complex ones, which in the process of work will create a large number of different effects, overflows and attenuations. Depending on your skills, you can choose and execute the appropriate option. It is enough to work a little and create something truly unique; it will be lighting equipment that delights with the shimmer of a wide variety of color shades. Also, do not forget that there is always the opportunity to buy a ready-made color music solution and fill your home with color shades and joy.

Almost all color music devices of sufficient power are designed for the use of conventional incandescent lamps. There are also CMU circuits on LEDs on the Internet, but they are usually for low-power LEDs. How to connect 50-100 watt LEDs to such a device? You can take as a basis one very good color music scheme (also with sound control via a microphone) and slightly modify the output part - get the desired result.

CMU circuit for high-power LEDs

Schematic diagram of the CMU for 220V

Schematic diagram of the CMU for 12V

The electrical power supply for the input part of the frequency processing is made on a piece of a universal board. The transformer was taken from some kind of radio. It is ideal because it is symmetrical and has 10V windings. BT151/600 thyristors were used as powerful switches, with a margin so that they would not burn out from high currents.

The circuit can be made completely isolated from the network if the executive part is used using triacs and optocouplers.

When testing, temporarily install resistors of rated resistance and power from 10 W instead of LEDs.

CMU with 12 V LED strips

If you want to use 12 V DC LED strips in the CMU, then you can power the entire circuit with the same 12 volts from a pulse network driver, and assemble the output part using high-power field-effect transistors.

A version of the diagram is shown above. Here resistor R2 sets the current limiting of the LED strip (or a powerful single LED).

By the way, when installing individual high-power LEDs, for example 100 watts (32 V at 3 A), supply the supply voltage from the driver through the LED to the drain of the field-effect transistor (after making sure from the datasheet that it can withstand such U/I parameters), and the specified Use the resistor above to set the desired current level.

The body is made of wood (easier to find the material and easier to process). The holes for the lamps are drilled with large cutters. Naturally, on the front there are all the necessary knobs for adjusting signal levels and HF-MF-LF channels and a power button.

Do-it-yourself color music - what could be more pleasant and interesting for a radio amateur, because it is not difficult to assemble if you have a good circuit.

In modern radio engineering there is a huge variety of radio elements and LEDs, the advantages of which are difficult to doubt. A wide range of colors, bright and rich light, high speed of response of various elements, low energy consumption. This list of advantages can be continued endlessly.

The principle of operation of color music: LEDs assembled according to the circuit blink from an existing sound source (this can be a player or a radio and speakers) at a certain frequency.

Advantages of using LEDs over those previously used in CMU:

luminous saturation of light and a wide color range;
good speed;
low energy consumption.

The simplest schemes

A simple color music that can be assembled has one LED and is powered by a 6–12 V DC source.

You can assemble the above circuit using an LED strip and selecting the necessary transistor. The disadvantage is that there is a dependence of the LED blinking frequency on the sound level. In other words, the full effect can be observed only at one sound level. If you lower the volume, there will be a rare blinking, and if you increase the volume, a constant glow will remain.

This drawback can be eliminated using a three-channel sound converter. Below is a simple circuit; it is not difficult to assemble it with your own hands using transistors.

Color music circuit with three-channel sound converter

This circuit requires a 9-volt power supply, which will allow the LEDs in the channels to light. To assemble three amplification stages, you will need KT315 transistors (analogous to KT3102). Multi-colored LEDs are used as a load. A step-down transformer is used for amplification. Resistors perform the function of adjusting LED flashes. The circuit contains filters for passing frequencies.

The scheme can be improved. To do this, you need to add brightness with 12 V incandescent light bulbs. You will need control thyristors. The entire device must be powered from a transformer. You can already work according to this simplest scheme. Color music using thyristors can be assembled even by a novice radio technician.

How to make color music using LEDs with your own hands? The first thing you need to do is select an electrical circuit.

Below is a diagram of a light and music system with an RGB strip. For such an installation, a 12 volt power supply is required. It can work in two modes: as a lamp and as a color music. The mode is selected by a switch installed on the board.

Manufacturing stages

It is necessary to make a printed circuit board. To do this, you need to take foil fiberglass with dimensions of 50 x 90 mm and a thickness of 0.5 mm. The board manufacturing process consists of several stages:

preparation of foil PCB;
drilling holes for parts;
drawing paths;
etching.

The board is ready, components have been purchased. Now begins the most crucial moment - the wiring of radio elements. The final result will depend on how carefully they are installed and sealed.

We assemble our printed circuit board with the components soldered on it into such an accessible lampshade.

Brief description of radioelements

Radioelements for an electrical circuit are quite affordable; purchasing them at your nearest electrical goods store will not be difficult.

For color and musical accompaniment, wirewound resistors with a power of 0.25–0.125 W are suitable. The amount of resistance can always be determined by the colored stripes on the body, knowing the order in which they are applied. Trimmer resistors can be both domestic and imported.

Capacitors produced by industry are divided into oxide and electrolytic. It won’t be difficult to select the ones you need by doing basic calculations. Some oxide capacitors may have a polarity that must be observed during installation.

You can take a ready-made diode bridge, but if you don’t have it, then a rectifier bridge can be easily assembled using diodes of the KD or 1N4007 series. LEDs are taken as usual, with a multi-colored glow. The use of LED RGB strips is a promising direction in radio electronics.

LED RGB strip

Possibility of assembling a color and music console for a car

If you manage to please with color music from an LED strip made by yourself, then a similar installation with a built-in radio can be made for a car. It is easy to assemble and quick to set up. It is proposed to place the set-top box in a plastic case, which can be purchased in the electrical and radio engineering department. The installation is reliably protected from moisture and dust. It is easy to install behind the dashboard of your car.

You can also make a similar case yourself using plexiglass.

The plates of the required dimensions are selected, two holes are made in the first part (for power supply), and all parts are sanded. We assemble everything using a heat gun.

An excellent lighting effect is achieved if you use multi-colored (RGB) tape.

Conclusion

The well-known saying “it is not the gods who burn the pots” remains relevant today. A diverse range of electronic components gives craftsmen wide scope for imagination. DIY color music on LEDs is one of the manifestations of limitless creativity.

simple scheme of color music using 220V lamps

Everyone knows and almost everyone assembles this device that flickers and blinks to the music - color music. On the Internet, many search for color music schemes using various queries and they are different everywhere. I present to your attention the diagram below, the appearance of which you see in the pictures. And so, circuit of working color music for 220 Volts on teristors

A simple color scheme

It will require the bare minimum of parts.

We buy colored incandescent lamps 220V
Considering that the output stage of the color music is made of thyristors, it has a lot of power. If thyristors are placed on heat sinks, then each channel can be loaded with 1000 watts. But for a home, 60-100 watt lamps are quite enough.
