RGB and RGBW LED Tapes

LED ribbons with conventional white LEDs, as well as with dynamic light (red, yellow, blue and green) are common everywhere. Their hybrid – four-color or RGBW bands give out, except the main three colors, in addition and white.

What it is?

LED Assembling RGB Coloring – Supplement for Lights, Glowing Exceptionally White Light. In the simplest case, when the RGBW bands were not found at hand, there are color-colored – either by white links (for each color) or everything immediately, alternating with each other White, Red, Green and Blue Glow.

Progress is not standing on the spot – built-up armed LEDs, producing white, red, green and blue colors. In such a composite LED, 4 simple blueprints are built, each of which gives its color. The control provides either a 5-pin (5-wire) line, or a two-wire, on which power is supplied to the LED, having a primitive microcontroller. In the latter case, 5 crystals are placed in “MultiSeVodiod”: 4 light-emitting, one (simple chip) managing. As a chip, a multivibrator (dimmer) is provided, consistently feeding powered by itself, which comes on an external two-wire line, onto the corresponding blueryryryryrs.

Analog RGBW – five-component (5-critical) LED, which also contains yellow. RGBW assembly would be RGBWY LED. Such a modification of multi-element LEDs did not find use in practice – yellow color is reproduced by simultaneous glow of red and green bevel. Close-to-friendly aircraft sites, when the observer is located in one or two meters (and further) from them, merge into its field of view in a single lightness. This feature of vision, open yet Lomonosov and confirmed in practice by Helmholtz, allows you to create an arbitrary shade from the visible to the eye of 16777216 variations. Changing, for example, the brightness of a red and green glow, a man sees a reddish-yellow-colored tint on the RG LED.

RGBW-ribbons have an interesting feature – light-mement. If the White Filmrystal will suddenly refuse, then with the help of red, blue and green, which are still working, you can recreate a dynamic white light – from a cold to warm, exhibiting the appropriate brightness. The ratio of the brightness of these three LEDs for simple white (without squeezing on the color temperature scale) Next: 30% of the light gives red, 59% – green, 11% – blue.

If you slide a little glow of green and add blue – the shade will be cold white. If the blue is reduced, and add red – the tint will be warm white. Etc. In industrial lights, this process is not managing a person, but a special device is a dimmer microcontroller, which sets shades and frequency, algorithm for their time changes.

The built-in microcontroller with rigidly specified glow modes is located in each of the LEDs: when you turn on such links, all four light elements are glowing simultaneously. Smooth or sharp cyclic switching is set using an external dimmer. Address (algorithmic) – using an additional digital (three-wire line).

In the latter case, such systems are noticeably more expensive than the simple RGBW tape.

Summarize. W – White LEDs are the main. These are light elements that give light for everyday life of people at home and at work. Crystals R, G and B – Red, Green and Blue give background backlight. So, in LED chandeliers, managed from the console, the backlight of the owner chooses independently. For example, for the new year, users often include RGBW-tape or lamp in the “Running lights” mode, as on the Christmas Garland: Red, Green and Blue blink sequentially or with different periodicity.

The ceiling is highlighted in such a way, a festive view. Users who prefer sharp flashing, flickering smooth transition from one color to another, choose another mode. The use of arbitrarily programmable microcontrollers ARDUINO allowed each owner such links to set their algorithm, not limited to one or more factory presets.

RGBW flexible tapes – at 5, 12 and 24 volts, in contrast to 220-volt, cut into sectors shorter than 0.5 or 1 meter. The ceiling, walls and gears with stepped transitions are placed around the perimeter using short and long segments connected by 90-degree connectors that create tape turns to this angle. So, the room with dynamopodesight acquires an elegant and finished appearance. The simplest links without dimmer switch are connected directly. They will need a power supply (adapter, driver) with two independent output voltages: 2 volts – for colored LEDs, 3 – for white.

Necessary accessories and components

In addition to multicolor diode tape, the master will require accessories and components.

  • Corner connectors.Most often these are rectangular connectors – by one turn. Tees – T-shaped connector connectors. “Crossings” serve to connect intersecting multi-wire tires, “pluses” and consoles are electrically isolated from each other. Stars – in special cases: 5, 6, 7- and more finite allow one of the tapes to ensure a connection with the power supply, and the center “Stars” – the multi-mector into several bands will share the supply voltages with the rest of the ribbons. Connectors- “Crossings” and “Stars” are disseminated weakly, due to their uniqueness – a user who knows how to solder, collects such a topology with the segments of the wire.

  • Power cable – when tapes a lot, a decent section is required. 12 volt tape with power, for example, 10 watts on the trafficphone meter, consumes almost amp. Consequently, 5 m Slims consumers: 5/6 and multiplied by 5 m, will give 25/6, or more than 4 A. And considering the heat loss (on the LEDs and the wires under the load), it will only reach the tape only 2.5 A. In order for the obtained light assembly to disappointed you with a small one, which is declared by the manufacturer, the luminosity, you need a cable with a margin that allows you to bring 10 A without a noticeable supply voltage drop under load. Many homemade workers, encountered with this need, take a common segment of the cable to which several links are connected, with a cross section of 2-5 mm2 – and do not lose: if the power supply is quite powerful, then the links are glowing with the declared brightness.

  • Universal glue. Liquid nails can be used, resembling Glue “Moment-1”.

  • White box with a transparent lid (can with diffuser) or a transparent silicone tube. In the latter case, a garden or technical hose is suitable, transmitting white light – with an inner diameter somewhere in a centimeter with a little. Packaging Ribbon will give the assembly of water and dustproof. Ready-made lights with a class of waterproofing IP-69 are already placed in a dusty-inferred shell. Sealed simolet, although losing a little – up to 10% luminosity in the shell, is extremely protected from external weather and microclimatic (mechanical and chemical) effects.

  • Power Supply. Can be supplied included. If the RGBW tape without a controller is operating from 220 V, t. E. “From the outlet”, then a network rectifier is mounted as a device in a mini capsule on a network cord. This is a high-voltage diode rectifier. In parallel, he – the output is connected to a high-voltage capacitor, as a rule, with a margin from voltage drops up to 400 V.

  • Diverse fastening: dowels and screws for them. Need to suspend power supply.

Tools – Knife for stripping wires and contacts, soldering iron with solder, rosin and solder flux, screwdriver. Skaika is needed in non-standard cases when there are no connectors with the desired topology, and it is necessary to suspend the light elements.

Some terminals have screwed clamps.


The conclusive functional node – the mini-card in the housing with the outputs is connected to the power supply to the corresponding entry on it. As a rule, these are conclusions “+ 5V” (or 12 V) and “Earth” (“Mass”). The controller outputs are also loaded: the supply of the microcircuit is controlled through power transistor cascades working as keys. As a rule, it is “minuses” on “R”, “G”, “B” and “W”, and the “plus” they have a common, but there are back polarity – with the general “mass”. 5-wire power line is formed.

The complicated scheme is as follows: “Plus” and “minus” here are the only. The LED (Flood Streams) is suitable for general food. Chip in the LED case yourself – local switches the colors of the glow. Then “minus” “sits” to the general wire, “plus” is separate, and in the control bus, there is a high-speed line on the digital protocol – wires on the “reception” and “transmission”.

Controller, finding that the movements are connected and ready to work, sends them address commands over the bus (“RX” / “TX” / “Mass”). Suddenly connect the “plus” to “reception” or “transmission” – a common mistake of beginner masters: chips and a head controller (“brain”), non-protection, instantly burned (thermal and electric sample of the microprocessor part).

The fact is that the high-frequency pulse voltage with which they work is the hundredths and thousands of voltages – somewhat and more volt instantly “kill” electronics.


The amplifier of digital signals from the complex (“intellectual”) RGBW-link control system is required when the length of the software line is hundreds and more than meters. To compensate for the losses of the RF voltage, which is so scrub, and the amperezh it is a micronomer unit, in the long cable is provided. N. booster. Find and choose it problematically – the product is only a few firms, t. To. Similar situations are very rare. Enthusiasts collect such schemes independently, acquiring radio elements in China online.

As for the power amplifier – when the simolent in the last sections “Sailing” in brightness, sometimes cheaper to purchase an additional adapter by 5, 12 or 24 volts than to invest several times a large amount per stranded cables with thick cross section. The disadvantage of such a solution is a power supply, in favor of the integrity of the initial design of the room, hide under the suspended chandelier design, for it – from the side opposing from the entrance to the room. Food is powered by additional wires through the converted connections to which small conclusions for wires are connected.

Power Supply

Any adapter is suitable for an adapter with 220 to 12/24 volt module, providing a signment from high network voltage. Alternating voltage It turns into constant – due to it, the links do not flicker, tiring the user’s eyes at many hours, and give smooth, without ripples the main light and the background lighting.

Tips for choosing

Avoid the use of links, which flickers when working. Pulsation – with a frequency of 50-100 Hertz also give the simplest power supplies (transformer and two diodes, even without a smoothing capacitor). Choose and coordinate the power of the power supply and the total consumption (by watts) the Swords themselves. If the first is less than the second – the glow is incomplete, and the unit operates in overload mode, either periodically turns off over overheating.

If on the contrary – all the assembly will last for many years without complaints, t. To. The power supply has a power supply.

Connection and configuration

For mounting and setting up dynamic RGBW-lighting, make the following.

  1. Install the power supply. Place it in a hidden place – a niche in the wall, behind the cabinet and t. D.
  2. Slims in the right places.
  3. Connect connectors. If the segments of the link are connected using soldering, in advance – to the location of the tape, smear the segments for hard-to-reach places for the ceiling, floor and walls.
  4. Mount and plug the output and network cables (cords) to the power supply.
  5. Hang and connect the controller (if any), compliance with the instructions for assembling and commissioning the device.
  6. Fit and connect the wires (and their segments) by referring to your individual planning of the lightsystems.

Check if the system is collected correctly. All the light assembly should light up. If the console is provided – insert batteries or batteries in it and check the mode switching in the glow. Burn the glow modes – all set by the factory must work. If programming is provided from the console – install your color and white light switching algorithm. The result is a multi-colored glow, which comes in a combination with the main (white) or without it.
