How RGB lights Work And How To Control Color

How RGB lights Work And How To Control Color

An RGB led lights is a combination of three LEDs in just one package: red, green and blue; there are two kinds of RGB LEDs: common cathode and common anode RGB LEDs; you generate different colors by adjusting the brightness of each of the three LEDs of the RGB LED; to adjust the brightness of each LED, you use a PWM signal.RGB lamps are imaged by three primary colors. 

In addition, there are blue LED with yellow phosphor, and ultraviolet LED with RGB phosphor. On the whole, both have their own imaging principles. The color of some LED backlight panels is particularly clear and bright, even to the extent of high image quality television. This situation is the characteristic of RGB, which boasts that red is red, green is green, and blue is blue. In terms of light color mixing, it has more diversified characteristics.

 

How RGB lights Work?

Three chips of red, green and blue are placed in one lamp bead, or a PCB or IC is placed in the ordinary two foot lamp bead to control the flashing sequence and frequency.Or the lamp beads with four legs, one of which is the cathode or anode shared by the three chips, and the other three legs are connected to a chip one by one to control the light through the current conduction of the three legs.

Such a lamp can emit seven colors: red, green, blue, red green, red blue, green blue, red green blue (that is, white light), or if the four leg lamp is willing, it can also control the current flowing through different color chips to control the brightness of a color, thus causing the color change of the mixed light. In theory, a lamp can emit an infinite number of colors.

RGB

Working principle of rgb lamp bead: when two LEDs are lit by three primary color LEDs respectively, it can emit yellow, purple and cyan (for example, when red and blue LEDs are lit, they emit purple light); If red, green and blue LEDs are lit at the same time, it will produce white light.If there is a circuit that can make the red, green and blue LEDs light up in two, separately and simultaneously, the three primary color LEDs light up, then it can emit seven different colors of light, so this phenomenon occurs.The color changing lamp is composed of red (R), green (G) and blue (B) LEDs. Two color LED is very familiar to us. It is generally composed of red LED and green LED.

Luminescence mechanism:The terminal voltage of the PN junction constitutes a potential barrier. When the forward bias voltage is applied, the potential barrier drops, and most carriers in the P and N regions diffuse to each other. Since the electron mobility is much higher than the hole mobility, a large number of electrons will diffuse to the P region, forming the injection of a few carriers in the P region. 

These electrons recombine with holes in the valence band, and the energy obtained during recombination is released in the form of light energy. This is the principle of PN junction luminescence.

Luminous efficiency:It is generally called the external quantum efficiency of the component, which is the product of the internal quantum efficiency of the component and the removal efficiency of the component. The so-called internal quantum efficiency of the module is actually the electro-optical conversion efficiency of the module itself, which is mainly related to the characteristics of the module itself (such as the energy band, defects, impurities of the module material), the barrier crystal composition and structure of the module, etc. 

The removal efficiency of the module refers to the number of photons generated inside the module that can be actually measured outside the module after being absorbed, refracted and reflected by the module itself. Therefore, the factors concerning the removal efficiency include the absorption of the component material itself, the geometric structure of the component, the refractive index difference of the component and packaging material, and the scattering characteristics of the component structure. 

The product of the internal quantum efficiency of the component and the removal efficiency of the component is the luminous effect of the whole component, that is, the external quantum efficiency of the component. Early module development focused on improving its internal quantum efficiency. 

The main method is to improve the quality of the barrier crystal and change the structure of the barrier crystal, so that electrical energy is not easily converted into heat energy, and then indirectly improve the luminous efficiency of LED, so that about 70% of the theoretical internal quantum efficiency can be obtained, but such internal quantum efficiency is almost close to the theoretical limit. 

In this case, it is impossible to improve the total light quantity of the module by improving the internal quantum efficiency of the module, so improving the removal efficiency of the module has become an important research topic. The main methods are: change of grain shape – TIP structure, surface roughening technology.

 

How RGB lights To Control Color?

An RGB lighting is a combination of 3 LEDs in just one package:Red,Green and Blue.You can produce almost any color by combining those three colors. With an RGB lighting you can, of course, produce red, green, and blue light, and by configuring the intensity of each LED, you can produce other colors as well.

For example, to produce purely blue light, you’d set the blue LED to the highest intensity and the green and red LEDs to the lowest intensity. For a white light, you’d set all three LEDs to the highest intensity.To produce other colors, you can combine the three colors in different intensities. 

RGB

To adjust the intensity of each LED you can use a PWM signal.Because the LEDs are very close to each other, our eyes see the result of the combination of colors, rather than the three colors individually.When the red, green and blue lights overlap with each other, the colors are mixed, but the brightness is equal to the sum of the two brightness. 

The more mixed the brightness is, the higher the brightness is, that is, additive mixing. Colored light can be diluted and brightened by colorless light. If blue light and white light meet, the result is a brighter light blue light. The superposition of red, green and blue lights. The brightest superposition area of the central three colors is white. 

The characteristics of additive mixing: the brighter the superposition is, the brighter it will be. Each of the red, green and blue color channels has 255 levels of brightness. At 0, the “light” is the weakest — it is turned off, and at 255, the “light” is the brightest. When the three colors have the same value, it is a colorless gray color, while when the three colors are 255, it is the brightest white, and when they are all 0, it is black.

LED rgb lights is becoming the latest in LED trends due to their energy-saving characteristic, ability to create vibrant colors (red-green-blue), excellent brightness, and flexibility to work in different applications such as commercial, landscape, and architectural. Apart from installing them indoors, the water-resistant feature also allows you to use them in outdoor settings.

The most commons are outdoor Christmas light decoration and Halloween lights.LED rgb lights program colors to match your moods and for specific situations.With the advancement in technology, they come with several features like programmable options, remote control, smartphone app navigation features, and timer for the convenience of users to handle wirelessly at a distance and perform hassle-free functioning.Every Christmas, everyone uses RGB lights as outdoor Christmas light decoration or as Halloween lights.

What Do You Wanna To Know About RGB LED Lights

1;What is RGB in LED lights?

RGB LED means red, blue and green LEDs. RGB LED products combine these three colors to produce over 16 million hues of light. Note that not all colors are possible. Some colors are “outside” the triangle formed by the RGB LEDs.

2;What are RGB lights used for?

Use RGB LEDs for effective lighting in kitchens, studies, porches/entrances, pathways and driveways, Or for decorating party lights. They are also ideal for atmospheric lighting throughout the home and also known as party lights.

3;Are RGB lights better than LED?

Although RGB can produce a colour close to white, a dedicated white LED provides a much purer white tone and allows you the option of an extra warm or cool white chip. The extra white chip also provides extra scope for colour mixing with the RGB chips to create a huge range of unique shades.

4;What is the difference between LED and RGB LED?

LED lighting works differently than RGB lighting. While RGB bulbs have two colors, usually red and blue, LEDs have only one color, usually white. In fact, that’s the entire point of LED bulbs, to simply give a brighter, whiter light.

5;Which is better RGB or ARGB?

ARGB is by far more impressive and versatile than an RGB strip but usually comes at a greater cost. However, anything an RGB strip can do, an ARGB strip can replicate in addition to all the extra capabilities of individual LED control.

6;Can you leave led RGB lights on all night?

To put it simply, well-manufactured led RGB lights are extremely long-lasting and can be left on 24 hours, 7 days a week. This is because, unlike conventional types of light, led RGB lights produce minimal amounts of heat, which means they are unlikely to overheat or set on fire.

7;Is RGB better than white light?

LED lamps with diodes emitting pure white light only have the great advantage of a significantly higher light output compared to lamps with RGB modules. This means, first of all, that these lamps have a higher brightness, which is expressed in a correspondingly higher number of lumens.

8;Does RGB light waste electricity?

The actual power draw for an RGB LED strip is minimal. We’re talking less than 3W here — EKWB published a post that details exactly how much power its RGB products draw. To put that into perspective, your CPU and GPU can draw 150W and 200W, respectively.

9;Are RGB lights good for your eyes?

It can damage the retina and strain the eyes. It can also disrupt the body’s natural circadian rhythm the same way blue light from mobile phones wakes the brain when the body needs to sleep. Additionally, these seemingly short-term effects can aggravate with prolonged exposure.

10;How do you control RGB LED lights?

In a common anode RGB LED, the anode of the internal LEDs are all connected to the external anode lead. To control each color, you need to apply a LOW signal or ground to the red, green, and blue leads and connect the anode lead to the positive terminal of the power supply.

11;What colors can RGB LED make?

How does color mixing apply to LEDS and Lighting? An RGB LED is an LED module that can produce almost any color using these three primary additive colors: Red, Green and Blue. The simplest version of an RGB LED has a combination of 3 separate light-emitting diodes in one package, housed under a clear protective lens.

12;Why do they call it RGB?

The RGB color model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

13;Do RGB lights attract bugs?

What color LED lights do not attract bugs? Bugs can see Ultraviolet (UV), blue and green. That is why they are attracted to white or bluish lights such as mercury vapor, white incandescent, and white fluorescent. On the other hand, yellowish, pinkish, or orange are the least attractive to the bugs.

14;Why are people obsessed with RGB lights?

RGB lighting is popular among gamers because it can create an immersive gaming experience. By customizing the colors on their devices, gamers can create a personalized gaming environment that enhances their gameplay. Additionally, RGB lighting can also make gaming devices look cooler and more stylish.

15;Is RGB harmful?

The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration. Studies also reveal that light emitted by LEDs can cause retinal changes, if there is high exposure for even a short period of time.

16;Which RGB color is good for eyes?

Green, the mixture of blue and yellow, can be seen everywhere and in countless shades. In fact, the human eye sees green better than any color in the spectrum.

17;Can I use RGB LED Strip without controller?

These controllers control the Red, Green and Blue channels to mix colors and create the color changing effects of the strip. Without this unit, your RGB LED strips will not operate correctly so always remember to purchase one if you are using the Multicolor LED strips.

18;How do I connect RGB LED Lights to power supply?

For this, all you need to do is connect the led strips to the ends of your led splitter and then plug in your female connector to the male connector on your power supply. This will ensure that power is distributed evenly and the lights are working as they should.

19;What voltage do RGB lights use?

Typically they run around 2.2 volts, but can be higher. By checking the current level in the LEDs data sheet, the value of the required dropping resistor can be calculated so that it drops down the voltage by the required amount from the digital logic output level (5 or 3.3V).

20;How does RGB LED strip work?

RGB Strip Lights are color changing strips of light that have the ability to produce any shade of any color, and it is created by mixing up the three primary colors; Red, Blue, and Green. Their output depends on their type of controller used. They also have the ability to produce pure white light.

21;What are the different types of RGB?

RGB stands for Red, Green and Blue. These are the three primary colours of the additive colour system.

21;Can RGB LED produce white light?

Beside the red, green, and blue LED chips, there is a white LED chip in RGBW LEDs. Although, RGB LEDs create a color close to white, it cannot create a pure white tone. An extra white LED chip allows to obtain more real and more bright white light.

23;How are RGB LEDs wired?

In a common cathode RGB LED, the cathode of the internal LEDs are all connected to the external cathode lead. To control each color, you need to apply a HIGH signal or VCC to the red, green, and blue leads and connect the anode lead to the negative terminal of the power supply.

 

24;Do RGB strips use a lot of electricity?

LED strip lights do not cost a lot of electricity compared to traditional incandescent lights. Consumption is directly determined by the length of the strip light and its light density. A standard 5-meter strip will cost less than $3 a year to run, on average.

RGB color change principle explained

What’s RGB Light

RGB Lights represent red, blue and green LEDs. RGB LED products combine these three colors to produce light in over 16 million hues. Please note that not all colors are capable of being formed, and some colors are outside the triangular range that can be formed by RGB Lights. In addition, colors like brown or pink are difficult or impossible to form by RGB Lights.

The RGB color model, also known as the RGB color model or the Red, Green and Blue color model, is an additive color model in which the three primary colors of red, green and blue are added in different proportions to synthesize and produce various colors of light.

The main purpose of the RGB color model is to detect, represent and display images in electronic systems, such as TVs and computers, using the brain to force visual physiological blurring (defocusing), synthesizing the three primary color sub-phenomena into one color pixel to produce perceived color (in fact, this true color is not the synthetic color produced by the additive color method. 

Because the three primary colors of light never overlap together, only human beings in order to The reason is that the three primary colors of light never overlap, but the human brain forces the eyes out of focus in order to “want” to see the color. (The situation is actually a bit like looking at those Autostereograms stereograms. 

Where the brain and eyes are distorted to see the stereoscopic image of what they “want” to see). The red, green and blue model is also used in traditional photography. Before the electronic age, the RGB color model had solid theoretical support based on human perception of color.

RGB is a device-dependent color space: different devices detect and reproduce specific RGB values differently because color substances (fluorescents or dyes) and their individual response levels to red, green, and blue vary from manufacturer to manufacturer, and even from time to time for the same device.

RGB color change principle explained

Is through the three base color LEDs are lit when two LEDs, it can emit yellow, purple, cyan (such as red, blue two LEDs when lit purple light); if red, green, blue three LEDs lit at the same time, it will produce white light. If there is a circuit to make red, green, blue LEDs are lit two by two, lit separately and three primary color LEDs lit at the same time, he will be able to send seven different colors of light to, so there is a seven-color LED lights of this phenomenon.

Color-changing lights are composed of red (R), green (G), blue (B) three primary color LEDs. Two-color LEDs are very familiar to us. Generally composed of red LED and green LED. It can emit red light or green light alone. If the red light and green light at the same time when the bright spot, red and green light mixed into orange.

RGB lights

Color is a property of light, without light there is no color. Under the illumination of light, people feel the color of various objects through the eyes, these colors are the combined effect of the characteristics of the human eye and the objective characteristics of the object.

Color television technology is based on the visual properties of the human eye to transmit and receive color images. Under the sunlight, people can see the colorful nature scenes. The optical theory of physics shows that light is a substance in the form of electromagnetic waves.

Any electromagnetic wave that can cause visual response of human eyes is called visible light, which is an electromagnetic wave with wavelength between 380~780nm.

The human eye can not only distinguish the size of the brightness of colored light, but also the color of the light when the intensity of colored light is sufficient. For colored light can be described by three physical quantities: brightness, hue and color saturation. In the color television, the so-called transmission of color images, in essence, is the transmission of the brightness and chromaticity of the image.

Different wavelengths of monochromatic light will cause different color perceptions, but the same color perception can originate from a combination of different spectral components.

People in the color mixing experiments found that: nature appears in a variety of colors, almost all can be mixed with a certain three monochromatic light in different proportions and get. Three monochromatic light with this characteristic is called primary light, these three colors are called three primary colors.

The three primary colors used in color television are red, green and blue. The main reason is that the human eye is most sensitive to these three colors of light, and the red, green and blue mixed together can be matched with more color.

The trichromatic principle is an important principle for decomposition and mixing of color. This principle lays the foundation for color television technology, greatly simplifying the use of electrical signals to transmit the technical problems of color.

According to the three-color principle, we only need to decompose the various colors to be transmitted into red, green, blue three base colors, and then turn them into three electrical signals for transmission.

In the receiving end, with these three kinds of electric signal can send red, green, blue color tube, can re-display the original color image. Now we use the color TV, look close to the screen, you will find that the color image is composed of many red, green and blue three dots. 

This is the use of the human eye spatial details of poor discrimination, the three primary colors of light are projected on the same surface of the red, green and blue phosphor, because the distance between the dots is very small, the human eye will produce three primary colors of light mixed with the color feeling. This is the spatial summation color mixing method.

RGB lights

In secondary school physics class we may have done the prism test, white light through the prism is broken down into a variety of colors gradually transition of the color spectrum, the colors in the order of red, orange, yellow, green, green, blue, purple, which is the visible spectrum. 

The human eye is most sensitive to red, green and blue, the human eye is like a three-color receiver system, most of the colors can be generated by red, green and blue in different proportions of the synthesis. Similarly most of the monochromatic light can also be decomposed into red, green and blue three color light. This is the most basic principle of colorimetry, that is, the principle of three primary colors. 

The three primary colors are independent of each other, any one of the primary colors can not have the other two colors synthesized. Red, green and blue are the three primary colors, these three colors synthesized the widest range of colors. Red, green and blue three base colors in accordance with different proportions of the synthesis of mixed colors called additive color mixing.

RGB vs RGBW LED Strip

RGB LED string lights has been around for a while now and has opened the door to previously unheard-of lighting possibilities, allowing not only a wide range of customisable colours but also the ability to cut and join any length to create totally unique shapes. In response to popular demand though, there’s now a new kid on the block, RGB+W, which adds an extra white chip into the mix. Why might you need this? Read on.

RGB LED string lights have been on the market for a while now and have been a great solution for previously unheard of accent lighting features. RGB strip lights have opened the door to creative and colorful LED installations. 

These LEDs strips give customers a wide range of customizable color for completely unique lighting installations. Due to the popularity of RGB LED strip lights, a new tape light technology is not available! RGB+W LED strip lights takes the existing RGB and pairs white LED diodes to the mix. This article addresses the differences between RGB and RGB+W LED tape light and why/when you may want one over the other.

led string lights

What’s the difference between RGB and RGBW LED strip?

Standard rgb lighting uses a 3-in-1 LED chip made up of red, green and blue chips. It can produce a wide range of colours by mixing the three and looks almost white with all three at full brightness. RGB+W LED strip uses either a 4-in-1 LED chip that has a white chip as well as red, green and blue or an RGB chip alongside a white chip.

Why would you want an extra white chip? 

Although rgb lighting can produce a colour close to white, a dedicated white LED provides a much purer white tone and allows you the option of an extra warm or cool white chip. The extra white chip also provides extra scope for colour mixing with the RGB chips to create a huge range of unique shades.

Which is better?

RGB+W is undoubtedly a much more flexible product than standard RGB outdoor light string which looks a little crude alongside RGB+W. Inevitably  it is of course a bit more expensive but you are getting a much more capable product. 

If all you’re after are basic RGB colours with no requirement for a proper white then basic RGB outdoor light string is generally more cost effective, however if you do need white (for example for task lighting) then RGB+W is a better bet. 

Are the controllers different?

Yes. RGB+W lighting controllers have five outputs, one for each colour and one for power. As rgb light has one less chip, it only requires four. The functionality of the control also has to be different to control the white part of the LED in RGB+W.

Is RGBW more difficult to install?

No. The extra chip makes no difference – as long as you choose the correct controller then it’s no more complex than rgb light. In terms of control it may be a little more complex as there are extra functions but once set up it’s easy.

rgb led lights

What’s the difference between RGB and RGB+W LED Strip Lights?

Market uses a 3-in-1 5050 LED chip that is made up of red, green, and blue LED diodes. These LED strips can produce a wide range of colors by mixing the three, including an almost white look when LED colors are at full brightness.

RGB+W LED Strip Lights

The new  RGB+W features red, green, and blue LEDs, but adds a dual LED chip design that features a white 2835 LED that is paired with each of the RGB diodes. With the additional white LED chip, the RGB+W LED strip light can produce a wide range of vibrant colors, along with soft-bright (3000K) white, or a combination of white and RGB.

While RGB can produce color that is close to white, the dedicated white LED chip provides a pure white tone that is better for the task and accent lighting, when color is not needed. The extra white chip also allows the LED strip to produce a unique mix of RGB and color lighting.

Which is Better?

RGB+W tape light is undoubtedly a much more flexible option than standard RGB LED strips. The 24 Volt RGB+W tape light is slightly more expensive than RGB but is better for a broader set of installations and improved functionality. 12 Volt RGB tape light is generally more cost effective. 

This is a good lighting option for those looking for vibrant colors, where pure white would not be necessary or for customers with budget constraints.

How to Control RGB & RGB+W Strip Light

RGB and RGB+W LED strip lights use slightly different controls. RGB has four outputs (red, green, blue, power), while the RGB+W (red, green, blue, white, power) tape has five outputs. Armacost Lighting’s ProLine and SlimLine wireless switch controls are offered in both RGB and RGB+W options. They are available in traditional wireless controls and in Wi-Fi / smart controls.

The RGB+W LED controls will work with RGB tape light by simply not wiring the W connection. However, RGB controls will not work with RGB+W strip lights.

Both RGB and RGB+W LED tape light are low-voltage and require an LED driver or power supply (as well as a controller) to operate. They are very popular for under cabinet lighting.

Why RGB is so popular?

RGB outdoor light strings are highly popular because they’re: Safe. RGB lights are free of harmful ultraviolet and infrared light. You can look at them for extended periods, or use them for hours at a time, without worrying about your eyesight.

Although RGB outdoor light strings can produce a colour close to white, a dedicated white LED provides a much purer white tone and allows you the option of an extra warm or cool white chip.

RGB stands for Red, Green and Blue. Together, these colors of light make up the entire color palette on digital screens (like TVs and digital cameras). RGB is the best choice for anything online, like your website, ad posters or banners, and logos.

What is RGB?

An RGB LED is an LED module that can produce almost any color using these three primary additive colors: Red, Green and Blue. The simplest version of an RGB LED has a combination of 3 separate light-emitting diodes in one package, housed under a clear protective lens. This LED package will have 4 pins, one for each of the three colored diodes and one common anode (+) or cathode (-).

The 3 primary color LEDs use the principal of additive color mixing we talked about above to make more colors than we can imagine. LEDs are dimmable by nature which allows each red, green and blue color to produce all the different hues of that color.

Technically, each colored LED can produce 256 shades. It takes a high quality and premium DMX controller to actually get every shade possible but we will go over that more in the controllers section. For now, you can see that light manufacturers combine the 3 primary LEDs with their 256 shades (256 x 256 x 256) to come up with the ‘16.7 million different colors’ slogan that so many RGB lights come with.

So how does an RGB LED create the different color combinations? It is as simple as adjusting the brightness of each LED. Increase the brightness of red and blue LEDs while lowering that of green to make purple. Turn down the blue LED and turn up the red and green LEDs to make yellow. You get the deal….the color wheel below demonstrates this process and is what you can expect to see on many RGB Control Smart Phone Apps.

Our RGB ring string light can be controlled with 2.4G Beacon remote control or remotely using the integrated Wifi / Bluetooth system compatible with the “Tuya” app.

RGB LEDs are the newest technology to use in today’s photo, video and film industry and represent the best addition for anyone to be taking advantage of.

RGB comes from Red, Green and Blue which are the primary colors of the additive color system. RGB lighting enables the user to create millions of different colors based on these primary colors.

The basic color mixing chart gives you an idea of what combinations to make in order to produce different colors.

These are ilustrated as following:

Red + Green = Yellow
Green + Blue = Cyan
Blue + Red = Magenta
