8/17/2023 0 Comments Battery led strip lights rgbNumerous RGB LEDs are mounted on the strip, usually with 4 wire traces, 3 for each color and one for a common anode. 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.Īn RGB LED strip works on this same principle. Turn down the blue LED and turn up the red and green LEDs to make yellow. Increase the brightness of red and blue LEDs while lowering that of green to make purple. So how does an RGB LED create the different color combinations? It is as simple as adjusting the brightness of each LED. ![]() 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. 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. Technically, each colored LED can produce 256 shades. LEDs are dimmable by nature which allows each red, green and blue color to produce all the different hues of that color. The 3 primary color LEDs use the principal of additive color mixing we talked about above to make more colors than we can imagine. This is called additive because all the wavelengths still reach our eyes. When all the colors are added together we see white rather than many individual colors. This is what happens when lights of different wavelengths are mixed. Additive color mixing involves creating a new color by a process that adds one set of wavelengths to another set of wavelengths. ![]() This model is only ONE of the two models that exist in the visible world, the one we will be paying attention to with lighting is the Additive Model. ![]() Subtractive color mixing occurs when we mix paints, dyes, or pigments…Therefore it is big in printing, dyeing clothes, etc. Subtractive color mixing involves creating a new color by removing wavelengths from light with a broad spectrum of wavelengths. In the Subtractive Model, the absence of color is white. Remember back in school when mixing blue and yellow paint on paper made green? This type of color mixing is known as the subtractive model in which the primary colors are red, blue and yellow, mixing them makes the secondary colors.
