What Is RGB Lighting?
LED is a long-lasting, energy-saving, cool-running light source, and it will illuminate our world for a long time. LEDs may not excite ordinary passers-by, but the skills and new controls on these miniature light-emitting diodes will definitely be “wow” a lot. RGB lighting is one of the techniques, and its usage trend is on the rise.
But with RGB LEDs, color mixing allows for millions of colors to output from LEDs that start with just the three primary colors: red, green and blue.LEDs are dimmable by nature which allows each red, green and blue color to produce all the different hues of that color.
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.
Each colored LED can produce 256 shades.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.
