An RGB LED strip light is a linear assembly of multi-color RGB LED packages on a flexible printed circuit board that usually comes with an adhesive backing. Although an RGB color mixing system can be implemented using separate LED packages, most RGB LED strips use integrated LEDs which incorporate red, green, and blue diodes into a single package. Integrated RGB packages exhibit good color mixing in both the near and the far field, whereas products that use individually packaged LEDs does not exhibit good color mixing in the near field. At a very close range to the light strip, the beams from the LEDs will be separate and different colors are clearly visible.
