LED pixel point source compare with LED rainbow tube
Now we will started on an analysis the application and control module of LED pixel point source and LED rainbow tube.

1 Application of point source : application of LED color screen display principle the pixel amplification. Reducing the overall cost, each module is a  color LED pixel.
Application environment, bar, KTV , stage ,exhibition hall , shopping malls , as the music melody display,Background wall decoration , wall advertising etc…

Control module of point source: According to the DMX512 protocol to bring up WS2801IC LED  pixel module through DMX controller.

2 Application of LED rainbow tube: each lamp is composed of color pixels(RGB) , each color pixel produces 256 gray levels change. Application environment decorative lighting overpass guardrail , river , building walls and other different places. The energy
saving can also luminous intensity by adjusting LED PWM devices. Control module of LED rainbow, base on the RGB　tricolor light mixing principle of regulating a variety of colors , and then control to achieve a display results by MCU intellgent.
