ABSTRACT:
A LED full-color lighting device contains a control unit, a light source unit, and a light display unit. The control unit relies on at least a potentiometer to apply various voltages to constant current sources, which in turn individually vary the current conducting through the red, green and blue LEDs of the light source unit, so as to deliver light of various colors. The colored light emitted from the light source unit can be easily and conveniently adjusted to fit a user's specific preference and mood. Colored patterns or textures can be formed on the light display unit so that the color of the light of the light source unit would mix with the colors of the patterns or textures to produce a visual effect as if some of the patterns or textures are changed.
