A fiber bundle mixed R-G-B white LED package incorporating LEDs, an LED container and a fiber bundle, the fiber bundle being hermetically sealed to the LED container, enclosing Nitrogen, for thoroughly mixing colored light from LEDs and converting colored light in to white light and directing the beam of light emerging the exit face of the fiber bundle in any desired angle. Colored light from different color LEDs get pre-mixed inside the container through multiple reflections at the walls of the container and enter the fibers and undergo total internal reflections at the inner walls of the fibers and thus all the remaining unmixed or partly mixed light get mixed thoroughly and emerge the exit face of the fiber bundle as white light. Multiplicity of fiber mixed R-G-B white LED package can be employed for manufacturing (i) backlight for Liquid Crystal Displays (ii) large area bill board displays (iii) light sources for consumer lighting (iv) light sources for automobile lighting and (v) light sources for bridge lighting.
