1. a light source is characterized in that, comprising:

  • Light emitting diode matrix, this light emitting diode matrix comprise at least two kinds of light emitting diodes that glow color is different, and each light emitting diode comprises a light-emitting diode chip for backlight unit;

    The surface coverage of said light-emitting diode chip for backlight unit has refractive index to be lower than 1.1 transparent low refractive index medium;

    Or refractive index is higher than 1.3 transparent high refractive index medium, and the thickness of this high refractive index medium is less than 50% of the circumscribed circle diameter of said light-emitting diode chip for backlight unit light-emitting area;

    The collimating element array;

    This collimating element array comprises at least one collimating element unit;

    This collimating element unit is corresponding with at least one light emitting diode, is used for the light that this at least one light emitting diode of collimation send and keeps the optical extend of the light that this at least one light emitting diode send constant basically;

    Dodging device is used for handling do homogenising from the light of collimating element array outgoing.
