a white light emitting diode is provided , which includes a reflective mirror arranged on the light emitting path of a blue or an ultra violet led die at an appropriate angle . phosphors are coated on the reflective mirror , the emitting plane of the led , or both so that the phosphors are excited by the blue or uv lights emitted by the led die to produce white lights . the present invention provides a white led having a long lifetime and a uniform light color by separating the phosphors from the led die , and by allowing the lights emitted from the led die to undergo several excitations with the phosphors .
