Patent ID: 7382091

Claim:
A white light emitting diode using phosphor excitation, comprising: a circuit board having a positive electrode, a negative electrode, and a light emitting diode die, the light emitting diode die being driven to emit specific color lights when an external voltage is applied onto the positive electrode and the negative electrode; a reflective mirror arranged on an emitting path of the specific lights emitted by the light emitting diode die at an appropriate inclined angle, first phosphors being coated on an incident plane of the reflective mirror, the first phosphors configured so that white lights are produced by the specific lights' exciting the first phosphors; and a cladding encapsulating the circuit board and the reflective mirror therein, lights reflected by the reflective mirror emitting out of the white light emitting diode through a emitting plane of the cladding, wherein the light emitting diode emits the specific lights to the reflective mirror on the emitting path, and the first phosphors coated on the incident plane of the reflective mirror are excited by the specific lights to generate white lights, and the white lights are reflected by the reflective mirror and then emit through the emitting plane of the cladding.
