WHITE LIGHT EMITTING DIODE WITH SINGLE CRYSTAL PHOSPHOR AND THE MANNER OF PRODUCTION

摘要

According to the invention, the diode with a single crystal phosphor placed over the chip comprises the fact that the single crystal phosphor, created by LnYAG and/or YAP and/or GGAG hosts, doped with the atoms selected from the Ce3+, Ti, Cr3+, Sm2+, B3+, Gd3+ or Ga3+ group, when the Lu3+, Y3+ and Al3+ atoms can be replaced in the host up to the amount of 99.9% with the B3+, Gd3+ or Ga3+ atoms. The composition and manner of production of the phosphor, treatment and shape of its surface and construction of the whole diode ensure the extraction of the converted light in the direction from the chip itself of the diode towards the object that is being illuminated and limit the total reflection effect on the interface of the single crystal phosphor and encapsulant or single crystal phosphor and surrounding environment.
