Beschreibung
Zusammenfassung:	The invention discloses a high-power white LED. The LED comprises a base, a carrier and an LED chip fixed on the carrier, wherein the base is provided with a lens wrapping the carrier and the LED chip, the lens is stamped with mixed fluorescent powder and silicon resin. Compared with the prior art, the high-power white LED adopts a lens shell cover stamped with mixed fluorescent powder and silicon resin for encapsulating the LED chip and preventing the LED from contacting the fluorescent power directly, so heat generated during the operation of the LED does not act on the fluorescent and the light emitting effect and the service life of the LED chip are improved.
