Abstract:
An LED lamp cover structure containing luminescent material and its fabrication methods are described. The LED lamp cover is comprised of a first lens cap providing the outer surface of the lamp cover, a second lens cap providing the inner surface of the lamp cover, and an encapsulating layer sandwiched between the lens cap providing the outer surface of the lamp cover and the lens cap providing the inner surface of the lamp cover, which is mixed with luminescent material for wavelength conversion.
