  • LED package structure with phosphor encapsulant layer
    Patent number: 10847690
    Abstract: An LED package structure with phosphor encapsulant layer includes an LED chip, a first encapsulant layer, and a second encapsulant layer; the first encapsulant layer covers the LED chip mixed with a first type phosphor having an excitation emission peak wavelength in a first wavelength range; the second encapsulant layer covers a first encapsulant layer mixed with a second type phosphor having an excitation emission peak wavelength in a second wavelength range. At least one of the first type phosphor and the second type phosphor is distributed in the corresponding first encapsulant layer or the corresponding second encapsulant layer in a state where the bottom concentration is higher than the top concentration.
    Type: Grant
