  • Patent number: 11456398
    Abstract: An LED chip package structure and a method of manufacturing the same are provided. The method of manufacturing the LED chip package structure includes providing a phosphor film including a phosphor layer and an outer enclosing layer for enclosing the phosphor layer that includes a plurality of phosphor particles; removing the outer enclosing layer from the phosphor layer for exposing the phosphor layer; and then covering an LED chip with the phosphor layer. The LED chip package structure includes an LED chip and a phosphor layer for covering the LED chip. The phosphor layer includes a plurality of phosphor particles tightly connected with each other, and the phosphor layer has no non-phosphor material. Therefore, the LED chip can be directly covered by the phosphor layer without the outer enclosing layer, and the phosphor particle without the non-phosphor material can directly contact the LED chip.
