Abstract:
1. A method of packaging LED chips package structure, comprising: providing a substrate unit, wherein the substrate unit has a substrate body, and a positive electrode trace and a negative electrode trace respectively formed on the substrate body; arranging a plurality of LED chips on the substrate body via a matrix method to form a plurality of longitudinal LED chip rows, wherein each LED chip has a positive electrode side and a negative electrode side respectively and electrically connected with the positive electrode trace and the negative electrode trace of the substrate unit; longitudinally and respectively covering a plurality of stripped package colloids on the longitudinal LED chip rows via a first mold unit, wherein each stripped package colloid has a plurality of colloid cambered surfaces that form on a top surface thereof and correspond to the LED chips; transversely cutting the stripped package colloids along a line between each two adjacent and longitudinal LED chips to form a plurality of package colloids that are separated from each other and respectively covered on the corresponding LED chips, wherein a top surface of each package colloid is the colloid cambered surface and each package colloid has a colloid light-emitting surface formed in front of the corresponding colloid cambered surface; respectively covering and filling a frame unit on the substrate body, on the package colloids, and between each two adjacent package colloids via a second mold unit; and transversely cutting the frame unit and the substrate body along a line between each two adjacent and longitudinal LED chips to form a plurality of light bars, wherein each light bar has a frame layer for exposing the colloid light-emitting surfaces of the package colloids.
