A method for packaging LEDs includes steps of: forming a substrate with a rectangular frame, a plurality of first and second electrode strips received within the frame and alternately arranged along a width direction of the frame; forming a carrier layer on each pair of the first and second electrode strips, the carrier layer defining a plurality of recesses; arranging an LED die in each recess and electrically connecting the LED die with first and second electrodes; forming an encapsulation in each recess to cover the LED die; and cutting the first and second electrode strips along the width direction of the frame to obtain a plurality of separated LED packages each including the first and second electrodes, the LED die, the encapsulation and a part of the carrier layer.
