Abstract: A production method for a chip-type lamp bead capable of emitting polychromatic light relates to the technical field of LED lamp beads, including steps: a first process: die bonding, for fixing a chip to a supporting plate; a second process: wire bonding, for linking positive and negative electrodes of the chip to a bracket; a third process: molding, for packaging the material with an epoxy resin after prior two steps, and different light colors are achieved through matching with different phosphors; a fourth process: cutting, for cutting the molded material into single materials; a fifth process: light splitting, for splitting light in the material having been cut; and a sixth process: braiding, packaging and shipping. Multiple LED chips can be integrated inside a chip-type lamp bead, each chip can emit light independently and control different colors, and thus the same lamp bead can achieve free mixing of multiple colors.
