Abstract: The present invention relates to the technical field of LED packaging, in particular to an easily-assembled COB lamp bead, a support for the lamp bead, a method for manufacturing the lamp bead and an easily-assembled LED module using the lamp bead. For the LED lamp bead provided by the present invention, as a first metal welding layer is provided on the bottom surface, it is just required to directly weld the lamp bead in a heat sink during assembling. Due to a power-taking slot formed of a positive plate and a negative plate in a matched manner, it is just required to insert one end of a driving circuit board, having a conductive terminal, into the slot during assembling. Hence, the whole assembling process is very simple, and both the efficiency and quality of assembling are effectively improved.
