1. A method for manufacturing an LED light strip, comprising:
a feeding step, during which a light panel with a light bead is placed on a compound dripping station of a compound dripping machine in such a way that a compound-dripped surface of the light panel with the light bead faces a bottom opening of each of light-blocking compound setting grooves of a light-blocking compound setting mold, and a left light-blocking compound setting groove and a right light-blocking compound setting groove of the light-blocking compound setting mold are respectively disposed on a left side and a right side of the light bead;
a light-blocking compound dripping step, during which a light-blocking compound is simultaneously dripped into the light-blocking compound setting grooves located on the left side and the right side of the light bead by using the compound dripping machine, so as to form two light-blocking dam colloids respectively disposed on the left side and the right side of the light bead on the compound-dripped surface of the light panel; and
a diffusion compound dripping step, during which after the light-blocking dam colloids are cured such that the light-blocking dam colloids face a bottom opening of a diffusion compound setting groove of a diffusion compound setting mold, a diffusion compound is dripped into the diffusion compound setting groove by using the compound dripping machine, so as to form a diffusion colloid on the two light-blocking dam colloids respectively disposed on the left side and the right side of the light bead.
