Flat cup LED lamp bead manufacturing method and flat cup LED lamp bead

The invention relates to a flat cup LED lamp bead manufacturing method and a flat cup LED lamp bead. The manufacturing method comprises the following steps that firstly, a shell-shaped support is manufactured, and a frosted surface is machined on the cavity wall of the shell-shaped support; secondly, a light-emitting chip assembly is installed, and the light-emitting chip assembly is installed at the cavity bottom of the shell-shaped support; step 3, manufacturing a concave lens, enabling the colloid of the first dispensing to submerge the light-emitting chip assembly and to climb upwards along the frosted surface, and performing first curing to form the concave lens with an inward concave curved surface facing upwards; and 4, manufacturing the convex lens, carrying out secondary curing after the secondary dispensing is finished, and forming the convex lens with a downward convex curved surface after the secondary curing. According to the manufacturing method for the flat-cup LED lamp bead, the colloid for th
