LAMP CHAIN, METHOD AND THE TOOLING FOR MAKING THE SAME

摘要

The present invention relates to a method for making a lamp chain, comprising the following steps: a) providing a tooling (7) provided with a cavity (8) therein, wherein multiple lens-like holes (9) spaced apart from each other at a predetermined distance are formed in the bottom of the cavity (8); b) placing a circuit board (3) mounted with multiple illuminants (4) in the cavity (8) and keeping the circuit board (3) away from the bottom of the cavity (8) at a predetermined distance; wherein each lens-like holes (9) correspond to the positions of the each illuminants (4) at the circuit board (3); c) injecting glue into the cavity (8) until the glue fully fills the cavity (8); and d) solidifying the glue. The present invention also relates to a corresponding lamp chain. The present invention can realize at low cost and high efficiency optical properties of a lamp, especially adjustment of light distribution.
