    • 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.
    • 制造灯链的方法可以包括:a)提供在其中设置有空腔的工具,其中在空腔的底部形成有以预定距离彼此间隔开的多个透镜状孔; b)将安装有多个光源的电路板放置在空腔中,并将电路板保持在预定距离处远离腔的底部; 其中所述多个透镜状孔对应于所述电路板处的所述多个发光体的位置; c)将胶水注入空腔,直到胶完全填满空腔; 和d)固化胶。
