Abstract:
1. A lens module for being fixed to a substrate by UV glues, comprising: a lens barrel having a hollow receiving groove for receiving an optical lens therein; and a lens holder integratedly formed at a bottom of the lens barrel, the lens holder defining a containing cavity communicating with the receiving groove and penetrating through a bottom thereof to form a plurality of inner walls surrounding the containing cavity, the lens holder further defining a plurality of outer pillars spaced from each other and arranged apart from outer peripheries of the corresponding inner walls to define gaps therebetween, a cross-section of each outer pillar being of substantial triangle shape with an acute angle thereof pointing towards the corresponding inner wall; wherein the UV glues are distributed to a bottom of each outer pillar so that ultraviolet lights can pass through intervals between the outer pillars to irradiate and solidify the UV glues for making the lens module fixed to the substrate.
