[specific embodiment]

The utility model is described in detail below with reference to Fig. 1 and Fig. 2.

As depicted in figs. 1 and 2, the utility model relates to a kind of lens module 100, the lens module 100 includes having The lens barrel 110 of accommodating space 111, the lens set 120 being contained in the accommodating space 111 and it is sequentially arranged in the lens set 120 image side and optical filter 130, bracket 140 and the sensor 150 being located at outside the accommodating space 111.

Wherein, the bracket 140 includes the roof 141 for forming light hole 141a, and the roof 141 includes towards object side First surface 141b, with the first surface 141b second surface 141c being oppositely arranged and connect the first surface 141b The third surface 141d of the light hole 141a is set as with the second surface 141c and enclosing.

Wherein, above-mentioned lens module 100 further includes the first light absorbing layer 160, and first light absorbing layer 160 is located at described On second surface 141c, and first light absorbing layer 160 is in honeycomb.

That is, as shown in Figure 1, the first light absorption of a flood can be set on the second surface 141c Layer 160, it is of course also possible to which some first light absorbing layer 160 is arranged on second surface 141c, is not limited thereto, can With the degree of the covering second surface 141c of required first light absorbing layer 160 determine according to actual needs.

Therefore, the lens module 100 of the present embodiment structure, is provided with the first light absorbing layer on second surface 141c 160, and first light absorbing layer 160 is in honeycomb, therefore, the light being incident on from the object side of lens set 120 enters branch When in frame 140, the light reflected can be entered in cellular first light absorbing layer 160, so that some light can With the multiple reflections in the first light absorbing layer 160, and then luminous energy can be weakened, reduce the stray light of lens module 100, improve mirror The image quality of head mould group 100.

As depicted in figs. 1 and 2, the lens module 100 further includes the second light absorbing layer 170, second light absorbing layer 170 are located on the third surface 141d, and second light absorbing layer 170 is in honeycomb.

Specifically, as shown in Figure 1, the second light absorbing layer 170 can all cover third surface 141d, certainly, the second light Absorbed layer 170 can also partially cover third surface 141d, be not limited thereto, can be required determine according to actual needs The degree of third surface 141d shown in the covering of second light absorbing layer 170.

Therefore, the lens module 100 of the present embodiment structure is provided with the second light absorbing layer on the 141d of third surface 170, and second light absorbing layer 170 is in honeycomb, therefore, the light being incident on from the object side of lens set 120 enters branch When in frame 140, the light reflected can be entered in cellular second light absorbing layer 170, so that some light can With the multiple reflections in the second light absorbing layer 170, and then luminous energy can be weakened, reduce the stray light of lens module 100, improve mirror The image quality of head mould group 100.
