The lens assembly 10 is formed on the circuit board 20 and electrically connected to the circuit board 20, the diffractive optical element 30 is formed at an end of the lens assembly 10 away from the circuit board 20, the protective connector 40 is connected to the lens assembly 10, and the UV glue 50 is used for fixing the lens assembly 10, the diffractive optical element 30 and the protective connector 40.

The lens assembly 10 includes a lens barrel or voice coil motor, a lens holder, a lens, and the like.

In this embodiment, referring to fig. 2, the lens assembly 10 includes an opening groove 11. The open slot 11 includes a first inner wall 111 and a second inner wall 112 opposite to the first inner wall 111. Two first receiving grooves 12 and two second receiving grooves 13 are formed by recessing the first inner wall 111 and the second inner wall 112 of the open slot 11 toward the lens assembly 10, respectively. Specifically, two first receiving grooves 12 are located on the first inner wall 111, and two second receiving grooves 13 are located on the second inner wall 112. One of the first receiving grooves 12 is adjacent to the diffractive optical element 30, and the other of the first receiving grooves 12 is adjacent to the circuit board 20. One of the second receiving grooves 13 is adjacent to the diffractive optical element 30, and the other second receiving groove 13 is adjacent to the circuit board 20.

In the present embodiment, referring to fig. 3, the bottom of each of the first receiving grooves 12 and the second receiving grooves 13 has a second microstructure 14.

The protection connector 40 is used to prevent the current flowing through the lens module 100 from being overloaded.

In this embodiment, referring to fig. 2 and 4-5, the protection connector 40 includes a connector body 41, a plurality of conductive traces 42, two first conductive bumps 43 and two second conductive bumps 44. The conductive traces 42 are embedded in the connector body 41. The two first conductive bumps 43 and the two second conductive bumps 44 are respectively formed on two opposite surfaces of the connector body 41, and the first conductive bumps 43 and the second conductive bumps 44 are respectively electrically connected to one of the conductive traces 42.

The connector body 41 includes a first side surface 411 and a second side surface 42 opposite to the first side surface 411. Two of the first conductive bumps 43 are formed on the first side 411, and two of the second conductive bumps 44 are formed on the second side 412.

In the present embodiment, each of the first conductive bumps 43 and each of the second conductive bumps 44 has a plurality of first microstructures 45 at an end thereof away from the connector body 41. The second microstructure 14 is congruent with the first microstructure 45.

The first conductive block 43 and the second conductive block 44, and the first receiving groove 12 and the second receiving groove 13 respectively engaged therewith are adopted, so that the contact area between the protection connector 40 and the lens assembly 10 can be increased, and the conductive performance between the protection connector 40 and the lens assembly 10 can be increased.

The controller 70 is used for receiving a signal that light emitted from a light receiver (not shown) is weakened and controlling the internal circuit of the circuit board 20 to be disconnected, so that the light emitter 60 stops emitting light.

Specifically, the light emitted by the light emitter 60 passes through the lens assembly 10 and the diffractive optical element 30 to form an image, the light receiver receives the light and determines whether the intensity of the received light is weakened, if the intensity of the light is weakened, it means that there is light leakage in the lens module 100, at this time, the light receiver sends a light weakening signal to the controller 70, and after the controller 70 receives the light weakening signal, the controller controls the internal circuit of the circuit board 20 to be disconnected, so that the light emitter 60 stops emitting light.
