6 . The lens structure as recited in claim 5 , wherein each of the protruding portions which extends onto the second contacting surface has a height difference with respect to the second contacting surface to define a recess, and each of the protruding portions has an inclined surface inclined towards the second contacting surface.

7 . The lens structure as recited in claim 6 , wherein the acrylate adhesive is further located on the inclined surface of each of the protruding portions and within the recess.

8 . A lens structure comprising:

a lens cone comprising at least one contacting structure;

at least one lens disposed within the lens cone and abuts against the contacting structure, and the lens has a first contacting surface and a side surface connected to the first contacting surface; and

an adhesive located between the contacting structure of the lens cone and the first contacting surface of the lens and between the contacting structure of the lens cone and the side surface of the lens.

9 . The lens structure as recited in claim 8 , wherein the adhesive comprises an UV adhesive, a moisture-curable adhesive, a polyurethane resin adhesive, or an acrylic bonding adhesive.

10 . The lens structure as recited in claim 8 , wherein the surface contacted by the lens cone, the lens, and the adhesive is defined as an interface.

11 . The lens structure as recited in claim 10 , wherein the contacting structure comprises a second contacting surface and a peripheral side wall connected to the second contacting surface.

12 . The lens structure as recited in claim 11 , wherein the interface is located between the second contacting surface of the contacting structure and the first contacting surface of the lens and between the peripheral side wall of the contacting structure and the side surface of the lens.

13 . The lens structure as recited in claim 11 , wherein the lens cone further comprises a wall and a plurality of protruding portions which are separated from each other and located on the wall, wherein the protruding portions are connected to the peripheral side wall of the contacting structure, and each of the protruding portions has an inclined surface inclined towards the second contacting surface.

14 . The lens structure as recited in claim 11 , wherein the contacting structure further comprises a plurality of protruding portions which are separated from each other and extended from a side of the peripheral side wall which is relatively away from the second contacting surface onto the second contacting surface, and the interface is located between the protruding portions of the contacting structure and the first contacting surface of the lens and between the protruding portions of the contacting structure and the side surface of the lens.

15 . The lens structure as recited in claim 14 , wherein each of the protruding portions which extends onto the second contacting surface has a height difference with respect to the second contacting surface to define a recess, and each of the protruding portions has an inclined surface inclined towards the second contacting surface.

16 . The lens structure as recited in claim 15 , wherein the adhesive is further located on the inclined surface of each of the protruding portions and within the recess.

17 . A manufacturing process of a lens structure comprising:

providing a lens cone comprising a contacting structure;

disposing a adhesive at a peripheral side wall of the contacting structure; and

disposing a lens within the lens cone and abutting the lens against the contacting structure, wherein the adhesive is located between a side surface of the lens and the peripheral side wall of the contacting structure, and the coverage area of the adhesive accounts for more than 70% of the surface area of the side surface.

18 . The manufacturing process of the lens structure as recited in claim 17 , wherein the surface contacted by the lens cone, the lens, and the adhesive is defined as an interface, and the lens has a first contacting surface and a side surface connected to the first contacting surface, and the contacting structure comprises a second contacting surface and a peripheral side wall connected to the second contacting surface.

19 . The manufacturing process of the lens structure as recited in claim 18 , wherein the interface is located between the second contacting surface of the contacting structure and the first contacting surface of the lens and between the peripheral side wall of the contacting structure and the side surface of the lens.

20 . The manufacturing process of the lens structure as recited in claim 18 , wherein the contacting structure further comprises a plurality of protruding portions which are separated from each other and extended from a side of the peripheral side wall which is relatively away from the second contacting surface onto the second contacting surface, and the interface is located between the protruding portions of the contacting structure and the first contacting surface of the lens and between the protruding portions of the contacting structure and the side surface of the lens.
